+# Universal Online Judge
+
+## Dependence
+This is a dockerized version of UOJ. Before installation, please make sure that [Docker](https://www.docker.com/) has already been installed on your OS.
+
+The docker image of UOJ is **64-bit**, so a **32-bit** host OS may cause installation failure.
+
+## Installation
+First please download [JDK7u76](http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html#jdk-7u76-oth-JPR) and [JDK8u31](http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html#jdk-8u31-oth-JPR), and put them to `docker/jdk-7u76-linux-x64.tar.gz` and `docker/jdk-8u31-linux-x64.tar.gz`. These two compressed files are used by judge\_client for judging Java program. If you are too lazy to download these two huge files, you can simply place two empty .tar.gz files there.
+
+Next, you can run the following command in your terminal: (not the one in the `docker/` directory!)
+```sh
+./install
+```
+If everything goes well, you will see `Successfully built <image-id>` in the last line of the output.
+
+To start your UOJ main server, please run:
+```sh
+docker run -it -p 80:80 -p 3690:3690 <image-id>
+```
+If you are using docker on Mac OS or having 'std: compile error. no comment' message on uploading problem data, you could possibly use this alternative command:
+```sh
+docker run -it -p 80:80 -p 3690:3690 --cap-add SYS_PTRACE <image-id>
+```
+
+The default hostname of UOJ is `local_uoj.ac`, so you need to modify your host file in your OS in order to map `127.0.0.1` to `local_uoj.ac`. (It is `/etc/hosts` on Linux.) After that, you can access UOJ in your web browser.
+
+The first user registered after the installation of UOJ will be a super user. If you need another super user, please register a user and change its `usergroup` to "<samp>S</samp>" in the table `user_info`. Run
+```sh
+mysql app_uoj233 -u root -p
+```
+to login mysql in the terminal.
+
+Notice that if you want only one judge client, then everything is ok now. Cheers!
+
+However, if you want more judge clients, you need to set up them one by one. First run:
+```sh
+./config_judge_client
+```
+and answer the questions.
+
+* uoj container id: the container id of the main server.
+* uoj ip: the ip address of the main server.
+* judger name: you can take a name you like, such as judger, judger\_2, very\_strong\_judger. (containing special characters may cause  unforeseeable consequence.)
+
+After that, a sql command is given, we will talk about it later.
+
+Next, we need to run:
+```sh
+./install_judge_client
+```
+to build the docker image. If you want to run judger at the same server, you just need to run
+```sh
+docker run -it <image-id>
+```
+And, you need to complete the sql command given just now with the ip address of the judger docker, and modify the database. To someone who do not know how to get the ip address of a docker container, here is the answer:
+```sh
+docker inspect --format '{{ .NetworkSettings.IPAddress }}' <container-id>
+```
+
+Or, if you want to run judger at different server, you need to copy the image to the other server, and run
+```sh
+docker run -p 2333 -it <image-id>
+```
+Similarly, you need to complete the sql command and modify the database. This time, you need to fill with the ip address of the host machine of the judger docker.
+
+You may meet many difficulties during the installation. Good luck and have fun!
+
+## Notes
+
+mysql default password: root
+
+local\_main\_judger password: judger
+
+You can change the default hostname and something else in `/var/www/uoj/app/.config.php`. However, not all the config is here, haha.
+
+## More Documentation
+As you know, my Yingyu is not very hao. Suoyi only the README file is En(Chi)nglish for internationalization.
+
+More documentation is here: [https://vfleaking.github.io/uoj/](https://vfleaking.github.io/uoj/)

+# 开发
+听说你想写代码？
+
+svn://local\_uoj.ac/uoj 和 svn://local\_uoj.ac/judge_client 欢迎你（如果你没改 UOJ 的 hostname 的话），这是两个 svn 仓库，至于 svn 仓库权限问题……你需要手工加一下……
+
+在 /var/svn/uoj/conf/passwd 这个文件中你可以加一行
+<pre>
+uoj = 666666
+</pre>
+来增加一位名为 "<samp>uoj</samp>"，密码为 "<samp>666666</samp>" 的 svn 仓库管理员。
+
+之后你就可以随意用 svn 玩耍了哇咔咔……
+
+在本地写完之后，如果你想与别人分享，你可以把代码再放到 git 中（什么鬼？）再 push 到 github。
+
+如果你想更新的东西已经不局限于网站代码，还想对数据库、文件系统之类的折腾一番，请在 app/upgrade 目录下建立文件夹，举个例子，叫 `2333_create_table_qaq`。即，以一串数字开头，后面加一个下划线，再后面随便取名字吧，仅能包含数字字母和下划线。
+
+在这个文件夹下你可以放一些小脚本。大概 UOJ 运行这些小脚本是这么个逻辑：
+```php
+if (is_file("{$dir}/upgrade.php")) {
+	$fun = include "{$dir}/upgrade.php";
+	$fun("up");
+}
+if (is_file("{$dir}/up.sql")) {
+	runSQL("{$dir}/up.sql");
+}
+if (is_file("{$dir}/upgrade.sh")) {
+	runShell("/bin/bash {$dir}/upgrade.sh up");
+}
+```
+你只需要在 /var/www/uoj/app 下执行 `php cli.php upgrade:up 2333_create_table_qaq` 就可以运行了，这个运行过程我们称为 `up`。
+
+请务必再写一下还原的小脚本，我们称为 `down`。写完代码后你需要保证 `up` 再 `down` 能回到原来的系统。与 `up` 类似，你需要执行 `php cli.php upgrade:down 2333_create_table_qaq`，执行 `down` 的逻辑如下：
+```php
+if (is_file("{$dir}/upgrade.php")) {
+	$fun = include "{$dir}/upgrade.php";
+	$fun("down");
+}
+if (is_file("{$dir}/down.sql")) {
+	runSQL("{$dir}/down.sql");
+}
+if (is_file("{$dir}/upgrade.sh")) {
+	runShell("/bin/bash {$dir}/upgrade.sh down");
+}
+```
+
+在数据库中，UOJ 会记录自己已经加载了哪些 upgrade，当你执行 `php cli.php upgrade:latest` 的时候，UOJ 会把所有已经在 app/upgrade 文件夹下但还没有加载的 upgrade 都给 `up` 一下，并且是按前缀上的那一串数字从小到大执行。所以写好了这种小 upgrade 之后，你就可以跟别人分享了！
+
+不过关于架构什么的介绍我还是先

+请参见 [README.md](https://github.com/vfleaking/uoj/blob/master/README.md) 来安装。
+
+嘿嘿现在我假设你已经是超级管理员了！
+
+那么你就可以新建题目了！
+
+看看看，problem/1 这个文件夹，里面有一道样题，赶紧动手上传！（啊感觉我应该多给几道样题的）
+
+关于如何传题请参见[题目文档](problem/)
+
+啊如果你在 “与svn仓库同步” 的过程中发现 <samp>compile error</samp> 并且还说 <samp>no comment</samp> 的话……多半是……UOJ 尝试 ptrace 然而 ptrace 被禁了……
+
+被禁了可能是被 docker 禁了，可以加一句 `--cap-add SYS_PTRACE` （见 [README.md](https://github.com/vfleaking/uoj/blob/master/README.md)）……要是这样不能解决问题……是 Ubuntu/openSUSE 环境嘛？请尝试用下面的命令阻止 AppArmor 对 docker 的行为产生影响。当然把第二行加到 `rc.local` 里就不用每次重启都输入一遍啦~（详细解释戳 [→ 这里](https://github.com/docker/docker/issues/7276)）
+
+```sh
+sudo apt-get install apparmor-utils
+aa-complain /etc/apparmor.d/docker
+```
+
+要是这样还是不能解决问题……估计就是被黑恶势力禁掉了。。。大概就不是咱们这边的锅了，找找是哪个黑恶势力禁的吧。。。
+
+另：如果上述方法不能解决 ptrace 问题也可以考虑使用 `--privileged`，但是这么做会导致 docker 失去其原有的隔离性而带来潜在的风险，不建议在生产环境中使用。
+
+传题都没问题的话，感觉就可以愉快使用 UOJ 了！
+
+## 教练我还想折腾！
+
+嗯！来来来我们来折腾一波。
+
+有个很厉害的配置文件，在 /var/www/uoj/app/.config.php 里，你可以配置一波……一个完全体如下：（有可能本文档没有跟上代码更新的速度，请以旁边的那个 .default-config.php 为准）
+
+```php

+];
+```
+
+### 域名
+如果你想使用自己的域名，改 config 即可。
+
+如果你是搭校内网站这种的，可能没有 DNS。你可以选择自己搭校内的 DNS 解析，或者自己改 hosts。
+
+或者你想成为一条咸鱼，可以直接在 config 里的 host 那里写 ip。
+
+谜之声：为什么博客用不了？
+
+嗯。。。博客的话需要给每个用户的博客域名进行解析……最好是用泛解析解决。如果没这条件，我帮你点根蜡烛 23333……期待有为青年码一个“博客以子域名还是子目录形式出现”的开关。
+
+### 邮箱
+noreply 邮箱的目的是发一些莫名其妙的邮件，比如 svn 密码和 “找回密码”。
+
+你可以随便找一个邮箱小号把账号密码塞这里，但是记得查查邮件服务商的 SMTP 服务器名和端口。以及，有些邮箱是需要手动开启某个开关才能允许 SMTP 发送邮件的。

+# 维护
+
+## 数据可持久化
+
+（我并不是在说函数式线段树233）
+
+有同学表示重启后 docker 丢失了数据。在这里要科普下 docker 的 image 和 container 的概念。
+
+`run` 命令的功能是读一个 image 并运行，跑起来的 image 是一名光荣的 container，跑完的 container 还是一名光荣的 container。
+
+所以当你关掉了你的 container 之后，使用 `run` 命令试图让它复活是不对的。。。
+
+首先，你需要
+```sh
+docker ps -a
+```
+来查看所有正在运行或运行结束的 container，找到你刚才掐掉的那个（通常就是第一个），然后复制下它的 container id。然后：
+```sh
+docker restart <container-id>
+```
+这家伙就在后台默默跑起来了！如果你想让它回到前台，请用
+```sh
+docker attach <container-id>
+```
+当当！复活了！你以为丢失了的数据都回来了！（container 其实可以起名的，这种进阶用法自己探索吧233）
+
+## 更新
+
+当 github 上有更新的时候，如何更新自己本地的版本呢？
+
+求看眼[开发](/dev/)最前面几行关于使用 svn 仓库的。
+
+嗯好，假设你已经看完了。如果是 uoj 和 judge_client 的更新，那么你可以 svn checkout 一下，然后把 git 里的新版本 commit 上去……不过你以前 checkout 过的话就可以留着那个文件夹，下次就不用重新 checkout 了。
+
+随着 UOJ 代码的更新，可能会有一些数据哇文件系统哇之类的更新，这种会被打包放在 app/upgrade 目录下。你只需要在 /var/www/uoj/app 下执行 `php cli.php upgrade:latest` 就好啦！

+# 题目
+## 上传题目
+新建题目只有超级管理员有权限，所以想加题先要联系超级管理员君，点一下题库右下方的 “新建题目” 按钮。
+
+新建题目后，超级管理员或该题目的题目管理员可以看到题目后台。后台分为三个选项卡：
+
+1. 编辑：题面编辑页面
+2. 管理者：题目管理员列表管理页面
+3. 数据：题目数据管理页面
+
+当然还有最后个 “返回” 选项卡退出后台。下面将逐一介绍这三个选项卡。
+
+###编辑
+该页面可以对题面本身进行编辑，还可以管理题目的标签。
+
+####编辑题面
+题面用 Markdown 编写。
+
+理论上题面是可以自由编写的，但还是有一些推荐的格式。可参照 UOJ 上对应类型的题面（传统题，交互题，提交答案题等）
+
+一些推荐的规则：
+
+1. 中文与英文、数字之间加一个空格隔开。
+2. 输入输出样例用 `<pre>` 标签包围，并且以一个空行结尾。（方便大家复制样例到终端后不用再打回车）
+3. 题面中最高级标题为三级标题。这是因为题目名称是二级标题。
+4. 名称超过一个字符的数学符号要用 mathrm。例如 `\mathrm{sgn}`， `\mathrm{lca}`。
+4. 注意 `\max`, `\min`, `\gcd` 都是有现成的。
+5. 注意 xor 这种名称超过一个字符的二元运算符请用 `\mathbin{\mathrm{xor}}`。
+6. 一行内的计算机输入输出和常量字符串表达式请用 `<samp>` 标签，例如 `请输出 “<samp>NO SOLUTION</samp>”`， `<samp>aaa</samp> 中有三个 <samp>a</samp>`。
+7. 一行内的计算机代码请用 <code>`</code> 括起来，就像上面的规则那样。
+
+可参考下面这个例子：
+```markdown
+读入一个整数 $n$，表示题目中提到的 $3$ 位大爷 AC 的总题数。请输出他们分别 AC 的总题数。如果你不能正确读入，那么将获得 $0$ 分。前 $3$ 个测试点你正确读入即可获得 $6$ 分，第 4 个测试点你正确读入只能获得 $3$ 分。如果你不会做这道题，请直接输出 “<samp>WOBUHUI</samp>”
+
+下面有一个样例：
+<pre>
+233
+
+</pre>
+```
+
+
+####编辑标签
+只需要用英文逗号隔开标签填入文本框就行。
+
+推荐你使用如下几条规则填写标签：
+
+1. 标签的目的是标出题目类型，方便用户检索题目。一般来说，标签顺序基本为从小范围到大范围。
+2. 最前面的几个标签是这题所需要的前置技能，这里假定 “二分查找” 之类过于基础的技能选手已经掌握。
+3. 接下来是这道题的大方法，比如 “贪心”、“DP”、“乱搞”、“构造”、“分治”……
+4. 接下来，如果这道题是非传统题，用一个标签注明非传统题类型，比如 “提交答案”、“交互式”、“通讯”。
+5. 接下来，如果这道题是模板题，用一个标签注明 “模板题”。
+6. 接下来，如果这道题是不用脑子想就能做出的题，例如 NOIP 第一题难度，用一个标签注明 “水题”。
+7. 最后，如果这题的来源比较重要，用一个标签注明。比如 “UOJ Round”、“NOI”、“WC”。
+8. 前置技能中，“数学” 太过宽泛不能作为标签，但 “数论” 可以作为前置技能。
+9. 如果有多个解法，每个解法的前值技能和大方法都不太一样，那么尽可能都标上去。
+10. “乱搞” 标签不宜滥用。
+
+
+###管理者
+只有题目管理员和超级管理员才能看到后台，但只有题目管理员才能管理题目数据。
+
+可以通过这个页面增加或删除题目管理员。
+
+###数据
+UOJ 使用 svn 管理题目数据，svn 仓库地址可以在本页面上找到。当你点了本页面的某个按钮后，UOJ 将把 svn 密码发送到你的邮箱。这个 svn 密码是不随题目变化而变化的。
+
+但是，初始时 UOJ 是没有配置过用于给大家发邮件的邮箱的。所以如果你还没有配置过，请直接在数据库的 user\_info 表中找到 svn\_password 一栏存储的值；如果你愿意折腾一下，可以在 /var/www/uoj/app/.config.php 里配置一下邮箱，详情见[安装](/install/)咯～
+
+1. 下载 svn，即 subversion。如果是 win 可以用 TortoiseSVN，如果是 ubuntu 直接 apt-get 一发，也可以用 smartsvn。
+2. 学习怎么使用 svn。（蛮好懂的吧，会用 checkout，add，remove，commit 什么的就行了）
+3. 在题目数据管理页面，获取 svn 密码。
+4. checkout 这道题。
+5. 在你的 working copy 下，建立文件夹 1，然后在 1 这个文件夹下放置题目数据什么的。
+6. 搞完之后 commit。
+7. 在网页上点“与SVN仓库同步”，就可以啦！
+
+####题目配置格式
+主要麻烦是要写个 problem.conf，下面主要介绍传统题的配置。
+
+例如：
+
+<pre>
+use_builtin_judger on
+use_builtin_checker ncmp
+n_tests 10
+n_ex_tests 5
+n_sample_tests 1
+input_pre www
+input_suf in
+output_pre www
+output_suf out
+time_limit 1
+memory_limit 256
+output_limit 64
+
+</pre>
+
+假如你 input 文件是 www1.in, www2.in, ... 这个样子，那么你需要在 problem.conf 里记录：
+
+<pre>
+input_pre www
+input_suf in
+
+</pre>
+
+output 文件同理。 
+
+extra test 是指额外数据，在 AC 的情况下会测额外数据，如果某个额外数据通不过会被倒扣3分。
+
+至于样例，样例一定是前几个额外数据，所以有一个 `n_sample_tests` 表示是前多少组是样例。你需要把题面中的样例和大样例放进额外数据里。
+
+额外数据命名形如 ex\_www1.in, ex\_www2.in, ... 这个样子。
+
+checker 是指判断选手输出是否正确的。一般来说输出结果为整数序列，用 ncmp 就够了，它会比较标准答案的整数序列和选手输出的整数序列。如果是忽略所有空白字符，进行字符串序列的比较，可以用wcmp。如果你想按行比较（不忽略行末空格，但忽略文末回车），可以使用 fcmp。如果想手写 checker，请使用 Codeforces 的 [testlib](http://codeforces.com/testlib) 库写 checker。
+
+你需要写好后命名为 chk.cpp，然后在 problem.conf 中去掉 “use\_builtin\_checker” 一行。
+
+如果你的题目的输入数据可以被检验是否满足题目要求，那么请写一个 validator。比如“保证数据随机”“保证数据均为人手工输入”等就无法检验输入数据是否满足题目要求。
+
+validator 的作用就是检查你输入数据造得是否合法。比如你输入保证是个连通图，validator 就得检验这个图是不是连通的。还是请用 testlib 写，教程还是之前提到的那个教程。写好后命名为 val.cpp 就行。
+
+另外注意时间限制**不能为小数**。
+
+#### 提交答案题的配置
+范例：
+
+<pre>
+use_builtin_judger on
+submit_answer on
+n_tests 10
+input_pre www
+input_suf in
+output_pre www
+output_suf out
+
+</pre>
+
+So easy！
+
+不过还没完……你要写个 checker。当然如果你是道 [最小割计数](http://uoj.ac/problem/85) 就不用写了。。。老样子写个 use\_builtin\_checker ncmp 就行。
+
+提答题经常会面临给部分分，请使用 quitp 函数。由于一些历史原因（求不吐槽 QAQ），假设测试点满分为 a，则
+```cpp
+quitp(x, "haha");
+```
+将会给 floor(a * round(100x) / 100) 分。是不是很复杂……其实很简单，当你这个测试点想给 p 分的时候，只要
+```cpp
+quitp(ceil(100.0 * p / a) / 100, "haha");
+```
+就行了。（好麻烦啊）
+
+假设你已经写好了，赞！
+
+但是下发的本地 checker 怎么办？
+
+首先你得会写本地 checker。如果只是传参进来一个测试点编号，检查测试点是否正确，那么只要善用 registerTestlib 就行了。如果你想让 checker 与用户交互，请使用 registerInteraction。特别地，如果你想让 checker 通过终端与用户进行交互，请使用如下代码（好丑啊）
+```cpp
+	char *targv[] = {argv[0], "inf_file.out", (char*)"stdout"};
+#ifdef __EMSCRIPTEN__
+	setvbuf(stdin, NULL, _IONBF, 0);
+#endif
+	registerInteraction(3, targv);
+```
+
+那么怎么下发文件呢？你可以在文件夹 1/ 下新建一个文件夹 download，里面放的所有东西都会打包发给选手啦～
+
+#### 交叉编译
+
+由于你的本地 checker 可能需要发布到各个平台，所以你也许需要交叉编译。交叉编译的意思是在一个平台上编译出其他平台上的可执行文件。好！下面是 Ubuntu 上交叉编译小教程时间。
+
+首先不管三七二十一装一些库：（请注意 libc 和 libc++ 可能有更新的版本）
+```sh
+sudo apt-get install libc6-dev-i386
+sudo apt-get install lib32stdc++6 lib32stdc++-4.8-dev
+sudo apt-get install mingw32
+```
+
+然后就能编译啦：
+```sh
+g++ localchk.cpp -o checker_linux64 -O2
+g++ localchk.cpp -m32 -o checker_linux32 -O2
+i586-mingw32msvc-g++ localchk.cpp -o checker_win32.exe -O2
+```
+
+问：那其他系统怎么办？有个叫 emscripten 的东西，可以把 C++ 代码编译成 javascript。请务必使用 UOJ 上的 testlib，而不是 CF 上的那个版本。由于 testlib 有些黑科技，UOJ 上的 testlib 对 emscripten 才是兼容的。
+
+[emscripten 下载地址](http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html) （建议翻墙提升下载速度）
+
+编译就用
+```sh
+em++ localchk.cpp -o checker.js -O2
+```
+
+#### 交互题的配置
+嘛……其实并没有 UOJ 内部并没有显式地支持交互式（真正的程序与程序交互的版本还没发布出来），只是提供了 require、implementer 和 token 这两个东西。
+
+除了前文所述的 download 这个文件夹，还有一个叫 require 的神奇文件夹。在测评时，这个文件夹里的所有文件均会被移动到与选手源程序同一目录下。在这个文件夹下，你可以放置交互库，供编译时使用。
+
+再来说 implementer 的用途。如果你在 problem.conf 里设置 `with_implementer on` 的话，各个语言的编译命令将变为：
+
+* C++: g++ code implementer.cpp code.cpp -lm -O2 -DONLINE_JUDGE
+* C: gcc code implementer.c code.c -lm -O2 -DONLINE_JUDGE
+* Pascal: fpc implementer.pas -o code -O2
+
+好……不管那些奇怪的选手的话，一个交互题就搞好了……你需要写 implementer.cpp、implementer.c 和 implementer.pas。当然你不想兹瓷某个语言的话不写对应的交互库就好了。
+
+如果是 C/C++，正确姿势是搞一个统一的头文件放置接口，让 implementer 和选手程序都 include 这个头文件。把主函数写在 implementer 里，连起来编译时程序就是从 implementer 开始执行的了。
+
+如果是 Pascal，正确姿势是让选手写一个 pascal unit 上来，在 implementer.pas 里 uses 一下。除此之外也要搞另外一个 pascal unit，里面存交互库的各种接口，让 implementer 和选手程序都 uses 一下。
+
+哦另外 require 文件夹的内容显然不会被下发……如果你想下发一个样例交互库，可以放到 download 文件夹里。
+
+好下面来解释什么是 token……考虑一道典型的交互题，交互库跟选手函数交流得很愉快，最后给了个满分。此时交互库输出了 “AC!!!” 的字样，也可能输出了选手一共调用了几次接口。但是聪明的选手发现，只要自己手动输出一下 “AC!!!” 然后果断退出似乎就能骗过测评系统了娃哈哈。
+
+这是因为选手函数和交互库已经融为一体成为了一个统一的程序，测评系统分辨出谁是谁。这时候，token 就出来拯救世界了。
+
+在 problem.conf 里配置一个奇妙的 token，比如 `token wahaha233`，然后把这个 token 写进交互库的代码里（线上交互库，不是样例交互库）。在交互库准备输出任何东西之前，先输出一下这个 token。当测评系统要给选手判分时，首先判断文件的第一行是不是 token，如果不是，直接零分。这样就避免了奇怪的选手 hack 测评系统了。这里的 token 判定是在调用 checker 之前，测评系统会把 token 去掉之后的选手输出喂给 checker。（所以一道交互题的 token 要好好保护好）
+
+另外另外，记得在 C/C++ 的交互库里给全局变量开 static，意为仅本文件可访问。
+
+#### 意想不到的非传统题
+吼，假如你有一道题不属于上述任何一种题目类型 —— 恭喜你中奖啦！得自己写 judger 啦！
+
+judger 的任务：给你选手提交的文件，把测评结果告诉我。
+
+把 problem.conf 里的 `use_builtin_judger on` 这行去掉，搞一个 judger 放在题目目录下，就好了。
+
+噢对怎么搞这个 judger 呢。。。全自动啦233。。。你需要写个 Makefile……比如
+```makefile
+export INCLUDE_PATH
+CXXFLAGS = -I$(INCLUDE_PATH) -O2
+
+all: chk judger
+
+% : %.cpp
+	$(CXX) $(CXXFLAGS) $< -o $@
+```
+
+什么？你问 judger 应该怎么写？
+
+很抱歉的是这部分我封装得并不是很方便……请 include 一下 uoj_judger.h 来辅助你写 judger……参照 QUINE 这个样题……
+
+说实在的 uoj_judger.h 写得太丑了（不过反正我会用2333）。期待神犇再来造一遍轮子，或者用 python 码个框架（需要解决 python 启动就耗时 40ms 的坑爹问题）
+
+哦对，要使用自己的 judger 的话就只有超级管理员能 “与 SVN 仓库同步” 了。另外无论你的 judger 如何折腾，测评也是有 10 分钟 的时间限制的。

+ * It is strictly recommended to include "testlib.h" before any other include 
+ * in your code. In this case testlib overrides compiler specific "random()".
+ *
+ * If you can't compile your code and compiler outputs something about 
+ * ambiguous call of "random_shuffle", "rand" or "srand" it means that 
+ * you shouldn't use them. Use "shuffle", and "rnd.next()" instead of them
+ * because these calls produce stable result for any C++ compiler. Read 
+ * sample generator sources for clarification.
+ *
+ * Please read the documentation for class "random_t" and use "rnd" instance in
+ * generators. Probably, these sample calls will be usefull for you:
+ *              rnd.next(); rnd.next(100); rnd.next(1, 2); 
+ *              rnd.next(3.14); rnd.next("[a-z]{1,100}").
+ *
+ * Also read about wnext() to generate off-center random distribution.
+ *
+ * See http://code.google.com/p/testlib/ to get latest version or bug tracker.

