** DESCRIPTION:
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
becomes:
[:defn,
:conditional1,
[:scope,
[:block,
[:args, :arg1],
[:if,
[:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],
[:return, [:lit, 1]],
nil],
[:return, [:lit, 0]]]]]
** FEATURES/PROBLEMS:
-
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).

Changes:
-
4 minor enhancements:
- parse_tree_show -f output is much cleaner now.
- ParseTree does a much more elegant job of handling different
versions. - ParseTree now has all node names in ParseTree::NODE_NAMES.
- ParseTree now raises exceptions instead of freakin’.
-
3 bug fixes:
- Used multiruby to test against 1.8.2-4, 1.8 cvs, and 1.9 cvs.
- Fixed incompatibilites introduced in ruby 1.8.4.
- Fixed some incompatibilites introduced in ruby 1.9.x.
