Marrow
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Marrow
Minecraft mod that bundles Arrow for ease-of-use and installation.
Usage
Simply add it as a dependency to your Gradle project like so:
Groovyrepositories {
mavenCentral()
maven("https://maven.is-immensely.gay/nightly")
}
dependencies {
def variantAttribute = Attribute.of("earth.terrarium.cloche.modLoader", String::class)
modImplementation("xyz.naomieow:marrow:2.1.2") {
attributes {
// "fabric" for fabric
// "forge" for forge
// "neoforge" for neoforge
attribute(variantAttribute, "fabric")
}
}
}
Kotlin DSLrepositories {
mavenCentral()
maven("https://maven.is-immensely.gay/nightly")
}
dependencies {
val variantAttribute = Attribute.of("earth.terrarium.cloche.modLoader", String::class.java)
modImplementation("xyz.naomieow:marrow:2.1.2") {
attributes {
// "fabric" for fabric
// "forge" for forge
// "neoforge" for neoforge
attribute(variantAttribute, "fabric")
}
}
}
Kotlin DSL (Cloche)repositories {
mavenCentral()
maven("https://maven.is-immensely.gay/nightly")
}
common {
dependencies {
modImplementation("xyz.naomieow:marrow:2.1.2")
}
}
And then you should have access to Arrow in your project:
val example: Either<String, Int> = Either.Left("Hello world!")
Versioning
Marrow tracks the upstream version of Arrow, which is why the initial release is tagged
as version 2.1.2. If you ever find Marrow to be outdated, please create an issue or
