Class Version

        Version
A class for obtaining and manipulating version numbers as well as creating the necessary version files Zenoss utilizes. 
>>> v1 = Version('Zenoss', 0, 22)
>>> v2 = Version('Zenoss', 0, 23, 4)
>>> v3 = Version('Zenoss', 0, 23, 7)
>>> v4 = Version('Zenoss', 1)
>>> v5 = Version('Zenoss', 1, 0, 2)
>>> v6 = Version('Zenoss', 1, 0, 2)
>>> v7 = Version('Zenoss', 1, 0, 2, 15729)
>>> v8 = Version('Zenoss', 1, 0, 2, 15730)
>>> v9 = Version('Zenoss', 1, 0, 3, 15729)

# test the display methods >>> v9.short() '1.0.3' >>> v9.long() 'Zenoss 1.0.3' >>> v9.full() 'Zenoss 1.0.3 r15729' >>> v2.tuple() (0, 23, 4)

# comparisons >>> v1 > v2 False >>> v3 > v2 True >>> v4 < v3 False >>> v4 > v5 False >>> v6 > v5 False >>> v6 >= v5 True >>> v6 == v5 True

# comparison, one with a revision number >>> v7 > v6 False

# revision number comparisons >>> v7 > v8 False >>> v8 > v9 False

# comparing non-Version objects with Version objects >>> '1.0.4' > v5 True >>> (1,0,1) > v5 False >>> 1 == v4 True >>> v4 == 1.0 True >>> '1.0' == v4 True

# comment/additional info >>> v10 = v9 >>> v10.setComment('A super-secret squirrel release') >>> v10.full() 'Zenoss 1.0.3 r15729 (A super-secret squirrel release)'

Method Details [hide private]

__init__(self, name, major=0, minor=0, micro=0, revision=0, comment='')
(Constructor)

source code 
x.__init__(...) initializes x; see x.__class__.__doc__ for signature
Overrides: object.__init__
(inherited documentation)

__cmp__(self, other)
(Comparison operator)

source code 

Comparse one verion to another. If the other version supplied is not a Version instance, attempt coercion.

The assumption here is that any non-Version object being compared to a Version object represents a verion of the same product with the same name but a different version number.

__repr__(self)
(Representation operator)

source code 
repr(x)
Overrides: object.__repr__
(inherited documentation)

__str__(self)
(Informal representation operator)

source code 
str(x)
Overrides: object.__str__
(inherited documentation)

parse(self, versionString)
Class Method

source code  

Parse the version info from a string. This method is usable without
having instantiated Version, and returns an instantiation.

The expected form is the following:
    software_name W.X.Y rZ
where W, X, and Y represent the major, minor, and micro version numbers
and Z is the subversion revision number.

Only the software name is required.

The version number is expected to have at least a major version number.
Minor and micro version numbers are optional, but if they are provided,
they must be dot-delimited.

Here are some example usages:

>>> v = Version.parse('Zenoss')
>>> repr(v)
'Version(Zenoss, 0, 0, 0,)'
>>> print v
[Zenoss, version 0.0.0]

>>> v = Version.parse('Zenoss 1')
>>> repr(v)
'Version(Zenoss, 1, 0, 0,)'
>>> print v
[Zenoss, version 1.0.0]

>>> v = Version.parse('Zenoss 0.26.4')
>>> repr(v)
'Version(Zenoss, 0, 26, 4,)'
>>> print v
[Zenoss, version 0.26.4]


>>> v = Version.parse('Zenoss 0.32.1 r13667')
>>> repr(v)
'Version(Zenoss, 0, 32, 1, r13667)'
>>> print v
[Zenoss, version 0.32.1 r13667]
