I'm using pyyaml 3.09 in Python 2.6.5 on Ubuntu 10.04 LTS.

I have a yaml file I used for configuration of a web server (tornado), and the section of my file causing issues looks like this:

RequestHandlers:
  # [ path, handler class, [whitelist] ]
   - [/stats, myapp.core.Stats, [127.0.0.1, 10.0.0.0/8]]
   - [r'/(?P<id>.*)', myapp.core.Foo, [127.0.0.1, 192.168.0.0/16]]
   - [/.*, myapp.core.MainHandler, []]

When this gets loaded, pyyaml yells at me. Here's a python interpreter session:

expected ',' or ']', but got '?'
  in "etc/myapp.yaml", line 35, column 10

============================================

Line 35 is:

   - [r'/(?P<id>.*)', myapp.core.Foo, [127.0.0.1, 192.168.0.0/16]]

I'm wondering why it's choking here. Disabling this line causes everything to work perfectly well. The question mark is a special case in YAML, but (I thought) only when it's accompanied by a space. I don't recall ever needing to escape anything inside of a yaml file, but I tried escaping the '?'. Not sure what to try next. If I double-quote like "r'/(?P<id>.*)'" then it'll be a double-quoted string on the other end of the load as well, which doesn't help me.

Clue hereby solicited.

In the PARSER API Synopsis example program there is a memory bug.

the while loop checks the type of the event.type but the event has already been deleted. the delete invalidates the event type under debian on my x86 system. to fix the bug, i had to introduce another integer variable to hold the type so that the loop can check that to know when to end.
