l.a.v.version : module documentation

Returns True if version is a valid debian version string

As per http://www.debian.org/doc/debian-policy/ch-controlfields.html (Except we appear to need to allow ~ characters, which is not documented in the spec.)

>>> valid_debian_version('1')
True
>>> valid_debian_version('1.0')
True
>>> valid_debian_version('1:1.0')
True
>>> valid_debian_version('1.0-1')
True
>>> valid_debian_version("1:1.0-1")
True
>>> valid_debian_version("3.4-2.1")
True
>>> valid_debian_version("1.5.4-1.woody.0")
True
>>> valid_debian_version("1.5.4-1.WOODY.0")
True
>>> valid_debian_version("1.6-0+1.5a-4")
True
>>> valid_debian_version("1.3~rc1-4")
True
>>> valid_debian_version("1:")
False
>>> valid_debian_version("1:-")
False
>>> valid_debian_version("44-")
False
>>> valid_debian_version("~-~")
False
>>> valid_debian_version("0~")
True
>>> valid_debian_version("0~-~")
True
>>> valid_debian_version(":44")
False
>>> valid_debian_version("foo:")
False
>>> valid_debian_version("12:12:alpha-alpha")
True
>>> valid_debian_version("build9-6")
True

A sane version number for use by ProductRelease and DistroSeries.

We may make it less strict if required, but it would be nice if we can enforce simple version strings because we use them in URLs

>>> sane_version('hello')
True
>>> sane_version('HELLO')
True
>>> sane_version('1.0')
True
>>> sane_version('12:45')
False
>>> sane_version('1b2')
True
>>> sane_version('1-')
False
>>> sane_version('1-2')
True
>>> sane_version('-2')
False
>>> sane_version('uncle sam')
False
>>> sane_version('uncle_sam')
True
>>> sane_version('uncle-sam')
True
