qcompat

qCompat

Soft dependency stubs. These compile against the APIs but don't crash if the mod isn't present.

JEI / REI / EMI

JEIPluginBase.registerRecipeCategory(...);
JEIPluginBase.registerRecipeClickArea(...);

Stubs that delegate to the actually loaded recipe viewer. Only one will be active.

Curios / Trinkets

CuriosCompat.getSlot(player, "ring").ifPresent(stack -> {
    // do something with ring
});

Returns Optional.empty() if neither API is loaded.

ModCompat Scan

ModCompat.scan();

Checks for known mods at startup and logs which APIs are available. Called automatically by QLibs.init().

Adding New Compat

1. Create a stub interface in common/ with a no-op default.
2. Create platform implementations in fabric/ and neoforge/ that check Platform.isModLoaded().
3. Use @ExpectPlatform if the implementation differs between loaders.
