A better shim.exe file for Scoop.

Scoop, although very useful and nice to use, uses a (subjectively) terrible shim.exe file to redirect commands from scoop\shims\app.exe to scoop\apps\app\current\app.exe, because:

1. It's made in C#, and thus requires an instantiation of a .NET command line app everytime it is started, which can make a command run much slower than if it had been ran directly;
2. It does not handle Ctrl+C and other signals correctly, which can be quite infuriating.

The last issue making interaction with REPLs and long-running apps practically impossible, and having never been fixed, I set out to improve them with this repository.

shim.cpp is:

• Faster, because it does not use the .NET Framework, and parses the .shim file in a simpler way.
• More efficient, because by the time the target of the shim is started, all allocated memory will have been freed.
• And more importantly, it works better:
  • Signals originating from pressing Ctrl+C are ignored, and therefore handled directly by the spawned child. Your processes and REPLs will no longer close when pressing Ctrl+C.
  • Children are automatically killed when the shim process is killed. No more orphaned processes and weird behaviors.

Note: This project is not affiliated with Scoop.

Installation

• In a Visual Studio command prompt, run cl /O1 shim.c.
• Or using clang++ with clang++ shim.cpp -o shim.exe -m32 -O -std=c++17 -g.
• Replace any .exe in scoop\shims by shim.exe.

An additional script, repshims.bat, is provided. It will replace all .exes in the user's Scoop directory by shim.exe.