+ * You can't use pattern for generation if it contains meta-symbol '*'. Also it

+		<p>UOJ不提供头像存储服务。每到一个网站都要上传一个头像挺烦的对不对？UOJ支持Gravatar，请使用Gravatar吧！Gravatar是一个全球的头像存储服务，你的头像将会与你的电子邮箱绑定。在各大网站比如各种Wordpress还有各种OJ比如Vijos、Contest Hunter上，只要你电子邮箱填对了，那么你的头像也就立即能显示了！</p>

+			<h4>6. 交互式类型的题怎么本地测试</h4>
+		</header>
+		<p>唔……好问题。交互式的题一般给了一个头文件要你include进来，以及一个实现接口的源文件grader。好像大家对多个源文件一起编译还不太熟悉。</p>
+		<p>对于C++：<code>g++ -o code grader.cpp code.cpp</code></p>
+		<p>对于C语言：<code>gcc -o code grader.c code.c</code></p>
+		<p>如果你是悲催的电脑盲，实在不会折腾没关系！你可以把grader的文件内容完整地粘贴到你的code的include语句之后，就可以了！</p>
+		<p>什么你是萌萌哒Pascal选手？一般来说都会给个grader，你需要写一个Pascal单元。这个grader会使用你的单元。所以你只需要把源文件取名为单元名 + <code>.pas</code>，然后：</p>
+		<p>对于Pascal语言：<code>fpc grader.pas</code></p>
+		<p>就可以啦！</p>

+ * HTML Purifier is an HTML filter that will take an arbitrary snippet of
+ * HTML and rigorously test, validate and filter it into a version that
+ * is safe for output onto webpages. It achieves this by:
+ *
+ *  -# Lexing (parsing into tokens) the document,
+ *  -# Executing various strategies on the tokens:
+ *      -# Removing all elements not in the whitelist,
+ *      -# Making the tokens well-formed,
+ *      -# Fixing the nesting of the nodes, and
+ *      -# Validating attributes of the nodes; and
+ *  -# Generating HTML from the purified tokens.
+ *
+ * However, most users will only need to interface with the HTMLPurifier
+ * and HTMLPurifier_Config.

+            //  - Dashes rarely occur, but they fairly unproblematic
+            //    for parsing/rendering purposes.
+            //  The above characters cover the majority of Western font
+            //  names.
+            //  - Arbitrary Unicode characters not in ASCII.  Because

+            //    of these codepoints is basically uniform, even for

+            //    show up in non-Western pages and are supported by most
+            //    major browsers, for example: "ＭＳ 明朝" is a
+            //    legitimate font-name
+            //    <http://ja.wikipedia.org/wiki/MS_明朝>.  See
+            //    the CSS3 spec for more examples:
+            //    <http://www.w3.org/TR/2011/WD-css3-fonts-20110324/localizedfamilynames.png>
+            //    You can see live samples of these on the Internet:
+            //    <http://www.google.co.jp/search?q=font-family+ＭＳ+明朝|ゴシック>
+            //    However, most of these fonts have ASCII equivalents:
+            //    for example, 'MS Mincho', and it's considered
+            //    professional to use ASCII font names instead of
+            //    Unicode font names.  Thanks Takeshi Terada for
+            //    providing this information.
+            //  The following characters, to my knowledge, have not been
+            //  used to name font names.
+            //  - Single quote.  While theoretically you might find a
+            //    font name that has a single quote in its name (serving
+            //    as an apostrophe, e.g. Dave's Scribble), I haven't
+            //    been able to find any actual examples of this.
+            //    Internet Explorer's cssText translation (which I
+            //    believe is invoked by innerHTML) normalizes any
+            //    quoting to single quotes, and fails to escape single
+            //    quotes.  (Note that this is not IE's behavior for all
+            //    CSS properties, just some sort of special casing for
+            //    font-family).  So a single quote *cannot* be used
+            //    safely in the font-family context if there will be an
+            //    innerHTML/cssText translation.  Note that Firefox 3.x
+            //    does this too.
+            //  - Double quote.  In IE, these get normalized to
+            //    single-quotes, no matter what the encoding.  (Fun
+            //    fact, in IE8, the 'content' CSS property gained
+            //    support, where they special cased to preserve encoded
+            //    double quotes, but still translate unadorned double
+            //    quotes into single quotes.)  So, because their
+            //    fixpoint behavior is identical to single quotes, they
+            //    cannot be allowed either.  Firefox 3.x displays
+            //    single-quote style behavior.
+            //  - Backslashes are reduced by one (so \\ -> \) every
+            //    iteration, so they cannot be used safely.  This shows
+            //    up in IE7, IE8 and FF3
+            //  - Semicolons, commas and backticks are handled properly.
+            //  - The rest of the ASCII punctuation is handled properly.
+            // We haven't checked what browsers do to unadorned
+            // versions, but this is not important as long as the
+            // browser doesn't /remove/ surrounding quotes (as IE does
+            // for HTML).
+            //
+            // With these results in hand, we conclude that there are
+            // various levels of safety:
+            //  - Paranoid: alphanumeric, spaces and dashes(?)
+            //  - International: Paranoid + non-ASCII Unicode
+            //  - Edgy: Everything except quotes, backslashes
+            //  - NoJS: Standards compliance, e.g. sod IE. Note that
+            //    with some judicious character escaping (since certain
+            //    types of escaping doesn't work) this is theoretically
+            //    OK as long as innerHTML/cssText is not called.
+            // We believe that international is a reasonable default
+            // (that we will implement now), and once we do more
+            // extensive research, we may feel comfortable with dropping
+            // it down to edgy.
+
+            // Edgy: alphanumeric, spaces, dashes, underscores and Unicode.  Use of
+            // str(c)spn assumes that the string was already well formed
+            // Unicode (which of course it is).

+ *
+ *      (CAPTION?, (COL*|COLGROUP*), THEAD?, TFOOT?, TBODY+)

+ *      contains only one table body and no table head or foot sections.
+ *      The TBODY end tag may always be safely omitted.
+ *
+ * So the DTD is kind of wrong.  The validator is, unfortunately, kind
+ * of on crack.
+ *
+ * The definition changed again in XHTML1.1; and in my opinion, this
+ * formulation makes the most sense.
+ *
+ *      caption?, ( col* | colgroup* ), (( thead?, tfoot?, tbody+ ) | ( tr+ ))
+ *
+ * Essentially, we have two modes: thead/tfoot/tbody mode, and tr mode.
+ * If we encounter a thead, tfoot or tbody, we are placed in the former
+ * mode, and we *must* wrap any stray tr segments with a tbody. But if

+Attr.ClassUseCDATA
+TYPE: bool/null
+DEFAULT: null
+VERSION: 4.0.0
+--DESCRIPTION--
+If null, class will auto-detect the doctype and, if matching XHTML 1.1 or
+XHTML 2.0, will use the restrictive NMTOKENS specification of class. Otherwise,
+it will use a relaxed CDATA definition.  If true, the relaxed CDATA definition
+is forced; if false, the NMTOKENS definition is forced.  To get behavior
+of HTML Purifier prior to 4.0.0, set this directive to false.
+
+Some rational behind the auto-detection:
+in previous versions of HTML Purifier, it was assumed that the form of
+class was NMTOKENS, as specified by the XHTML Modularization (representing
+XHTML 1.1 and XHTML 2.0).  The DTDs for HTML 4.01 and XHTML 1.0, however
+specify class as CDATA.  HTML 5 effectively defines it as CDATA, but
+with the additional constraint that each name should be unique (this is not
+explicitly outlined in previous specifications).

+  <strong>Warning:</strong> It is possible for a user to mount an

+  it is not simply enough to limit the range of CSS lengths (using
+  relative lengths with many nesting levels allows for large values
+  to be attained without actually specifying them in the stylesheet),
+  and the flexible nature of selectors makes it difficult to selectively
+  disable lengths on image tags (HTML Purifier, however, does disable
+  CSS width and height in inline styling). There are probably two effective
+  counter measures: an explicit width and height set to auto in all
+  images in your document (unlikely) or the disabling of width and
+  height (somewhat reasonable). Whether or not these measures should be
+  used is left to the reader.

+--DESCRIPTION--
+
+<p>
+    Unique identifier for a custom-built HTML definition. If you edit
+    the raw version of the HTMLDefinition, introducing changes that the
+    configuration object does not reflect, you must specify this variable.
+    If you change your custom edits, you should change this directive, or
+    clear your cache. Example:
+</p>
+<pre>
+$config = HTMLPurifier_Config::createDefault();
+$config->set('HTML', 'DefinitionID', '1');
+$def = $config->getHTMLDefinition();
+$def->addAttribute('a', 'tabindex', 'Number');
+</pre>
+<p>
+    In the above example, the configuration is still at the defaults, but
+    using the advanced API, an extra attribute has been added. The
+    configuration object normally has no way of knowing that this change
+    has taken place, so it needs an extra directive: %HTML.DefinitionID.
+    If someone else attempts to use the default configuration, these two
+    pieces of code will not clobber each other in the cache, since one has
+    an extra directive attached to it.
+</p>
+<p>
+    You <em>must</em> specify a value to this directive to use the
+    advanced API features.

+--DESCRIPTION--
+
+<p>
+    Munges all browsable (usually http, https and ftp)
+    absolute URIs into another URI, usually a URI redirection service.
+    This directive accepts a URI, formatted with a <code>%s</code> where
+    the url-encoded original URI should be inserted (sample:
+    <code>http://www.google.com/url?q=%s</code>).
+</p>
+<p>
+    Uses for this directive:
+</p>
+<ul>
+    <li>
+        Prevent PageRank leaks, while being fairly transparent
+        to users (you may also want to add some client side JavaScript to
+        override the text in the statusbar). <strong>Notice</strong>:
+        Many security experts believe that this form of protection does not deter spam-bots.
+    </li>
+    <li>
+        Redirect users to a splash page telling them they are leaving your
+        website. While this is poor usability practice, it is often mandated
+        in corporate environments.
+    </li>
+</ul>
+<p>
+    Prior to HTML Purifier 3.1.1, this directive also enabled the munging
+    of browsable external resources, which could break things if your redirection
+    script was a splash page or used <code>meta</code> tags. To revert to
+    previous behavior, please use %URI.MungeResources.
+</p>
+<p>
+    You may want to also use %URI.MungeSecretKey along with this directive
+    in order to enforce what URIs your redirector script allows. Open
+    redirector scripts can be a security risk and negatively affect the
+    reputation of your domain name.
+</p>
+<p>
+    Starting with HTML Purifier 3.1.1, there is also these substitutions:

+    <tbody>
+        <tr>
+            <td>%r</td>
+            <td>1 - The URI embeds a resource<br />(blank) - The URI is merely a link</td>
+            <td></td>
+        </tr>
+        <tr>
+            <td>%n</td>
+            <td>The name of the tag this URI came from</td>

+    </tbody>

+    Admittedly, these letters are somewhat arbitrary; the only stipulation
+    was that they couldn't be a through f. r is for resource (I would have preferred
+    e, but you take what you can get), n is for name, m
+    was picked because it came after n (and I couldn't use a), p is for

+ * Forgivingly lexes HTML (SGML-style) markup into tokens.
+ *
+ * A lexer parses a string of SGML-style markup and converts them into
+ * corresponding tokens.  It doesn't check for well-formedness, although its
+ * internal mechanism may make this automatic (such as the case of
+ * HTMLPurifier_Lexer_DOMLex).  There are several implementations to choose
+ * from.
+ *
+ * A lexer is HTML-oriented: it might work with XML, but it's not
+ * recommended, as we adhere to a subset of the specification for optimization
+ * reasons. This might change in the future. Also, most tokenizers are not
+ * expected to handle DTDs or PIs.
+ *
+ * This class should not be directly instantiated, but you may use create() to
+ * retrieve a default copy of the lexer.  Being a supertype, this class
+ * does not actually define any implementation, but offers commonly used
+ * convenience functions for subclasses.
+ *
+ * @note The unit tests will instantiate this class for testing purposes, as
+ *       many of the utility functions require a class to be instantiated.
+ *       This means that, even though this class is not runnable, it will
+ *       not be declared abstract.
+ *
+ * @par
+ *
+ * @note
+ * We use tokens rather than create a DOM representation because DOM would:
+ *
+ * @par
+ *  -# Require more processing and memory to create,
+ *  -# Is not streamable, and
+ *  -# Has the entire document structure (html and body not needed).
+ *
+ * @par
+ * However, DOM is helpful in that it makes it easy to move around nodes
+ * without a lot of lookaheads to see when a tag is closed. This is a
+ * limitation of the token system and some workarounds would be nice.

+ * Parser that uses PHP 5's DOM extension (part of the core).
+ *
+ * In PHP 5, the DOM XML extension was revamped into DOM and added to the core.
+ * It gives us a forgiving HTML parser, which we use to transform the HTML
+ * into a DOM, and then into the tokens.  It is blazingly fast (for large
+ * documents, it performs twenty times faster than
+ * HTMLPurifier_Lexer_DirectLex,and is the default choice for PHP 5.
+ *
+ * @note Any empty elements will have empty tokens associated with them, even if
+ * this is prohibited by the spec. This is cannot be fixed until the spec
+ * comes into play.
+ *
+ * @note PHP's DOM extension does not actually parse any entities, we use
+ *       our own function to do that.
+ *
+ * @warning DOM tends to drop whitespace, which may wreak havoc on indenting.
+ *          If this is a huge problem, due to the fact that HTML is hand
+ *          edited and you are unable to get a parser cache that caches the
+ *          the output of HTML Purifier while keeping the original HTML lying
+ *          around, you may want to run Tidy on the resulting output or use
+ *          HTMLPurifier_DirectLex

+/**
+ * Chainable filters for custom URI processing.
+ *
+ * These filters can perform custom actions on a URI filter object,
+ * including transformation or blacklisting.  A filter named Foo
+ * must have a corresponding configuration directive %URI.Foo,
+ * unless always_load is specified to be true.
+ *
+ * The following contexts may be available while URIFilters are being
+ * processed:
+ *
+ *      - EmbeddedURI: true if URI is an embedded resource that will
+ *        be loaded automatically on page load
+ *      - CurrentToken: a reference to the token that is currently
+ *        being processed
+ *      - CurrentAttr: the name of the attribute that is currently being
+ *        processed
+ *      - CurrentCSSProperty: the name of the CSS property that is
+ *        currently being processed (if applicable)
+ *
+ * @warning This filter is called before scheme object validation occurs.
+ *          Make sure, if you require a specific scheme object, you
+ *          you check that it exists. This allows filters to convert
+ *          proprietary URI schemes into regular ones.

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990
+  Ty Coon, President of Vice
+
+That's all there is to it!

+# PHPMailer - A full-featured email creation and transfer class for PHP
+
+Build status: [![Build Status](https://travis-ci.org/PHPMailer/PHPMailer.svg)](https://travis-ci.org/PHPMailer/PHPMailer)
+[![Scrutinizer Quality Score](https://scrutinizer-ci.com/g/PHPMailer/PHPMailer/badges/quality-score.png?s=3758e21d279becdf847a557a56a3ed16dfec9d5d)](https://scrutinizer-ci.com/g/PHPMailer/PHPMailer/)
+[![Code Coverage](https://scrutinizer-ci.com/g/PHPMailer/PHPMailer/badges/coverage.png?s=3fe6ca5fe8cd2cdf96285756e42932f7ca256962)](https://scrutinizer-ci.com/g/PHPMailer/PHPMailer/)
+
+## Class Features
+
+- Probably the world's most popular code for sending email from PHP!
+- Used by many open-source projects: Drupal, SugarCRM, Yii, Joomla! and many more
+- Integrated SMTP support - send without a local mail server
+- Send emails with multiple TOs, CCs, BCCs and REPLY-TOs
+- Multipart/alternative emails for mail clients that do not read HTML email
+- Support for UTF-8 content and 8bit, base64, binary, and quoted-printable encodings
+- SMTP authentication with LOGIN, PLAIN, NTLM and CRAM-MD5 mechanisms over SSL and TLS transports
+- Native language support
+- DKIM and S/MIME signing support
+- Compatible with PHP 5.0 and later
+- Much more!
+
+## Why you might need it
+
+Many PHP developers utilize email in their code. The only PHP function that supports this is the mail() function. However, it does not provide any assistance for making use of popular features such as HTML-based emails and attachments.
+
+Formatting email correctly is surprisingly difficult. There are myriad overlapping RFCs, requiring tight adherence to horribly complicated formatting and encoding rules - the vast majority of code that you'll find online that uses the mail() function directly is just plain wrong!
+*Please* don't be tempted to do it yourself - if you don't use PHPMailer, there are many other excellent libraries that you should look at before rolling your own - try SwiftMailer, Zend_Mail, eZcomponents etc.
+
+The PHP mail() function usually sends via a local mail server, typically fronted by a `sendmail` binary on Linux, BSD and OS X platforms, however, Windows usually doesn't include a local mail server; PHPMailer's integrated SMTP implementation allows email sending on Windows platforms without a local mail server.
+
+## License
+
+This software is licenced under the [LGPL 2.1](http://www.gnu.org/licenses/lgpl-2.1.html). Please read LICENSE for information on the
+software availability and distribution.
+
+## Installation & loading
+
+PHPMailer is available via [Composer/Packagist](https://packagist.org/packages/phpmailer/phpmailer). Alternatively, just copy the contents of the PHPMailer folder into somewhere that's in your PHP `include_path` setting. If you don't speak git or just want a tarball, click the 'zip' button at the top of the page in GitHub.
+
+PHPMailer provides an SPL-compatible autoloader, and that is the preferred way of loading the library - just `require '/path/to/PHPMailerAutoload.php';` and everything should work. The autoloader does not throw errors if it can't find classes so it prepends itself to the SPL list, allowing your own (or your framework's) autoloader to catch errors. SPL autoloading was introduced in PHP 5.1.0, so if you are using a version older than that you will need to require/include each class manually.
+PHPMailer does *not* declare a namespace because namespaces were only introduced in PHP 5.3.
+
+### Minimal installation
+
+While installing the entire package manually or with composer is simple, convenient and reliable, you may want to include only vital files in your project. At the very least you will need [class.phpmailer.php](class.phpmailer.php). If you're using SMTP, you'll need [class.smtp.php](class.smtp.php), and if you're using POP-before SMTP, you'll need [class.pop3.php](class.pop3.php). For all of these, we recommend you use [the autoloader](PHPMailerAutoload.php) too as otherwise you will either have to `require` all classes manually or use some other autoloader. You can skip the [language](language/) folder if you're not showing errors to users and can make do with English-only errors. You may need the additional classes in the [extras](extras/) folder if you are using those features, including NTLM authentication, advanced HTML-to-text conversion and ics generation.
+
+## A Simple Example
+
+```php
+<?php
+require 'PHPMailerAutoload.php';
+
+$mail = new PHPMailer;
+
+//$mail->SMTPDebug = 3;                               // Enable verbose debug output
+
+$mail->isSMTP();                                      // Set mailer to use SMTP
+$mail->Host = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup SMTP servers
+$mail->SMTPAuth = true;                               // Enable SMTP authentication
+$mail->Username = 'user@example.com';                 // SMTP username
+$mail->Password = 'secret';                           // SMTP password
+$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
+$mail->Port = 587;                                    // TCP port to connect to
+
+$mail->From = 'from@example.com';
+$mail->FromName = 'Mailer';
+$mail->addAddress('joe@example.net', 'Joe User');     // Add a recipient
+$mail->addAddress('ellen@example.com');               // Name is optional
+$mail->addReplyTo('info@example.com', 'Information');
+$mail->addCC('cc@example.com');
+$mail->addBCC('bcc@example.com');
+
+$mail->WordWrap = 50;                                 // Set word wrap to 50 characters
+$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
+$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
+$mail->isHTML(true);                                  // Set email format to HTML
+
+$mail->Subject = 'Here is the subject';
+$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
+$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
+
+if(!$mail->send()) {
+    echo 'Message could not be sent.';
+    echo 'Mailer Error: ' . $mail->ErrorInfo;
+} else {
+    echo 'Message has been sent';
+}
+```
+
+You'll find plenty more to play with in the [examples](examples/) folder.
+
+That's it. You should now be ready to use PHPMailer!
+
+## Localization
+PHPMailer defaults to English, but in the [language](language/) folder you'll find numerous (39 at the time of writing) translations for PHPMailer error messages that you may encounter. Their filenames contain [ISO 639-1](http://en.wikipedia.org/wiki/ISO_639-1) language code for the translations, for example `fr` for French. To specify a language, you need to tell PHPMailer which one to use, like this:
+
+```php
+// To load the French version
+$mail->setLanguage('fr', '/optional/path/to/language/directory/');
+```
+
+We welcome corrections and new languages - if you're looking for corrections to do, run the [phpmailerLangTest.php](test/phpmailerLangTest.php) script in the tests folder and it will show any missing translations.
+
+## Documentation
+
+Generated documentation is [available online](http://phpmailer.github.io/PHPMailer/).
+
+You'll find some basic user-level docs in the [docs](docs/) folder, and you can generate complete API-level documentation using the [generatedocs.sh](docs/generatedocs.sh) shell script in the docs folder, though you'll need to install [PHPDocumentor](http://www.phpdoc.org) first. You may find [the unit tests](test/phpmailerTest.php) a good source of how to do various operations such as encryption.
+
+## Tests
+
+There is a PHPUnit test script in the [test](test/) folder.
+
+Build status: [![Build Status](https://travis-ci.org/PHPMailer/PHPMailer.svg)](https://travis-ci.org/PHPMailer/PHPMailer)
+
+If this isn't passing, is there something you can do to help?

