protonhax

Tool to help running other programs (i.e. Cheat Engine) inside Steam's proton.

Usage

Set the steam game launch options to protonhax init %COMMAND%

On your Steam Library:

• Right-click the game > Properties > General.
• Set Launch Options as protonhax init %COMMAND%.

Now, you can use your terminal to run the following commands:

• To list all running appids use
  protonhax ls

• To run a program with proton use
  protonhax run <appid> <path/to/program> [args...]
  NOTE: The PATH variable is ignored

• To run cmd.exe use
  protonhax cmd <appid>

• To run a program natively with the environment variables that were used to launch the game originally use
  protonhax exec <appid> <path/to/program> [args...]
  NOTE: The PATH variable is ignored

2. Copy the protonhax file to where you preffer and give it permission to execute:
   • Example of locations $HOME/.local/bin/protonhax, /usr/bin/protonhax. They need to be on your $PATH

Contributing

Contributions are always welcome! Especially if they are packages for other distributions.

Running programs BEFORE the game.

Protonhax is not necessary, you can set your launch options to switch paths. Example:

eval $(echo "protonhax init %command%" | sed "s|path/to/game.exe|path/to/your.exe|") More
