• I have marked all applicable categories:
  • exception-raising bug
  • visual output bug
  • 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

The CLI, if I understood correctly, counts one iteration for each newline character it reads in stdin, which it forwards to stdout. I have not seen this documented anywhere, it would be nice if it were.

The feature request is regarding this behaviour: there should be an option for different types of inputs, the first and most obvious one being receiving the number of iterations directly on standard input:

5
8
12

Such an input would make the bar progress to 5, then 8 and then 12 iterations.

My use-case is ffmpeg progress indication, where I am able to parse its frame progress into integers, but ffmpeg has no option to output such information at each frame.
