String leading whitespaces

pipe-tag-es6-tpl-string.js

// Strip margin (Leading whitespaces)

function pipeFactory( separator = ' ' ){
  return (s, ...args) => {
    return s
      .map(( v, i ) => v + ( args[i] || '') )
      .join('')
      .replace(/(\r\n|\r|\n)([\s]+)?\|/g, separator)
    ;
  };
}

const pipe = pipeFactory();
const pipeml = pipeFactory('\n');


const a = 5;
const b = 10;
const c = 15;

// test normal pipe
console.log(pipe`test normal:
      |test${a}
      |test${b}
|test${c}
test`)

// test pipe multiline
console.log(pipeml`test multiline:
      |test${a}
      |test${b} test${c}
test`)

Fantastic. Good job!

I'm going to fork it and use it in production
