NameError when Parsing an Email Address about markdown

[waylan]

How did you install markdown?

Was the 2to3 tool run on the source before installation?

If I recall correctly the import path for html.entities is one of the
things the 2to3 tool changes, which suggests to me that the 2to3 tool
wasn't run before installation.

Unfortunately, when we released Markdown 2.0.3 we had not yet set up
the installation so that the 2to3 tool would run automatically. This
has since been rectified and will be available in our next release.

Hope this helps. In the meantime, any workarounds would be appreciated.

This is Markdown 2.0.3 running on Python 3.2

The Code I'm using comes from EnigmaCurry's repo. It's supposedly nothing more than 2.0.3 run through 2to3. Should I do it differently until the next release?

On a side note: Perhaps you should remove the Python 3 tag from the PyPI entry until the usual installation works.

Thanks a lot for the prompt reply. It's a big help, since I have this version of Python Markdown running on a production server.

Ok, I just looked at the source (and EnigmaCurry's repo - interesting I didn't know it existed). The problem stems from a bug in the 2to3 tool which shipped with Python 3.0, which was the only version available when we shipped Markdown 2.0.3. That bug has since been fixed in Python 3.1. Unfortunately, the fix in the Python 3.1+ version of the 2to3 tool broke our workaround.

As we have already fixed this in our repo (next release coming soon), I'd suggest filing a bug report with EnigmaCurry to fix the import in markdown/inlinepatterns.py line 48. Probably something like this (untested):

+ import html
- if sys.version >= "3.0":
-     from html import entities as htmlentitydefs
- else:
-     import html.entities

Regarding our claim to support Python 3.0. That is correct, Markdown 2.0.3 only supports (the buggy) Python 3.0, not 3.1 or greater. Therefore, I will not be changing our note in that regard. However, our next release will not support Python 3.0 but will support Python3.1 or greater.

As there is no issue for use to fix here, I'm closing this.

This is excellent, thanks a lot Waylan.

Here's what I'm running now:

+ import html.entities
- if sys.version >= "3.0":
-     from html import entities as htmlentitydefs
- else:
-     import html.entities
