RegExpBuilder

RegExpBuilder integrates regular expressions into the programming language, thereby making them easy to read and maintain. Regular Expressions are created by using chained methods and variables such as arrays or strings.

Examples

Here are a couple of examples using Javascript:
var r = require('regexpbuilder');

Money

var regex = r
  .find("$")
  .min(1).digits()
  .then(".")
  .digit()
  .digit()
  .getRegExp();
  
regex.test("$10.00"); // true

Nested patterns

var pattern = r
  .min(1).of("p")
  .min(2).of("q");

var regex = r
  .exactly(2).like(pattern)
  .getRegExp();

regex.test("pqqpqq"); // true

API documentation

RegExpBuilder can represent literally every possible regular expression using methods such as either(), or(), behind(), asGroup() and so on. You can find the API documentation here.
