     4 = KEY ====================
       
     5     # Flagship
       
     6     - Regular
       
     7     ? Maybe I'll Do It
       
     8 ==========================
       
     9 
       
    10 If no interest is expressed for a feature that may require 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!
       
    13 
       
    14 Things to do as soon as possible:
       
    15 
       
    16  - http://htmlpurifier.org/phorum/read.php?3,5560,6307#msg-6307
       
    17  - Think about allowing explicit order of operations hooks for transforms
       
    18  - Fix "<.<" bug (trailing < is removed if not EOD)
       
    19  - Build in better internal state dumps and debugging tools for remote
       
    20    debugging
       
    21  - Allowed/Allowed* have strange interactions when both set
       
    22  ? Transform lone embeds into object tags
       
    23  - Deprecated config options that emit warnings when you set them (with'
       
    24    a way of muting the warning if you really want to)
       
    25  - Make HTML.Trusted work with Output.FlashCompat
       
    26  - HTML.Trusted and HTML.SafeObject have funny interaction; general
       
    27    problem is what to do when a module "supersedes" another
       
    28    (see also tables and basic tables.)  This is a little dicier
       
    29    because HTML.SafeObject has some extra functionality that
       
    30    trusted might find useful.  See http://htmlpurifier.org/phorum/read.php?3,5762,6100
       
    31 
       
    32 FUTURE VERSIONS
       
    33 ---------------
       
    34 
       
    35 4.8 release [OMG CONFIG PONIES]
       
    36  ! Fix Printer. It's from the old days when we didn't have decent XML classes
       
    37  ! Factor demo.php into a set of Printer classes, and then create a stub
       
    38    file for users here (inside the actual HTML Purifier library)
       
    39  - Fix error handling with form construction
       
    40  - Do encoding validation in Printers, or at least, where user data comes in
       
    41  - Config: Add examples to everything (make built-in which also automatically
       
    42    gives output)
       
    43  - Add "register" field to config schemas to eliminate dependence on
       
    44    naming conventions (try to remember why we ultimately decided on tihs)
       
    45 
       
    46 5.0 release [HTML 5]
       
    47  # Swap out code to use html5lib tokenizer and tree-builder
       
    48  ! Allow turning off of FixNesting and required attribute insertion
       
    49 
       
    50 5.1 release [It's All About Trust] (floating)
       
    51  # Implement untrusted, dangerous elements/attributes
       
    52  # Implement IDREF support (harder than it seems, since you cannot have
       
    53    IDREFs to non-existent IDs)
       
    54      - Implement <area> (client and server side image maps are blocking
       
    55        on IDREF support)
       
    56  # Frameset XHTML 1.0 and HTML 4.01 doctypes
       
    57  - Figure out how to simultaneously set %CSS.Trusted and %HTML.Trusted (?)
       
    58 
       
    59 5.2 release [Error'ed]
       
    60  # Error logging for filtering/cleanup procedures
       
    61  # Additional support for poorly written HTML
       
    62     - Microsoft Word HTML cleaning (i.e. MsoNormal, but research essential!)
       
    63     - Friendly strict handling of <address> (block -> <br>)
       
    64  - XSS-attempt detection--certain errors are flagged XSS-like
       
    65  - Append something to duplicate IDs so they're still usable (impl. note: the
       
    66    dupe detector would also need to detect the suffix as well)
       
    67 
       
    68 6.0 release [Beyond HTML]
       
    69  # Legit token based CSS parsing (will require revamping almost every
       
    70    AttrDef class). Probably will use CSSTidy
       
    71  # More control over allowed CSS properties using a modularization
       
    72  # IRI support (this includes IDN)
       
    73  - Standardize token armor for all areas of processing
       
    74 
       
    75 7.0 release [To XML and Beyond]
       
    76  - Extended HTML capabilities based on namespacing and tag transforms (COMPLEX)
       
