Template for Python packages based on Conda.

This package is developed to ease development of ECMWF packages, but it is intended to be more generic.

Alpha stage:

• pre-commit hooks
  • various linters
  • ruff
• version with setuptools-scm-git
• copyright + Apache v2.0 license
• GitHub Actions
  • unit-tests (py3.11)
  • pre-commit
  • integration-tests
  • build documentation
  • static type check
  • build package & publish on PyPI
• Makefile
• gitignore
• make Docker image
• auto template update via cruft
• add documentation skeleton (with sphinx / myst)

Planned:

• keep environment files up-to-date

For best experience create a new conda environment (e.g. DEVELOP) with Python 3.11, cruft and make, then create the package:

conda create -n DEVELOP -c conda-forge python=3.11 cruft make
conda activate DEVELOP
cruft create https://github.com/ecmwf-projects/cookiecutter-conda-package

answer the configuration questions or accept the defaults when in doubt.

Create the git repo and add the pre-commit git hooks:

git init
git add .
git commit -m "Initial commit of the package boilerplate"

Attach an empty remote repository and push the skeleton package:

git branch -M main
git remote add origin [email protected]:ORGANISATION/PROJECT_NAME.git
git push --set-upstream origin main

To setup the package and its dependecies run:

make conda-env-update
conda activate DEVELOP
pre-commit install
pip install -e . --no-deps

Finally to run pre-commit, pytest, and mypy on the newly created package run:

make

To update the boilerplate to the latest template execute:

make template-update
