+# Advanced configuring - WORK IN PROGRESS
+
+Simple values are nice and all, but if you have a lot of them it can begin to get unwieldy. In this tutorial, we'll discuss how to organise your config and use processors to get the most out of it.
+
+## Using sections
+
+A flat file of dozens of values can get hard to navigate fast, and not to mention confusion. Luckily we can organise it into sections using Quilt Config! This is super simple to get up and running:
+
+`src/main/com/example/example_mod/ExampleModConfig`:
+
+```java
+public class ExampleModConfig extends ReflectiveConfig {
+	// ...
+    @Comment("Advanced settings for advanced users.")
+    @SerializedName("advanced_settings")
+	public final AdvancedSettings advancedSettings = new AdvancedSettings();
+
+	public static class AdvancedSettings extends Section {
+		@Comment("Whether to automatically append newlines to every message printed.")
+		@SerializedName("print_newlines")
+		public final TrackedValue<Boolean> printNewlines = this.value(true);
+	}
+}
+```
+
+We simply create a new class, inside our config class, that extends `ReflectiveConfig.Section`. Then we have to create another object inside the main config to add the section. Note that this instance of our section is **not** stored inside a `TrackedValue` like everything else, instead it stores `TrackedValue`s inside itself! Now that we have a section, we can add as many values as we want inside. But what if we want to store something more interesting than a basic type, map, or list? Let's serialize a custom object.
+
+## Serializing custom values
+
+In Java, you can print to different output streams in the console. These aren't basic integer or float objects, so we can't just save them in our config! This is where the `ConfigSerializableObject<T>` interface comes in. By implementing its three methods, we can set up any class to be usable as a config object.
+
+The interface works via generics, just like `TrackedValue`. The `<T>` in `ConfigSerializableObject<T>` can be swapped out with any serializable class (remember, by default that's primitive types, `String`, `ValueList`, and `ValueMap`), and the value of your object will be translated into that type to be saved to disk, and then converted back into your custom object when read. To do that translating, we need to implement three methods:
+- `T getRepresentation()`: here, your value is converted to the serializable class that you specified in the generics (represented by `T`) so that it can be saved.
+- `YourSerializableClass convertFrom(T)`: this one is called when reading the config file, and converts the representation created by `getRepresentation` back to its original type.
+- `YourSerializableClass copy()`: makes a copy of the value, which Quilt Config uses internally.
+
+Enough with the explanations: let's see an example!
+
+```java
+public class ExampleModConfig extends ReflectiveConfig {
+	// ...
+	public static class AdvancedSettings extends Section {
+		// ...
+		@Comment("What stream to print the message to.")
+		@SerializedName("print_stream")
+		public final TrackedValue<PrintStreamOption> printStream = this.value(PrintStreamOption.SYSTEM_OUT);
+
+		@SuppressWarnings("unused") // IDEs won't understand that all options in this enum can be used via the config
+		public enum PrintStreamOption implements ConfigSerializableObject<String> {
+			SYSTEM_OUT(System.out),
+			SYSTEM_ERROR(System.err);
+
+			private final PrintStream printStream;
+
+			PrintStreamOption(PrintStream stream) {
+				this.printStream = stream;
+			}
+
+			public PrintStream getStream() {
+				return this.printStream;
+			}
+
+			@Override
+			public PrintStreamOption convertFrom(String representation) {
+				return valueOf(representation);
+			}
+
+			@Override
+			public String getRepresentation() {
+				return this.name();
+			}
+
+			@Override
+			public PrintStreamOption copy() {
+				// enum values cannot be duplicated
+				return this;
+			}
+		}
+	}
+}
+```
+
+This may look like a lot of code, but we've already covered most of it! We're using an `Enum` here, which allows us to clearly define a set of options for our value. If you wanted, you could use a regular class and have an infinite number of possibilities for your config field! An additional benefit of using an `Enum` is that Quilt Config will automagically generate a comment with the possible values in the serialized config file.
