CLInput

Command Line Input

How to use

Basic method

// Basic question with no validation
let res = Prompt::new("How is it going?").ask();

// Asks a question to stdout and loops until a valid choice is made
let yes_or_no = Prompt::new("Continue?")
	.choices([ "y", "Y", "n", "N" ].to_vec())
	.ask();

// Custom validation
let non_blank = Prompt::new("Enter something...")
	.validate(|input: String| {
		if input.len() > 0 {
			return Ok(input);
		}
		return Err(PromptError::ValidateError(
			String::from("Cannot be blank")
		))
	})
	.ask();

Builder pattern

let prompt_list = PromptList::new()
	.add(
		Prompt::new("What is your name?")
			.validate(|input: String| {
				if input.len() > 0 {
					return Ok(input);
				}
				return Err(PromptError::ValidateError(
					String::from("Cannot be blank")
				))
			})
	)
	.add(
		Prompt::new("Yes or no?")
			.choices([ "y", "Y", "n", "N" ].to_vec())
	)

let res = prompt_list.next().ask();
