i am not talking about the delimiter
your pattern is:
your test string is:
the first character of your pattern is a "/" and your first character of
your test string is an "f". They do not match. The regex engine stops
after checking the first character. This has nothing to do with
greediness or end of line anchors, but only with the first character
maybe what you wanted for your test string was
This test string would then require your end of line anchor. Because the
end of line character does not match the "b" the engine stops. No match.
This is consistent with the findings of others who replied to you.
Perhaps your regex engine has a different syntax for anchors. For
example if your engine was seeing the carrot as a an exclusion operator
rather than being a beginning of line anchor and it was also, idk,
ignoring the dollar sign as your end of line anchor then you would get a
match. But otherwise I would recommend you copy/paste the example you
provided and confirm that you still get a match. Then i would confirm
your regex engine's anchor syntax. Then, recompile your software....