+* Temporary fix for missing attachments
+
+## Version 5.0.0 (April 02, 2009)
+With the release of this version, we are initiating a new version numbering
+system to differentiate from the PHP4 version of PHPMailer.
+Most notable in this release is fully object oriented code.
+
+### class.smtp.php:
+* Refactored class.smtp.php to support new exception handling
+* code size reduced from 29.2 Kb to 25.6 Kb
+* Removed unnecessary functions from class.smtp.php:
+  - public function Expand($name) {
+  - public function Help($keyword="") {
+  - public function Noop() {
+  - public function Send($from) {
+  - public function SendOrMail($from) {
+  - public function Verify($name) {
+
+###  class.phpmailer.php:
+* Refactored class.phpmailer.php with new exception handling
+* Changed processing functionality of Sendmail and Qmail so they cannot be
+  inadvertently used
+* removed getFile() function, just became a simple wrapper for
+  file_get_contents()
+* added check for PHP version (will gracefully exit if not at least PHP 5.0)
+* enhanced code to check if an attachment source is the same as an embedded or
+  inline graphic source to eliminate duplicate attachments
+
+### New /test_script
+We have written a test script you can use to test the script as part of your
+installation. Once you press submit, the test script will send a multi-mime
+email with either the message you type in or an HTML email with an inline
+graphic. Two attachments are included in the email (one of the attachments
+is also the inline graphic so you can see that only one copy of the graphic
+is sent in the email). The test script will also display the functional
+script that you can copy/paste to your editor to duplicate the functionality.
+
+### New examples
+All new examples in both basic and advanced modes. Advanced examples show
+   Exception handling.
+
+### PHPDocumentator (phpdocs) documentation for PHPMailer version 5.0.0
+All new documentation
+
+## Version 2.3 (November 06, 2008)
+* added Arabic language (many thanks to Bahjat Al Mostafa)
+* removed English language from language files and made it a default within
+  class.phpmailer.php - if no language is found, it will default to use
+  the english language translation
+* fixed public/private declarations
+* corrected line 1728, $basedir to $directory
+* added $sign_cert_file to avoid improper duplicate use of $sign_key_file
+* corrected $this->Hello on line 612 to $this->Helo
+* changed default of $LE to "\r\n" to comply with RFC 2822. Can be set by the user
+  if default is not acceptable
+* removed trim() from return results in EncodeQP
+* /test and three files it contained are removed from version 2.3
+* fixed phpunit.php for compliance with PHP5
+* changed $this->AltBody = $textMsg; to $this->AltBody = html_entity_decode($textMsg);
+* We have removed the /phpdoc from the downloads. All documentation is now on
+  the http://phpmailer.codeworxtech.com website.
+
+## Version 2.2.1 () July 19 2008
+* fixed line 1092 in class.smtp.php (my apologies, error on my part)
+
+## Version 2.2 () July 15 2008
+* Fixed redirect issue (display of UTF-8 in thank you redirect)
+* fixed error in getResponse function declaration (class.pop3.php)
+* PHPMailer now PHP6 compliant
+* fixed line 1092 in class.smtp.php (endless loop from missing = sign)
+
+## Version 2.1 (Wed, June 04 2008)
+NOTE: WE HAVE A NEW LANGUAGE VARIABLE FOR DIGITALLY SIGNED S/MIME EMAILS. IF YOU CAN HELP WITH LANGUAGES OTHER THAN ENGLISH AND SPANISH, IT WOULD BE APPRECIATED.
+
+* added S/MIME functionality (ability to digitally sign emails)
+  BIG THANKS TO "sergiocambra" for posting this patch back in November 2007.
+  The "Signed Emails" functionality adds the Sign method to pass the private key
+  filename and the password to read it, and then email will be sent with
+  content-type multipart/signed and with the digital signature attached.
+* fully compatible with E_STRICT error level
+  - Please note:
+    In about half the test environments this development version was subjected
+    to, an error was thrown for the date() functions used (line 1565 and 1569).
+    This is NOT a PHPMailer error, it is the result of an incorrectly configured
+    PHP5 installation. The fix is to modify your 'php.ini' file and include the
+    date.timezone = Etc/UTC (or your own zone)
+    directive, to your own server timezone
+  - If you do get this error, and are unable to access your php.ini file:
+    In your PHP script, add
+    `date_default_timezone_set('Etc/UTC');`
+  - do not try to use
+    `$myVar = date_default_timezone_get();`
+    as a test, it will throw an error.
+* added ability to define path (mainly for embedded images)
+  function `MsgHTML($message,$basedir='')` ... where:
+  `$basedir` is the fully qualified path
+* fixed `MsgHTML()` function:
+  - Embedded Images where images are specified by `<protocol>://` will not be altered or embedded
+* fixed the return value of SMTP exit code ( pclose )
+* addressed issue of multibyte characters in subject line and truncating
+* added ability to have user specified Message ID
+  (default is still that PHPMailer create a unique Message ID)
+* corrected unidentified message type to 'application/octet-stream'
+* fixed chunk_split() multibyte issue (thanks to Colin Brown, et al).
+* added check for added attachments
+* enhanced conversion of HTML to text in MsgHTML (thanks to "brunny")
+
+## Version 2.1.0beta2 (Sun, Dec 02 2007)
+* implemented updated EncodeQP (thanks to coolbru, aka Marcus Bointon)
+* finished all testing, all known bugs corrected, enhancements tested
+
+Note: will NOT work with PHP4.

+NEW CALLBACK FUNCTION:
+======================
+
+We have had requests for a method to process the results of sending emails 
+through PHPMailer. In this new release, we have implemented a callback
+function that passes the results of each email sent (to, cc, and/or bcc). 
+We have provided an example that echos the results back to the screen. The
+callback function can be used for any purpose. With minor modifications, the
+callback function can be used to create CSV logs, post results to databases,
+etc.
+
+Please review the test.php script for the example.
+
+It's pretty straight forward.
+
+Enjoy!

+CREATE DKIM KEYS and DNS Resource Record:
+=========================================
+
+To create DomainKeys Identified Mail keys, visit:
+http://dkim.worxware.com/
+... read the information, fill in the form, and download the ZIP file 
+containing the public key, private key, DNS Resource Record and instructions
+to add to your DNS Zone Record, and the PHPMailer code to enable DKIM
+digital signing.
+
+/*** PROTECT YOUR PRIVATE & PUBLIC KEYS ***/
+
+You need to protect your DKIM private and public keys from being viewed or
+accessed. Add protection to your .htaccess file as in this example:
+
+# secure htkeyprivate file
+<Files .htkeyprivate>
+  order allow,deny
+  deny from all
+</Files>
+
+# secure htkeypublic file
+<Files .htkeypublic>
+  order allow,deny
+  deny from all
+</Files>
+
+(the actual .htaccess additions are in the ZIP file sent back to you from 
+http://dkim.worxware.com/ 
+
+A few notes on using DomainKey Identified Mail (DKIM):
+
+You do not need to use PHPMailer to DKIM sign  emails IF:
+- you enable DomainKey support and add the DNS resource record
+- you use your outbound mail server
+
+If you are a third-party emailer that works on behalf of domain owners to
+send their emails from your own server:
+- you absolutely have to DKIM sign outbound emails
+- the domain owner has to add the DNS resource record to match the 
+  private key, public key, selector, identity, and domain that you create
+- use caution with the "selector" ... at least one "selector" will already
+  exist in the DNS Zone Record of the domain at the domain owner's server
+  you need to ensure that the "selector" you use is unique
+Note: since the IP address will not match the domain owner's DNS Zone record
+you can be certain that email providers that validate based on DomainKey will
+check the domain owner's DNS Zone record for your DNS resource record. Before
+sending out emails on behalf of domain owners, ensure they have entered the 
+DNS resource record you provided them.
+
+Enjoy!
+Andy
+
+PS. if you need additional information about DKIM, please see:

+If you are having problems connecting or sending emails through your SMTP server, the SMTP class can provide more information about the processing/errors taking place.
+Use the debug functionality of the class to see what's going on in your connections. To do that, set the debug level in your script. For example:
+
+$mail->SMTPDebug = 1;
+$mail->isSMTP();  // telling the class to use SMTP
+$mail->SMTPAuth   = true;                // enable SMTP authentication

+$mail->Username   = "name@yourhost.com"; // SMTP account username
+$mail->Password   = "your password";     // SMTP account password
+
+Notes on this:
+$mail->SMTPDebug = 0; ... will disable debugging (you can also leave this out completely, 0 is the default)
+$mail->SMTPDebug = 1; ... will echo errors and server responses
+$mail->SMTPDebug = 2; ... will echo errors, server responses and client messages
+
+And finally, don't forget to disable debugging before going into production.

+
+<h2>Examples using PHPMailer</h2>
+
+<h3>1. Advanced Example</h3>
+<p>
+
+This demonstrates sending multiple email messages with binary attachments
+from a MySQL database using multipart/alternative messages.<p>
+
+<pre>
+require 'PHPMailerAutoload.php';
+
+$mail = new PHPMailer();
+
+$mail->From     = 'list@example.com';
+$mail->FromName = 'List manager';
+$mail->Host     = 'smtp1.example.com;smtp2.example.com';
+$mail->Mailer   = 'smtp';
+
+@mysqli_connect('localhost','root','password');
+@mysqli_select_db("my_company");
+$query = "SELECT full_name, email, photo FROM employee";
+$result = @mysqli_query($query);
+
+while ($row = mysqli_fetch_assoc($result))
+{
+    // HTML body
+    $body  = "Hello &lt;font size=\"4\"&gt;" . $row['full_name'] . "&lt;/font&gt;, &lt;p&gt;";
+    $body .= "&lt;i&gt;Your&lt;/i&gt; personal photograph to this message.&lt;p&gt;";
+    $body .= "Sincerely, &lt;br&gt;";
+    $body .= "phpmailer List manager";
+
+    // Plain text body (for mail clients that cannot read HTML)
+    $text_body  = 'Hello ' . $row['full_name'] . ", \n\n";
+    $text_body .= "Your personal photograph to this message.\n\n";
+    $text_body .= "Sincerely, \n";
+    $text_body .= 'phpmailer List manager';
+
+    $mail->Body    = $body;
+    $mail->AltBody = $text_body;
+    $mail->addAddress($row['email'], $row['full_name']);
+    $mail->addStringAttachment($row['photo'], 'YourPhoto.jpg');
+
+    if(!$mail->send())
+        echo "There has been a mail error sending to " . $row['email'] . "&lt;br&gt;";
+
+    // Clear all addresses and attachments for next loop
+    $mail->clearAddresses();
+    $mail->clearAttachments();
+}
+</pre>

+
+<h3>2. Extending PHPMailer</h3>
+<p>
+
+Extending classes with inheritance is one of the most
+powerful features of object-oriented programming. It allows you to make changes to the
+original class for your own personal use without hacking the original
+classes, and it's very easy to do:
+
+<p>
+Here's a class that extends the phpmailer class and sets the defaults
+for the particular site:<br>

+<h2>PHPMailer FAQ</h2>
+<ul>
+    <li><strong>Q: I am concerned that using include files will take up too much
+    processing time on my computer. How can I make it run faster?</strong><br>
+    <strong>A:</strong> PHP by itself is fairly fast, but it recompiles scripts every time they are run, which takes up valuable
+    computer resources. You can bypass this by using an opcode cache which compiles
+    PHP code and store it in memory to reduce overhead immensely. <a href="http://www.php.net/apc/">APC
+    (Alternative PHP Cache)</a> is a free opcode cache extension in the PECL library.</li>
+    <li><strong>Q: Which mailer gives me the best performance?</strong><br>
+    <strong>A:</strong> On a single machine the <strong>sendmail (or Qmail)</strong> is fastest overall.
+    Next fastest is mail() to give you the best performance. Both do not have the overhead of SMTP.
+    If you do not have a local mail server (as is typical on Windows), SMTP is your only option.</li>
+    <li><strong>Q: When I try to attach a file with on my server I get a
+    "Could not find {file} on filesystem error". Why is this?</strong><br>
+    <strong>A:</strong> If you are using a Unix machine this is probably because the user
+    running your web server does not have read access to the directory in question. If you are using Windows,
+    then the problem is probably that you have used single backslashes to denote directories (\).
+    A single backslash has a special meaning to PHP so these are not
+    valid. Instead use double backslashes ("\\") or a single forward
+    slash ("/").</li>

+This is built for PHP Mailer 1.72 and was not tested with any previous version. It was developed under PHP 4.3.11 (E_ALL). It works under PHP 5 and 5.1 with E_ALL, but not in Strict mode due to var deprecation (but then neither does PHP Mailer either!). It follows the RFC 1939 standard explicitly and is fully commented.
+
+With that noted, here is how to implement it:
+
+I didn't want to modify the PHP Mailer classes at all, so you will have to include/require this class along with the base one. It can sit quite happily in the phpmailer directory.
+
+When you need it, create your POP3 object
+
+Right before I invoke PHP Mailer I activate the POP3 authorisation. POP3 before SMTP is a process whereby you login to your web hosts POP3 mail server BEFORE sending out any emails via SMTP. The POP3 logon 'verifies' your ability to send email by SMTP, which typically otherwise blocks you. On my web host (Pair Networks) a single POP3 logon is enough to 'verify' you for 90 minutes. Here is some sample PHP code that activates the POP3 logon and then sends an email via PHP Mailer:
+
+<?php
+$pop->authorise('pop3.example.com', 110, 30, 'mailer', 'password', 1);
+$mail = new PHPMailer(); $mail->SMTPDebug = 2; $mail->isSMTP();
+$mail->isHTML(false); $mail->Host = 'relay.example.com';
+$mail->From = 'mailer@example.com';
+$mail->FromName = 'Example Mailer';
+$mail->Subject = 'My subject';
+$mail->Body = 'Hello world';
+$mail->addAddress('rich@corephp.co.uk', 'Richard Davey');
+if (!$mail->send()) {
+    echo $mail->ErrorInfo;
+}
+?>
+
+The PHP Mailer parts of this code should be obvious to anyone who has used PHP Mailer before. One thing to note - you almost certainly will not need to use SMTP Authentication *and* POP3 before SMTP together. The Authorisation method is a proxy method to all of the others within that class. There are connect, Logon and disconnect methods available, but I wrapped them in the single Authorisation one to make things easier.
+The Parameters
+
+The authorise parameters are as follows:
+
+$pop->authorise('pop3.example.com', 110, 30, 'mailer', 'password', 1);
+
+   1. pop3.example.com - The POP3 Mail Server Name (hostname or IP address)
+   2. 110 - The POP3 Port on which to connect (default is usually 110, but check with your host)
+   3. 30 - A connection time-out value (in seconds)
+   4. mailer - The POP3 Username required to logon
+   5. password - The POP3 Password required to logon
+   6. 1 - The class debug level (0 = off, 1+ = debug output is echoed to the browser)
+
+Final Comments + the Download
+
+1) This class does not support APOP connections. This is only because I did not have an APOP server to test with, but if you'd like to see that added just contact me.
+
+2) Opening and closing lots of POP3 connections can be quite a resource/network drain. If you need to send a whole batch of emails then just perform the authentication once at the start, and then loop through your mail sending script. Providing this process doesn't take longer than the verification period lasts on your POP3 server, you should be fine. With my host that period is 90 minutes, i.e. plenty of time.
+
+3) If you have heavy requirements for this script (i.e. send a LOT of email on a frequent basis) then I would advise seeking out an alternative sending method (direct SMTP ideally). If this isn't possible then you could modify this class so the 'last authorised' date is recorded somewhere (MySQL, Flat file, etc) meaning you only open a new connection if the old one has expired, saving you precious overhead.
+
+4) There are lots of other POP3 classes for PHP available. However most of them implement the full POP3 command set, where-as this one is purely for authentication, and much lighter as a result. However using any of the other POP3 classes to just logon to your server would have the same net result. At the end of the day, use whatever method you feel most comfortable with.
+Download
+
+My thanks to Chris Ryan for the inspiration (even if indirectly, via his SMTP class)

+		   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions. 
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version. 
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+<h1>PHPMailer code examples<a href="https://github.com/PHPMailer/PHPMailer"><img src="images/phpmailer.png" style="float:right; border:0;" alt="PHPMailer logo"></a></h1>
+<p>This folder contains a collection of examples of using <a href="https://github.com/PHPMailer/PHPMailer">PHPMailer</a>.</p>
+<h2>About testing email sending</h2>
+<p>When working on email sending code you'll find yourself worrying about what might happen if all these test emails got sent to your mailing list. The solution is to use a fake mail server, one that acts just like the real thing, but just doesn't actually send anything out. Some offer web interfaces, feedback, logging, the ability to return specific error codes, all things that are useful for testing error handling, authentication etc. Here's a selection of mail testing tools you might like to try:</p>
+<ul>
+  <li><a href="https://github.com/isotoma/FakeEmail">FakeEmail</a>, a Python-based fake mail server with a web interface.</li>
+  <li><a href="http://www.postfix.org/smtp-sink.1.html">smtp-sink</a>, part of the Postfix mail server, so you probably already have this installed. This is used in the Travis-CI configuration to run PHPMailer's unit tests.</li>
+  <li><a href="https://github.com/Nilhcem/FakeSMTP">FakeSMTP</a>, a Java desktop app with the ability to show an SMTP log and save messages to a folder.</li>
+  <li><a href="http://smtp4dev.codeplex.com">smtp4dev</a>, a dummy SMTP server for Windows.</li>
+  <li><a href="https://github.com/PHPMailer/PHPMailer/blob/master/test/fakesendmail.sh">fakesendmail.sh</a>, part of PHPMailer's test setup, this is a shell script that emulates sendmail for testing 'mail' or 'sendmail' methods in PHPMailer.</li>
+  <li><a href="http://tools.ietf.org/tools/msglint/">msglint</a>, not a mail server, the IETF's MIME structure analyser checks the formatting of your messages.</li>
+</ul>
+<div style="padding: 8px; color: #333333; background-color: #dc8b92">
+<h2>Security note</h2>
+<p>Before running these examples you'll need to rename them with '.php' extensions. They are supplied as '.phps' files which will usually be displayed with syntax highlighting by PHP instead of running them. This prevents potential security issues with running potential spam-gateway code if you happen to deploy these code examples on a live site - <em>please don't do that!</em> Similarly, don't leave your passwords in these files as they will be visible to the world!</p>
+</div>
+<h2><a href="code_generator.phps">code_generator.phps</a></h2>
+<p>This script is a simple code generator - fill in the form and hit submit, and it will use when you entered to email you a message, and will also generate PHP code using your settings that you can copy and paste to use in your own apps. If you need to get going quickly, this is probably the best place to start.</p>
+<h2><a href="mail.phps">mail.phps</a></h2>
+<p>This script is a basic example which creates an email message from an external HTML file, creates a plain text body, sets various addresses, adds an attachment and sends the message. It uses PHP's built-in mail() function which is the simplest to use, but relies on the presence of a local mail server, something which is not usually available on Windows. If you find yourself in that sitution, either install a local mail server, or use a remote one and send using SMTP instead.</p>
+<h2><a href="exceptions.phps">exceptions.phps</a></h2>
+<p>The same as the mail example, but shows how to use PHPMailer's optional exceptions for error handling.</p>
+<h2><a href="smtp.phps">smtp.phps</a></h2>
+<p>A simple example sending using SMTP with authentication.</p>
+<h2><a href="smtp_no_auth.phps">smtp_no_auth.phps</a></h2>
+<p>A simple example sending using SMTP without authentication.</p>
+<h2><a href="sendmail.phps">sendmail.phps</a></h2>
+<p>A simple example using sendmail. Sendmail is a program (usually found on Linux/BSD, OS X and other UNIX-alikes) that can be used to submit messages to a local mail server without a lengthy SMTP conversation. It's probably the fastest sending mechanism, but lacks some error reporting features. There are sendmail emulators for most popular mail servers including postfix, qmail, exim etc.</p>
+<h2><a href="gmail.phps">gmail.phps</a></h2>
+<p>Submitting email via Google's Gmail service is a popular use of PHPMailer. It's much the same as normal SMTP sending, just with some specific settings, namely using TLS encryption, authentication is enabled, and it connects to the SMTP submission port 587 on the smtp.gmail.com host. This example does all that.</p>
+<h2><a href="pop_before_smtp.phps">pop_before_smtp.phps</a></h2>
+<p>Before effective SMTP authentication mechanisms were available, it was common for ISPs to use POP-before-SMTP authentication. As it implies, you authenticate using the POP3 protocol (an older protocol now mostly replaced by the far superior IMAP), and then the SMTP server will allow send access from your IP address for a short while, usually 5-15 minutes. PHPMailer includes a POP3 protocol client, so it can carry out this sequence - it's just like a normal SMTP conversation (without authentication), but connects via POP first.</p>
+<h2><a href="mailing_list.phps">mailing_list.phps</a></h2>
+<p>This is a somewhat naïve example of sending similar emails to a list of different addresses. It sets up a PHPMailer instance using SMTP, then connects to a MySQL database to retrieve a list of recipients. The code loops over this list, sending email to each person using their info and marks them as sent in the database. It makes use of SMTP keepalive which saves reconnecting and re-authenticating between each message.</p>
+<hr>
+<p>Most of these examples use the 'example.com' domain. This domain is reserved by IANA for illustrative purposes, as documented in <a href="http://tools.ietf.org/html/rfc2606">RFC 2606</a>. Don't use made-up domains like 'mydomain.com' or 'somedomain.com' in examples as someone, somewhere, probably owns them!</p>

+#PHPMailer Extras
+
+These classes provide optional additional functions to PHPMailer.
+
+These are not loaded by the PHPMailer autoloader, so in some cases you may need to `require` them yourself before using them.
+
+##HTML2Text
+
+This class was written by Jon Abernathy and provides a simple conversion of HTML to plain-text, while attempting to preserve some aspects of the formatting. It is used in PHPMailer if you set the `advanced` parameter to `true` in either the `msgHTML()` or `html2text` methods of PHPMailer.
+
+##EasyPeasyICS
+
+This class was originally written by Manuel Reinhard and provides a simple means of generating ICS/vCal files that are used in sending calendar events. PHPMailer does not use it diorectly, but you can use it to generate content appropriate for placing in the `Ical` property of PHPMailer. The PHPMailer project is now its official home as Manuel has given permission for that and is no longer maintaining it himself.
+
+##htmlfilter
+
+This class by Konstantin Riabitsev and Jim Jagielski implements HTML filtering to remove potentially malicious tags, such as `<script>` or `onclick=` attributes that can result in XSS attacks. This is a simple filter and is not as comprehensive as [HTMLawed](http://www.bioinformatics.org/phplabware/internal_utilities/htmLawed/) or [HTMLPurifier](http://htmlpurifier.org), but it's easier to use and considerably better than nothing! PHPMailer does not use it directly, but you may want to apply it to user-supplied HTML before using it as a message body.
+
+##NTLM_SASL_client
+
+This class by Manuel Lemos (bundled with permission) adds the ability to authenticate with Microsoft Windows mail servers that use NTLM-based authentication. It is used by PHPMailer if you send via SMTP and set the `AuthType` property to `NTLM`; you will also need to use the `Realm` and `Workstation` properties. The original source is [here](http://www.phpclasses.org/browse/file/7495.html).

