I was writing some documentation about how to use a Python function, so I d= ecided to try the tangling feature. However, the result, when exported to P= DF, is unsatisfactory because the referenced code block is included twice -= - first in the original location, then again where I referenced it with <>.=20 This is, of course, exactly what it needs to do to be able to execute the c= ode properly and show the result. But it doesn't look nice. Is there any wa= y to suppress the second printing inside the function-demo block? =20 If this isn't clear from the example below, I can provide examples of the d= uplication in action as well as what I'd like the output to look like. Thanks very much! Example file: #+TITLE: Tangle Test #+LANGUAGE: en #+OPTIONS: H:3 num:nil toc:nil \n:nil @:t ::t |:t ^:nil -:t f:t *:t <:t #+OPTIONS: TeX:t LaTeX:t skip:nil d:nil todo:t pri:nil tags:not-in-toc * Tangled Code I want to show the definition of a function first: #+name: function-definition #+begin_src python :tangle yes :exports code def entable(data): if not data: return "/No data./" =20 columns =3D len(data[0]) sizes =3D [0,]*columns for row in data: sizes =3D [max(x) for x in zip(sizes, [len(str(t)) for t in row= ])] =20 format =3D "| " + " | ".join(["%%%ds" % x for x in sizes])+" |" return "\n".join([format % tuple(row) for row in data]) #+end_src Now I want to show a demonstration of how the function might be called. I need the function to be included so that demonstration code can be executed, but I don't want to include the function definition twice: #+name: function-demo #+begin_src python :tangle yes :exports both :noweb yes :results output <> =20 print entable([["One", 2, 3],["Four", 5, 6], ["Seven", 8, 9]]) #+end_src Which gives us this result: #+results: function-demo : | One | 2 | 3 | : | Four | 5 | 6 | : | Seven | 8 | 9 |
