Module content 

.yblock / .yitem content files — a mod’s blocks and items: their properties, 3D model, block states and item form, in one JSON file each, edited in Yog-IDLE’s 3D model editor — and .yrecipe files, one recipe each (crafting, shapeless, smelting), edited in its recipe editor. See Yog-IDLE’s docs/blocks-items.md for the formats.

yog build reads content/**/*.yblock and content/**/*.yitem and

• writes Minecraft’s JSON for them: block models, blockstates, item models, 1.21.4+ item definitions (assets/<ns>/items/), block loot tables, the mineable/<tool> and needs_<level>_tool block tags;
• puts their names and tooltips into the lang files (a @<Set>.<name> text of a .yres file under the key Minecraft looks up, a literal into en_us);
• builds the mod’s textures (.ytexture, see textures);
• generates .yog-build/generated/yog-content.g.rs — Blocks/Items with an id constant and a BlockDef/ItemDef builder per entry and a register function — pulled in by yog_api::content!();, which also registers them (unless an entry says "register": "manual") and every recipe.

Structs

Compiled

Everything yog build makes of a mod’s content files.

Imported

What an import wrote, and what to warn of.

OutputSet

Outputs in order, keyed by path: OutputSet::put replaces a path’s output (moving it to the end) without rescanning the list.

Source

The content’s code: the root file (GENERATED_FILE), which only includes the parts, and the parts — (name, code) each.

Constants

CONTENT_DIR

Where content files live, under the mod root.

GENERATED_FILE

The generated Rust code, under the mod root.

GENERATED_PARTS_DIR

Where the content’s code goes besides the root file, under .yog-build/generated/: one file a part (items.g.rs, register.g.rs, …).

TAGS_FILE

Where the mod’s tags are listed for tools (ns:path → its entries, by kind), as binary Yog Data — the IDE shows a tag’s items from here, as the build makes them.

Functions

compile

Compiles the mod’s content files (see the module docs). Any error fails the whole thing, listing every problem.

import_command

yog import ... (args after import); an error when nothing was written.

merge_outputs

Adds the content’s outputs to outputs (the .yres ones, say): lang entries and tags merged into what’s there (or into the mod’s own files), the rest appended.

read_tags

TAGS_FILE of the mod at root, as the build last wrote it; empty without one.

write_source

Writes compiled.source to GENERATED_FILE (only when it changed); deletes it when the mod has no content files.

Type Aliases

TagLists

The mod’s tags as TAGS_FILE lists them: kind → tag → its entries.
