A `Set` where an order of elements matters or an `OrderedCollection` with no duplicates. Supports the complete API of `Set` and `OrderedCollection`.

## Installation

To install `CTOrderedSet`, go to the Playground (`Ctrl+OW`) in your [Pharo](https://pharo.org/) image and execute the following Metacello script (select it and press Do-it button or `Ctrl+D`):

```Smalltalk

Metacello new

  baseline: 'ContainersOrderedSet';

  repository: 'github://pharo-containers/Containers-OrderedSet/src';

  load.

```

## How to depend on it?

If you want to add a dependency on OrderedSet to your project, include the following lines into your baseline:

```Smalltalk

spec

  baseline: 'ContainersOrderedSet'

  with: [ spec repository: 'github://pharo-containers/Containers-OrderedSet/src' ].

```

To read more about baselines and Metacello, check out the [Baselines](https://github.com/pharo-open-documentation/pharo-wiki/blob/master/General/Baselines.md) article on [Pharo Wiki](https://github.com/pharo-open-documentation/pharo-wiki).

## How to use it?

`CTOrderedSet` has the same API as `OrderedCollection`, extended with the methods of `Set`. So instance creation looks the same:

```Smalltalk

firstBasket := CTOrderedSet withAll: #(apple apple orange banana orange banana).

secondBasket := CTOrderedSet withAll: #(banana apple banana banana). 

```

Or you can use the `asOrderedSet` method:

```Smalltalk

firstBasket := #(apple apple orange banana orange banana) asOrderedSet.

secondBasket := #(banana apple banana banana) asOrderedSet. 

```
