Add file tree

[gbaranski]

What do you think about that? It's quite useful when you know visually where a file is, but not name of the file.

Same feature in neovim using nvim-tree.lua

[gbaranski]

If you're interested in having this feature, I can try to implement this and open a pull request.

I prefer the fuzzy searcher myself, if you know some of the subdirs, you can still find it fairly easily

I like making a lot of files and folders, that makes it easier to navigate with file tree, and I can open folders that I'm currently working on, without being distracted by other folders that I'm not currently interested in. With fzf I see all files, even those which I am not working on currently.

[archseer]

I think this would be best suited as a plugin, though it can probably start as a subcrate until the framework is in place, that way it can at least be compiled separately and disabled via a flag. It's quite a lot of extra UI work though.

Personally I also use a fuzzy searcher or use nnn or zsh + exa externally to do that type of stuff. I did admire vim-dirvish for doing it with text buffers as a different approach.

[gbaranski]

In my opinion it would be better as a built-in feature, just like Vim has netrw, vscode/atom/intellij has built-in file tree

[pickfire]

I wouldn't use it personally but if someone could come up with a good idea based on existing file tree like netrw or dired in emacs which could be better than them I don't see why we can't bundle it.

One issue with file tree or these kind of stuff is that I can never remember the key, with the kakoune popup help box at the bottom right maybe we can get this right.

In Vim I use C-t for toggling the file tree. AFAIK helix doesn't have buffers and navigation, so the question is how to implement moving cursor between file tree and main buffer?
C-t could toggle file tree if it's not opened yet and cursor is in main buffer, if it's already open it can just move cursor to it. And if cursor is inside file tree C-t would move cursor to the main buffer.

[pickfire]

I think helix have something similar to buffer since you can pick and open another file but maybe we don't have buffer yet. We probably need to create another issue for this.

[archseer]

AFAIK helix doesn't have buffers

We do have buffers (and views/splits), <space>b opens a "open buffers" list. There's currently no way to close a buffer though, :q only closes the split.

[cessen]

Just tossing in my two cents. This is what I said on matrix:

[...] personally I'd rather keep a side-panel tree view out of Helix. But I think the use-case it solves is important to address, so maybe there are other ways to tackle it.

One possibility would be an alternative file finder to the one currently on f, where it acts as a tree-based file navigator. That way it comes up on demand when you're looking for a file, rather than being a persistent element of the UI.

And a little later:

But I do miss having a tree-based navigation system. Not as a replacement for fuzzy search, but as a supplement. It's really useful for e.g. exploring an unfamiliar code base, especially.

[Omnikar]

I would love this feature

I once looking at Taupiqueur's dotfiles and found him using sidetree.

_{I personally just open up a terminal to the side and cd/ls around, not even using a file manager.}

[Robert-M-Muench]

https://github.com/Canop/broot might be a good inspiration, or even using the code base.

I would prefer such a feature as built into HX, and not configured separately. Makes things much simpler to install.

[stoeckley]

I like nerd tree in vim, and have it bound to a simple keystroke that pops it open along the side, and the same keystroke to hide it. It’s great for jumping back-and-forth, opening, viewing folder structure and finding files. It’s a fundamental part of how I approach editing and understanding any project, and the vim implementation does not get in the way.

I started using helix today, and read through the documentation twice looking for this feature, as it is a basic tool that any editor should have - I’ve never used an IDE without one easily available either natively or as a plug-in. I will admit I was very surprised to discover there is no such feature. I add my vote that it’s a fundamental IDE tool.

Most of the people uses nvim-tree.lua instead of nerdtree nowadays

https://github.com/kyazdani42/nvim-tree.lua

[xialvjun]

I just want to mention that maybe we should use alphabetical order rather than last access time order in file tree.

I like the idea sidetree work with kakoune, let other program commuicate with the editor, not write all code by the edtior itsefl.

https://github.com/cossonfork/helix/tree/tree_explore

[lukepighetti]

I am looking for this feature, but perhaps we could consider this as a general tree display / navigation / search feature. A file explorer could be the first implementation of this.

Trees show up in all types of development, for example, the Flutter tooling allows you to dump the widget tree for display in an IDE (or perhaps in a general solution helix tree viewing tool). These IDE tools are notoriously slow to load, and very difficult to traverse... but if we could find a nice way to traverse complex trees in a way that is fast and handles large trees, especially with search and ID based markers, that would be immensely useful even outside of showing files.

You can see it here on the left: https://docs.flutter.dev/development/tools/devtools/inspector#flex-layouts These trees often get massive and I have yet to see a tool handle it well.

