README
REBuilder is a PHP 5.3+ library to build and parse regular expressions
Installation
Include the following requirement to your composer.json:
{
"require": {
"mck89/rebuilder": "dev-master"
}
}
Run composer install
and include the autoloader:
require_once "vendor/autoload.php";
Parse
REBuilder's parser builds a tree structure starting from a regular expression. For example this code:
//Parse the regular expression $regex = REBuilder\REBuilder::parse("/parse\s+me/");
Generates this structure:
REBuilder\Pattern\Regex
getStartDelimiter() => "/"
getEndDelimiter() => "/"
getChildren() => array(
REBuilder\Pattern\Char
getChar() => "parse"
REBuilder\Pattern\GenericCharType
getIdentifier() => "s"
getRepetition() => REBuilder\Pattern\Repetition\OneOrMore
REBuilder\Pattern\Char
getChar() => "me"
)
Build
REBuilder allows you to build regular expressions with object oriented PHP:
//Create an empty regular expression object $regex = REBuilder\REBuilder::create(); $regex->addCharAndContinue("parse") ->addGenericCharType("s") ->setRepetition("+") ->getParent() ->addCharAndContinue("me"); echo $regex->render(); //"/parse\s+me/"
