Lisp-JS

This library is an extendable interpreter / compiler for Lisp intended for use in any JS environment as a secure sandboxed execution runtime.

Example code:

const { run } = require('./index')

const code = `
  (process
    (def
      [sqrtIter x guess]
      (if
        [= (Math .abs (- x (* guess guess))) 0]
        guess
        (sqrtIter x (/ (+ guess (/ x guess)) 2))
      )
    )
    (def
      [sqrt x]
      (sqrtIter x 1)
    )
    (sqrt 9)
  )
`

let result = run({})(code)

console.log(result)

Roadmap

• Port pausable interpreter to TypeScript
• Implement a pausable interpreter
• Improve README and docs
• Support for comments (;) as a special form
• Implement code generation
• Implement a code generator for WebAssembly
• Allow concurrent execution
• Allow multi-threaded execution

Goals

• Build a language for Fractal over JS
• Be simple and performant

Docs

• Language is described in LANGUAGE.md

TODOs

• Tests lambdas to capture values
