python-markdown loads but does not change rendering about jupyter_contrib_nbextensions HOT 14 CLOSED

What version of IPython are you using ?
Make sure you select the right branch (2.x or master) of this repository.

from jupyter_contrib_nbextensions.

Ah-ha. Right you are, juhasch. I read those installation instructions as referring to which python version (2.x or 3.x) you're using, rather than which IPython version. Perhaps this could be bolded in the installation instructions to prevent future confusion?

from jupyter_contrib_nbextensions.

So I've now downloaded and installed the 2.x version of python-markdown and I get the same behaviour. Not sure where I'm going wrong, sorry.

from jupyter_contrib_nbextensions.

Can you look at the Javascript console output in the Browser, are there any error messages ?

from jupyter_contrib_nbextensions.

The javascript console reports Loaded extension: python-markdown when I run IPython.load_extensions('python-markdown'). When I render the markdown cell there is no additional console output.

Have you tried clearing your browser cache or opening a private window ?
Somtimes Javascript caching is too agressive in the Browser.

from jupyter_contrib_nbextensions.

Same behaviour after clearing cache, and also tried opening in a private window. Also tried the same thing in Chrome and I get the same behaviour. The javascript console reports Loaded extension: python-markdown, then no further output.

from jupyter_contrib_nbextensions.

You can try this version that does some logging to the Javascript console:
https://gist.github.com/c37408a0d79156f28c17.git
You should see messages like:
PyMD: kernel started
PyMD: render
PyMD: execute
If not, the extension does not execute properly.

from jupyter_contrib_nbextensions.

I had the same problem, but this version you just posted seems to work for me.

from jupyter_contrib_nbextensions.

I don't get any additional console output, unfortunately.

from jupyter_contrib_nbextensions.

So which version of IPython are you using exactly ?
Do you see the correct notebook extension file if you go to http://127.0.0.1:8888/nbextensions/python-markdown.js ?
(assuming your notebook server is at 127.0.0.1:8888)

from jupyter_contrib_nbextensions.

Actually, the gist code now works for me (sorry!). Before I had shut down the notebook and re-opened it, showing the same behaviour as the 2.x code. Since then I've shut down the notebook server. I just restarted the server, and I now get the additional console output

Loaded extension: python-markdown
PyMD: render
PyMD: execute
PyMD: callback

and the rendering works. So it's something about the 2.x version that changes in the gist you posted.

The result of IPython.version_info is (2, 2, 0, '').

Thanks for the feedback. I have updated the extension, so the GitHub version should work, too.

from jupyter_contrib_nbextensions.

Great, thanks @juhasch. I can confirm that the GitHub version now works.
