Icon

Awful, I know. Make a better one if you want to.

Currently it's these 2 things combined:

• https://thenounproject.com/term/crane/1689627/ (bought the rights to use)
• https://material.io/resources/icons/?icon=directions_bus&style=outline (apache 2.0)

Development

This project uses isort and black for file formatting and pyright for type checking. The maximum line length is increased to 99, and the type checking is set to strict.

CI runs the following commands to help maintain high code quality:

$ black --check .
$ isort --check .
$ pyright
$ python -m pytest

If you use VS Code I recommend using the following settings:

{
    "[python]": {
        "editor.codeActionsOnSave": {
            "source.organizeImports": true
        },
        "editor.formatOnSave": true
    },
    "js/ts.implicitProjectConfig.checkJs": true,
    "python.formatting.provider": "black",
    "python.languageServer": "Pylance",
    "python.linting.enabled": false,
}
