Status

Gir can parse, prettyprint, and run programs in brainfuck. Gir supports following optimizations:

• Turn runs of +- or <> into one command
• Turn [-] or [+] into one command
• Add offsets to commands that modify tape, to reduce moving tape head
• Turn multiply loops into one command

TODO

gir.js

• Implement :;#
• Make VM and transformMultiplyLoops use a Proxied object that gives out 0 for nonexistent elements for tape and allows using [] interface
• Keep a cache of compiled programs in run()
• Support for other types of EOF?
