[pacman-dev] Show total progress bar

[Nathan Jones]

Hey folks,

Message about the TotalDownload option from way back in November 07:

Back then, I did not know how to draw two progress bars. Well, now I
have figured it out (and it only took ten months, not bad). I have a
really terrible patch right now which somewhat works. If everyone thinks
that having two progress bars is a good thing, then I will make a better
patch.

I don't know if it is a good thing or not. The output is a bit
overwhelming, but it is fun to look at.

To see what having two bars would look like without having to apply the
patch, try this python script:

import sys
import time

print 'pacman         [###-------]  25%'
print 'total          [##--------]  10%',
sys.stdout.flush()
time.sleep(1)
sys.stdout.write('\033[A\033[K\n\033[K\r\033[A')
print 'pacman         [#########-]  90%'
print 'total          [#####-----]  50%',
sys.stdout.flush()
time.sleep(1)
sys.stdout.write('\033[A\033[K\n\033[K\r\033[A')
print 'pacman         [##########] 100%'
print 'gcc            [##--------]  10%'
print 'total          [######----]  60%',
sys.stdout.flush()
time.sleep(1)
sys.stdout.write('\033[A\033[K\n\033[K\r\033[A')
print 'gcc            [######----]  60%'
print 'total          [########--]  80%',
sys.stdout.flush()
time.sleep(1)
sys.stdout.write('\033[A\033[K\n\033[K\r\033[A')
print 'gcc            [########--]  80%'
print 'total          [#########-]  90%',
sys.stdout.flush()
time.sleep(1)
sys.stdout.write('\033[A\033[K\n\033[K\r\033[A')
print 'gcc            [##########] 100%'
print 'total          [##########] 100%'
