Code of Conduct

In order to have a more open and welcoming community, Classifier Reborn adheres to the Jekyll code of conduct adapted from the Ruby on Rails code of conduct.

Please adhere to this code of conduct in any interactions you have in the Classifier community. If you encounter someone violating these terms, please let Chase Gilliam know and we will address it as soon as possible.

Development Environment

To make changes in the gem locally clone the repository or your fork.

$ git clone
$ cd classifier-reborn
$ bundle install
$ gem install redis
$ rake                       # To run tests

Some tests should be skipped if the Redis server is not running on the development machine. To test all the test cases first install Redis then run the server and perform tests.

$ redis-server --daemonize yes
$ rake                       # To run tests
$ rake bench                 # To run benchmarks
$ rake validate              # To run validations

Kill the redis-server daemon when done.

Development Using Docker

Provided that Docker is installed on the development machine, clone the repository or your fork. From the directory of the local clone build a Docker image locally to setup the environment loaded with all the dependencies.

$ git clone
$ cd classifier-reborn
$ docker build -t classifier-reborn .

To run tests on the local code (before or after any changes) mount the current working directory inside the container at /usr/src/app and run the container without any arguments. This step should be repeated each time a change in the code is made and a test is desired.

$ docker run --rm -it -v "$PWD":/usr/src/app classifier-reborn

A rebuild of the image would be needed only if the Gemfile or other dependencies change. To run tasks other than test or to run other commands access the Bash prompt of the container.

$ docker run --rm -it -v "$PWD":/usr/src/app classifier-reborn bash
root@[container-id]:/usr/src/app# redis-server --daemonize yes
root@[container-id]:/usr/src/app# rake                       # To run tests
root@[container-id]:/usr/src/app# rake bench                 # To run benchmarks
root@[container-id]:/usr/src/app# rake validate              # To run validations
root@[container-id]:/usr/src/app# pry
[1] pry(main)> require 'classifier-reborn'
[2] pry(main)> classifier = 'Ham', 'Spam'


To make changes to this documentation and to run it locally, run a Docker container with the following command.

$ docker run --rm -it -v "$PWD":/usr/src/app -w /usr/src/app/docs -p 4000:4000 classifier-reborn jekyll s -H

If the server runs as expected then the documentation should be available at http://localhost:4000/.
