I did add this line:
ret[:HOSTNAME] = hostname = "(?:[a-zA-Z0-9\\-._]|%\\h\\h)+"

But still getting the error
URI::InvalidURIError: the scheme http does not accept registry part: 
auto_diversen.marktplaza.nl:80 (or bad hostname?)

When executing:
URI::Parser.new.parse(url).open

Are you sure I only need to monkey-patch URI::Parser#initialize_pattern 
?
