- XSS-attempt detection--certain errors are flagged XSS-like
- Append something to duplicate IDs so they're still usable (impl. note: the
dupe detector would also need to detect the suffix as well)
6.0 release [Beyond HTML]
# Legit token based CSS parsing (will require revamping almost every
AttrDef class). Probably will use CSSTidy
# More control over allowed CSS properties using a modularization
# IRI support (this includes IDN)
- Standardize token armor for all areas of processing
7.0 release [To XML and Beyond]
- Extended HTML capabilities based on namespacing and tag transforms (COMPLEX)
- Hooks for adding custom processors to custom namespaced tags and
attributes, offer default implementation
- Lots of documentation and samples
Ongoing
- More refactoring to take advantage of PHP5's facilities
- Refactor unit tests into lots of test methods
- Plugins for major CMSes (COMPLEX)
- phpBB
- Also, a FAQ for extension writers with HTML Purifier
AutoFormat
- Smileys
- Syntax highlighting (with GeSHi) with and possibly tags; may be troublesome
because regular CSS has no way of uniquely identifying nodes, so we'd
have to generate IDs
- Explain how to use HTML Purifier in non-PHP languages / create
a simple command line stub (or complicated?)
- Fixes for Firefox's inability to handle COL alignment props (Bug 915)
- Automatically add non-breaking spaces to empty table cells when
empty-cells:show is applied to have compatibility with Internet Explorer
- Table of Contents generation (XHTML Compiler might be reusable). May also
be out-of-band information.
- Full set of color keywords. Also, a way to add onto them without
finalizing the configuration object.
- Write a var_export and memcached DefinitionCache - Denis
- Built-in support for target="_blank" on all external links
- Convert RTL/LTR override characters to tags, or vice versa on demand.
Also, enable disabling of directionality
? Externalize inline CSS to promote clean HTML, proposed by Sander Tekelenburg
? Remove redundant tags, ex. Underlined. Implementation notes:
1. Analyzing which tags to remove duplicants
2. Ensure attributes are merged into the parent tag
3. Extend the tag exclusion system to specify whether or not the
contents should be dropped or not (currently, there's code that could do
something like this if it didn't drop the inner text too.)
? Make AutoParagraph also support paragraph-izing double
tags, and not
just double newlines. This is kind of tough to do in the current framework,
though, and might be reasonably approximated by search replacing double
s
with newlines before running it through HTML Purifier.
Maintenance related (slightly boring)
# CHMOD install script for PEAR installs
! Factor out command line parser into its own class, and unit test it
- Reduce size of internal data-structures (esp. HTMLDefinition)
- Allow merging configurations. Thus,
a -> b -> default
c -> d -> default
becomes
a -> b -> c -> d -> default
Maybe allow more fine-grained tuning of this behavior. Alternatively,
encourage people to use short plist depths before building them up.
- Time PHPT tests
ChildDef related (very boring)
- Abstract ChildDef_BlockQuote to work with all elements that only
allow blocks in them, required or optional
- Implement lenient child validation
Wontfix
- Non-lossy smart alternate character encoding transformations (unless
patch provided)
- Pretty-printing HTML: users can use Tidy on the output on entire page
- Native content compression, whitespace stripping: use gzip if this is
really important
