Contributing

Code in this repository will be formatted with Snakefmt (https://github.com/snakemake/snakefmt).

These practices are subject to change based on the decisions of the team.

  • Structure the files according to the snakemake documentation (https://snakemake.readthedocs.io/en/stable/snakefiles/deployment.html)

  • Follow the Best Practices guidelines in the snakemake documentation (https://snakemake.readthedocs.io/en/stable/snakefiles/best_practices.html)

  • Paths in input and output in rules are relative to the current working directory so that the user can specify a directory to snakemake with

  • Use clear and explicit variable names. (e.g. wildcards is better than merely w)

  • Reference params by keyword even if only one parameter is used in a rule (i.e. {params.taxon} instead of merely {params}).

  • For Python scripts, do not use the snakemake local variable but pass information to the script via a commandline interface using typer and call the script with a shell command (e.g. shell("python SCRIPT_DIR/<script name>.py ...").

  • Place the output of a rule above the input because snakemake goes from output to input when creating the DAG.

Testing

  • Tests must be added for any new rules before merging to the master branch.

  • All tests must be passing before merging with the master branch.

  • Tests should be placed in the tests directory of the root of the repository (NB. not in .tests which is the default snakemake testing directory)

  • Tests can be autogenerated using snakemake -c1 --directory test-data/ --conda-frontend conda --use-conda --generate-unit-tests $(pwd)/tests/unit.

  • Tests are automatically included in the CI/CD pipeline using Github actions.

  • More info on testing with https://snakemake.readthedocs.io/en/stable/snakefiles/testing.html).

Git Commits

We use the git3moji standard for expressive git commit messages. Use one of the following five short emojis at the start of your of your git commit messages:

  • :zap: ⚡️ – Features and primary concerns

  • :bug: 🐛 – Bugs and fixes

  • :tv: 📺 – CI, tooling, and configuration

  • :cop: 👮 – Tests and linting

  • :abc: 🔤 – Documentation

As far as possible, please keep your git commits granular and focussed on one thing at a time. Please cite an the number of a Github issue if it relates to your commit.

Documentation

  • Docstrings for Python functions should use the Google docstring convention (https://google.github.io/styleguide/pyguide.html#38-comments-and-docstrings)

  • Add docstrings should be added to each rule (conventions are still to be decided).

  • Citations for dependencies or research used in any rule should be added in bibtex format to docs/references.bib.

  • Documentation generated using sphinx and automatically deployed as part of the CI/CD pipeline.

  • Should each module in the workflow should have its own page in the documentation?

  • Docs should be written in reStructuredText.

  • Each submodule corresponds to a page in the documentation and added to the table of contents tree (i.e. toctree) in the index.rst file.

Files need to start with a heading for the section. The convention used here is to use the equals sign above and below the heading:

===============
Section Heading
===============

Subsections also use an equals sign but just below the heading:

Subsection Heading
==================

Subsubsections have a single dash below the heading:

Subsubsection Heading
---------------------

Try not to have any other sections within this but if it is necessary, use tildas below the heading:
