Possible to set a max limit for branchname?

[trondhindenes]

We have a bunch of branch rules in our gitversion config, most are variations of label: 'feat-{BranchName}'. One issue we're seeing is that some branches are super-long and since we in some systems derive resource name from the generated version (kubernetes etc) this causes issues from time to time.

Is it possible to limit BranchName's length ala label: 'feat-{BranchName[0:50]}' or similar?

I would honestly not want to add this type of features into GitVersion, we should keep the tool only for computing the version from the git history, anything not related should be either set as input or computed as output by the user of the tool.

that's fair. Do you have any tricks on how we could manipulate the branch name as it is seen by GitVersion? I see it is possible to pass "label" as an input variable, but it's not possible to override "BranchName". Overriding label and passing it as input would require us to move some of the logic that is currently controlled by Gitversion out of it.

Instead we could of parse the semver after GitVersion has processed it, but as we'd want to retain the trailing number, we'd have to strip away the "middle section" and that seems clunky as well.

I'd be grateful for any tips on how to best accomplish a max-length.

I've created #4503 to discuss a possible solution to this.

Why not just changing the regular expression to e.g. ^features?[\/-](?<BranchName>.{8})? I have implemented this feature of named grouping to have the flexibility.