+## Dependencies
+
+Themes are written using Sass to keep things modular and reduce the need for repeated selectors across files. Make sure that you have the reveal.js development environment including the Grunt dependencies installed before proceding: https://github.com/hakimel/reveal.js#full-setup
+
+You also need to install Ruby and then Sass (with `gem install sass`).
+
+## Creating a Theme
+
+To create your own theme, start by duplicating any ```.scss``` file in [/css/theme/source](https://github.com/hakimel/reveal.js/blob/master/css/theme/source) and adding it to the compilation list in the [Gruntfile](https://github.com/hakimel/reveal.js/blob/master/Gruntfile.js).
+
+Each theme file does four things in the following order:
+
+1. **Include [/css/theme/template/mixins.scss](https://github.com/hakimel/reveal.js/blob/master/css/theme/template/mixins.scss)**
+Shared utility functions.
+
+2. **Include [/css/theme/template/settings.scss](https://github.com/hakimel/reveal.js/blob/master/css/theme/template/settings.scss)**
+Declares a set of custom variables that the template file (step 4) expects. Can be overridden in step 3.
+
+3. **Override**
+This is where you override the default theme. Either by specifying variables (see [settings.scss](https://github.com/hakimel/reveal.js/blob/master/css/theme/template/settings.scss) for reference) or by adding full selectors with hardcoded styles.
+
+4. **Include [/css/theme/template/theme.scss](https://github.com/hakimel/reveal.js/blob/master/css/theme/template/theme.scss)**
+The template theme file which will generate final CSS output based on the currently defined variables.
+
+When you are done, run `grunt css-themes` to compile the Sass file to CSS and you are ready to use your new theme.

+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+—————————————————————————————-
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+“Font Software” refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation.
+
+“Reserved Font Name” refers to any names specified as such after the copyright statement(s).
+
+“Original Version” refers to the collection of Font Software components as distributed by the Copyright Holder(s).
+
+“Modified Version” refers to any derivative made by adding to, deleting, or substituting—in part or in whole—any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment.
+

These can be included either as stand-alone text files, human-readable headers or in the appropriate machine-readable metadata fields within text or binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be used to promote, endorse or advertise any Modified Version, except to acknowledge the contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written permission.
+
+5) The Font Software, modified or unmodified, in part or in whole, must be distributed entirely under this license, and must not be distributed under any other license. The requirement for fonts to remain under this license does not apply to any document created using the Font Software.

+CKEditor WebSpellChecker Plugin
+===============================
+
+This plugin brings Web Spell Checker (WSC) into CKEditor.
+
+WSC is "installation-less", using the web-services of [WebSpellChecker.net](http://www.webspellchecker.net/). It's an out of the box solution.
+
+Installation
+------------
+
+1. Clone/copy this repository contents in a new "plugins/wsc" folder in your CKEditor installation.
+2. Enable the "wsc" plugin in the CKEditor configuration file (config.js):
+
+        config.extraPlugins = 'wsc';
+
+That's all. WSC will appear on the editor toolbar and will be ready to use.

+- **reset.css**: the file defines the basis of style resets among all editor UI spaces,
+- **preset.css**: the file defines the default styles of some UI elements reflecting the skin preference,
+- **editor_XYZ.css** and **dialog_XYZ.css**: browser specific CSS hacks.
+
+Other parts:
+- **skin.js**: the only JavaScript part of the skin that registers the skin, its browser specific files and its icons and defines the Chameleon feature,

+/**
+ * Tag-closer extension for CodeMirror.
+ *
+ * This extension adds an "autoCloseTags" option that can be set to
+ * either true to get the default behavior, or an object to further
+ * configure its behavior.
+ *
+ * These are supported options:
+ *
+ * `whenClosing` (default true)
+ *   Whether to autoclose when the '/' of a closing tag is typed.
+ * `whenOpening` (default true)
+ *   Whether to autoclose the tag when the final '>' of an opening
+ *   tag is typed.
+ * `dontCloseTags` (default is empty tags for HTML, none for XML)
+ *   An array of tag names that should not be autoclosed.
+ * `indentTags` (default is block tags for HTML, none for XML)
+ *   An array of tag names that should, when opened, cause a
+ *   blank line to be added inside the tag, and the blank line and
+ *   closing line to be indented.
+ *
+ * See demos/closetag.html for a usage example.

+// CodeMirror, copyright (c) by Marijn Haverbeke and others
+// Distributed under an MIT license: http://codemirror.net/LICENSE
+
+// Glue code between CodeMirror and Tern.
+//
+// Create a CodeMirror.TernServer to wrap an actual Tern server,
+// register open documents (CodeMirror.Doc instances) with it, and
+// call its methods to activate the assisting functions that Tern
+// provides.
+//
+// Options supported (all optional):
+// * defs: An array of JSON definition data structures.
+// * plugins: An object mapping plugin names to configuration
+//   options.
+// * getFile: A function(name, c) that can be used to access files in
+//   the project that haven't been loaded yet. Simply do c(null) to
+//   indicate that a file is not available.
+// * fileFilter: A function(value, docName, doc) that will be applied
+//   to documents before passing them on to Tern.
+// * switchToDoc: A function(name, doc) that should, when providing a
+//   multi-file view, switch the view or focus to the named file.
+// * showError: A function(editor, message) that can be used to
+//   override the way errors are displayed.
+// * completionTip: Customize the content in tooltips for completions.
+//   Is passed a single argument—the completion's data as returned by
+//   Tern—and may return a string, DOM node, or null to indicate that
+//   no tip should be shown. By default the docstring is shown.
+// * typeTip: Like completionTip, but for the tooltips shown for type
+//   queries.
+// * responseFilter: A function(doc, query, request, error, data) that
+//   will be applied to the Tern responses before treating them
+//
+//
+// It is possible to run the Tern server in a web worker by specifying
+// these additional options:
+// * useWorker: Set to true to enable web worker mode. You'll probably
+//   want to feature detect the actual value you use here, for example
+//   !!window.Worker.
+// * workerScript: The main script of the worker. Point this to
+//   wherever you are hosting worker.js from this directory.
+// * workerDeps: An array of paths pointing (relative to workerScript)
+//   to the Acorn and Tern libraries and any Tern plugins you want to
+//   load. Or, if you minified those into a single script and included
+//   them in the workerScript, simply leave this undefined.

+  <h2 id="overview">Overview</h2>
+
+  <p>CodeMirror is a code-editor component that can be embedded in Web pages. The core library provides <em>only</em> the editor component, no accompanying buttons, auto-completion, or other IDE functionality. It does provide a rich API on top of which such functionality can be straightforwardly implemented. See the <a href="#addons">add-ons</a> included in the distribution, and the <a href="https://github.com/jagthedrummer/codemirror-ui">CodeMirror UI</a> project, for reusable implementations of extra features.</p>
+
+  <p>CodeMirror works with language-specific modes. Modes are JavaScript programs that help color (and optionally indent) text written in a given language. The distribution comes with a number of modes (see the <a href="../mode/"><code>mode/</code></a> directory), and it isn't hard to <a href="#modeapi">write new ones</a> for other languages.</p>
+</body>
+</textarea></form>
+
+    <p>This page uses a hack on top of the <code>"renderLine"</code>
+    event to make wrapped text line up with the base indentation of
+    the line.</p>
+
+    <script>
+      var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
+        lineNumbers: true,
+        lineWrapping: true,
+        mode: "text/html"
+      });
+      var charWidth = editor.defaultCharWidth(), basePadding = 4;
+      editor.on("renderLine", function(cm, line, elt) {
+        var off = CodeMirror.countColumn(line.text, null, cm.getOption("tabSize")) * charWidth;
+        elt.style.textIndent = "-" + off + "px";
+        elt.style.paddingLeft = (basePadding + off) + "px";
+      });
+      editor.refresh();

+<h2>Script compression helper</h2>
+
+    <p>To optimize loading CodeMirror, especially when including a
+    bunch of different modes, it is recommended that you combine and
+    minify (and preferably also gzip) the scripts. This page makes
+    those first two steps very easy. Simply select the version and
+    scripts you need in the form below, and
+    click <strong>Compress</strong> to download the minified script
+    file.</p>

+<h2 id=top>(Re-) Implementing A Syntax-Highlighting Editor in JavaScript</h2>
+
+<p style="font-size: 85%" id="intro">
+  <strong>Topic:</strong> JavaScript, code editor implementation<br>
+  <strong>Author:</strong> Marijn Haverbeke<br>
+  <strong>Date:</strong> March 2nd 2011 (updated November 13th 2011)
+</p>
+
+<p style="padding: 0 3em 0 2em"><strong>Caution</strong>: this text was written briefly after
+version 2 was initially written. It no longer (even including the
+update at the bottom) fully represents the current implementation. I'm
+leaving it here as a historic document. For more up-to-date
+information, look at the entries
+tagged <a href="http://marijnhaverbeke.nl/blog/#cm-internals">cm-internals</a>
+on my blog.</p>
+
+<p>This is a followup to
+my <a href="http://codemirror.net/story.html">Brutal Odyssey to the
+Dark Side of the DOM Tree</a> story. That one describes the
+mind-bending process of implementing (what would become) CodeMirror 1.
+This one describes the internals of CodeMirror 2, a complete rewrite
+and rethink of the old code base. I wanted to give this piece another
+Hunter Thompson copycat subtitle, but somehow that would be out of
+place—the process this time around was one of straightforward
+engineering, requiring no serious mind-bending whatsoever.</p>
+
+<p>So, what is wrong with CodeMirror 1? I'd estimate, by mailing list
+activity and general search-engine presence, that it has been
+integrated into about a thousand systems by now. The most prominent
+one, since a few weeks,
+being <a href="http://googlecode.blogspot.com/2011/01/make-quick-fixes-quicker-on-google.html">Google
+code's project hosting</a>. It works, and it's being used widely.</p>
+
+<p>Still, I did not start replacing it because I was bored. CodeMirror
+1 was heavily reliant on <code>designMode</code>
+or <code>contentEditable</code> (depending on the browser). Neither of
+these are well specified (HTML5 tries
+to <a href="http://www.w3.org/TR/html5/editing.html#contenteditable">specify</a>
+their basics), and, more importantly, they tend to be one of the more
+obscure and buggy areas of browser functionality—CodeMirror, by using
+this functionality in a non-typical way, was constantly running up
+against browser bugs. WebKit wouldn't show an empty line at the end of
+the document, and in some releases would suddenly get unbearably slow.
+Firefox would show the cursor in the wrong place. Internet Explorer
+would insist on linkifying everything that looked like a URL or email
+address, a behaviour that can't be turned off. Some bugs I managed to
+work around (which was often a frustrating, painful process), others,
+such as the Firefox cursor placement, I gave up on, and had to tell
+user after user that they were known problems, but not something I
+could help.</p>
+
+<p>Also, there is the fact that <code>designMode</code> (which seemed
+to be less buggy than <code>contentEditable</code> in Webkit and
+Firefox, and was thus used by CodeMirror 1 in those browsers) requires
+a frame. Frames are another tricky area. It takes some effort to
+prevent getting tripped up by domain restrictions, they don't
+initialize synchronously, behave strangely in response to the back
+button, and, on several browsers, can't be moved around the DOM
+without having them re-initialize. They did provide a very nice way to
+namespace the library, though—CodeMirror 1 could freely pollute the
+namespace inside the frame.</p>
+
+<p>Finally, working with an editable document means working with
+selection in arbitrary DOM structures. Internet Explorer (8 and
+before) has an utterly different (and awkward) selection API than all
+of the other browsers, and even among the different implementations of
+<code>document.selection</code>, details about how exactly a selection
+is represented vary quite a bit. Add to that the fact that Opera's
+selection support tended to be very buggy until recently, and you can
+imagine why CodeMirror 1 contains 700 lines of selection-handling
+code.</p>
+
+<p>And that brings us to the main issue with the CodeMirror 1
+code base: The proportion of browser-bug-workarounds to real
+application code was getting dangerously high. By building on top of a
+few dodgy features, I put the system in a vulnerable position—any
+incompatibility and bugginess in these features, I had to paper over
+with my own code. Not only did I have to do some serious stunt-work to
+get it to work on older browsers (as detailed in the
+previous <a href="http://codemirror.net/story.html">story</a>), things
+also kept breaking in newly released versions, requiring me to come up
+with <em>new</em> scary hacks in order to keep up. This was starting
+to lose its appeal.</p>
+
+<section id=approach>
+  <h2>General Approach</h2>
+
+<p>What CodeMirror 2 does is try to sidestep most of the hairy hacks
+that came up in version 1. I owe a lot to the
+<a href="http://ace.ajax.org">ACE</a> editor for inspiration on how to
+approach this.</p>
+
+<p>I absolutely did not want to be completely reliant on key events to
+generate my input. Every JavaScript programmer knows that key event
+information is horrible and incomplete. Some people (most awesomely
+Mihai Bazon with <a href="http://ymacs.org">Ymacs</a>) have been able
+to build more or less functioning editors by directly reading key
+events, but it takes a lot of work (the kind of never-ending, fragile
+work I described earlier), and will never be able to properly support
+things like multi-keystoke international character
+input. <a href="#keymap" class="update">[see below for caveat]</a></p>
+
+<p>So what I do is focus a hidden textarea, and let the browser
+believe that the user is typing into that. What we show to the user is
+a DOM structure we built to represent his document. If this is updated
+quickly enough, and shows some kind of believable cursor, it feels
+like a real text-input control.</p>
+
+<p>Another big win is that this DOM representation does not have to
+span the whole document. Some CodeMirror 1 users insisted that they
+needed to put a 30 thousand line XML document into CodeMirror. Putting
+all that into the DOM takes a while, especially since, for some
+reason, an editable DOM tree is slower than a normal one on most
+browsers. If we have full control over what we show, we must only
+ensure that the visible part of the document has been added, and can
+do the rest only when needed. (Fortunately, the <code>onscroll</code>
+event works almost the same on all browsers, and lends itself well to
+displaying things only as they are scrolled into view.)</p>
+</section>
+<section id="input">
+  <h2>Input</h2>
+
+<p>ACE uses its hidden textarea only as a text input shim, and does
+all cursor movement and things like text deletion itself by directly
+handling key events. CodeMirror's way is to let the browser do its
+thing as much as possible, and not, for example, define its own set of
+key bindings. One way to do this would have been to have the whole
+document inside the hidden textarea, and after each key event update
+the display DOM to reflect what's in that textarea.</p>
+
+<p>That'd be simple, but it is not realistic. For even medium-sized
+document the editor would be constantly munging huge strings, and get
+terribly slow. What CodeMirror 2 does is put the current selection,
+along with an extra line on the top and on the bottom, into the
+textarea.</p>
+
+<p>This means that the arrow keys (and their ctrl-variations), home,
+end, etcetera, do not have to be handled specially. We just read the
+cursor position in the textarea, and update our cursor to match it.
+Also, copy and paste work pretty much for free, and people get their
+native key bindings, without any special work on my part. For example,
+I have emacs key bindings configured for Chrome and Firefox. There is
+no way for a script to detect this. <a class="update"
+href="#keymap">[no longer the case]</a></p>
+
+<p>Of course, since only a small part of the document sits in the
+textarea, keys like page up and ctrl-end won't do the right thing.
+CodeMirror is catching those events and handling them itself.</p>
+</section>
+<section id="selection">
+  <h2>Selection</h2>
+
+<p>Getting and setting the selection range of a textarea in modern
+browsers is trivial—you just use the <code>selectionStart</code>
+and <code>selectionEnd</code> properties. On IE you have to do some
+insane stuff with temporary ranges and compensating for the fact that
+moving the selection by a 'character' will treat \r\n as a single
+character, but even there it is possible to build functions that
+reliably set and get the selection range.</p>
+
+<p>But consider this typical case: When I'm somewhere in my document,
+press shift, and press the up arrow, something gets selected. Then, if
+I, still holding shift, press the up arrow again, the top of my
+selection is adjusted. The selection remembers where its <em>head</em>
+and its <em>anchor</em> are, and moves the head when we shift-move.
+This is a generally accepted property of selections, and done right by
+every editing component built in the past twenty years.</p>
+
+<p>But not something that the browser selection APIs expose.</p>
+
+<p>Great. So when someone creates an 'upside-down' selection, the next
+time CodeMirror has to update the textarea, it'll re-create the
+selection as an 'upside-up' selection, with the anchor at the top, and
+the next cursor motion will behave in an unexpected way—our second
+up-arrow press in the example above will not do anything, since it is
+interpreted in exactly the same way as the first.</p>
+
+<p>No problem. We'll just, ehm, detect that the selection is
+upside-down (you can tell by the way it was created), and then, when
+an upside-down selection is present, and a cursor-moving key is
+pressed in combination with shift, we quickly collapse the selection
+in the textarea to its start, allow the key to take effect, and then
+combine its new head with its old anchor to get the <em>real</em>
+selection.</p>
+
+<p>In short, scary hacks could not be avoided entirely in CodeMirror
+2.</p>
+
+<p>And, the observant reader might ask, how do you even know that a
+key combo is a cursor-moving combo, if you claim you support any
+native key bindings? Well, we don't, but we can learn. The editor
+keeps a set known cursor-movement combos (initialized to the
+predictable defaults), and updates this set when it observes that
+pressing a certain key had (only) the effect of moving the cursor.
+This, of course, doesn't work if the first time the key is used was
+for extending an inverted selection, but it works most of the
+time.</p>
+</section>
+<section id="update">
+  <h2>Intelligent Updating</h2>
+
+<p>One thing that always comes up when you have a complicated internal
+state that's reflected in some user-visible external representation
+(in this case, the displayed code and the textarea's content) is
+keeping the two in sync. The naive way is to just update the display
+every time you change your state, but this is not only error prone
+(you'll forget), it also easily leads to duplicate work on big,
+composite operations. Then you start passing around flags indicating
+whether the display should be updated in an attempt to be efficient
+again and, well, at that point you might as well give up completely.</p>
+
+<p>I did go down that road, but then switched to a much simpler model:
+simply keep track of all the things that have been changed during an
+action, and then, only at the end, use this information to update the
+user-visible display.</p>
+
+<p>CodeMirror uses a concept of <em>operations</em>, which start by
+calling a specific set-up function that clears the state and end by
+calling another function that reads this state and does the required
+updating. Most event handlers, and all the user-visible methods that
+change state are wrapped like this. There's a method
+called <code>operation</code> that accepts a function, and returns
+another function that wraps the given function as an operation.</p>
+
+<p>It's trivial to extend this (as CodeMirror does) to detect nesting,
+and, when an operation is started inside an operation, simply
+increment the nesting count, and only do the updating when this count
+reaches zero again.</p>
+
+<p>If we have a set of changed ranges and know the currently shown
+range, we can (with some awkward code to deal with the fact that
+changes can add and remove lines, so we're dealing with a changing
+coordinate system) construct a map of the ranges that were left
+intact. We can then compare this map with the part of the document
+that's currently visible (based on scroll offset and editor height) to
+determine whether something needs to be updated.</p>
+
+<p>CodeMirror uses two update algorithms—a full refresh, where it just
+discards the whole part of the DOM that contains the edited text and
+rebuilds it, and a patch algorithm, where it uses the information
+about changed and intact ranges to update only the out-of-date parts
+of the DOM. When more than 30 percent (which is the current heuristic,
+might change) of the lines need to be updated, the full refresh is
+chosen (since it's faster to do than painstakingly finding and
+updating all the changed lines), in the other case it does the
+patching (so that, if you scroll a line or select another character,
+the whole screen doesn't have to be
+re-rendered). <span class="update">[the full-refresh
+algorithm was dropped, it wasn't really faster than the patching
+one]</span></p>
+
+<p>All updating uses <code>innerHTML</code> rather than direct DOM
+manipulation, since that still seems to be by far the fastest way to
+build documents. There's a per-line function that combines the
+highlighting, <a href="manual.html#markText">marking</a>, and
+selection info for that line into a snippet of HTML. The patch updater
+uses this to reset individual lines, the refresh updater builds an
+HTML chunk for the whole visible document at once, and then uses a
+single <code>innerHTML</code> update to do the refresh.</p>
+</section>
+<section id="parse">
+  <h2>Parsers can be Simple</h2>
+
+<p>When I wrote CodeMirror 1, I
+thought <a href="http://codemirror.net/story.html#parser">interruptable
+parsers</a> were a hugely scary and complicated thing, and I used a
+bunch of heavyweight abstractions to keep this supposed complexity
+under control: parsers
+were <a href="http://bob.pythonmac.org/archives/2005/07/06/iteration-in-javascript/">iterators</a>
+that consumed input from another iterator, and used funny
+closure-resetting tricks to copy and resume themselves.</p>
+
+<p>This made for a rather nice system, in that parsers formed strictly
+separate modules, and could be composed in predictable ways.
+Unfortunately, it was quite slow (stacking three or four iterators on
+top of each other), and extremely intimidating to people not used to a
+functional programming style.</p>
+
+<p>With a few small changes, however, we can keep all those
+advantages, but simplify the API and make the whole thing less
+indirect and inefficient. CodeMirror
+2's <a href="manual.html#modeapi">mode API</a> uses explicit state
+objects, and makes the parser/tokenizer a function that simply takes a
+state and a character stream abstraction, advances the stream one
+token, and returns the way the token should be styled. This state may
+be copied, optionally in a mode-defined way, in order to be able to
+continue a parse at a given point. Even someone who's never touched a
+lambda in his life can understand this approach. Additionally, far
+fewer objects are allocated in the course of parsing now.</p>
+
+<p>The biggest speedup comes from the fact that the parsing no longer
+has to touch the DOM though. In CodeMirror 1, on an older browser, you
+could <em>see</em> the parser work its way through the document,
+managing some twenty lines in each 50-millisecond time slice it got. It
+was reading its input from the DOM, and updating the DOM as it went
+along, which any experienced JavaScript programmer will immediately
+spot as a recipe for slowness. In CodeMirror 2, the parser usually
+finishes the whole document in a single 100-millisecond time slice—it
+manages some 1500 lines during that time on Chrome. All it has to do
+is munge strings, so there is no real reason for it to be slow
+anymore.</p>
+</section>
+<section id="summary">
+  <h2>What Gives?</h2>
+
+<p>Given all this, what can you expect from CodeMirror 2?</p>
+
+<ul>
+
+<li><strong>Small.</strong> the base library is
+some <span class="update">45k</span> when minified
+now, <span class="update">17k</span> when gzipped. It's smaller than
+its own logo.</li>
+
+<li><strong>Lightweight.</strong> CodeMirror 2 initializes very
+quickly, and does almost no work when it is not focused. This means
+you can treat it almost like a textarea, have multiple instances on a
+page without trouble.</li>
+
+<li><strong>Huge document support.</strong> Since highlighting is
+really fast, and no DOM structure is being built for non-visible
+content, you don't have to worry about locking up your browser when a
+user enters a megabyte-sized document.</li>
+
+<li><strong>Extended API.</strong> Some things kept coming up in the
+mailing list, such as marking pieces of text or lines, which were
+extremely hard to do with CodeMirror 1. The new version has proper
+support for these built in.</li>
+
+<li><strong>Tab support.</strong> Tabs inside editable documents were,
+for some reason, a no-go. At least six different people announced they
+were going to add tab support to CodeMirror 1, none survived (I mean,
+none delivered a working version). CodeMirror 2 no longer removes tabs
+from your document.</li>
+
+<li><strong>Sane styling.</strong> <code>iframe</code> nodes aren't
+really known for respecting document flow. Now that an editor instance
+is a plain <code>div</code> element, it is much easier to size it to
+fit the surrounding elements. You don't even have to make it scroll if
+you do not <a href="../demo/resize.html">want to</a>.</li>
+
+</ul>
+
+<p>On the downside, a CodeMirror 2 instance is <em>not</em> a native
+editable component. Though it does its best to emulate such a
+component as much as possible, there is functionality that browsers
+just do not allow us to hook into. Doing select-all from the context
+menu, for example, is not currently detected by CodeMirror.</p>
+
+<p id="changes" style="margin-top: 2em;"><span style="font-weight:
+bold">[Updates from November 13th 2011]</span> Recently, I've made
+some changes to the codebase that cause some of the text above to no
+longer be current. I've left the text intact, but added markers at the
+passages that are now inaccurate. The new situation is described
+below.</p>
+</section>
+<section id="btree">
+  <h2>Content Representation</h2>
+
+<p>The original implementation of CodeMirror 2 represented the
+document as a flat array of line objects. This worked well—splicing
+arrays will require the part of the array after the splice to be
+moved, but this is basically just a simple <code>memmove</code> of a
+bunch of pointers, so it is cheap even for huge documents.</p>
+
+<p>However, I recently added line wrapping and code folding (line
+collapsing, basically). Once lines start taking up a non-constant
+amount of vertical space, looking up a line by vertical position
+(which is needed when someone clicks the document, and to determine
+the visible part of the document during scrolling) can only be done
+with a linear scan through the whole array, summing up line heights as
+you go. Seeing how I've been going out of my way to make big documents
+fast, this is not acceptable.</p>
+
+<p>The new representation is based on a B-tree. The leaves of the tree
+contain arrays of line objects, with a fixed minimum and maximum size,
+and the non-leaf nodes simply hold arrays of child nodes. Each node
+stores both the amount of lines that live below them and the vertical
+space taken up by these lines. This allows the tree to be indexed both
+by line number and by vertical position, and all access has
+logarithmic complexity in relation to the document size.</p>
+
+<p>I gave line objects and tree nodes parent pointers, to the node
+above them. When a line has to update its height, it can simply walk
+these pointers to the top of the tree, adding or subtracting the
+difference in height from each node it encounters. The parent pointers
+also make it cheaper (in complexity terms, the difference is probably
+tiny in normal-sized documents) to find the current line number when
+given a line object. In the old approach, the whole document array had
+to be searched. Now, we can just walk up the tree and count the sizes
+of the nodes coming before us at each level.</p>
+
+<p>I chose B-trees, not regular binary trees, mostly because they
+allow for very fast bulk insertions and deletions. When there is a big
+change to a document, it typically involves adding, deleting, or
+replacing a chunk of subsequent lines. In a regular balanced tree, all
+these inserts or deletes would have to be done separately, which could
+be really expensive. In a B-tree, to insert a chunk, you just walk
+down the tree once to find where it should go, insert them all in one
+shot, and then break up the node if needed. This breaking up might
+involve breaking up nodes further up, but only requires a single pass
+back up the tree. For deletion, I'm somewhat lax in keeping things
+balanced—I just collapse nodes into a leaf when their child count goes
+below a given number. This means that there are some weird editing
+patterns that may result in a seriously unbalanced tree, but even such
+an unbalanced tree will perform well, unless you spend a day making
+strangely repeating edits to a really big document.</p>
+</section>
+<section id="keymap">
+  <h2>Keymaps</h2>
+
+<p><a href="#approach">Above</a>, I claimed that directly catching key
+events for things like cursor movement is impractical because it
+requires some browser-specific kludges. I then proceeded to explain
+some awful <a href="#selection">hacks</a> that were needed to make it
+possible for the selection changes to be detected through the
+textarea. In fact, the second hack is about as bad as the first.</p>
+
+<p>On top of that, in the presence of user-configurable tab sizes and
+collapsed and wrapped lines, lining up cursor movement in the textarea
+with what's visible on the screen becomes a nightmare. Thus, I've
+decided to move to a model where the textarea's selection is no longer
+depended on.</p>
+
+<p>So I moved to a model where all cursor movement is handled by my
+own code. This adds support for a goal column, proper interaction of
+cursor movement with collapsed lines, and makes it possible for
+vertical movement to move through wrapped lines properly, instead of
+just treating them like non-wrapped lines.</p>
+
+<p>The key event handlers now translate the key event into a string,
+something like <code>Ctrl-Home</code> or <code>Shift-Cmd-R</code>, and
+use that string to look up an action to perform. To make keybinding
+customizable, this lookup goes through
+a <a href="manual.html#option_keyMap">table</a>, using a scheme that
+allows such tables to be chained together (for example, the default
+Mac bindings fall through to a table named 'emacsy', which defines
+basic Emacs-style bindings like <code>Ctrl-F</code>, and which is also
+used by the custom Emacs bindings).</p>
+
+<p>A new
+option <a href="manual.html#option_extraKeys"><code>extraKeys</code></a>
+allows ad-hoc keybindings to be defined in a much nicer way than what
+was possible with the
+old <a href="manual.html#option_onKeyEvent"><code>onKeyEvent</code></a>
+callback. You simply provide an object mapping key identifiers to
+functions, instead of painstakingly looking at raw key events.</p>
+
+<p>Built-in commands map to strings, rather than functions, for
+example <code>"goLineUp"</code> is the default action bound to the up
+arrow key. This allows new keymaps to refer to them without
+duplicating any code. New commands can be defined by assigning to
+the <code>CodeMirror.commands</code> object, which maps such commands
+to functions.</p>
+
+<p>The hidden textarea now only holds the current selection, with no
+extra characters around it. This has a nice advantage: polling for
+input becomes much, much faster. If there's a big selection, this text
+does not have to be read from the textarea every time—when we poll,
+just noticing that something is still selected is enough to tell us
+that no new text was typed.</p>
+
+<p>The reason that cheap polling is important is that many browsers do
+not fire useful events on IME (input method engine) input, which is
+the thing where people inputting a language like Japanese or Chinese
+use multiple keystrokes to create a character or sequence of
+characters. Most modern browsers fire <code>input</code> when the
+composing is finished, but many don't fire anything when the character
+is updated <em>during</em> composition. So we poll, whenever the
+editor is focused, to provide immediate updates of the display.</p>

