This is probably a silly question, but I’m wondering what the best way
is to scan a string for regular expression matches, and then link to it.
It would be great to do it in one line, like this:
<% text.sub!(/#[-'A-Za-z]+/, link_to($&, tweet.category_name))%>
But as the sub! has not completed, $& still refers to the old variable.
I suppose I can just find the text I will be matching ahead of time,
which would involve scanning the string twice, but there might be a
better way. Thoughts?
Thanks in advance!!
