是否可以更改红宝石评论符号？

Question

So, to comment in ruby, you need the # symbol.

# this is some comments

Which is fine, but for multi-line comments, ruby has an ugly system.

=begin
    comment line 1
    comment line 2
=end

I have search around the internet and found nothing on the topic. I want to see if I am able to change that format to something better by defining my own commenting system. Such as:

/*
    comment line 1
    comment line 2
*/

I want to see if I can do something like

def /*
  define comment logic
end
def */
  define comment logic
end

Just something to that effect. I don't need to replace to current one, just want to see how I can define my own. I'm not looking to rewrite ruby. I just want to see if there is something simple that i can do whenever I write ruby. As an example, if I want to add a method to the String class, I can do

class String
    def new_method
        # some new functionality.
    end
end

I want to see if I can do something like that for comments.

Answer 1

Nobody uses multi-line syntax. People do this instead:

# comment line 1
# comment line 2

Most editors have a shortcut that allows one to comment in multiple lines easily. You will get used to it!

Answer 2

A comment says "Ruby stops here, what follows is outside of Ruby". Therefore, it should be pretty obvious, that you cannot change what a comment is from inside Ruby.

But there's another problem with your proposed syntax: it is already valid Ruby. It's a multi-line Regexp literal. (Yes, it is semantically invalid, but it is a syntactically valid Regexp literal.)