    77     - Hooks for adding custom processors to custom namespaced tags and
       
    78       attributes, offer default implementation
       
    79     - Lots of documentation and samples
       
    80 
       
    81 Ongoing
       
    82  - More refactoring to take advantage of PHP5's facilities
       
    83  - Refactor unit tests into lots of test methods
       
    84  - Plugins for major CMSes (COMPLEX)
       
    85     - phpBB
       
    86     - Also, a FAQ for extension writers with HTML Purifier
       
    87 
       
    88 AutoFormat
       
    89  - Smileys
       
    90  - Syntax highlighting (with GeSHi) with <pre> and possibly <?php
       
    91  - Look at http://drupal.org/project/Modules/category/63 for ideas
       
    92 
       
    93 Neat feature related
       
    94  ! Support exporting configuration, so users can easily tweak settings
       
    95    in the demo, and then copy-paste into their own setup
       
    96  - Advanced URI filtering schemes (see docs/proposal-new-directives.txt)
       
    97  - Allow scoped="scoped" attribute in <style> tags; may be troublesome
       
    98    because regular CSS has no way of uniquely identifying nodes, so we'd
       
    99    have to generate IDs
       
   100  - Explain how to use HTML Purifier in non-PHP languages / create
       
   101    a simple command line stub (or complicated?)
       
   102  - Fixes for Firefox's inability to handle COL alignment props (Bug 915)
       
   103  - Automatically add non-breaking spaces to empty table cells when
       
   104    empty-cells:show is applied to have compatibility with Internet Explorer
       
   105  - Table of Contents generation (XHTML Compiler might be reusable). May also
       
   106    be out-of-band information.
       
   107  - Full set of color keywords. Also, a way to add onto them without
       
   108    finalizing the configuration object.
       
   109  - Write a var_export and memcached DefinitionCache - Denis
       
   110  - Built-in support for target="_blank" on all external links
       
   111  - Convert RTL/LTR override characters to <bdo> tags, or vice versa on demand.
       
   112    Also, enable disabling of directionality
       
   113  ? Externalize inline CSS to promote clean HTML, proposed by Sander Tekelenburg
       
   114  ? Remove redundant tags, ex. <u><u>Underlined</u></u>. Implementation notes:
       
   115     1. Analyzing which tags to remove duplicants
       
   116     2. Ensure attributes are merged into the parent tag
       
   117     3. Extend the tag exclusion system to specify whether or not the
       
   118     contents should be dropped or not (currently, there's code that could do
       
   119     something like this if it didn't drop the inner text too.)
       
   120  ? Make AutoParagraph also support paragraph-izing double <br> tags, and not
       
   121    just double newlines.  This is kind of tough to do in the current framework,
       
   122    though, and might be reasonably approximated by search replacing double <br>s
       
   123    with newlines before running it through HTML Purifier.
       
   124 
       
   125 Maintenance related (slightly boring)
       
   126  # CHMOD install script for PEAR installs
       
   127  ! Factor out command line parser into its own class, and unit test it
       
   128  - Reduce size of internal data-structures (esp. HTMLDefinition)
       
   129  - Allow merging configurations.  Thus,
       
   130         a -> b -> default
       
   131         c -> d -> default
       
   132    becomes
       
   133         a -> b -> c -> d -> default
       
   134    Maybe allow more fine-grained tuning of this behavior. Alternatively,
       
   135    encourage people to use short plist depths before building them up.
       
   136  - Time PHPT tests
       
   137 
       
   138 ChildDef related (very boring)
       
   139  - Abstract ChildDef_BlockQuote to work with all elements that only
       
   140    allow blocks in them, required or optional
       
   141  - Implement lenient <ruby> child validation
       
   142 
       
   143 Wontfix
       
   144  - Non-lossy smart alternate character encoding transformations (unless
       
   145    patch provided)
       
   146  - Pretty-printing HTML: users can use Tidy on the output on entire page
       
   147  - Native content compression, whitespace stripping: use gzip if this is
       
   148    really important
