Make tqdm(disable=None) default, instead of tqdm(disable=False)

• I have marked all applicable categories:
  • documentation request (i.e. "X is missing from the documentation." If instead I want to ask "how to use X?" I understand [StackOverflow#tqdm] is more appropriate)
  • new feature request
• I have visited the [source website], and in particular
  read the [known issues]
• I have searched through the [issue tracker] for duplicates
• I have mentioned version numbers, operating system and
  environment, where applicable:

  import tqdm, sys
  print(tqdm.__version__, sys.version, sys.platform)

From my personal experience (and many others), a progress bar is a great tool in developing but a nightmare for cronjob and logs. It's hard (if not impossible) to find a case in which writing a progress bar to a log file can be justified as good, or even necessary. I think it would be a wise choice to turn tqdm's output off to all non-TTY outputs BY DEFAULT.

Very much agree with this sentiment. Let's get #1343 merged.

+1 for disable=None by default.

I noticed that this issue and the attached PR are stale. I'd be happy to help get this merged if needed.
