Regular expression question?

Hi,

I want to translate the following Perl code into Ruby:

@captures = ($text =~ /company=(.+)/g)

Basically, the Perl version uses the g modifier to capture all
occurrence of the matches in () and put them into an array.

How do I do this in Ruby?

Thanks in advance.

Lei

captures = text.scan(/company=(.+)/)

Hope that helps.

match_data = text.match( /company=(.+)/ ) # see [0]

You can then treat your MatchData [1] object like an array and access matches like:

match_data[0]

Like so:
captures = string.scan(/company=(.+)/)

There will be an extra level of nesting so you may (or may not,
depending on how many groups your capturing) want to #flatten
captures.

Thank you very much for your help, guys!

I was surprised to see as many as 10 responses to my question.

That's what makes this Ruby newsgroup such a nice place.

captures = text.scan(/company=(.+)/)

As far as I see, `+' is greedy. Further, you don't need the
grouping. May this is better:

  captures = text.scan /company=\S+/

I think I misunderstood the question, but after rereading Jame's and Bertram's post I think I see what Lei Wu was looking for.

Hello there!

   I'm still new to Ruby and I was wondering if anyone know of a tutorial or procedure to prepare an installer for my Ruby applicacion. What I mean is a procedure or steps thay I should follow in order to make a full installer for my applicacion, that is, install Ruby compiler and all the needed libraries needed by my application. I think it would be a little troubling if the regular user need to install the Ruby compiler, FXRuby libraries, etc. on his/her own.

Thanks

Marcelo Panigua L.

If you are Windows you should take a look at Erik Veenstra's RubyScript2exe package.

I second that. I was using it earlier today, and it is quite the thing.
