# BetterConfig A very powerful and easy to use command based configuration library for servers and clients. ## Creating a simple configuration To start, create a new class. This will be the class where all your configurations are stored. For this example, we'll call this class `Configs`. Make sure that this class is `public`! Next, create a field for your configuration entry. The field should not be final. Mark this field with the annotation `@Config`. The initial value of the field will be used as default (fallback) value. You can add a comment by setting the `comment` attribute. ```java public class Configs { @Config(comment = "This is an example!") public static String exampleString = "default"; } ``` Finally, register your `Configs` class. - For Fabric users, register the `Configs` class in your mod's `onInitialize(Client)` method. Replace `` with your mod's id. Sometimes you may omit the generics and just do `<>` instead. - On clients: ```java new ModConfigBuilder(, Configs.class).build(); ``` - On servers: ```java new ModConfigBuilder(, Configs.class).build(); ``` - For Paper users, register the `Configs` class in your plugin's `onEnable` method. Replace `` with your plugin's name. ```java new ModConfigBuilder<>(, Configs.class).build(); ``` That's it! Now you can access `exampleString` through `Configs.exampleString`. You can edit `exampleString` by using the config command. - On Fabric there are different commands for the client and server. For both, replace `` with your mod's id. - On clients, execute `/cconfig exampleString set `. - On servers, execute `/config exampleString set `. - On Paper servers, execute `/config exampleString set `. Replace `` with your plugin's name. ## That's not all! This mod also natively supports the use of `Collection`s and `Map`s as variable types. These configurations will have the options `add`, `put` and `remove` available. Moreover, you can define your own (de)serialisers to create configurations with arbitrary types. To do this, all you have to do is register the (de)serialiser when you build your config. For instance, to create configurations with type `Block` you can do ```java new ModConfigBuilder<>(, Configs.class) .registerTypeHierarchy(Block.class, new BlockAdapter(), BlockArgumentType::block) .build(); ``` where `BlockAdapter` extends `TypeAdapter` and `BlockArgumentType` implements `ArgumentType`. See [these tests](fabric/src/testmod/java/dev/xpple/betterconfig) for a complete picture. An identical setup for Paper can be found [here](paper/src/testplugin/java/dev/xpple/betterconfig). Furthermore, you can completely change the behaviour of updating your config values by creating your own methods. Simply add one or more of `setter`, `adder`, `putter` or `remover` as attribute to your `@Config` annotation. A great use for this would be adding key-value entries to a `Map` based on a single value. Consider the following configuration. ```java @Config(putter = @Config.Putter("none"), adder = @Config.Adder("customMapAdder")) public static Map exampleMapAdder = new HashMap<>(Map.of("a", "A", "b", "B")); public static void customMapAdder(String string) { exampleMapAdder.put(string.toLowerCase(Locale.ROOT), string.toUpperCase(Locale.ROOT)); } ``` The value of `"none"` for the putter indicates that no putter will be available. This way, you can use this `Map` in your code like usual, and add values to it using `/(c)config exampleMapAdder add `. For more details, see [the JavaDocs for `@Config`](common/src/main/java/dev/xpple/betterconfig/api/Config.java). The parameters of the update method can also be customised. ```java @Config(adder = @Config.Adder(value = "customTypeAdder", type = int.class)) public static Collection exampleCustomType = new ArrayList<>(List.of("%", "@")); public static void customTypeAdder(int codepoint) { exampleCustomType.add(Character.toString(codepoint)); } ``` For putters, there are separate key and value type attributes. And many more things! For some illustrative examples, see the `Configs` class for both [Fabric](fabric/src/testmod/java/dev/xpple/betterconfig/Configs.java) and [Paper](paper/src/testplugin/java/dev/xpple/betterconfig/Configs.java). ## Installation Replace `${betterconfig_version}` with the artifact version. You may choose between my own maven repository and GitHub's package repository. ### My own ```gradle repositories { maven { url 'https://maven.xpple.dev/maven2' } } ``` ### GitHub packages ```gradle repositories { maven { url 'https://maven.pkg.github.com/xpple/BetterConfig' credentials { username = project.findProperty("gpr.user") ?: System.getenv("USERNAME") password = project.findProperty("gpr.key") ?: System.getenv("TOKEN") } } } ``` Import it: ```gradle dependencies { // Fabric include modImplementation('dev.xpple:betterconfig-fabric:${betterconfig_version}') // Paper (also include the JAR in the plugins folder) compileOnly 'dev.xpple:betterconfig-paper:${betterconfig_version}' } ```
