I'm having trouble with getting python source=code blocks to export to
LaTeX properly. I've figured out what's going wrong: the exporter is
inserting tab characters on lines with 2 or more indentation levels in
python. If I use org to export to .tex first, and then untabify the
.tex files, the indent levels are preserved (assuming the tabs
correctly lined up with the corresponding python in the first place,
which many times they don't).
Here's a test.org file:
* Heading 1
LaTeX export does not work on python src blocks with more than 2
levels of indentation.
For example (4 spaces per indent level, not tabs):
#+BEGIN_SRC python -n
def foo(x):
print("Hi: %s" % x)
if x == "James":
print("James is the best!")
else:
return x
#+END_SRC
The above should be indented properly. But it isn't. The resulting
.tex file has tabs on the second indent level lines and the tab
doesn't even line up with the 4 spaces per tab either. Any ideas how
to get rid of this? If I run a =C-x h M-x untabify= on the .tex file,
then it exports just fine. But I don't /want/ to do that each and
every time I export my org files.
Here's the verbatim portion of the generated LaTeX source:
#+BEGIN_SRC latex -n
\begin{verbatim}
1 def foo(x):
2 print("Hi: %s" % x)
3 if x == "James":
4 print("James is the best!")
5 else:
6 return x
\end{verbatim}
#+END_SRC
Note: lines 4 and 6 in the =\begin{verbatim}= blocks.
Line 4 is "4[space][space][tab]print("James...")" How do I get org to export
with all spaces and no tabs for verbatims in LaTeX?

Try to set `org-src-preserve-indentation' to a non-nil value (on a very
recent Org) or add a "-i" flag to you source block:
#+BEGIN_SRC python -n -i
...
#+END_SRC
This should prevent Org from touching indentation within the block.

Thank you! That worked perfectly. Is '-i' not in the docs?

I think it was very recently added (i.e. yesterday) due to this thread
about a very similar (same) issue:
- http://www.mail-archive.com/emacs-orgmode@gnu.org/msg81203.html
I'd love to update Worg/documentation to include it... out of
curiosity, where were you looking for it to be documented? That way, I
can add it to the most intuitive/popular location.
Thanks,
John

Again (as for `org-src-fontify-natively'), shouldn't this be true by
default?
Best regards,

I don't know for other people, but the default value is good for me.

i can't seem to find the -i flag in the manual. perhaps i used the
wrong search term? i looked in literal examples and in working with
source code. i am using maint.
also:
- is there another flag to set org-src-preserve-indentation to nil?
- will -i still work if org-src.preserve-indentation is t?
thanks.
i'd be happy with a fixed 2-space indentation, but that is not
possible in current org. i find org-src-preserve-indentation to cause
more issues than it improves, so i am going to transition to it being
t, which feels safer even though it is not the default and does not
have the 2 spaces.

Indeed. It doesn't appear in the manual.
I don't use it. Maybe Someone using it can provide a patch for it.

No.

FWIW, I'm happy with `org-src-preserve-indentation' set to nil.
Anyway, if you think `org-src-preserve-indentation' needs improvement,
please provide a description (or ECM) of what you expect it to do.

I added one sentence about -i in the manual.
