Contributing to tsflex

First of all, thank you for considering contributing to tsflex.
It's people like you that will help make tsflex a great toolkit! 🤝

As usual, contributions are managed through GitHub Issues and Pull Requests.
We invite you to use GitHub's Issues to report bugs, request features, or ask questions about the project. To ask use-specific questions, please use the Discussions instead.

If you are new to GitHub, you can read more about how to contribute here.

How to develop locally

Note: this guide is tailored to developers using linux

The following steps assume that your console is at the root folder of this repository.

Create a new (poetry) Python environment

It is best practice to use a new Python environment when starting on a new project.

We describe two options;

Advised option: using poetry shell

For dependency management we use poetry (read more below).
Hence, we advise to use poetry shell to create a Python environment for this project.

1. Install poetry: https://python-poetry.org/docs/#installation
   (If necessary add poetry to the PATH)
2. Create & activate a new python environment: poetry shell

After the poetry shell command your python environment is activated.

Alternative option: using python-venv

As alternative option, you can create a Python environment by using python-venv

1. Create a new Python environment: python -m venv venv
2. Activate this environment; source venv/bin/activate

Make sure that this environment is activated when developing (e.g., installing dependencies, running tests).

Installing & building the dependencies

We use poetry as dependency manager for this project.

• The dependencies for installation & development are written in the pyproject.toml file (which is quite similar to a requirements.txt file).
• To ensure that package versions are consistent with everyone who works on this project poetry uses a poetry.lock file (read more here).

To install the requirements

pip install poetry  # install poetry (if you do use the venv option)
poetry install      # install all the dependencies
poetry build        # build the underlying C code

Formatting the code

We use black and ruff to format the code.

To format the code, run the following command (more details in the Makefile):

make format

Checking the linting

We use ruff to check the linting.

To check the linting, run the following command (more details in the Makefile):

make lint

Running the tests (& code coverage)

You can run the tests with the following code (more details in the Makefile):

make test

Documentation

We use pdoc to generate the documentation.

To generate the documentation and view it locally, run the following command:

$ pdoc3 --template-dir docs/pdoc_template/ --http :8181 tsflex/
# you will be able to see the documentation locally on localhost:8181

Bonus points

Bonus points for contributions that include a performance analysis with a benchmark script and profiling output 👀

Details on how we profiled tsflex

Our favored profiling tool is VizTracer which can be used as:

from viztracer import VizTracer

with VizTracer(
    log_gc=False,
    log_async=True,
    output_file=f"<SAVE_PATH>/<save_name>.json",
    max_stack_depth=0,
    # make sure to monitor memory and cpu usage
    plugins=["vizplugins.cpu_usage", "vizplugins.memory_usage"],
):
    # the code that is improved in either memory usage / speed
    ...
