Request: Only show tab as active in tabline, if buffer is the currently selected split

[praveenperera]

Is your feature related to a problem?

I usually have to vertical splits open at all times. In the tab line both open buffers have the active styling. And I sometimes get confused which file I'm currently focused on.

Describe the new feature

Either:

1. Default to only showing active styling on tab in currently focused split
2. Keep current default but add easy config option to only apply the active styling to tab I'm currently focused on in a split
3. 3 states, active, active-focused, inactive

Additional context

Only one tab should have active styling.

ay I see! the difference that we have in this case is that the tab for the focused window is bold and italic and you might not be using a terminal/font that supports bold/italics.

Here is a snippet for customizing this in your user configuration:

return {
  heirline = {
    -- customize heirline colors
    colors = function(colors)
      -- make visible buffers the same background
      colors.buffer_visible_bg = colors.buffer_bg

      return colors
    end
  }
}

Switched from FiraCode to JetBrains Mono, much better thank you!

@mehalter was the italic for active tab remove? This is what i'm seeing below. Whats the easiest way of de-emphasizing the open but not currently active tab?

[mehalter]

Nope, it's still there in a base installation. You must have something in your user configuration

[mehalter]

could also be if you changed terminals and it's not properly configured with italics

[mehalter]

For debugging purposes for your config, you can use the plugin_opts utility in AstroCore to check your config:

:lua =require("astrocore").plugin_opts("astroui").status.attributes.buffer_active

[praveenperera]

::lua =require("astrocore").plugin_opts("astroui").status.attributes.buffer_active
{
  bold = true,
  fg = "buffer_active_fg",
  italic = true
}

Also italic is working in my terminal I tested, see image

@praveenperera I loaded up your configuration that it located here: https://github.com/praveenperera/dotfiles/tree/master/nvim

and I am getting italics in my terminal

[praveenperera]

thats interesting, its weird that italics works with echo. Thanks for checking, I appreciate it, I'll try and figure it out. I'm using alacrity by the way.

[praveenperera]

Figured it out at some point TERM got set to screen-256color, changed it back to xterm-256color and its working again. Thanks for your help.

[mehalter]

that will do it!
