Goal
----

[](#goal)

*Convenient* and *safe* way to work with collections.

...And it's been (more or less) solved by some other libraries, like [nikic/iter](https://github.com/nikic/iter), [doctrine/collections](https://github.com/doctrine/collections) or even [php-ds/php-ds](https://github.com/php-ds/polyfill). That's why the current version of the library contains just a few helpers for that libraries, to conveniently integrate them together.

Installation
------------

[](#installation)

```
composer require alexeyshockov/colada:~3.0

```

Usage
-----

[](#usage)

The library's functions are split by namespaces, one namespace = specific function a dependency (in most cases).

### `\Colada\ds\{group_by}`

[](#coladadsgroup_by)

Helpers from this namespace require [php-ds/php-ds](https://github.com/php-ds/polyfill) to be available.

`group_by()` function prodices a two dimension array (`\ArrayObject` or `\Ds\Map`, depends on the group key type), from an iterable based on a group function.

```
TODO
```

### `\Colada\GuzzleHttp\{coroutine_invoke, coroutine, time_sleep}`

[](#coladaguzzlehttpcoroutine_invoke-coroutine-time_sleep)

### `\Colada\React\{coroutine_invoke, coroutine}`

[](#coladareactcoroutine_invoke-coroutine)

Helpers from this namespace require [guzzlehttp/promises](https://github.com/guzzle/promises) or [react/promise](https://github.com/reactphp/promise) to be available.

This is the same concept applied to two most popular libs with async capabilities. If you are familiar with async/await in C# or node.js or coroutines in Go, this should be simple. Take a look at the script, written in callback-style and in coroutine-style:

```
TODO
```

```
TODO
```

### `\Colada\iter\opt\{get, head, last, find_one}`

[](#coladaiteroptget-head-last-find_one)

Helpers from this namespace require [phpoption/phpoption](https://github.com/schmittjoh/php-option) to be available.

### `\Colada\iter\{to_kv_pairs, each_n_and_last, uasort, uksort}`

[](#coladaiterto_kv_pairs-each_n_and_last-uasort-uksort)

Simple helpers for general `iterable` types.

`uasort()` and `uksort()` are basically equivalents for the internal ones, but work for arbitrary `iterable` type.

Contributing
------------

[](#contributing)

### Running Tests

[](#running-tests)

To run all the tests, install the vendors (with Composer) and execute:

```
vendor/bin/phpunit --testdox

```

### Public API

[](#public-api)

All classes or functions that are intended to be used by a user should be marked with `@api` PHPDoc tag. Anything without this mark are internal and should not be used by the end user (no guarantees that the interface will stay the same between versions).
