ruby2c version 1.0.0.6 has been released! - [http://rubyforge.org/projects/ruby2c/](http://rubyforge.org/projects/ruby2c/) - [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) - \ ruby\_to\_c translates a static ruby subset to C. Hopefully it works. NOTE ! NOTE ! NOTE ! NOTE ! NOTE ! NOTE ! NOTE ! NOTE ! NOTE ``` THIS IS BETA SOFTWARE! ``` NOTE ! NOTE ! NOTE ! NOTE ! NOTE ! NOTE ! NOTE ! NOTE ! NOTE RubyToC has the following modules: - Rewriter - massages the sexp into a more consistent form. - TypeChecker - type inferencer for the above sexps. - RubyToRubyC - converts a ruby (subset) sexp to ruby interals C. - RubyToAnsiC - converts a ruby (subset) sexp to ANSI C. and the following tools: - translate.rb - Translates a given file to C. Changes: ### 1.0.0.6 / 2009-06-23 1 major enhancement: - Switched from ParseTree to ruby\_parser for 1.9 compatibility. woo. - All translate/process methods are gone since we can’t reflect at runtime. 43 minor enhancements: - Added IterRewriter for finding free variables in iter nodes. - Added dxstr. - Added lots of new and missing tests - Added not, array, lit\_long\_negative, lit\_range[23], lit\_regexp{\_n,\_once}, lit\_sym{,\_splat} - Added pct\_w tests - Added process\_defx to ruby\_to\_ansi\_c.rb - Added test data for array\_pct\_W, array\_pct\_W\_dstr, attrasgn\_index\_equals, attrasgn\_index\_equals\_space, and attrset. - Added tests for “and”. PONG to eric - Added to\_ary and masgn for TypeChecker. - Added xstr support. - Added yield(\*ary) - Cleaned up rewriter.rb and made changes for pt\_testcase.rb - Cleaned up some free\_vars processing code. - Converted everything to new enhanced PTTC test scheme. - Enhanced with\_scope to allow for static arrays. - Extended Environment to separately store both types and values. - Extern methods to support rb\_iterate, including #each and #each\_with\_index. - Free var static declarations for C layers. - Merged IterRewriter into CRewriter and make typed. - Migrated as much out of rewriter as possible. - Modernized via hoe. - Moved to full PTTC + UnifiedRuby. - Pulled dstr up from ZenObfuscator. - Pulled up tests, process\_args, with\_scope, and process\_scope from obfuscator - Pushed unique.rb up to PT - Removed Environment methods that pushed up to ruby\_parser. - Removed Sexp#sexp\_type - Removed accessor, accessor\_equals since they don’t exist in PTTC. - Removed bin/\* - Removed dead test - Removed redundant defn\_lvar\_boundary, but added call to lvar\_def\_boundary. - Renamed blocks to extra\_methods in ruby\_to\_ruby\_c. - Renamed environment.rb to r2cenvironment.rb (incl tests) - Renamed iter\_functions to extra\_methods in crewriter. - Reordered so RubyToRubyC was always after RubyToAnsiC. - Some optimizations cleaning up Type#method\_missing. Drops test time ~30%. - Split rewriter.rb to crewriter.rb (and renamed class to CRewriter). - Split up and deleted support.rb (and tests). - Switched from makefile to rakefile. - Switched to minitest - Test or node. - Track and trigger changes on pt\_testcase.rb and r2ctestcase.rb - Used Hoe#add\_include\_dirs to clean up rakefile. - 12 bug fixes:
