Acknowledgements

arc is in large part a combination of all the parts I like in other command handlers, with my own spin on it. The following projects have inspired me and aided me greatly in the design of this library:

• hikari-lightbulb - The library initially started as a reimagination of lightbulb, it inherits a similar project structure and terminology.
• Tanjun - For the idea of using typing.Annotated and dependency injection in a command handler. arc also uses the same dependency injection library, Alluka, under the hood.
• hikari-crescent The design of hooks is largely inspired by crescent.
• FastAPI - Some design ideas and most of the documentation configuration derives from FastAPI.
• The arc logo was made by @PythonTryHard.
