Ruby: make plain text links clickable

If you have some plain text containing links and want to turn them into actual hyperlinks, Ruby's URI module has a method to generate a regular expression for finding them. Combined with our old friend String#gsub, this makes the task almost too easy:

text.gsub(URI.regexp, '<a href="\0">\0</a>')

If you are using Rails you may want to use simple_format to also conveniently convert newlines into line breaks and paragraphs:

simple_format(text).gsub(URI.regexp, '<a href="\0">\0</a>').html_safe

Nice catch. But you know what, it works badly if the string has something like
"Check my new post: DOGS in "
When using " {something}: " it recognizes it like a link as well.