+    </h2>
+
+    <p>CodeMirror is a code-editor component that can be embedded in
+    Web pages. The core library provides <em>only</em> the editor
+    component, no accompanying buttons, auto-completion, or other IDE
+    functionality. It does provide a rich API on top of which such
+    functionality can be straightforwardly implemented. See
+    the <a href="#addons">addons</a> included in the distribution,
+    and the <a href="https://github.com/marijnh/CodeMirror/wiki/CodeMirror-addons">list
+    of externally hosted addons</a>, for reusable
+    implementations of extra features.</p>
+
+    <p>CodeMirror works with language-specific modes. Modes are
+    JavaScript programs that help color (and optionally indent) text
+    written in a given language. The distribution comes with a number
+    of modes (see the <a href="../mode/"><code>mode/</code></a>
+    directory), and it isn't hard to <a href="#modeapi">write new
+    ones</a> for other languages.</p>
+</section>
+
+<section id=usage>
+    <h2>Basic Usage</h2>
+
+    <p>The easiest way to use CodeMirror is to simply load the script
+    and style sheet found under <code>lib/</code> in the distribution,
+    plus a mode script from one of the <code>mode/</code> directories.
+    (See <a href="compress.html">the compression helper</a> for an
+    easy way to combine scripts.) For example:</p>
+
+    <pre data-lang="text/html">&lt;script src="lib/codemirror.js">&lt;/script>
+&lt;link rel="stylesheet" href="../lib/codemirror.css">
+&lt;script src="mode/javascript/javascript.js">&lt;/script></pre>
+
+    <p>(Alternatively, use a module loader. <a href="#modloader">More
+    about that later.</a>)</p>
+
+    <p>Having done this, an editor instance can be created like
+    this:</p>
+
+    <pre data-lang="javascript">var myCodeMirror = CodeMirror(document.body);</pre>
+
+    <p>The editor will be appended to the document body, will start
+    empty, and will use the mode that we loaded. To have more control
+    over the new editor, a configuration object can be passed
+    to <a href="#CodeMirror"><code>CodeMirror</code></a> as a second
+    argument:</p>
+
+    <pre data-lang="javascript">var myCodeMirror = CodeMirror(document.body, {
+  value: "function myScript(){return 100;}\n",
+  mode:  "javascript"
+});</pre>
+
+    <p>This will initialize the editor with a piece of code already in
+    it, and explicitly tell it to use the JavaScript mode (which is
+    useful when multiple modes are loaded).
+    See <a href="#config">below</a> for a full discussion of the
+    configuration options that CodeMirror accepts.</p>
+
+    <p>In cases where you don't want to append the editor to an
+    element, and need more control over the way it is inserted, the
+    first argument to the <code>CodeMirror</code> function can also
+    be a function that, when given a DOM element, inserts it into the
+    document somewhere. This could be used to, for example, replace a
+    textarea with a real editor:</p>
+
+    <pre data-lang="javascript">var myCodeMirror = CodeMirror(function(elt) {
+  myTextArea.parentNode.replaceChild(elt, myTextArea);
+}, {value: myTextArea.value});</pre>
+
+    <p>However, for this use case, which is a common way to use
+    CodeMirror, the library provides a much more powerful
+    shortcut:</p>
+
+    <pre data-lang="javascript">var myCodeMirror = CodeMirror.fromTextArea(myTextArea);</pre>
+
+    <p>This will, among other things, ensure that the textarea's value
+    is updated with the editor's contents when the form (if it is part
+    of a form) is submitted. See the <a href="#fromTextArea">API
+    reference</a> for a full description of this method.</p>
+
+    <h3 id=modloader>Module loaders</h3>
+
+    <p>The files in the CodeMirror distribution contain shims for
+    loading them (and their dependencies) in AMD or CommonJS
+    environments. If the variables <code>exports</code>
+    and <code>module</code> exist and have type object, CommonJS-style
+    require will be used. If not, but there is a
+    function <code>define</code> with an <code>amd</code> property
+    present, AMD-style (RequireJS) will be used.</p>
+
+    <p>It is possible to
+    use <a href="http://browserify.org/">Browserify</a> or similar
+    tools to statically build modules using CodeMirror. Alternatively,
+    use <a href="http://requirejs.org/">RequireJS</a> to dynamically
+    load dependencies at runtime. Both of these approaches have the
+    advantage that they don't use the global namespace and can, thus,
+    do things like load multiple versions of CodeMirror alongside each
+    other.</p>
+
+    <p>Here's a simple example of using RequireJS to load CodeMirror:</p>
+
+    <pre data-lang="javascript">require([
+  "cm/lib/codemirror", "cm/mode/htmlmixed/htmlmixed"
+], function(CodeMirror) {
+  CodeMirror.fromTextArea(document.getElementById("code"), {
+    lineNumbers: true,
+    mode: "htmlmixed"
+  });
+});</pre>
+
+    <p>It will automatically load the modes that the mixed HTML mode
+    depends on (XML, JavaScript, and CSS).</p>
+
+</section>
+
+<section id=config>
+    <h2>Configuration</h2>
+
+    <p>Both the <a href="#CodeMirror"><code>CodeMirror</code></a>

+
+      <dt id="option_flattenSpans"><code><strong>flattenSpans</strong>: boolean</code></dt>
+      <dd>By default, CodeMirror will combine adjacent tokens into a

+
+      <dt id="option_maxHighlightLength"><code><strong>maxHighlightLength</strong>: number</code></dt>
+      <dd>When highlighting long lines, in order to stay responsive,

+      when <a href="#option_lineWrapping">line wrapping</a>
+      is <strong>off</strong>, will simply be assumed to consist of

+      measuring will be inaccurate when characters of varying size,
+      right-to-left text, markers, or other irregular elements are
+      present. On the other hand, it means that having such a line

+    <h2>Events</h2>
+
+    <p>Various CodeMirror-related objects emit events, which allow
+    client code to react to various situations. Handlers for such
+    events can be registered with the <a href="#on"><code>on</code></a>
+    and <a href="#off"><code>off</code></a> methods on the objects
+    that the event fires on. To fire your own events,
+    use <code>CodeMirror.signal(target, name, args...)</code>,
+    where <code>target</code> is a non-DOM-node object.</p>
+
+    <p>An editor instance fires the following events.
+    The <code>instance</code> argument always refers to the editor
+    itself.</p>
+
+    <dl>
+      <dt id="event_change"><code><strong>"change"</strong> (instance: CodeMirror, changeObj: object)</code></dt>
+      <dd>Fires every time the content of the editor is changed.
+      The <code>changeObj</code> is a <code>{from, to, text, removed,
+      origin}</code> object containing information about the changes
+      that occurred as second argument. <code>from</code>
+      and <code>to</code> are the positions (in the pre-change
+      coordinate system) where the change started and ended (for
+      example, it might be <code>{ch:0, line:18}</code> if the
+      position is at the beginning of line #19). <code>text</code> is
+      an array of strings representing the text that replaced the
+      changed range (split by line). <code>removed</code> is the text
+      that used to be between <code>from</code> and <code>to</code>,
+      which is overwritten by this change.</dd>
+

+
+      <dt id="event_beforeChange"><code><strong>"beforeChange"</strong> (instance: CodeMirror, changeObj: object)</code></dt>
+      <dd>This event is fired before a change is applied, and its

+      The <code>changeObj</code> object
+      has <code>from</code>, <code>to</code>, and <code>text</code>
+      properties, as with
+      the <a href="#event_change"><code>"change"</code></a> event. It
+      also has a <code>cancel()</code> method, which can be called to
+      cancel the change, and, <strong>if</strong> the change isn't
+      coming from an undo or redo event, an <code>update(from, to,
+      text)</code> method, which may be used to modify the change.
+      Undo or redo changes can't be modified, because they hold some
+      metainformation for restoring old marked ranges that is only
+      valid for that specific change. All three arguments
+      to <code>update</code> are optional, and can be left off to
+      leave the existing value for that field
+      intact. <strong>Note:</strong> you may not do anything from
+      a <code>"beforeChange"</code> handler that would cause changes
+      to the document or its visualization. Doing so will, since this
+      handler is called directly from the bowels of the CodeMirror

+    <h2>Key Maps</h2>
+
+    <p>Key maps are ways to associate keys with functionality. A key map
+    is an object mapping strings that identify the keys to functions
+    that implement their functionality.</p>
+
+    <p>The CodeMirror distributions comes
+    with <a href="../demo/emacs.html">Emacs</a>, <a href="../demo/vim.html">Vim</a>,
+    and <a href="../demo/sublime.html">Sublime Text</a>-style keymaps.</p>
+
+    <p>Keys are identified either by name or by character.
+    The <code>CodeMirror.keyNames</code> object defines names for
+    common keys and associates them with their key codes. Examples of
+    names defined here are <code>Enter</code>, <code>F5</code>,
+    and <code>Q</code>. These can be prefixed
+    with <code>Shift-</code>, <code>Cmd-</code>, <code>Ctrl-</code>,
+    and <code>Alt-</code> (in that order!) to specify a modifier. So
+    for example, <code>Shift-Ctrl-Space</code> would be a valid key
+    identifier.</p>
+
+    <p>Common example: map the Tab key to insert spaces instead of a tab
+    character.</p>
+
+    <pre data-lang="javascript">
+{
+  Tab: function(cm) {
+    var spaces = Array(cm.getOption("indentUnit") + 1).join(" ");
+    cm.replaceSelection(spaces);
+  }
+}</pre>
+
+    <p>Alternatively, a character can be specified directly by
+    surrounding it in single quotes, for example <code>'$'</code>
+    or <code>'q'</code>. Due to limitations in the way browsers fire
+    key events, these may not be prefixed with modifiers.</p>
+
+    <p>The <code>CodeMirror.keyMap</code> object associates key maps
+    with names. User code and key map definitions can assign extra
+    properties to this object. Anywhere where a key map is expected, a
+    string can be given, which will be looked up in this object. It
+    also contains the <code>"default"</code> key map holding the
+    default bindings.</p>
+
+    <p>The values of properties in key maps can be either functions of
+    a single argument (the CodeMirror instance), strings, or
+    <code>false</code>. Strings refer
+    to <a href="#commands">commands</a>, which are described below. If
+    the property is set to <code>false</code>, CodeMirror leaves
+    handling of the key up to the browser. A key handler function may
+    return <code>CodeMirror.Pass</code> to indicate that it has
+    decided not to handle the key, and other handlers (or the default
+    behavior) should be given a turn.</p>
+
+    <p>Keys mapped to command names that start with the
+    characters <code>"go"</code> (which should be used for
+    cursor-movement actions) will be fired even when an
+    extra <code>Shift</code> modifier is present (i.e. <code>"Up":
+    "goLineUp"</code> matches both up and shift-up). This is used to
+    easily implement shift-selection.</p>
+
+    <p>Key maps can defer to each other by defining
+    a <code>fallthrough</code> property. This indicates that when a
+    key is not found in the map itself, one or more other maps should
+    be searched. It can hold either a single key map or an array of
+    key maps.</p>
+
+    <p>When a key map contains a <code>nofallthrough</code> property
+    set to <code>true</code>, keys matched against that map will be
+    ignored if they don't match any of the bindings in the map (no
+    further child maps will be tried). When
+    the <code>disableInput</code> property is set
+    to <code>true</code>, the default effect of inserting a character
+    will be suppressed when the key map is active as the top-level
+    map.</p>

+
+<section id=commands>
+    <h2>Commands</h2>
+
+    <p>Commands are parameter-less actions that can be performed on an
+    editor. Their main use is for key bindings. Commands are defined by
+    adding properties to the <code>CodeMirror.commands</code> object.
+    A number of common commands are defined by the library itself,
+    most of them used by the default key bindings. The value of a
+    command property must be a function of one argument (an editor
+    instance).</p>
+
+    <p>Some of the commands below are referenced in the default
+    key map, but not defined by the core library. These are intended to
+    be defined by user code or addons.</p>
+
+    <p>Commands can also be run with
+    the <a href="#execCommand"><code>execCommand</code></a>
+    method.</p>

