ezcli

Small and lightweight enough to be put into any CLI application quickly with no fuss. Just call a macro or two and it's up and running!

If you do want a more fleshed out CLI crate, you should check out clap.

flag

Command line argument for a boolean state. The flag! macro only requires a variable name. Once, invoked a variable of the passed name is created and it will check the command line for matching flags.

use ezcli::flag;

flag!(my_boolean);

if my_boolean { // "--my_boolean" exists in arguments
    // do stuff because flag is given
}

option

Command line argument for an optional parameter. The option! macro requires a variable name, like flag!, and makes it available to the scope. The value of the new variable will be a Some, unless it is not provided then it'll be None.

use ezcli::option;

option!(my_arg);

match my_arg {
    Some(x) => {}, // use x
    None => {}, // handle no value
}

named_flag

Command line argument mimicking the behaviour of the flag! macro. The only difference is that it accepts a Name, which will make short and long CLI names.

use ezcli::{named_flag, name::Name};

// --my-boolean and -b are accepted
named_flag!(my_boolean, Name::new("my-boolean", "b")); 

named_option

Like how the flag! and named_flag! macros are similar, this one is a nameable version of the option! macro.

use ezcli::{named_option, name::Name};

// --my-option and -o are accepted
named_option!(my_option, Name::new("my-option", "o"));
