markerlib
=========

Compile or interpret PEP 345 environment markers.

Usage::

    >>> import markerlib
    >>> marker = markerlib.compile("os.name == 'posix'")
    >>> marker(environment=markerlib.default_environment(),
               override={'os.name':'posix'})
    True
    >>> marker(environment=markerlib.default_environment(),
               override={'os.name':'nt'})
    False

The implementation uses the ast to compile environment markers as Python
statements with a limited set of allowed node types.



0.6.0
=====
- Allow _ where . was previously used ('os.name' -> 'os_name')

0.5.2
=====
- Restore 'as_function' bw/compat synonym for 'compile'

0.5.1
=====
- Include 'empty marker' heuristic in markerlib itself

0.5
===
- One final release until it's just a part of distribute

0.4
===
- Cache compiled marker functions with weakref.WeakValueDictionary
- Rename markerlib.as_function to markerlib.compile

0.3
===
- Might work on Python 2.5 (includes needed parts of the ast module from
  Python 2.6+)
- Include 100% test coverage, tox config file

0.1
===
- Initial version
