Understanding というのは after a dash?

The teacher 姫子 is addressing the students.

How should I understand the というのは in this context? And can I translate
毎年言われているだろうから深くは掘り下げん as "You students are told not to have too much fun every
year, so I will not delve deeper"? Is anything wrong with the translation?




The dashes indicate a pause before the character speaks.

As for the translation, your understanding is fine. というのは quotes the preceding
羽目を外さないように= _Don't have too much fun_ , in the way similar to _which is..._ in
English. So the more literal translation may be: _...which I guess is what you
are told every year, so I don't say more about it (=how you shouldn't have too
much fun)_.
