Can't determine PV from upstream's version.
|
|
Do our best with some well-known versioning schemes:
|
|
|
|
* 1.0a1 (1.0_alpha1)
|
|
* 1.0-a1 (1.0_alpha1)
|
|
* 1.0b1 (1.0_beta1)
|
|
* 1.0-b1 (1.0_beta1)
|
|
* 1.0-r1234 (1.0_pre1234)
|
|
* 1.0dev-r1234 (1.0_pre1234)
|
|
* 1.0.dev-r1234 (1.0_pre1234)
|
|
* 1.0dev-20091118 (1.0_pre20091118)
|
|
|
|
Regex match.groups():
|
|
* pkgfoo-1.0.dev-r1234
|
|
* group 1 pv major (1.0)
|
|
* group 2 replace this with portage suffix (.dev-r)
|
|
* group 3 suffix version (1234)
|
|
|
|
The order of the regexes is significant. For instance if you have
|
|
.dev-r123, dev-r123 and -r123 you should order your regex's in
|
|
that order.
|
|
|
|
The chronological portage release versions are:
|
|
|
|
* _alpha
|
|
* _beta
|
|
* _pre
|
|
* _rc
|
|
* release
|
|
* _p
|
|
|
|
**Example:**
|
|
|
|
>>> gentoo_mangle_version('1.0b2')
|
|
'1.0_beta2'
|
|
|
|
.. note::
|
|
The number of regex's could have been reduced, but we use four
|
|
number of match.groups every time to simplify the code
