OTB Job Queuer

Welcome to your new gem from OTB! It is a job queuer and can be user on the terminal or a Gem in your projects. The gem takes in a string in the format of:

a =>
b => c
c =>

or

a => \nb => \nc => c

And respondes with an ordered sequence of the jobs that takes into accoun the dependecies. For example in this case: a, c, b

Read usage to see how to call methods.

Installation

Add this line to your application's Gemfile:

gem 'OTB-test'

And then execute:

$ bundle

Or install it yourself as:

$ gem install OTB-test

Usage

The usage of the gem methods is the same in terminal or in project.

You can also run the tests to see everything is passing! Skip to section ##Test to do this.

Queue Class Usage

The purpose of this class is to create queues and then sort them. As such there are two public methods:

  • Initialization with new and
  • sorting according to dependecies sort_sequence on a Queue object

Creating a new Queue

  OTB::Queue.new(string: 'a =>')

returns:

  => #<OTB::Queue:0x00007f8433d04260 @jobs="a =>", @jobs_parsed={"a"=>""}>

An OTB::Queue with @jobs and @jobs_parsed available

Sorting a Queue

  new_queue = OTB::Queue.new(string: 'a =>')
  new_queue.sort_sequence

returns:

  => "a"

A string witht the sequence of the jobs ordered.

Job Class - Currently only parse implemented

Job Class exists to parse strings of jobs into Hashes of jobs with dependencies. Further releases will allow you to store individial job objects and create several from a string.

Parsing jobs

  OTB::Job.parse('a => \nb => \nc =>')

returns:

  => {"a"=>"", "b"=>"", "c"=>""}

A Hash with keys being the jobs and values the dependencies.

Loading to terminal

From terminal open your ruby console:

$ irb

Then load the file lib/otb.rb:

$ pry(main)> load 'lib/otb.rb'

It should return true.

Then you can:

$ pry(main)>  OTB::Queue.new(string: 'a =>').sort_sequence

Testes

There are 17 test.

  • 8 testing the Job class, mostly the parse method.
  • 9 testing the Queue class, checking that exections are raised and that the queuer

Inside the OTB-test directory execute:

$ rake spec

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
