FLUX (Fluent Regex) 0.5.2

, _(*1)

by Selvin Ortiz, _(*2)

Description

Fluent Regular Expressions in PHP inspired by and largely based on VerbalExpressions:JS by Jesse Luoto, _(*3)

@see inspiration & credits below for more info., _(*4)

Requirements

PHP 5.3
Composer

Install

Flux is available as a package via composer, _(*5)

require: "selvinortiz/flux": "dev-master"
autoload: require_once 'path/to/vendor/autoload.php'
namespace: use SelvinOrtiz\Utils\Flux\Flux;
instantiate: $flux = Flux::getInstance();

You can additionally clone/download this repo and do whatever you want: ), _(*6)

@Example

This simple example illustrates the way you would use flux and it's fluent interface to build complex patterns., _(*7)

require_once realpath(__DIR__.'/../vendor/autoload.php');

use SelvinOrtiz\Utils\Flux\Flux;
use SelvinOrtiz\Utils\Flux\Helper;

// The subject string (URL)
$str    = 'http://www.selvinortiz.com';

// Building the pattern (Fluently)
$flux   = Flux::getInstance()
        ->startOfLine()
        ->find('http')
        ->maybe('s')
        ->then('://')
        ->maybe('www.')
        ->anythingBut('.')
        ->either('.co', '.com')
        ->ignoreCase()
        ->endOfLine();

// Output the Flux instance
Helper::dump( $flux );

// Output the fluently built pattern (@see /src/SelvinOrtiz/Utils/Flux/Helper)
Helper::msg( $flux ); // /^(http)(s)?(\:\/\/)(www\.)?([^\.]*)(.co|.com)$/i

// Inspect the results
Helper::msg( $str );
Helper::msg( $flux->match( $str ) ? 'matched' : 'unmatched' );
Helper::msg( $flux->replace( 'https://$5$6', $str ) );

For other examples, please see the /etc directory., _(*8)

FLUX API

The flux API was designed to give you a fluent chainable object to build patterns with., _(*11)

`startOfLine()`

Adds a beginning of line ^ modifier, _(*12)

`endOfLine()`

Adds an end of line $ modifier, _(*13)

`find( $val ) & then( $val )`

Allows you to augment the pattern with a required segment and it escapes regular expression characters, _(*14)

`maybe( $val )`

Allows you to augment the pattern with an optional segment, _(*15)

`any( $val ) & anyOf( $val )`

Allows you to create a set of characters to match, _(*16)

`anything()`

Adds a wild card (.*) segment to the pattern but it does not make dotAll() explicit, _(*17)

`anythingBut( $val )`

Will match anything but the characters in $val which is opposite of any() and anyOf, _(*18)

`br() & lineBreak()`

Allows you to match a new line (DOS/Unix), _(*19)

`tab()`

Adds a (\t) to the pattern which will match a tab, _(*20)

`word()`

Adds (\w+) to the pattern which will match a single word, _(*21)

`letters( $min=null, $max=null )`

Only matches characters in the alphabet and uses $min and $max to create a quantifier, _(*22)

`digits( $mix=null, $max=null )`

Only matches digits and uses $min and $max to create a quantifier like word(), _(*23)

`range( $from, $to [, $from, $to ...])`

Allows you to create a range character class like a-z0-9 by calling range('a', 'z', 0, 9), _(*24)

`orTry( $val='' )`

Allows you to create OR cases (this)|(else) and retain the capturing order to use in replace(), _(*25)

`ignoreCase() & inAnyCase()`

Adds the i modifier to the pattern which will allow you to match in a case insensitive manner, _(*26)

`matchNewLine() & dotAll()`

Adds the s modifier to the pattern which will allow you to match a new line when using anything(), _(*27)

`multiline()`

Adds the m modifier to the pattern which will allow you to search across multiple lines, _(*28)

`oneLine() & searchOneLine()`

Removes the modifier added by multiline() if it was previously called, _(*29)

`match( $subject )`

Simply takes your $subject in, compares it against the pattern, and returns whether a it matched or not, _(*30)

`replace( $replacement, $subject )`

You can replace matched segments by using the $x format where x is the (int) position of the matched segment, _(*31)

`getPattern()`

Returns the compiled pattern which you can also get by using the flux instance in a context where __toString() will be called, _(*32)

`clear()`

Clears the created pattern along with the modifiers, prefixes, and suffixes, _(*33)

Flux Elsewhere

There is a straight port of Flux for NodeJS by James Brooks whom has also collaborated on this project., _(*34)

Feedback

This is something that started as a weekend experiment but I would love to take it further so if you have any suggestions, please fire away!, _(*35)

The best way to get in touch with me is via twitter @selvinortiz we'll take if from there :), _(*36)

Inspiration & Credits

This project is inspired and largely based on VerbalExpressions:JS by Jesse Luoto whom on July 20, 2013 started a weekend project that generated a lot of interest in the developer community and that project has proven to have a lot of potential., _(*37)

Flux is not a straight port of VerbalExpressions but if you're interested in a straight VerbalExpressions port for PHP you should checkout VerbalExpressions:PHP by Mark Wilson, _(*38)

VerbalExpressions has also been ported to Ruby, Java, Groovy as of this update (July 25, 2013)., _(*39)

For a little background as to why flux was created and why you should use it, please refer to Issue #7 for a discussion on that matter., _(*40)

MIT License

Flux is released under the MIT license which pretty much means you can do with it as you please and I won't get mad because I'm that nice; ), _(*41)
