Gir is an optimizing brainfuck interpreter in Javascript.

Name

𒌋𒀜 gir (Sumerian) - n. kiln

License

Everything in the repo is under Unlicense / CC0.

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

Examples

ircbot.js is an implementation of an IRC bot's brainfuck interpreter function. Smaller examples for every function are available in api.md

const gir = require('bf-gir');
let compiled = gir.compile(',[+.,]');
let input = gir.encodeUTF8('Foobar');
let vm = gir.newVM(compiled, input);
let result = gir.runVM(vm, 1000);

if(result.complete) {
	console.log(gir.decodeUTF8(result.state.output));
} else {
	console.log('Bf program terminated abnormally');
}

Installing

Gir is available at npm registry under the name bf-gir.
