specify bar width format-spec

[Firesphere]

• 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)

I can't find it, maybe I'm stupid, but I'd like to be able to set a width for the right side data (something like this)

Messages            : 100%|█| 99/99 [00:02<00:00, 36.14it/s]
Message             : 100%|█| 3/3 [00:00<00:00, 544.17it/s]
Channels            :  95%|█▏           | 36/38 [08:54<00:22, 11.18s/it]
Relations           : 100%|█| 99/99 [00:00<00:00, 157.06it/s]

It would be nice, to make it possible to align the end of the bar (channels is the awkward one here)

Not quite sure what you mean. Can you post a minimal working example?

Hi, sorry for the delayed reply. What I would like to achieve, is the data on the right side of the progress bar, to be aligned vertically, as ljust gives the opportunity to do it for the left side:

As you can see, the progress bars don't align neatly at the far end, right, due to differences in length of the set given. I'd like to be able to make it a smooth way down.

I second this, right now my progress bars jump annoyingly if the it/s goes from say 90 it/s to 100 it/s. I really want a fixed width bar.

[casperdcl]

you can specify an ncols for a fixed bar width

[casperdcl]

you can also use set_postfix_str() with your own justified string representation of your dictionary

[crogre]

using bar_format() I could get (almost) my desired behavior by supplying format values for all the variables. What I would have liked though would be to set say {bar:20}, to make the bar fixed width. Setting all the others is not easy (times and speeds are tricky).

[casperdcl]

right, got it

[Firesphere]

Thanks for explaining the wished outcome clearer than I could @crogre :)

Yeah, having a fixed with for both left and right, or a fixed with for just the bar, would save a lot of jumping around of the bar.

A default width of a certain amount of characters for the right part would possibly also save a lot of jumping around.

What I would like to see is a fixed width for the bar itself:

1. User can easily control the width of the l_bar side (description, even across multiple positioned bars).
2. Allow the bar width to be fixed, i.e. bar_width=30
3. Using dynamic_ncols, whatever space is left is allocated to the right side of the bar, and the content is truncated to fit on the screen.

This would prevent the bar from resizing as postfix changes.

btw for now something like bar_format='{l_bar}{bar}|{r_bar:>60} might work
