No syntax highlighting in iTerm2 -> ssh -> tmux (next-3.3) -> vim (8.2) #85

With the above configuration and these tmux settings:

set -g default-terminal "screen-256color"
set -ga terminal-overrides ",xterm-256color:Tc"

There is no syntax highlighting with this vimrc:

   syntax enable
   set termguicolors
   # add lines here
   call dein#add('lifepillar/vim-solarized8')
   colo solarized8
   set bg=light

I have verified with this awk script that I get a smooth gradient outside of vim.

I had to add the lines 

   let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
   let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"

to the position marked above. Then it works.

Turns out this is stated in the readme … https://github.com/lifepillar/vim-solarized8#troubleshooting Sorry for the spam.

Hate to revisit this, but after some time, the same remote machine with the above settings and versions again exhibits this problem:

What troubleshooting can I do here?

Not sure. What if you uncomment the following lines in your tmux conf?

set -g default-terminal "screen-256color"
set -ga terminal-overrides ",xterm-256color:Tc"

Shouldn't the terminal be the same in those two lines?

Also, is termguicolors set? Do you get correct (approximate, of course) colors if you :set notermguicolors?

These are some ideas off the top of my head. This is not an issue with the color scheme, but with the environment. You may get better help from Vim users's list.
