plazy
=====

[](#plazy)

Another functional library for PHP 7.

Quickstart
----------

[](#quickstart)

To use *plazy* in your projects install *composer* and add to your *composer.json* file:

```
"require": {
    "mpstyle/plazy": "0.2.3"
}
```

Or run:

```
composer require "mpstyle/plazy"

```

Sequence
--------

[](#sequence)

The sequence class allows you to build up a computation out of smaller operations. It's similar to Java 8 Streams

Now we can try some of the following:

```
Sequence::sequence(1, 2, 3, 4)->filter(even); // lazily returns 2,4
Sequence::sequence(1, 2)->map(toString); // lazily returns "1", "2"
Sequence::sequence(1, 2, 3)->take(2); // lazily returns 1,2
Sequence::sequence(1, 2, 3)->drop(2); // lazily returns 3
Sequence::sequence(1, 2, 3)->tail(); // lazily returns 2,3
Sequence::sequence(1, 2, 3)->head(); // eagerly returns 1
Sequence::sequence(1, 3, 5)->find(even); // eagerly returns none()
Sequence::sequence(1, 2, 3)->contains(2); // eagerly returns true
Sequence::sequence(1, 2, 3)->toString(":"); // eagerly returns "1:2:3"
```

Option
------

[](#option)

Optional value - type-safe null

Functions
---------

[](#functions)

plazy provides some interfaces for functional uages, such as:

- F: to transform an object to another one.
- Predicate: to filter/select/match an object.
- Validator: to validate an object.

Developers
----------

[](#developers)

To run unit test, run in the root of the plazy project:

```
composer phptest

```
