[IPython-dev] Anyone encountering IndentationError issues in the notebook?
Wed Aug 22 19:40:23 CDT 2012
Just confirmed, it is a problem of the latest codemirror (2.30.0).
Previous version (that is still bundled with notebook) don't have that
Can be reproduced by:
1. open http://codemirror.net/mode/python/index.html
2. go to a first line, type <tab>print<enter>print<enter>
It would result in: a tab in front of a first print statement; 4 spaces in
front of the second.
This would result in IndentationError in python. And [I take it] ipython
just doesnt't show line number in this case.
