dist: Arch Linux.
I have an st build from AUR and tmux from official repo. In st I meet a good TrueColor support that works with last Vim version via termguicolors option. But when i tried to bring this to tmux i faced some issues.
At first time the output of
tmux info | grep Tc
from inside of tmux was
197: Tc: [missing]
after reading tmux man page i found that this option must bring to tmux Tc
set-option -g terminal-overrides "st-256color:Tc"
where from my terminal emulator it returns me:
But the result of tmux info still was the same. Just for check i installed xterm and tried the same manipulation with it but it didn't give me another result. After all tmux recognizes that terminal support 256 colors and emulates true color via it
