rexer

Generate matching strings from regular expressions.

$ npm install rexer [-g]

Usage

rex <pattern[, pattern[, ...]]>
var rex = require('rexer');
var matches = rex(pattern[, pattern[, ...]]);

Arguments are automatically concatenated, so rex a b is equivalent to rex ab. The same applies when used as a module.

Works for

  • literals,
$ rex "abcd"
["abcd"]
  • character sets
$ rex "[a-c][0-2]"
["a0","a1","a2","b0","b1","b2","c0","c1","c2"]
  • and alternations.
$ rex "(hi|bye) world"
["hi world","bye world"]
