Compiles an extremely small subset of clojure to JavaScript
npm install clojure-liteDisclaimer: this is a super-immature toy project :bowtie:
clojure-lite compiles an extremely small subset of clojure to JavaScript. That's pretty much all it does. Have fun!
It currently lets you:
- define and refer variables
- define and call functions
Other quirks:
- the standard library is limited to +, -, *, and /
- there's only one type: number
clojure
(def PI 3.141592653589793)
(defn area [radius] (* PI radius radius))
(area 5)
`
is compiled to:
javascript
const __lib = {};
__lib['*'] = function (...args) {
return args.reduce((acc, curr) => acc * curr, 1);
};
let PI = 3.141592653589793;
function area(radius) {
return __lib'*';
}
area(5);
`Usage
Programmatic:sh
$ npm install clojure-lite --save
`
javascript
const cl = require('clojure-lite');const compile = _.compose(
cl.codegen,
cl.parser,
cl.lexer
);
const code = compile('(def answer 42)');
`CLI:
sh
$ npm install -g clojure-lite
`
sh
$ echo '(def answer 42)' | cl > code.js
