Opening multiple files with -p with nightly neovim has different tabstop & expandtab values on second tab

[jthemenace]

Problem

When running on neovim nightly and nvim-treesitter is enabled, when I open 2 files using the -p command, the second tab doesn't have my configured tabstop & expandtab values from my config, however the first tab does. If I don't load nvim-treesitter it works perfectly fine.

Steps to reproduce

nvim -p file1.php file2.php
go to second tab, view settings of expandtab and tabstop
:set expandtab?
:set tabstop?

compare them with values from first tab, see that they are different

Expected behavior

I expect all tabs to have the same value from my config for expandtab & tabstop

Neovim version (nvim -v)

NVIM v0.10.0-dev-3122+ga0a189a8e

Vim (not Nvim) behaves the same?

no

How did you set these options in your config? How did you load nvim-treesitter?

[jthemenace]

In my lua config, I have the following 2 lines

vim.opt.tabstop = 2
vim.opt.expandtab = true

I use the "lazy" plugin manager. I have this line in my main plugin lua file

{'nvim-treesitter/nvim-treesitter', build = ":TSUpdate"},

Then my setup for treesitter is

require'nvim-treesitter.configs'.setup {
  ensure_installed = { "c", "lua", "vim", "vimdoc", "query", "php", "javascript", "json5", "tsx",
                       "typescript", "html", "vue", "json", "bash", "python", "diff", "markdown", "sql"},
  highlight = {
    enable = true,
    additional_vim_regex_highlighting = false,
  },
  -- indent = {
  --   enable = true
  -- }
}

Run nvim with the -V1 option and try:

:verbose set expandtab?
:verbose set tabstop?

and see where this option is set.

[jthemenace]

When I run nvim -V1 -p file1.php file2.php
when in the first tab for the first file it says
expandtab
Last set from ~/.config/nvim/lua/options.lua line 8
tabstop=2
Last set from ~/.config/nvim/lua/options.lua line 7

when in the second tab for the second file it says
noexpandtab
tabstop=8

[wookayin]

Please remember to provide full reproducible steps as instructed in the issue template. If one has to make a guess, the lines 7, 8 in ~/.config/nvim/lua/options.lua seems to be:

vim.opt.tabstop = 2
vim.opt.expandtab = true

The noexpandtab tabstop=8 config for the second tab seems to be the factory default, and I don't think this has something to do with nvim-treesitter.

[jthemenace]

In my lua config, I have the following 2 lines, for line numbers 7 & 8.

vim.opt.tabstop = 2
vim.opt.expandtab = true

This problem doesn't exist with the exact same config files and neovim version 0.9.5

[clason]

Can you reproduce this with a file containing only these two lines and nvim --clean -u test.lua ...?

[jthemenace]

when running the following with the nightly

vi -V1 -p --clean -u ~/test.lua file1.php file2.php

it works as expected, the issue isn't present

test.lua only contains the following 2 lines as suggested

vim.opt.tabstop = 2
vim.opt.expandtab = true

[clason]

Then your problem lies somewhere in your config. Add stuff to the minimal test file until you can reproduce. (The issue is usually some plugin.)

[jthemenace]

If I don't load the nvim-treesitter plugin it works fine. I tried opening a bug with nvim-treesitter and they closed it saying it can't be caused by that...

[clason]

But is nvim-treesitter the only plugin you load? What is your configuration for thst plugin? (Don't install all languages blindly.)

[jthemenace]

I use the "lazy" plugin manager and install the following plugins

return {
  {'folke/tokyonight.nvim', lazy = false, priority = 1000},
  {'neovim/nvim-lspconfig', lazy = true},
  {'nvim-treesitter/nvim-treesitter', build = ":TSUpdate"}, 
  {'lewis6991/gitsigns.nvim', lazy = true},
  {'stevearc/aerial.nvim', lazy = true},
  {'tpope/vim-fugitive', cmd = "Git", lazy = true},
  { 'nvim-lualine/lualine.nvim',
    dependencies = { 'nvim-tree/nvim-web-devicons', lazy = true }
  },
  {
    'nvim-telescope/telescope.nvim',
    dependencies = { {'nvim-lua/plenary.nvim', lazy = true} },
  },
}

My config for nvim-treesitter is

require'nvim-treesitter.configs'.setup {
  ensure_installed = { "c", "lua", "vim", "vimdoc", "query", "php", "javascript", "json5", "tsx",
                       "typescript", "html", "vue", "json", "bash", "python", "diff", "markdown", "sql"},
  highlight = {
    enable = true,
    additional_vim_regex_highlighting = false,
  },
  --indent = {
  --  enable = true
  --}
}

[clason]

Yeah, that's too many. Reduce to the absolute minimum.

[wookayin]

I tried several things based on your snippets, but I still can't reproduce the issue OP is describing, with and without nvim-treesitter. Once you manage to find a full, self-contained, clear reproduction steps based on https://github.com/neovim/neovim/blob/master/contrib/minimal.lua (please don't use lazy.nvim), please feel free to ask further help.

[jthemenace]

I tried some more things this morning to try and get it to happen on the nightly without using lazy and very minimal config, but wasn't able to get it to happen that way. I'm just going to go back to neovim 0.9.5 for now where this problem doesn't occur and hope that whatever the underlying issue is gets fixed when 0.10 gets fully released.

[clason]

Neovim 0.10 is being released right now. So keep testing.

[fczuardi]

@jthemenace have you tried adding:

vim.opt.shiftwidth = 2
vim.opt.expandtab = true

or

vim.opt.tabstop = 2
vim.opt.shiftwidth = 0
vim.opt.expandtab = true

both works for me, while:

vim.opt.tabstop = 2
vim.opt.expandtab = true

(without shiftwidth) will make the tab size be 8 spaces.

Looks like a bug to me, I am on v0.10.0

[gonzaloserrano]

I have the same or similar issue but the way to reproduce it is different. I'm on macOS, neovim 0.10.0 installed with brew and many plugins for Go dev.

So if I open 2 Go files, i.e nvim -V1 -p f1.go f1_test.go, ts is correctly set to 4 as per my ~/.config/nvim/init.lua definition of vim.opt.tabstop = 4.

But if I navigate to a different file via LSP go to definition vim.lsp.buf.definition(), the opened file has the ts set to 2 as per /opt/homebrew/Cellar/neovim/0.10.0/share/nvim/runtime/lua/editorconfig.lua.

This was not happening in neovim 0.9.5.

[jthemenace]

After this issue was closed, I opened one with lazy.nvim here

Someone mentioned it was a duplicate of this one that had the fix / answer.

I had to put my expandtab / tabstop setting(along with a few others) in my config BEFORE the lazy plugin manager is loaded. Once I did that it started working fine.
