Tabs count indicator

[iSeeU]

Hello,

Could you add tabs count indicator so the user know home many tabs are
opened and the position of current one?

I have a function to do it in mode line, like {2/3}
({current/total}); and another one to echo it in echo area which helps
if the info in the mode line is hidden because of how many windows I
have in a frame. This is before I knew about your wonderful package.

I imagine it will look like this:

Tabs 2/3: foo, current_tab, baz.

Maybe the current tab's count should be bold or has the same face as the
current tab's name.

Note that I didn't try your other package, tab-bar-groups, so I don't
know how this should look or if it adds complexity when both packages
are being used.

Thank you!

Thanks for your feedback, and thanks for the kind words.

I love the idea of making the Tabs: ... part at the beginning of the display more useful, especially since it's in such a prominent place.

My initial idea is to make the part that goes before the list of tabs a variable, and have it accept either a string ("Tabs: " by default) or a function that returns a string when called. That way, users can easily customize the package's output to their needs. I can also add a function that produces the output you suggested ("Tabs x/y: ") and put it into either the package or the documentation as an example.

I should be able to come up with something in the next couple days.

Thanks again for your input!

@iSeeU816, I went ahead and implemented a variation of my initial idea from above.

Here's the new variable I introduced and its docstring:

(defvar tab-bar-echo-area-display-tab-names-format-string
  "Tabs: %s"
  "Format string to use for rendering tab names in the echo area.

If the value is a string, use it as the format string.

If the value is a function, call it to generate the format string
to use.  The function is expected to take KEYMAP-ELEMENTS (the
keymap elements that will be displayed) as an argument.

The format string is expected to contain a single \"%s\", which
will be substituted with the list of fully processed tab names.")

You can use it like this to get the result you described in your original post:

(setq tab-bar-echo-area-display-tab-names-format-string
      (lambda (_keymap-elements)
        (let* ((tabs (funcall tab-bar-tabs-function))
               (index (1+ (tab-bar--current-tab-index tabs)))
               (count (length tabs)))
          (format "Tabs %d/%d: %%s" index count))))

Here's a screenshot of what that looks like:

Thanks again for your feedback and suggestion -- this package just got more useful for all of us because of it 🙌
