ParseTree version 3.0.9 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
becomes:
[:defn,
:conditional1,
[:scope,
[:block,
[:args, :arg1],
[:if,
[:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],
[:return, [:lit, 1]],
nil],
[:return, [:lit, 0]]]]]

6 minor enhancements:
- Added a bunch of new tests from PTTC.

- Handle rewriting block_pass in iter.
- Imported RawParseTree test data from PTTC.
- Removed rewrite_masgn requirement for 4 slots.
-
3 bug fixes:
- Fixed dependencies to ensure they’re not going to use ruby_parser 3
and friends. - Fixed segv for NODE_BLOCK_PASS in iter (nd_iter == 1… go boom)
- Remove nil body in iter (I think this is wrong, but whatevs).
- Fixed dependencies to ensure they’re not going to use ruby_parser 3
