# Trackler

The data for the exercises in for all of the Exercism language tracks, along with the code to sew it all together.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'trackler'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install trackler

## Usage

To access a language track, use the track id (e.g. `ruby`, `cpp`):

```
track = Trackler.tracks["fsharp"]
track.language
# => "F#"
```

Tracks have implementations of specific problems:

```
track.implementations.each do |implementation|
  # implementation.files, implementation.readme, etc
end
```

To get a problem, use the problem slug:

```
problem = Trackler.problems["leap"]
```

Problems contain the generic, language-independent metadata:

```
problem.blurb
# => "Write a program that will take a year and report if it is a leap year."
problem.name
# => "Leap"
```

You can get all of the different language implementations for a problem:

```

Trackler.implementations[problem.slug].each do |implementation|
  # ...
end
```
