I don't know. Ripper's output looks like a mess to me when compared to  
RubyParser:

s(:call, s(:call, nil, :a, s(:arglist)), :[], s(:arglist, s(:lit, 1)))

how to pass a variable to a method in an existing class?

Hi,

I am a new ruby user and I want to add a function to an existing class.
I googled the answer and found part of the solution. All findings on the
web adding a new method without a variable. In my case I want to use the
string as a variable. Here is what I want to do:
class String

def convert(x)
#code to convert the x
x.upcase
end
end

What I want is in the irb I can use the new method in the way as:

"a".convert

This will convert a to upper case. However, it does not take the "a" as
the input variable and generating error
ArgumentError: wrong number of arguments (0 for 1)

How do I acheive what I want?

Thanks

Frank

Re: how to pass a variable to a method in an existing class?

"self" is a pointer to an actual element. So if you write:
class String
  def convert
    self.upcase
  end
end

It'll be perfectly fine.

Martin

Re: how to pass a variable to a method in an existing class?

--Marcin's way is perfect; but there is something we don't understand
about your requirement:

"...I want to use the string as a variable

def convert(x)
> #code to convert the x
..."

then..."in the irb I can use the new method in the way as:
>
> "a".convert <---what's happened to ur variable x???

Best Regards,

Re: how to pass a variable to a method in an existing class?

Martin's answer solved my problem.

Basically, I wrote my own method and want to add to the existing class 
and expected that the "string".convert will pass the "string" to the 
method. However, I could not find the solution to let the convert method 
takes the "string" as input. the self pointer solved the issue.

Thanks

Frank

I got a lot of help from the IRC channel, and Steve mentioned just recently
that he's still developing it (
http://blog.rubybestpractices.com/posts/gregory/050-issues-18-testing-dogma.html#comment-268721639).
Shoes is definitely not abandoned.

Biggest complaint I had was difficulty getting feedback (when I used Shoes,
it would swallow errors, as opposed to Limelight, which would report them on
stdout) IDK if its still set up that way, or if one of the other colours of
shoes doesn't do that. Second biggest is that IDK how you'd test most of
that stuff.

Re: newbie question

You will need a framework like rails or sinatra to do web "stuff". I
recommend taking a look at rails, there are a lot of good tutorials online
to help get you started.
