Tabby no-nerd-font config with Nord theme

[VKondakoff]

Hi!

Just wanted to share my slight modification of 'no-nerd-font' example used with Nord theme.

Explanations:

• I have added window count in square brackets to the tabs. So, the active tab has 4 windows, not active tab has 2 windows
• Each buffer has it's buffer number before the name and modification status after the name. So the active buffer 3 is dirty.

Here is the code:

require('tabby').setup()
local filename = require('tabby.filename')
local util = require('tabby.util')

local hl_tabline = util.extract_nvim_hl('TabLine')
local hl_tabline_sel = util.extract_nvim_hl('TabLineSel')

---@type TabbyTablineOpt
local tabline = {
  hl = 'TabLineFill',
  layout = 'active_wins_at_tail',
  active_tab = {
    label = function(tabid)
      return {
        '  ' .. vim.api.nvim_tabpage_get_number(tabid) .. ' [' .. table.getn(vim.api.nvim_tabpage_list_wins(tabid)) .. '] ',
        hl = { fg = hl_tabline.fg, bg = hl_tabline.bg, style = 'bold' },
      }
    end,
    right_sep = { ' ', hl = 'TabLineFill' },
  },
  inactive_tab = {
    label = function(tabid)
      return {
        '  ' .. vim.api.nvim_tabpage_get_number(tabid) .. ' [' .. table.getn(vim.api.nvim_tabpage_list_wins(tabid)) .. '] ',
        hl = { fg = hl_tabline_sel.fg, bg = hl_tabline_sel.bg, style = 'bold' },
      }
    end,
    right_sep = { ' ', hl = 'TabLineFill' },
  },
  top_win = {
    label = function(winid)
      return {
        ' > ' .. vim.api.nvim_win_get_buf(winid) .. ': ' .. filename.unique(winid) .. ' ' .. (vim.api.nvim_buf_get_option(vim.api.nvim_win_get_buf(winid), "modified") and '[+]' or ''),
        hl = { fg = hl_tabline.fg, bg = hl_tabline.bg, style = 'bold' },
      }
    end,
    left_sep = { ' ', hl = 'TabLineFill' },
  },
  win = {
    label = function(winid)
      return {
        ' - ' .. vim.api.nvim_win_get_buf(winid) .. ': ' .. filename.unique(winid) .. ' ' .. (vim.api.nvim_buf_get_option(vim.api.nvim_win_get_buf(winid), "modified") and '[+]' or ''),
        hl = { fg = hl_tabline_sel.fg, bg = hl_tabline_sel.bg },
      }
    end,
    left_sep = { ' ', hl = 'TabLineFill' },
  },
}

require('tabby').setup({
  tabline = tabline,
})
