I'd like to take input from the user and sort that input to determine which function to all next. I am having trouble finding a clear description of how this can be done. For example, if a user types "quit" or "Quit" or "QUIT" or "QUit" I want the program to recognize these as all the same input and call a function commands::quit();
Any help pointing me in the right direction would be greatly appreciated. I think part of my trouble in finding the appropriate help articles is that I am not sure what to call this process.
