An annotation-driven and reflection-free command framework.
Important
It has been a good run, but all good things must come to an end. Chimera was one of my first OSS projects & what got me into programming. I haven't touched Minecraft in years and no longer have the resources nor interest in continued maintenance. Thanks for all the fish.

-
Improved performance - Since annotations are processed at compile-time, we can avoid many of the performance pitfalls associated with reflection.
-
Light(er)weight Dependencies - All Typist annotations are discarded after compilation and generated code do not rely on Typist, hence it doesn't need to be bundled with the plugin. The only dependency required is Chimera.
-
Low Learning Curve & Safety - One benefit of compile-time annotation processing is the ability to check annotations at compile-time. This means errors can be caught eariler by the annotation processor and thus easier to learn and safer.
-
Native Brigadier Support - Typist is built on Chimera, hence by extension, built on Brigadier.
-
Better Developer Experience - No need to compile the plugin, fiddle with the jar, boot-up a Spigot server and pray it doesn't instantly hurl an error. Typist has a slightly shorter feedback loop.
