Ruby on Rails HTML link helper

April 20, 2008

Sometimes you might want to link up any html links from a string of text:

def make_links( str )
  regex = Regexp.new '(https?:\/\/([-\w\.]+)+(:\d+)?(\/([\w\/_\.]*(\?\S+)?)?)?)'
  str.gsub( regex, '<a href="\1">\1</a>' )
end

Book Recommendation:

The C++ Programming Language is the defacto-standard for C++. Written by Bjarne Stroustrup, the creator of C++, this book presents the full specification for the C++ language and standard library, a spec that will soon become the joint ISO/ANSI C++ standard. This is not really a C++ language tutorial but instead provides a clear presentation of all its elements. It is impossible to overstate the importance of this book for anyone who is serious about using C++. This book is in no way thin on material for the intermediate to advanced C++ software engineer.
