Yarn is a set of open, freely licensed (CC0) Minecraft mappings that translate obfuscated Minecraft class, method, and field names into readable names. It is developed with the Enigma tool and consumed via the Fabric Loom Gradle plugin for Minecraft modding.
Use cases
- deobfuscate the Minecraft jar for reading its source code
- develop Minecraft mods with the Fabric toolchain
- browse readable names for Minecraft's obfuscated code in an IDE
- contribute improved mappings names to the community
- generate a named jar for decompilation
When to choose
- you are building Fabric mods and need readable Minecraft names
- you want mappings with a fully permissive CC0 license
- you need to decompile and study Minecraft's code
When to avoid
- you use a mod loader with its own mappings like MCP or Mojang's official obfuscation maps
- you need runtime tooling rather than static name mappings
