Project description
nr.powerline
Simple powerline implementation, only tested in Bash. It is recommended that you use a font from NerdFonts in order to have proper support for special characters (like the right triangle).
Simple Setup
$ pipx install nr.powerline
$ PS1='`nr powerline` '
The above get's you started quickly, but you will notice a delay in rendering the powerline. This is mostly because of the overhead of kickstarting the Python process. To improve performance, Powerline can be started in the background and communicated with over a Unix socket.
function _powerline_get() {
echo "$PWD" | nc -U ~/.local/powerline/daemon.sock 2>/dev/null
return $?
}
function _powerline() {
_powerline_get
if [ $? != 0 ]; then
if which nr-powerline >/dev/null; then
nr-powerline --start
if ! ( nr-powerline --status --exit-code >/dev/null ); then
echo "Could not start powerline daemon."
else
_powerline_get
fi
else
printf "$HOSTNAME $PWD $ "
fi
fi
}
export PS1='`_powerline`'
Roadmap
- Daemon to run in the background to speed up powerline rendering.
- Pass previous status code into
nr-powerline
command. - Breadcrumb working directory
- Truecolor and xterm-256 color support
Plugins
The entry point for powerline plugins is nr.powerline.plugins
. Entry points
must inherit from the nr.powerline.plugins.Plugin
class.

The powerline can be configured with environment variables.
