--- Example demonstrating the cli.Confirm widget.

-- Step 1: pick a pre-defined response set using a custom Confirm widget.
-- Step 2: run a confirmation widget using that set, then show the result.

local t = require("terminal")
local Confirm = require("terminal.cli.confirm")



local function main()
  t.text.push { fg = "cyan", brightness = "high" }
  t.output.print("cli.Confirm demo")
  t.text.pop()



  -- step 1: pick a response set via a custom Confirm widget
  local set_names = {}

  end
  table.sort(set_names)

  local responses = {}

  local chosen_name, err = choice()
