Due to historical reasons, the code is in subfolder "1". With SVN removal, we place the code back and remove the annoying "1" folder.

<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>

<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();
