Warning: Note that this is most likely not the project you are looking for.
openHAB mainly consist out of the core components and extensions that are from https://github.com/openhab/openhab-addons. All is then packaged into a distribution in https://github.com/openhab/openhab-distro.
We are always thrilled to receive pull requests, and do our best to process them as fast as possible. Not sure if that typo is worth a pull request? Do it! We will appreciate it.
If your pull request is not accepted on the first try, don't be discouraged! If there's a problem with the implementation, hopefully you received feedback on what to improve.
We're trying very hard to keep openHAB lean and focused. We don't want it to do everything for everybody. This means that we might decide against incorporating a new feature. However, there might be a way to implement that feature on top of openHAB.
We recommend discussing your plans in the discussion forum before starting to code - especially for more ambitious contributions. This gives other contributors a chance to point you in the right direction, give feedback on your design, and maybe point out if someone else is working on the same thing.
Fork the repo and make changes on your fork in a feature branch:
- If it's a bugfix branch, name it XXX-something where XXX is the number of the issue
- If it's a feature branch, create an enhancement issue to announce your intentions, and name it XXX-something where XXX is the number of the issue.
Submit unit tests for your changes. openHAB has a great test framework built in; use it! Take a look at existing tests for inspiration. Run the full test suite on your branch before submitting a pull request.
Update the documentation when creating or modifying features. Test your documentation changes for clarity, concision, and correctness, as well as a clean documentation build.
Write clean code. Universally formatted code promotes ease of writing, reading, and maintenance.
Pull requests descriptions should be as clear as possible and include a reference to all the issues that they address.
Pull requests must not contain commits from other users or branches.
Commit messages must start with a capitalized and short summary (max. 50 chars) written in the imperative, followed by an optional, more detailed explanatory text which is separated from the summary by an empty line.
Code review comments may be added to your pull request. Discuss, then make the suggested modifications and push additional commits to your feature branch. Be sure to post a comment after pushing. The new commits will show up in the pull request automatically, but the reviewers will not be notified unless you comment.
Before the pull request is merged, make sure that you squash your commits into
logical units of work using git rebase -i and git push -f. After every
commit the test suite should be passing. Include documentation changes in the
same commit so that a revert would remove all traces of the feature or fix.
Commits that fix or close an issue should include a reference like Closes #XXX
or Fixes #XXX, which will automatically close the issue when merged.
Add your name to the AUTHORS file, but make sure the list is sorted and your name and email address match your git configuration. The AUTHORS file is regenerated occasionally from the git commit history, so a mismatch may result in your changes being overwritten.
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below (from developercertificate.org):

(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that

then you just add a line to every git commit message:
Signed-off-by: Joe Smith <joe.smith@email.com> (github: github_handle)
using your real name (sorry, no pseudonyms or anonymous contributions.)
There are several exceptions to the signing requirement. Currently these are:
- Your patch fixes spelling or grammar errors.
- Your patch is a single line change to documentation.
We want to keep the openHAB community awesome, growing and collaborative. We need your help to keep it that way. To help with this we've come up with some general guidelines for the community as a whole:
-
Be nice: Be courteous, respectful and polite to fellow community members: no regional, racial, gender, or other abuse will be tolerated. We like nice people way better than mean ones!
-
Encourage diversity and participation: Make everyone in our community feel welcome, regardless of their background and the extent of their contributions, and do everything possible to encourage participation in our community.
