Use DOM codes to identify keys

[vxgmichel]

Specification of DOM keys:

This means gambaterm now uses physical location on the keyboard which do not depend on the current keyboard layout. This allows AZERTY and Bépo users to play without changing their layout.

This means we now use the "base layout key" from the kitty keyboard protocol and scan codes from pynput, which we then translate using the dom_code_data.inc chromium table

Very cool, I'm still working on replacing python-prompt-toolkit and the custom kitty keyboard protocol support with my blessed library, I also implemented this "physical location" support there, I was just in the phase of testing and updating the README so I'm glad you're doing the same, I'll rebase my work off of this branch and submit soon

@jquast Thanks, that was quite a rabbit hole.

I also noticed that ghostty and kitty do not report the same alternate keys:

In kitty, when pressing IntlBackslash:

\ PRESS \
CSI 92 :  : 60 ;  ; 92 u
Alternate key: < 

In ghostty:

\ PRESS \
CSI 92 ;  ; 92 u

I think kitty is right in that case. EDIT: I reported it

Also I did not test it on windows and macos, that's why it's not merged yet.

I'll rebase my work off of this branch and submit soon

Awesome. Migrating to blessed was the next item in my todo list, but if you already have something I'll wait for your PR :)

I also got slowed down a bit by testing, but so far the blessed transition is looking good, I will rebase and continue testing again soon. I also reported a bugfix, in Contour, and several fixes in the blessed library, so I am glad to see your gambaterm project has been useful for fixing many other projects :)

I also reported a bugfix, contour-terminal/contour#1922

Investigating and fixing race conditions in other's projects?? That's real dedication to open source software :)

I also got slowed down a bit by testing

No hurry, I still have a couple of things to investigate here and there.

And another :) contour-terminal/contour#1924
