Theme doesn't load automatically upon start up when using a lua config

[eduardo-antunes]

I'm using a lua config in the nightly build of neovim. For some reason, neovim loads the default theme instead of gruvbox8 whenever I start it up; I have to do a ":luafile ~/.config/nvim/init.lua" for it to load. I've done some testing, and this problem only happens with gruvbox8 and only when using an init.lua. Here's the line I use to set the colorscheme in my config:

vim.api.nvim_command "colors gruvbox8"

Any idea of what's going on?

(P.S.: english is not my native language, sorry if I've made some mistake)

Hi @edu-ant-vi ,
Could you try instead:

vim.cmd([[colorscheme gruvbox8]])

And see if it works?

[eduardo-antunes]

I tried it now, but the same thing happens. I believe they are actually the same function under the hood.

[jojoyuji]

how are you installing gruvbox8?
I think it is a loading order issue. I imagine you're setting the colorscheme before loading gruvbox8.

I'm using packer.nvim and this is how it is for me:

  use {
    'lifepillar/vim-gruvbox8',
    setup = function()
      vim.g.gruvbox_contrast_dark='hard'
      vim.cmd([[colorscheme gruvbox8_hard]])
    end
  }

I'm using packer too. I was setting the colorscheme after loading gruvbox8, but outside of packer.startup. I rearranged my config to do it the way you showed, but it didn't work, even after I tried reinstalling it.

Can you share your init.lua and related nvim dotfiles?

[eduardo-antunes]

Sure. My only dotfile at the moment is the init.lua:

-- Initial setup ---------------------------------------------------------------
-- vim.o for setting global options
-- vim.bo for setting buffer-scoped options
-- vim.wo for setting window-scoped options

local viml = vim.api.nvim_command    -- to execute vim commands 
local g    = vim.g                   -- a table of global variables

local scopes = {o = vim.o, b = vim.bo, w = vim.wo}

local function opt(scope, key, value)
  scopes[scope][key] = value
  if scope ~= "o" then scopes["o"][key] = value end
end

local function map(mode, lhs, rhs, opts)
  local options = {noremap = true}
  if opts then options = vim.tbl_extend("force", options, opts) end
  vim.api.nvim_set_keymap(mode, lhs, rhs, options)
end

-- Plugin declarations ---------------------------------------------------------

viml "packadd packer.nvim"

require("packer").startup(function()

  use {"wbthomason/packer.nvim", opt = true} -- packer itself

  use "lifepillar/vim-gruvbox8" -- gruvbox but faster

  use "pbrisbin/vim-colors-off" -- good ol' grey scale

  use "arcticicestudio/nord-vim" -- blue-ish, icy theme

  use  "sheerun/vim-polyglot" -- extra language support

  use  "ms-jpq/chadtree" -- file manager

  -- use  "nvim-treesitter"

  -- use "neovim/nvim-lspconfig"

  use "ryanoasis/vim-devicons" -- pretty icons

end)

I think I got the problem, somehow setting termguicolors after colorscheme gruvbox messed up the colorscheme,
try setting the colorscheme after termguicolors:

...
opt("o", "termguicolors", true)
viml "colorscheme gruvbox8"

[eduardo-antunes]

It worked, thank you very much :)
