Subject: Re: Using a Regexp to find a Hash Key?


I sent an new one out right after this.
It appears that my public email key being attached to the email was  
wiping the body for some reason.

I sure could...

The hash is going to be real small. It would at most only have 3 or 4  
keys. The one I want has a prefix of an arbitrary string with any  
amount of number after it. I need to know if this key is present so  
that I can run a conditional block of code. It would be a bonus to  
get some match data back on that last series of digits in the regexp.

I would like to use something like this:

def foobar
   if hash.has_key?(/^foo_\d+$/)
     ...
   end
end

Meanwhile my code looks like this and I was pretty sure there might  
be a more terse solution.

def foobar
   unless params.reject{ |k, v| k !~ /^foo_\d+$/ }.empty?
     ...
   end
end
