Porting feedparser to Python 3

Posted 19 November 2010 in feedparser, programming, and python

Today I'm announcing I'm throwing my hat in the ring to port feedparser to Python 3. There's a ticket open regarding this at the feedparser bug tracker, but the person who's working on porting it appears to be writing Python 3 code instead of writing Python 2 code that the 2to3 tool can then convert.

I'm going to take the opposite approach -- which may not be workable -- and fix the Python 2 code so that it can be rewritten by the 2to3 tool. Here are my guiding principles:

  • Support Python 2.4 and up
  • Avoid rewriting code
  • Support BeautifulSoup and chardet later

I'll add other principles to this list as they occur to me.

I'm doing this because I've been unable to find any ongoing Python 3 porting efforts in the feedparser community. Sam Ruby toyed with it back in 2007, but I don't think his efforts have been incorporated back into the project in the intervening three years.

I'll have a github repository posted after my friend's wedding this weekend.
