On a tangent, it would be awesome to have tmux for Windows Terminal without WSL (i.e. a native windows app). I've remapped Windows Terminal shortcuts to be like tmux bindings which gets me closer but it's still not the same.
At first I was afraid the project would take the easy way out and ignore hard features or take shortcuts (ex: SGR1 : bold or bright? or both? or none?) but you have shown you are willing to do what it takes to properly support applications.
This is not just in line with the reputation of Microsoft when it comes to backwards compatibility, but going above and beyond to make sure everything works perfectly.
When sixel support is added to WT, it will replace mintty as my favorite terminal -- and I'm very picky when it comes to terminals.
WT is a wonderful contribution to the open source world, and I hope it will inspire similar terminals on Linux (or be usable through wine)
Oh, and uh, my apologies if you felt my contribution to the sixel thread (PR #448) were out of line. Since your last message, I've realized my posts may be off topic, as a degraded mode is not what most people may want, even as a stopgap measure, so I've stopped posting there.
Or compile it yourself using MinGW64 : after installing from msys2.org, pacman -S base-devel etc
It works fine here. I have a Windows Terminal settings to start sixel-tmux instead of bash, using script to provide a pty: just have the command line be:
C:/msys64/usr/bin/env.exe MSYS=winsymlinks:nativestrict MSYSTEM=MSYS /usr/bin/script -c /usr/bin/tmux /dev/null
It's due to a cygwin and how /dev/cons* are different from /dev/pty* cf https://cygwin.com/pipermail/cygwin/2020-May/244878.html
I've tried to explain that a bit better in server-client.c (check line 251) to give the user a clue of what's happening with *cause = xstrdup(c->ttyname)
Unfortunately, even in 2021, properly configuring a terminal can be complicated.
That's why sixel-tmux page has a step-by-step configuration guide, and why I often provide config files in other projects like https://github.com/csdvrx/indent-rainbow : if needed, check https://github.com/csdvrx/indent-rainbow/blob/main/config/wi... even if I need to update it that should give you a good base to start tweaking from.
I strongly encourage you to check your configuration with the steps suggest on the sixel-tmux page, or at least the minimal set of steps shown in http://github.com/csdvrx/sixel-testsuite (which I should update to show how font change should work, with sixels being resize to be kept in perfect alignment with the text, as done in mintty, as several people seem to believe it's a sixel limitation)
