Overview

Myotus is a library-first extension layer for Applied Energistics 2 terminals.

It is not designed as a large standalone gameplay mod. In 1.20.1, it provides a shared place for:

• optional mod integration registration
• item-list integration markers and subscriber dispatch
• terminal configuration tab registration
• runtime integration checks
• terminal-side UI helpers
• annotation-driven commands

Who should use it

• Players who install another mod that depends on Myotus and need to understand the terminal settings it exposes.
• Addon developers who want to attach optional behavior to AE2 terminals without rebuilding loader checks and config-tab plumbing.
• Maintainers supporting Forge 1.20.1 specifically or comparing it with the later NeoForge line.

Baseline

• Loader: Forge 47.4.17
• Minecraft: 1.20.1
• Java: 17
• AE2: 15.4.10

Bootstrap flow

Myotus.java performs the real startup work for this line:

1. it installs MyotusAPIImpl.INSTANCE as the active API implementation
2. it registers the built-in optional integration markers for JEI, EMI, REI, AE2WTLib, AE2FCT, and AE2TB
3. it calls MyoConfig.initialize() so Forge can write myotus-client.toml
4. it waits for common setup and then calls MyotusConfigTab.initialize() to register the terminal settings tab

Built-in integration markers

The Myotus bootstrap registers integration markers for these mod IDs in 1.20.1:

• jei
• emi
• roughlyenoughitems
• ae2wtlib
• ae2fct
• ae2tb

The repository also contains GuideME-related addon and mixin code, even though GuideME is not registered through the same marker list in the constructor bootstrap.

Important limitations

The Forge line does not include:

• MyoConfigTabContext
• MyoConfigTabVisibility
• MyoModCondition
• ITerminalUpgradeCard
• persistent terminal upgrade storage

Where to go next

• Installation for runtime requirements.
• Project Structure for package and resource layout.
• Configuration for the keybinding and client config.
• Item List Integrations for JEI, EMI, and REI subscriber flow.