+
+The implementation of `ConfigSerializableObject<T>`'s methods is incredibly simple here: since the values in our enum already have names, we just use the methods `name` and `valueOf(String)` to serialize and deserialize respectively. Cute! Let's look at another example of a custom object that can't be represented in an enum.
+
+Let's say we want to store a point on a 3d grid in the config. We would need to store both an `x` coordinate, a `y` coordinate, and a `z` coordinate for that value. Let's do that! This is simply an example, and won't be used in our mod.
+
+```java
+public class Vec3i implements ConfigSerializableObject<ValueMap<Integer>> {
+	public final int x;
+	public final int y;
+	public final int z;
+
+	public Vec3i(int x, int y, int z) {
+		this.x = x;
+		this.y = y;
+		this.z = z;
+	}
+
+	@Override
+	public Vec3i copy() {
+		return this;
+	}
+
+	@Override
+	public Vec3i convertFrom(ValueMap<Integer> representation) {
+		return new Vec3i(representation.get("x"), representation.get("y"), representation.get("z"));
+	}
+
+	@Override
+	public ValueMap<Integer> getRepresentation() {
+		return ValueMap.builder(0)
+				.put("x", this.x)
+				.put("y", this.y)
+				.put("z", this.z)
+				.build();
+	}
+}
+```
+
+Here we leverage a `ValueMap` instead of a `String` as the serialized type. This allows us to easily distinguish between the `x`, `y`, and `z` fields, and is the data type you'll nearly always use when serializing complex objects like this.

+## Changing the config format
+
+Let's get into how you choose a file format to save to. Quilt Config currently only provides two serializers: `json5`, an extension of the JSON format to allow cleaner syntax and comments, and `toml`, which is the default format it serializes to. If you want to switch to `json5`, we can do that using a `Processor`!
+
+This processor needs to run before the config is read, so we're going to place it directly on the class:

+# Getting started with Quilt Config
+
+[Quilt Config](https://github.com/QuiltMC/quilt-config) is Quilt's advanced configuration API. It allows developers (that's you!) to easily set up values that can be changed by the user in order to change the behaviour of your mod. It's built into [Quilt Loader](https://github.com/QuiltMC/quilt-loader) to allow any Quilt mod to leverage it without having to pull in new dependencies or run any setup.
+
+## Setting up your config
+
+In this tutorial, we're going to be building a simple mod that prints a line of text to the console when it's initialized. Keep in mind that this is an example, and your mod can use config values anywhere you want! You can view of the final source code of this tutorial [on GitHub](https://github.com/ix0rai/quilt-config-example-mod).
+
+To begin with Quilt Config, you'll need a dedicated class for holding your config. For an extremely configurable mod, you may want to break up your config into multiple files inside a `config` package, but for this tutorial and most mods we're going to put everything in one file.
+
+Let's create a new file for our config, in the same directory as our mod initializer. We'll call it `ExampleModConfig`, but you can call it whatever you want. This new config class will extend the `ReflectiveConfig` API, which will provide everything we need to get the config working.
+
+We'll start with this code:
+
+`src/main/com/example/example_mod/ExampleModConfig`:
+
+```java
+public class ExampleModConfig extends ReflectiveConfig {
+	public static final ExampleModConfig INSTANCE = QuiltConfig.create(ExampleMod.MOD_ID, ExampleMod.MOD_ID, ExampleModConfig.class);
+}
+```
+
+Now that big line in the middle may seem intimidating, but we're going to break it down.
+- First, `public static final` means that the value never changes (though data *stored* in the config can), and `instance` is a fancy programmer word that just means it's an object of a class.
+- Second, we're calling the method `QuiltConfig.create(String family, String id, Class<C> configCreatorClass)`. As you can see, it takes three parameters:
+  - The string `family`, which indicates the directory that your config file will be stored in, relative to the global config directory (usually `<your instance directory>/config`). We're using our mod ID as the directory, and that's the best practice.
