Comment 3 for bug 315706

Well, if you are embedding IPython yourselves, you can try doing something like (this is code for trunk, the imports will be slightly different for 0.10):

import re
from IPython.core import prefilter

prefilter.re_exclude_auto = re.compile('your regexp here')

# rest of your code...

Let me know if this works for you. If it does what you need OK, you have a workaround for now, and I'll then refactor the code to have an official API for this.

I've reopened the bug so it stays tracked.
