Discord Integration addons are meant to be usable independant of the target minecraft loader. They are made to create custom slash commands or add other discord-side features without depending on any minecraft resources or mods.

1. Add my maven repository

repositories {
    maven { url "https://repo.erdbeerbaerlp.de/repository/maven-public/" }
}

1. Add dependency of DiscordIntegration-Core

dependencies {
    compileOnly 'de.erdbeerbaerlp:dcintegration.common:3.0.7'
    compileOnly group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.17.1'
}

Adding log4j is optional, but required if you want to use it for logging

For your addon to be actually loaded, it needs some metadata in form of a .toml file inside of src/main/resources folder. It has to be named DiscordIntegrationAddon.toml. Full file path would be src/main/resources/DiscordIntegrationAddon.toml

Here is an documented example of such an toml file:

# Name of the addon
name = "Example Addon"

# Version of the addon
version = "1.0.0"
# Path to the main class of the addon
# Example: "com.example.exampleaddon.ExampleAddon"
#
# If this parameter is missing, your addon will not load
classPath = "com.example.exampleaddon.ExampleAddon"

# Author of the Addon (optional)
author = "ErdbeerbaerLP"

# Description of the Addon (optional)
description = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras efficitur tellus semper, elementum magna ac, tincidunt risus."

# Required parameter to specify if the addon is compatible with this API version
APIVersion = 3

Your addon class needs to implement DiscordIntegrationAddon.

Here a working example of a addon main class

public class ExampleAddon implements DiscordIntegrationAddon {

    @Override
    public void load(DiscordIntegration dc) {
        DiscordIntegration.LOGGER.info("Example Addon loaded");
    }

    @Override
    public void reload() {
        DiscordIntegration.LOGGER.info("Example Addon reloaded");
    }

    @Override
    public void unload(DiscordIntegration dc) {
        DiscordIntegration.LOGGER.info("Example Addon unloaded");
    }

}

To use a configuration file for your addon, you will have to register it in your load method. It is also recommended to reload that config in the reload method.

Here a working example of an addon class with config loading implemented

public class ExampleAddon implements DiscordIntegrationAddon {
    private ExampleConfig cfg;

    @Override
    public void load(DiscordIntegration dc) {
        DiscordIntegration.LOGGER.info("Example Addon loaded");
        cfg = AddonConfigRegistry.loadConfig(ExampleConfig.class, this);
        DiscordIntegration.LOGGER.info(cfg.exampleMessage);
    }

    @Override
    public void reload() {
        DiscordIntegration.LOGGER.info("Example Addon reloaded");
        cfg = AddonConfigRegistry.loadConfig(cfg,this);
    }

    @Override
    public void unload(Discord dc) {
        DiscordIntegration.LOGGER.info("Example Addon unloaded");
    }
}

… and the config class file:

public class ExampleConfig {
    @TomlComment({"Config entry comment", "You can also have multiple lines here"})
    public String exampleMessage = "Hello World";
}
