Class diagram : manually separate attributes and methods

[tamdaz]

Proposal

My suggestion is to use a horizontal line to manually separate attributes and functions.

Reason

By default, this library separates attributes from methods using parentheses. However, in strongly typed programming languages, types can sometimes contain parentheses to make it explicit. For Mermaid, it thought it was a method, whereas it's actually an attribute.

Example

classDiagram
class Circle {
    -@radius : Array(Int32)
    ----------------------------
    #initialize(radius : Array(Int32))
    +add_number(number : Int32) self
}

This example shows a class with an attribute and methods. A horizontal line (which is a sequence of - characters) is placed between the two. To ensure that a horizontal line works, at least 3 or 4 - characters must be used.

For information, the generic of the @numbers attribute (instance var) is surrounded by parantheses, not by < and >. This type refers to the Crystal programming language.
