Recipes (Horizon native mod)

Horizon's official recipe viewer: every item beside your inventory, with a search box (#tag searches a tag). R over an item shows its recipes, one tab per station; U shows its uses. The + under a crafting recipe you know fills the crafting grid, as the recipe book does. In creative mode, turn on "Click gives items" (Options > Mods > Recipes > Settings): a click on an item in the panel gives you one, a right click a stack. Change R and U on the mod's page in Options > Mods.

It is a horizon-mixins bundle (mixins/recipes/) that the Horizon launcher builds into the game. It keeps the settings of earlier versions: the same file (horizon-mods/.horizon-mod-data/recipes/give) and the same keys (key.recipes.recipe, key.recipes.uses in horizon-mods.txt).

Install

In the Horizon launcher: Mods → Recipes → Install, then Build on the same page (once built, switch it on or off in the game under Options → Mods). The launcher downloads its own Rust and builds the game with your native mods; see Horizon's native mods.

Made on the hook points

The bundle hooks only Horizon's native hook points (crates/horizon-client/src/game/native_hooks.rs), which keep their names and signatures across releases. It needs the item panel and the recipe tables, so compatibility.json names version 2 ("hooks": 2): the launcher builds Recipes on any Horizon with that version or a later one, the player's own game by default, together with any other mod. horizon_revision is only the commit it was last tested on.

File	What it is
mixins/recipes/horizon-mixin.toml	The bundle: two modules and the HEAD hooks
mixins/recipes/runtime.rs	The viewer: search, pages per station, history, and its tests; added to the game as game::official_recipes, and this crate's library
mixins/recipes/glue.rs	The viewer's edges in the game (game::official_recipes_glue): the game's tables and panel events in, the panel, give and place out
mixins/recipes/*.rs	One small helper per hook
proof.py (with ../tools/game.py)	The proof: the built game driven with horizon-ctl --offscreen on fresh, temporary data

Build and prove

(cd native/recipes && cargo test)                    # the viewer
python3 native/tools/native.py check recipes         # apply on the tested Horizon and cargo check the game
python3 native/tools/native.py check all             # with the other native mods, as a player's set
python3 native/tools/native.py package recipes       # native/target/recipes-<version>.hnmod for the registry
python3 native/tools/native.py proof recipes --resources /path/to/.local/horizon-client/26.3

The proof needs resources prepared from your own Minecraft 26.3 (horizon-prepare); none are in this repository. It seeds an earlier version's setting ("Click gives items" on) in a temporary game folder, checks that Options > Mods shows the mod, its keys and the setting, then opens the inventory: the panel shows items, a click on one in creative mode gives it, and with the setting turned off the same click opens its recipe page.
