cli usage

Given:

// file: src/example.js
import {asd, boo} from 'asd'
import math from 'somewhere'
const z = 2;
function foo() {
  const x = 3 + z;
  function bla() {
    const f = 5 + asd;
    return x + 1;
  }
  function tada() {
    return x + math.sin(x);
  }
}

Run :

$ purefuncs src/example.js -o test/purefuncs/example.js

Output:

// file: test/purefuncs/example.js
export const foo = ({asd, math, z}) => () => {
  const x = 3 + z;
  function bla() {
    const f = 5 + asd;
    return x + 1;
  }
  function tada() {
    return x + math.sin(x);
  }
}

export const foo$bla = ({asd, x}) => () => {
  const f = 5 + asd;
  return x + 1;
}

export const foo$tada = ({math, x}) => () => {
  return x + math.sin(x);
}
