Feature Request

Handle the CraftRecipeRequest in feather/server/src/packet_handlers.rs

Description

This packet is sent when a player clicks a recipe in the crafting book that is craftable (white border). 

Wiki

To implement handle this packet we need to have a list of every Minecraft recipe. We also want this list to be viewable and editable by plugins. As far as i know feather currently does not have any knowledge of recipes. And implementing this feature would require multiple steps.

a) Add recipes to libcraft

In /libcraft we have definitions on minecraft related data. This is probably were we want to add a definition containing all vanilla recipes. (Ask someone on discord to make sure).

minecraft-data is a awesome project that collects minecraft related data. They keep up to date sources for stuff like recipes. You would have to implement a rust macro that converts the json into rust structs.
This is somewhat difficult for beginners, as macros are tricky.

b) Add recipe handling to quill.

For this step i am not a 100% certain on how it should be implemented. But my idea is that we put recipes into the ECS. Every recipe is just a entity with a recipe component. The file quill/common/src/components.rs has defined a couple of components that might be a starting point for anyone interested in implementing this feature. Another solution is that we manage recopies through host-calls.
Host calls are defined in quill/sys. They're FFI functions that plugins can call to do things on the server. Host calls have to be implemented in feather/plugin-host/src/host_calls.rs. To invoke a function on the plugin, you have to export it with #[no_mangle]. See the macro in quill/api/src/lib.rs for an example for how this works.
