@Conni2461 I'm thinking some of this probably belongs in plenary.path.

@davisthedev I'm also curious if using :set shellslash helps in any way in telescope.

[davisthedev]

@jamestrew I did try :set shellslash before I started any dev work. It did not make a difference for telescope.

I would be happy to add this to plenary if that would help?
I am super new to lua and the neovim ecosystem so I may have some questions.

Semi-related issue with plenary not gracefully handling windows paths set shellslash #2651

[Conni2461]

i think we should do that in plenary. And we already had a discussion about this in plenary

nvim-lua/plenary.nvim#254
nvim-lua/plenary.nvim#371

[jamestrew]

The shellslash stuff looks very hairy to fix. I don't think I have the capacity/patience to fix it especially with this being a cross-platform/windows issue and I don't easily have a windows environment to test this kind of stuff.

And I believer when we're looking to eventually deprecate plenary and possibly rely more on neovim core of path stuff.
