This might not be quite the question you\'re expecting! I don\'t want a regex that will match over line-breaks; instead, I want to write a long regex that, for readability,
Using %r with the x option is the prefered way to do this.
See this example from the github ruby style guide
regexp = %r{
start # some text
\s # white space char
(group) # first group
(?:alt1|alt2) # some alternation
end
}x
regexp.match? "start groupalt2end"
