I'm just getting started with Sinatra. I'm running Ruby 1.9.2 on Ubuntu. After my first issue, I've run into another one:
When I follow the simple sample application instructions at sinatra.rubyforge.org/doc/, I modify my source file, but the changes aren't apparent until I restart Sinatra - even though the tutorial mentions there is no need to restart.
How can I edit my source and view the results without having to restart Sinatra every time?
