v prefix semver?

[NLZ]

Is it semver-compatible if the version tag has a v prefix, like v1.2.3?
Or do I have to use wud.tag.transform: ^v(\d+\.\d+\.\d+)$$ => $$1?

The node package for semver confirms that it indeed handles the v prefix.
https://www.npmjs.com/package/semver#versions
Also the parse code seems to be quite forgiving:

wud/app/tag/index.js

Line 12 in 7e579d2

function parse(rawVersion) {

Here are some tests with it:

v8.13.9 -> 8.13.9
5.26.2.10099-ls280 -> 5.26.2
1.42.1.10060-4e8b05daf-ls278 -> 1.42.1
1.0.1277_17-08-2025 -> 1.0.1277
version-6.13.1 -> 6.13.1
nightly-version-2.13.2.4685 -> 2.13.2
3.1.0.1073-1-ls221 -> 3.1.0
4e00d3ba-ls21 -> 4.0.0
nightly-0.4.19.2811-ls400 -> 0.4.19

So if the version has more than 3 tags then everything gets cut off.

But it's might not be the best idea to leave it to it's devices, as the loose semver cleaning does some weird bug with this version:

4.0.15.2941-ls290 -> 4.0.1-5.2941-ls290 

So yeah, it's better to transform with wud if it's not a 3 part semver, like for 4.0.15.2941-ls290 using wud.tag.transform: ^(\d+\.\d+\.\d+)\.(\d+)-ls(\d+)$$ => $$1-$$2.$$3

I used the trick with capturing groups to transform a tag from X.Y.Z.P to X.Y.Z-P. I can confirm the ${transformed} value is as expected. However, if I try to access the P value with ${prerelease}, I get undefined (for usage in wud.link.template). I wonder if the version levels are parsed to link template vars only from the original tag, and not the transformed value?
