Greetings.
I would appreciate help in fixing a Babel indentation problem. I
recently added support for Processing programming language in Babel. It
is working very nicely except for an indentation problem I ran into.
The Org snippet below shows two basically indentical code blocks, one in
C and the other in Processing. When I edit the code blocks with "C-c '"
and return to the Org file, the C code indents correctly, while the
Processing code doesn't. To be more specific, one line doesn't, and the
line is indicated in the file.
# ------------------------------------------------------------------
* Example with C
#+BEGIN_SRC c
#include <stdlib.h>
int main (int argc, char* argv[])
{
int a = 0, b = 0;
while (a == 0)
{
if (a == 0)
{
if (b == 0)
a++; /* this line indents correctly */
}
}
exit (0);
}
#+END_SRC
* Example with Processing
#+BEGIN_SRC processing
size (400, 400);
int a = 0, b = 0;
while (a == 0)
{
if (a == 0)
{
if (b == 0)
a++; // while this one doesn't
}
}
#+END_SRC
# ------------------------------------------------------------------
Now when I edit the Processing code with "C-c '", go to the problematic
line and press tab, the line is indented correctly:
----------------------------------------------------------------------
size (400, 400);
int a = 0, b = 0;
while (a == 0)
{
if (a == 0)
{
if (b == 0)
a++; // while this one doesn't
}
}
----------------------------------------------------------------------
So the problem is not in indentation in Processing mode itself, but the
error appears upon return from editing. This suggests that the issue
is in the communication between the editing mode and Org mode. As you
can see, I have different indentation settings for C and Processing, so
that might be one thing that makes the difference appear.
The incorrect indentation carries over to, for example, exported files.
Any ideas on how I would start fixing this?

I think it is because you are using TABs to indent instead of spaces and
therefore the indentation doesn't look right in the org mode view. You
can tell emacs to not use tabs to indent and I think this will sort your
problem out.

Yes! Problem solved with
(setq-default indent-tabs-mode nil)
Thank you very much!
