ETA

This is a python package that will create progress bars for command-line programs.

Example usage:

from eta import ETA
eta = ETA(ticks)
for foo in bar:
    eta.print_status()
eta.done()

Or, file based usage (calls tell() to get progress)

fobj = open(fname)
eta = ETA(os.stat(fname).st_size, fileobj=fobj)

for line in fobj:
    eta.print_status(extra="extra message")
    ...
eta.done()

The output is something similar to:

20.0% - 0:04 [====>               ] ETA: 0:17 (Optional messages go here)
