Contributing to Gobot

Target Branch

Please open all non-hotfix PRs against the dev branch!

Gobot follows a "git flow"-style model for managing development.

Issue Contributions

When opening new issues or commenting on existing issues on this repository please make sure discussions are related to concrete technical issues with the Gobot software.

Code Contributions

The Gobot project welcomes new contributors.

This document will guide you through the contribution process.

What do you want to contribute?

  • I want to otherwise correct or improve the docs or examples
  • I want to report a bug
  • I want to add some feature or functionality to an existing hardware platform
  • I want to add support for a new hardware platform

Descriptions for each of these will eventually be provided below.

General Guidelines

  • All active development is in the dev branch. New or updated features must be added to the dev branch. Hotfixes will be considered on the master branch in situations where it does not alter behaviour or features, only fixes a bug.
  • All patches must be provided under the Apache 2.0 License
  • Please use the -S option in git to "sign off" that the commit is your work and you are providing it under the Apache 2.0 License
  • Submit a Github Pull Request to the appropriate branch and ideally discuss the changes with us in IRC.
  • We will look at the patch, test it out, and give you feedback.
  • Avoid doing minor whitespace changes, renamings, etc. along with merged content. These will be done by the maintainers from time to time but they can complicate merges and should be done seperately.
  • Take care to maintain the existing coding style.
  • golint and go fmt your code.
  • Add unit tests for any new or changed functionality.
  • All pull requests should be "fast forward"
    • If there are commits after yours use “git rebase -i <new_head_branch>”
    • If you have local changes you may need to use “git stash”
    • For git help see progit which is an awesome (and free) book on git

Creating Pull Requests

Because Gobot makes use of self-referencing import paths, you will want to implement the local copy of your fork as a remote on your copy of the original Gobot repo. Katrina Owen has an excellent post on this workflow.

The basics are as follows:

  1. Fork the project via the GitHub UI

  2. go get the upstream repo and set it up as the upstream remote and your own repo as the origin remote:

go get gobot.io/x/gobot cd $GOPATH/src/gobot.io/x/gobot git remote rename origin upstream git remote add origin git@github.com/YOUR_GITHUB_NAME/gobot

All import paths should now work fine assuming that you've got the proper branch checked out.

  1. Get all the needed gobot's dependencies each of them at their needed version. Gobot uses dep (Dependency management for Go) to manage the project's dependencies. To get all the correct dependencies:
  • Install dep tool. Follow the dep installation instructions in case you don't have it already installed.
  • cd $GOPATH/src/gobot.io/x/gobot
  • dep ensure will fetch all the dependencies at their needed version.

Landing Pull Requests

(This is for committers only. If you are unsure whether you are a committer, you are not.)

  1. Set the contributor's fork as an upstream on your checkout

git remote add contrib1 https://github.com/contrib1/gobot

  1. Fetch the contributor's repo

git fetch contrib1

  1. Checkout a copy of the PR branch

git checkout pr-1234 --track contrib1/branch-for-pr-1234

  1. Review the PR as normal

  2. Land when you're ready via the GitHub UI
