Tabline Background Seems Corrupted

[mebaran]

I really like this plugin except I have weird white bars that make the tab bar look ugly. I'm using the Seoul256 theme for these screenshots (both with and without nerdfonts). How can I fix it? Attached images show issue.

Can you tell me the config of tabby?

[mebaran]

Here's my config for statuslines:

local function lualine_setup ()
    require('lualine').setup({
        globalstatus = true
    })
end

local function tabby_setup ()
    require('tabby.tabline').use_preset('active_wins_at_tail')
end

return {
    {
        "nvim-lualine/lualine.nvim",
        config = lualine_setup
    },
    {
        "nanozuki/tabby.nvim",
        config = tabby_setup
    }
}

I found that highlights of the theme 'Seoul256' set are not completed for tabby's separator. So the separator color is wrong. You can apply a theme object to the preset. I found a valid value by follow the lualine's theme:

require('tabby.tabline').use_preset('active_wins_at_tail', {
  theme = {
    fill = 'Visual',
    tab = 'StatusLine',
    win = 'StatusLine',
    head = 'StatusLine',
    tail = 'StatusLine',
  },
})

The preview is:

You can use :highlight command to choose what highlight you want to use. Or you can specify the color from Seoul256's color palette, for example:

require('tabby.tabline').use_preset('active_wins_at_tail', {
  theme = {
    ...
    tab = { fg = '#dfe0e0',  guibg=#545454 },
    ...
  },
})

This worked perfectly. I noticed this issue in several other themes; maybe it would make sense to make it a theme fix up option for lualine users? Now the plugin works great!

Best, Mark

I'm glad it helps.

Oh! I think this is a justifiable suggestion since the lualine looks like the most popular line plugin.

@mebaran After version v2.2.0, the user can use Lualine's theme in presets.
