Clear message

Describe DistutilsVersionFight here.

Larry Hastings

Sorry for the crazy moon proposal here, but I have example code that I think even works. (Though I'm not operating on enough sleep, so sorry 'cause I already know the code is crappy.)

The basic idea:

I doubt y'all will go for this. But I thought you should at least consider supporting a more flexible format. People like to express their version numbers a wide variety of ways, and most folks could find a way to map their personal weird approach to something this approach would make consistent.

Erik LaBianca

Just throwing this out there since it's a little different from what was discussed earlier, but I think has some merit:

* Versions are a series of integers. Ie 0.0.1, 1.0.0, or Versions define the "intended API level" of the software in question.

Pre-release versions are denoted by a version, followed by a string (I suggest "pre" but it doesn't really matter), followed by a series of integers, seperated by periods if needed. Pre-releases are important because while they may be an implementation of a future API version, they are likely to be buggy or incomplete.

* For instance 1.0.0pre2.1 > 1.0.0pre2 > 1.0.0pre1 < 1.0.0.

* Or for the case of daily builds, 1.0.0pre1 > 1.0.0pre0.20090327 < 1.0.0

This obviously trades away the flexibility of roll-your-own naming entirely, but makes up for it by defining a standard that leaves enough flexibility to represent most cases easily. It is easy to parse and explain, extensible, and able to cover most use cases aside from that of "backported bug fixes". I believe that eliminating words will be a net positive because it eliminates any complaints along the lines of "you included alpha, beta, and rc but where's pre-release or testing?!".

I hope to have some code up soon, as well.

Georg Brandl

Simple modification of Larry's proposal: split the tuple at the "tag" (defined by an alpha part in the version number), and allow only one tag. Map alpha, beta and rc to known negative values, and every other tag to a value lower than all of these (so that setuptools' .dev-r102 would still work correctly).
