CLInput

Command Line Input

How to use

Basic method

```rust // 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 yesorno = 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

```rust let promptlist = 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" ].tovec()) )

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