lambdalisue / fern.vim Goto Github PK

A temporary buffer (e.g. fern:///file:///Users/alisue) remains in buffer list.

1. Open Vim
2. :Fern .
3. :ls!

  1u%a-  "fern://84dc699d/file:///Users/alisue$" line 1
  2u     "fern:///file:///Users/alisue;$" line 1

Let me start by thanking you for this. I've been looking for a faster and more lightweight alternative to NERDTree for a while now and I'm very glad that I found your plugin. It seems to be able to combine everything I liked from existing file explorers out there.

Now, I’m looking for something similar to NERDTree’s NERDTreeFind command. I’d really appreciate if you could add this functionality as well. That’s one of my main usages currently with NERDTree (quickly see where a file is located within the dir hierarchy and which other files are its siblings).

It would be also great if you added some documentation as well. So far I was able to understand a lot from reading the code (e.g.: available actions, how to override mappings), but documentation definitely helps.

I can't perform a backward search because the plugin show the actions help. Is there some way to change that behavior?

vim-fugitive uses the g? to avoid this conflict. I think it'd be a good alternative.

Thanks.

:Fern / displays fern://xxxxxx/:/// but fern://xxxxx/file:/// was expected.

From. #36

It seems open:select action does not work on Vim but Neovim.

:Fern . -drawer
select LICENSE -> a -> open:side
select README -> a -> open:side
a -> open:select

Vim

Neovim

While a helper instance which will be returend from fern#helper#new() is a public API, I would love to test all features.

I'm at my home dir ~, editing file ~/fern/info.txt

Tried to use one of the following commands, none of them works

Fern . -reveal=%
Fern %:h -reveal=%
Fern %:p:h -reveal=%

I got this error fern: {base} ("Users/phong/fern") must be an absolute path.

I'm using vim 8.2 and latest fern.vim, please check details here: https://asciinema.org/a/9oVxreInZhp3MnsCyvD6nOsVa

Steps to reproduce:

:Fern . -drawer
:e anyfile

Actual behavior:
anyfile opened in Fern drawer split.

Expected behavior:
anyfile opened in other split

Screenshot:

If an expanded node has removed by trash/remove action of file scheme, the node remains (displayed) even after redraw.

Now :e fern:///file:///C:/ works correct but :Fern C:¥ so might be some changes are conflicted with #68 ?

Prior to v1.0, 1) move out from internal which should be public (used by 3rd parties), 2) move into internal APIs which should be private

When I choose some file and in that file I press to alternate <c-^>`, the fern buffer takes place.

Is this some way to change that behavior and after I choose some file in the fern, the fern buffer wipe out itself, so I can't alternate to the previous file before I had opened the fern?

It's nice if file scheme support terminal action or whatever to open a terminal on a cursor node.

May I use floating window or popup for this?

Internally, System.Filepath vital module is used but

• It has more features than I needed
• It has fewer features than I needed
• It has non pure functions (we need to test features on Linux or Windows)
• It does not handle C: well (#69)

So make a more suitable one for fern's file scheme.

Workaround is :Fern . -drawer | sleep 1m | execute "normal! \<C-w>\<C-p>" but it's a bit ugly.
It would be nice if user can execute

:Fern . -drawer -stay

To open a fern drawer without moving focus.

Now fern.vim does not have any CI and I'd like to use Github action to perform tests but I could not be bothered to do for now...

What you need to execute is a command themis from thinca/vim-themis if you are interested in to help this issue 👍

It seems open:select action does not work when the action has invoked through the action prompt.

When rename, most of time users want to rename it's filename but path so move cursor on filename rather than [0, 0]

便利なプラグインをありがとうございます。
いくつか機能要望と質問と不具合報告をさせてください。

不具合報告

1. Fern / が正しく動作しない？
   /etc や /usr などが表示されることを期待していましたが、適切に表示できない気がします。

機能要望

1. autoload/fern.vim あたりに利用者向けの API があると嬉しいです。
   例えば、カーソル上のノードを取得したり、現在表示中のルートパスを取得したり、cd したりなどです。（file provider 以外の場合にこまる可能性がないとも言えないので、あくまでも要望として）

質問

1. 表示中に Fern バッファのルートパスを変更する正しい方法は Fern %path% をバッファ上で叩くで正しいでしょうか？

Hi, thanks for the plugin. I've been finding a good alternative for the NERDTree and I think I have found it. :)

Is there some way to open all the selected nodes? I don't find anything in the readme neither in the ?.

I'm a novice at vim. I like your plug-in very much. It's lightweight, fast and powerful compared to nerdtree. But can you add exit commands, such as nerdtree, which starts the first time and exits the second time? I believe this experience will be better! I think justinmk / vim-dirvish plug-in has some good functions, such as K output file details, can you learn from it? Sorry, my English is not very good.

ref: https://github.com/lambdalisue/fern.vim/wiki/Tips#use-fern-as-a-default-directory-browser-hijack-netrw

My vimrc:

  function! s:hijack_directory() abort
    if !isdirectory(expand('%')) || &ft == 'fern'
      return
    endif
    Fern %
  endfunction
  function! s:plug.after.lambdalisue__fern()
    " hijack netrw
    let g:loaded_netrw             = 1
    let g:loaded_netrwPlugin       = 1
    let g:loaded_netrwSettings     = 1
    let g:loaded_netrwFileHandlers = 1
    augroup my-fern-hijack
      autocmd!
      autocmd BufEnter * ++nested call s:hijack_directory()
    augroup END
  endfunction

I tried:

:buffers!
  1 #h   "."                            line 1
  2u%a-  "fern://87b06d06/file:///Users/kyoh86$" line 1
  3u     "fern:///file:///Users/kyoh86;$" line 1
:bw
:buffers!
  1 #h   "."                            line 1
  3u%a-  "fern://cdb7d1ac/file:///Users/kyoh86$" line 1
  5u     "fern:///file:///Users/kyoh86;$" line 1

fern://... buffer is still alive.

