  decompile [opts]
  compile [opts]
  lint [opts]
Compiler options:
  -s, --src SRC        source file or directory
  -b, --bundle BUNDLE  redscript bundle file to read
  -o, --output OUTPUT  redscript bundle file to write
Decompiler options:
  -i  --input INPUT    input redscripts bundle file
  -o, --output OUTPUT  output file or directory
  -m, --mode MODE      dump mode (one of: 'ast', 'bytecode' or 'code')

You can build the project and decompile all scripts in one command:

cargo run --bin redscript-cli --release -- decompile -i '/mnt/d/games/Cyberpunk 2077/r6/cache/final.redscript' -o dump.reds

language

The scripts use a Swift-like language. You can find a brief overview of it's features in the official wiki.

You can also try it out in your browser.

For more examples, you can have a look at some projects using redscript:

editor support

There's a dedicated language server for redscript, with support for code editors:

integrating with the game

You can integrate this compiler with the game and make it compile your scripts on startup.

To set it up, you can download the redscript-mod-{version}.zip archive from the latest release and extract it in the main game directory. You should end up with the following files:

  • Cyberpunk 2077/engine/tools/scc.exe
  • Cyberpunk 2077/engine/config/base/scripts.ini

If the compiler is set up correctly it will save logs to Cyberpunk 2077/r6/cache/redscript.log whenever you start the game.
