Synchronized Sync (Mode 2026)

[ThatOneCalculator]

Deprecates the Alacritty synchronization option for Mode 2026 (https://gist.github.com/christianparpart/d8a62cc1ab659194337d73e399004036)

@karlstav Tested in ghostty, alacritty, kitty, and gnome console. This is a naive implementation but it does seem to work.

hi @ThatOneCalculator,

sorry for the late feedback. There is one thing I don't understand. Why is there both a begin and end update before and after the draw function? Shouldn't there be BSU (2026h) before (line 1101) and ESU (2026l) after (line 1152)?

[ThatOneCalculator]

To be honest, this was a very naive implementation -- I did it to the point where it worked, but I think that I probably made a mistake or two along the way. I am not a C programmer nor a terminal UI programmer, but this fixed works for me, although I doubt it's the right way to do things. Something about having the update go through even though it immediately gets ended makes ghostty not tear. I think it could probably work as you described having the BSU before and the ESU after. Feel free to change my implementation!

If it works, it works. A couple of things though: if the old alacritty sync thing has not been deprecated by alacritty i think we should keep it along side this one. Also I think this sync method also must be a config option and that it must be default off. Never know if it can cause issues.

Afaik alacritty now uses the new standard. Tested this on kitty/ghostty/alactitty/foot and all worked

[karlstav]

noted, alacritty/alacritty#7365

just re apply the config option (I still believe it should be optional) and squash the commits and then I can merge

[ThatOneCalculator]

Should hopefully be able to do soon :D

[ThatOneCalculator]

Oh shit I kinda forgot about this

[ThatOneCalculator]

@karlstav there we go! Sorry about the very long delay

[ThatOneCalculator]

Tested properly now. Works completely as expected!

[karlstav]

no problem, hmm looks like I can squash the commits when i merge, i did not know that. seemed excessive with 10 commits for the 5 lines of code change.
