Title

Discord Support me on Patreon CurseForge Modrinth

Deimos is a data generation and configuration Minecraft library. With it, you can generate config files and display them in-game natively on Forge and Neoforge or with the help of Mod Menu on Fabric. Deimos allows you to create new recipes when the game starts, which makes them configurable. This also means you don't have to use JSON files, and changing Minecraft versions becomes significantly easier and less painful.

The configuration part of this library is based on MidnightLib by Motschen.

I made this mod to simplify my mods' development and allow me to use just one config library across all mod loaders and Minecraft versions. So if you want to see some examples of how to use this library in the wild you can check out the mods I made.

For developers

Below are the instructions for setting up and using Deimos. For more details about this library, be sure to check out its GitHub page.

Setup

You can either use my IntelliJ templates which generate a new MultiLoader project with Deimos preconfigured, or follow these instructions to set it up manually:

In build.gradle

repositories {
    maven {
        url = "https://api.modrinth.com/maven"
    }
}
Forge and Neoforge:
dependencies {
    implementation "maven.modrinth:deimos:${project.deimos_version}"
}
Fabric:
dependencies {
    modImplementation "maven.modrinth:deimos:${project.deimos_version}"
    //if you want to use modmenu
    modCompileOnly "com.terraformersmc:modmenu:${project.modmenu_version}"
}

if you want to use the mod menu functionality you need to add a new repository:

repositories {
    maven {
        name = "Terraformers"
        url = "https://maven.terraformersmc.com/"
    }
}

You can find the specific Deimos version you need on Modrinth

How to use it

Creating configs

You can add configs in a class that extends DeimosConfig:

public class TestConfig extends DeimosConfig {
    @Entry public static int test_int = 6;
    @Entry public static List<String> test_string_list = Lists.newArrayList(
            "minecraft:acacia_planks", "minecraft:andesite");
}

And then in your initialize method you need to call DeimosConfig.init like this:

DeimosConfig.init(MOD_ID, TestConfig.class);

Adding new recipes

To add new recipes you call methods from DeimosRecipeGenerator in your initialize method. You can add shapeless crafting, shaped crafting, smelting, smoking, blasting, campfire and stone cutting recipes. Here are some examples:

DeimosRecipeGenerator.createSmeltingJson(TestConfig.test_string_list.get(0), TestConfig.test_string_list.get(1), TestConfig.test_int, 0.5F);
DeimosRecipeGenerator.createShapedRecipeJson( Lists.newArrayList('#'), Lists.newArrayList(ResourceLocation.parse("sand")), Lists.newArrayList("item"), Lists.newArrayList( "# ", " #" ), ResourceLocation.parse("stone"), 1);

Notice that you can use values from your config file. If the player changes them and restarts the game, the recipes will also change. This even works with modded items.
