Telescope cannot create the history file

[xarthurx]

Description

Also reported here: https://www.reddit.com/r/neovim/comments/v6towp/telescope_tries_to_create_cc_folder/

When doing a clean install, and enable the history functionality, telescope is unable to create the new folder/file.

The direct behavior is after entering the TS UI, I cannot get out. (by either pressing or to select some files).

Neovim version

NVIM v0.9.1
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

Operating system and version

Windows

Telescope version / branch / rev

2d92125

checkhealth telescope

==============================================================================
telescope: 

- ERROR No healthcheck found for "telescope" plugin.

Steps to reproduce

1. clean install nvim
2. install telescope
3. run telescope find-file, find-history, etc.

Expected behavior

No response

Actual behavior

no errors, the history file/folder should be created correctly.

Minimal config

vim.cmd [[set runtimepath=$VIMRUNTIME]]
vim.cmd [[set packpath=/tmp/nvim/site]]
local package_root = '/tmp/nvim/site/pack'
local install_path = package_root .. '/packer/start/packer.nvim'
local function load_plugins()
  require('packer').startup {
    {
      'wbthomason/packer.nvim',
      {
        'nvim-telescope/telescope.nvim',
        requires = {
          'nvim-lua/plenary.nvim',
          { 'nvim-telescope/telescope-fzf-native.nvim', run = 'make' },
        },
      },
      -- ADD PLUGINS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
    },
    config = {
      package_root = package_root,
      compile_path = install_path .. '/plugin/packer_compiled.lua',
      display = { non_interactive = true },
    },
  }
end
_G.load_config = function()
  require('telescope').setup()
  require('telescope').load_extension('fzf')
  -- ADD INIT.LUA SETTINGS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
end
if vim.fn.isdirectory(install_path) == 0 then
  print("Installing Telescope and dependencies.")
  vim.fn.system { 'git', 'clone', '--depth=1', 'https://github.com/wbthomason/packer.nvim', install_path }
end
load_plugins()
require('packer').sync()
vim.cmd [[autocmd User PackerComplete ++once echo "Ready!" | lua load_config()]]

manually creating telescope-history will also not work.
As somehow telescope tries to concatenate the current dir with the telescope-history dir.
Is this a plenary problem?

[xarthurx]

OK, I found the problem:

I use set shellslash on Windows, to avoid the issue that I cannot open file paths with ().
This has no problem if TS has been run, but will create the above PATH issue for clean system.

What I did finally is:

1. unset shellslash
2. run TS once
3. set shellslash back.

Now everything works.

In a config file? Or every time you open Nvim? Could you give an example? I'm trying to do the same but It doesn't result for me.

[xarthurx]

You can set it in your config file, or :set shellslash.
You need to delete the whole nvim-data folder if you're on WIndows.

yeah this is a plenary.path problem: nvim-lua/plenary.nvim#254

it was built without shellslash in mind. You can maybe try nvim-lua/plenary.nvim#371 (note you probably want to rebase the PR its kinda old), so we can maybe find a working solution for this problem.

I just dont have a windows machine at hand to do the required testing

I wrote on that PR to get some attentions.

For Windows machine, perhaps a Virtual Machine?
