# Contributing guide | ||
|
||
Scanpy provides extensive [developer documentation][scanpy developer guide], most of which applies to this repo, too. | ||
This document will not reproduce the entire content from there. Instead, it aims at summarizing the most important | ||
information to get you started on contributing. | ||
|
||
We assume that you are already familiar with git and with making pull requests on GitHub. If not, please refer | ||
to the [scanpy developer guide][]. | ||
|
||
## Installing dev dependencies | ||
|
||
In addition to the packages needed to _use_ this package, you need additional python packages to _run tests_ and _build | ||
the documentation_. It's easy to install them using `pip`: | ||
|
||
```bash | ||
cd cookiecutter-scverse-instance | ||
pip install -e ".[dev,test,doc]" | ||
``` | ||
|
||
## Code-style | ||
|
||
This template uses [pre-commit][] to enforce consistent code-styles. On every commit, pre-commit checks will either | ||
automatically fix issues with the code, or raise an error message. See [pre-commit checks](template_usage.md#pre-commit-checks) for | ||
a full list of checks enabled for this repository. | ||
|
||
To enable pre-commit locally, simply run | ||
|
||
```bash | ||
pre-commit install | ||
``` | ||
|
||
in the root of the repository. Pre-commit will automatically download all dependencies when it is run for the first time. | ||
|
||
Alternatively, you can rely on the [pre-commit.ci][] service enabled on GitHub. If you didn't run `pre-commit` before | ||
pushing changes to GitHub it will automatically commit fixes to your pull request, or show an error message. | ||
|
||
If pre-commit.ci added a commit on a branch you still have been working on locally, simply use | ||
|
||
```bash | ||
git pull --rebase | ||
``` | ||
|
||
to integrate the changes into yours. | ||
While the [pre-commit.ci][] is useful, we strongly encourage installing and running pre-commit locally first to understand its usage. | ||
|
||
Finally, most editors have an _autoformat on save_ feature. Consider enabling this option for [black][black-editors] | ||
and [prettier][prettier-editors]. | ||
|
||
[black-editors]: https://black.readthedocs.io/en/stable/integrations/editors.html | ||
[prettier-editors]: https://prettier.io/docs/en/editors.html | ||
|
||
## Writing tests | ||
|
||
```{note} | ||
Remember to first install the package with `pip install '-e[dev,test]'` | ||
``` | ||
|
||
This package uses the [pytest][] for automated testing. Please [write tests][scanpy-test-docs] for every function added | ||
to the package. | ||
|
||
Most IDEs integrate with pytest and provide a GUI to run tests. Alternatively, you can run all tests from the | ||
command line by executing | ||
|
||
```bash | ||
pytest | ||
``` | ||
|
||
in the root of the repository. Continuous integration will automatically run the tests on all pull requests. | ||
|
||

|
||
## Publishing a release | ||
|
||
### Updating the version number | ||
|
||
Before making a release, you need to update the version number. Please adhere to [Semantic Versioning][semver], in brief | ||
|
||
> Given a version number MAJOR.MINOR.PATCH, increment the: | ||
> | ||
> 1. MAJOR version when you make incompatible API changes, | ||
> 2. MINOR version when you add functionality in a backwards compatible manner, and | ||
> 3. PATCH version when you make backwards compatible bug fixes. | ||
> | ||
> Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format. | ||
We use [bump2version][] to automatically update the version number in all places and automatically create a git tag. | ||
Run one of the following commands in the root of the repository | ||
|
||
```bash | ||
bump2version patch | ||
bump2version minor | ||
bump2version major | ||
``` | ||
|
||
Once you are done, run | ||
|
||
``` | ||
git push --tags | ||
``` | ||
|
||
to publish the created tag on GitHub. | ||
|
||

|
||
### Building and publishing the package on PyPI | ||
|
||
Python packages are not distributed as source code, but as _distributions_. The most common distribution format is the so-called _wheel_. To build a _wheel_, run | ||
|
||
```bash | ||
python -m build | ||
``` | ||
|
||
This command creates a _source archive_ and a _wheel_, which are required for publishing your package to [PyPI][]. These files are created directly in the root of the repository. | ||
|
||
Before uploading them to [PyPI][] you can check that your _distribution_ is valid by running: | ||
|
||
```bash | ||
twine check dist/* | ||
``` | ||
|
||
and finally publishing it with: | ||
|
||
```bash | ||
twine upload dist/* | ||
``` | ||
|
||
Provide your username and password when requested and then go check out your package on [PyPI][]! | ||
|
||
For more information, follow the [Python packaging tutorial][]. | ||
|
||
It is possible to automate this with GitHub actions, see also [this feature request][pypi-feature-request] | ||
in the cookiecutter-scverse template. | ||

||

|
||
## Writing documentation | ||
|
||
Please write documentation for new or changed features and use-cases. This project uses [sphinx][] with the following features: | ||
|
||
- the [myst][] extension allows to write documentation in markdown/Markedly Structured Text | ||
- [Numpy-style docstrings][numpydoc] (through the [napoloen][numpydoc-napoleon] extension). | ||
- Jupyter notebooks as tutorials through [myst-nb][] (See [Tutorials with myst-nb](#tutorials-with-myst-nb-and-jupyter-notebooks)) | ||
- [Sphinx autodoc typehints][], to automatically reference annotated input and output types | ||
|
||
See the [scanpy developer docs](https://scanpy.readthedocs.io/en/latest/dev/documentation.html) for more information | ||
on how to write documentation. | ||
|
||
### Tutorials with myst-nb and jupyter notebooks | ||
|
||
The documentation is set-up to render jupyter notebooks stored in the `docs/notebooks` directory using [myst-nb][]. | ||
Currently, only notebooks in `.ipynb` format are supported that will be included with both their input and output cells. | ||
It is your reponsibility to update and re-run the notebook whenever necessary. | ||
|
||
If you are interested in automatically running notebooks as part of the continuous integration, please check | ||
out [this feature request](https://github.com/scverse/cookiecutter-scverse/issues/40) in the `cookiecutter-scverse` | ||
repository. | ||
|
||
#### Hints | ||
|
||
- If you refer to objects from other packages, please add an entry to `intersphinx_mapping` in `docs/conf.py`. Only | ||
if you do so can sphinx automatically create a link to the external documentation. | ||
- If building the documentation fails because of a missing link that is outside your control, you can add an entry to | ||
the `nitpick_ignore` list in `docs/conf.py` | ||
|
||
#### Building the docs locally | ||
|
||
```bash | ||
cd docs | ||
make html | ||
open _build/html/index.html | ||
``` | ||
|
