Summary

I see these two use cases, but there might be more:

1. Incrementing the number of a prerelease

This means going from 1.2.3a4 to 1.2.3a5, for example. I think this can be handled by adding a new allowed value to --bump. For example prerelease-counter: uv version --bump prerelease-counter.

2. Adding or removing a prerelease suffix

This means going from 1.2.3a5 to 1.2.3, for example. I think this can be handled by a new argument to uv version. For example --set-suffix: uv version --set-suffix none. Allowed values would be dev, alpha, beta, rc, none, post.

Example

$ uv version --short
0.4.1.dev0
$ uv version --bump prerelease-counter
0.4.1.dev0 => 0.4.1.dev1
$ uv version --set-suffix none
0.4.1.dev1 => 0.4.1
$ uv version --bump patch
0.4.1 => 0.4.2
$ uv version --set-suffix alpha
0.4.2 => 0.4.2a0
$ uv version --bump prerelease-counter
0.4.2a0 => 0.4.2a1
