Regex: Capture an overlapping pattern

Question

I would want to capture all combinations of my pattern even if it is overlapped.

Sample text

pack my box 12345 pack my box 67890 blah blah far away another pack my box 99999 is present

Expected output

Match 1 - pack my box 12345 pack my
Match 2 - pack my box 67890 blah bl
Match 3 - pack my box 99999 is pres

Regex

/pack my box.{0,14}/

However, Match 2 is not outputted since it is overlapping with 1.

Obviously, this is an SSCCE version of a bigger problem.

It would work for `scan`, but would not work for `gsub`. The matches are actually empty. – Aleksei Matiushkin Sep 12 '18 at 15:08
Ah, thanks for the info. I was actually looking for a solution for `scan`. Good to know that it will not work `gsub` – bragboy Sep 12 '18 at 15:11
