Support for International keyboards

[forthrin]

When I press the + key on my keyboard, - is echoed to the log file.

Evidently, an American keyboard is assumed.

Suggest to add support for International keyboards.

Suppose there is a system call that can do the translation.

Yes, US layout is hard-coded. See:

// The following method converts the key code returned by each keypress as
// a human readable key code in const char format.
const char *convertKeyCode(int keyCode, bool shift, bool caps) {
    switch ((int) keyCode) {
        case 0:   return shift || caps ? "A" : "a";
        case 1:   return shift || caps ? "S" : "s";
        case 2:   return shift || caps ? "D" : "d";
        case 3:   return shift || caps ? "F" : "f";
        case 4:   return shift || caps ? "H" : "h";
        case 5:   return shift || caps ? "G" : "g";
        case 6:   return shift || caps ? "Z" : "z";
        case 7:   return shift || caps ? "X" : "x";
        case 8:   return shift || caps ? "C" : "c";
        case 9:   return shift || caps ? "V" : "v";
        case 11:  return shift || caps ? "B" : "b";
        case 12:  return shift || caps ? "Q" : "q";
        case 13:  return shift || caps ? "W" : "w";
        case 14:  return shift || caps ? "E" : "e";
        case 15:  return shift || caps ? "R" : "r";
        case 16:  return shift || caps ? "Y" : "y";
        case 17:  return shift || caps ? "T" : "t";
        case 18:  return shift ? "!" : "1";
        case 19:  return shift ? "@" : "2";
        case 20:  return shift ? "#" : "3";
...

I could change 19 and 20 to " and £ for the UK layout for example. One could also edit this to flip QWERTY to AZERTY (#14), but the plain letters are the easy bit. What about accents and deadkeys? Logging at a different point in the OS might give you characters...

It makes me think recording the numerical keycodes would be simpler, and/or post-processing the keylog in a scripting language aware of the actual layout in use?

Ask https://labs.perplexity.ai/: Does macOS have a system call to convert numeric keyboard values (0=A, 1=S, etc.) to whatever international keyboard the user has installed?
