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

Hi --

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

It seems to work OK:

irb(main):008:0> "abc|".index(/[\s|]/)
=> 3
irb(main):009:0> " abc".index(/[\s|]/)
=> 0

What results are you getting?

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

| 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\|]/)

end

Seems to work for me:

$ irb

re=/[\s|]/ => /[\s|]/
re.match('kldfslkd') => nil
re.match('df |sdf')

=> #<MatchData:0x4098995c>

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

| is a reserved character in regexes for disjunction,

Not in a character class.

"foo|bar" =~ /[|]/

=> 3
