ParseTree 1.5.0 Released
Published 2006-09-24 @ 13:22
ParseTree version 1.5.0 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, symbols, and integers.
As an example:
def conditional1(arg1) if arg1 == 0 then return 1 end return 0 end
[: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 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.
- Only works on methods in classes/modules, not arbitrary code.
Does not work on the core classes, as they are not ruby (yet).
- 5 minor enhancements:
- Added parse_tree_audit.
- Added reporting of unsupported nodes that have processors.
- YAY! class method support! generated as :”self.blah”
- Add parse_tree_for_string.
- Converted Rakefile+gemspec to Hoe-based Rakefile.
- 6 bug fixes:
- Did some preliminary work on 1.9 compatibility.
- Fixed tests for some changes/clarifications.
- Fixed resbody: should have nil exceptions list when no exception rescued.
- Fixed op_asgn1 and op_asgn2.
- Fixed incompatibility with new inline changes.
- Fixed VALUE decl in parse_tree.rb
