powerline-go
Powerline style prompt for your shell: Bash, ZSH and Fish
Description
- Shows some important details about the git/hg branch
- Changes color if the last command exited with a failure code
- If you're too deep into a directory tree, shortens the displayed path with
an ellipsis
- Shows the current Python virtualenv environment
- Shows the current Ruby version using rbenv or rvm
- Shows if you are in a nix shell
- It's easy to customize and extend.
To use it, add the following to your ~/.bashrc:
function _update_ps1() {
PS1="$($GOPATH/bin/powerline-go -error $? -jobs $(jobs -p | wc -l))"
# Uncomment the following line to automatically clear errors after showing
# them once. This not only clears the error for powerline-go, but also for
# everything else you run in that shell. Don't enable this if you're not
# sure this is what you want.
#set "?"
}
if [ "$TERM" != "linux" ] && [ -f "$GOPATH/bin/powerline-go" ]; then
PROMPT_COMMAND="_update_ps1; $PROMPT_COMMAND"
fi
Or to your ~/.zshrc:
function powerline_precmd() {
PS1="$($GOPATH/bin/powerline-go -error $? -jobs ${${(%):%j}:-0})"
# Uncomment the following line to automatically clear errors after showing
# them once. This not only clears the error for powerline-go, but also for
# everything else you run in that shell. Don't enable this if you're not
# sure this is what you want.
#set "?"
}
function install_powerline_precmd() {
for s in "${precmd_functions[@]}"; do
if [ "$s" = "powerline_precmd" ]; then
return
fi
done
precmd_functions+=(powerline_precmd)
}
if [ "$TERM" != "linux" ] && [ -f "$GOPATH/bin/powerline-go" ]; then
install_powerline_precmd
fi
For fish, redefine fish_prompt in ~/.config/fish/config.fish:
function fish_prompt
eval $GOPATH/bin/powerline-go -error $status -jobs (count (jobs -p))
end
