nvim-tree feature migration

[axieax]

Hi, I'm currently migrating from nvim-tree and was wondering whether the following features are supported (feature requests if not):

• group empty directories (compact folders that only contain a single folder into one node in the file tree)
• vim.ui.input instead of popup for creating files etc. (like nvim-tree)
• netrw_hijack behaviour of open_default but for full-width window instead of the side panel (open_current replaces current, which isn't ideal)

[ ] group empty directories (compact folders that only contain a single folder into one node in the file tree)

This feature does not exist.

• vim.ui.input instead of popup for creating files etc. (like nvim-tree)

Yes, add this to your config:

  use_popups_for_input = false, -- If false, inputs will use vim.ui.input() instead of custom floats.

[x] netrw_hijack behaviour of open_default but for full-width window instead of the side panel (open_current replaces current, which isn't ideal)

If you want to open Neotree in a split, but not the current one, you can use the "open_current" behavior but use :split . and :vsplit . to open it.

Thanks for the quick response and help! For the netrw_hijack behaviour, I was more describing the following scenario:

• User opens Neovim to a directory
• neo-tree automatically opens as a full width buffer (which can be closed, unlike open_current)
• Selecting a file from the neo-tree buffer will close the buffer and open the file

Running <ctrl-w>o after loading seems to be closer to this behaviour than :split . and :vsplit ..

EDIT: I just came across the floating popup option and I love it, so I'm using that now (so no more <ctrl-w>o unfortunately)

• User opens Neovim to a directory
• neo-tree automatically opens as a full width buffer (which can be closed, unlike open_current)
• Selecting a file from the neo-tree buffer will close the buffer and open the file

Sorry but I think I am confused, what you describe above is the current behavior if you specify hijack_netrw_behavior = "open_current" and you open nvim to a directory. Does it not work that way for you?

[axieax]

open_current's behaviour is pretty much what I would like. Only thing is that when that buffer is active, it pretty much "consumes" my buffers and I cannot move to my other tabs without using my mouse for some reason. It works fine if neo-tree is opened as a separate buffer though.

In the video above you opening nvim with two buffers, one is a file and one is a dir. The strange behavior you are experiencing is due to these facts:

• You are using a plugin that displays buffers as tabs
• The buffer with a file starts out as the "active" buffer in this situation
• The hijack does not happen until you actually show the directory buffer
• Once the directory buffer is hijacked and turned into a "neo-tree" buffer, it becomes unlisted and your bufferline plugin stops showing a tab for it.

I am still confused as to why you would open a file and directory at the same time. Did you want them to open in splits like the -o option would do with two files?

[axieax]

Thanks for the followup. I guess the question is more whether it's possible to make the hijacked buffer "listed" rather than "unlisted". The main thing I want to do is navigate between my buffers after directory view is hijacked (which does not work from the video).

I am still confused as to why you would open a file and directory at the same time.

For my workflow, I like to open nvim with the files/directories which I will be working on, then further selecting the files within directories to open (eliminates the need to find and search for the subfiles). In this case, I would like the directory listing to be treated as an "active" buffer (like for a normal file opened to the full-width of the editor). Sorry for the confusion!

[cseickel]

OK, in that case all you need is the ability to override the local options with a setlocal buflisted. This is related to #155.

[axieax]

Oo I just tried adding vim.cmd("au! FileType neo-tree setlocal buflisted"), and it seems like the buffer becomes active before quickly becoming inactive again (and opened files disappear from the buffer line as well - which seems to be a normal issue regardless of autocmd). I am doing this incorrectly lol.

Because I use my own event system, the timing can be a little off. This will work around that:

autocmd Filetype neo-tree lua vim.schedule(function() vim.cmd("setlocal buflisted") end)

[axieax]

Works perfectly now. Thank you so much for the followup help!

@cseickel apologies for hijacking the issue, but it seems like it's related to latest discussion here.

I have following autocmds set for nvim-tree:

vim.api.nvim_create_autocmd({ 'WinEnter', 'BufWinEnter' }, {
  pattern = 'NvimTree_*',
  callback = function()
    vim.api.nvim_command 'highlight! Cursor blend=100'
    vim.opt.guicursor = { 'n:Cursor/lCursor', 'v-c-sm:block', 'i-ci-ve:ver25', 'r-cr-o:hor2' }
  end,
})

vim.api.nvim_create_autocmd({ 'BufLeave', 'WinClosed' },{
  pattern = 'NvimTree_*',
  callback = function()
    vim.api.nvim_command 'highlight! Cursor blend=NONE'
    vim.opt.guicursor = { 'n-v-c-sm:block', 'i-ci-ve:ver25', 'r-cr-o:hor20' }
  end,
})

I tried to replicate the same for neo-tree by changing pattern to neo-tree but it does not seem to be working at all, no events get triggered. Do you know what I am doing wrong here maybe?
(this is to hide cursor in tree views and restore it after leaving tree's window)

[cseickel]

I think you may have a timing issue @gegoune. I'm not sure the name is applied before those events fire.

I think it will be faster for me to just do #155 than to work this out. I'll do that tonight.

[cseickel]

@gegoune, see #155 (comment)

That code is in main right now, I will probably release it to 2.x tomorrow.

[gegoune]

@cseickel Perfect, that's working as expected now, thanks!

[cseickel]

@axieax I just added the group empty directories option: #216
