Hi all,
I'm trying my hand at scripting cgi in ruby. At the same time I'm
looking at Rails. So far I love ruby. Still reserving comments on
Rails. I have a question though. When coding a cgi script, is it
possible to have methods as I would say in a n my_app.rb or rails app?
Below is a script I'm working on to provide a web interface to our
syslog servers logs for our tech support dept. I would like to DRY this
up a bit. I'm repeating entirely too much code. I would welcome not
only a response to my question, but any other suggestions/criticism to
aid me in my learning process. Thank you very much.
