Starshadow Config

★ Starshadow Config

Beautiful config screens from plain Java classes.

Starshadow Config is an annotation-driven configuration library for Fabric mods. Define your settings as a simple Java class, annotate the fields, and get a polished config screen — complete with tabs, sections, sliders, toggles, and enum dropdowns — with zero boilerplate UI code.

"Config screens shouldn't require a PhD in GUI programming."

🪄 How It Works

For Mod Developers

1. Add the dependency to your build.gradle.kts
2. Create a config class with annotated fields
3. Done — Starshadow Config generates the entire screen

@StarConfig(modId = "mymod")
public class MyConfig {
    @Tab(id = "general", icon = "minecraft:crafting_table")
    @Section("scanning")
    @Range(min = 1, max = 64)
    @DefaultValue("16")
    private int scanRange = 16;

    @Section("display")
    @DefaultValue("true")
    private boolean showOverlay = true;
}

That's it. No screen builder class. No widget positioning. No layout math. Just your config fields with annotations.

For Players

If a mod uses Starshadow Config, you get:

• A tabbed settings screen accessible via Mod Menu
• Clean, consistent UI across all mods that use the library
• Sliders, toggles, and dropdowns instead of raw text fields
• Reset buttons to restore defaults

✨ Features

📝 Annotation-Driven API

Annotate your config POJO and the screen builds itself:

• @StarConfig — marks the class as a config
• @Tab — groups fields into tabs with icons
• @Section — organizes fields into labeled sections
• @Range — sets min/max for numeric fields
• @DefaultValue — defines the default value
• @EnabledWhen — conditionally enables fields based on other values
• @Hidden — excludes fields from the generated screen
• @Widget — overrides the default widget type

🔨 Fluent Builder API

Need more control? Use StarConfigBuilder for a fully programmatic approach:

StarConfigBuilder.create("mymod")
    .parent(parentScreen)
    .tab("general", tab -> tab
        .icon(Items.CRAFTING_TABLE)
        .section("scanning", section -> section
            .intSlider("scanRange", b -> b
                .range(1, 64).defaultValue(16)
                .binding(() -> config.scanRange,
                         v -> config.scanRange = v))
        )
    )
    .onSave(() -> serializer.save())
    .build();

💾 JSON Persistence

GsonConfigSerializer handles loading and saving config files as readable JSON. Files are stored in config/<mod-id>.json following Fabric conventions.

🎛️ Rich Widget Types

• Toggles for booleans
• Sliders for numbers with ranges
• Steppers for integer values
• Enum cycles for enum selections
• String fields for text input
• Description entries for informational text

🔗 Mod Menu Integration

Register your config screen with a single class:

public class MyModMenuIntegration implements ModMenuApi {
    @Override
    public ConfigScreenFactory<?> getModConfigScreenFactory() {
        return ModMenuConfigFactory.create("mymod", MyConfig.class, MyConfig::get);
    }
}

🧩 Conditional Fields

Use @EnabledWhen to create dependent settings that gray out when their condition isn't met:

@EnabledWhen(field = "pacingMode", notEquals = "ADAPTIVE")
private int linesPerSecond = 4;

📦 Installation

For Mod Developers

Add to your build.gradle.kts:

dependencies {
    modstitchModImplementation("com.starshadow:starshadow-config:${property("starshadow_version")}")
    modstitchModImplementation("com.starshadow:starshadow-lib:${property("starshadow_version")}")
    include("com.starshadow:starshadow-config:${property("starshadow_version")}")
    include("com.starshadow:starshadow-lib:${property("starshadow_version")}")
}

For Players

Starshadow Config is bundled inside mods that use it — you typically don't need to install it separately. If a mod requires it as an external dependency:

1. Install Fabric Loader for your Minecraft version
2. Install Fabric API
3. Drop the Starshadow Config and Starshadow Lib .jar files into your mods/ folder
4. Launch Minecraft

Supported: Minecraft 1.20.1 · 1.20.4 · 1.21.1 — Fabric only
