Forgiving Tags

If a data pack or a mod lists a tag entry that does not exist, vanilla Minecraft throws away the whole tag. Forgiving Tags keeps every entry that does exist and skips only the ones that do not.

What it does

• Keeps every tag entry that exists and drops only the entries that do not.
• Writes one line to the server log for each affected tag, naming the tag and every skipped entry.
• If something was skipped, tells players once in chat: when they join, and after a data reload.
• Changes nothing else. It adds no blocks, items or commands.

A tested case (Minecraft 26.3)

In our tests on Minecraft 26.3, a data pack that adds one entry that does not exist to the vanilla tag minecraft:wool stops a vanilla server from starting, because other game data depends on that tag. The server log says: Failed to load datapacks, can't proceed with server load. A NeoForge server without this mod did the same.

With Forgiving Tags the same data pack loads. The server starts, white wool stays in the tag, and the log says:

[Forgiving Tags] Tag minecraft:wool skipped entries that do not exist: lmftprobe:no_such_wool (from file/lmftwool); its other entries were kept

(lmftprobe:no_such_wool is the name of the missing entry in our test pack.) We also tested an item tag and a block tag from a test data pack: the missing entry was skipped and the other entries were kept.

Settings

The file config/forgivingtags.json is made the first time the game starts with the mod.

To turn the chat warning off without a file, start the game or the server with the Java option -Dforgivingtags.disable_chat_warning=true.

What changed from LMFT

• Runs on Minecraft 26.3 (the original stops at 1.21.11), on Fabric and on NeoForge.
• The hooks into the game are rewritten for 26.3's tag loader.
• The chat warning contains no web address and no click action. It says that some tag entries were skipped and that the server log names every one.
• The "only operators" setting is fixed. The original hid the warning from operators and showed it to everyone else. With onlyOperatorsSeeWarning set to true, we saw an operator get the warning and a player who is not an operator not get it.
• New names for the settings file (config/forgivingtags.json) and the Java switch (-Dforgivingtags.disable_chat_warning=true).
• A different name, its own code layout and its own wording. The idea and the behaviour are otherwise the same.

Install

• Minecraft 26.3 and Java 25.
• Fabric: Fabric Loader 0.19.3 or newer. Fabric API is not needed.
• NeoForge: 26.3.0.57-beta or newer, within 26.3.
• Put the file for your loader in the mods folder of your server. For singleplayer, put it in the mods folder of your own game.
• Players who join do not need the mod. A player without it sees the same chat warning in plain English.

Versions tested

• Dedicated servers on Minecraft 26.3: Fabric Loader 0.19.3 and 0.19.5 (alone, and 0.19.5 with Fabric API 0.162.0+26.3), NeoForge 26.3.0.57-beta and 26.3.0.77.
• Missing entries in an item tag and a block tag were skipped and the other entries kept, with every loader version listed above. The minecraft:wool case above was tested on Fabric Loader 0.19.5, NeoForge 26.3.0.57-beta and NeoForge 26.3.0.77. A data pack with no missing entry gave no skipped-entry log line.
• A data reload (/reload) was tested on Fabric Loader 0.19.5 and NeoForge 26.3.0.57-beta.
• A client with the mod started to the title screen on Fabric Loader 0.19.5 and NeoForge 26.3.0.57-beta.
• Players joined a server with the mod on Fabric Loader 0.19.5 and NeoForge 26.3.0.57-beta, with and without the mod in their own game. The warning came once on join and once after /reload. With onlyOperatorsSeeWarning on, only an operator saw it. With showChatWarning false, nobody saw it. A data pack with no missing entry gave no warning.
• A server started with the Java option -Dforgivingtags.disable_chat_warning=true (Fabric Loader 0.19.5 and NeoForge 26.3.0.57-beta): nobody saw the warning, an operator included, and the log lines stayed.
• Not tested: singleplayer worlds, several players online at once, other mods next to it (apart from Fabric API on a Fabric server).
