File operation between neovim instances

[tienlonghungson]

Neo-tree can sync its clipboard across multiple trees, either globally (within the same Neovim instance) or universally (across all Neovim instances). Try clipboard.sync = "global" | "universal". This enables copy/cut/paste files/dir between neovim instances.

Do we have the same for Snacks.explorer?

Doesn't the explorer use the system clipboard out of the box? You can also use "<reg>y if needed.

	#### Copy/Paste with Registers
	Alternative workflow using yank and paste:
	1. **Select files** with `<Tab>` or visual mode
	2. Press `y` to **yank** file paths to register
	3. Navigate to target directory
	4. Press `p` to **paste** (copies files from register)
	This works across different explorer instances and even after closing/reopening!

vim.fn.setreg(vim.v.register or "+", value, "l")

local files = vim.split(vim.fn.getreg(vim.v.register or "+") or "", "\n", { plain = true })

That works. Tks

Hi @drowning-cat , sorry for asking you again. I tested this feature on different tmux's windows, panes, and it did not work. It just works on the same tmux's pane. For more information, I am using tmux on a remote machine via ssh

My bad. By default, vim.v.register returns ".

From :help v:register:

					*v:register* *register-variable*
v:register
		The name of the register in effect for the current normal mode
		command (regardless of whether that command actually used a
		register).  Or for the currently executing normal mode mapping
		(use this in custom commands that take a register).
		If none is supplied it is the default register '"', unless
		'clipboard' contains "unnamed" or "unnamedplus", then it is
		"*" or '+'.
		Also see |getreg()| and |setreg()|

I didn't test with SSH, but there are a few ways to solve the problem:

1. Use "+y when needed.

2. Always use system clipboard:

   From LazyVim/blob/.../lua/lazyvim/config/options.lua#L55-L57:

   -- only set clipboard if not in ssh, to make sure the OSC 52
   -- integration works automatically.
   vim.o.clipboard = vim.env.SSH_CONNECTION and "" or "unnamedplus" -- Sync with system clipboard

3. Override explorer_yank/explorer_paste:

   vim.pack.add({
     { src = "https://github.com/folke/snacks.nvim" },
   })
   
   local Actions = require("snacks.explorer.actions").actions
   
   local with_sysclip = function(fn)
     local clipboard = vim.o.clipboard
     vim.o.clipboard = vim.env.SSH_CONNECTION and "" or "unnamedplus"
     vim.schedule(function()
       fn()
       vim.o.clipboard = clipboard
     end)
   end
   
   require("snacks").setup({
     picker = {
       sources = {
         explorer = {
           actions = {
             explorer_yank = function(picker) --[[Override]]
               with_sysclip(function()
                 Actions.explorer_yank(picker)
               end)
             end,
             explorer_paste = function(picker) --[[Override]]
               with_sysclip(function()
                 Actions.explorer_paste(picker)
               end)
             end,
           },
         },
       },
     },
   })
   
   vim.keymap.set("n", "<Space>e", function()
     Snacks.explorer()
   end)

     },
   })
   
   vim.keymap.set("n", "<Space>e", function()
     Snacks.explorer()
   end)

Tks, using "+y and "*y works.
