# CQL (Cucumber Query Language)

CQL is a domain specific language used for querying a Cucumber (or other Gherkin based) test suite. It is written 
in Ruby and powered by the [cuke_modeler](https://github.com/enkessler/cuke_modeler) gem. The goal of CQL is to increase the ease with which 
useful information can be extracted from a modeled test suite and turned into summarized data or reports.

Some uses for example are:

* Build systems
* Reporting

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'cql'
```

And then execute:

$ bundle

Or install it yourself as:

$ gem install cql

## Usage

* Create a new ruby file and require the gem

require 'cql'

* Start querying things!

The first thing that needs to be done is to create a CQL Repository. This can be done with the following line:

require 'cql'
    cql_repo = CQL::Repository.new "/path-to/my/feature-files"

Repositories can also be created from an existing model:

directory = CukeModeler::Directory.new("/path-to/my/feature-files")
    cql_repo = CQL::Repository.new(directory)

Now that you have a repository you can write a query. A simple example is given below

cql_repo.query do
        select name, source_line
        from features
    end

This will return a list of all of the feature names and source lines in the form of a list of hashes.

[{'name' => 'Feature 1', 'source_line' => 1},
     {'name' => 'Feature 2', 'source_line' => 3},
     {'name' => 'Feature 3', 'source_line' => 10}]

Alternatively, you can activate the extensions to the `cuke_modeler` gem and query models directly:

require 'cql'
    require 'cql/model_dsl'
    
    directory = CukeModeler::Directory.new("/path-to/my/feature-files")

directory.query do
        select name, source_line
        from features
    end

For more information on the query options, see the documentation [here](https://github.com/enkessler/cql/tree/master/testing/cucumber/features).
