Is there a way to retrieve the user input from the fzf_exec picker?

[wisonye]

I'm migrating my Project Commands plugin from Telescope to Fzf-lua, it works like this:

Run the plugin to show a picker with the pre-filled command (search from the current folder e.g. *.sh) and fill into the picker, user can pick the command to run. Also, user is able to type the new command to run and add it the command list as well.

But I can't find a way to get back the user input... any idea?:)

Here is how I call fzf_exec:

-- `CMD_LIST` is a string array

require('fzf-lua').fzf_exec(CMD_LIST, {
    prompt = " Project commands ('ctrl+d' to delete item) ",
    winopts = {
        width = 0.50,
        height = 0.40,
    },
    actions = {
        ["default"] = function(selected)
            if (enable_debug_print) then
                print(string.format(
                    ">>> selected: %s, type: %s",
                    vim.inspect(selected),
                    type(selected)
                ))
            end

            --
            -- >>>> Question: How to do I get back the user command from the picker's input???
            -- >>>> Question: How to do I get back the user command from the picker's input???
            -- >>>> Question: How to do I get back the user command from the picker's input???
            --

            -- execute_command_v2(user_input_command)

        end,

        --
        -- `ctrl+d` to delete selected item
        --
        ["ctrl-d"] = function(selected)
            if (enable_debug_print) then
                print(string.format(
                    ">>> selected to be deleted: %s, type: %s",
                    vim.inspect(selected),
                    type(selected)
                ))
            end

            if #selected <= 0 then return end

            local index_to_delete = -1
            for index, value in ipairs(CMD_LIST) do
                if value == vim.trim(selected[1]) then
                    index_to_delete = index
                    break
                end
            end

            if index_to_delete ~= -1 then
                table.remove(CMD_LIST, index_to_delete)
            end

            --- Resume (also refresh the UI)
            require('fzf-lua').actions.resume()
        end,
    },
})

Use opts.last_query from the second arg of the function callback:

actions = {
        ["enter"] = function(selected, opts)
          -- user input is in opts.last_query

For more info see how fzf-lua git branch add bind works:

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

Lines 799 to 817 in 3e644b8

	M.git_branch_add = function(selected, opts)
	-- "reload" actions (fzf version >= 0.36) use field_index = "{q}"
	-- so the prompt input will be found in `selected[1]`
	-- previous fzf versions (or skim) restart the process instead
	-- so the prompt input will be found in `opts.last_query`
	local branch = opts.last_query or selected[1]
	if type(branch) ~= "string" or #branch == 0 then
	utils.warn("Branch name cannot be empty, use prompt for input.")
	else
	local cmd_add_branch = path.git_cwd(opts.cmd_add, opts)
	table.insert(cmd_add_branch, branch)
	local output, rc = utils.io_systemlist(cmd_add_branch)
	if rc ~= 0 then
	utils.error(unpack(output))
	else
	utils.info("Created branch '%s'.", branch)
	end
	end
	end

Many thanks, it works as expected!:)

hello @ibhagwan, it works correctly when we use an action. however, is it possible to retrieve user input from the keymap?

keymap = {
  fzf = {
    ["a"] = function(opts)
      require('utils.func').debug(opts)
    end,
  },
}

[ibhagwan]

Use FzfLua.get_info().last_query

i'm getting this when i print the get_info()

{
  cmd = "buffers",
  fnc = "buffers",
  mod = "fzf-lua.providers.buffers"
}
