Extend poetry version xxx commands to support -beta.# and -rc.#

• I have searched the documentation and believe that my question is not covered.

Feature Request

poetry version prepatch (or prerelease, etc.) is great for incrementing the version from 1.2.3 to 1.2.4-alpha.0, and then to 1.2.4-alpha.1, etc. but this is the extent of the functionality.
https://python-poetry.org/docs/cli/#version

It would be great if we could add a few other commands to allow for pre-release name patterns. Adding alpha, beta, and rc would make sense as the other available commands to support other pre-release versions. This could work as:

$ poetry version alpha
Bumping version from 1.2.3 to 1.2.4-alpha.0
$ poetry version alpha
Bumping version from 1.2.4-alpha.0 to 1.2.4-alpha.1
$ poetry version beta
Bumping version from 1.2.4-alpha.1 to 1.2.4-beta.0
$ poetry version rc
Bumping version from 1.2.4-beta.0 to 1.2.4-rc.0
$ poetry version rc
Bumping version from 1.2.4-rc.0 to 1.2.4-rc.1
$ poetry version patch
Bumping version from 1.2.4-rc.1 to 1.2.4

This would adhere to the pre-release precedence order described here:
https://semver.org/#spec-item-11

Thanks for considering!

Perhaps adding an options flag --modifier=xxx here:

poetry/poetry/console/commands/version.py

Lines 14 to 21 in affe32d

	arguments = [
	argument(
	"version",
	"The version number or the rule to update the version.",
	optional=True,
	)
	]

Where modifier matches these:

poetry/poetry/semver/version.py

Line 300 in affe32d

m = re.match(r"(?i)^(a|alpha|b|beta|c|pre|rc|dev)[-.]?(\d+)?$", pre)

will it ever be made?
I need to bump versions between branches with bash commands because "poetry version" command doesn't support it.

A problem is that the library semantic_version crashes on the current poetry pre* version strings as it is strictly following the semver specification.

import semantic_version

semantic_version.Version("0.19.0a1")

Results in

ValueError                                Traceback (most recent call last)

    102     raise ValueError("Call either Version('1.2.3') or Version(major=1, ...).")
    104 if has_text:

    106 else:

    108     prerelease = tuple(prerelease or ())

    317 if not match:

    320 major, minor, patch, prerelease, build = match.groups()
    322 if _has_leading_zero(major):

This is still an issue... would like to be able to iterate on prepatch versions of a patch without overwriting previous alpha versions. Bumping the patch version isn't what we want because the patch hasn't been released yet.

To those who are still waiting this feature: Can you please have a look whether #8089 satisfies your use cases? It's different from the original proposal in this issue, but seems to offer similar functionality from my perspective. (Since I'm not using poetry version to bump versions myself, I don't have strong feelings.)

It's works for my usecase requiring an RC version.
Is there an estimate on when this will be released?
