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, symbols, and
As an example:
if arg1 == 0 then
[:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],
[:return, [:lit, 1]],
[:return, [:lit, 0]]]]]

- Includes SexpProcessor and CompositeSexpProcessor.
- Allows you to write very clean filters.
- Includes UnifiedRuby, allowing you to automatically rewrite ruby
- ParseTree#parse_tree_for_string lets you parse arbitrary strings of
- 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
- Does not work on the core classes, as they are not ruby (yet).
