The Meaning of Life, the Universe, and Everything.
In the Minecraft Snapshots for 1.12, Mojang introduced a new recipe format, which allows for the creation of custom recipes, however it's a bit annoying to do, so I made a tool to help you do it much more seamlessly.
I've made a tutorial on how to use this mod, I didn't have my mic when I was making it though so I typed out the tutorial in notepad (just like the good old days) Warning: It's pretty lengthy and very wordy
This program only works with singleplayer currently, if I figure out how to get it working in multiplayer, I will add an updated version.
I made this program over the course of a few days mostly for my own use, but I liked it so much that I decided to release it for others, if you find any bugs you can report them in the comments here or open an issue up on the github page feedback is also more than welcome and if you have suggestions I'd love to hear those as well, but I can't promise I'll implement any of them as this was mostly just a pet project.
