Subject: Re: Valid email address from CGI input?

Julian,

Sorry to look dumb I am kind of new to Ruby.  I move quickly with all the
OOP aspects of it, coming from a Java background, but the lower level
stuff, especially regex is a learning curve.

When I use this code ...

def email_valid?(email_address)
    email_address =~
/^([a-zA-Z0-9&_?\/`!
#*$^%=~{}+'-]+|"([\x00-\x0C\x0E-\x21\x23-\x5B\x5D-\x7F]|\\[\x00-\x7F])*"
(\.([a-zA-Z0-9&_?\/`!
#*$^%=~{}+'-]+|"([\x00-x0C\x0E-\x21\x23-\x5B\x5D-\x7F]
\\[\x00-\x7F])*"))*@([a-zA-Z0-9&_?\/`!|#*$^%=~{}+'-]+
\[([\x00-\x0C\x0E-\x5A\x5E-\x7F]|\\[\x00-\x7F])*\])(\.([a-zA-Z0-9&_?\/`!
#*$^%=~{}+'-]+|\[([\x00-\x0C\x0E-\x5A\x5E-\x7F]|\\[\x00-\x7F])*\]))*$/
end

in the actual code file I have the regex in one long line such as

def email_valid?(email_address)
    email_address =~ /^([a-zA-Z0-9&_?\/`!|#*$^ and all the rest of the regex
end

email_address is null after every evaluation both valid and invalid.  What
am I missing?

Is there a way in Ruby Syntax to split the regex and have Ruby ignore the
<cr>?

Thanks for your continued help
john
