Hi!
I was writing some documentation about how to use a Python function, so I
decided to try the tangling feature. However, the result, when exported to PDF,
is unsatisfactory because the referenced code block is included twice -- first
in the original location, then again where I referenced it with
<<function-definition>>.
This is, of course, exactly what it needs to do to be able to execute the code
properly and show the result. But it doesn't look nice. Is there any way to
suppress the second printing inside the function-demo block?
If this isn't clear from the example below, I can provide examples of the
duplication 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./"
columns = len(data[0])
sizes = [0,]*columns
for row in data:
sizes = [max(x) for x in zip(sizes, [len(str(t)) for t in row])]
format = "| " + " | ".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
<<function-definition>>
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 |
