Development Tools

• Rich is a library to create styled text to the terminal. We'll use it for styling and formatting text.
• Textual is a part of rich to further aid in TUI design. We'll use it to create widgets and adjust the change the layout of the TUI.
• Flit is a simple way to develop Python packages. It's pretty lightweight but can do a lot. We'll use it to manage dependencies.
• pre-commit will run a few tests before you can commit your code. Don't worry, it will make the changes for you. Worst case, you'll have to type the git add/commit lines twice.

Set up the project

Create and activate a virtual environment

python -m venv .venv --prompt template
source .venv/bin/activate

Upgrade pip and install flit manually

python -m pip install -U pip flit

Install the package using symlinks

Run this command to install the package in your virtual environment. If you add dependencies to pyproject.toml, you'll have to run this command again to install the new dependencies. Make sure to pin the version in pyproject.toml.

flit install -s

Install pre-commit

The .pre-commit-config.yaml file is configured to perform the following tasks on each commit:

• Validate yaml files
• Validate toml files
• Ensure a single new line on each file
• Ensure trailing whitespaces are removed
• Format your code with black
• Ensure your python imports are sorted consistently
