inquire is a library for building interactive prompts on terminals.

It provides several different prompts in order to interactively ask the user for information via the CLI. With inquire, you can use:

• Text to get text input from the user, with built-in auto-completion support;
• Editor* to get longer text inputs by opening a text editor for the user;
• DateSelect* to get a date input from the user, selected via an interactive calendar;
• Select to ask the user to select one option from a given list;
• MultiSelect to ask the user to select an arbitrary number of options from a given list;
• Confirm for simple yes/no confirmation prompts;
• CustomType for text prompts that you would like to parse to a custom type, such as numbers or UUIDs;
• Password for secretive text prompts.

Check out the GitHub repository to see demos of what you can do with inquire.

Simple Example

use inquire::{Text, validator::{StringValidator, Validation}};

fn main() {
let validator: StringValidator = &|input| if input.chars().count() > 140 {
Ok(Validation::Invalid("You're only allowed 140 characters.".into()))
} else {
Ok(Validation::Valid)
};

let status = Text::new("What are you thinking about?")
.with_validator(validator)
.prompt();

match status {
Ok(status) => println!("Your status is being published..."),
Err(err) => println!("Error while publishing your status: {}", err),
}
}
