Turn your function(s) to a command line app. Inspires by Google's Python Fire.
sh
cargo add fire
```rust // Turn a single function to CLI app.
fn welcome() { println!("Welcome!"); }
// Turn mutilple functions to CLI app.
mod some_functions { pub fn hello(name: String, times: i32) { for _ in 0..times { println!("Hello, {name}!"); } }
pub fn bye() {
println!("Bye!");
}
}
fn main() { // 'Fire' the functions with command line arguments. fire::run!(); } ```
Now you can run your CLI app. By default the single function welcome should be called:
sh
$ cargo build
$ ./target/debug/app
Welcome!
The funtions in the mod should be called as sub-command with it's function name:
sh
$ cargo build
$ ./target/debug/app bye
Bye!
Funtions with arguments will receive the arguments from CLI app arguments, with format like --argname=argvalue:
sh
$ cargo build
$ ./target/debug/app hello --name='John Smith' --times=3
Hello, John Smith!
Hello, John Smith!
Hello, John Smith!
Fire will call .parse() on every argument, so all types which implements FromStr is supported.
