Contributing#

Contributions are welcome, and they are greatly appreciated! Every little bit helps, and credit will always be given.

You can contribute in many ways:

Types of Contributions#

Report Bugs#

Report bugs at fury-gl/fury#issues.

If you are reporting a bug, please include:

Any details about your local setup that might be helpful in troubleshooting.
Detailed steps to reproduce the bug.

Fix Bugs#

Look through the GitHub issues for bugs. Anything tagged with “bug” is open to whoever wants to implement it.

Implement Features#

Look through the GitHub issues for features. Anything tagged with “feature” is open to whoever wants to implement it.

Write Documentation#

FURY could always use more documentation, whether as part of the official FURY docs, in docstrings, or even on the web in blog posts, articles, and such. FURY uses Sphinx. Please follow the numpy coding style and PEP8 for docstring documentation.

Submit Feedback#

The best way to send feedback is to file an issue at fury-gl/fury#issues.

If you are proposing a feature:

Explain in detail how it would work.
Keep the scope as narrow as possible, to make it easier to implement.
Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!#

Ready to contribute? Here’s how to set up FURY for local development.

Fork the FURY repo on GitHub.

Clone your fork locally:

$ git clone https://github.com/your_name_here/fury.git

Add a tracking branch which can always have the last version of FURY:

$ git remote add fury-gl https://github.com/fury-gl/fury.git
$ git fetch fury-gl
$ git branch fury-gl-master --track fury-gl/master
$ git checkout fury-gl-master
$ git pull

Create a branch from the last dev version of your tracking branch for local development:
```
$ git checkout -b name-of-your-bugfix-or-feature
```
Install it locally:
```
$ pip install --user -e .
```

Now you can make your changes locally:

$ git add .
$ git commit -m "Your detailed description of your changes."
$ git push origin name-of-your-bugfix-or-feature

Install the required packages for running the unittests:

$ pip install -r requirements/optional.txt
$ pip install -r requirements/test.txt

When you’re done making changes, check that your changes pass flake8 and pytest:
```
$ flake8 fury
$ pytest -svv fury
```
To get flake8 and pytest, just pip install them into your virtualenv.
Submit a pull request through the GitHub website.

Pull Request Guidelines#

Before you submit a pull request, check that it meets these guidelines:

The pull request should include tests.
If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.md.
The pull request should work for Python 3.6, 3.7, 3.8, 3.9 and for PyPy. Check fury-gl/fury and make sure that the tests pass for all supported Python versions.

Publishing Releases#

Checklist before Releasing#

Review the open list of FURY issues. Check whether there are outstanding issues that can be closed, and whether there are any issues that should delay the release. Label them !
Check whether there are no build failing on GitHub Actions.
Review and update the release notes. Get a partial list of contributors with something like:
```
git shortlog -nse v0.10.0..
```
where v0.10.0 was the last release tag name.

Then manually go over git shortlog v0.10.0.. to make sure the release notes are as complete as possible and that every contributor was recognized.
Use the opportunity to update the .mailmap file if there are any duplicate authors listed from git shortlog -ns.
Add any new authors to the AUTHORS file.
Check the copyright years in LICENSE
Generate release notes. Go to docs/source/ext and run github_tools.py script the following way:
```
$ python github_tools.py --tag=v0.10.0 --save --version=0.11.0
```
This command will generate a new file named release0.11.0.rst in release_notes folder.
Add in release-history.rst the newly created file release0.11.0.rst.
Check the examples and tutorial - we really need an automated check here.

Make sure all tests pass on your local machine (from the <fury root> directory):

cd ..
pytest -svv --doctest-modules fury
cd fury # back to the root directory

Check the documentation doctests:
```
cd docs
make -C . html
cd ..
```
The release should now be ready.

Doing the release#

Update release-history.rst in the documentation if you have not done so already. You may also highlight any additions, improvements, and bug fixes.
Type git status and check that you are on the master branch with no uncommitted code.
Now it’s time for the source release. Mark the release with an empty commit, just to leave a marker. It makes it easier to find the release when skimming through the git history:
```
git commit --allow-empty -m "REL: vX.Y.Z"
```
Tag the commit:
```
git tag -am 'Second public release' vX.Y.Z  # Don't forget the leading v
```
This will create a tag named vX.Y.Z. The -a flag (strongly recommended) opens up a text editor where you should enter a brief description of the release.
Verify that the __version__ attribute is correctly updated:
```
import fury
fury.__version__  # should be 'X.Y.Z'
```
Incidentally, once you resume development and add the first commit after this tag, __version__ will take on a value like X.Y.Z+1.g58ad5f7, where +1 means “1 commit past version X.Y.Z” and 58ad5f7 is the first 7 characters of the hash of the current commit. The letter g stands for “git”. This is all managed automatically by versioneer and in accordance with the specification in PEP 440.

Push the new commit and the tag to master:

git push origin master
git push origin vX.Y.Z

Register for a PyPI account and Install twine, a tool for uploading packages to PyPI:
```
python3 -m pip install --upgrade twine
```
Remove any extraneous files:
```
git clean -dfx
```
If you happen to have any important files in your project directory that are not committed to git, move them first; this will delete them!
Publish a release on PyPI:
```
python -m build
twine upload dist/*
```
Check how everything looks on pypi - the description, the packages. If necessary delete the release and try again if it doesn’t look right.
Set up maintenance / development branches

If this is this is a full release you need to set up two branches, one for further substantial development (often called ‘trunk’) and another for maintenance releases.
- Branch to maintenance:
```
git co -b maint/X.Y.Z
```
  Push with something like git push upstream-rw maint/0.6.x --set-upstream
- Start next development series:
```
git co main-master
```
  Next merge the maintenance branch with the “ours” strategy. This just labels the maintenance branch info.py edits as seen but discarded, so we can merge from maintenance in future without getting spurious merge conflicts:
```
git merge -s ours maint/0.6.x
```
  Push with something like git push upstream-rw main-master:master
If this is just a maintenance release from maint/0.6.x or similar, just tag and set the version number to - say - 0.6.2.dev.
Push the tag with git push upstream-rw 0.6.0

Other stuff that needs doing for the release#

Checkout the tagged release, build the html docs and upload them to the github pages website:
```
make upload
```
Announce to the mailing lists. With fear and trembling.
