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 - Test HTMLPurifier.auto.php, HTMLPurifier.includes.php, and combinations
20 of the two. This is related to standalone in tests/index.php. This should use
21 semi-automated smoketests using PHPT style files (probably should be part
22 of SimpleTest framework). These tests can be further extended to work for
23 many of our other smoketests.
24 - Release candidate, because of the major changes
25 - Move utility classes for ConfigSchema into HTML Purifier itself: they're
29 - Document new methods of including the library (probably can go in INSTALL)
30 - Document new ConfigSchema setup and format; dev-includes.txt is a base
31 but we need it in HTML
32 - Update French translation of README
33 - Document which scripts need to be called when a change is made
34 - Document that standalone doesn't load autoload by default, so you need
35 to include HTMLPurifier.autoload.php after it
38 - Get everything into configuration objects (filters, I'm looking at you)
39 - Factor generate-schema-cache.php into a class, so that the maintenance script
40 is as small as possible
41 - Factor out command line parser into its own class
42 - Optimize ConfigSchema by only caching things necessary for runtime
45 - Properly integrate new ConfigSchema system into configdoc (Configdoc
46 should directly read the configuration files, or at the very least should
47 not use static functions)
48 - Reduce code duplication between Serializer and Adapter/ReverseAdapter
49 (we probably want to use ReverseAdapter for the long haul)
50 - Have configdoc use version and deprecated information (hide deprecated
52 - Implement file sniffing for configdoc, so we can easily figure out
53 which files use what configuration
56 - Rename merge-library.php script
57 - Create "super" script which performs all regeneration actions
58 - Remove all includes from unit tests, and remove blanks/ folder and generation
59 - Simplify merge library script by removing recursion? (or other things)
60 - Update unit tests for ConfigSchema
61 - Perhaps replace types with integer identifiers in ConfigSchema? (would be
62 smaller, but not by much).
65 - Factor demo.php into a set of Printer classes, and then create a stub
66 file for users here (inside the actual HTML Purifier library)
67 - Support exporting configuration, so users can easily tweak settings
68 in the demo, and then copy-paste into their own setup
74 3.2 release [Error'ed]
75 # Error logging for filtering/cleanup procedures
76 - XSS-attempt detection
78 3.3 release [Do What I Mean, Not What I Say]
79 # Additional support for poorly written HTML
80 - Microsoft Word HTML cleaning (i.e. MsoNormal, but research essential!)
81 - Friendly strict handling of <address> (block -> <br>)
82 - Remove redundant tags, ex. <u><u>Underlined</u></u>. Implementation notes:
83 1. Analyzing which tags to remove duplicants
84 2. Ensure attributes are merged into the parent tag
85 3. Extend the tag exclusion system to specify whether or not the
86 contents should be dropped or not (currently, there's code that could do
87 something like this if it didn't drop the inner text too.)
88 - Remove <span> tags that don't do anything (no attributes)
89 - Remove empty inline tags<i></i>
90 - Append something to duplicate IDs so they're still usable (impl. note: the
91 dupe detector would also need to detect the suffix as well)
92 - Externalize inline CSS to promote clean HTML
94 3.4 release [It's All About Trust] (floating)
95 # Implement untrusted, dangerous elements/attributes
96 # Implement IDREF support (harder than it seems, since you cannot have
97 IDREFs to non-existent IDs)
98 # Frameset XHTML 1.0 and HTML 4.01 doctypes
100 4.0 release [Beyond HTML]
101 # Legit token based CSS parsing (will require revamping almost every
102 AttrDef class). Probably will use CSSTidy class
103 # More control over allowed CSS properties (maybe modularize it in the
106 - Standardize token armor for all areas of processing
107 - Convert RTL/LTR override characters to <bdo> tags, or vice versa on demand.
108 Also, enable disabling of directionality
109 - Table of Contents generation (XHTML Compiler might be reusable)
111 5.0 release [To XML and Beyond]
112 - Extended HTML capabilities based on namespacing and tag transforms (COMPLEX)
113 - Hooks for adding custom processors to custom namespaced tags and
114 attributes, offer default implementation
115 - Lots of documentation and samples
118 - More refactoring to take advantage of PHP5's facilities
119 - Lots of profiling, make it faster!
120 - Plugins for major CMSes (COMPLEX)
122 - more! (look for ones that use WYSIWYGs)
123 - Complete basic smoketests
127 - Syntax highlighting with <pre> and possibly <?php
128 - Look at http://drupal.org/project/Modules/category/63 for ideas
130 Unknown release (on a scratch-an-itch basis)
131 # CHMOD install script for PEAR installs
132 ? Have 'lang' attribute be checked against official lists, achieved by
133 encoding all characters that have string entity equivalents
134 - Abstract ChildDef_BlockQuote to work with all elements that only
135 allow blocks in them, required or optional
136 - Reorganize Unit Tests
137 - Advanced URI filtering schemes (see docs/proposal-new-directives.txt)
138 - Implement lenient <ruby> child validation
139 - Explain how to use HTML Purifier in non-PHP languages / create
140 a simple command line stub (or complicated?)
141 - Fixes for Firefox's inability to handle COL alignment props (Bug 915)
142 - Automatically add non-breaking spaces to empty table cells when
143 empty-cells:show is applied to have compatibility with Internet Explorer
144 - Distinguish between default settings and explicitly set settings, so
145 configurations can be merged
146 - Nested configuration namespaces
147 - Allow scoped="scoped" attribute in <style> tags; may be troublesome
148 because regular CSS has no way of uniquely identifying nodes, so we'd
154 - Non-lossy smart alternate character encoding transformations (unless
156 - Pretty-printing HTML: users can use Tidy on the output on entire page
157 - Native content compression, whitespace stripping (don't rely on Tidy, make
158 sure we don't remove from <pre> or related tags): use gzip if this is
