Macros

In Crabby, the macro is used for defining macros, it is a code, that writes code which is a form of Metaprogramming just like the decorators. This can be done with the macro keyword, following with the ! (exclamation mark) symbol for calling the macro.

Example:

macro repeat {
    (value, count) => {
        for i in 0..count {
            print(value)
        }
    }
}

pub def bar() {
    repeat!("Hello, World!", 10)
}
