8 ==========================
10 If no interest is expressed for a feature that may required a considerable
11 amount of effort to implement, it may get endlessly delayed. Do not be
12 afraid to cast your vote for the next feature to be implemented!
19 - Release candidate, because of the major changes
22 - Update French translation of README
25 - Get everything into configuration objects (filters, I'm looking at you)
26 - Factor out command line parser into its own class, and unit test it
29 - Properly integrate new ConfigSchema system into configdoc. DESCRIPTIONS
30 ARE CURRENTLY BROKEN AND NEED TO BE FIXED!!! (Configdoc
31 should directly read the configuration files, or at the very least should
32 not use static functions)
33 - Have configdoc use version and deprecated information (hide deprecated
35 - Implement source code sniffing for configdoc, so we can easily figure out
36 which files use what configuration (we'll rely on the $config convention)
39 - Factor demo.php into a set of Printer classes, and then create a stub
40 file for users here (inside the actual HTML Purifier library)
41 - Support exporting configuration, so users can easily tweak settings
42 in the demo, and then copy-paste into their own setup
45 - Style attribute height/width limiting for images
46 - Easy way to blacklist elements and attributes
47 - Investigate iconv error emitting
48 - Investigate UTF-8 optimization <http://htmlpurifier.org/phorum/read.php?3,1496>
49 - Figure out what to do about target="" and name="", since they show up so often
50 - Update htmLawed comparison
55 3.2 release [Error'ed]
56 # Error logging for filtering/cleanup procedures
57 - XSS-attempt detection
59 3.3 release [Do What I Mean, Not What I Say]
60 # Additional support for poorly written HTML
61 - Microsoft Word HTML cleaning (i.e. MsoNormal, but research essential!)
62 - Friendly strict handling of <address> (block -> <br>)
63 - Remove redundant tags, ex. <u><u>Underlined</u></u>. Implementation notes:
64 1. Analyzing which tags to remove duplicants
65 2. Ensure attributes are merged into the parent tag
66 3. Extend the tag exclusion system to specify whether or not the
67 contents should be dropped or not (currently, there's code that could do
68 something like this if it didn't drop the inner text too.)
69 - Remove <span> tags that don't do anything (no attributes)
70 - Remove empty inline tags<i></i>
71 - Append something to duplicate IDs so they're still usable (impl. note: the
72 dupe detector would also need to detect the suffix as well)
73 - Externalize inline CSS to promote clean HTML
75 3.4 release [It's All About Trust] (floating)
76 # Implement untrusted, dangerous elements/attributes
77 - Objects and Forms are especially wanted
78 # Implement IDREF support (harder than it seems, since you cannot have
79 IDREFs to non-existent IDs)
80 # Frameset XHTML 1.0 and HTML 4.01 doctypes
82 4.0 release [Beyond HTML]
83 # Legit token based CSS parsing (will require revamping almost every
84 AttrDef class). Probably will use CSSTidy class
85 # More control over allowed CSS properties (maybe modularize it in the
88 - Standardize token armor for all areas of processing
89 - Convert RTL/LTR override characters to <bdo> tags, or vice versa on demand.
90 Also, enable disabling of directionality
91 - Table of Contents generation (XHTML Compiler might be reusable)
93 5.0 release [To XML and Beyond]
94 - Extended HTML capabilities based on namespacing and tag transforms (COMPLEX)
95 - Hooks for adding custom processors to custom namespaced tags and
96 attributes, offer default implementation
97 - Lots of documentation and samples
100 - More refactoring to take advantage of PHP5's facilities
101 - Lots of profiling, make it faster!
102 - Plugins for major CMSes (COMPLEX)
104 - more! (look for ones that use WYSIWYGs)
105 - Complete basic smoketests
109 - Syntax highlighting with <pre> and possibly <?php
110 - Look at http://drupal.org/project/Modules/category/63 for ideas
112 Unknown release (on a scratch-an-itch basis)
113 # CHMOD install script for PEAR installs
114 ? Have 'lang' attribute be checked against official lists, achieved by
115 encoding all characters that have string entity equivalents
116 - Abstract ChildDef_BlockQuote to work with all elements that only
117 allow blocks in them, required or optional
118 - Reorganize Unit Tests
119 - Advanced URI filtering schemes (see docs/proposal-new-directives.txt)
120 - Implement lenient <ruby> child validation
121 - Explain how to use HTML Purifier in non-PHP languages / create
122 a simple command line stub (or complicated?)
123 - Fixes for Firefox's inability to handle COL alignment props (Bug 915)
124 - Automatically add non-breaking spaces to empty table cells when
125 empty-cells:show is applied to have compatibility with Internet Explorer
126 - Distinguish between default settings and explicitly set settings, so
127 configurations can be merged
128 - Nested configuration namespaces
129 - Allow scoped="scoped" attribute in <style> tags; may be troublesome
130 because regular CSS has no way of uniquely identifying nodes, so we'd
137 - Non-lossy smart alternate character encoding transformations (unless
139 - Pretty-printing HTML: users can use Tidy on the output on entire page
140 - Native content compression, whitespace stripping (don't rely on Tidy, make
141 sure we don't remove from <pre> or related tags): use gzip if this is
