Cookiecutter template for authoring (npe2-based) napari plugins by KapoorLabs.
NOTE: This repo is not meant to be cloned/forked directly! Please read "Getting Started" below
Install Cookiecutter and generate a new napari plugin project:
pip install cookiecutter
cookiecutter https://github.com/Kapoorlabs-CAPED/cookiecutter-kapoorlabs-napari-plugin
Cookiecutter prompts you for information regarding your plugin (A new folder will be created in your current working directory):
full_name [Napari Developer]: Varun Kapoor
email [yourname@example.com]: randomaccessiblekapoor@gmail.com
github_username_or_organization [githubuser]: Kapoorlabs-CAPED
# NOTE: for packages whose primary purpose is to be a napari plugin, we
# recommend using the 'napari-' prefix in the package name.
# If your package provides functionality outside of napari, you may
# choose to leave napari out of the name.
plugin_name [vollseg-napari-kickass]: vollseg-napari-kickass

NOTE: This is important not only for version management, but also if you want to
pip install your package locally for testing with pip install -e .
. (because
the version of your package is managed using git tags,
see below)
cd vollseg-napari-kickass
git init
git add .
git commit -m 'initial commit'
-
Create a new github repository
-
Add your newly created github repo as a remote and push:
# here, continuing with the example above... # but replace with your own username and repo name git remote add origin https://github.com/neuronz52/napari-growth-cone-finder.git git push -u origin main
The repository should already be setup to run your tests each time you push an
update (configuration is in .github/workflows/test_and_deploy.yml
). You can
monitor them in the "Actions" tab of your github repository. If you're
following along, go have a look... they should be running right now!
When the tests are done, test coverage will be viewable at
codecov.io (assuming your repository is public):
https://codecov.io/gh/<your-github-username>/<your-package-name>
Your new package is also nearly ready to automatically deploy to PyPI
(whenever you create a tagged release), so that your users can simply pip install
your package. You just need to create an API token to authenticate
with PyPi, and then add it to your github
repository:
- If you don't already have one, create an account at PyPI
- Verify your email address with PyPI, (if you haven't already)
- Generate an API token at PyPi: In your account settings go to the API tokens section and select "Add API token". Make sure to copy it somewhere safe!
- Create a new encrypted secret" in your github repository with the name "TWINE_API_KEY", and paste in your API token.
You are now setup for automatic deployment!
Each time you want to deploy a new version, you just need to create a tagged commit, and push it to your main branch on github. Your package is set up to use setuptools_scm for version management, meaning you don't need to hard-code your version anywhere in your package. It will be inferred from the tag each time you release.
# the tag will be used as the version string for your package
# make it meaningful: https://semver.org/
git tag -a v0.1.0 -m "v0.1.0"
# make sure to use follow-tags so that the tag also gets pushed to github
git push --follow-tags
Note: as of git 2.4.1, you can set
follow-tags
as default withgit config --global push.followTags true
Monitor the "actions" tab on your github repo for progress... and when the "deploy" step is finished, your new version should be visible on pypi:
https://pypi.org/project/<your-package-name>/
and available for pip install with:
# for example
pip install napari-growth-cone-finder
Tests are automatically setup to run on github when you push to your repository.
You can run your tests locally with pytest.
You'll need to make sure that your package is installed in your environment,
along with testing requirements (specified in the setup.cfg extras_require
section):
pip install -e ".[testing]"
pytest
Documentation generation is not included in this template. We recommend following the getting started guides for one of the following documentation generation tools:
This template includes a default yaml configuration for pre-commit.
Among other things, it includes checks for best practices in napari plugins.
You may edit the config at .pre-commit-config.yaml
To use it run:
pip install pre-commit
pre-commit install
You can also have these checks run automatically for you when you push to github by installing pre-commit ci on your repository.
- Installable PyPI package
- tox test suite, testing various python versions and platforms.
README.md
file that contains useful information about your plugin- Continuous integration configuration for github actions that handles testing and deployment of tagged releases
- git-tag-based version management with setuptools_scm
- Optional documentation with either Sphinx or MkDocs
- Choose from several licenses, including BSD-3, MIT, MPL v2.0, Apache v2.0, GNU GPL v3.0, or GNU LGPL v3.0
Please consult the napari plugin docs for more information on how to create a plugin.
