Battery Indicator

This is a simple battery indicator. Depending on the value of from_acpi it either uses the system command acpi or processes data from the /proc filesystem. To use it place the following code in your wmiirc_local.py file. Please note, that monitors in wmii are sorted alphabetically by their function names, so you might want to change the name as you see fit.

The trem function is a helper function used to convert seconds to the format hh:mm:ss. info_path and state_path point to virtual files containing relevant information regarding the battery.

 ###
 import subprocess

 from_acpi = False 
 #Read battery data from 'acpi' command. 
 #If set to 'False' read data from /proc filesystem
 info_path = '/proc/acpi/battery/BAT0/info'
 state_path = '/proc/acpi/battery/BAT0/state'
 infostr = open(info_path)
 statestr = open(state_path)

 def trem(sec):
 """Convert number of seconds to the format hh:mm:ss"""
 h = sec / 3600
 m = (sec - h * 3600) / 60
 s = (sec - h * 3600 - m * 60)
 return '%02d:%02d:%02d' % (h, m, s)
