Fast Remapper

A Fast Java jar remapper.

Supports all mapping formats supported by SrgUtils.

The primary purpose of this tool is to remap Minecraft, specifically with Mojang official mappings. Please ensure you are adhering to Minecraft's EULA, and Proguard log Copyright notice.

Usage:

-e, --exclude <String>   Excludes a class from being remapped. (startsWith   
                           check)                                            
-f, --flip               Flip the input mappings. (Useful for proguard logs) 
-h, --help               Prints this help                                    
* -i, --input <Path>     Sets the input jar.                                 
* -m, --mappings <Path>  The mappings to use. [Proguard,SRG,TSRG,TSRGv2,Tiny,
                           Tinyv2]                                           
* -o, --output <Path>    Sets the output jar.

Client Example: java -jar FastRemapper-all.jar --input 1.16.5-client.jar --mappings 1.16.5-client.txt --flip --output 1.16.5-client-mapped.jar
Server Example: java -jar FastRemapper-all.jar --input 1.16.5-server.jar --mappings 1.16.5-server.txt --flip --output 1.16.5-server-mapped.jar --exclude "com.google.,com.mojang.,io.netty.,it.unimi.dsi.fastutil.,javax.,joptsimple.,org.apache."

Noteworthy items:

• --flip should be used when dealing with proguard logs (Official mappings).
• --exclude can be used to exclude individual files, or packages. Supports comma seperated list of partial or full class names. (String.startsWith)

Limitations:

• Does not support mapping with reference libraries for inheritance. (Needed for remapping Mods or libraries.)
• Does not support formats which contain parameter or local variable names.

Builds:

Builds can be downloaded directly from maven.
If you intend to run the tool standalone from the command line use the '-all.jar'.

TODO:

• Reference libraries for inheritance.
• Configurable local variable rewriting.
• Make it faster!
