tab bar does not scroll horizontally

[dead10ck]

When there are more buffers open than can fit into the bar, the ellipsis just stays at the beginning, and does not attempt to move so that you can see the current buffer highlighted. It should probably instead move which section of the bar is hidden with ellipses, so that when you are looking at a buffer near the beginning of the list, the ellipses are shown at the end, and if you are in the middle of a long list, ellipses should be shown at both left and right ends.

This is a known problem. I've thought a lot about how to implement this but I'm unsure what the best way is. I'll try see if I can implement a fix for this over the weekend. Thanks for raising this.

Ok, I've tried implementing something to solve this. Please have a look at the readme under the Overflow and Reserving Space for Tabs sections of the readme, and update to this commit (f9396b2) implements the behavior you want with the scroll mode.

Note that the scroll mode depends on luar, so please plug that as well.

Hi @enricozb thanks so much for working on this! I tried out the latest master, and it looks like scroll mode is not working. I have this config:

plug "gustavo-hms/luar" %{
    require-module luar
}

plug "enricozb/tabs.kak" %{
  set-option global modelinefmt_tabs '%val{cursor_line}:%val{cursor_char_column} {{context_info}} {{mode_info}}'
  set-option global tabs_overflow "scroll"
  map global user t ': enter-user-mode tabs<ret>' -docstring 'tabs'
  map global user T ': enter-user-mode -lock tabs<ret>' -docstring 'tabs (lock)'
}

and it looks like it is still shrinking instead of scrolling.

Thanks for trying this out! Can you send a screenshot of the behavior?

[dead10ck]

Sure, here's one. We can see all the names are cut off on the left.

@enricozb Seems this got removed when you did the clean slate commit. Any plans on it coming back?

[enricozb]

@skarekrow Which branch/commit are you using?
