A collection of utility classes and functions designed to expand Hikari.


You can install yuyo from PyPI using the following command.

python -m pip install -U hikari-yuyo

The following feature flags ensure feature-specific optional dependencies are also installed:

  • hikari-yuyo[asgi] ensures the dependencies required to run the Asgi RESTBot adapter.
  • hikari-yuyo[sake] can be used to ensure the installed Sake version is compatible with Yuyo's functionality which uses Sake. You should still have a Sake version pinned in your own requirements as this just provides an accepted range for the dependency.
  • hikari-yuyo[tanjun] can be used to ensure the installed Tanjun version is compatible with Yuyo's Tanjun support (i.e. the from_tanjun) class methods.

Quick Usage.#
