Action to copy path and filename of result?

[benfrain]

Is there an existing Action to copy the filename and path of a result to the clipboard, rather than opening it?

[gennaro-tedesco]

You could define the action yourself as

...
actions = {
  ["ctrl-y"] = {
    fn = function(selected)
      vim.fn.setreg("*", selected[1])
    end,
    desc = ...,
},

where selected[1] is the entire displayed selected string, you might need to vim.fs.normalize if you want the full path.

Also take a look at how git commits does it, for files use path.entry_to_file to remove the icons / restore formatting.

fzf-lua/lua/fzf-lua/actions.lua

Lines 686 to 697 in 8efb28f

	M.git_yank_commit = function(selected, opts)
	local commit_hash = match_commit_hash(selected[1], opts)
	if vim.o.clipboard == "unnamed" then
	vim.fn.setreg([[*]], commit_hash)
	elseif vim.o.clipboard == "unnamedplus" then
	vim.fn.setreg([[+]], commit_hash)
	else
	vim.fn.setreg([["]], commit_hash)
	end
	-- copy to the yank register regardless
	vim.fn.setreg([[0]], commit_hash)
	end

Does this support multiple selections?

Craft your own action and you can do wherever you want with the other entires.

My setup for fzf-lua now contains this but the key combo does nothing. Could anyone point out how to correct?

local path = require("fzf-lua.path")
get_line_and_path = function(selected, opts)
  local file_and_path = path.entry_to_file(selected[1], opts)
  if vim.o.clipboard == "unnamed" then
    vim.fn.setreg([[*]], file_and_path)
  elseif vim.o.clipboard == "unnamedplus" then
    vim.fn.setreg([[+]], file_and_path)
  else
    vim.fn.setreg([["]], file_and_path)
  end
  -- copy to the yank register regardless
  vim.fn.setreg([[0]], file_and_path)
end

require("fzf-lua").setup({
  "border-fused",
  fzf_opts = { ["--wrap"] = true },
  previewers = {
    builtin = {
      syntax_limit_b = -102400, -- 100KB limit on highlighting files
    },
  },
  winopts = {
    preview = {
      wrap = true,
    },
  },
  grep = {
    rg_glob = true,
    -- first returned string is the new search query
    -- second returned string are (optional) additional rg flags
    -- @return string, string?
    rg_glob_fn = function(query, opts)
      local regex, flags = query:match("^(.-)%s%-%-(.*)$")
      -- If no separator is detected will return the original query
      return (regex or query), flags
    end,
  },
  defaults = {
    git_icons = false,
    file_icons = false,
    color_icons = false,
    formatter = "path.filename_first",
  },
  actions = {
    files = {
      ["ctrl-y"] = get_line_and_path,
    },
  },
})

I didn’t test but it seems accurate, when you say does nothing what do you mean? This copies it to a different register based on the clipboard setting, if you’re trying to ctrl-v outside of neovim it won’t work unless you’re using unnamedplus.

Use random print statements to see if your function gets called and the values of your vars to debug.

Also note you can copy the entry without exiting fzf with:

actions = {
    files = {
      ["ctrl-y"] = { fn = get_line_and_path, exec_silent = true }
    },
  },

Hmm, when I run it, there is nothing on screen, and nothing is saved to any register. When I use your action, it prints table:0x1102ef8248 but again, I see nothing in any register 🤷‍♂️

I have tried adding print("hello") into the get_line_and_path function but nothing is displayed in the command line area too. Sorry, I'm very inexperienced with Lua as you may have guessed!

Now is the time to get your hands dirty troubleshooting :)

If it prints “function 0x” you gave it a function object to print, try print(1, object) so you can track the code route and you’ll figure it out, see which route is taken and which register is saved, if you want only the clipboard you only need this line vim.fn.setreg([[+]], file_and_path) but it needs to be changed to vim.fn.setreg([[+]], file_and_path.path) (as entry is a table).

To dump table objects use vim.print(file_and_path).

Thanks for 'teaching me to fish' a little there! I was able to print the table with vim.print(file_and_path) and then view the output with :messages and it turns out I need the .stripped key of the table so a simple amendment to local file_and_path = path.entry_to_file(selected[1], opts).stripped gets me what I need. Thanks for the help!!

Thanks for the update @benfrain!

seems I spoke too soon, with the mapping active, none of the normal 'enter to open file' mappings work. As soon as I comment out

  actions = {
    files = {
      ["ctrl-y"] = { fn = get_line_and_path, exec_silent = true },
    },
  },

it behaves itself. Any idea why that might be?

You need to inherit the default actions, add true at first index:

  actions = {
    files = {
      true,
      ["ctrl-y"] = { fn = get_line_and_path, exec_silent = true },
    },
  },

Perfect thanks
