Documentation is still a work in progress, and the library should currently be considered unstable.

You can install it using pip, eg. pip install dslash.

Planned Features

• Class-based command groups, like nextcord.ext.commands cogs.

Compatibility with nextcord.ext.commands is not planned.

Development

As well as Python 3.9+, this project requires Poetry for development. Click this link for installation instructions, or:

• *nix (Linux/MacOS)

  curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python -

• Windows Powershell

  (Invoke-WebRequest -Uri https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py -UseBasicParsing).Content | python -

Once you have Poetry installed:

1. Create a virtual environment: poetry shell
2. Install dependencies: poetry install

The following commands are then available:

• poe format - Run auto-formatting and linting.

Prefix these with poetry run if outside of the Poetry shell.
