NooNoo Fluent Regex
=================

# DEPRECEATION

This repo is no longer maintained - I highly recommend you move your code usage over to https://github.com/selvinortiz/flux - it features a very similar API!

# What

Build Regex expressions using fluent setters and English language terms

```php
$regex = new Regex();

//regex for a url
$regex->start()
      ->then("http")
      ->maybe("s")
      ->then("://")
      ->maybe("www.")
      ->oneOrMore()
      ->slugchar()
      ->either(".co", ".com")
      ->zeroOrMore()
      ->slugchar()
      ->end();

echo $regex; // ^(http)(s)?(\:\/\/)(www\.)?([a-zA-Z0-9-_\/]+)(\.co|\.com)([a-zA-Z0-9-_\/]*)$
```

# Examples

#### Exclusive! Build your Regex using _Yorkshire Slang!_

Here's the above example, but this time, a bit more..._~~Northern~~ Better_

```php
$regex->eyUp()
      ->goOnThen("http")
      ->couldAppen("s")
      ->goOnThen("://")
      ->couldAppen("www.")
      ->oneOrMore()
      ->slugchar()
      ->oneOrTother(".co", ".com")
      ->zeroOrMore()
      ->slugchar()
      ->thatllDo();
```

### Finding Matches

We can use the `Match` class to return capture groups for an input and a Regex pattern (as well as checking that the pattern matches the text, obviously)

__Simple Match__

```php

$regex = new Regex();

$regex->start()
        ->then("Hello, ")
        ->then("world!")
        ->end();

$match = new Match("Hello, world!", $regex);

$match->isMatch(); // returns true

//thanks to invoke, you can also just check against the object itself

//ex. this returns true
if ($match)
    return true;
else
    return false;
```

If you build your pattern using a NooNooFluentRegex Regex object, each "chunk" that could contain characters will be its own capture group.

```php
$regex->start()
      ->then("http")
      ->maybe("s")
      ->then("://")
      ->maybe("www.")
      ->oneOrMore()
      ->slugchar()
      ->either(".co", ".com")
      ->zeroOrMore()
      ->slugchar()
      ->end();

$match = new Match("http://www.example.com/example_page", $regex);

echo $match->getGroup(5); // echos "example"
```
You can also return groups using specified names

```php
$regex = new Regex();

$regex->start()
    ->lowercase("lowercase")
    ->uppercase("uppercase")
    ->raw("[A-Z][a-z]+", "name")
    ->digit("number1")
    ->digit("number2") // number 2...hehehehe
    ->end();

$match = new Match("aZTom69", $regex);

echo $match->getGroup("name"); // echos "Tom"
echo $match->getGroup("uppercase"); // echos "Z"

```
### Doing Replacements

We can use the Replacer class to do both mass replacements and individual, case-by-case replacements.

```php

$regex = new Regex();

$regex->start()
        ->raw("[A-Z][a-z]+")
        ->end();

//we set up the replacer with a pattern, and a replacement to use
$replacer = new Replacer($regex, "Tom");

//now that those 2 are set up, you can start doing mass replacements

echo $replacer->replace("Sam went to play football"); //echos out "Tom went to play football";
echo $replacer->replace("Dave goes to the shop"); //echos out "Tom goes to the shop";
```

You can pass in an optional argument to the replace function to do case by case replacements.

```php
//using the same variables as before

echo $replacer->replace("Martin plays too much Starcraft", "Sally"); // "Sally plays too much Starcraft"
echo $replacer->replace("Martin plays too much Starcraft"); // "Tom plays too much Starcraft"
```
