Or we could have: RationalVersion(...version bits...) RationalVersion.from_string(s) # this is a @classmethod > I have pushed the prototype in a bitbucket project so everyone can > work it out (just join the project) > > http://bitbucket.org/tarek/distutilsversion/ Thanks for putting this up. If we provide a way to construct a RationalVersion with version bits, then we need to discuss what those "version bits" look like. Currently the internal tuple data structure (`self.info`) looks like this (from verlib.py's description of the 'f' marker used to help with sort ordering, http://bitbucket.org/tarek/distutilsversion/src/cc93f5e1df3f/verlib.py#cl-163): # A marker used in the second and third parts of the `info` tuple, for # versions that don't have those segments, to sort properly. A example # of versions in sort order ('highest' last): # 1.0b1 ((1,0), ('b',1), ('f',)) # 1.0.dev345 ((1,0), ('f',), ('dev', 345)) # 1.0 ((1,0), ('f',), ('f',)) # 1.0.post345 ((1,0), ('f',), ('post', 345)) # ^ ^ # 'f' < 'b' -------------/ | # | # 'dev' < 'f' < 'post' -----------/ # Other letters would do, bug 'f' for 'final' is kind of nice. Is this what we would want the constructor to take? RationalVersion( (1,0), ('b', 1) ) # 1.0b1 RationalVersion( (1,0), ('f',), ('post', 345) ) # 1.0.post345 It seems a little too low-level. We could allow something a little nicer: RationalVersion( (1, 0, 'b', 1) ) # 1.0b1 RationalVersion( (1, 0, 'post', 345) ) # 1.0.post345 If we did this, then we'd probably want these attributes on RationalVersion: >>> v = RationalVersion((1,0,'b',1)) >>> str(v) '1.0b1' >>> v.info (1, 0, 'b', 1) >>> v._cmp_info # use for comparison ((1, 0), ('b', 1), ('f',)) Thoughts?
