//! `Mingling` Example - Basic
//!
//! # How to Run
//! ```bash
//! cargo run --manifest-path ./examples/example-basic/Cargo.toml -- hello World
//! ```
use mingling::prelude::*;
// Define dispatcher `HelloCommand`, directing subcommand "hello" to `HelloEntry`
dispatcher!("hello", HelloCommand => HelloEntry);
fn main() {
// Create program
let mut program = ThisProgram::new();
// Add dispatcher `HelloCommand`
program.with_dispatcher(HelloCommand);
// Run program
program.exec();
}
// Register wrapper type `Hello`, setting inner to `String`
pack!(Hello = String);
// Register chain to `ThisProgram`, handling logic from `HelloEntry`
#[chain]
fn parse_name(prev: HelloEntry) -> Next {
// Extract string from `HelloEntry` as argument
let name = prev.first().cloned().unwrap_or_else(|| "World".to_string());
// Build `Hello` type and route to renderer
Hello::new(name).to_render()
}
// Register renderer to `ThisProgram`, handling rendering of `Hello`
#[renderer]
fn render_hello_who(prev: Hello) {
// Print message
r_println!("Hello, {}!", *prev);
// Program ends here
}
// Generate program, default is `ThisProgram`
gen_program!();
