dwm-status

dwm-status is a simple python program for setting dwm status bar. One special thing about dwm-status is, it loads or reads resources only when needed. If I'm reading CPU usage in every second it doesn't mean I have to read or load all the other resources (storage for example) each and every second right? So every dwm-status-component reads/load details independently from others.

Requirements

Install following packages:

python3 (dwm-status is a python3 program)
lm_sensors (for reading CPU details)
amixer (for reading volume)

Internet connection: this is required to get the weather details (weather details are removed from the status bar when failed to get details)

Weather Location Details:

This uses http://wttr.in/<location> endpoint to get weather details. So the location passed to Weather constructor will be replace <location> in the URL.

dwm_status.py

status_list = [
    Weather("Colombo"),
]

Volume Controls:

Volume component is listening to SIGUSR1 custom signal and triggers set_details() method. Because it's using @trigger_change_event decorator, call to this method will trigger update_status()

@on_signal
@trigger_change_event
def set_details(self):
	self.resources = self.get_details()

So if you run kill -SIGUSR1 $(pgrep dwm_status.py) in a terminal window will trigger @on_signal methods. So I automated this process using sxhkd as follows

.config/sxhkd/sxhkdrc

#------------------------------------------------------------------------------#
#                              independent hotkeys                             #
#------------------------------------------------------------------------------#
# make sxhkd reload its configuration files:
alt + Escape
	pkill -USR1 -x sxhkd

# runs when increase/decrease volume function keys are pressed
XF86Audio{Raise,Lower}Volume
    pactl set-sink-volume @DEFAULT_SINK@ {+10%,-10%} && kill -SIGUSR1 $(pgrep dwm_status.py)

Running

make sure you got the permissions to execute

chmod -R u+x dwm-status/*

run dwm_status.py in a start up script (.xinirc)

.xinitrc

<path to dir>/dwm_status.py &
