Subject: [ruby-talk:14448] How to do it the Ruby-way 2

Hi again,

I really like the way I can embed ruby code in strings using #{}.
This code works as expected:

 def a(name)
   print "<#{a.capitalize}>"
 end

but what if the pattern string isn't a constant but also provided with
that method, let's say:

 def a(pat, name)
   print pat
 end

This doesn't work anymore (of course).  Now, my solution is this:

 def a(pat, name)
  eval "print \"#{pat}\""
 end

But, I think, it's really ugly.  I'd like to use a pattern string read
in from an external file (from the trusted source) and then emit it
using all bindings currently available in that method.  How can this
be achieved?


bye
