Subject: Babel CALL no longer produces HTML output
Date: Sat, 23 Jul 2016 15:14:47 +0300 [thread overview]
Message-ID: <87r3akzh3c.fsf@iki.fi> (raw)
Greetings.
The Org example below used to work correctly when exported as HTML until
I pulled a newer version of Org from git. I am first going to include
the example here, and then explain the reasoning behind its structure.
=======================================================================
* Example
This call here produced HTML output when exported as HTML until the
newer versions of Org. Now it produces no HTML output whatsoever.
#+CALL: rekursio-pystyviivat[:noweb yes]() :results html
The following code blocks still work as expected.
#+NAME: rekursio-pystyviivat-runko
#+BEGIN_SRC processing :exports none
if (viivoja == 0)
return;
line (x, 0, x, korkeus);
piirraPystyviivat (viivoja - 1, x + 10, 0.9 * korkeus);
#+END_SRC
#+NAME: rekursio-pystyviivat
#+BEGIN_SRC processing :exports code :noweb no
void piirraPystyviivat (int viivoja, float x, float korkeus)
{
<<rekursio-pystyviivat-runko>>
}
void setup ()
{
size (600, 400);
noLoop ();
}
void draw ()
{
piirraPystyviivat (50, 10, 350);
}
#+END_SRC
=======================================================================
In the example above I am playing with noweb to produce the following
_excellent_ teaching effect:
- the last Babel code block is what a student sees
- the student is supposed to replace
<<rekursio-pystyviivat-runko>>
with correct code, in this case the body of a recursive function
- the last block has ":noweb no" so that the missing part is not
replaced by the correct solution
- in the CALL, however, noweb is set to yes so that noweb replacement is
done, and the first block produces the correct output (in the case of
Processing language, this is a picture)
I use this structure quite a bit in my material, which is finished
except for layout formatting. So I am going to be in trouble if I can no
longer get the logic to work in Org.
