h1=. CodeRay Version History
 
p=. _This files lists all changes in the CodeRay library since the 0.8.4 release._
 
h2. Changes in 1.0
 
h3. Direct Streaming
 
CodeRay 1.0 introduces _Direct Streaming_ as a faster and simpler alternative to Tokens. It means that all Scanners, Encoders and Filters had to be rewritten, and that older scanners using the Tokens API are no longer compatible with this version.
 
The benefit of this change is more speed (benchmarks show 10% to 50% more tokens per second compared to CodeRay 0.9), a simpler API, and less code.
 
Changes related to the new tokens handling include:
* *CHANGED*: The Scanners now call Encoders directly; tokens are not added to a Tokens array, but are send to the Encoder as a method call. The Tokens representation (which can be seen as a cache now) is still present, but as a special case; Tokens just encodes the given tokens into an Array for later use.
* *CHANGED*: The token actions (@text_token@, @begin_group@ etc.) are now public methods of @Encoder@ and @Tokens@.
* *REWRITE* of all Scanners, Encoders, Filters, and Tokens.
* *RENAMED* @:open@ and @:close@ actions to @:begin_group@ and @:end_group@.
* *RENAMED* @open_token@ and @close_token@ methods to @begin_group@ and @end_group@.
* *NEW* method @#tokens@ allows to add several tokens to the stream. @Tokens@ and @Encoders::Encoder@ define this method.
* *CHANGED* The above name changes also affect the JSON, XML, and YAML encoders. CodeRay 1.0 output will be incompatible with earlier versions.
* *REMOVED* @TokenStream@ and the @Streamable@ API and all related features like @NotStreamableError@ are now obsolete and have been removed.

h3. General changes
 
* *IMPROVED* documentation in general; additions, corrections and cleanups
* *FIXED* some image links in the documentation
* *IMPROVED* Ruby 1.9 support (_._ not in @$LOAD_PATH@)

h3. @Tokens@
 
* *REMOVED* methods @#stream?@, @#each_text_token@.
* *REMOVED* @#text@ and @#text_size@ methods. Use the @Text@ encoder instead.
* *REMOVED* special implementation of @#each@ taking a filter parameter. Use @TokenKindFilter@ instead.
* *NEW* methods @encode_with@, @count@, @begin_group@, @end_group@, @begin_line@, and @end_line@.

h3. *RENAMED*: @Tokens::AbbreviationForKind@
 
Renamed from @ClassOfKind@; the term "token class" is no longer used in CodeRay. Instead, tokens have _kinds_.
See "#122":http://redmine.rubychan.de/issues/122.
 
* *REMOVED* token kinds @:attribute_name_fat@, @:attribute_value_fat@, @:operator_fat@, @:tag_fat@, @:xml_text@, @:open@, and @:close@.
* *ADDED* token kinds @:filename@, @:namespace@, and @:eyecatcher@.
* *CHANGED*: Don't raise error for unknown token kinds unless in @$CODERAY_DEBUG@ mode.

h3. @Encoders::CommentFilter@
 
* *NEW* alias @:remove_comments@

h3. @Encoders::Filter@
 
* *NEW* option @tokens@.

h3. @Encoders::HTML@
 
The HTML encoder was cleaned up and simplified.
 
* *CHANGED* the default style to @:alpha@.
* *NEW*: HTML 5 and CSS 3 compatible, IE incompatible.
  See "#215":http://redmine.rubychan.de/issues/215.
* *ADDED* support for @:line_number_anchors@.
  See "#208":http://redmine.rubychan.de/issues/208.
* *CHANGED*: Use double click to toggle line numbers in table mode (as single 
  click jumps to an anchor.)
* *REMOVED* support for @:line_numbers => :list@.
* *FIXED* splitting of lines for @:line_numbers => :inline@, so that the line
  numbers don't get colored, too.
* *RENAMED* @Output#numerize@ to @#number@, which is an actual English word.

h3. @Encoders::LinesOfCode@
 
* *CHANGED*: @compile@ and @finish@ methods are now protected.

h3. @Encoders::Terminal@
 
* *RENAMED* from @Encoders::Term@, added @:term@ alias.
* *CLEANUP*: Use @#setup@'s @super@, don't use @:procedure@ token class.
* *CHANGED*: @#token@'s second parameter is no longer optional.
* *REMOVED* colors for obsolete token kinds.
* *FIXED* handling of line tokens.

h3. @Encoders::Text@
 
* *FIXED* default behavior of stripping the trailing newline.

h3. *RENAMED*: @Encoders::TokenKindFilter@
 
Renamed from @TokenClassFilter@.

