Réf. : whitespace string only

[tad.bochan]

Anything wrong with

if "#{s}".chomp.strip.length == 0

or have I missed the point ?

Objet : whitespace string only


Hi!

What's the best way to test if a string only consists of whitespaces and
newlines?

best I could come up with is


class String

def is_whitespace_only?
strings_to_test = split("\n")
whitespace = /^\s+$/
is_whitespace_only = true
strings_to_test.each{ |str|
unless whitespace.match(str) or str.empty?
is_whitespace_only = false
break
end
}
is_whitespace_only
end

end

But somehow I think there should be a better way to do it. Any ideas?
Is it okay to add such methods to class String itself?

Any advices appreciated.

regards,
Henrik
