Effortlessly build beautiful command-line apps with Rust 🦀✨

Beautiful, minimal, opinionated CLI prompts inspired by the @clack/prompts npm package.

cargo add cliclack

cliclack in action

cargo run --example basic
cargo run --example log

💎 Fancy minimal UI
✅ Simple API
🎨 Theme support

Setup

The intro and outro/outro_cancel functions will print a message to begin and end a prompt session respectively.

use cliclack::{intro, outro};

intro("create-my-app")?;
// Do stuff
outro("You're all set!")?;

Input

The input prompt accepts a single line of text trying to parse it into a target type. Multiline input can be enabled using the multiline() switch, and autocomplete using autocomplete().

use cliclack::input;

let path: String = input("Where should we create your project?")
    .placeholder("./sparkling-solid")
    .validate(|input: &String| {
        if input.is_empty() {
            Err("Please enter a path.")
        } else if !input.starts_with("./") {
            Err("Please enter a relative path")
        } else {
            Ok(())
        }
    })
    .interact()?;

🎨 Theme

A custom theme can be applied for UI rendering. An example of theme customization:

cargo run --example theme

🚥 Progress Bar

Starting from cliclack = "0.2.3", progress bars and multi-progress bars are supported.

🔍 Autocomplete

Starting from cliclack = "0.5.0", the input prompt supports autocompletion.
