Dbgee is a handy utility that allows you to launch CLI debuggers and VSCode debuggers from the debuggee side. Just start your program by a simple command in a terminal, and the debugger will automatically attach to it with zero configuration. Dbgee also has the ability to preconfigure your program to automatically start a debug session no matter how the program is started.
