README

This is a fork of https://github.com/icomefromthenet/ReverseRegex (that provides icomefromthenet/reverse-regex).

Use Regular Expressions to generate text strings can be used in the following situations:

1. Wrting test data for web forms.
2. Writing test data for databases.
3. Generating test data for regular expressions.

##Example

use ReverseRegex\Lexer;
use ReverseRegex\Random\SimpleRandom;
use ReverseRegex\Parser;
use ReverseRegex\Generator\Scope;

# load composer
require "vendor/autoload.php";

$lexer = new  Lexer('[a-z]{10}');
$gen   = new SimpleRandom(10007);
$result = '';

$parser = new Parser($lexer,new Scope(),new Scope());
$parser->parse()->getResult()->generate($result,$gen);

echo $result;

##Installing

Writing a Regex

1. Escape all meta-characters i.e. if you need to escape the character in a regex you will need to escape here.
2. Not all meta-characters are suppported see list below.
3. Use \X{####} to specify unicode value use [\X{####}-\X{####}] to specify range.
4. Unicdoe \p not supported, I could not find a port of UCD to php, maybe in the future support be added.
5. Quantifiers are applied to left most group, literal or character class.
6. Beware of the + and * quantifers they apply a possible maxium number of occurances up to PHP_INT_MAX.
