Coverage decreased (-0.1%) to 82.061% when pulling cff7413 on bar_format_callback into c2941fb on master.

ah, nice... an update callback wrapped by another update callback.

Ah you're right, I didn't give it enough thought, this code probably
doesn't work as it is.

I think it would be better to just provide a special value to format_meter
so that it returns the dict to status_printer, so users would just have to
overload tqdm.status_printer with their bar display code, and tqdm.init
to call format_meter with the special argument like bar_format=True.

The idea is to avoid forcing the user to recode the rate, remaining and
percentage computation codes that are done in format_meter. If they have a
GUI bar, they can't just overload status_printer, as
status_printer.print_status() expects a string, and a GUI usually breaks
down the different parts of the bar into different widgets.

I think it might make sense for a call to update() to return a dict to simplify the end interface... wasn't finding fault; thought it was a good idea.

from tqdm import tqdm

def callback_gen(t, ...):
  def inner(...):
    params = t.update(dict=true)
    if params:
      # use params
  return inner

callback = callback_gen(tqdm(total=len(iter)))
for x in iter:
  callback()

I'd estimate this would add a 50% overhead on average

This should be reworked on to also provide the separate values when total=None. Also, merging this will not only help third-party devs but also our own modularization of the code, for example #223 (because then we can call parent and avoid copy/pasting the calculation code). We should then also add N_BARS as a returing argument.

Summary todo:

• also return arguments if total=None
• return N_BARS

Closing this, this should be merged with #223 as it uses bar_format_callback to reduce code duplication (not really the callback but the dict return, but if dict return works then callback will also work because this is the same code but one if branching).

Note that #223 contains bugfixes compared to the version in here, this is the reason I close this PR.
