Stable C ABI — re-exported so mods don’t need a direct yog-abi dependency. Passed to yog_mod_register. Call the function pointers here to register handlers, commands, content, and schedulers.

When mods compiled against ABI N load on a runtime with ABI M > N: fields beyond size are not present in the mod’s view — check size before accessing fields added in later minor versions.

size: u32

sizeof(YogApi) at the runtime’s build time.

ctx: *mut c_void

Opaque pointer to runtime handler storage.

server: *const YogServer

register_content: unsafe extern "C" fn(*mut c_void, YogStr, YogStr, *const u8, usize)

Register content of kind (item, block, inventory, recipe, book, dimension, startup_grant) named id: its definition as a Yog Data blob (yog_data::binary, len bytes at data), the shape of yog_registry’s / yog_inventory’s definitions, a recipe in Yog’s format, a book, a dimension. One call for every kind of content — new kinds need no new ABI.

schedule_once: unsafe extern "C" fn(*mut c_void, u64, *mut c_void, unsafe extern "C" fn(*mut c_void, *const YogServer))

schedule_repeating: unsafe extern "C" fn(*mut c_void, u64, *mut c_void, unsafe extern "C" fn(*mut c_void, *const YogServer))

on_screen_close: unsafe extern "C" fn(*mut c_void, *mut c_void, unsafe extern "C" fn(*mut c_void, YogStr) -> bool)

on_world_render: unsafe extern "C" fn(*mut c_void, *mut c_void, unsafe extern "C" fn(*mut c_void, *const YogGfxApi))

Register a handler that fires after world geometry is rendered. gfx.view_proj and gfx.camera_pos are filled; use them to project custom 3D geometry into clip space.

register_ui: unsafe extern "C" fn(*mut c_void, YogStr, YogStr, *mut c_void, unsafe extern "C" fn(*mut c_void, YogStr, YogStr))

Register a UI tree. ui_id is the unique identifier (e.g. “mymod:menu”). layout_json is the serialized layout tree. handler is called when an interactive element is clicked/keyed.

on_ui_render: unsafe extern "C" fn(*mut c_void, YogStr, *mut c_void, unsafe extern "C" fn(*mut c_void, *const YogGfxApi))

Register a render callback that fires during YogUIScreen.render() for a specific UI id — i.e. AFTER the screen darkening, unlike on_hud_render. Reuses YogHudRenderFn (fn(ud, gfx)); gfx.screen_w/h are set. Clicks are forwarded as "click:X:Y" events to the register_ui handler so mods can do their own hit-testing with their stored layout.

register_menu_entry: unsafe extern "C" fn(*mut c_void, YogStr, YogStr)

Register a button/link that the host renders on vanilla screens (TitleScreen on Fabric, ModListScreen on Forge/NeoForge). label is the human-readable button text (e.g. “Yog Mods”). ui_id is the Yog UI to open when clicked (e.g. “example:menu”).

mods_list: unsafe extern "C" fn(*mut c_void) -> YogOwnedStr

All installed mods as TSV, one per line: source \t id \t name \t version \t authors \t description where source is yog (a .yog mod) or platform (a loader mod, e.g. a Fabric/Forge jar). Tabs and newlines inside fields become spaces. Callable at any time after registration (also client-side).

free_str: unsafe extern "C" fn(*mut u8, u32)

Free a YogOwnedStr returned by an api-table call (same allocator as YogServer::free_str).

ui_open: unsafe extern "C" fn(*mut c_void, YogStr, bool, bool)

Open the Yog UI registered as ui_id on the client (schedules onto the render thread). Client-side only; a no-op on dedicated servers. modal blocks game input; pause pauses a singleplayer game.

interop_export: unsafe extern "C" fn(*mut c_void, YogStr, YogStr, *const c_void)

Export a function pointer under symbol for the calling mod (mod_id). Other mods can import it via interop_import.

interop_import: unsafe extern "C" fn(*mut c_void, YogStr, YogStr) -> *const c_void

Import a function pointer exported by mod_id under symbol. Returns null if the symbol is not (yet) registered.

register_chunk_generator: unsafe extern "C" fn(*mut c_void, YogStr, *mut c_void, unsafe extern "C" fn(*mut c_void, *const YogChunkWriterApi))

Register a chunk generator for a previously-declared dimension id. handler is called once per chunk column that needs generating — see YogChunkWriterApi/YogChunkGeneratorFn.

ui_close: unsafe extern "C" fn(*mut c_void, YogStr)

Close the Yog UI screen showing ui_id (empty = whichever Yog UI screen is open). Scheduled onto the render thread, so it’s safe to call from that screen’s own event handler. Client-side only.

ui_consume_event: unsafe extern "C" fn(*mut c_void)

Called from inside a register_ui handler while it handles a key: or char: event: the mod used the key, so the host skips its default handling (Esc closing the screen, Tab focus navigation, …).

