Parchment

What Parchment is

Parchment provides community-written parameter names and Javadocs for Minecraft mod development. The mappings add names and documentation to Mojang’s official names and are designed to work across mod loaders. They are compatible with Mojmap and can be used with Forge, Fabric, Quilt and other modding platforms. The mapping set draws on Mojang’s published obfuscation maps for Minecraft versions since 1.14; a version needs published obfuscation logs to be supported. Listed versions run from 1.16.5 through 1.21.11, covering supported releases under Parchment’s version policy. The project currently excludes snapshots because later snapshots can invalidate them. Mappings are open source and hosted publicly on GitHub, and the listed Parchment mappings plan costs nothing. Contributors are asked to use American English spelling and lower camel case for parameter names. Forge development can use the Librarian Gradle plugin, which requires ForgeGradle 5.1.20 or later and Gradle 7.1.1 or higher. Fabric Loom includes native support beginning with version 0.9. Setup instructions use Parchment’s Maven repository. The ParchmentMC Team directs people with questions to its official Discord server.

Who it suits

Parchment suits Minecraft mod developers who want community-written parameter names and Javadocs that work across loaders. It is relevant to Forge, Fabric and Quilt projects, including teams working with supported Minecraft versions that have published obfuscation logs.

Limits

Parchment supports versions with published obfuscation logs and only the latest minor version of each maintained major release. Snapshot versions are not currently mapped.
