Code of Conduct

Anyone is welcome to contribute to Popper! To get started, take a look at our contributing guidelines, then dive in with our list of good first issues and open projects.

Popper adheres to the code of conduct posted in this repository. By participating or contributing to Popper, you’re expected to uphold this code. If you encounter unacceptable behavior, please immediately email us.

Install from source

To install Popper in “development mode”, we suggest the following approach:

cd $HOME/

# create virtualenv
python -m virtualenv $HOME/virtualenvs/popper

# load virtualenv
source $HOME/virtualenvs/popper/bin/activate

# clone popper
git clone
cd popper

# install popper from source
pip install -e cli

The -e flag passed to pip tells it to install the package from the source folder, and if you modify the logic in the popper source code you will see the effects when you invoke the popper command. So with the above approach you have both (1) popper installed in your machine and (2) an environment where you can modify popper and test the results of such modifications.

NOTE: The virtual environment created above needs to be reloaded every time you open a new terminal window (source commmand), otherwise the popper command will not be found by your shell.

Contributing CLI features

To contribute new CLI features:

  1. Add a new issue describing the feature.
  2. Fork the official repo and implement the issue on a new branch.
  3. Add tests for the new feature. We test the popper CLI command using Popper itself. The Popper pipeline for testing the popper command is available here.
  4. Open a pull request against the master branch.

Contributing example pipelines

We invite anyone to implement and document Github Action workflows. To add an example, you can fork an open a PR on the repository.
