ruby2ruby provides a means of generating pure ruby code easily from ParseTree's Sexps. This makes making dynamic language processors much easier in ruby than ever before.

Changes:

1.2.3 / 2009-06-23

• 4 minor enhancements:

  • Overhauled 4-generation tests to use RubyParser. Much cleaner
  • Removed last of ParseTree. Fully switched to RubyParser.
  • Switched to minitest
  • Updated Rakefile to new hoe capabilities

There seems to be some confusion and/or panic about ParseTree that I'd like to clear up:

Because of changes to internals in 1.9, ParseTree simply can not work. I asked for hooks/options to allow us to get to the information but they never arrived.

Specifically if you're using ParseTree to access the AST of a live method/block/proc, you're SOL. If you're just using ParseTree to do static analysis, then you can switch to ruby_parser in about a minute of work and you're good to go.

Here is the plan for my projects:

• RubyToC-1.0.0.5 = switching to ruby_parser
• flog-2.1.0 = switching to ruby_parser
• heckle-1.4.2 = dead, unless we can think of something soon.
• ruby2ruby-1.2.2 = dropping block/proc support.
• ruby_parser-2.0.2 = no clue why it has a dependency still, no worries here.
• ZenHacks-1.0.1 = dropping block/proc support -- not that I support this.

I don't know the status of most of the projects dependent on PT or how they're going to deal with this issue. If you use one of these projects directly or indirectly and that project relies on PT for live method/block/proc, then you're probably going to be stuck on 1.8 for a while:

• SuperCaller-1.0.0 = unsupported - can drop live method support
• ambition-0.5.4
• argible-0.1.1
• integrity-0.1.9.3
• merb-action-args-1.0.11
• nitpick-1.0.2
• protocol-0.8.1
• red-4.1.7
• reek-1.0.0 = probably doesn't need live analysis
• roodi-1.3.5
• ruby_diff-0.2
• rubyjs-0.8.0
• sake-1.0.15
• thorero-action-args-0.9.4

There are probably other projects out there dependent on PT that I don't know about. All I've listed here are rubyforge gems that depend on PT in their gemspec.

You can check your gems using this:

gem list | egrep "(ambition|argible|integrity|merb-action-args|nitpick|protocol|red|reek|roodi|ruby_diff|rubyjs|sake|thorero-action-args)"

• 3 minor enhancements:

  • Added -s to display sexp before printing r2r
  • Added a bunch of backslash and masgn tests.
  • Refactored tests.

• 4 bug fixes:

  • Fixed iters to deal with empty bodies.
  • Fixed process_call for a number of cases incl [], []=, and args processing.
  • Fixed process_hash to always generate braces if in arglist.
  • Switched process_alias to producing alias again, needed for globals.

% gauntlet report parsetree

KirbyBase-2.6

the fact that I can incrementally fix something and then run it against the known failures makes doing compatibility work via gauntlet pure joy. I've been using gauntlet to compare parsetree to rubyparser and to do round trips between rubyparser and ruby2ruby. It's finding _a lot of stuff for me to work on.
