Logo Bean-js

An esoteric byte-encoded code-golfing language derived from JavaScript

Install via npm:

npm install --save bean-js

Also works in-browser thanks to browserify and is ES5-compatible. Online interpreter available here.

Example usage:

<script src="js/bean.min.js"></script>
<script>
  var binary = bean.compile('[a+b,A+B,_,$]');
  var byteCount = binary.length;
  var source = bean.assemble(binary);
  var program = bean.program(binary);
  var input = '3\n4';
  var output = program(input);

  console.log(byteCount === 19);
  console.log(source === '[(a+b),(A+B),_,$,];');
  console.log(JSON.stringify(output) === '["34",7,["3","4"],[3,4]]');
</script>

Documentation

bean.compile(source)

Arguments

  • source An ASCII string containing valid JavaScript source: e.g. a function or variable declaration, expression, statement, or any combination thereof. An empty input string returns an empty output string.

Returns

  • binary An ISO8859-1 encoded binary string of equivalent Bean source.

Throws

  • Potentially any error throwable by babylon.parse(source)
  • RangeError if more than 32512 unique identifiers not listed in globals.json or identifiers.json are parsed from source.

bean.assemble(binary)

Arguments

  • binary An ISO8859-1 encoded binary string containing valid Bean source. An empty input string returns an empty output string.

Returns

  • source An ASCII string of equivalent JavaScript source.

Throws

  • RangeError if more than 32512 unique identifiers not listed in globals.json or identifiers.json are parsed from binary.

bean.program(binary)

Arguments

  • binary An ISO8859-1 encoded binary string containing valid Bean source. If an empty string is passed, the return value of the output function will be undefined, no matter what the input.

Returns

  • function program(stdin = "") {...} A function that optionally accepts standard line-separated input and implicitly initializes input before executing the Bean source. Returns the implicit output of the Bean source, which is the result of the last executed statement.