+  - A second string, `id`, which will be the name of the configuration file (before the file extension is added, which changes depending on the format you choose). Here we use our mod ID once again, but if you have a complicated config with multiple files you'll want to use a different name.
+  - Finally, something confusing: what is a `Class<C> configCreatorClass`? We're not going to worry too much about the details: just pass in the name of your config class with `.class` appended, as we've done here with `ExampleModConfig.class`.
+
+## Adding values
+
+That's it! We now have a config that we can access anywhere in our project. Problem is, there's no reason to access it because there's nothing there. Let's fix that by adding a value! Our example mod prints a line of text to the console when started up: why don't we allow the user to decide what that line is. Let's add a second field to our config:
+
+`src/main/com/example/example_mod/ExampleModConfig`:
+
+```java
+public class ExampleModConfig extends ReflectiveConfig {
+	// ...
+	public final TrackedValue<String> message = this.value("rai minecraft :thumbsup:");
+}
+```
+
+We're introducing a bunch of things with one line again. Lovely! Let's dig into it:
+- This value is `public final`, which means that instead of being accessible by anything you need an instance of `ExampleModConfig` first. Since we defined our `INSTANCE` field already, we'll be able to access this from anywhere via `ExampleModConfig.INSTANCE.message`.
+- The type is `TrackedValue<String>`. The angle brackets (`<>`) allow us to use what's called *generics*, which in Java are a way to adapt a class to your specific use case. Here, the `TrackedValue` class allows us to adapt the type of object it holds, so we use it to store a `String`. Thanks to the generics, we could put another type inside those brackets later to store a different kind of value! This is foreshadowing. We're going to store some different values. Get ready.
+- We call the `value` method, which comes from the `ReflectiveConfig` class we're extending. This method takes one parameter, which will be the default value of that config field. Here, the author of this tutorial is using it to self-advertise.
+
+Phew. We got through it! That'll be the final big information dump of this tutorial, and we can begin having some fun. Now that we have a field in our config, we can pop back over to our mod initializer and start using it!
+
+`src/main/com/example/example_mod/ExampleMod`:
+
+```java
+public class ExampleMod implements ModInitializer {
+	// ...
+
+	@Override
+	public void onInitialize(ModContainer mod) {
+		LOGGER.info(ExampleModConfig.message.value());
+	}
+}
+```
+
+Since the `message` field is a `TrackedValue<String>` instead of a simple `String`, we need to call the `value` method on it to get its value to print. We'll also be able to use the `setValue` method to change the value from code.
+
+Now our mod prints a custom message to the console on startup! While this would already get us an easy 1 million downloads, Quilt Config allows us to do so much more.
+
+## Using annotations
+
+Let's add a second field. Here we're going to get fancy with it, using both a new data type and one of Quilt Config's many fancy annotations.
+
+`src/main/com/example/example_mod/ExampleModConfig`:
+
+```java
+public class ExampleModConfig extends ReflectiveConfig {
+	// ...
+	@IntegerRange(min = 0, max = 10)
+	public final TrackedValue<Integer> timesToPrint = this.value(1);
+}
+```
+
+We're not going to show the changes to the code to use each one of these values, but remember you can see how they're used in the [final code](https://github.com/ix0rai/quilt-config-example-mod). Let's get back on our bullet points to explain this snippet!
+- `IntegerRange` is an annotation: it adds new functionality to our field, outside the normal declaration. `IntegerRange` allows us to limit the allowed values of our `Integer` field, to between `min` and `max` (inclusively).
+- We've changed the type from `String` to `Integer`. Now, why `Integer` instead of `int` like we would use for a normal number field? `int` is a *primitive type*, which means that it isn't actually a class! Since generics can only take classes, Java provides class versions of each primitive. `boolean` becomes `Boolean`, `float` becomes `Float`, `double` becomes `Double`, `char` becomes `Character`, etc etc.
