Regex for whitespace plus vertical bar

Robert La ferla

I am trying to quote arguments that have whitespace or a pipe (vertical
bar character = | ) in them. Why doesn't this work? What does work?



if arg.index(/[\s|]/)
...

end

| is a reserved character in regexes for disjunction, i.e. /a|b/
matches a or b, where a and b are arbitrary regexes.

This ought to work for your purposes, I think:

if arg.index(/[\s\|]/)

Seems to work for me:

$ irb
>> re=/[\s|]/
=> /[\s|]/
>> re.match('kldfslkd')
=> nil
>> re.match('df |sdf')
=> #<MatchData:0x4098995c>

Not in a character class.
