Doom emacs do not render correctly the color on ssh terminal

[vincenzopalazzo]

What happened?

This is a problem that I was never able to solve and I always try to switch on another editor when I am coding on my remote machine.

However, I think that I solution should be somewhere for this kind of problem and that I am the only one that is finding this problem.

MY doom configuration with emacs 29.1 on my host machine

but the same configuration on the same file in a ssh session shows the following error

What did you expect to happen?

I think the two configurations should be shown the same. I also try to use export TERM='xterm-256color' or export TERM='xterm' but this do not work for me.

I was also thinking of using trump but this is not working very well for me.

I discussed the problem on the emacs mailing list [1]

The problem was that my theme assumes 24-bit color, and your remote machine is not advertising that capability. So I followed the emacs docs

Colors on a TTY (GNU Emacs FAQ)

and run the following commands solve my problem

$ cat terminfo-custom.src

xterm-emacs|xterm with 24-bit direct color mode for Emacs,
  use=xterm-256color,
  setb24=\E[48\:2\:\:%p1%{65536}%/%d\:%p1%{256}%/%{255}%&\
     %d\:%p1%{255}%&%dm,
  setf24=\E[38\:2\:\:%p1%{65536}%/%d\:%p1%{256}%/%{255}%&\
     %d\:%p1%{255}%&%dm,

$ tic -x -o ~/.terminfo terminfo-custom.src
