I'm non-technical, how do I contribute?

If you're non-technical, there are still many ways to contribute.

• You can contribute your voice to the Mozilla Open Voice Project​

• You can give us feedback on this documentation, using the ratings system you'll see at the bottom of the page

• You can contact us and provide suggestions for improvement or enhancement

• You can join our community through our Chat or Forum​

I'm technically minded, how do I contribute?

Great! Let's get you started.

Reporting Issues

• You'll need a GitHub account​

• We require that all developers sign a Contributor License Agreement Request Form. This agreement clarifies that you are granting a license to the Mycroft Project to freely use your work. Additionally, it establishes that you retain the ownership of your contributed code and intellectual property. As the owner, you are free to use your code in other work, obtain patents, or do anything else you choose with it.

• Check our Issues first to see if the Issue has already been reported.

If not, you'll need to create a new Issue. Help us to help fix the Issue quicker by following these guidelines. Your Issue should contain:

A description of the Issue in object-deviation format

Object-deviation format is a very specific way of describing faults. The more specific you can be, the easier it is for us to fix the fault. Begin with the object, such as function, a skill, or a hardware feature, then explain the deviation from the expected condition.

For example:

• "When my Mycroft Mark 1 device (object) powers on, the color of his eyes is red instead of blue (deviation - red - from expected condition - blue)

• "When I ask Mycroft about the weather (object), Mycroft reports the low temperature correctly, but the high temperature is incorrectly reported as the low temperature (deviation - incorrect temperature - from expected condition - correct temperature

The Enclosure or Device you are using, and the version of Mycroft you are using

Be sure to let us know the Enclosure or Device you're using, such as:

• Mark 1

• Mycroft for Linux (please let us know your distro and install method)

• Picroft (let us know which Speakers and Headphones you're using too)

This helps us to pinpoint the issue quickly.

Below, you'll find instructions to identify the version of Mycroft you're using.

Mark 1 and Picroft

To find what version of Mycroft your Mark 1 or Picroft is running, you'll need to SSH into the Device. Run the command apt list

then look through it to find the Mycroft packages that are installed.

mycroft-core/unknown,now 0.9.7 armhf [installed,automatic]
mycroft-mark-1/unknown,now 0.9.7 armhf [installed]
mycroft-picroft/unknown 0.9.7 armhf
mycroft-wifi-setup/unknown,now 0.1.5 armhf [installed,automatic]

Mycroft for Linux

If you're using Mycroft for Linux, you will simply run the CLI, and the CLI will tell you the version number.

mycroft-core$ ./start-mycroft.sh debug

Starting all mycroft-core services
Initializing...
Starting background service bus
Restarting: skills
Restarting: audio
Starting background service voice
Starting cli

The version number will be shown in the top right hand corner of the CLI, as shown below.

Making changes

1. ​Fork the Project​

2. ​Create a new Issue if one doesn't already exist.

3. Create a feature or bugfix branch based on dev with your issue identifier. For example, if your issue identifier is: issue-123 then you will create either: feature/issue-123 or bugfix/issue-123. Use feature prefix for issues related to new functionalities or enhancements and bugfix in case of bugs found on the dev branch

4. Make sure you stick to the coding style and OO patterns that are used already.

5. Document code using Google-style docstrings. Our automated documentation tools expect that format. All functions and class methods that are expected to be called externally should include a docstring. (And those that aren't should be prefixed with a single underscore).

6. Make commits in logical units and describe them properly. Use your issue identifier at the very begin of each commit. For instance:

   git commit -m "Issues-123 - Fixing 'A' sound on Spelling Skill"

7. Before committing, format your code following the PEP8 rules and organize your imports removing unused libs. To check whether you are following these rules, install pep8 and run pep8 mycroft test while in the mycroft-core folder. This will check for formatting issues in the mycroft and test folders.

8. Once you have committed everything and are done with your branch, you have to rebase your code with dev. Do the following steps:

   1. Make sure you do not have any changes left on your branch

   2. Checkout on dev branch and make sure it is up-to-date

   3. Checkout your branch and rebase it with dev

   4. Resolve any conflicts you have

   5. You will have to force your push since the historical base has changed

   6. Suggested steps are:

      git checkout dev
      git fetch
      git reset --hard origin/dev
      git checkout <your_branch_name>
      git rebase dev
      git push -f

9. If possible, create unit tests for your changes

   • ​Unit Tests for most contributions​

   • ​Intent Tests for new skills​

   • We utilize TRAVIS-CI, which will test each pull request. To test locally you can run: ./start.sh unittest

10. Once everything is OK, you can finally create a Pull Request (PR) on Github in order to be reviewed and merged.

Note: Even if you have write access to the master branch, do not work directly on master!

Submitting changes for review

• Push your changes to a topic branch in your fork of the repository.

• Open a pull request to the original repository and choose the right original branch you want to patch.

  Advanced users may install the hub gem and use the hub pull-request command.

• If not done in commit messages (which you really should do) please reference and update your issue with the code changes. But please do not close the issue yourself.

• Even if you have write access to the repository, do not directly push or merge pull-requests. Let another team member review your pull request and approve.
