README
Use Regular Expressions to generate text strings can be used in the following situations:
- Wrting test data for web forms.
- Writing test data for databases.
- 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
- Escape all meta-characters i.e. if you need to escape the character in a regex you will need to escape here.
- Not all meta-characters are suppported see list below.
- Use \X{####}to specify unicode value use[\X{####}-\X{####}]to specify range.
- Unicdoe \pnot supported, I could not find a port of UCD to php, maybe in the future support be added.
- Quantifiers are applied to left most group, literal or character class.
- Beware of the +and*quantifers they apply a possible maxium number of occurances up toPHP_INT_MAX.
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 |
