Is your feature request related to a problem? Please describe.

Some mods like Apotheosis and Dark Utilities add single use books, like Tome of Helmets or Galactic Tome. These are deleted when used. So if someone adds these to their tome and uses them, it would delete the whole thing.

Currently, you can blacklist a whole mod, but there is no way to only allow specific items from a mod.

Describe the solution you'd like
One of:

• blacklist a mod, but whitelist one or more items from it.
• blacklist a set of items from a mod
• blacklist single use items automatically (but I don't think there's an easy way to check for this)

FYI, I updated to 1.2.0 to test the blacklist, and:

• I was not able to add any books, regardless of blacklist status.
• if you place the Eccentric Tome and a book in the crafting grid (tested with Apotheosis Chronicle of Shadows), click on the (blank) output, and then drag the Eccentric Tome back to the inventory without moving the other book, it will delete the tome.
• defineList should be defineListAllowEmpty on the config, otherwise NightConfig parses it incorrectly. See relevant discussion here in the Forge discord: https://discord.com/channels/313125603924639766/867851603468615740/903378854670925905

So if someone adds these to their tome and uses them, it would delete the whole thing

That is a good point. I'll add a warning to the readme and Curse Forge project description.

The simplest solution for me to implement would be blacklisting specific items by their resource locations (ids), similar to how the existing item whitelist works.

I might circle back around later and implement more complex black/white listing like the first solution you described.

@jeremiahwinsley could you provide a list of resource locations (like <mod_id>:<item_id> ) for the Tome of Helmets and Galactic Tome?

I could hunt them down on my own, but neither of those mods are part of my current pack.

Alternatively, you're welcome to open up a pull request and add them yourself. Here's an example of how the pull request might look.

Possibly also quark:ancient_tome but I didn't test that.

Thanks for the list and the heads up! I've marked 1.2.0 as an alpha release until I can do more testing.

I'll try defineListAllowEmpty but it doesn't accept List<String> for its arguments so I'll have to figure out a way around that

Here's a reference from one of my mods if it's helpful:

That definitely helped. This feature has now been implemented in d65b300 and 6ea4c36 and published in version 1.2.1
