Environment setup

Nothing easier! Follow the instructions below.

Note

We STRONGLY recommend using a Linux distribution for Python development (Windows sometimes leads to obscure compatibility errors...)

1. Install Git to version and track our software changes.

   • On Windows, use the official installer: Git-for-Windows.

   • On Linux, simply use your package manager.

   Note

   Git-for-Windows doesn't provide the command make. In following step, use pdm instead.

2. Install Python as programming language for this projet.

   • On Windows, use the official installer: Python Releases for Windows.

   • On Linux, simply use your package manager.

   Note

   You can also use use pyenv.

   # install pyenv
   git clone https://github.com/pyenv/pyenv ~/.pyenv
   
   # setup pyenv (you should also put these three lines in .bashrc or similar)
   export PATH="${HOME}/.pyenv/bin:${PATH}"
   export PYENV_ROOT="${HOME}/.pyenv"
   eval "$(pyenv init -)"
   
   # install Python 3.8
   pyenv install 3.8
   
   # make it available globally
   pyenv global system 3.8
   

3. Fork and clone the repository:

   git clone https://github.com/cognitivefactory/interactive-clustering-gui/
   cd interactive-clustering-gui
   

4. Install the dependencies of the projet with:

   cd interactive-clustering
   make setup # on Linux
   pdm install # on Windows
   

   Note

   If it fails for some reason (especially on Windows), you'll need to install pipx and pdm manually.

   You can install them with:

   python3 -m pip install --user pipx
   pipx install pdm
   

   Now you can try running make setup again, or simply pdm install.

Your project is now ready and dependencies are installed.

Available template tasks

This project uses duty to run tasks. A Makefile is also provided. To run a task, use make TASK on Linux and pdm run duty TASK on Windows.

To show the available template task:

make help # on Linux
pdm run duty --list # on Windows

The Makefile will try to run certain tasks on multiple Python versions. If for some reason you don't want to run the task on multiple Python versions, you can do one of the following:

1. export PYTHON_VERSIONS=: this will run the task with only the current Python version
2. run the task directly with pdm run duty TASK

The Makefile detects if a virtual environment is activated, so make/pdm will work the same with the virtualenv activated or not.

Development journey

As usual:

1. create a new branch: git checkout -b feature-or-bugfix-name
2. edit the code and/or the documentation

If you updated the documentation or the project dependencies:

1. run make docs-regen
2. run make docs-serve, go to http://localhost:8000 and check that everything looks good

Before committing:

1. run make format to auto-format the code
2. run make check to check everything (fix any warning)
3. run make test to run the tests (fix any issue)
4. follow our commit message convention

If you are unsure about how to fix or ignore a warning, just let the continuous integration fail, and we will help you during review.

Don't bother updating the changelog, we will take care of this.

Commit message convention

Commits messages must follow the Angular style:

<type>[(scope)]: Subject

[Body]

Scope and body are optional. Type can be:

• build: About packaging, building wheels, etc.
• chore: About packaging or repo/files management.
• ci: About Continuous Integration.
• docs: About documentation.
• feat: New feature.
• fix: Bug fix.
• perf: About performance.
• refactor: Changes which are not features nor bug fixes.
• style: A change in code style/format.
• tests: About tests.

Subject (and body) must be valid Markdown. If you write a body, please add issues references at the end:

Body.

References: #10, #11.
Fixes #15.

Pull requests guidelines

Link to any related issue in the Pull Request message.

During review, we recommend using fixups:

# SHA is the SHA of the commit you want to fix
git commit --fixup=SHA

Once all the changes are approved, you can squash your commits:

git rebase -i --autosquash master

And force-push:

git push -f

If this seems all too complicated, you can push or force-push each new commit, and we will squash them ourselves if needed, before merging.
