ReverseRegex
============

[](#reverseregex)

[![Build Status](https://camo.githubusercontent.com/9a4e0aa470badc8e8e7f69db199d3948f5e5f2b8b56cd20dd3297dd73c3d420f/68747470733a2f2f7472617669732d63692e6f72672f69636f6d6566726f6d7468656e65742f5265766572736552656765782e706e67)](https://travis-ci.org/icomefromthenet/ReverseRegex)

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;
```

    }
}
```

Writing a Regex
---------------

[](#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](http://www.unicode.org/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`.

### Regex Support

[](#regex-support)

   Example   Description   Resulting String     (abcf)   Support literals this would generate string  `abcf`    \\((abcf)\\)   Escape meta characters as you normally would in a regex  `(abcf)`    \[a-z\]   Character Classes are supported  `a`    a{5}   Quantifiers supported always **last** group or literal or character class  `aaaaa`    a{1,5}   Range Quantifiers supported `aa`    a|b|c   Alternation supported pick one of three at random  `b`    a|(y|d){5}   Groups supported with alternation and quantifiers  `ddddd` or `a` or `yyyyy`      \\d   Digit shorthand equ \[0-9\]  `1`    \\w  word character shorthand equ \[a-zA-Z0-9\_\]  `j`    \\W Non word character shorthand equ \[^a-zA-Z0-9\_\]  `j`    \\s White space shorthand ASCII only  ` `    \\S Non White space shorthand ASCII only  `i`    . Dot all ASCII characters  `$`    \* + ? Short hand quantifiers, recommend not use them       \\X{00FF}\[\\X{00FF}-\\X{00FF}\] Unicode ranges      \\xFF\[\\xFF-\\xFF\]  Hex ranges
