Documentation bug 1 - comment at bottom of the InvTweaksRules

The comment suggests you can create a rule such as D9 12345-13 which appears to be a deprecated format. Not working for me at least (tested using red wool's 0035-14 or 35-14 as well as actual mod item 4945-1).

Documentation bug 2 - first faq item

Moved to appropriate venue.

Correct usage

Referencing items with metadata only seems to be only possible through invTweaksTree. There, examples like <redWool id="wool" damage="14"/> show correct usage for differentiating items by metadata.

Suggestion

It'd be nicer if this mod was more in line with current ways of referring to the metadata on an item. Most¹ mods now refer to red wool as minecraft:wool:14, but this format doesn't work in either file.

Searching the documentation for 'metadata' produced no hits. It took ctrl-f'ing the tree file for colored wool - a lucky guess that you'd supported them already - to figure out the syntax. Only then did I discover that I should've searched the documentation for the outdated² term 'damage value'. At the very least, toss the word 'metadata' in there for better find-ability, please.

Most problematic, however, was that the documentation I did find was incorrect, leading me to try those formats (appending -14 etc).

Footnotes 🤓

1: argumentum ad populum fallacy, but standardization is helpful
2: I have not provided (nor attempted to find) proof that this is no longer the preferred term.

The documentation source is available at Inventory-Tweaks/Docs

There's reasons behind various things:

• With the string IDs I can't very reliably tell if one is a reference to the item ID or to a tree key. (It looks like I just straight replaced the old numbers when that change was made and didn't bother looking too much, and I don't think I've ever touched the default rules file)
• The tree file supports more variation than just damage values, so it is helpful to separate them since they're conceptually different anyway (It's worth noting, in particular, than vanilla's /give command has them as separate arguments)

I've moved doc bug 2 there as a more appropriate venue.

Thanks for the explanation about the format.

Bug 1 still belongs in this repo since it's at line 32 of defaultconfig.
