I’m not a pro in using Regex and can’t figure out why the following behaviour happens, especially if we take into account the difference of matching in Javascript, Java, and Ruby (that’s why I’m a kind of stuck).
So I’d like to split a String input on one of the below characters:
- spaces
- underscores
- comma
- colon
- punctuation
- special characters
So I have the following code snippet in iex session:
String.split("testing, one, two car : carpet as java : javascript!!&@$%^& co-operation one_two 1 2", ~r/[\W-[_]|:]+/u, trim: true)
that returns:
["testing", "one", "two", "car", "carpet", "as", "java", "javascript", "co",
"operation", "one", "two", "1", "2"]
I had to substract underscore symbol from \W(any “non-word” character) as it includes it (a-zA-Z_).
As you see, there is still a problem with matching the hyphen in co-operation word.
Whatever I try, whenever I put - in the above regex, nothing works, - it just breaks the previously matching cases.
Any ideas? Thank you.
