Operators keyword

not

Keyword-style logical negation — equivalent to prefix !.

not(expr) negates a boolean expression. Affogato also supports the standard ! prefix operator; not(...) is an alternative readable form.

Affogato

    example.aff 
 guard not(users.isEmpty()) else {
    return "No users"
}
return users.get(0).name 

Generated Java

    Example.java 
 if (users.isEmpty()) {
    return "No users";
}
return users.get(0).getName();
