"""Utility to compare (NumPy) version strings.

The NumpyVersion class allows properly comparing numpy version strings.
The LooseVersion and StrictVersion classes that distutils provides don't
work; they don't recognize anything like alpha/beta/rc/dev versions.

"""

class NumpyVersion:
    """Parse and compare numpy version strings.

NumPy has the following versioning scheme (numbers given are examples; they
    can be > 9 in principle):

- Released version: '1.8.0', '1.8.1', etc.
    - Alpha: '1.8.0a1', '1.8.0a2', etc.
    - Beta: '1.8.0b1', '1.8.0b2', etc.
    - Release candidates: '1.8.0rc1', '1.8.0rc2', etc.
    - Development versions: '1.8.0.dev-f1234afa' (git commit hash appended)
    - Development versions after a1: '1.8.0a1.dev-f1234afa',
                                     '1.8.0b2.dev-f1234afa',
                                     '1.8.1rc1.dev-f1234afa', etc.
    - Development versions (no git hash available): '1.8.0.dev-Unknown'

Comparing needs to be done against a valid version string or other
    `NumpyVersion` instance. Note that all development versions of the same
    (pre-)release compare equal.

Parameters
    ----------
    vstring : str
        NumPy version string (``np.__version__``).

Examples
    --------
    >>> from numpy.lib import NumpyVersion
    >>> if NumpyVersion(np.__version__) < '1.7.0':
    ...     print('skip')
    >>> # skip

>>> NumpyVersion('1.7')  # raises ValueError, add ".0"
    Traceback (most recent call last):
        ...
