Memory Usage Indicator

This is a simple memory usage indicator based on information obtainable from the free system command.

It was written to work with wmii-3.9 and higher. To use it you have to put it 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.

inp = subprocess.Popen(['free'], shell = False, stdout = subprocess.PIPE)
out = inp.communicate()[0].splitlines() 
ram = int(out[2].split()[2])/1024
maxram = int(out[1].split()[1])/1024
swap = int(out[3].split()[2])/1024
maxswap = int(out[3].split()[1])/1024
return wmii.cache['normcolors'], 'RAM: ' + str(ram) + '/' + str(maxram) +\
    ' MB' + ' | SWAP: ' + str(swap) + '/' + str(maxswap) + ' MB'
