Regex Combiner

Combines an array of regexes into a single regex.

Example

var regexCombiner = require('regex-combiner');
var combined = regexCombiner([
    /abc$/,
    /abcd+e/,
    /a.*/,
    /bar/,
    'bad+' // strings are accepted too
]);
/* /(a(bc($|d+e)|.*)|ba(r|d+))/ */
 
combined.test('abcdddde'); // true
combined.test('bar'); // true
combined.test('baddd'); // true

Caveats

  • No flags! Combining case-sensitive and case-insensitive regexes is ... difficult, so all flags are ignored.
  • No back-references in the input regexes. Things like /(['"])foo\1/ are just not going to work.
  • The resulting regex is pretty much only going to be useful for .test(). Trying to get something meaningful from the groups is not going to be fun.
