Re: [O] [Proposal] Source Blocks with Post-Extensions

[Dmitrii Korobeinikov]

Thank you!

That's a handy technique and it does help.

As I understand, there's no way to extend that to multiple lines?

One-liners for tests are enough sometimes, but not always.

For those cases, it is cumbersome to split as well.

It looks like you want the :epilogue header argument. See inline.

Equivalently, you could run this:

#+NAME: square
#+BEGIN_SRC python :epilogue  return square(5)
    square = lambda x: x * x
#+END_SRC

With my version of `square`, the epilogue is not included.

So it works as you want it to.

HTH,
