| === 1.8.5 / 10-21-10 |
| |
| * 1 Bug Fix |
| - fixed ANTLR3::InteractiveStringStream to work with Ruby 1.9. The lexer main script |
| should function in interactive mode for Ruby 1.9 now. |
| |
| === 1.8.4 / 10-08-10 |
| |
| * 1 Bug Fix |
| - removed directory dependency from tasks created by ANTLR3::Task, which caused |
| compilation to be performed twice in some situations |
| |
| === 1.8.3 / 10-08-10 |
| |
| * 2 Bug Fixes |
| - fixed typo in TokenRewriteStream#cast_range |
| - added work-around code to handle the lack of support for StopIteration in Rubinius |
| |
| === 1.8.2 / 10-02-10 |
| |
| * Bug Fix: removed references to Parser#token_stream |
| - changed references to Parser#token_stream to Parser#input in `antlr3/profile.rb' to |
| avoid "private method token_stream called" errors in profile mode |
| |
| * Minor Enhancement: new samples included with the distribution |
| - added a newly developed `samples/JavaScript.g' file for parsing JavaScript. |
| While not entirely complete and flawless, it does a pretty good job |
| of parsing JavaScript up through Firefox's 1.6 version of the language. |
| - included the `samples/standard' directory with the package distribution, |
| which has been in the development repository for a while, but I never |
| updated the package spec to include these files. |
| |
| === 1.8.0 / 07-03-10 |
| |
| * Bug Fix / Major Enhancement: made antlr3 compatible with ruby 1.9 |
| - altered ANTLR3::StringStream to always have #peek return an integer in both |
| Ruby 1.8 and 1.9. In 1.9, @data is now an array of code point values and |
| the new instance variable @string contains the actual string. In Ruby 1.8, |
| both @data and @string contain the string value. |
| - lexer code is no longer generated using '?c' character syntax; characters |
| are now represented as hexadecimal integers to make the code compatible |
| with Ruby 1.9 |
| |
| === 1.7.5 / 06-18-10 |
| |
| * Minor Enhancements |
| - added #compile! and #clobber! methods to directly invoke the 'compile' |
| and 'clobber' tasks respectively |
| |
| * Bug Fixes |
| - removed special ruby-stylistic formatting on syntactic predicate method names to |
| fix a bad bug in code-generation that cropped up in more complex grammars |
| |
| === 1.7.2 / 05-16-10 |
| |
| * Minor Enhancements |
| - added new #hold convenience method to ANTLR3::CommonTokenStream |
| |
| * Bug Fixes |
| - corrected a typo in ANTLR3::Error#FailedPredicate which caused a |
| NoMethodError to raise instead of FailedPredicate when semantic |
| predicates failed |
| |
| * Documentation |
| - added more content to the ruby antlr3 guide |
| - set up an official project website at |
| http://antlr.ohboyohboyohboy.org |
| |
| === 1.7.0 / 04-20-10 |
| |
| * Minor Enhancements |
| - added new #each_on_channel and #walk convenience methods to ANTLR3::CommonTokenStream |
| |
| * Bug Fixes |
| - discovered and fixed a rare but serious bug in the way the output code evaluates |
| syntactic predicates |
| |
| * Documentation |
| - began developing a more thorough usage guide for the package |
| - the guide is currently available on GitHub at |
| http://ohboyohboyohboy.github.com/antlr3 |
| |
| === 1.6.3 / 02-12-10 |
| |
| * 4 Minor Enhancements |
| - added --help and --version options to antlr4ruby |
| - documented the antlr4ruby source and added license information |
| - prettied up the source code in all of the library files a little |
| - added a hoe-based rakefile with the gem distribution of the source code |
| |
| === 1.6.0 / 01-27-10 |
| |
| * 4 Minor Enhancements to runtime library |
| - CommonTokenStream and subclasses can now also accept another CommonTokenStream |
| object, serving sort of as a copy constructor. This provides a reasonable way |
| to cast a CommonTokenStream into a TokenRewriteStream and vice-versa |
| - CommonTreeNodeStream can take an options hash at the end of any of its various |
| signatures to provide values for attributes like token_stream |
| - If a parser is created with a CharacterStream object (i.e., StringStream), it |
| will also try to cast it by checking for an associated lexer (like it currently |
| does when created with String or IO objects). |
| - Template-output mode parsers have a new class method "load_templates( path )" |
| which will attempt to load the template group file at +path+ and, if successful, |
| set it to the parser's default template library. (See the CMinus example set for |
| an example of how this can be used) |
| |
| * 2 bug fixes / 1 change to templates |
| - backtracking was broken in situations where recognition failed when |
| a semantic predicate was encountered as the template code did not |
| throw BacktrackingFailed when it was in backtracking mode instead of |
| PredicateFailed |
| - rule memoization also had a major bug in that rules that were memoized |
| after failure did not throw BacktrackingFailed when it was needed |
| - I changed `attribute scope' structures (not rule return scopes, but |
| the groups of attributes you can assign to rules with the `scope' keyword), |
| from being implemented as named constants in the class body to class |
| variables belonging to the recognizer. As class variables do not need |
| to follow naming conventions, this provides more freedom in naming without |
| all of the ugly name mangling. These are generally used privately by parsers, |
| so it shouldn't be too drastic of a change as to break end user's code. |
| |
| === 1.5.0 / 01-25-10 |
| |
| * 2 minor enhancements |
| - Added BaseTree#walk, which iterates in a top-down fashion across all notes in a tree. |
| - Added BaseTree#prune, which stops decent into the current node during BaseTree#walk. |
| |
| * 1 optimization |
| - changed `closure loops' ( uses of the `*' or `+' modifiers ) from using |
| Kernel#loop to `while true ... end' style loops, which should be slightly |
| faster |
| |
| * new test code |
| - test/functiona/template-output/template-output.rb serves as a basic |
| functional test implementation for the new template output mode |
| |
| === 1.4.0 / 01-17-10 |
| |
| * 1 major new feature |
| - finished basic implementation of a template output mode. |
| - lib/antlr3/template.rb defines a number of classes for |
| ERB-based template output translation |
| - templates/ST.stg defines the Ruby target templates to |
| generate template output mode recognizers |
| |
| * new test code |
| - added template unit tests at test/unit/test-template.rb |
| - test/functional/template-output/template-output.rb serves as a basic |
| functional test implementation for the new template output mode |
