kamuidrome 0.8.0

Modern Minecraft modpack builder

Kamuidrome is a Minecraft modpack creation helper that integrates directly with Prism Launcher. Kamuidrome is currently geared entirely towards modpack developers, not modpack users. Modpack users should use the exported mrpack packs instead.

Kamuidrome comes with first-class support for Sinytra Connector, meaning you can manage Fabric mods in a Forge workspace without issues.

Installation

Kamuidrome is available on PyPI, and can be installed with pipx:

$ pipx install kamuidrome

Getting Started

A new, empty modpack can be created using the kamuidrome init subcommand. This will interactively guide you through setting up your pack.toml and generate a skeleton file structure for you.

$ kamuidrome init --git
Pack name: My Awesome Modpack
Minecraft version: 1.20.1
Pack version (0.1.0): 0.1.0
Modloader [legacyforge/neoforge/fabric/quilt]: fabric
Modloader version (leave empty for auto): 0.15.3

Adding Mods

Modrinth mods can be added to your modpack in one of three ways:

• Using kamuidrome add [-s/--search] to add a mod via a search query. This will add mods either based on a direct name match (most commonly) or allow you to select the mod you mean.

• Using kamuidrome add [-p/--project-id] to add the latest version of a specific project, based on its Modrinth project ID.

• Using kamuidrome add [-V/--version-id] to add a specific version of a specific project.

When adding a mod, dependencies will be automatically resolved and downloaded if the author has provided the appropriate metadata on Modrinth.

$ kamuidrome add -s "Big Globe"
successful match: Big Globe / xsng1aJf
selected version 3.12.0 for Big Globe
selected version 0.91.0+1.20.1 for [1.20.1] Fabric API 0.91.0+1.20.1

Mod Caching

Mods are automatically cached in your $XDG_CACHE_HOME directory, meaning that specific mod versions will only ever be downloaded once.

Adding Local Mods

Any mods in the mods/ directory are considered “local mods”, and will be ignored by kamuidrome outside of deployments and exporting. You can use this for mods that aren’t available on Modrinth (provided you obey copyright requirements).

Sinytra Connector

When using a legacyforge or neoforge pack with sinytra_compat enabled, all mods with a fabric category will be valid for installation. In the case of mods that have both a Fabric and a Forge version available, the Forge version will always be selected, even if the Fabric version is newer.

Fabric API dependencies will automatically be rewritten to Forgified Fabric API when adding mods with the command line.

Installing Indexed Mods

Whilst kamuidrome add adds mods to the index, other developers need to be able to install all of the mods when checking out the repository. The kamuidrome download command will download all mods in the modpack index and store them in the mod cache.

$ kamuidrome download                                                                                                                                                                                                                ↵ 2

Listing Indexed Mods

The kamuidrone list command can be used to list all mods currently installed in the index.

Updating Mods

Mods can be automatically updated with the kamuidrome update command. This will fetch version information for all mods in the mod index and update all non-pinned mods to their latest version.

$ kamuidrome update
selected version 3.12.0 for Big Globe
selected version 0.91.0+1.20.1 for [1.20.1] Fabric API 0.91.0+1.20.1
selected version 0.91.0+1.20.1 for Fabric API

Pinning Mods

If a mod you have in your index can’t be updated (possibly due to incompatibility or bugs) you can pin the version using the kamuidrome pin command or by editing the pinned field in the index manually.

$ kamuidrome pin "Big Globe"
pinned mod Big Globe to version 3.12.0

Updates for pinned mods will still be downloaded, but the metadata in the mod index will not be changed.

Prism Integration

Kamuidrome has Prism Launcher integration as a first class feature via the power of symbolic links. You can automatically deploy a modpack to an instance with the kamuidrome deploy command, which will symlink data from your download mod cache and local pack directory.

This is a more flexible approach than ones used by other pack builders (such as Packwiz); for example, you can edit configurations in-game and have the changes saved to your config directory in your pack without needing to synchronise.

$ kamuidrome deploy -i "test pack"
cleaning up symlinks from index...
linked included dir /home/lura/.local/share/PrismLauncher/instances/test pack/.minecraft/config
linked managed mod /home/lura/.local/share/PrismLauncher/instances/test pack/.minecraft/mods/Big Globe-3.12.0-MC1.20.1.jar
linked managed mod /home/lura/.local/share/PrismLauncher/instances/test pack/.minecraft/mods/fabric-api-0.91.0+1.20.1.jar

Please note that this will delete any data in the instance’s config directory, or any other synchronised directories (outside of jars in the mods/ directory) before creating the symbolic links.

You can store an instance name in the localpack.toml file (this should be added to your gitignore) so that you don’t need to type the instance name when running the deploy command.

# example ``localpack.toml`` file
instance_name = "test pack"

Adding Extra Directories

Extra directories for both deployment and export can be added with the include_directories key in your pack.toml:

include_directories = [
   "kubejs",
]

These directories will be symlinked to your instance folder and included in the generated mrpack.
