Solo Lang

Minimal lisp syntax to plain and readable JavaScript compiler

Solo is not a separate language but really a way of writing JavaScript in a lispy syntax. See for yourself...

Getting started

$ npm install -g solo
$ echo "(def square (function (x) (* x x))) (console.log (square 5))" > test.sl
$ solo test.sl

'use strict';
let square = function (x) {
      return x * x;
};
console.log(square(5));

$ solo test.sl | node --harmony
