Description

Tmux build for CentOS and Fedora based on the official tmux spec file from https://src.fedoraproject.org/rpms/tmux/

Installation Instructions

Optional setup

**The following are for gnome-terminal. Adjust accordingly for the terminal of your choice. **

tmux.conf

For the whole range of tmux capabilities depending on your ncurses-term version set the following in your .tmux.conf

(Enable what you need from the 'as terminal-overrides' although it does not matter if they are enabled anyway)

# TERM options
set -g default-terminal "tmux-256color" # This is the correct option.
# set -g default-terminal "xterm-256color"   # Centos 7.7 does not have tmux terminfo so we need to use xterm-256color. (DO NOT use screen-256color)
set -ga terminal-overrides ",*256col*:Tc"  # true colous support
set -as terminal-overrides ',*:sitm=\E[3m' # Italics support for older ncurses
set -as terminal-overrides ',*:smxx=\E[9m' # Strikeout
set -as terminal-overrides ',*:Smulx=\E[4::%p1%dm'  # undercurl support
set -as terminal-overrides ',*:Setulc=\E[58::2::%p1%{65536}%/%d::%p1%{256}%/%{255}%&%d::%p1%{255}%&%d%;m'  # underscore colours

You can also check man tmux for more information. Also check ncurses terminfo.src for the escape characters.

Make sure that your terminal supports the above before you start blaming tmux.

True colours

For True Colour support see https://gist.github.com/XVilka/8346728

or just run

awk 'BEGIN{
    s="/\\/\\/\\/\\/\\"; s=s s s s s s s s;
    for (colnum = 0; colnum<77; colnum++) {
        r = 255-(colnum*255/76);
        g = (colnum*510/76);
        b = (colnum*255/76);
        if (g>255) g = 510-g;
        printf "\033[48;2;%d;%d;%dm", r,g,b;
        printf "\033[38;2;%d;%d;%dm", 255-r,255-g,255-b;
        printf "%s\033[0m", substr(s,colnum+1,1);
    }
    printf "\n";
}'

The colours should continuous. If there are distinct regions then it does not support true colours.

Colour codes

https://askubuntu.com/a/528938 https://misc.flogisoft.com/bash/tip_colors_and_formatting

echo -e "\e[1mbold\e[0m"
echo -e "\e[3mitalic\e[0m"
echo -e "\e[3m\e[1mbold italic\e[0m"
echo -e "\e[4munderline\e[0m"
echo -e "\e[4:3mundercurl\e[0m" 
echo -e "\e[9mstrikethrough\e[0m"
echo -e "\e[31mHello World\e[0m"
echo -e "\x1B[31mHello World\e[0m"

That should blink, have undercurl, and the range of colours should be the same inside and outside tmux

echo -ne \\e\[1\;3\;4:3\;5\;53\;38\;2\;255\;127\;0\;58\;2\;0\;48\;255\;48\;2\;255\;0\;{0..255..8}mX \\e\[0m\\n

Neovim and undercurl

If neovim does not have undercurl support during ssh sessions check if '$VTE_VERSION' is set.

Check the VTE_VERSION of your local machine

echo $VTE_VERSION  # 5803

Set the same on the remote machine

export VTE_VERSION=5803
