When I see some text that matches my pattern, I want to create a link to an external site using RedCloth that has a query link for it.
If I have something like:
Text 123 1234 12345
When I see that I want to replace it with:
"Text 123 1234 12345":http://site.com/query?value=Text%20123%201234%2012345
If I let it keep the spaces, RedCloth won't notice this as a link correctly.
Here is where I am at:
s = "this is a string which has Text 123 1234 12345 "
s = s.s.gsub(/(Text \d+ \d+ \d+)/,'"\1":http://site.com/query?value=\1'
=> "Text 123 1234 12345":http://site.com/query?value=Text 123 1234 12345"
The probem is that RedCloth stops parsing after:
"Text 123 1234 12345":http://site.com/query?value=Text
So I really need:
"Text 123 1234 12345":http://site.com/query?value=Text%20123%201234%2012345"
Is there a way I can mess with \1 in the right hand side of gsub, such that I could get the following? If not, what's the best way to do this?
Ok, thanks to the comment by Narfanator I found the following: "$1 and \1 in Ruby".
The solutions was super easy:
s = "this is a string which has Text 123 1234 12345 "
s = s.s.gsub(/(Text \d+ \d+ \d+)/){|x| "\"" + x + "\":https://site.com/query?value=" + CGI::escape(x)}
