ParseTree version 2.2.0 has been released!
ParseTree is a C extension (using RubyInline) that extracts the parse
tree for an entire class or a specific method and returns it as a
s-expression (aka sexp) using ruby's arrays, strings
... [More]
, symbols, and
integers.
As an example:
def conditional1(arg1)
if arg1 == 0 then
return 1
end
return 0
end
becomes:
[:defn,
:conditional1,
[:scope,
[:block,
[:args, :arg1],
[:if,
[:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],
[:return, [:lit, 1]],
nil],
[:return, [:lit, 0]]]]]
Changes:
### 2.2.0 / 2008-06-09
* 18 minor enhancements:
* Added 1.9 and rubinius to multiruby skip list.
* Added 1.9 fixes for SexpProcessor.
* Added compatibility changes for regexp option values.
* Added custom compact since Array#compact is hostile to subclasses.
* Added some tests for wonky index edge cases. some commented out.
* Added test changes for 1.9 and r2r changes. Esp fixed regexp differences.
* Added tests for dasgn, proc arities,
* Added/updated some tests for ruby_parser.
* Changed tests to default to nil for verbose.
* Fixed all assertions deprecated in miniunit.
* Raises LoadError if incompatible ruby, allows fallback to ruby_parser.
* Removed Unified's rewrite_fbody and moved up into defn... not sure about that.
* Removed argscat rewriter from unified_ruby.rb
* Renamed shadowed variable name.
* Reworked parse_tree_for_(method|string) to take optional verbose arg.
* Started removing ending newlines from pt_testcase.rb.
* Uncommented all commented out tests. ruby_parser must not be a pansy.
* Updated rakefile for new hoe abilities.
* 3 bug fixes:
* Fixed 1.8.[45] wrt dasgn_curr declaration removal.
* Fixed pt_testcase bug.
* Fixes for colon2/3 in class/module/cdecls. [Less]

Thanks to Luis Lavena ParseTree now has gems precompiled for windows! This makes things like ruby2ruby, heckle, and much more that much more accessible to the OS-challenged!

ParseTree version 2.1.1 has been released!
ParseTree is a C extension (using RubyInline) that extracts the parse
tree for an entire class or a specific method and returns it as a
s-expression (aka sexp) using ruby's arrays, strings
... [More]
, symbols, and
integers.
As an example:
def conditional1(arg1)
if arg1 == 0 then
return 1
end
return 0
end
becomes:
[:defn,
:conditional1,
[:scope,
[:block,
[:args, :arg1],
[:if,
[:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],
[:return, [:lit, 1]],
nil],
[:return, [:lit, 0]]]]]
* Uses RubyInline, so it just drops in.
* Includes SexpProcessor and CompositeSexpProcessor.
* Allows you to write very clean filters.
* Includes UnifiedRuby, allowing you to automatically rewrite ruby quirks.
* ParseTree#parse_tree_for_string lets you parse arbitrary strings of ruby.
* Includes parse_tree_show, which lets you quickly snoop code.
* echo "1 1" | parse_tree_show -f for quick snippet output.
* Includes parse_tree_abc, which lets you get abc metrics on code.
* abc metrics = numbers of assignments, branches, and calls.
* whitespace independent metric for method complexity.
* Includes parse_tree_deps, which shows you basic class level dependencies.
* Does not work on the core classes, as they are not ruby (yet).
Changes:
### 2.1.1 / 2007-12-22
* 1 bug fix:
* _sigh_ apparently I've been running w/o all my anal compiler flags on. [Less]

ruby_parser version 1.0.0 has been released!
ruby_parser (RP) is a ruby parser written in pure ruby (utilizing
racc--which does by default use a C extension). RP's output is
the same as ParseTree's output: s-expressions using ruby's
... [More]
arrays and
base types.
## FEATURES/PROBLEMS:
* Pure ruby, no compiles.
* Incredibly simple interface.
* Output is 100% equivalent to ParseTree.
* Can utilize PT's SexpProcessor and UnifiedRuby for language processing.
* Known Issue: Speed sucks currently. 5500 tests currently run in 21 min.
* Known Issue: Code is waaay ugly. Port of a port. Not my fault. Will fix RSN.
* Known Issue: I don't currently support newline nodes.
* Known Issue: Totally awesome.
* Known Issue: dasgn_curr decls can be out of order from ParseTree's.
* TODO: Add comment nodes.
## SYNOPSIS:
RubyParser.new.parse "1 1"
# => s(:call, s(:lit, 1), : , s(:array, s(:lit, 1)))
Changes:
## 1.0.0 / 2007-12-20
* 1 major enhancement
* Birthday! [Less]

* whitespace independent metric for method complexity.
* Includes parse_tree_deps, which shows you basic class level dependencies.
* Does not work on the core classes, as they are not ruby (yet).
Changes:
* 13 minor enhancements:
* Added (partial) regexp flag support, currently numerical. ugh.
* Added -a flag to parse_tree_show to turn on newline (all) nodes.
* Added -r to parse_tree_show for raw arrays instead of sexps.
* Added Unifier (SexpProcessor) class to unified_ruby.rb.
* Added a ton of tests while working on ruby_parser.
* Added ability to tell proc {} (nil arg slot) from proc {||} (0 arg slot)
* Added context tracking to rewriting phase... slightly broken.
* Added evstr support. (I hate evan)
* Added usage for parse_tree_show.
* Changed verbose to be true all the time in parse_tree_for_string.
* Removed process_level from SexpProcessor... just look at context size instead.
* Revamped ParseTree. No more passing around newline. Pass around self instead.
* I'm starting to dislike ruby's AST. It is REALLY inconsistent.
* 6 bug fix:
* SexpProcessor#assert_type now a bit safer with bad values.
* Uncovered a bug in ruby (AST changes when -v used), added handler code.
* Fixed NODE_BLOCK and massively simplified in the process.
* Fixed rewrite_defs to deal with non-block asts.
* Fixed test/unit hack so it does not die under miniunit.
* Found a bug in PT where parse_tree_for_string had some shadowed variables. [Less]
