Devoldefy

Translates MCP source code to Yarn

How to use it

Download the latest release and run java -jar devoldefy.jar. You'll be asked to enter the following information:

• The source code's Minecraft version
• The source code's Forge version (this is used to get a remapped Minecraft jar from your gradle cache folder)
• The source code's mappings Minecraft version (for 1.12.2, this is 1.12)
• The source code's mappings' type (snapshot or stable)
• The source code's mappings' build (the number that follows snapshot_ or stable_)
• The source code's location (this should be the path to the src/main/java folder)
• The target Minecraft version (1.14)
• The target Yarn build number (to find out the latest, type !yv in the Fabric discord, or look here)
• The target location (where you want the updated source code to be placed - this must not be a subdirectory of the source location)

Feel free to open an issue or ping me in the Fabric discord if you need help or find a bug with the tool.
