Output

A Python module providing helpers for fancy looking shell output. It is based on the output module found in Gentoo Linux but removes the dependency on portage.

Classes

EOutput

Performs fancy terminal formatting for status and informational messages as known by various init script implementations.

Example Usage:

from output.eoutput import EOutput

out = EOutput()
out.ebegin('Starting skynet')
out.eend(0)

The argument to EOutput.eend() is a standard UNIX errno code. 0 renders a success and 1 or above a error status message.

In a real world example you would usually make the result dependent an a certain condition or spit out a warning.

import random
from output.eoutput import EOutput

level = random.randint(50, 125)
out = EOutput()

out.ebegin('Starting skynet')
if level > 75:
    if level < 100:
        out.ewarn('Link power level not at full capacity. Proceeding anyway.')
    out.eend(0)
else:
    out.eend(1)

TermProgressBar

A tty progress bar similar to wget's.

Example Usage:

from time import sleep
from output.progress import TermProgressBar

pb = TermProgressBar()
for i in range(1, 100):
    pb.set(i, 100)
    sleep(0.01)

The progress bar can be useful when a routine takes some time to process and isn't verbose about what's going on. Well - it's a progress bar.

import random
from time import sleep
from output.eoutput import EOutput
from output.progress import TermProgressBar

level = random.randint(50, 125)
out = EOutput()

out.ebegin('Starting skynet')
if level > 75:
    if level < 100:
        out.ewarn('Link power level not at full capacity')
        out.einfo('Tranfering shield power to resonators')
        pb = TermProgressBar(title='Power transfer progress')
        for i in range(1, 100):
            pb.set(i, 99)
            sleep(0.05)
        print
    out.eend(0)
else:
    out.eend(1)
