[Windows Cygwin] Filepaths do not display correctly & files do not open reliably

[gbroques]

Filepaths are not displayed correcty in the picker (see below :Telescope frecency screenshot ), and sometimes when I select a file an empty buffer opens instead.

I haven't been able to reproduce the latter behavior consistently though, but I suspect it's related.

I expect to see filepaths displayed as :Telescope find_files displays them (see below screenshot).

Steps to Reproduce

1. Use Windows & Cygwin.
2. Clone telescope-frecency.nvim in /cygdrive/c/Users/Public/Projects.
3. Open Neovim in root of telescope-frecency.nvim directory.
4. Run :Telescope frecency.

:Telescope frecency	:Telescope find_files

The following is a link to my Telescope configuration: https://github.com/gbroques/neovim-configuration/blob/919ffbd07538ab432c6eba088c3330793e10b6ad/lua/plugins/fuzzy-finder.lua#L62-L113

telescope.setup({
  defaults = {
    wrap_results = true,
    results_title = false,
    file_ignore_patterns = {
      "^.git/"
    },
    layout_config = {
      -- Fullscreen
      width = { padding = 0 },
      height = { padding = 0 },
    },
  },
  -- omitted ...
  extensions = {
    frecency = {
      default_workspace = 'CWD',
      prompt_title = 'Find Files',
      sorter = require('telescope.config').values.file_sorter()
    }
  }
})

I'm currently pinned to commit de410701811f4142315ce89183256a969a08ff9d which is from early December.

Probably this is because of vim.fs module's implementation. It cannot detect Windows file paths (including \) validly.

After #156, this plugin takes more priority to use rg / fd executable than vim.fs module to show entries. Can you test the latest master after installing rg / fd?

Thank you for the reply @delphinus! :)

I updated to the latest commit 9c18474d0a4b82435ce141c2a21d9bd7b9189272, and I do have rg and fd installed.

Unfortunately it still doesn't work.

The behavior is slightly different now:

1. I open nvim in a project directory.
2. Execute :Telescope frecency
3. Then the picker list is empty until I type a character.
4. Also, I see the below warning upon executing :Telescope frecency.

[telescope] [WARN 21:23:10] C:/Users/{Username}/AppData/Local/nvim-data/lazy/telescope.nvim/lua/telescope/pickers.lua:493: Finder failed with msg: .../nvim-data/lazy/telescope.nvim/lua/telescope/pickers.lua:1149: E5560: nvim_buf_is_valid must not be called in a lua loop callback

If you need me to add some print debug statements somewhere in the code to help troubleshoot this, then let me know!

I can report the output I see in this thread.

[delphinus]

@gbroques Thank you for further info!

It seems that rg cannot return any entry and telescope looks stuck. Please run Neovim with env variable: DEBUG_PLENARY=1. Such as,

$ export DEBUG_PLENARY=1
$ nvim
# and run :Telescope frecency

Then :mes shows debugging logs by frecency. Paste them here like below.

(I have cut some long paths in logs)

[gbroques]

Please run Neovim with env variable: DEBUG_PLENARY=1.

Thanks for posting these instructions @delphinus! That's a really good debugging tip.

Also, I realized the behavior is inconsistent and I see the following two scenarios:

1. sometimes the picker list is empty until I type a character and I see the "nvim_buf_is_valid must not be called in a lua loop callback" warning.
2. other times the picker list populates immediately upon running :Telescope frecency.

Additionally, I ran :lua print(vim.o.shell) and it's cmd.exe.

I set the DEBUG_PLENARY environment variable to 1, ran nvim, and then :Telescope frecency.

The following is the output for :Telescope frecency during scenario 1.:

I found problems in vim.fs.joinpath & vim.fs.dir that they does not think Windows over. Maybe #168 fix this issue. Still testing……

I found problems in vim.fs.joinpath & vim.fs.dir that they does not think Windows over. Maybe #168 fix this issue. Still testing……

Thank you @delphinus!

I checked out that branch, and tested it.

Some of the paths are fixed, but I see duplicates of some paths which still display incorrectly with the "C:\Users.." in the front (see below screenshots).

Also, I deleted the file_frecency.bin file to try and remove any old paths.

Lastly, I'm still seeing the behavior where the picker occassionaly fails to populate until I type a character, and I see a " E5560: nvim_buf_is_valid must not be called in a lua loop callback" warning.

[delphinus]

I found a problem for logic for importing entries at the first launch.

If file_frecency.bin does not exist, this plugin imports entries from v:oldfiles. If v:oldfiles contains duplicated entries such as both c:\foo\bar.txt and c:/foo/bar.txt, it also imports them and you will see matched both entries in query.

We should improve this by detecting duplication of paths. I will try it.

---

But another problem. E5560: nvim_buf_is_valid must not be called in a lua loop callback cannot be seen in my env. I've prepared env on Windows with this minimal init.lua.

Ah, you're using Cygwin! I did this in plain Windows. I will also setup Cygwin and try the same one.

Ok, that makes sense.

I'll clear my v:oldfiles by editing $XDG_DATA_HOME/nvim/shada/main.shada as instructed in this thread, and see if I can remove the duplicate bad paths manually.

Can you show your settings for telescope?

Sure thing!

The following should be my complete telescope configuration: https://github.com/gbroques/neovim-configuration/blob/53272b8a09c2c905cdb2f3802d9ffd1aff6827ef/lua/plugins/fuzzy-finder.lua#L2-L115

Currently, I'm pinned to a telescope commit, 2ea8dc, from 6 months ago. I can try updating to the latest commit on master.

Let me know if you need any other help to reproduce this, or have questions.

Thanks again for all your support in solving these issues!

[delphinus]

I see. Your setup seems to have no mistake.

I can try updating to the latest commit on master.

Yes. This can help you, maybe.

[gbroques]

I can try updating to the latest commit on master.

Yes. This can help you, maybe.

I updated my telescope plugin to the latest commit on master, 36dce626, and see the same behavior.

@gbroques I did changes in #168 and fixed almost all of bugs in using Windows.

But I found one problem: #170. This is due to the logic of plenary.nvim, that is needed by telescope.nvim itself. I think this cannot be solved with simple way...

---

And I also tried v0.9.0. But again I could not see E5560: nvim_buf_is_valid must not be called in a lua loop callback. Can you try with minimal init.lua such as I described in this comment?

[delphinus]

I merged #168. From now, please check behavior in the latest master.

170 still remains because it cannot be fixed. You can see the problem only in Cygwin, not in Windows.
