Get the version (PEP 440).
|
||||
|
||||
A biased approach to the PEP 440 semantic version.
|
||||
|
||||
Provides a tuple structure which is sorted for comparisons `v1 > v2` etc.
|
||||
(major, minor, micro, release type, pre-release build, post-release build, development release build)
|
||||
Release types are named in is such a way they are comparable with ease.
|
||||
Accessors to check if a development, pre-release, or post-release build. Also provides accessor to get
|
||||
development status for setup files.
|
||||
|
||||
How it works (currently):
|
||||
|
||||
- You must specify a release type as either `final`, `alpha`, `beta`, or `candidate`.
|
||||
- To define a development release, you can use either `.dev`, `.dev-alpha`, `.dev-beta`, or `.dev-candidate`.
|
||||
The dot is used to ensure all development specifiers are sorted before `alpha`.
|
||||
You can specify a `dev` number for development builds, but do not have to as implicit development releases
|
||||
are allowed.
|
||||
- You must specify a `pre` value greater than zero if using a prerelease as this project (not PEP 440) does not
|
||||
allow implicit prereleases.
|
||||
- You can optionally set `post` to a value greater than zero to make the build a post release. While post releases
|
||||
are technically allowed in prereleases, it is strongly discouraged, so we are rejecting them. It should be
|
||||
noted that we do not allow `post0` even though PEP 440 does not restrict this. This project specifically
|
||||
does not allow implicit post releases.
|
||||
- It should be noted that we do not support epochs `1!` or local versions `+some-custom.version-1`.
|
||||
|
||||
Acceptable version releases:
|
||||
|
||||
```
|
||||
Version(1, 0, 0, "final") 1.0
|
||||
Version(1, 2, 0, "final") 1.2
