@see inspiration & credits below for more info.

Requirements

  • PHP 5.3
  • Composer

Install

Flux is available as a package via composer

  • 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: )


@Example

This simple example illustrates the way you would use flux and it's fluent interface to build complex patterns.

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.

FLUX API

The flux API was designed to give you a fluent chainable object to build patterns with.

startOfLine()

Adds a beginning of line ^ modifier

endOfLine()

Adds an end of line $ modifier

find( $val ) & then( $val )

Allows you to augment the pattern with a required segment and it escapes regular expression characters

maybe( $val )

Allows you to augment the pattern with an optional segment

any( $val ) & anyOf( $val )

Allows you to create a set of characters to match

anything()

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

anythingBut( $val )

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

br() & lineBreak()

Allows you to match a new line (DOS/Unix)

tab()

Adds a (\t) to the pattern which will match a tab

word()

Adds (\w+) to the pattern which will match a single word

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

Only matches characters in the alphabet and uses $min and $max to create a quantifier

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

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

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

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

orTry( $val='' )

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

ignoreCase() & inAnyCase()

Adds the i modifier to the pattern which will allow you to match in a case insensitive manner

matchNewLine() & dotAll()

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

multiline()

Adds the m modifier to the pattern which will allow you to search across multiple lines

oneLine() & searchOneLine()

Removes the modifier added by multiline() if it was previously called

match( $subject )

Simply takes your $subject in, compares it against the pattern, and returns whether a it matched or not

replace( $replacement, $subject )

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

getPattern()

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

clear()

Clears the created pattern along with the modifiers, prefixes, and suffixes


Flux Elsewhere

There is a straight port of Flux for NodeJS by James Brooks whom has also collaborated on this project.

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!

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

Contributing

  1. Check for open issues or open a new issue for a feature request or a bug
  2. Fork this repo to start making your changes to the dev branch or branch off
  3. Write a test which shows that the bug was fixed or that the feature works as expected
  4. Send a pull request and bug me until I merge it or tell you no cigar; )

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.

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

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

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.

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; )
