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.
