Help: could not install Tabby properly

[VKondakoff]

Hi!

I'm trying to install Tabby using the instructions (macOS, iTerm2, Neovim nightly, Packer).
Here is what I see after running :PackerInstall and :PackerCompile:

And here is what I see after restarting Neovim:

What am I doing wrong? (Quite a newbie here.)
Thanks!

In the first image, the nerd font does not display correctly. You need a nerd font patched font: https://github.com/ryanoasis/nerd-fonts

In the second image, something may be wrong. Can you type command :messages and see there is some error message?

Hi, nanozuki, thanks for helping me!

Second image: this just happens after restarting Neovim - for some reason Tabby is not shown after restart. No error messages are shown. Here is a short video:

require('packer').startup(function()
  use 'wbthomason/packer.nvim' -- Packer can manage itself
  use {
    "nanozuki/tabby.nvim",
    requires = "kyazdani42/nvim-web-devicons",
    config = function() require("tabby").setup() end,
  }
end)

Is this code enough to show Tabby or I should explicitly call it somewhere else?

Are you able to reproduce the issue with a minimal_init.lua file? Try running the minimal setup below and see if you are still having issues. Also note in the file I am making sure that a colorscheme is applied before tabby's setup function.

-- Open with `nvim --clean -u minimal_init.lua`
local install_path = "/tmp/nvim/site/pack/packer/start/packer.nvim"
local compile_path = install_path .. "/plugin/packer_compiled.lua"
vim.opt.packpath = "/tmp/nvim/site"

local function load_plugins()
  local packer = require("packer")
  local use = packer.use
  packer.reset()
  packer.init({ compile_path = compile_path, package_root = "/tmp/nvim/site/pack" })

  use("wbthomason/packer.nvim")
  use({
    "edeneast/nightfox.nvim", -- Adding some sort of colorscheme
    config = function()
      vim.cmd("colorscheme nightfox")
    end,
  })
  use({
    "nanozuki/tabby.nvim",
    requires = "kyazdani42/nvim-web-devicons",
    after = "nightfox.nvim",
    config = function()
      require("tabby").setup()
    end,
  })
  packer.sync()
end

_G.load_config = function() end

if vim.fn.isdirectory(install_path) == 0 then
  vim.fn.system({ "git", "clone", "--depth=1", "https://github.com/wbthomason/packer.nvim", install_path })
end
load_plugins()
vim.cmd([[autocmd User PackerComplete ++once echo "Ready!" | lua load_config()]])

Hey, that's it! @EdenEast, thanks for pointing me.
lightline.vim is causing the issue.
Tabby shows up if I comment the following code:

use {
   'itchyny/lightline.vim',
   config = function()
     vim.g.lightline = { --Set statusline
     colorscheme = 'nord',
   }
 end,
} -- Fancier statusline

@nanozuki, is Tabby not compatible with statusline plugins?

[EdenEast]

I know it works with statuslines like feline.nvim and lualine (current maintained fork). Looking at lightline it looks like it does the tabline as well. They are conflicting.

[nanozuki]

In nvim, the tabline is a global option. So you can only use set one tabline, and two tabline plugins will conflict. I read the lightline.vim, it seems that it can't only close the tabline, so it can't use with tabby.nvim. You can ask the author to provide an option to only provide a statusline.

Hi @VKondakoff , I know this is an old issue, but here I go,

You can disable the tabline feature of lightline.vim with the following code:

vim.g.lighline = {
  ...other_options,
  enable = { tabline = 0 },
}
