Snacks.explorer: custom yank operation?

[markhagemann]

In neo-tree there was a solution given for a prompt to ask what type of yank on the filepath to do. I am just wondering if anyone has already done similar? I think the main thing I need to do is figure out what to call to get the nodes. Admittedly I haven't done a deep dive here other than checking for relative in the explorer code.

Alternatively it'd be good to separate out y for relative to CWD and Y for relative to HOME.

The custom function from the neo-tree discussion below:

local function copy_path(state)
  -- NeoTree is based on [NuiTree](https://github.com/MunifTanjim/nui.nvim/tree/main/lua/nui/tree)
  -- The node is based on [NuiNode](https://github.com/MunifTanjim/nui.nvim/tree/main/lua/nui/tree#nuitreenode)
  local node = state.tree:get_node()
  local filepath = node:get_id()
  local filename = node.name
  local modify = vim.fn.fnamemodify

  local results = {
    filepath,
    modify(filepath, ":."),
    modify(filepath, ":~"),
    filename,
    modify(filename, ":r"),
    modify(filename, ":e"),
  }

  vim.ui.select({
    "1. Absolute path: " .. results[1],
    "2. Path relative to CWD: " .. results[2],
    "3. Path relative to HOME: " .. results[3],
    "4. Filename: " .. results[4],
    "5. Filename without extension: " .. results[5],
    "6. Extension of the filename: " .. results[6],
  }, { prompt = "Choose to copy to clipboard:" }, function(choice)
    if choice then
      local i = tonumber(choice:sub(1, 1))
      if i then
        local result = results[i]
        vim.fn.setreg("*", result)
        vim.notify("Copied: " .. result)
      else
        vim.notify("Invalid selection")
      end
    else
      vim.notify("Selection cancelled")
    end
  end)
end

window = {
	mappings = {
		["Y"] = copy_path,
		-- Additional mappings
	},
}

There is still room for improvement. This code is just a mapping of the code you provided on snacks.nvim.

[markhagemann]

Much appreciated! That works great.

For a y vs Y key bind solution, here's what works for me.

    "snacks.nvim",
    keys = {
      picker = {
        sources = {
          explorer = {
            win = {
              list = {
                keys = {
                  ["y"] = "yank_relative_cwd",
                  ["Y"] = "yank_relative_home",
                },
              },
            },
            actions = {
              yank_relative_cwd = function(_, item)
                local path = vim.fn.fnamemodify(item.file, ":.")
                vim.fn.setreg("+", path)
                vim.fn.setreg('"', path)
                vim.notify("Yanked: " .. path)
              end,
              yank_relative_home = function(_, item)
                local path = vim.fn.fnamemodify(item.file, ":~")
                vim.fn.setreg("+", path)
                vim.fn.setreg('"', path)
                vim.notify("Yanked: " .. path)
              end,
            },
          },
        },
      },
    },

Exactly what I was looking for! Thank you!
