Append this to your ~/.zshrc file.
function preexec() {
timer=$(($(date +%s%0N)/1000000))
}
function precmd() {
if [ $timer ]; then
now=$(($(date +%s%0N)/1000000))
elapsed=$(($now-$timer))
export RPROMPT="%F{cyan}${elapsed}ms %{$reset_color%}"
unset timer
fi
}
Remixed from @adri's snippet.
@kimonoki Getting the same error:
bad math expression: operator expected at 'N/1000000'
timer=$(($(date +%s%0N)/1000000))
- error$(($(date +%s)/1000000))
- no errorI am not sure here myself using only
%s
instead of%s%0N
does work for me but nanoseconds throws an error...