+    <h2>Customized Styling</h2>
+
+    <p>Up to a certain extent, CodeMirror's look can be changed by
+    modifying style sheet files. The style sheets supplied by modes
+    simply provide the colors for that mode, and can be adapted in a
+    very straightforward way. To style the editor itself, it is
+    possible to alter or override the styles defined
+    in <a href="../lib/codemirror.css"><code>codemirror.css</code></a>.</p>
+
+    <p>Some care must be taken there, since a lot of the rules in this
+    file are necessary to have CodeMirror function properly. Adjusting
+    colors should be safe, of course, and with some care a lot of
+    other things can be changed as well. The CSS classes defined in
+    this file serve the following roles:</p>
+
+    <dl>
+      <dt id="class_CodeMirror"><code><strong>CodeMirror</strong></code></dt>
+      <dd>The outer element of the editor. This should be used for the
+      editor width, height, borders and positioning. Can also be used
+      to set styles that should hold for everything inside the editor
+      (such as font and font size), or to set a background.</dd>
+
+      <dt id="class_CodeMirror_scroll"><code><strong>CodeMirror-scroll</strong></code></dt>
+      <dd>Whether the editor scrolls (<code>overflow: auto</code> +
+      fixed height). By default, it does. Setting
+      the <code>CodeMirror</code> class to have <code>height:
+      auto</code> and giving this class <code>overflow-x: auto;
+      overflow-y: hidden;</code> will cause the editor
+      to <a href="../demo/resize.html">resize to fit its
+      content</a>.</dd>
+
+      <dt id="class_CodeMirror_focused"><code><strong>CodeMirror-focused</strong></code></dt>
+      <dd>Whenever the editor is focused, the top element gets this
+      class. This is used to hide the cursor and give the selection a
+      different color when the editor is not focused.</dd>
+
+      <dt id="class_CodeMirror_gutters"><code><strong>CodeMirror-gutters</strong></code></dt>
+      <dd>This is the backdrop for all gutters. Use it to set the
+      default gutter background color, and optionally add a border on
+      the right of the gutters.</dd>
+
+      <dt id="class_CodeMirror_linenumbers"><code><strong>CodeMirror-linenumbers</strong></code></dt>
+      <dd>Use this for giving a background or width to the line number
+      gutter.</dd>
+
+      <dt id="class_CodeMirror_linenumber"><code><strong>CodeMirror-linenumber</strong></code></dt>
+      <dd>Used to style the actual individual line numbers. These
+      won't be children of the <code>CodeMirror-linenumbers</code>
+      (plural) element, but rather will be absolutely positioned to
+      overlay it. Use this to set alignment and text properties for

+    <h2>Programming API</h2>
+
+    <p>A lot of CodeMirror features are only available through its
+    API. Thus, you need to write code (or
+    use <a href="#addons">addons</a>) if you want to expose them to
+    your users.</p>
+
+    <p>Whenever points in the document are represented, the API uses
+    objects with <code>line</code> and <code>ch</code> properties.
+    Both are zero-based. CodeMirror makes sure to 'clip' any positions
+    passed by client code so that they fit inside the document, so you
+    shouldn't worry too much about sanitizing your coordinates. If you
+    give <code>ch</code> a value of <code>null</code>, or don't
+    specify it, it will be replaced with the length of the specified
+    line.</p>
+
+    <p>Methods prefixed with <code>doc.</code> can, unless otherwise
+    specified, be called both on <code>CodeMirror</code> (editor)
+    instances and <code>CodeMirror.Doc</code> instances. Methods
+    prefixed with <code>cm.</code> are <em>only</em> available
+    on <code>CodeMirror</code> instances.</p>
+
+    <h3 id="api_constructor">Constructor</h3>
+
+    <p id="CodeMirror">Constructing an editor instance is done with
+    the <code><strong>CodeMirror</strong>(place: Element|fn(Element),
+    ?option: object)</code> constructor. If the <code>place</code>
+    argument is a DOM element, the editor will be appended to it. If
+    it is a function, it will be called, and is expected to place the
+    editor into the document. <code>options</code> may be an element
+    mapping <a href="#config">option names</a> to values. The options
+    that it doesn't explicitly specify (or all options, if it is not
+    passed) will be taken
+    from <a href="#defaults"><code>CodeMirror.defaults</code></a>.</p>
+
+    <p>Note that the options object passed to the constructor will be
+    mutated when the instance's options
+    are <a href="#setOption">changed</a>, so you shouldn't share such

+    <h2>Writing CodeMirror Modes</h2>
+
+    <p>Modes typically consist of a single JavaScript file. This file
+    defines, in the simplest case, a lexer (tokenizer) for your
+    language—a function that takes a character stream as input,
+    advances it past a token, and returns a style for that token. More
+    advanced modes can also handle indentation for the language.</p>
+
+    <p id="defineMode">The mode script should
+    call <code><strong>CodeMirror.defineMode</strong></code> to
+    register itself with CodeMirror. This function takes two
+    arguments. The first should be the name of the mode, for which you
+    should use a lowercase string, preferably one that is also the
+    name of the files that define the mode (i.e. <code>"xml"</code> is
+    defined in <code>xml.js</code>). The second argument should be a
+    function that, given a CodeMirror configuration object (the thing
+    passed to the <code>CodeMirror</code> function) and an optional
+    mode configuration object (as in
+    the <a href="#option_mode"><code>mode</code></a> option), returns
+    a mode object.</p>
+
+    <p>Typically, you should use this second argument
+    to <code>defineMode</code> as your module scope function (modes
+    should not leak anything into the global scope!), i.e. write your
+    whole mode inside this function.</p>
+
+    <p>The main responsibility of a mode script is <em>parsing</em>
+    the content of the editor. Depending on the language and the
+    amount of functionality desired, this can be done in really easy
+    or extremely complicated ways. Some parsers can be stateless,
+    meaning that they look at one element (<em>token</em>) of the code
+    at a time, with no memory of what came before. Most, however, will
+    need to remember something. This is done by using a <em>state
+    object</em>, which is an object that is always passed when
+    reading a token, and which can be mutated by the tokenizer.</p>
+
+    <p id="startState">Modes that use a state must define
+    a <code><strong>startState</strong></code> method on their mode
+    object. This is a function of no arguments that produces a state
+    object to be used at the start of a document.</p>
+
+    <p id="token">The most important part of a mode object is
+    its <code><strong>token</strong>(stream, state)</code> method. All
+    modes must define this method. It should read one token from the
+    stream it is given as an argument, optionally update its state,
+    and return a style string, or <code>null</code> for tokens that do
+    not have to be styled. For your styles, you are encouraged to use
+    the 'standard' names defined in the themes (without
+    the <code>cm-</code> prefix). If that fails, it is also possible
+    to come up with your own and write your own CSS theme file.<p>
+
+    <p id="token_style_line">A typical token string would
+    be <code>"variable"</code> or <code>"comment"</code>. Multiple
+    styles can be returned (separated by spaces), for
+    example <code>"string error"</code> for a thing that looks like a
+    string but is invalid somehow (say, missing its closing quote).
+    When a style is prefixed by <code>"line-"</code>
+    or <code>"line-background-"</code>, the style will be applied to
+    the whole line, analogous to what
+    the <a href="#addLineClass"><code>addLineClass</code></a> method
+    does—styling the <code>"text"</code> in the simple case, and
+    the <code>"background"</code> element
+    when <code>"line-background-"</code> is prefixed.</p>
+
+    <p id="StringStream">The stream object that's passed
+    to <code>token</code> encapsulates a line of code (tokens may
+    never span lines) and our current position in that line. It has
+    the following API:</p>
+
+    <dl>
+      <dt><code><strong>eol</strong>() → boolean</code></dt>
+      <dd>Returns true only if the stream is at the end of the
+      line.</dd>
+      <dt><code><strong>sol</strong>() → boolean</code></dt>
+      <dd>Returns true only if the stream is at the start of the
+      line.</dd>
+
+      <dt><code><strong>peek</strong>() → string</code></dt>
+      <dd>Returns the next character in the stream without advancing
+      it. Will return an <code>null</code> at the end of the
+      line.</dd>
+      <dt><code><strong>next</strong>() → string</code></dt>
+      <dd>Returns the next character in the stream and advances it.
+      Also returns <code>null</code> when no more characters are
+      available.</dd>
+
+      <dt><code><strong>eat</strong>(match: string|regexp|function(char: string) → boolean) → string</code></dt>
+      <dd><code>match</code> can be a character, a regular expression,
+      or a function that takes a character and returns a boolean. If
+      the next character in the stream 'matches' the given argument,
+      it is consumed and returned. Otherwise, <code>undefined</code>
+      is returned.</dd>
+      <dt><code><strong>eatWhile</strong>(match: string|regexp|function(char: string) → boolean) → boolean</code></dt>
+      <dd>Repeatedly calls <code>eat</code> with the given argument,
+      until it fails. Returns true if any characters were eaten.</dd>
+      <dt><code><strong>eatSpace</strong>() → boolean</code></dt>
+      <dd>Shortcut for <code>eatWhile</code> when matching
+      white-space.</dd>
+      <dt><code><strong>skipToEnd</strong>()</code></dt>
+      <dd>Moves the position to the end of the line.</dd>
+      <dt><code><strong>skipTo</strong>(ch: string) → boolean</code></dt>
+      <dd>Skips to the next occurrence of the given character, if
+      found on the current line (doesn't advance the stream if the
+      character does not occur on the line). Returns true if the
+      character was found.</dd>
+      <dt><code><strong>match</strong>(pattern: string, ?consume: boolean, ?caseFold: boolean) → boolean</code></dt>
+      <dt><code><strong>match</strong>(pattern: regexp, ?consume: boolean) → array&lt;string&gt;</code></dt>
+      <dd>Act like a
+      multi-character <code>eat</code>—if <code>consume</code> is true
+      or not given—or a look-ahead that doesn't update the stream
+      position—if it is false. <code>pattern</code> can be either a
+      string or a regular expression starting with <code>^</code>.
+      When it is a string, <code>caseFold</code> can be set to true to
+      make the match case-insensitive. When successfully matching a
+      regular expression, the returned value will be the array
+      returned by <code>match</code>, in case you need to extract
+      matched groups.</dd>
+
+      <dt><code><strong>backUp</strong>(n: integer)</code></dt>
+      <dd>Backs up the stream <code>n</code> characters. Backing it up
+      further than the start of the current token will cause things to
+      break, so be careful.</dd>
+      <dt><code><strong>column</strong>() → integer</code></dt>
+      <dd>Returns the column (taking into account tabs) at which the
+      current token starts.</dd>
+      <dt><code><strong>indentation</strong>() → integer</code></dt>
+      <dd>Tells you how far the current line has been indented, in
+      spaces. Corrects for tab characters.</dd>
+
+      <dt><code><strong>current</strong>() → string</code></dt>
+      <dd>Get the string between the start of the current token and
+      the current stream position.</dd>
+    </dl>
+
+    <p id="blankLine">By default, blank lines are simply skipped when
+    tokenizing a document. For languages that have significant blank
+    lines, you can define
+    a <code><strong>blankLine</strong>(state)</code> method on your
+    mode that will get called whenever a blank line is passed over, so
+    that it can update the parser state.</p>
+
+    <p id="copyState">Because state object are mutated, and CodeMirror
+    needs to keep valid versions of a state around so that it can
+    restart a parse at any line, copies must be made of state objects.
+    The default algorithm used is that a new state object is created,
+    which gets all the properties of the old object. Any properties
+    which hold arrays get a copy of these arrays (since arrays tend to
+    be used as mutable stacks). When this is not correct, for example
+    because a mode mutates non-array properties of its state object, a
+    mode object should define
+    a <code><strong>copyState</strong></code> method, which is given a
+    state and should return a safe copy of that state.</p>
+
+    <p id="indent">If you want your mode to provide smart indentation
+    (through the <a href="#indentLine"><code>indentLine</code></a>
+    method and the <code>indentAuto</code>
+    and <code>newlineAndIndent</code> commands, to which keys can be
+    <a href="#option_extraKeys">bound</a>), you must define
+    an <code><strong>indent</strong>(state, textAfter)</code> method
+    on your mode object.</p>
+
+    <p>The indentation method should inspect the given state object,
+    and optionally the <code>textAfter</code> string, which contains
+    the text on the line that is being indented, and return an
+    integer, the amount of spaces to indent. It should usually take
+    the <a href="#option_indentUnit"><code>indentUnit</code></a>
+    option into account. An indentation method may
+    return <code>CodeMirror.Pass</code> to indicate that it
+    could not come up with a precise indentation.</p>
+
+    <p id="mode_comment">To work well with
+    the <a href="#addon_comment">commenting addon</a>, a mode may
+    define <code><strong>lineComment</strong></code> (string that
+    starts a line
+    comment), <code><strong>blockCommentStart</strong></code>, <code><strong>blockCommentEnd</strong></code>
+    (strings that start and end block comments),
+    and <code>blockCommentLead</code> (a string to put at the start of
+    continued lines in a block comment). All of these are
+    optional.</p>
+
+    <p id="electricChars">Finally, a mode may define either
+    an <code>electricChars</code> or an <code>electricInput</code>
+    property, which are used to automatically reindent the line when
+    certain patterns are typed and
+    the <a href="#option_electricChars"><code>electricChars</code></a>
+    option is enabled. <code>electricChars</code> may be a string, and
+    will trigger a reindent whenever one of the characters in that
+    string are typed. Often, it is more appropriate to
+    use <code>electricInput</code>, which should hold a regular
+    expression, and will trigger indentation when the part of the
+    line <em>before</em> the cursor matches the expression. It should
+    usually end with a <code>$</code> character, so that it only
+    matches when the indentation-changing pattern was just typed, not when something was
+    typed after the pattern.</p>
+
+    <p>So, to summarize, a mode <em>must</em> provide
+    a <code>token</code> method, and it <em>may</em>
+    provide <code>startState</code>, <code>copyState</code>,
+    and <code>indent</code> methods. For an example of a trivial mode,
+    see the <a href="../mode/diff/diff.js">diff mode</a>, for a more
+    involved example, see the <a href="../mode/clike/clike.js">C-like
+    mode</a>.</p>
+
+    <p>Sometimes, it is useful for modes to <em>nest</em>—to have one
+    mode delegate work to another mode. An example of this kind of
+    mode is the <a href="../mode/htmlmixed/htmlmixed.js">mixed-mode HTML
+    mode</a>. To implement such nesting, it is usually necessary to
+    create mode objects and copy states yourself. To create a mode
+    object, there are <code>CodeMirror.getMode(options,
+    parserConfig)</code>, where the first argument is a configuration
+    object as passed to the mode constructor function, and the second
+    argument is a mode specification as in
+    the <a href="#option_mode"><code>mode</code></a> option. To copy a
+    state object, call <code>CodeMirror.copyState(mode, state)</code>,
+    where <code>mode</code> is the mode that created the given
+    state.</p>
+
+    <p id="innerMode">In a nested mode, it is recommended to add an
+    extra method, <code><strong>innerMode</strong></code> which, given
+    a state object, returns a <code>{state, mode}</code> object with
+    the inner mode and its state for the current position. These are
+    used by utility scripts such as the <a href="#addon_closetag">tag
+    closer</a> to get context information. Use
+    the <code>CodeMirror.innerMode</code> helper function to, starting
+    from a mode and a state, recursively walk down to the innermost
+    mode and state.</p>
+
+    <p>To make indentation work properly in a nested parser, it is
+    advisable to give the <code>startState</code> method of modes that
+    are intended to be nested an optional argument that provides the
+    base indentation for the block of code. The JavaScript and CSS
+    parser do this, for example, to allow JavaScript and CSS code
+    inside the mixed-mode HTML mode to be properly indented.</p>
+
+    <p id="defineMIME">It is possible, and encouraged, to associate
+    your mode, or a certain configuration of your mode, with
+    a <a href="http://en.wikipedia.org/wiki/MIME">MIME</a> type. For
+    example, the JavaScript mode associates itself
+    with <code>text/javascript</code>, and its JSON variant
+    with <code>application/json</code>. To do this,
+    call <code><strong>CodeMirror.defineMIME</strong>(mime,
+    modeSpec)</code>, where <code>modeSpec</code> can be a string or
+    object specifying a mode, as in
+    the <a href="#option_mode"><code>mode</code></a> option.</p>
+
+    <p>If a mode specification wants to add some properties to the
+    resulting mode object, typically for use
+    with <a href="#getHelpers"><code>getHelpers</code></a>, it may
+    contain a <code>modeProps</code> property, which holds an object.
+    This object's properties will be copied to the actual mode
+    object.</p>
+
+    <p id="extendMode">Sometimes, it is useful to add or override mode
+    object properties from external code.
+    The <code><strong>CodeMirror.extendMode</strong></code> function
+    can be used to add properties to mode objects produced for a
+    specific mode. Its first argument is the name of the mode, its
+    second an object that specifies the properties that should be
+    added. This is mostly useful to add utilities that can later be
+    looked up through <a href="#getMode"><code>getMode</code></a>.</p>

+<h2>Reporting bugs effectively</h2>
+
+<div class="left">
+
+<p>So you found a problem in CodeMirror. By all means, report it! Bug
+reports from users are the main drive behind improvements to
+CodeMirror. But first, please read over these points:</p>
+
+<ol>
+  <li>CodeMirror is maintained by volunteers. They don't owe you
+  anything, so be polite. Reports with an indignant or belligerent
+  tone tend to be moved to the bottom of the pile.</li>
+
+  <li>Include information about <strong>the browser in which the
+  problem occurred</strong>. Even if you tested several browsers, and
+  the problem occurred in all of them, mention this fact in the bug
+  report. Also include browser version numbers and the operating
+  system that you're on.</li>
+
+  <li>Mention which release of CodeMirror you're using. Preferably,
+  try also with the current development snapshot, to ensure the
+  problem has not already been fixed.</li>
+
+  <li>Mention very precisely what went wrong. "X is broken" is not a
+  good bug report. What did you expect to happen? What happened
+  instead? Describe the exact steps a maintainer has to take to make
+  the problem occur. We can not fix something that we can not
+  observe.</li>
+
+  <li>If the problem can not be reproduced in any of the demos
+  included in the CodeMirror distribution, please provide an HTML
+  document that demonstrates the problem. The best way to do this is
+  to go to <a href="http://jsbin.com/ihunin/1/edit">jsbin.com</a>, enter
+  it there, press save, and include the resulting link in your bug
+  report.</li>

+<article>
+
+<h2>Upgrading to v2.2</h2>
+
+<p>There are a few things in the 2.2 release that require some care
+when upgrading.</p>
+
+<h3>No more default.css</h3>
+
+<p>The default theme is now included
+in <a href="../lib/codemirror.css"><code>codemirror.css</code></a>, so
+you do not have to included it separately anymore. (It was tiny, so
+even if you're not using it, the extra data overhead is negligible.)
+
+<h3>Different key customization</h3>
+
+<p>CodeMirror has moved to a system
+where <a href="manual.html#option_keyMap">keymaps</a> are used to
+bind behavior to keys. This means <a href="../demo/emacs.html">custom
+bindings</a> are now possible.</p>
+
+<p>Three options that influenced key
+behavior, <code>tabMode</code>, <code>enterMode</code>,
+and <code>smartHome</code>, are no longer supported. Instead, you can
+provide custom bindings to influence the way these keys act. This is
+done through the
+new <a href="manual.html#option_extraKeys"><code>extraKeys</code></a>
+option, which can hold an object mapping key names to functionality. A
+simple example would be:</p>
+
+<pre>  extraKeys: {
+    "Ctrl-S": function(instance) { saveText(instance.getValue()); },
+    "Ctrl-/": "undo"
+  }</pre>
+
+<p>Keys can be mapped either to functions, which will be given the
+editor instance as argument, or to strings, which are mapped through
+functions through the <code>CodeMirror.commands</code> table, which
+contains all the built-in editing commands, and can be inspected and
+extended by external code.</p>
+
+<p>By default, the <code>Home</code> key is bound to
+the <code>"goLineStartSmart"</code> command, which moves the cursor to
+the first non-whitespace character on the line. You can set do this to
+make it always go to the very start instead:</p>
+
+<pre>  extraKeys: {"Home": "goLineStart"}</pre>
+
+<p>Similarly, <code>Enter</code> is bound
+to <code>"newlineAndIndent"</code> by default. You can bind it to
+something else to get different behavior. To disable special handling
+completely and only get a newline character inserted, you can bind it
+to <code>false</code>:</p>
+
+<pre>  extraKeys: {"Enter": false}</pre>
+
+<p>The same works for <code>Tab</code>. If you don't want CodeMirror
+to handle it, bind it to <code>false</code>. The default behaviour is
+to indent the current line more (<code>"indentMore"</code> command),
+and indent it less when shift is held (<code>"indentLess"</code>).
+There are also <code>"indentAuto"</code> (smart indent)
+and <code>"insertTab"</code> commands provided for alternate
+behaviors. Or you can write your own handler function to do something
+different altogether.</p>
+
+<h3>Tabs</h3>
+
+<p>Handling of tabs changed completely. The display width of tabs can
+now be set with the <code>tabSize</code> option, and tabs can
+be <a href="../demo/visibletabs.html">styled</a> by setting CSS rules
+for the <code>cm-tab</code> class.</p>
+
+<p>The default width for tabs is now 4, as opposed to the 8 that is
+hard-wired into browsers. If you are relying on 8-space tabs, make
+sure you explicitly set <code>tabSize: 8</code> in your options.</p>

