Yes, that was a typo, I actually used that hook (as you wrote it). Furthermore I forgot to mention, that the second code snippet, the one in file B, is named: ==== File b.org ==== [Text …] #+NAME: file-b-method-foo #+BEGIN_SRC python :exports none def foo(self): print(“bar”) #+END I even tried to use CUSTOM_ID (and ID as well), but babel does not seem to resolve links as [[file:b.org::file-b-method-foo]] when tangling.
