Comment (by ppurka):
I use a much shorter function in my zshrc to set up the git status, the
idea being that the shell should be fast in initialization and in
returning
the prompt. So, the only command that is run is `git status` and
everything
else is gleaned from that using shell operations. Also, I use `RPROMPT` so
that the left prompt is short. The `RPROMPT` disappears automatically once
the user starts typing too long commands.
{{{#!sh
function __check_git__() {
local _s="$( git status 2>&1 )"
[[ "${_s}" = "fatal:"* ]] && echo "" && return
_s="$( echo "${_s}" | sed -e '/^#.*modified:.*(untracked content)$/d'
)"
local _g_s="$( echo "$_s" | sed -n -e '1s@^On branch @@p;q' )"
if [[ "$_s" = *modified:* || \
"$_s" = *"new file:"* || \
"$_s" = *"Your branch is behind"* || \
"$_s" = *deleted:* || \
"$_s" = *renamed:* \
]]; then
echo "[%20>...>%{$fg[red]%}$_g_s%{$fg[white]%}%>>]"
elif [[ -n "$_g_s" ]]; then
echo "[%20>...>%{$fg[green]%}$_g_s%{$fg[white]%}%>>]"
else
echo "%{$fg[yellow]%}[?]%{$fg[white]%}"
fi
}
RPROMPT="%{$fg[white]%}•$(__check_git__)%{$fg[cyan]%}%n%{$fg[white]%}|%{$fg[green]%}%m%{$reset_color%}"
}}}
