An alternate implementation of the terse GolfScript language. All features should be supported except for Ruby string interpolation. The language has many corner cases, so please notify me if you find a difference in behavior from the original Ruby implementation!

golfscript prog.gs < stdin.txt # program and stdin
golfscript < prog.gs # just program, empty stdin
cabal test runs a variety of included programs (taken from the
Anarchy Golf server) to verify output against the
official Ruby interpreter (make sure ruby is in your path). See the test
folder for the required format. A test succeeds if both versions succeed with
the exact same stdout, or if both versions exit with a non-success code (on the
Ruby side, this indicates a Ruby exception).

Comments are not preserved in the string representation of a block. Currently blocks are parsed into code, and then unparsed back into a string. This is silly but to avoid doing so would be complicated.
-
Sorting an array with multiple types is well-defined -- it uses the default Haskell datatype ordering where
Int < Arr < Str < Blk. The original interpreter crashes.