Possible operations:

• fuzzy find item in tree by name
• add item to buffers/jumplist
• open item in split
• go to parent
• go to last selected child (or first)
• go to next item tagged with diagnostic
• expand/collapse item
• expand/collapse all children recursively

[qkzk]

The lack of this feature is what prevents me from switching from neovim + a ton of plugins to helix.
I'd rather have a bloated config as fast as it's buggy than not being able to explore the tree directly from the editor.

[erlangparasu]

i hope Helix implements built-in file explorer like vscode (File Explorer, Search, and Git too) 🙏

[daanvdk]

Another use case of a file explorer that I do not see mentioned yet in this discussion is that it is also a neat place to do other file operations than just opening files (compared to fuzzy finding) like creating/deleting/renaming/moving files. This is what I mainly use https://github.com/nvim-telescope/telescope-file-browser.nvim for opposed to fuzzy finding in my current neovim setup.

[rvdende]

Just a note here for future noobs like I was.
There is a built in file picker (not quite like the file tree, but it works).
Press space f

[tristonarmstrong]

the fuzzy search doesn't work well for me unfortunately, due to the fact that i, for the life of me, cannot remember every directory/filename. With hundreds of files i think thats pretty reasonable.. I relied on the :E command in neovim... Im probably just garbage, but yuh know.

[heyakyra]

Lapce is apparently the spiritual successor to Xi editor, has this feature, and has a puplar ticket for Helix-style controls: lapce/lapce#281

[archseer]

Okay, but Lapce isn't Helix. This is the Helix issue tracker.

[goyalyashpal]

use nnn or zsh + exa externally to do that type of stuff
- @ archseer at #200 (comment)

can u share screenrecord?

[goyalyashpal]

With fzf I see all files, even those which I am not working on currently.
- @ gbaranski (author) at #200 (comment)

is this the problem, or if the suggested feature of a separate file tree view exactly what u want??

as in, would it help u if the current fuzzy finder¹ itself supports collapsable tree view with indentation for subdir contents?
Edit: this same view is shared by @ cessen at #200 (comment)

Footnotes

1. that popup which opens when u press Space f for open file picker right?
   Edit: i think fuzzy finder is different - i don't know what it is then ↩

Personally I also use a fuzzy searcher or use nnn or zsh + exa externally to do that type of stuff. I did admire vim-dirvish for doing it with text buffers as a different approach.

@archseer can you elaborate on how you do your workflow with nnn? for example, how do you quickly go from a file that you have open in helix to navigating it's directory?

[lukepighetti]

Anyone know if it's possible to get a program like nnn to make an existing instance of hx open a file? If so, maybe the answer here is to compose our environments in something like zellij

[goyalyashpal]

You could take a look at this action inside zellij https://zellij.dev/documentation/cli-actions.html#write
But at this point this is more like a hack and would probably break easily.

But I think at this point this is outside the subject of the issue.

[espositofulvio]

Hello Everyone,
I've just started using Helix and it's the first time I'm actually managing to adapt to modal editing, I find it very intuitive. I've come up with this issue as I'm also interested in this kind of project view, filepicker is awesome but sometimes a tree view fits better. Unfortunately I am not very fluent in rust (just learning) so I'm not to the point I can contribute, but if it can be of help I'm also using gitui which has a crate for a file treeview (https://github.com/extrawurst/gitui/tree/master/filetreelist) available. I'm not sure if Helix will implement this (I do hope so) but maybe it can be at least of inspiration.

[qkzk]

Hello !

Is there a way to communicate with a running Helix instance and pass commands from outside ?

RPC, stdin, whatever ?
I know there's no plugins so this option is out.

There's many TUI file managers written in rust, we could simply use another crate and communicate.
It would be much simpler than integrating a new filemanager from scratch in Helix.

Something like this should do the trick:

1. open Helix
2. open a terminal with the FM from Helix
3. select the desired file in the FM
4. send a command back to Helix from the FM (which requires to modify the FM in some way)
5. close the term

[goyalyashpal]

2. open a terminal with the FM from Helix

how to "open a terminal from helix" ?

[qkzk]

Yes, ATM you can't:/

[calebebteixeira]

Oh yeah, I feel like once we have a file tree feature on Helix, it will have a lot of adoption. I feel like this is the only thing that's preventing me from switching from Neovim. Great job guys!

I would switch in a hart beat.. loving helix, but really miss a file tree..

[dead10ck]

Hey guys, I'm just going to reiterate @archseer's point: it is not helpful to make comments like "this is the only thing keeping me from switching". There is already an open PR (#5768). The problem is not that we need convincing that it is important, it is that the maintainers need time to review the PR in our spare time. I'm going to lock the conversation since there isn't really much meaningful discussion left to have around the issue itself.
