Multiple action application

```rust use seahorse::{color, App, Command, Context, Flag, FlagType}; use std::env;

fn main() { let args: Vec = env::args().collect(); let app = App::new() .name("multipleapp") .author(env!("CARGOPKGAUTHORS")) .description(env!("CARGOPKGDESCRIPTION")) .usage("multipleapp [command] [arg]") .version(env!("CARGOPKGVERSION")) .command(hello_command());

app.run(args);

}

fn helloaction(c: &Context) { let name = &c.args[0]; if c.boolflag("bye") { println!("Bye, {}", name); } else { println!("Hello, {}", name); }

match c.int_flag("age") {
    Some(age) => println!("{} is {} years old", name, age),
    None => println!("I don't know {}'s age", name),
}

}

fn hellocommand() -> Command { Command::new() .name("hello") .usage("multipleapp hello [name]") .action(helloaction) .flag(Flag::new("bye", "multipleapp hello [name] --bye", FlagType::Bool).alias("b")) .flag( Flag::new( "age", "multiple_app hello [name] --age [age]", FlagType::Int, ) .alias("a"), ) } ```

bash $ cargo run $ cargo run John --bye $ cargo run John --age 30 $ cargo run John -b -a 30 $ cargo run John --age=30

Single action application

```rust use seahorse::{color, App, Context, Flag, FlagType}; use std::env;

fn main() { let args: Vec = env::args().collect(); let app = App::new() .name("singleapp") .author(env!("CARGOPKGAUTHORS")) .description(env!("CARGOPKGDESCRIPTION")) .usage("singleapp [args]") .version(env!("CARGOPKGVERSION")) .action(action) .flag( Flag::new("bye", "single_app args --bye", FlagType::Bool) .alias("b") .alias("by"), );

app.run(args);

}

fn action(c: &Context) { let name = &c.args[0]; if c.bool_flag("bye") { println!("Bye, {:?}", name); } else { println!("Hello, {:?}", name); } }

```

bash $ cargo run $ cargo run Bob $ cargo run Bob --bye $ cargo run Bob -b
