It’s always better to make your regular expression more specific e.g. searching for a word at the start of line and searching for a word in the line can make big performance difference, if majority of traffic is for unmatched input.

Bernardo, some characters got stripped out in your comment, and the quotes got changed to curly quotes. It should be

1	/(?<name>\w+) (?<age>\d+)/ =~ "David 30"

Hi, nice post! It’s worth pointing out, I think, that you can also get named capture groups with the =~ notation:

/(?<name>\w+) (?<age>\d+)/ =~ "David 30"

name

=> "David"

age

=> "30"

As far as I know it only works this way around, and not this way:

1	"David 30" =~ /(?<name>\w+) (?<age>\d+)/
