### Helper traits for enums
Enumerable provides a simple structure of interfaces and traits to unlock the full power of PHP enums.
---
## Installation
Install via Composer:
```bash
composer require decodelabs/enumerable
```
## Usage
Enumerable defines a powerful top level Enum interface that expands the range of functionality enums provide whilst consolidating the same functionality across both UnitEnum and BackedEnum types.
All Enumerable enums implement a type specific interface and use an accompanying trait. Each form dictates a type for a key, value and label property, where the key is used as the index in lists and the label is used for display purposes.
## Unit enums
### Named UnitEnum
```php
use DecodeLabs\Enumerable\Unit\Named;
use DecodeLabs\Enumerable\Unit\NamedTrait;
enum MyNamedUnitEnum implements Named
{
use NamedTrait;
const OptionOne;
const OptionTwo;
const OptionThree;
}
MyNamedUnitEnum::OptionOne->getName(); // 'OptionOne'
MyNamedUnitEnum::OptionOne->getKey(); // 'OptionOne'
MyNamedUnitEnum::OptionOne->getLabel(); // 'Option One'
MyNamedUnitEnum::OptionOne->getValue(); // 'OptionOne'
```
### Indexed UnitEnum
```php
use DecodeLabs\Enumerable\Unit\Indexed;
use DecodeLabs\Enumerable\Unit\IndexedTrait;
enum MyIndexedUnitEnum implements Indexed
{
use IndexedTrait;
const OptionOne;
const OptionTwo;
const OptionThree;
}
MyNamedUnitEnum::OptionOne->getName(); // 'OptionOne'
MyNamedUnitEnum::OptionOne->getKey(); // 0
MyNamedUnitEnum::OptionOne->getLabel(); // 'Option One'
MyNamedUnitEnum::OptionOne->getValue(); // 'OptionOne'
```
## Backed enums
### Named String BackedEnum
```php
use DecodeLabs\Enumerable\Backed\NamedString;
use DecodeLabs\Enumerable\Backed\NamedStringTrait;
enum MyNamedStringBackedEnum : string implements NamedString
{
use NamedStringTrait;
const OptionOne = 'one';
const OptionTwo = 'two';
const OptionThree = 'three';
}
MyNamedStringBackedEnum::OptionOne->getName(); // 'OptionOne'
MyNamedStringBackedEnum::OptionOne->getKey(); // 'OptionOne'
MyNamedStringBackedEnum::OptionOne->getLabel(); // 'Option One'
MyNamedStringBackedEnum::OptionOne->getValue(); // 'one'
```
### Labelled String BackedEnum
```php
use DecodeLabs\Enumerable\Backed\LabelledString;
use DecodeLabs\Enumerable\Backed\LabelledStringTrait;
enum MyLabelledStringBackedEnum : string implements LabelledString
{
use LabelledStringTrait;
const OptionOne = 'one';
const OptionTwo = 'two';
const OptionThree = 'three';
}
MyLabelledStringBackedEnum::OptionOne->getName(); // 'OptionOne'
MyLabelledStringBackedEnum::OptionOne->getKey(); // 'OptionOne'
MyLabelledStringBackedEnum::OptionOne->getLabel(); // 'one'
MyLabelledStringBackedEnum::OptionOne->getValue(); // 'one'
```
### Value String BackedEnum
```php
use DecodeLabs\Enumerable\Backed\ValueString;
use DecodeLabs\Enumerable\Backed\ValueStringTrait;
enum MyValueStringBackedEnum : string implements ValueString
{
use ValueStringTrait;
const OptionOne = 'one';
const OptionTwo = 'two';
const OptionThree = 'three';
}
MyValueStringBackedEnum::OptionOne->getName(); // 'OptionOne'
MyValueStringBackedEnum::OptionOne->getKey(); // 'one'
MyValueStringBackedEnum::OptionOne->getLabel(); // 'Option One'
MyValueStringBackedEnum::OptionOne->getValue(); // 'one'
```
### Named Int BackedEnum
```php
use DecodeLabs\Enumerable\Backed\NamedInt;
use DecodeLabs\Enumerable\Backed\NamedIntTrait;
enum MyNamedIntBackedEnum : int implements NamedInt
{
use NamedIntTrait;
const OptionOne = 1;
const OptionTwo = 2;
const OptionThree = 3;
}
MyNamedIntBackedEnum::OptionOne->getName(); // 'OptionOne'
MyNamedIntBackedEnum::OptionOne->getKey(); // 'OptionOne'
MyNamedIntBackedEnum::OptionOne->getLabel(); // 'Option One'
MyNamedIntBackedEnum::OptionOne->getValue(); // 1
```
### Value Int BackedEnum
```php
use DecodeLabs\Enumerable\Backed\ValueInt;
use DecodeLabs\Enumerable\Backed\ValueIntTrait;
enum MyValueIntBackedEnum : int implements ValueInt
{
use ValueIntTrait;
const OptionOne = 1;
const OptionTwo = 2;
const OptionThree = 3;
}
MyValueIntBackedEnum::OptionOne->getName(); // 'OptionOne'
MyValueIntBackedEnum::OptionOne->getKey(); // 1
MyValueIntBackedEnum::OptionOne->getLabel(); // 'Option One'
MyValueIntBackedEnum::OptionOne->getValue(); // 1
```
## Instantiation
All enum types can be instantiaed with the following methods:
```php
MyEnum::fromKey('');
MyEnum::fromValue('');
MyEnum::fromName('');
MyEnum::fromIndex('');
// or
MyEnum::tryFromKey('');
MyEnum::tryFromValue('');
MyEnum::tryFromName('');
MyEnum::tryFromIndex('');
```
## Lists
Enumerable provides three main ways of listing cases:
```php
// Key to label map
MyEnum::getOptions() => [
'' => '',
];
// Key to value map
MyEnum::getValues() => [
'' => '',
];
// Alias to cases()
MyEnum::getCases() => [
'' => '[MyEnum::]',
];
```
