Layer name restrictions

[finestedm]

Hi there. I've encountered an error while building config for my keeb that was caused by a wrong name of a layer, which I called
F1-F12

The usage of
-
caused the problem. It would be easier to avoid if the layer name input field disallowed such names.

Thanks!

Oof, that's annoying. Devictree syntax actually does allow the - character in node names but obnoxiously the keymap goes through a preprocessor. F1 and F12 are ZMK keycodes and are placeholders for integer values this evaluates as a mathematical expression.

I do have warnings when trying to name a layer after a keycode or other identifier exactly (e.g. just naming the layer F1) but something like this means I have to worry about almost anything being an expression.

Maybe what I'll do is show a gentle warning when the layer name includes -.
