Was this something which used to work for you, and then stopped?

I never saw this working

Wanted end result.

Hello

I have a special case where I try to update version in a .spec file. In this spec file the versioning scheme used is semver. However, the datasource (github-tags) is using a different versioning scheme (e.g. 1_0_0 instead of 1.0.0). I'm using regex manager and have a working configuration using the _ scheme, but I don't see a way how to "transform" the versioning scheme from the datasource to semver. Has anyone tried something like that before?

What you tried so far.

I updated the matchStrings and versioning (regex) to match both versioning schemes. This works but renovate tries to replace the dots in the semver with underscores which is not what I need.

You'd need regex versioning where you allow the separator to be . or _

Thanks for your answer. I already tried that using the following config:

    "regexManagers":[
        {
            "fileMatch":[
              "^openldap.spec"
            ],
            "matchStrings":[
              "Version:\\s+(?<currentValue>[\\d\\.]+)"
            ],
            "datasourceTemplate":"github-tags",
            "lookupNameTemplate":"openldap/openldap",
            "depNameTemplate":"openldap"
        }
    ],
    "packageRules":[
        {
            "matchPackageNames":[
              "openldap"
            ],
            "extractVersion":"^OPENLDAP_REL_ENG_(?<version>[\\d_]+)",
            "versioning": "regex:^(?<major>\\d)[_\\.](?<minor>\\d)[_\\.](?<patch>\\d)$"
          }
    ]

This results in the following warning:

DEBUG: manager.getUpdatedPackageFiles() reuseExistingBranch=false (repository=package-builds/openldap, branch=renovate/openldap-2.x)

       "foundValue": "2"
 WARN: Error updating branch: update failure (repository=package-builds/openldap, branch=renovate/openldap-2.x)

If I then update the matchStrings to include _ as well renovatebot creates a PR but replaces 2.6.x with 2_6_4?

Thanks I see the problem now. The regex versioning is working ok - it can compare 2.6.2 to 2_6_4 - but then it replaces the 2.6.2 with 2_6_4 instead of with 2.6.4.

I can't think of a way to get this to work without adding something similar to extractVersion called instead transformVersion which allows you to transform/massage a version

I see, that makes sense. Thanks for taking the time to look at this
