Startup error: attempt to index a boolean value

[gabriel-sevecek]

Description

A clear and concise description of what the bug is.

Getting the following error on startup:

local/share/nvim/lazy/lazy.nvim/lua/lazy/core/loader.lua:438: Vim(source):E5113: Error while calling lua chunk: ...iel/.local/share/nvim/lazy/barbar.nvim/plugin/barbar.lua:18: attempt to index a boolean value 

To Reproduce

init.lua:

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)

require("lazy").setup({
    {'romgrk/barbar.nvim',
      event = "BufEnter",
      dependencies = "nvim-tree/nvim-web-devicons",
      opts = {},
    };

Informations Neovim version: 0.8.3

Can't reproduce on the latest master with the provided config (which contains a typo at the end, btw). Can you give us more details? Would you be able to run this: :lua print(vim.inspect(require'bufferline'))?

[Iron-E]

Is that the full error? If the stacktrace is longer that would help

[gabriel-sevecek]

Hey, thanks for the replies.

Running :lua print(vim.inspect(require'bufferline')) prints true.

The whole stack:

I can't reproduce either. Some things to try:

• What does :lua = require'barbar' print?
• Was the plugin successfully installed? Check lazypath in a terminal/file browser and ensure the contents of plugin/barbar.lua match the contents of the file in our repo.
• Try removing the plugin from lazypath and reinstalling it

[gabriel-sevecek]

• true
• Seems to be the same, md5sum confirms
• Tried, didn't help

I get the same error with latest neovim from master :smiling_face_with_tear:

[Iron-E]

If you can get it to repro with a minimal config like this:

nvim --clean 
     --cmd 'set rtp+=~/.local/share/nvim/site/pack/packer/start/barbar.nvim' 
     --cmd 'set rtp+=~/.local/share/nvim/site/pack/packer/start/nvim-web-devicons' 
     --cmd 'lua require"barbar".setup()'

I can probably be of more help. Otherwise, it's likely an issue on the config/lazy side

(Change the paths to wherever barbar and nvim-web-devicons are installed)

[gabriel-sevecek]

That works, no error. Seems like it's some local or lazy issue. Thanks for helping with the troubleshooting.

[gabriel-sevecek]

So, I actually had a file like this ~/.config/nvim/lua/barbar.nvim :facepalm: It contains which-key config for barbar, I guess that was being loaded instead of the actual barbar.nvim. It didn't cause any issues, until it did (I guess it stopped working after an update).

Sorry for wasting your time and thanks again.

[Iron-E]

Ah, that'd do it. Top-level modules (e.g. lua/foo.lua) that have the same name of a plugin (e.g. nvim-foo or foo.nvim) can cause clashes in the loader.

If you didn't already find another solution, you can move that file to lua/plugin/barbar.lua (or lua/<your_username>/barbar.lua) and it will work (of course, update anything that references the old path)
