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; ``` ***Produces*** ``` jmceohykoa aclohnotga jqegzuklcv ixdbpbgpkl kcyrxqqfyw jcxsjrtrqb kvaczmawlz itwrowxfxh auinmymonl dujyzuhoag vaygybwkfm ``` #### Other examples [](#other-examples) 1.

[Mobile numbers](https://github.com/icomefromthenet/ReverseRegex/blob/master/examples/mobilenumbers.php) \##Installing To install use composer ``` { "require" : { "icomefromthenet/reverse-regex" : "dev-master" } } ``` 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 ### Health Score 46 — FairBetter than 93% of packages Maintenance42 Moderate activity, may be stable Popularity51 Moderate usage in the ecosystem Community27 Small or concentrated contributor base Maturity55 Maturing project, gaining track record Bus Factor1 Top contributor holds 96.2% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
