claui

Command Line Arguments (to graphical) User Interface

A GUI generator for clap that uses egui.

Builder Example

```rust use clap::{arg, Command};

fn main() { let app = Command::new("Builder Greeter") .author("Grant Handy grantshandy@gmail.com") .version("1.2.3") .about("A builder example for claui") .arg(arg!(--name "Your name").default_value("Joe")) .arg(arg!(--goodbye "Say goodbye"));

claui::run(app, |matches| {
    println!("Hello, {}!", matches.value_of("name").unwrap());

    if matches.is_present("goodbye") {
        println!("Goodbye!");
    }
});

} ```

Derive Example

```rust use clap::{CommandFactory, Parser};

[derive(Parser, Debug)]

[clap(

name = "Derive Greeter",
author = "Grant Handy <grantshandy@gmail.com>",
version = "1.2.3",
about = "A derive example for claui"

)] struct Args { #[clap(long, default_value = "Joe", help = "Your name")] name: String, #[clap(long, help = "Say goodbye")] goodbye: bool, }

fn main() { let app = Args::command();

claui::run(app, |matches| {
    println!("Hello, {}!", matches.value_of("name").unwrap());

    if matches.is_present("goodbye") {
        println!("Goodbye!");
    }
});

} ```

Comparison with klask

Klask is another GUI generator for clap that uses egui, but claui and klask work in different ways. Klask runs your code by running itself as a child with an environment variable to ignore its GUI, then capturing the child's stdout. Claui only runs one process; it spawns your code in another thread and then reroutes all of your stdout into a buffer on each frame through shh.