* *NEW*: Handles token groups.
  See "#223":http://redmine.rubychan.de/issues/223.
* *RENAMED* @include_block_token?@ to @include_group?@.

h3. @Encoders::Statistic@
 
* *CHANGED*: Tokens actions are counted separately.

h3. @Encoders::YAML@
 
* *NEW* method @call@ for allowing code like @CodeRay::Duo[:python => :yaml].(code)@ in Ruby 1.9.

h3. @Scanners::Scanner@
 
* *REMOVED* helper method @String#to_unix@.
* *REMOVED* method @streamable?@.
* *NEW*: The @#tokenize@ method also takes an Array of Strings as source. The
  code is highlighted as one and split into parts of the input lengths
  after that using @Tokens#split_into_parts@.

h3. @Scanners::CSS@
 
* *NEW*: Rudimentary support for the @attr@, @counter@, and @counters@ functions.
  See "#224":http://redmine.rubychan.de/issues/224.
* *NEW*: Rudimentary support for CSS 3 colors.
* *CHANGED*: Attribute selectors are highlighted as @:attribute_name@ instead of @:string@.

h3. @Scanners::Debug@

h3. @Scanners::Delphi@
 
* *FIXED*: Closes open string groups.

h3. @Scanners::Diff@
 
* *NEW*: Highlighting of code based on file names.
  See ticket "#52":http://redmine.rubychan.de/issues/52.
  
  Use the @:highlight_code@ option to turn this feature off. It's enabled
  by default.
  
  This is a very original feature. It enables multi-language highlighting for
  diff files, which is especially helpful for CodeRay development itself. The
  updated version of the scanner test suite generated .debug.diff.html files
  using this.
  
  Note: This is still experimental. Tokens spanning more than one line
  may get highlighted incorrectly. CodeRay tries to keep scanner states
  between the lines and changes, but the quality of the results depend on
  the scanner.
* *NEW*: Inline change highlighting, as suggested by Eric Thomas.
  See ticket "#227":http://redmine.rubychan.de/issues/227 for details.
  
  Use the @:inline_diff@ option to turn this feature off. It's enabled by
  default.
  
  For single-line changes (that is, a single deleted line followed by a single
  inserted line), this feature surrounds the changed parts with an
  @:eyecatcher@ group which appears in a more saturated background color.
  The implementation is quite complex, and highly experimental. The problem
  with multi-layer tokenizing is that the tokens have to be split into parts.
  If the inline change starts, say, in the middle of a string, then additional
  @:end_group@ and @:begin_group@ tokens must be inserted to keep the group
  nesting intact. The extended @Scanner#tokenize@ method and the new
  @Tokens#split_into_parts@ method take care of this.
* *NEW*: Highlight the file name in the change headers as @:filename@.
* *CHANGED*: Highlight unknown lines as @:comment@ instead of @:head@.

h3. @Scanners::HTML@
 
* *FIXED*: Closes open string groups.

h3. @Scanners::JavaScript@
 
* *IMPROVED*: Added @NaN@ and @Infinity@ to list of predefined constants.

h3. @Scanners::Java@
 
* *NEW*: Package names are highlighted as @:namespace@.
  See "#210":http://redmine.rubychan.de/issues/210.

h3. @Scanners::Plaintext@
 
* *IMPROVED*: Just returns the string without scanning (faster).
 
 This is much faster than scanning until @/\z/@ in Ruby 1.8.

h3. @Scanners::Python@
 
* *CHANGED*: Docstrings are highlighted as @:comment@.
  See "#190":http://redmine.rubychan.de/issues/190.

h3. *NEW*: @Scanners::Raydebug@
 
Copied from @Scanners::Debug@, highlights the token dump instead of importing it. It also reacts to the @.raydebug@ file name suffix now.

h3. @Scanners::Ruby@
 
* *ADDED* more predefined keywords (see http://murfy.de/ruby-constants).
* *IMPROVED* support for singleton method definitions.
  See "#147":http://redmine.rubychan.de/issues/147.
* *FIXED*: Don't highlight methods with a capital letter as constants
  (eg. GL.PushMatrix).
* *NEW*: Highlight buggy floats (like .5) as @:error@.
* *CLEANUP* of documentation, names of constants and variables, state handling.
* *NEW*: Complicated rule for recognition of @foo=@ style method names.
* *NEW*: Handles @:keep_state@ option (a bit; experimental).
  
  Actually, Ruby checks if there is @[~>=]@, but not @=>@ following the name.

h3. @Scanners::Scheme@
 
* *CHANGED*: Does use @:operator@ instead of @:operator_fat@ now.

h3. @Scanners::SQL@
 
* *IMPROVED*: Extended list of keywords and functions (thanks to Joshua Galvez).
 
  See "#221":http://redmine.rubychan.de/issues/221.
* *FIXED*: Closes open string groups.

h3. @Scanners::YAML@
 
* *FIXED*: Allow spaces before colon in mappings.
 
  See "#231":http://redmine.rubychan.de/issues/231.

h3. *NEW*: @Styles::Alpha@
 
A style that uses transparent HSLA colors as defined in CSS 3.
See "#199":http://redmine.rubychan.de/issues/199.

h3. @FileType@
 
* *REMOVED* @FileType#shebang@ is a protected method now.
* *NEW*: Recognizes @.gemspec@, @.rjs@, @.rpdf@ extensions and @Capfile@ as Ruby.
  
  Thanks to the authors of the TextMate Ruby bundle!

h3. @Plugin@
 
* *IMPROVED*: @register_for@ sets the @plugin_id@; it can now be a @Symbol@.
