Dear list,
Is it possible to include sections of an org document while tangling.
I have in mind something like the following:
* Some section
<<doc>>
This is an introduction. We're going to write some code that implements (a
finite version of) the formula
\[
f(x) = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \ldots + \frac{x^n}{n!} + \ldots
\]
Here's some background about the exponential function.
#+BEGIN_SRC python :tangle myfunction.py
from math import factorial
def f(x,n):
"""<<doc>>"""
y = 0
for i in range(n+1):
y = y + x**i/factorial(i)
return y
#+END_SRC
The idea would be that when I export this to HTML, I get a nice literate
programming math jax'd section introduction that explains what the
function is doing. Then, when I tangle to generate the python file, the
org section introduction would be included as the python docstring of
the function.
This would be really useful, because currently I find myself repeating
information when I use org for literate programming. First, I explain
what a python function is doing in the org file, but then I also want to
include a docstring in the tangled output that basically contains the
same information as the org file.
Thank you,
David
