Error when generating CMake files.

[carlosdr02]

Description

I get an error when generating the CMake files through this plugin:

I have started to use nvim-tree very recently so I don't know much about it, but I think this happens because after generating the CMake files, nvim-tree tries to reload itself and something goes wrong.

I've also opened an issue in the CMake plugin github page and the author told me: "Not sure why, but looks like its nvim-tree tries to reload after adding things to quickfix."

Although I've included my config and the steps to reproduce, I think developers of this plugin might just be able to tell what the problem is by just looking at the error message. The only thing I can think of is maybe set "auto_reload_on_write" to false, but that would also mean that git changes would not show in the tree when I save my files, am I wrong?

Neovim version

NVIM v0.8.1

Operating system and version

Windows 11

nvim-tree version

e0cfbbb

Minimal config

require('packer').startup(function(use)
	use 'wbthomason/packer.nvim'
        use {
            'nvim-tree/nvim-tree.lua',
            requires = {
                'nvim-tree/nvim-web-devicons',
            },
            tag = 'nightly'
        }
        use 'Shatur/neovim-tasks'
end)

require('nvim-tree').setup()

local Path = require('plenary.path')
require('tasks').setup({
    default_params = {
    cmake = {
        cmd = 'cmake',
        build_dir = tostring(Path:new('{cwd}', 'build', '{os}-{build_type}')),
        build_type = 'Debug',
        dap_name = 'lldb',
        args = {
        configure = { '-D', 'CMAKE_EXPORT_COMPILE_COMMANDS=1', '-G', 'Ninja' },
    },
},
  },
  save_before_run = true,
  params_file = 'neovim.json',
  quickfix = {
      pos = 'botright',
      height = 12,
  },
  dap_open_command = function() return require('dap').repl.open() end,
})

Steps to reproduce

1. On the root folder (where the CMakeLists.txt file is located) of a CMake project, run :Task start cmake configure to generate the CMake files.
2. Select the build target (e.i., the executable) by running :Task set_module_param cmake target.
3. Finally, build and run the project by running :Task start cmake run.
4. You should see the same error you saw on the image posted above.

Expected behavior

No response

Thank you for raising. We do indeed refresh on quickfix window open. Happening since c5dc80c when filters.no_buffer enabled. Also occurs with 18272f8 when highlight_opened_files set.

#1830 will partially address this issue.

@chomosuke I'd appreciate your thoughts.

It seems that we are responding to way too many unnecessary BufReadPost events.

Possibility: do nothing unless vim.fn.filereadable

I'd be grateful if you could test the fix on latest master.
