ParseTree

2.0.1

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]]]]] * Uses RubyInline, so it just drops in. * Includes SexpProcessor and CompositeSexpProcessor. * Allows you to write very clean filters. * Includes UnifiedRuby, allowing you to automatically rewrite ruby quirks. * ParseTree#parse_tree_for_string lets you parse arbitrary strings of ruby. * 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. * Does not work on the core classes, as they are not ruby (yet).
