I'm playing with a custom modpack where I only touch things when they're blatantly incompatible with one another.

I want to use the compact crafting mechanic for the compact machines, but not having default crafting recipes makes that impossible.
Thanks

Hello, you can modify the recipes with datapacks or KubeJS or CraftTweaker.
The wiki can also help you : https://github.com/CompactMods/CompactCrafting/wiki
You can look in the 'src' folder I think robotgryphon has left some tests or examples.
And there is a discord I think someone can help you.

Otherwise there is another repo with recipes : https://github.com/CompactMods/compact-recipes

Oh, I didn't know that other repo existed! Downloading.
Might be good to mention it on the Forge page.

Yes, I know I could use datpacks and the like. But I prefer to spend my time playing inside my world than writing scripts

As already mentioned, CC is meant to be a hands-off mod that a pack maker should explicitly build support for, given that it's a mod whose only goal is to add the new crafting mechanic - nothing else. Given global datapack mods and things like KubeJS, I plan to continue being opt-in on CC/CM4 integration.

If you want to discuss over Discord, there's a link on the repo main README that'll get you there. For now, closing this.
