Hello, how to better write that : self.ident = self.ident[/0-9*/]

I'm pretty sure there is a String method that would keep only the first
match of the regex but I didn't found it in the String doc reference

ri String#slice, ri String#slice!

Thanks



Fine ! Thanks... About the same topic (Strings) I wonder how to replace
"REF:90 REFERAL".gsub!('REF:','')
by something else

What something else? Please say specifically what you want to accomplish.
Post an example string before you apply your desired remedy, and after.


I tried with .delete but

"REF:90 REFERAL".delete!("REF:") delete every R, E or F char in the string


How to use delete ?

You are asking how to apply a particular solution, but without first stating
a problem. Maybe the problem is better solved using a different method.
