Most common string manipulations for a webapp

Because every time I create a new webapp, I think about how I should process user-generated content. Should convert urls to links and images? Should I allow certain tags? Should I convert all new lines to <br/> tags? Well, now all that is as simple as calling a single method.

1. gem install string_master
2. gem install ultraviolet (optional, if you want code highliting feature, only works in ruby 1.8.x)

Say you got this string

s = "Hello, glorious owner of the website\nI hope <b>you</b> like my message"

Oh my god, what am I going to do with it?

# try this
s.prep.newlines_to_br.html_escape
# which is equivalent to this (block notation)
s.prep { |s| s.newlines_to_br; s.html_escape }

Result:

Hello, glorious owner of the website
I hope <you> like my message

Fuck yeah.
