Question

I was wondering whether there is a trick to (easily) incorporate some python code into a moinmoin page, perhaps by adding some action. The idea is that something like

<<<
for j in [1,3,5]:
   print(i)
>>>

is displayed on the page as

1
3
5

Quick and dirty is ok, safety is not a concern, I would like to have this for a stand-alone, “desktop-mode” installation.

In your moinmoin instance go to

data/macro

Make sure that there’s an __init__.py with at least the following content:

from MoinMoin.util import pysupport

modules = pysupport.getPackageModules(__file__)

Then create your macro there:

touch PyShell.py

Use this as a template:

import StringIO
import sys

def macro_PyShell(macro, code):
  code_out = StringIO.StringIO()
  sys.stdout = code_out
  exec code.strip("'").strip('"')
  sys.stdout = sys.__stdout__
  return macro.request.formatter.text(code_out.getvalue())

In your wiki-pages you should now be able to call that macro with:

<<PyShell("for i in [1,2,3]:\n  print i")>>
