babel-plugin-better-trim

Tired of regular boring String.prototype.trim() function? Would you like your trim to trim anything, not just whitespaces? You've come to the right place!

How does it work?

During compilation __better_trim__ function is put at the top of the output. Usages of String.prototype.trim() that have at least 1 argument are replaced with __better_trim__.

Is it useful?

Probably not, I would recommend just using lodash.trim instead. Nevertheless, I wanted to play a little bit with writing babel plugins and this seemed like a good place to start.

Example

In

const s = "0002112300".trim("0");

Out

function __better_trim__(str, chars) {
  if (typeof chars !== "string") {
    return str.trim();
  }var regex = new RegExp("^(" + chars + ")+|(" + chars + ")+$", "g");return str.replace(regex, '');
}const s = __better_trim__("0002112300", "0");

Installation

$ npm install babel-plugin-better-trim

{
  "plugins": ["better-trim"]
}

Via CLI

$ babel --plugins better-trim script.js
