Hi,
I am looking at a new strategy to capture stderr and exceptions in python code blocks. Right now exceptions are not captured in the output, and neither is stderr.
I made a little sandbox module that captures stdout, stderr, and exceptions and then prints them all to stdout with some minor formatting. Here is an example.
Say test.py has this content
#+BEGIN_SRC python
print 'hello'
print 4 + 6
import sys
print >>sys.stderr, 'message to stderr'
raise Exception('baboom')
#+END_SRC
When I use the sandbox, I get all the output on stdout like this.
#+BEGIN_SRC sh
python -m sandbox < test.py
# or cat test.py | python -m sandbox
#+END_SRC
#+RESULTS:
#+begin_example
--------------------------------------------------------------
hello
10
--------------------------------------------------------------
stderr:
message to stderr
--------------------------------------------------------------
Traceback (most recent call last):
File "/home/jkitchin/Dropbox/pycse/pycse/sandbox/sandbox.py", line 16, in <module>
exec(content, ns_globals, ns_locals)
File "<string>", line 10, in <module>
Exception: baboom
#+end_example
So, I was wondering how to get this to happen in org-mode on a regular python block. I think it could work if I could define a custom interpreter for a particular block, e.g. python-sandbox that takes the codeblock on stdin.
