split-css

Split css files into arrays that you can use to set prefixes.

exposition

By splitting a css file in just the right places:

var css = [".","title.","today {\n    font-weight: bold;\n}\n\n.","body {\n    font-size: 14px;\n}"]

it's possible to set css prefixes with only a single .join():

var output = css.join('PREFIX-')
console.log(output);

---

.PREFIX-title.PREFIX-today {
    font-weight: bold;
}

.PREFIX-body {
    font-size: 14px;
}

Having css files split into arrays like this is useful for browser experiments where you need to set prefixes for entire css files dynamically but don't want to bundle an entire css parser browser-side.

example

var split = require('../');
var fs = require('fs');
 
var src = fs.readFileSync(__dirname + '/style.css', 'utf8');
var chunks = split(src);
console.dir(chunks);

---

[ '.',
  'body {\n    color: green;\n    padding: 15px;\n}\n\ndiv#',
  'robots .',
  'beep.',
  'boop {\n    text-align: center;\n}\n\n#',
  'a.',
  'b > .',
  'bling.',
  'blong {\n    margin: auto;\n}\n\na.',
  'clickable[href="/x.y.z"]:link, a.',
  'clickable[href="/x.y.z"]:visited {\n    color: cyan;\n}\n' ]
