2 statuslines

[7ijme]

Describe the bug

Yeah i don't know why but this happens

this is my lualine config

require("lualine").setup({
	options = {
		theme = "onedark",
	},
	sections = {
		lualine_a = { "mode" },
		lualine_b = { "branch", "diff", "diagnostics" },
		lualine_c = { "filename" },
		lualine_x = { "filetype" },
		lualine_y = { "location", "progress" },
		lualine_z = { "os.date('!%H:%M:%S', os.time()+get_timezone())" },
	},
})

To reproduce

I just installed this and have lualine configured

Expected behavior

Just 1 statusline

Terminal emulator

Windows Terminal > wsl

You can blame lualine for this, they are unconditionally setting laststatus=2, unless their useless globalstatus option is enabled: https://github.com/nvim-lualine/lualine.nvim/blob/84ffb80e452d95e2c46fa29a98ea11a240f7843e/lua/lualine.lua#L521

This is not only absolutely ridiculous, the entire lualine globalstatus option is a clown fiesta in and of itself, because it just replicates the laststatus option without adding any benefit (also read #24 (comment)).

As a workaround for now you can put au VimEnter * set laststatus=0 in your config to overwrite lualine's ridiculous behaviour.

But let me check if I can add a workaround from this plugin side so that it works without any user config...

In general though, I don't recommend using lualine, the maintainer has repeatedly shown being unaware of following any basic vim idiomatic patterns (see also #51 (comment) or #50 (comment) or grep the git log for the kind of workarounds that lualine needs).

Edit: Fixed this now.

I ran into this issue too, here's my solution when using LazyVim.

Tried but didn't work

-- ~/.config/nvim/lua/config/autocmds.lua
vim.api.nvim_create_autocmd("VimEnter", {
  callback = function()
    vim.opt.laststatus = 0
  end,
})

-- ~/.config/nvim/lua/config/options.lua
local opt = vim.opt
opt.laststatus = 0

What works for me

-- ~/.config/nvim/lua/plugins/ui.lua
return  {
    "nvim-lualine/lualine.nvim",
    config = function(_, opts)
      require("lualine").setup(opts)
      vim.opt.laststatus = 0
    end,
  }

For some reason none of the above (autocmd, init option, simple callback, etc) worked for me and there were 2 lines always.

The following adjustment always works:

config = function()
  require('lualine').setup({
    .......
  })

  if os.getenv('TMUX') then
    vim.defer_fn(function() vim.o.laststatus=0 end, 0)
  end
end

Plus tmux check, so works with or w/o tmux.

You need to make sure that the autocmd runs after lualine's own autocmds (which create the problem in the first place). Furthermore, lazy.nvim's lazy loading may interfere even further, use a proper plugin manager. This plugin already uses Vim's native autoload mechanism for lazy loading.

This worked for me, lualine is such a bitch to work with

@hashem78 actually above solution is not a proper one ^^^ because the problem is not only lualine, but (in my case) a lualine+tpipeline+lazy.nvim combo. Actually, to all work correctly, one should ensure following sequence of events:

1. lualine is loaded first
2. lualine have cycles in interpreter to run its lua code and setup everything
3. tpipeline is initialized after p1 AND p2
4. possibly do p1-3 before UIEnter to avoid blinking

To test if everything is correctly initialized do :autocmd ModeChanged. Tpipeline hooks need to be after Lualine hooks. If they are the opposite, all works weirdly.

So the problem is how to ensure this with your package manager (I can say only about lazy.nvim).

Below is the config I use lately:

local function init()
  vim.g.tpipeline_autoembed = 0
  vim.fn.jobstart('~/bin/mytmuxstatusline', { detach = true })

  -- disable statusline in horizontal splits
  -- https://github.com/vimpostor/vim-tpipeline/issues/19
  vim.g.tpipeline_clearstl = 1

  -- fix lualine+tpipeline+lazy combo
  vim.defer_fn(function()
    local autocmds = vim.api.nvim_get_autocmds({ event = "ModeChanged" })
    if autocmds[#autocmds].group_name == 'tpipeline' then return end

    vim.api.nvim_del_augroup_by_name('tpipeline')
    vim.g.tpipeline_statusline = '' -- because tpipeline_clearstl=1
    vim.call('tpipeline#build_hooks')
  end, 0)
end

return {
  {
    'vimpostor/vim-tpipeline',
    init = init,
    dependencies = 'nvim-lualine/lualine.nvim',
  }
}

1. it ensures p1 via dependencies
2. it ensures p2 via defer_fn
3. it fixes ModeChanged hooks order (in a hacky way, but 🤷‍♂️ works for me and simple)

That's best way I have come so far.

Alternative way for lazy.nvim is to do:

{ 'vimpostor/vim-tpipeline', event = 'VeryLazy' }

Which just forces to load tpipeline after all plugins are loaded and VimEnter. But it creates some flickering on startup (p4) because it is after VimEnter, so it draws one UI, and then quickly another UI, which results in brief blink.

I don't say that those are "idiomatically correct" fixes, and maybe they can be improved, but the problem is exactly what I said in the begining, so any other solution that addresses it will also work.

Feel free to use.