+
+Something incredibly important to remember is that you can't just send any class into `TrackedValue`'s generics: Quilt Config has to know how to serialize it. By default, all [primitive types](https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html) are serializable, as well as the `String` class. We'll cover how to explain to Quilt Config how to serialize a class later, but first: more fun with annotations!
+
+Anyway. New value!
+
+`src/main/com/example/example_mod/ExampleModConfig`:
+
+```java
+public class ExampleModConfig extends ReflectiveConfig {
+	// ...
+	@Comment("Whether to print the message at all.")
+	public final TrackedValue<Boolean> print = this.value(true);
+}
+```
+
+Here we simply leverage the `Comment` annotation to add a comment explaining exactly what the config field does. This will be saved by Quilt Config in the config file, as long as the format you use supports comments. Neat!
+
+Finally, we're going to use one more annotation to tie it all together. By default, Quilt Config serializes to [TOML](https://toml.io/en/) which has a couple standards we're not following. In Java, `public final` fields are named using `lowerCamelCase`, like our `timesToPrint` field. But, in a TOML file, names should use `snake_case`, meaning we should have named the field `times_to_print`. To match both conventions, we can use the `SerializedName` annotation!
+
+`src/main/com/example/example_mod/ExampleModConfig`:
+
+```java
+public class ExampleModConfig extends ReflectiveConfig {
+	// ...
+	@IntegerRange(min = 0, max = 10)
+    @SerializedName("times_to_print")
+	public final TrackedValue<Integer> timesToPrint = this.value(1);
+	// ...
+}
+```
+
+Problem solved! Now it'll follow the Java conventions in the Java code, and the TOML conventions in the saved TOML file. We can apply `SerializedName` annotations to every multi-word config field to solve our problems everywhere.
+
+## Maps and lists
+
+Two of the most common data structures used in Java programming are `Map` and `List`. Quilt Config provides convenient serializable versions of both of these in the for of `ValueMap` and `ValueList`!
+
+Starting with maps, `ReflectiveConfig` provides us a handy `map` method to help us easily make a default value.
+
+`src/main/com/example/example_mod/ExampleModConfig`:
+
+```java
+public class ExampleModConfig extends ReflectiveConfig {
+	// ...
+	@Comment("When a key in this map shows up in the message, it'll be replaced with the corresponding value.")
+	public final TrackedValue<ValueMap<String>> replacements = this.map("")
+		.put("oro armor", "rai minecraft")
+		.put("lambda aurora", "rai minecraft")
+		.put("tib s", "rai minecraft")
+		.build();
+}
+```
+
+There are a few things of note here:
+- We have to pass an empty string (`""`) to the `map` method, in order for it to understand that the map stores values of the type `String`. This value is not used beyond checking the type, so you can put whatever you'd like there.
+- `ValueMap` always uses `String` as the type for its keys, instead of having you pick like most Java `Map` implementations.
+- We can put as many values in the default map as we'd like. If the author wanted to replace every single Quilt developer with herself instead of just the admins, that would be possible!
+
+Now that we know how to use maps, onward to lists!
+
+```java
+public class ExampleModConfig extends ReflectiveConfig {
+	// ...
+	@Comment("This isn't actually used by the mod, but I was completely out of ideas for things to add.")
+    @SerializedName("types_of_soup")
+	public final TrackedValue<ValueList<String>> typesOfSoup = this.list("", "tomato", "borscht", "chicken noodle", "ramen", "STEW", "mushroom");
+}
+```
+
+This is pretty similar to building a list. Instead of chaining `put` calls on a builder, we simply add as many values as we want directly in the constructor. Again, the first argument is unused and is to help Quilt Config infer the type. With that, we've made an excellent little config for our mod! If you want to know more, let's move on to the [Advanced Configuring tutorial](TODO LINK).
