Description

I'm using https://github.com/hrsh7th/nvim-cmp and I want to complete paths in input window when add/rename/move/copy the files and directories.

I read the code and find it is not work.

  1. The callers of inputs.input not pass the parameter completion.

https://github.com/nvim-neo-tree/neo-tree.nvim/blob/20c2f2f5ba083bbb1e37b8bc3d590621434f31e9/lua/neo-tree/sources/filesystem/lib/fs_actions.lua#L334-L383

  1. When use_popups_for_input = true, should_use_popup_input() is true. But there is no handle for completion, and the nui.input has no completion option.

Do you have any plan to implement the completion? I could help to implement it. I just want to use nvim-cmp to complete paths and use the keymaps of nvim-cmp to trigger completion.

Research direction
The issue points to specific files: fs actions.lua (lines 334-383) which calls inputs.input without a completion parameter, and inputs.lua (lines 32-53) which defines the input function. The user also notes that when use popups for input is true, nui.input is used and it lacks a completion option. Research should investigate how to modify the input function to accept a completion argument and integrate with nvim cmp's completion engine. Consider implementing a custom completion source or mapping to trigger nvim cmp for path completions. Review nvim cmp's documentation for custom sources and mappings.
