CodeRay Version History

This files lists all changes in the CodeRay library since the 0.8.4 release.

Changes in 1.0

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.
  • 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.

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)

Tokens

  • REMOVED method stream?.
  • NEW methods encode_with, count, begin_group, end_group, begin_line, and end_line.

RENAMED: Tokens::AbbreviationForKind

Renamed from ClassOfKind; the term “token class” is no longer used in CodeRay. Instead, tokens have kinds.
See #122.

  • REMOVED token kinds :attribute_name_fat, :attribute_value_fat, :operator_fat, :tag_fat, :xml_text, :open, and :close.
  • ADDED token kinds :filename and :namespace.
  • CHANGED: Don’t raise error for unknown token kinds unless in $CODERAY_DEBUG mode.

Encoders::CommentFilter

  • NEW alias :remove_comments

Encoders::Filter

  • NEW option tokens.
  • CHANGED: Now it simply delegates to the output.
  • REMOVED include_text_token? and include_block_token? methods.

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.
  • ADDED support for :line_number_anchors.
    See #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.

Encoders::LinesOfCode

  • CHANGED: compile and finish methods are now protected.

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.

RENAMED: Encoders::TokenKindFilter

Renamed from TokenClassFilter.

  • NEW: Handles token groups.
    See #223.
  • RENAMED include_block_token? to include_group?.

Encoders::Statistic

  • CHANGED: Tokens actions are counted separately.

Encoders::YAML

  • NEW method call for allowing code like CodeRay::Duo[:python => :yaml].(code) in Ruby 1.9.

Scanners::Scanner

  • REMOVED helper method String#to_unix.
  • REMOVED method streamable?.

Scanners::CSS

  • NEW: Rudimentary support for the attr, counter, and counters functions.
    See #224.
  • NEW: Rudimentary support for CSS 3 colors.
  • CHANGED: Attribute selectors are highlighted as :attribute_name instead of :string.

Scanners::Debug

  • NEW: Support for line tokens (begin_line and end_line represented by [ and ].)
  • FIXED: Don’t send :error and nil tokens for buggy input any more.
  • FIXED: Closes unclosed tokens at the end of scan_tokens.
  • IMPROVED: Highlight unknown tokens as :error.
  • CHANGED: Raises an error when trying to end an invalid token group.

Scanners::Delphi

  • FIXED: Closes open string groups.

Scanners::Diff

  • NEW: Highlighting of code based on file names.
    See ticket #52.
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 buggy for multi-line tokens.
  • NEW: Highlight the file name in the change headers as :filename.
  • CHANGED: Highlight unknown lines as :comment instead of :head.

Scanners::HTML

  • FIXED: Closes open string groups.

Scanners::JavaScript

  • IMPROVED: Added NaN and Infinity to list of predefined constants.

Scanners::Java

  • NEW: Package names are highlighted as :namespace.
    See #210.

Scanners::Plaintext

  • IMPROVED: Just returns the string without scanning (faster).
This is much faster than scanning until /\z/ in Ruby 1.8.

Scanners::Python

  • CHANGED: Docstrings are highlighted as :comment.
    See #190.

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.

Scanners::Ruby

  • ADDED more predefined keywords (see http://murfy.de/ruby-constants).
  • IMPROVED support for singleton method definitions.
    See #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.

Scanners::Scheme

  • CHANGED: Does use :operator instead of :operator_fat now.

Scanners::SQL

  • IMPROVED: Extended list of keywords and functions (thanks to Joshua Galvez).
See #221.
  • FIXED: Closes open string groups.

NEW: Styles::Alpha

A style that uses transparent HSLA colors as defined in CSS 3.
See #199.

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!

  • FIXED strings are closed correctly
    (#138)
