In my understanding of PyRex? (which, I admit, is fairly limited), it is a tool that converts PyRex? code into C (.c, .h, etc.) and Python code. Can't this conversion be done ahead of time when assembling a distribution, so that you don't need PyRex? on the install side? (Same as running lex or yacc etc. at distribution time instead of install time.) Or is there something more subtle going on during installation that this is actually necessary?

Reducing the barrier to installation should make the "fast PyYAML solution" (PyYAML + libyaml) more widely available.

With the latest PyYAML (3.04):

$ python
Python 2.4.4 (#2, Oct 19 2006, 23:03:48)

>>> import yaml

Traceback (most recent call last):

    return self.construct_document(self.get_node())
  File "/usr/local//lib/python2.4/site-packages/yaml/composer.py", line 23, in get_node
    return self.compose_document()
  File "/usr/local//lib/python2.4/site-packages/yaml/composer.py", line 35, in compose_document
    node = self.compose_node(None, None)
  File "/usr/local//lib/python2.4/site-packages/yaml/composer.py", line 52, in compose_node
    anchor = event.anchor
AttributeError: 'NoneType' object has no attribute 'anchor'
>>> 

I think this is a bug - at least it should raise a yaml.scanner.ScannerError?, like yaml.load("'") does, and then it can be easily catched as a malformed stream. Right now, it's hard to deal with this.

Thanks, Iustin

Hi, I have a patch that makes PyYAML use types module instead of hand crafted entities and type(). The motivation is that it silences some PyDev? error complains, like methods not having self parameter and such.
