How do zsh ansi colour codes work?

Question

I want to make my hostname in my terminal orange. How do I do that?

Answer 1

Running the following code in your terminal should tell you whether your terminal supports 256 colors.

for COLOR in {0..255}  do     for STYLE in "38;5"     do          TAG="\033[${STYLE};${COLOR}m"         STR="${STYLE};${COLOR}"         echo -ne "${TAG}${STR}${NONE}  "     done     echo done 

it also shows you the code for each color in the form 38;5;x where x is the code for one of the 256 available colors. Also, note that changing the "38;5" to "48;5" will show you the background color equivalent. You can then use any colors you like to make up the prompt as previously mentioned.

Answer 2

First off, I'm not sure what terminal you're using or if it will even support the color orange. Mine supports the following: Red, Blue, Green, Cyan, Yellow, Magenta, Black & White. And here's how I get colors in my terminal:

You need to first load the colors using autoload. I use the following to load the colors and assign them to meaningful names

#load colors autoload colors && colors for COLOR in RED GREEN YELLOW BLUE MAGENTA CYAN BLACK WHITE; do     eval $COLOR='%{$fg_no_bold[${(L)COLOR}]%}'  #wrap colours between %{ %} to avoid weird gaps in autocomplete     eval BOLD_$COLOR='%{$fg_bold[${(L)COLOR}]%}' done eval RESET='%{$reset_color%}' 

You can set the hostname in your prompt using the %m string. So to set, say a red hostname, you'd do

${RED}%m${WHITE}\> 

which will print something like bneil.so>

Print

<ESC>[33mHostname<ESC>[0m