translate: unsafe extern "C" fn(*mut c_void, YogStr) -> YogOwnedStr

The text of translation key key (e.g. mymod.screen.title) in the game’s current language, from the loaded lang files — resource packs and .yog mods’ assets/<ns>/lang/*.json (compiled from .yres). YogOwnedStr::NONE when no language defines the key. Format specifiers (%s, %1$s) come back as-is. Free with free_str. Client-side; a dedicated server only knows en_us.

ui_open_flags: unsafe extern "C" fn(*mut c_void, YogStr, u32)

Like ui_open, with ui_flags bits: MODAL, PAUSE, NO_BACKGROUND (no dimmed/blurred world behind the screen). Client-side only.

client_play_sound: unsafe extern "C" fn(*mut c_void, YogStr, f32, f32, bool) -> u32

Play sound event sound_id for the local player only: at the player’s position, or (looping) as a loop that follows the player until client_stop_sound. Returns a handle (0 = failed).

client_stop_sound: unsafe extern "C" fn(*mut c_void, u32)

Stop a sound started by client_play_sound (0 or unknown: no-op).

client_held_item: unsafe extern "C" fn(*mut c_void, bool) -> YogOwnedStr

Item id in the local player’s main hand (off_hand false) or off hand, YogOwnedStr::NONE for air or no player. Free with free_str.

client_set_block_tint: unsafe extern "C" fn(*mut c_void, YogStr, YogBlockPos, i64)

Tints the block at pos in dim on this client (its faces with a tint index), color 0xRRGGBB; -1 clears it.

client_key_down: unsafe extern "C" fn(*mut c_void, i32) -> bool

Whether GLFW key key is held down right now (client window).

on_book_page: unsafe extern "C" fn(*mut c_void, YogStr, *mut c_void, unsafe extern "C" fn(*mut c_void, *const YogGfxApi, *const u8, usize, f32, f32, f32, f32))

Draw the pictures of book pages of type drawn whose drawer is drawer (hexcasting:pattern) — see YogPageDrawFn.

on_item_tooltip: unsafe extern "C" fn(*mut c_void, YogStr, *mut c_void, unsafe extern "C" fn(*mut c_void, YogStr, YogStr, *mut f32, *mut f32) -> bool, unsafe extern "C" fn(*mut c_void, *const YogGfxApi, YogStr, YogStr, f32, f32, f32, f32))

A picture under the tooltip of item item (Hex Casting’s scrolls show their pattern): size says whether a stack gets one and how big, draw draws it — see YogTooltipSizeFn, YogTooltipDrawFn.

is_mod_loaded: unsafe extern "C" fn(*mut c_void, YogStr) -> bool

Whether mod id is loaded — a Yog mod or a Java one (Fabric’s, Forge’s or NeoForge’s mod list).

java_call: unsafe extern "C" fn(*mut c_void, YogStr, YogStr) -> YogOwnedStr

Calls into a Java mod’s API by reflection: expr is a chain from a class — virtuoel.pehkui.api.ScaleTypes.BASE.getScaleData($0).getScale() — $n the n-th of args, a list in Yog Data text (an entity is @entity:<uuid>). The result in Yog Data text, or YogOwnedStr::NONE when the call failed (said in the log). Free with free_str.

on_item_text: unsafe extern "C" fn(*mut c_void, YogStr, *mut c_void, unsafe extern "C" fn(*mut c_void, YogStr, YogStr, *mut c_void, unsafe extern "C" fn(*mut c_void, YogStr)) -> bool)

The name and tooltip lines of stacks of item from its custom data (a written blueprint shows its design) — see YogItemTextFn.

on_machine_craft: unsafe extern "C" fn(*mut c_void, *mut c_void, unsafe extern "C" fn(*mut c_void, *const YogServer, *const YogMachineCraftEvent, u8) -> bool)

A machine making a recipe — see YogMachineCraftEvent.

client_body_track: unsafe extern "C" fn(*mut c_void, YogStr, bool)

Asks the mods about entity uuid’s body each frame (on) or not.

client_body_track_type: unsafe extern "C" fn(*mut c_void, YogStr, bool)

The same for every entity of type entity_type.

on_body: unsafe extern "C" fn(*mut c_void, *mut c_void, unsafe extern "C" fn(*mut c_void, *const u8, usize, *mut c_void, unsafe extern "C" fn(*mut c_void, *const u8, usize)))

The body of a tracked entity, each frame — see YogBodyFn.

on_camera: unsafe extern "C" fn(*mut c_void, *mut c_void, unsafe extern "C" fn(*mut c_void, *const YogCameraFrame, *mut YogCameraOut))

The camera, each frame — see YogCameraFn.

on_travel: unsafe extern "C" fn(*mut c_void, *mut c_void, unsafe extern "C" fn(*mut c_void, *const YogTravelFrame, *mut [f32; 3]) -> bool)

The local player’s travel step, each tick — see YogTravelFn.

client_set_dimensions: unsafe extern "C" fn(*mut c_void, YogStr, f32, f32, f32)
