Nvim-tree version master branch

Describe the bug Every time I try to open nvim-tree this error show. and no icon, files and folder show.

To Reproduce Use any nvim-tree command example NvimTreeRefresh, NvimTreeOpen

Expected behavior Nvim Tree should be open without any error

[sebastianbock17]

+1 I have exactly the same issue!

[kyazdani42]

cannot reproduce this, do you have newlines in your filenames ?

[sebastianbock17]

The fastest method for reproduction is e.g. just installing lunarvim, I deleted all the configs (from .local/share and .config), and I get the error directly upon start now. Its strange since it only happened since this morning …

Error executing vim.schedule lua callback: ...cker/start/nvim-tree.lua/lua/nvim-tree/renderer/init.lua:397: String cannot contain newlines
stack traceback:
        [C]: in function 'nvim_buf_set_lines'
        ...cker/start/nvim-tree.lua/lua/nvim-tree/renderer/init.lua:397: in function 'draw'

        vim.lua:285: in function <vim.lua:285>

So in line 397 is the following:

  api.nvim_buf_set_lines(view.View.bufnr, 0, -1, false, lines)

The checkhealth does not even have nvim-tree mentioned and it all seems alright.

One strange thing though, is that I can not access any folder for my user (e.g. /home/test/)

But, I can activate nvim-tree and open folders that are on my usb stick - thats really strange.. I hope a solution can be found, I can (sort of) live with that in the moment, but now I can't navigate on my .config folder with nvim-tree …

@kyazdani42 The message comes without even opening a specific file, just running nvim / lvim in a folder which is in any home directory produces this error, regardless of the contents from files. When I start from a directory in a external harddrive, it works.

Another Edit and a hint:

When I use :Lexplore, then focus on lvim pane right, and when I then refocus the pane on the left from :Lexplore, the window becomes nvim-tree instead :Lexplore - but under one condition - it works only, if I navigated into a specific folder with :Lexplore. The default folder for :lexplore is just the /home/user directory.

So if I navigate into the ~/.config/nvim/ directory with :Lexplore, then focus the nvim buffer on the right, then refocus the :Lexplore buffer, it transforms into nvim-tree with its icons and functions. After this, I can close and also reopen the nvim-tree buffer again.

So with this workaround, nvim-tree still works for a session. So it has to do with setting a current working directory maybe? I hope someone else with better knowledge can reproduce, must be a bug somehow.

Any solutions found @meanindra ?

[sebastianbock17]

For me it's working again, don't really know what caused the issue. It worked since I deleted the compiled file from packer in plugin folder, running :PackerCompile, :PackerSync, and :Packer Update

It's strange because I had tried it before, but now it works again like a charm!

[kyazdani42]

might be an issue with the lunarvim config maybe ? i'm not sure. Or maybe conflicting with another plugin.

[alex-courtis]

@meanindra perhaps you could provide a reproducible test case:

Start with the minimal config as per the bug report template: https://github.com/kyazdani42/nvim-tree.lua/issues/new/choose

Add your nvim-tree config. If you still cannot reproduce, add your plugins and their configuration until you can reproduce.

Post that modified minimal config and we can attempt to reproduce that.

[zamboney]

I had the same problem and (after i reinstall neovim and nvim-tree) the issue didn't solve!

finally i figure out the problem. it's seem that i had one file the contain newline in it.

so in order to reproduce this issue all you need to do is create a file that contain a newline and the error thrown.

example:

touch file$'\n'

hope it's will help 😄

[kyazdani42]

is it even a good idea for a filename to contain newlines :smile: ? I guess we shouldn't crash though, but still it's a bit weird.

[alex-courtis]

Closing due to inactivity.

[Oumar-1]

i have the same error but i have fixed by just commenting ignore_list at update_focued_file

i don't why it works but it does update_focused_file = { enable = true, update_cwd = true, --[[ ignore_list = { "/node_modules" }, ]] },

[Samgarr]

Hello, i m also experiencing this issue. I can confirm that crash is cause by newline in file name. In my case, file with newline in name was created by mistake and i am convinced that it should not lead to crash of nvim-tree.

Replicated with touch foo$'\n'bar

[alex-courtis]

This should be resolved - displaying, opening and renaming files.

I'd be grateful if you tested a fix @Samgarr

cd /path/to/nvim-tree.lua
git pull
git checkout 925-handle-newlines-in-file-names

When you're finished testing:

git checkout master

[alex-courtis]

@Samgarr I'd be grateful for your testing this, as it's operating system dependent.

[Samgarr]

Sorry for late response, i didn't notice the notification. I can confirm that the fix works for me.