Maybe a buffer should be wiped out (bwipeout %) before calling Fern:

  function! s:hijack_directory() abort
    let l:target=expand('%')
    if !isdirectory(l:target) || &ft == 'fern'
      return
    endif
    bwipeout %
    execute 'Fern ' . l:target
  endfunction
  function! s:plug.after.lambdalisue__fern()
    " hijack netrw
    let g:loaded_netrw             = 1
    let g:loaded_netrwPlugin       = 1
    let g:loaded_netrwSettings     = 1
    let g:loaded_netrwFileHandlers = 1
    augroup my-fern-hijack
      autocmd!
      autocmd BufEnter * ++nested call s:hijack_directory()
    augroup END
  endfunction

Hi. Thanks for the plugin.

When I open fern with the command :Fern . no files show up. It's not happening with the last tag release or with the :Fern . -drawer command. I've already removed the plugin and installed it again to keep the cache problem away.

Currently fern.vim does not support Windows. I'm working on it.

Add complete functions for

:Fern {expr} [-drawer][-keep][-toggle][-width={width}][-reveal={reveal}]

where {expr} is % with/without modifiers, {bufname}, {dir} or {scheme}:///{path}

• Optional arguments
• {bufname}
• {dir}
• {scheme} in fern#scheme#...
• {path} completed by {scheme} specific function
• {reveal} completed by {scheme} specific function

I LOVE NERDTREE keymap to file manipulation menu, but how it work in this plugin?

Hi, I have another suggestion to do. Sorry about that, but I'm very eager about this plugin.

In coc.nvim, when I can perform actions under some item, I can press the tab on it and a list of actions is showing in the buffer.

What do you think about that? This prevents the user to keep track of all the shortcuts the plugin has, besides to show him new options easily without the need to check the help or the readme.

mkdir a
touch a/a
touch a/b
touch a/c
ln a b

"ls" vs "find" impl.

Now hidden, include, exclude status are not kept. It would be better to keep those status in a buffer name like

fern://{hash}/{path};hidden&include={patter]}&exclude={pattern}

When cursor on the fern buffer, can't open new tab with tabedit command.

Reproduce steps

1. Open fern drawer by :Fern -drawer
2. Execute command :tabedit

Expected

Open new tab

Actual

Open a new buffer in the window containing the fern buffer

I stumbled on this repo and seems like a really good idea. It is something I was planing to do in the future. I had even suggested something similar for vim to have vim/vim#3573 (comment)

It would be great if we have a generic plugin something like tree.vim which only cares about enabling other plugins to use the treeview. Similar to vs-code TreeDataProvider api - https://code.visualstudio.com/api/references/vscode-api#TreeDataProvider. Then can there be a plugin called tree-file.vim which only cares about file treeview. And it can be optimized for example starting a file watcher to make it more efficient. I would love to use it from vim-lsp so that we can have code tree view navigation.

I have started something very similar for a ctrlp.vim alternative - https://github.com/prabirshrestha/quickpick.vim It is at a very early stage.

While netrw is a default file browser, fila should follow that manner.

It would be nice if there is a way to use a custom locator when power users want to change the behavior of open related behaviors. For example, some people want to avoid opening a buffer on quickfix window but location-list window (a default locator avoid both.)

So that the cursor stays on a node which was a root node of the previous tree.

1. User execute open:vsplit action on A
2. Fern ask WindowLocator to focus suitable window
3. WindowLocator move foucs from A to B
4. Fern execute vsplit {bufname} on B
5. C is opened at left side of B
6. <C-w><C-p> move focus to B because it's previous

Above behavior is perfect but User feel it's unexpected because User thought the focus has moved from A to C directly (A -> B has programatically performed.)

Sometimes user want to see all childrens in one action.

Not sure if it's because of a virtual machine but it seems fern.vim works extremely slow in Windows. Try execute :Fern . with g:fern_profile = 1

note: Use https://github.com/tyru/capture.vim to capture the profile by :Capture mes after :Fern .

rename action cannot be applied to a directory

There is nothing in the docs about that. Is there some way to configure fern to show the hidden files?

Thanks.

fern.vim is not opening a file relative to the pwd dir.

A file opened with fern:

A file opened with fzf:

Both were opened in the same vim session.

Changed action name
/<Plug>(fila-action-open-select)/<Plug>(fila-action-edit-select)/

Somehow, when C:\ has specified fern, a current directory is used instead in Windows.

Please consider the following scenario:

:e a.file
:e b.file
:bd

The result would be a.file open.

Doing the same with :Fern -drawer:

open:edit a.file
open:edit b.file
:bd

The result: vim quits (unless any changes were done to the files).

Would be nice to have opened buffers to act like regular ones (I don't really understand how this is possible to have another type of buffer, but maybe I'm missing something here... Didn't look at the source of fern)

Edit: Apparently it only happens with -drawer. Still investigating...
