Python src blocks indent

Python src blocks indent

Hi,

I have a problem with Python src blocks indentation.
At the moment, I export IPython notebooks with ox-ipynb
(https://github.com/jkitchin/scimax/blob/master/ox-ipynb.el
from scimax by John Kitchin)

All the lines but the first one in src code blocks have 2 superfluous
leading spaces.
If I set
(setq org-edit-src-content-indentation 0)
then the code blocks are ok.

Any idea where to look for to track this problem further down ?

Best regards,

Fabrice

What do you mean by 2 superfluous leading spaces?
org-edit-src-content-indentation default value is 2. Do yo mean there
are now 4 spaces?

Could you show an ECM?

Hi,

I mean that in the Org buffer I have for example :

#+BEGIN_SRC ipython :session
  def fact(n):
      if n == 1:
          return 1
      else:
          return n * fact(n-1)
#+END_SRC

That is, there is a 2 spaces indentation of the whole code block, and the
code block is properly indented.
When I export it, I get :

def fact(n):
      if n == 1:
          return 1
      else:
          return n * fact(n-1)

in the IPython cell (basically, the notebook format is JSON and it is easy
to count those spaces in the code string in the JSON file)
and the 2 org-edit-src-content-indentation have been removed
only on the first line. The other ones have 6 or 10 spaces instead of 4 and
8.

Given that changing org-edit-src-content-indentation to 0 fixes this
problem, I wonder if there
is something wrong in the logic where this variable is used (only one place
in org-src).
But that could well be that it is not taken into account in places where it
should.

Regards,

Fabrice

FWIW I cannot reproduce it. You may want to debug
`org-export-unravel-code', `org-export-format-code' or
`org-export-format-code-default'.

Thanks Nicolas.

I should have looked closer at ox-ipynb since the problem is in there.
It should make use of  `org-export-unravel-code' and it doesn't. Instead
it trims leading white spaces from the src code.
I'll report it to the scimax github repository.
