--- Prompts the user to pick a single item from a collection of entries
---
---@param items table Arbitrary items
---@param opts table Additional options
--- - prompt (string|nil)
--- Text of the prompt. Defaults to `Select one of:`
--- - format_item (function item -> text)
--- Function to format an
--- individual item from `items`. Defaults to `tostring`.
--- - kind (string|nil)
--- Arbitrary hint string indicating the item shape.
--- Plugins reimplementing `vim.ui.select` may wish to
--- use this to infer the structure or semantics of
--- `items`, or the context in which select() was called.
---@param on_choice function ((item|nil, idx|nil) -> ())
--- Called once the user made a choice.
--- `idx` is the 1-based index of `item` within `item`.
--- `nil` if the user aborted the dialog.
---
---
--- Example:
--- <pre>
--- vim.ui.select({ 'tabs', 'spaces' }, {
--- prompt = 'Select tabs or spaces:',
--- format_item = function(item)
--- return "I'd like to choose " .. item
--- end,
--- }, function(choice)
--- if choice == 'spaces' then
--- vim.o.expandtab = true
--- else
--- vim.o.expandtab = false
--- end
--- end)
--- </pre>

--- Prompts the user for input
---
---@param opts table Additional options. See |input()|
--- - prompt (string|nil)
--- Text of the prompt. Defaults to `Input: `.
--- - default (string|nil)
--- Default reply to the input
--- - completion (string|nil)
--- Specifies type of completion supported
--- for input. Supported types are the same
--- that can be supplied to a user-defined
--- command using the "-complete=" argument.
--- See |:command-completion|
--- - highlight (function)
--- Function that will be used for highlighting
--- user inputs.
---@param on_confirm function ((input|nil) -> ())
--- Called once the user confirms or abort the input.
--- `input` is what the user typed.
--- `nil` if the user aborted the dialog.
---
--- Example:
--- <pre>
--- vim.ui.input({ prompt = 'Enter value for shiftwidth: ' }, function(input)
--- vim.o.shiftwidth = tonumber(input)
--- end)
--- </pre>
