ParseTree version 1.2.0 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, symbols, and
As an example:
if arg1 == 0 then
[:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],
[:return, [:lit, 1]],
[:return, [:lit, 0]]]]]
+ Uses RubyInline, so it just drops in.
+ Includes SexpProcessor and CompositeSexpProcessor.
+ Allows you to write very clean filters.
+ Includes show.rb, which lets you quickly snoop code.
+ Includes abc.rb, which lets you get abc metrics on code.
+ abc metrics = numbers of assignments, branches, and calls.
+ whitespace independent metric for method complexity.
+ Only works on methods in classes/modules, not arbitrary code.
+ Does not work on the core classes, as they are not ruby (yet).
+ 9 minor enhancements
+ ParseTree now returns symbols for all data except in :str and :lit.
+ This WILL break existing code! (as if any exists)
+ ParseTree.parse_tree now takes a list of classes, no optional method.
+ ParseTree.parse_tree_for_method(klass, method) added.
+ ParseTree.parse_tree now returns a list of :class/:module nodes.
+ Added -f to parse_tree_show for uber fast demos.
+ Added -q to parse_tree_show to NOT use pp so it is mucho faster.
+ running with $DEBUG will trace the methods and nodes as processed.
+ Added rdoc to everything.
+ 4 bug fixes
+ Bus error in iter/for nodes where arg list is empty now fixed.
+ Bus error when handling 'def method(*)' is now fixed.
+ Unnamed classes and superclasses (ugh) are now handled.
+ parse_tree_abc now enumerates actual types rather than every token.