+
+<h2 id=upgrade>Upgrading to version 3</h2>
+
+<p>Version 3 does not depart too much from 2.x API, and sites that use
+CodeMirror in a very simple way might be able to upgrade without
+trouble. But it does introduce a number of incompatibilities. Please
+at least skim this text before upgrading.</p>
+
+<p>Note that <strong>version 3 drops full support for Internet
+Explorer 7</strong>. The editor will mostly work on that browser, but
+it'll be significantly glitchy.</p>
+
+<section id=dom>
+  <h2>DOM structure</h2>
+
+<p>This one is the most likely to cause problems. The internal
+structure of the editor has changed quite a lot, mostly to implement a
+new scrolling model.</p>
+
+<p>Editor height is now set on the outer wrapper element (CSS
+class <code>CodeMirror</code>), not on the scroller element
+(<code>CodeMirror-scroll</code>).</p>
+
+<p>Other nodes were moved, dropped, and added. If you have any code
+that makes assumptions about the internal DOM structure of the editor,
+you'll have to re-test it and probably update it to work with v3.</p>
+
+<p>See the <a href="manual.html#styling">styling section</a> of the
+manual for more information.</p>
+</section>
+<section id=gutters>
+  <h2>Gutter model</h2>
+
+<p>In CodeMirror 2.x, there was a single gutter, and line markers
+created with <code>setMarker</code> would have to somehow coexist with
+the line numbers (if present). Version 3 allows you to specify an
+array of gutters, <a href="manual.html#option_gutters">by class
+name</a>,
+use <a href="manual.html#setGutterMarker"><code>setGutterMarker</code></a>
+to add or remove markers in individual gutters, and clear whole
+gutters
+with <a href="manual.html#clearGutter"><code>clearGutter</code></a>.
+Gutter markers are now specified as DOM nodes, rather than HTML
+snippets.</p>
+
+<p>The gutters no longer horizontally scrolls along with the content.
+The <code>fixedGutter</code> option was removed (since it is now the
+only behavior).</p>
+
+<pre data-lang="text/html">
+&lt;style>
+  /* Define a gutter style */
+  .note-gutter { width: 3em; background: cyan; }
+&lt;/style>
+&lt;script>
+  // Create an instance with two gutters -- line numbers and notes
+  var cm = new CodeMirror(document.body, {
+    gutters: ["note-gutter", "CodeMirror-linenumbers"],
+    lineNumbers: true
+  });
+  // Add a note to line 0
+  cm.setGutterMarker(0, "note-gutter", document.createTextNode("hi"));
+&lt;/script>
+</pre>
+</section>
+<section id=events>
+  <h2>Event handling</h2>
+
+<p>Most of the <code>onXYZ</code> options have been removed. The same
+effect is now obtained by calling
+the <a href="manual.html#on"><code>on</code></a> method with a string
+identifying the event type. Multiple handlers can now be registered
+(and individually unregistered) for an event, and objects such as line
+handlers now also expose events. See <a href="manual.html#events">the
+full list here</a>.</p>
+
+<p>(The <code>onKeyEvent</code> and <code>onDragEvent</code> options,
+which act more as hooks than as event handlers, are still there in
+their old form.)</p>
+
+<pre data-lang="javascript">
+cm.on("change", function(cm, change) {
+  console.log("something changed! (" + change.origin + ")");
+});
+</pre>
+</section>
+<section id=marktext>
+  <h2>markText method arguments</h2>
+
+<p>The <a href="manual.html#markText"><code>markText</code></a> method
+(which has gained some interesting new features, such as creating
+atomic and read-only spans, or replacing spans with widgets) no longer
+takes the CSS class name as a separate argument, but makes it an
+optional field in the options object instead.</p>
+
+<pre data-lang="javascript">
+// Style first ten lines, and forbid the cursor from entering them
+cm.markText({line: 0, ch: 0}, {line: 10, ch: 0}, {
+  className: "magic-text",
+  inclusiveLeft: true,
+  atomic: true
+});
+</pre>
+</section>
+<section id=folding>
+  <h2>Line folding</h2>
+
+<p>The interface for hiding lines has been
+removed. <a href="manual.html#markText"><code>markText</code></a> can
+now be used to do the same in a more flexible and powerful way.</p>
+
+<p>The <a href="../demo/folding.html">folding script</a> has been
+updated to use the new interface, and should now be more robust.</p>
+
+<pre data-lang="javascript">
+// Fold a range, replacing it with the text "??"
+var range = cm.markText({line: 4, ch: 2}, {line: 8, ch: 1}, {
+  replacedWith: document.createTextNode("??"),
+  // Auto-unfold when cursor moves into the range
+  clearOnEnter: true
+});
+// Get notified when auto-unfolding
+CodeMirror.on(range, "clear", function() {
+  console.log("boom");
+});
+</pre>
+</section>
+<section id=lineclass>
+  <h2>Line CSS classes</h2>
+
+<p>The <code>setLineClass</code> method has been replaced
+by <a href="manual.html#addLineClass"><code>addLineClass</code></a>
+and <a href="manual.html#removeLineClass"><code>removeLineClass</code></a>,
+which allow more modular control over the classes attached to a line.</p>
+
+<pre data-lang="javascript">
+var marked = cm.addLineClass(10, "background", "highlighted-line");
+setTimeout(function() {
+  cm.removeLineClass(marked, "background", "highlighted-line");
+});
+</pre>
+</section>
+<section id=positions>
+  <h2>Position properties</h2>
+
+<p>All methods that take or return objects that represent screen
+positions now use <code>{left, top, bottom, right}</code> properties
+(not always all of them) instead of the <code>{x, y, yBot}</code> used
+by some methods in v2.x.</p>
+
+<p>Affected methods
+are <a href="manual.html#cursorCoords"><code>cursorCoords</code></a>, <a href="manual.html#charCoords"><code>charCoords</code></a>, <a href="manual.html#coordsChar"><code>coordsChar</code></a>,
+and <a href="manual.html#getScrollInfo"><code>getScrollInfo</code></a>.</p>
+</section>
+<section id=matchbrackets>
+  <h2>Bracket matching no longer in core</h2>
+
+<p>The <a href="manual.html#addon_matchbrackets"><code>matchBrackets</code></a>
+option is no longer defined in the core editor.
+Load <code>addon/edit/matchbrackets.js</code> to enable it.</p>
+</section>
+<section id=modes>
+  <h2>Mode management</h2>
+
+<p>The <code>CodeMirror.listModes</code>
+and <code>CodeMirror.listMIMEs</code> functions, used for listing
+defined modes, are gone. You are now encouraged to simply
+inspect <code>CodeMirror.modes</code> (mapping mode names to mode
+constructors) and <code>CodeMirror.mimeModes</code> (mapping MIME
+strings to mode specs).</p>
+</section>
+<section id=new>
+  <h2>New features</h2>
+
+<p>Some more reasons to upgrade to version 3.</p>
+
+<ul>
+  <li>Bi-directional text support. CodeMirror will now mostly do the
+  right thing when editing Arabic or Hebrew text.</li>
+  <li>Arbitrary line heights. Using fonts with different heights
+  inside the editor (whether off by one pixel or fifty) is now
+  supported and handled gracefully.</li>
+  <li>In-line widgets. See <a href="../demo/widget.html">the demo</a>
+  and <a href="manual.html#addLineWidget">the docs</a>.</li>
+  <li>Defining custom options
+  with <a href="manual.html#defineOption"><code>CodeMirror.defineOption</code></a>.</li>

+<h2 id=upgrade>Upgrading to version 4</h2>
+
+<p>CodeMirror 4's interface is <em>very</em> close version 3, but it
+does fix a few awkward details in a backwards-incompatible ways. At
+least skim the text below before upgrading.</p>
+
+<section id=multisel><h2>Multiple selections</h2>
+
+<p>The main new feature in version 4 is multiple selections. The
+single-selection variants of methods are still there, but now
+typically act only on the <em>primary</em> selection (usually the last
+one added).</p>
+
+<p>The exception to this
+is <a href="manual.html#getSelection"><strong><code>getSelection</code></strong></a>,
+which will now return the content of <em>all</em> selections
+(separated by newlines, or whatever <code>lineSep</code> parameter you passed
+it).</p>
+
+</section>
+
+<section id=beforeSelectionChange><h2>The beforeSelectionChange event</h2>
+
+<p>This event still exists, but the object it is passed has
+a <a href="manual.html#event_beforeSelectionChange">completely new
+interface</a>, because such changes now concern multiple
+selections.</p>
+
+</section>
+
+<section id=replaceSelection><h2>replaceSelection's collapsing behavior</h2>
+
+<p>By
+default, <a href="manual.html#replaceSelection"><code>replaceSelection</code></a>
+would leave the newly inserted text selected. This is only rarely what
+you want, and also (slightly) more expensive in the new model, so the
+default was changed to <code>"end"</code>, meaning the old behavior
+must be explicitly specified by passing a second argument
+of <code>"around"</code>.</p>
+
+</section>
+
+<section id=changeEvent><h2>change event data</h2>
+
+<p>Rather than forcing client code to follow <code>next</code>
+pointers from one change object to the next, the library will now
+simply fire
+multiple <a href="manual.html#event_change"><code>"change"</code></a>
+events. Existing code will probably continue to work unmodified.</p>
+
+</section>
+
+<section id=showIfHidden><h2>showIfHidden option to line widgets</h2>
+
+<p>This option, which conceptually caused line widgets to be visible
+even if their line was hidden, was never really well-defined, and was
+buggy from the start. It would be a rather expensive feature, both in
+code complexity and run-time performance, to implement properly. It
+has been dropped entirely in 4.0.</p>
+
+</section>
+
+<section id=module><h2>Module loaders</h2>
+
+<p>All modules in the CodeMirror distribution are now wrapped in a
+shim function to make them compatible with both AMD
+(<a href="http://requirejs.org">requirejs</a>) and CommonJS (as used
+by <a href="http://nodejs.org/">node</a>
+and <a href="http://browserify.org/">browserify</a>) module loaders.
+When neither of these is present, they fall back to simply using the
+global <code>CodeMirror</code> variable.</p>
+
+<p>If you have a module loader present in your environment, CodeMirror
+will attempt to use it, and you might need to change the way you load
+CodeMirror modules.</p>
+
+</section>
+
+<section id=shareddata><h2>Mutating shared data structures</h2>
+
+<p>Data structures produced by the library should not be mutated
+unless explicitly allowed, in general. This is slightly more strict in
+4.0 than it was in earlier versions, which copied the position objects
+returned by <a href="manual.html#getCursor"><code>getCursor</code></a>
+for nebulous, historic reasons. In 4.0, mutating these
+objects <em>will</em> corrupt your editor's selection.</p>
+
+</section>
+
+<section id=deprecated><h2>Deprecated interfaces dropped</h2>
+
+<p>A few properties and methods that have been deprecated for a while
+are now gone. Most notably, the <code>onKeyEvent</code>
+and <code>onDragEvent</code> options (use the
+corresponding <a href="manual.html#event_dom">events</a> instead).</p>
+
+<p>Two silly methods, which were mostly there to stay close to the 0.x
+API, <code>setLine</code> and <code>removeLine</code> are now gone.
+Use the more
+flexible <a href="manual.html#replaceRange"><code>replaceRange</code></a>
+method instead.</p>
+
+<p>The long names for folding and completing functions
+(<code>CodeMirror.braceRangeFinder</code>, <code>CodeMirror.javascriptHint</code>,
+etc) are also gone
+(use <code>CodeMirror.fold.brace</code>, <code>CodeMirror.hint.javascript</code>).</p>
+
+<p>The <code>className</code> property in the return value
+of <a href="manual.html#getTokenAt"><code>getTokenAt</code></a>, which
+has been superseded by the <code>type</code> property, is also no
+longer present.</p>
+
+</section>

+   *  
+   *  $traversableInfo
+   *  @define mutability
+   *  @define traversableInfo
+   *  This is a base trait of all kinds of $mutability Scala collections. It
+   *  implements the behavior common to all collections, in terms of a method
+   *  `foreach` with signature:
+   * {{{
+   *     def foreach[U](f: Elem => U): Unit
+   * }}}
+   *  Collection classes mixing in this trait provide a concrete 
+   *  `foreach` method which traverses all the
+   *  elements contained in the collection, applying a given function to each.
+   *  They also need to provide a method `newBuilder`
+   *  which creates a builder for collections of the same kind.
+   *  
+   *  A traversable class might or might not have two properties: strictness
+   *  and orderedness. Neither is represented as a type.
+   *  
+   *  The instances of a strict collection class have all their elements
+   *  computed before they can be used as values. By contrast, instances of
+   *  a non-strict collection class may defer computation of some of their
+   *  elements until after the instance is available as a value.
+   *  A typical example of a non-strict collection class is a
+   *  <a href="../immutable/Stream.html" target="ContentFrame">
+   *  `scala.collection.immutable.Stream`</a>.
+   *  A more general class of examples are `TraversableViews`.
+   *  
+   *  If a collection is an instance of an ordered collection class, traversing
+   *  its elements with `foreach` will always visit elements in the
+   *  same order, even for different runs of the program. If the class is not
+   *  ordered, `foreach` can visit elements in different orders for

+
+    <p>It takes an optional mode configuration
+    option, <code>scriptTypes</code>, which can be used to add custom
+    behavior for specific <code>&lt;script type="..."></code> tags. If
+    given, it should hold an array of <code>{matches, mode}</code>
+    objects, where <code>matches</code> is a string or regexp that
+    matches the script type, and <code>mode</code> is
+    either <code>null</code>, for script types that should stay in
+    HTML mode, or a <a href="../../doc/manual.html#option_mode">mode
+    spec</a> corresponding to the mode that should be used for the
+    script.</p>

+        (<a href="typescript.html">demo</a>).</li>
+        <li><code>statementIndent</code> which (given a number) will

+
+Getting the Gist of Markdown's Formatting Syntax
+------------------------------------------------
+
+This page offers a brief overview of what it's like to use Markdown.
+The [syntax page] [s] provides complete, detailed documentation for
+every feature, but Markdown should be very easy to pick up simply by
+looking at a few examples of it in action. The examples on this page
+are written in a before/after style, showing example syntax and the
+HTML output produced by Markdown.
+
+It's also helpful to simply try Markdown out; the [Dingus] [d] is a
+web application that allows you type your own Markdown-formatted text
+and translate it to XHTML.
+
+**Note:** This document is itself written using Markdown; you
+can [see the source for it by adding '.text' to the URL] [src].
+
+  [s]: /projects/markdown/syntax  "Markdown Syntax"

+
+
+## Paragraphs, Headers, Blockquotes ##
+
+A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like
+a blank line -- a line containing nothing but spaces or tabs is
+considered blank.) Normal paragraphs should not be indented with
+spaces or tabs.
+
+Markdown offers two styles of headers: *Setext* and *atx*.
+Setext-style headers for `&lt;h1&gt;` and `&lt;h2&gt;` are created by
+"underlining" with equal signs (`=`) and hyphens (`-`), respectively.
+To create an atx-style header, you put 1-6 hash marks (`#`) at the
+beginning of the line -- the number of hashes equals the resulting
+HTML header level.
+
+Blockquotes are indicated using email-style '`&gt;`' angle brackets.
+
+Markdown:
+
+    A First Level Header
+    ====================
+    
+    A Second Level Header
+    ---------------------
+
+    Now is the time for all good men to come to
+    the aid of their country. This is just a
+    regular paragraph.
+
+    The quick brown fox jumped over the lazy
+    dog's back.
+    
+    ### Header 3
+
+    &gt; This is a blockquote.
+    &gt; 
+    &gt; This is the second paragraph in the blockquote.
+    &gt;
+    &gt; ## This is an H2 in a blockquote
+
+
+Output:
+
+    &lt;h1&gt;A First Level Header&lt;/h1&gt;
+    
+    &lt;h2&gt;A Second Level Header&lt;/h2&gt;
+    
+    &lt;p&gt;Now is the time for all good men to come to
+    the aid of their country. This is just a
+    regular paragraph.&lt;/p&gt;
+    
+    &lt;p&gt;The quick brown fox jumped over the lazy
+    dog's back.&lt;/p&gt;
+    
+    &lt;h3&gt;Header 3&lt;/h3&gt;
+    
+    &lt;blockquote&gt;
+        &lt;p&gt;This is a blockquote.&lt;/p&gt;
+        
+        &lt;p&gt;This is the second paragraph in the blockquote.&lt;/p&gt;
+        
+        &lt;h2&gt;This is an H2 in a blockquote&lt;/h2&gt;
+    &lt;/blockquote&gt;
+
+
+
+### Phrase Emphasis ###
+
+Markdown uses asterisks and underscores to indicate spans of emphasis.
+
+Markdown:
+
+    Some of these words *are emphasized*.
+    Some of these words _are emphasized also_.
+    
+    Use two asterisks for **strong emphasis**.
+    Or, if you prefer, __use two underscores instead__.
+
+Output:
+
+    &lt;p&gt;Some of these words &lt;em&gt;are emphasized&lt;/em&gt;.
+    Some of these words &lt;em&gt;are emphasized also&lt;/em&gt;.&lt;/p&gt;
+    
+    &lt;p&gt;Use two asterisks for &lt;strong&gt;strong emphasis&lt;/strong&gt;.
+    Or, if you prefer, &lt;strong&gt;use two underscores instead&lt;/strong&gt;.&lt;/p&gt;
+   
+
+
+## Lists ##
+
+Unordered (bulleted) lists use asterisks, pluses, and hyphens (`*`,
+`+`, and `-`) as list markers. These three markers are
+interchangable; this:
+
+    *   Candy.
+    *   Gum.
+    *   Booze.
+
+this:
+
+    +   Candy.
+    +   Gum.
+    +   Booze.
+
+and this:
+
+    -   Candy.
+    -   Gum.
+    -   Booze.
+
+all produce the same output:
+
+    &lt;ul&gt;
+    &lt;li&gt;Candy.&lt;/li&gt;
+    &lt;li&gt;Gum.&lt;/li&gt;
+    &lt;li&gt;Booze.&lt;/li&gt;
+    &lt;/ul&gt;
+
+Ordered (numbered) lists use regular numbers, followed by periods, as
+list markers:
+
+    1.  Red
+    2.  Green
+    3.  Blue
+
+Output:
+
+    &lt;ol&gt;
+    &lt;li&gt;Red&lt;/li&gt;
+    &lt;li&gt;Green&lt;/li&gt;
+    &lt;li&gt;Blue&lt;/li&gt;
+    &lt;/ol&gt;
+
+If you put blank lines between items, you'll get `&lt;p&gt;` tags for the
+list item text. You can create multi-paragraph list items by indenting
+the paragraphs by 4 spaces or 1 tab:
+
+    *   A list item.
+    
+        With multiple paragraphs.
+
+    *   Another item in the list.
+
+Output:
+
+    &lt;ul&gt;
+    &lt;li&gt;&lt;p&gt;A list item.&lt;/p&gt;
+    &lt;p&gt;With multiple paragraphs.&lt;/p&gt;&lt;/li&gt;
+    &lt;li&gt;&lt;p&gt;Another item in the list.&lt;/p&gt;&lt;/li&gt;
+    &lt;/ul&gt;
+    
+
+
+### Links ###
+
+Markdown supports two styles for creating links: *inline* and
+*reference*. With both styles, you use square brackets to delimit the
+text you want to turn into a link.
+
+Inline-style links use parentheses immediately after the link text.
+For example:
+
+    This is an [example link](http://example.com/).
+
+Output:
+
+    &lt;p&gt;This is an &lt;a href="http://example.com/"&gt;
+    example link&lt;/a&gt;.&lt;/p&gt;
+
+Optionally, you may include a title attribute in the parentheses:
+
+    This is an [example link](http://example.com/ "With a Title").
+
+Output:
+
+    &lt;p&gt;This is an &lt;a href="http://example.com/" title="With a Title"&gt;
+    example link&lt;/a&gt;.&lt;/p&gt;
+
+Reference-style links allow you to refer to your links by names, which
+you define elsewhere in your document:
+
+    I get 10 times more traffic from [Google][1] than from
+    [Yahoo][2] or [MSN][3].
+
+    [1]: http://google.com/        "Google"
+    [2]: http://search.yahoo.com/  "Yahoo Search"
+    [3]: http://search.msn.com/    "MSN Search"
+
+Output:
+
+    &lt;p&gt;I get 10 times more traffic from &lt;a href="http://google.com/"
+    title="Google"&gt;Google&lt;/a&gt; than from &lt;a href="http://search.yahoo.com/"
+    title="Yahoo Search"&gt;Yahoo&lt;/a&gt; or &lt;a href="http://search.msn.com/"
+    title="MSN Search"&gt;MSN&lt;/a&gt;.&lt;/p&gt;
+
+The title attribute is optional. Link names may contain letters,
+numbers and spaces, but are *not* case sensitive:
+
+    I start my morning with a cup of coffee and
+    [The New York Times][NY Times].
+
+    [ny times]: http://www.nytimes.com/
+
+Output:
+
+    &lt;p&gt;I start my morning with a cup of coffee and
+    &lt;a href="http://www.nytimes.com/"&gt;The New York Times&lt;/a&gt;.&lt;/p&gt;
+
+
+### Images ###
+
+Image syntax is very much like link syntax.
+
+Inline (titles are optional):
+
+    ![alt text](/path/to/img.jpg "Title")
+
+Reference-style:
+
+    ![alt text][id]
+
+    [id]: /path/to/img.jpg "Title"
+
+Both of the above examples produce the same output:
+
+    &lt;img src="/path/to/img.jpg" alt="alt text" title="Title" /&gt;
+
+
+
+### Code ###
+
+In a regular paragraph, you can create code span by wrapping text in
+backtick quotes. Any ampersands (`&amp;`) and angle brackets (`&lt;` or
+`&gt;`) will automatically be translated into HTML entities. This makes
+it easy to use Markdown to write about HTML example code:
+
+    I strongly recommend against using any `&lt;blink&gt;` tags.
+
+    I wish SmartyPants used named entities like `&amp;mdash;`
+    instead of decimal-encoded entites like `&amp;#8212;`.
+
+Output:
+
+    &lt;p&gt;I strongly recommend against using any
+    &lt;code&gt;&amp;lt;blink&amp;gt;&lt;/code&gt; tags.&lt;/p&gt;
+    
+    &lt;p&gt;I wish SmartyPants used named entities like
+    &lt;code&gt;&amp;amp;mdash;&lt;/code&gt; instead of decimal-encoded
+    entites like &lt;code&gt;&amp;amp;#8212;&lt;/code&gt;.&lt;/p&gt;
+
+
+To specify an entire block of pre-formatted code, indent every line of
+the block by 4 spaces or 1 tab. Just like with code spans, `&amp;`, `&lt;`,
+and `&gt;` characters will be escaped automatically.
+
+Markdown:
+
+    If you want your page to validate under XHTML 1.0 Strict,
+    you've got to put paragraph tags in your blockquotes:
+
+        &lt;blockquote&gt;
+            &lt;p&gt;For example.&lt;/p&gt;
+        &lt;/blockquote&gt;
+
+Output:
+
+    &lt;p&gt;If you want your page to validate under XHTML 1.0 Strict,
+    you've got to put paragraph tags in your blockquotes:&lt;/p&gt;
+    
+    &lt;pre&gt;&lt;code&gt;&amp;lt;blockquote&amp;gt;
+        &amp;lt;p&amp;gt;For example.&amp;lt;/p&amp;gt;
+    &amp;lt;/blockquote&amp;gt;

+/ utilities to quickly load a csv file - for more exhaustive analysis of the csv contents see csvguess.q
+/ 2009.09.20 - updated to match latest csvguess.q 
+
+/ .csv.colhdrs[file] - return a list of colhdrs from file
+/ info:.csv.info[file] - return a table of information about the file
+/ columns are: 
+/	c - column name; ci - column index; t - load type; mw - max width; 
+/	dchar - distinct characters in values; rule - rule that caught the type
+/	maybe - needs checking, _could_ be say a date, but perhaps just a float?
+/ .csv.info0[file;onlycols] - like .csv.info except that it only analyses <onlycols>
+/ example:
+/	info:.csv.info0[file;(.csv.colhdrs file)like"*price"]
+/	info:.csv.infolike[file;"*price"]
+/	show delete from info where t=" "
+/ .csv.data[file;info] - use the info from .csv.info to read the data
+/ .csv.data10[file;info] - like .csv.data but only returns the first 10 rows
+/ bulkload[file;info] - bulk loads file into table DATA (which must be already defined :: DATA:() )
+/ .csv.read[file]/read10[file] - for when you don't care about checking/tweaking the <info> before reading

