Want to hack on Flows Builder? Awesome! Here are instructions to get you started. They are similar to those of openHAB itself.
Please report Flows Builder specific issues here, while issues that are related to openHAB2 or Eclipse SmartHome should be reported in the openHAB2 GitHub repository or the Eclipse SmartHome repository, respectively. Do not worry, if you are not clear, which category your issue belongs to - we will redirect you, if necessary.
It is assumed you have npm, bower and gulp available; if not,
check their respective docs.
To build the Javascript part of Flows Builder, navigate to the web/ subfolder, then:
- Run
npm install - Run
bower install - Run
gulp
Files in the vendor/ directory should be rebuilt with the above operations.
(note: if adding a new dependency, never add it directly to the project,
add it as a bower and/or npm dependency and rebuild the project using the
instructions above! You would have to modify the targets in gulpfile.js as well)
You also need to set up an openHAB development environment. For instructions on doing so, please refer to the IDE setup guide.
Once it's done:
- Package a new version of the bundle using Maven (
mvn clean packageor use m2e) - Copy the resulting
target/org.openhab.ui.flowsbuilder.{VERSION}.jarinto your server'saddonssubfolder to test it.
If everything went well, push your branch to GitHub, create a pull request and request a merge approval - see instructions below.
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.
Any significant improvement should be documented as a GitHub issue before anybody starts working on it.
Please take a moment to check that an issue doesn't already exist documenting your bug report or improvement proposal. If it does, it never hurts to add a quick "+1" or "I have this problem too". This will help prioritize the most common problems and requests.
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.
openHAB maintainers use LGTM (Looks Good To Me) in comments on the code review to indicate acceptance.
A change requires LGTMs from an absolute majority of the maintainers of each
component affected. For example, if a change affects docs/ and addons/, it
needs an absolute majority from the maintainers of docs/ AND, separately, an
absolute majority of the maintainers of addons/.
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):
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(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
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
then you just add a line to every git commit message:
Signed-off-by: Joe Smith <[email protected]> (github: github_handle)
using your real name (sorry, no pseudonyms or anonymous contributions.)
One way to automate this, is customise your get commit.template by adding
a prepare-commit-msg hook to your openHAB checkout:
curl -L -o .git/hooks/prepare-commit-msg https://raw.github.com/openhab/openhab2/master/contrib/prepare-commit-msg.hook && chmod +x .git/hooks/prepare-commit-msg
- Note: the above script expects to find your GitHub user name in
git config --get github.user
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.
- Step 1: learn the component inside out
- Step 2: make yourself useful by contributing code, bugfixes, support etc.
- Step 3: volunteer on the discussion group or on GitHub
Don't forget: being a maintainer is a time investment. Make sure you will have time to make yourself available. You don't have to be a maintainer to make a difference on the project!
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.
-
Keep it legal: Basically, don't get us in trouble. Share only content that you own, do not share private or sensitive information, and don't break the law.
-
Stay on topic: Make sure that you are posting to the correct channel and avoid off-topic discussions. Remember when you update an issue or respond to an email you are potentially sending to a large number of people. Please consider this before you update. Also remember that nobody likes spam.
