	Prompts for user input using the wanted kind of prompt:

	* `"text"` - Prompts for a plain text string from the user
	* `"confirm"` - Prompts the user to confirm with y / n (yes / no)
	* `"select"` - Prompts the user to select *one* value from a list
	* `"multiselect"` - Prompts the user to select *one or more* values from a list
	* `nil` - Equivalent to `"text"` with no extra arguments

	@param kind The kind of prompt to use
	@param message The message to show the user
	@param defaultOrOptions The default value for the prompt, or options to choose from for selection prompts

	Built-in standard input / output & utility functions

	### Example usage

	```lua
	local stdio = require("@lune/stdio")

	-- Prompting the user for basic input
	local text: string = stdio.prompt("text", "Please write some text")
	local confirmed: boolean = stdio.prompt("confirm", "Please confirm this action")

	-- Writing directly to stdout or stderr, without the auto-formatting of print/warn/error
	stdio.write("Hello, ")
	stdio.write("World! ")
	stdio.write("All on the same line")
	stdio.ewrite("\nAnd some error text, too")

	-- Reading the entire input from stdin
	local input = stdio.readToEnd()
	```

--[=[
	@within Stdio
	@tag must_use

	Return an ANSI string that can be used to modify the persistent output color.

	Pass `"reset"` to get a string that can reset the persistent output color.

	### Example usage

	```lua
	stdio.write(stdio.color("red"))
	print("This text will be red")
	stdio.write(stdio.color("reset"))
	print("This text will be normal")
	```

	return nil :: any
end

--[=[
	@within Stdio
	@tag must_use

	Return an ANSI string that can be used to modify the persistent output style.

	Pass `"reset"` to get a string that can reset the persistent output style.

	### Example usage

	```lua
	stdio.write(stdio.style("bold"))
	print("This text will be bold")
	stdio.write(stdio.style("reset"))
	print("This text will be normal")

	Formats arguments into a human-readable string with syntax highlighting for tables.

	@param ... The values to format
	@return The formatted string
]=]

--[=[

	Writes a string directly to stdout, without any newline.

	@param s The string to write to stdout
]=]
function stdio.write(s: string) end

--[=[
