Class ModDiscoverer

java.lang.Object

zone.rong.mixinbooter.service.ModDiscoverer

public final class ModDiscoverer
extends java.lang.Object

Discovers all mods present in the game directory at coremod init time independently of Loader which is not available early. Builds a bidirectional mod-id and file mapping used for dependency checking.

Method Summary

Modifier and Type	Method and Description
static void	applyForceLoadAsMod() Honors the ForceLoadAsMod manifest key for every jar collected during discover().
static void	discover() Gathers the same candidate set FML resolves in CoreModManager.discoverCoreMods(java.io.File, net.minecraft.launchwrapper.LaunchClassLoader) (the flat mods/ and mods/<version> directories, command-line --mods, and contained dependencies extracted into memory_repo or the libraries directory) and supplements it with classpath entries already on the LaunchClassLoader for the dev environment.
static void	flushRescuedTweakClasses()
static java.lang.String	getModFromSource(java.io.File source) Returns the id of the mod owning the given jar.
static java.util.Set<java.lang.String>	getModsFromSource(java.io.File source) Returns the ids of the mod(s) owning the given jar, resolved during discover() from its mcmod.info or, when that declares none, its @Mod annotation.
static java.util.Set<java.io.File>	getModSources(java.lang.String modId) Returns the jars that declare the given mod id.
static java.util.Set<java.lang.String>	getPresentMods() Returns the ids of every mod discovered across all scanned jars.
static boolean	isModPresent(java.lang.String modId) Returns whether any discovered jar declares the given mod id.
static void	rescueDroppedCoremods() Loads the FMLCorePlugin of every jar that also declares a TweakClass, which Forge's CoreModManager.discoverCoreMods(java.io.File, net.minecraft.launchwrapper.LaunchClassLoader) skips.

Method Detail

isModPresent

public static boolean isModPresent(java.lang.String modId)

Returns whether any discovered jar declares the given mod id.

Parameters:

modId - the mod id to test

Returns:

true if at least one scanned jar declares the id

getPresentMods

public static java.util.Set<java.lang.String> getPresentMods()

Returns the ids of every mod discovered across all scanned jars.

Returns:

an unmodifiable view of all present mod ids

getModSources

public static java.util.Set<java.io.File> getModSources(java.lang.String modId)

Returns the jars that declare the given mod id. A single mod id may be shipped by more than one jar (e.g. duplicate installs), hence a set.

Parameters:

modId - the mod id to resolve

Returns:

the jars declaring that mod id (empty if none)

getModFromSource

public static java.lang.String getModFromSource(java.io.File source)

Returns the id of the mod owning the given jar. Use getModsFromSource(File) instead if you need every declared id.

Parameters:

source - the jar to resolve

Returns:

the owning mod's id (first declared via mcmod.info, else its @Mod annotation), or null if the jar declares no mod

getModsFromSource

public static java.util.Set<java.lang.String> getModsFromSource(java.io.File source)

Returns the ids of the mod(s) owning the given jar, resolved during discover() from its mcmod.info or, when that declares none, its @Mod annotation. A jar may declare more than one mod (via mcmod.info's modList), hence the set.

Parameters:

source - the jar to inspect

Returns:

the mod ids the jar declares (empty if none)

applyForceLoadAsMod

public static void applyForceLoadAsMod()

Honors the ForceLoadAsMod manifest key for every jar collected during discover(). Replicating the only behavior the removed MixinPlatformAgentFMLLegacy still provided which was un-ignoring jars so Forge would load it as mods. Forge unconditionally adds cascading-tweaker jars to its ignored list and never reaches its own FMLCorePluginContainsFMLMod handling for them. Without this functionality those jars would silently fail to load as mods. Must run after CoreModManager.discoverCoreMods(java.io.File, net.minecraft.launchwrapper.LaunchClassLoader) has fully populated the ignored list, i.e. from injectData and not from the plugin constructor.

rescueDroppedCoremods

public static void rescueDroppedCoremods()

Loads the FMLCorePlugin of every jar that also declares a TweakClass, which Forge's CoreModManager.discoverCoreMods(java.io.File, net.minecraft.launchwrapper.LaunchClassLoader) skips. The removed MixinPlatformAgentFMLLegacy re-injected these via CoreModManager.loadCoreMod and this replicates that. This must run from CoremodsRescuer's constructor while LaunchWrapper is iterating TweakClasses, because rescued coremods such as Sledgehammer may add directly to Tweaks. Any TweakClasses added during rescue are captured and replayed later to avoid corrupting LaunchWrapper's active TweakClasses iterator.

flushRescuedTweakClasses

public static void flushRescuedTweakClasses()

discover

public static void discover()

Gathers the same candidate set FML resolves in CoreModManager.discoverCoreMods(java.io.File, net.minecraft.launchwrapper.LaunchClassLoader) (the flat mods/ and mods/<version> directories, command-line --mods, and contained dependencies extracted into memory_repo or the libraries directory) and supplements it with classpath entries already on the LaunchClassLoader for the dev environment. Must be called once before FML's own mod discovery runs.