+<h2>reStructuredText mode</h2>
+<form><textarea id="code" name="code">
+.. This is an excerpt from Sphinx documentation: http://sphinx.pocoo.org/_sources/rest.txt
+
+.. highlightlang:: rest
+
+.. _rst-primer:
+
+reStructuredText Primer
+=======================
+
+This section is a brief introduction to reStructuredText (reST) concepts and
+syntax, intended to provide authors with enough information to author documents
+productively.  Since reST was designed to be a simple, unobtrusive markup
+language, this will not take too long.
+
+.. seealso::
+
+   The authoritative `reStructuredText User Documentation
+   &lt;http://docutils.sourceforge.net/rst.html&gt;`_.  The "ref" links in this
+   document link to the description of the individual constructs in the reST
+   reference.
+
+
+Paragraphs
+----------
+
+The paragraph (:duref:`ref &lt;paragraphs&gt;`) is the most basic block in a reST
+document.  Paragraphs are simply chunks of text separated by one or more blank
+lines.  As in Python, indentation is significant in reST, so all lines of the
+same paragraph must be left-aligned to the same level of indentation.
+
+
+.. _inlinemarkup:
+
+Inline markup
+-------------
+
+The standard reST inline markup is quite simple: use
+
+* one asterisk: ``*text*`` for emphasis (italics),
+* two asterisks: ``**text**`` for strong emphasis (boldface), and
+* backquotes: ````text```` for code samples.
+
+If asterisks or backquotes appear in running text and could be confused with
+inline markup delimiters, they have to be escaped with a backslash.
+
+Be aware of some restrictions of this markup:
+
+* it may not be nested,
+* content may not start or end with whitespace: ``* text*`` is wrong,
+* it must be separated from surrounding text by non-word characters.  Use a
+  backslash escaped space to work around that: ``thisis\ *one*\ word``.
+
+These restrictions may be lifted in future versions of the docutils.
+
+reST also allows for custom "interpreted text roles"', which signify that the
+enclosed text should be interpreted in a specific way.  Sphinx uses this to
+provide semantic markup and cross-referencing of identifiers, as described in
+the appropriate section.  The general syntax is ``:rolename:`content```.
+
+Standard reST provides the following roles:
+
+* :durole:`emphasis` -- alternate spelling for ``*emphasis*``
+* :durole:`strong` -- alternate spelling for ``**strong**``
+* :durole:`literal` -- alternate spelling for ````literal````
+* :durole:`subscript` -- subscript text
+* :durole:`superscript` -- superscript text
+* :durole:`title-reference` -- for titles of books, periodicals, and other
+  materials
+
+See :ref:`inline-markup` for roles added by Sphinx.
+
+
+Lists and Quote-like blocks
+---------------------------
+
+List markup (:duref:`ref &lt;bullet-lists&gt;`) is natural: just place an asterisk at
+the start of a paragraph and indent properly.  The same goes for numbered lists;
+they can also be autonumbered using a ``#`` sign::
+
+   * This is a bulleted list.
+   * It has two items, the second
+     item uses two lines.
+
+   1. This is a numbered list.
+   2. It has two items too.
+
+   #. This is a numbered list.
+   #. It has two items too.
+
+
+Nested lists are possible, but be aware that they must be separated from the
+parent list items by blank lines::
+
+   * this is
+   * a list
+
+     * with a nested list
+     * and some subitems
+
+   * and here the parent list continues
+
+Definition lists (:duref:`ref &lt;definition-lists&gt;`) are created as follows::
+
+   term (up to a line of text)
+      Definition of the term, which must be indented
+
+      and can even consist of multiple paragraphs
+
+   next term
+      Description.
+
+Note that the term cannot have more than one line of text.
+
+Quoted paragraphs (:duref:`ref &lt;block-quotes&gt;`) are created by just indenting
+them more than the surrounding paragraphs.
+
+Line blocks (:duref:`ref &lt;line-blocks&gt;`) are a way of preserving line breaks::
+
+   | These lines are
+   | broken exactly like in
+   | the source file.
+
+There are also several more special blocks available:
+
+* field lists (:duref:`ref &lt;field-lists&gt;`)
+* option lists (:duref:`ref &lt;option-lists&gt;`)
+* quoted literal blocks (:duref:`ref &lt;quoted-literal-blocks&gt;`)
+* doctest blocks (:duref:`ref &lt;doctest-blocks&gt;`)
+
+
+Source Code
+-----------
+
+Literal code blocks (:duref:`ref &lt;literal-blocks&gt;`) are introduced by ending a
+paragraph with the special marker ``::``.  The literal block must be indented
+(and, like all paragraphs, separated from the surrounding ones by blank lines)::
+
+   This is a normal text paragraph. The next paragraph is a code sample::
+
+      It is not processed in any way, except
+      that the indentation is removed.
+
+      It can span multiple lines.
+
+   This is a normal text paragraph again.
+
+The handling of the ``::`` marker is smart:
+
+* If it occurs as a paragraph of its own, that paragraph is completely left
+  out of the document.
+* If it is preceded by whitespace, the marker is removed.
+* If it is preceded by non-whitespace, the marker is replaced by a single
+  colon.
+
+That way, the second sentence in the above example's first paragraph would be
+rendered as "The next paragraph is a code sample:".
+
+
+.. _rst-tables:
+
+Tables
+------
+
+Two forms of tables are supported.  For *grid tables* (:duref:`ref
+&lt;grid-tables&gt;`), you have to "paint" the cell grid yourself.  They look like
+this::
+
+   +------------------------+------------+----------+----------+
+   | Header row, column 1   | Header 2   | Header 3 | Header 4 |
+   | (header rows optional) |            |          |          |
+   +========================+============+==========+==========+
+   | body row 1, column 1   | column 2   | column 3 | column 4 |
+   +------------------------+------------+----------+----------+
+   | body row 2             | ...        | ...      |          |
+   +------------------------+------------+----------+----------+
+
+*Simple tables* (:duref:`ref &lt;simple-tables&gt;`) are easier to write, but
+limited: they must contain more than one row, and the first column cannot
+contain multiple lines.  They look like this::
+
+   =====  =====  =======
+   A      B      A and B
+   =====  =====  =======
+   False  False  False
+   True   False  False
+   False  True   False
+   True   True   True
+   =====  =====  =======
+
+
+Hyperlinks
+----------
+
+External links
+^^^^^^^^^^^^^^
+
+Use ```Link text &lt;http://example.com/&gt;`_`` for inline web links.  If the link
+text should be the web address, you don't need special markup at all, the parser
+finds links and mail addresses in ordinary text.
+
+You can also separate the link and the target definition (:duref:`ref
+&lt;hyperlink-targets&gt;`), like this::
+
+   This is a paragraph that contains `a link`_.
+
+   .. _a link: http://example.com/
+
+
+Internal links
+^^^^^^^^^^^^^^
+
+Internal linking is done via a special reST role provided by Sphinx, see the
+section on specific markup, :ref:`ref-role`.
+
+
+Sections
+--------
+
+Section headers (:duref:`ref &lt;sections&gt;`) are created by underlining (and
+optionally overlining) the section title with a punctuation character, at least
+as long as the text::
+
+   =================
+   This is a heading
+   =================
+
+Normally, there are no heading levels assigned to certain characters as the
+structure is determined from the succession of headings.  However, for the
+Python documentation, this convention is used which you may follow:
+
+* ``#`` with overline, for parts
+* ``*`` with overline, for chapters
+* ``=``, for sections
+* ``-``, for subsections
+* ``^``, for subsubsections
+* ``"``, for paragraphs
+
+Of course, you are free to use your own marker characters (see the reST
+documentation), and use a deeper nesting level, but keep in mind that most
+target formats (HTML, LaTeX) have a limited supported nesting depth.
+
+
+Explicit Markup
+---------------
+
+"Explicit markup" (:duref:`ref &lt;explicit-markup-blocks&gt;`) is used in reST for
+most constructs that need special handling, such as footnotes,
+specially-highlighted paragraphs, comments, and generic directives.
+
+An explicit markup block begins with a line starting with ``..`` followed by
+whitespace and is terminated by the next paragraph at the same level of
+indentation.  (There needs to be a blank line between explicit markup and normal
+paragraphs.  This may all sound a bit complicated, but it is intuitive enough
+when you write it.)
+
+
+.. _directives:
+
+Directives
+----------
+
+A directive (:duref:`ref &lt;directives&gt;`) is a generic block of explicit markup.
+Besides roles, it is one of the extension mechanisms of reST, and Sphinx makes
+heavy use of it.
+
+Docutils supports the following directives:
+
+* Admonitions: :dudir:`attention`, :dudir:`caution`, :dudir:`danger`,
+  :dudir:`error`, :dudir:`hint`, :dudir:`important`, :dudir:`note`,
+  :dudir:`tip`, :dudir:`warning` and the generic :dudir:`admonition`.
+  (Most themes style only "note" and "warning" specially.)
+
+* Images:
+
+  - :dudir:`image` (see also Images_ below)
+  - :dudir:`figure` (an image with caption and optional legend)
+
+* Additional body elements:
+
+  - :dudir:`contents` (a local, i.e. for the current file only, table of
+    contents)
+  - :dudir:`container` (a container with a custom class, useful to generate an
+    outer ``&lt;div&gt;`` in HTML)
+  - :dudir:`rubric` (a heading without relation to the document sectioning)
+  - :dudir:`topic`, :dudir:`sidebar` (special highlighted body elements)
+  - :dudir:`parsed-literal` (literal block that supports inline markup)
+  - :dudir:`epigraph` (a block quote with optional attribution line)
+  - :dudir:`highlights`, :dudir:`pull-quote` (block quotes with their own
+    class attribute)
+  - :dudir:`compound` (a compound paragraph)
+
+* Special tables:
+
+  - :dudir:`table` (a table with title)
+  - :dudir:`csv-table` (a table generated from comma-separated values)
+  - :dudir:`list-table` (a table generated from a list of lists)
+
+* Special directives:
+
+  - :dudir:`raw` (include raw target-format markup)
+  - :dudir:`include` (include reStructuredText from another file)
+    -- in Sphinx, when given an absolute include file path, this directive takes
+    it as relative to the source directory
+  - :dudir:`class` (assign a class attribute to the next element) [1]_
+
+* HTML specifics:
+
+  - :dudir:`meta` (generation of HTML ``&lt;meta&gt;`` tags)
+  - :dudir:`title` (override document title)
+
+* Influencing markup:
+
+  - :dudir:`default-role` (set a new default role)
+  - :dudir:`role` (create a new role)
+
+  Since these are only per-file, better use Sphinx' facilities for setting the
+  :confval:`default_role`.
+
+Do *not* use the directives :dudir:`sectnum`, :dudir:`header` and
+:dudir:`footer`.
+
+Directives added by Sphinx are described in :ref:`sphinxmarkup`.
+
+Basically, a directive consists of a name, arguments, options and content. (Keep
+this terminology in mind, it is used in the next chapter describing custom
+directives.)  Looking at this example, ::
+
+   .. function:: foo(x)
+                 foo(y, z)
+      :module: some.module.name
+
+      Return a line of text input from the user.
+
+``function`` is the directive name.  It is given two arguments here, the
+remainder of the first line and the second line, as well as one option
+``module`` (as you can see, options are given in the lines immediately following
+the arguments and indicated by the colons).  Options must be indented to the
+same level as the directive content.
+
+The directive content follows after a blank line and is indented relative to the
+directive start.
+
+
+Images
+------
+
+reST supports an image directive (:dudir:`ref &lt;image&gt;`), used like so::
+
+   .. image:: gnu.png
+      (options)
+
+When used within Sphinx, the file name given (here ``gnu.png``) must either be
+relative to the source file, or absolute which means that they are relative to
+the top source directory.  For example, the file ``sketch/spam.rst`` could refer
+to the image ``images/spam.png`` as ``../images/spam.png`` or
+``/images/spam.png``.
+
+Sphinx will automatically copy image files over to a subdirectory of the output
+directory on building (e.g. the ``_static`` directory for HTML output.)
+
+Interpretation of image size options (``width`` and ``height``) is as follows:
+if the size has no unit or the unit is pixels, the given size will only be
+respected for output channels that support pixels (i.e. not in LaTeX output).
+Other units (like ``pt`` for points) will be used for HTML and LaTeX output.
+
+Sphinx extends the standard docutils behavior by allowing an asterisk for the
+extension::
+
+   .. image:: gnu.*
+
+Sphinx then searches for all images matching the provided pattern and determines
+their type.  Each builder then chooses the best image out of these candidates.
+For instance, if the file name ``gnu.*`` was given and two files :file:`gnu.pdf`
+and :file:`gnu.png` existed in the source tree, the LaTeX builder would choose
+the former, while the HTML builder would prefer the latter.
+
+.. versionchanged:: 0.4
+   Added the support for file names ending in an asterisk.
+
+.. versionchanged:: 0.6
+   Image paths can now be absolute.
+
+
+Footnotes
+---------
+
+For footnotes (:duref:`ref &lt;footnotes&gt;`), use ``[#name]_`` to mark the footnote
+location, and add the footnote body at the bottom of the document after a
+"Footnotes" rubric heading, like so::
+
+   Lorem ipsum [#f1]_ dolor sit amet ... [#f2]_
+
+   .. rubric:: Footnotes
+
+   .. [#f1] Text of the first footnote.
+   .. [#f2] Text of the second footnote.
+
+You can also explicitly number the footnotes (``[1]_``) or use auto-numbered
+footnotes without names (``[#]_``).
+
+
+Citations
+---------
+
+Standard reST citations (:duref:`ref &lt;citations&gt;`) are supported, with the
+additional feature that they are "global", i.e. all citations can be referenced
+from all files.  Use them like so::
+
+   Lorem ipsum [Ref]_ dolor sit amet.
+
+   .. [Ref] Book or article reference, URL or whatever.
+
+Citation usage is similar to footnote usage, but with a label that is not
+numeric or begins with ``#``.
+
+
+Substitutions
+-------------
+
+reST supports "substitutions" (:duref:`ref &lt;substitution-definitions&gt;`), which
+are pieces of text and/or markup referred to in the text by ``|name|``.  They
+are defined like footnotes with explicit markup blocks, like this::
+
+   .. |name| replace:: replacement *text*
+
+or this::
+
+   .. |caution| image:: warning.png
+                :alt: Warning!
+
+See the :duref:`reST reference for substitutions &lt;substitution-definitions&gt;`
+for details.
+
+If you want to use some substitutions for all documents, put them into
+:confval:`rst_prolog` or put them into a separate file and include it into all
+documents you want to use them in, using the :rst:dir:`include` directive.  (Be
+sure to give the include file a file name extension differing from that of other
+source files, to avoid Sphinx finding it as a standalone document.)
+
+Sphinx defines some default substitutions, see :ref:`default-substitutions`.
+
+
+Comments
+--------
+
+Every explicit markup block which isn't a valid markup construct (like the
+footnotes above) is regarded as a comment (:duref:`ref &lt;comments&gt;`).  For
+example::
+
+   .. This is a comment.
+
+You can indent text after a comment start to form multiline comments::
+
+   ..
+      This whole indented block
+      is a comment.
+
+      Still in the comment.
+
+
+Source encoding
+---------------
+
+Since the easiest way to include special characters like em dashes or copyright
+signs in reST is to directly write them as Unicode characters, one has to
+specify an encoding.  Sphinx assumes source files to be encoded in UTF-8 by
+default; you can change this with the :confval:`source_encoding` config value.
+
+
+Gotchas
+-------
+
+There are some problems one commonly runs into while authoring reST documents:
+
+* **Separation of inline markup:** As said above, inline markup spans must be
+  separated from the surrounding text by non-word characters, you have to use a
+  backslash-escaped space to get around that.  See `the reference
+  &lt;http://docutils.sf.net/docs/ref/rst/restructuredtext.html#inline-markup&gt;`_
+  for the details.
+
+* **No nested inline markup:** Something like ``*see :func:`foo`*`` is not
+  possible.
+
+
+.. rubric:: Footnotes
+
+.. [1] When the default domain contains a :rst:dir:`class` directive, this directive
+       will be shadowed.  Therefore, Sphinx re-exports it as :rst:dir:`rst-class`.

+
+  keywords:

+  functions:
+    A list of function names you want to be highlighted.
+  builtin:
+    A list of builtin types you want to be highlighted (if you want types to be of class "builtin" instead of "keyword").
+  operatorChars:
+    All characters that must be handled as operators.
+  client:
+    Commands parsed and executed by the client (not the server).
+  support:
+    A list of supported syntaxes which are not common, but are supported by more than 1 DBMS.
+    * ODBCdotTable: .tableName
+    * zerolessFloat: .1
+    * doubleQuote
+    * nCharCast: N'string'
+    * charsetCast: _utf8'string'
+    * commentHash: use # char for comments
+    * commentSlashSlash: use // for comments
+    * commentSpaceRequired: require a space after -- for comments
+  atoms:
+    Keywords that must be highlighted as atoms,. Some DBMS's support more atoms than others:
+    UNKNOWN, INFINITY, UNDERFLOW, NaN...
+  dateSQL:
+    Used for date/time SQL standard syntax, because not all DBMS's support same temporal types.

+* {{{<<macroName>>}}} calls the respective [[macro|Macros]]
+* To hide text within a tiddler so that it is not displayed, it can be wrapped in {{{/%}}} and {{{%/}}}.<br/>This can be a useful trick for hiding drafts or annotating complex markup.
+* To prevent wiki markup from taking effect for a particular section, that section can be enclosed in three double quotes: e.g. {{{"""WikiWord"""}}}.

+    <p>The XML mode supports two configuration parameters:</p>
+    <dl>
+      <dt><code>htmlMode (boolean)</code></dt>
+      <dd>This switches the mode to parse HTML instead of XML. This
+      means attributes do not have to be quoted, and some elements
+      (such as <code>br</code>) do not require a closing tag.</dd>
+      <dt><code>alignCDATA (boolean)</code></dt>
+      <dd>Setting this to true will force the opening tag of CDATA
+      blocks to not be indented.</dd>

+    import module namespace json=&quot;http://marklogic.com/json&quot; at &quot;json.xqy&quot;;

+  Sample transformations:
+  &lt;pre&gt;
+  &amp;lt;e/&amp;gt; becomes {&quot;e&quot;:null}
+  &amp;lt;e&amp;gt;text&amp;lt;/e&amp;gt; becomes {&quot;e&quot;:&quot;text&quot;}

+  &lt;/pre&gt;
+  &lt;p/&gt;
+  Namespace URIs are ignored.  Namespace prefixes are included in the JSON name.
+  &lt;p/&gt;
+  Attributes are ignored, except for the special attribute @array=&quot;true&quot; that
+  indicates the JSON serialization should write the node, even if single, as an
+  array, and the attribute @type that can be set to &quot;boolean&quot; or &quot;number&quot; to
+  dictate the value should be written as that type (unquoted).  There's also
+  an @quote attribute that when set to true writes the inner content as text
+  rather than as structured JSON, useful for sending some XHTML over the
+  wire.
+  &lt;p/&gt;
+  Text nodes within mixed content are ignored.

+  // advancing the input stream and returning an AST node. Precedence
+  // of constructs (for example, the fact that `!x[1]` means `!(x[1])`
+  // instead of `(!x)[1]` is handled by the fact that the parser
+  // function that parses unary prefix operators is called first, and
+  // in turn calls the function that parses `[]` subscripts — that
+  // way, it'll receive the node for `x[1]` already parsed, and wraps
+  // *that* in the unary operator node.
+  //
+  // Acorn uses an [operator precedence parser][opp] to handle binary
+  // operator precedence, because it is much more compact than using
+  // the technique outlined above, which uses different, nesting
+  // functions to specify precedence, for all of the ten binary
+  // precedence levels that JavaScript defines.

+/**
+ * Helper to test CodeMirror highlighting modes. It pretty prints output of the
+ * highlighter and can check against expected styles.
+ *
+ * Mode tests are registered by calling test.mode(testName, mode,
+ * tokens), where mode is a mode object as returned by
+ * CodeMirror.getMode, and tokens is an array of lines that make up
+ * the test.
+ *
+ * These lines are strings, in which styled stretches of code are
+ * enclosed in brackets `[]`, and prefixed by their style. For
+ * example, `[keyword if]`. Brackets in the code itself must be
+ * duplicated to prevent them from being interpreted as token
+ * boundaries. For example `a[[i]]` for `a[i]`. If a token has
+ * multiple styles, the styles must be separated by ampersands, for
+ * example `[tag&error </hmtl>]`.
+ *
+ * See the test.js files in the css, markdown, gfm, and stex mode
+ * directories for examples.

+/**
+ * Sets the type of metadata to use. Metadata is encoded in JSON, and each property
+ * in the JSON will become a property of the element itself.
+ *
+ * There are three supported types of metadata storage:
+ *
+ *   attr:  Inside an attribute. The name parameter indicates *which* attribute.
+ *          
+ *   class: Inside the class attribute, wrapped in curly braces: { }
+ *   
+ *   elem:  Inside a child element (e.g. a script tag). The
+ *          name parameter indicates *which* element.
+ *          
+ * The metadata for an element is loaded the first time the element is accessed via jQuery.
+ *
+ * As a result, you can define the metadata type, use $(expr) to load the metadata into the elements
+ * matched by expr, then redefine the metadata type and run another $(expr) for other elements.
+ * 
+ * @name $.metadata.setType
+ *
+ * @example <p id="one" class="some_class {item_id: 1, item_label: 'Label'}">This is a p</p>
+ * @before $.metadata.setType("class")
+ * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
+ * @desc Reads metadata from the class attribute
+ * 
+ * @example <p id="one" class="some_class" data="{item_id: 1, item_label: 'Label'}">This is a p</p>
+ * @before $.metadata.setType("attr", "data")
+ * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
+ * @desc Reads metadata from a "data" attribute
+ * 
+ * @example <p id="one" class="some_class"><script>{item_id: 1, item_label: 'Label'}</script>This is a p</p>
+ * @before $.metadata.setType("elem", "script")
+ * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
+ * @desc Reads metadata from a nested script element
+ * 
+ * @param String type The encoding type
+ * @param String name The name of the attribute to be used to get metadata (optional)
+ * @cat Plugins/Metadata
+ * @descr Sets the type of encoding to be used when loading metadata for the first time
+ * @type undefined
