Getting an error after adding new item to quicklist and then opening another item

[fent]

Hi! I'm getting the following error after I add an item to the quicklist using the default <leader>qq mapping. Afterwards, if I navigate to the quicklist and hit on another item I get this error:

Error detected while processing BufEnter Autocommands for "<buffer=14>":

If I navigate to another quicklist item using :cnext or :cprevious I get another error

I'm also getting a glitched looking buffer of the file afterwards, with "Quickfix Note" appended to the lines that were previously in the quickfix list but not added through this plugin

So I think it's getting confused with items that were already there

[arsham]

Thanks for raising this issue.

May I ask what version of Neovim you are using?

When you produce the glitch, is there any Zs in the qf buffer? Those items indicate which entry is created by the user. This is an example:

Basically, this plugin should not add any extmarks/signs for anything that don't have a Z in there.

Can you provide a minimal config with step by step process to produce these errors please?

neovim version: v0.9.0

to reproduce:

• save the following as repro.lua

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/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", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  -- add any other plugins here
  {
    "arsham/listish.nvim",
    dependencies = {
      "arsham/arshlib.nvim",
      -- "nvim-treesitter/nvim-treesitter-textobjects",
    },
    ft = "qf",
    opts = true,
  },
  {
    "nvim-telescope/telescope.nvim",
    dependencies = { "nvim-lua/plenary.nvim" },
    keys = {
      { "<C-p>", "<cmd>lua require('telescope.builtin').live_grep()<cr>" },
    },
  },
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

• run nvim -u repro.lua
• press <ctrl-p> to open telescope search
• search for something that shows some results
• press <ctrl-q> to place results in qflist
• select first result
• move the cursor to another line and press \qq to add it to the qflist
• focus the qflist
• select another item
• see error

I'm afraid I couldn't find the root cause of this bug. My guess is that the Telescope does something with the buffer that is not supposed to, but I can't be sure.
I've done many tests with FZF and Telescope, everytime FZF works but the Telescope doesn't.

[fent]

maybe they populate the qflist in slightly different formats?

[arsham]

I don't think it is possible. The setqflist has a very specific set of input.
