rspec users - Aug 2008 - embedding variable in a regex

Given /a (PROGRAM|PROGRAMMES) title of ''$title''/ do |title|
    ....
 end

 Could anyone give me the correct syntax for embedding this variable in a regex?

You''ll need to create a sub-expression capturing the title.
Sub-expressions are denoted in a regular expression with
parenthesizes. You already have one in your with (PROGRAM|PROGRAMMES).
If your regex matched a given step the title would be either PROGRAM
or PROGRAMMES depending on what the step description looked like.

You probably want to use a non-matching sub-expression for
PROGRAM|PROGRAMMES so it doesn''t get captured (and thus passed in as a
block parameter).

Try this:

  Given /a (?:PROGRAM|PROGRAMMES) title of ''([^'']+)''/
do |title|
  end

Which should match the step with the name

   Given "a PROGRAM title of ''foo bar baz thingy
majoo''"
