CLI commands manager in Rust
Example
CommandBuilder
use commandor::prelude::*;
fn main() {
let manager = Manager::new(vec![
CommandBuilder::new("greet", |_, values: Vec<ArgumentValue>| {
for value in values {
// Each of `value.name` will be `--name` because
// there're no other arguments
println!("Hello, {}", value.value);
}
true
}).with_args(vec![
Default::new("--name", vec!["-n"], false)
]).build()
]);
match manager.execute(std::env::args().skip(1).collect()) {
Ok(executed) => println!("Executed: {}", executed),
Err(Error::TooFewArguments) => eprintln!("Arguments required"),
Err(Error::CommandNotFound(command)) => eprintln!("Command {} not found", command),
Err(Error::ArgumentRequired(argument)) => eprintln!("Argument {} required", argument)
}
}
Command trait
use commandor::prelude::*;

}

pub fn new() -> Box<Self> {
Box::new(Self {
args: vec![
Default::new("--name", vec!["-n"], false)
]
})
}
}
impl Command for Greet {
fn get_name(&self) -> &str {

}

&self.args
}
fn execute(&self, _: Vec<String>, values: Vec<ArgumentValue>) -> bool {
for value in values {
// Each of `value.name` will be `--name` because
// there're no other arguments
println!("Hello, {}", value.value);
}
true
}
}
