Just as a follow-up to my question about a newline in the prompt, I ended up
settling on these lines in my config.fish file in order to get the prompt set
just the way I want, including the newline before each prompt. The default
path-shortening behavior in the prompt drives me absolutely crazy and I hate
it, so it's overridden.
The resulting prompt includes the 24-hour time in HH:MM:SS and a bash-like $
for non-root users, and looks like this:
[15:13:59] user@hostname:~/.config/fish $
or
[15:13:59] root@hostname:~/.config/fish #
config.fish:
function just_the_time --description 'Shows just the time in 24-hour format'
date +"%T"
end
function prompt_pwd --description 'Overwrite unwanted path shortening behavior'
if test "$PWD" != "$HOME"
printf "%s" (echo $PWD|sed -e "s|^$HOME|~|")
else
echo '~'
end
end
function fish_prompt --description 'Write out the prompt'
# Just calculate these once, to save a few cycles when displaying the prompt
if not set -q __fish_prompt_hostname
set -g __fish_prompt_hostname (hostname|cut -d . -f 1)
end
if not set -q __fish_prompt_normal
set -g __fish_prompt_normal (set_color normal)
end
if not set -q __fish_color_clock
set -g __fish_color_clock (set_color black --bold)
end
if not set -q __fish_color_userandhost
set -g __fish_color_userandhost (set_color purple --bold)
end
if not set -q __fish_color_directories
set -g __fish_color_directories (set_color blue --bold)
switch $USER
case root
if not set -q __fish_prompt_cwd
if set -q fish_color_cwd_root
set -g __fish_prompt_cwd (set_color $fish_color_cwd_root)
else
set -g __fish_prompt_cwd (set_color $fish_color_cwd)
end
end
echo
echo -n -s "$__fish_color_clock" '[' (just_the_time) ']' ' '
"$__fish_color_userandhost" "$USER" @ "$__fish_prompt_hostname"
"$__fish_prompt_normal" ':' "$__fish_color_directories" (prompt_pwd)
"$__fish_prompt_normal" ' # '
case '*'
if not set -q __fish_prompt_cwd
set -g __fish_prompt_cwd (set_color $fish_color_cwd)
end
echo
echo -n -s "$__fish_color_clock" '[' (just_the_time) ']' ' '
"$__fish_color_userandhost" "$USER" @ "$__fish_prompt_hostname"
"$__fish_prompt_normal" ':' "$__fish_color_directories" (prompt_pwd)
"$__fish_prompt_normal" ' $ '
end
end
