So I found this little trick quite useful the yesterday…
If you want to use a regular expression matched variable to find and replace sections of text in a string more intelligently (I used to do this all the time in Perl, hence why I was looking for a Ruby equivalent) you can!
Here’s a rather contrived example but it gets the message accross.
puts text # => <a href=“#” class=“button”>click me</a><span class=“weee”>weee</span>
puts text # => <a href=“#” data-class=“button”>click me</a><span data-class=“weee”>weee</span>
The Perl equivalent to
\1 would be the
$1 matched variable…
