Support templating of sourceDirectory field

Tell us more.

We have multiple monorepos from which we build various private Python packages. These repos contain projects like so:

Monorepo
├── package-a
├── package-b
└── package-c

Each of these projects contain a README.md.

We would like to receive changelog links and expands on PRs opened by Renovate. Currently the only option is to create a packageRule for each project in the monorepo like so:

    ...
    {
      "customChangelogUrl": "https://github.com/CoolCompany/mono-repo",
      "sourceDirectory": "package-a",
      "matchDepNames": ["package-a"]
    },
    {
      "customChangelogUrl": "https://github.com/CoolCompany/mono-repo",
      "sourceDirectory": "package-b",
      "matchDepNames": ["package-b"]
    },
    ...

It would be really handy if we could template sourceDirectory and only need 1 package rule like so:

    {
      "customChangelogUrl": "https://github.com/CoolCompany/mono-repo",
      "sourceDirectory": "{{depName}}",
      "matchDepNames": ["package-a", "package-b", ...]
    },

I've read through the documentation and tested it and it seems that sourceDirectory does not support templating.

Is this a feature that you could add or would consider a contribution for?

sourceDirectory is not currently a supported config option in the first place.

[emil-vdw]

I understand. Thanks for taking the time.

Is there anything further I can do from my side?

[rarkins]

@zharinov did you reach a conclusion about whether it's safe to allow users to configure sourceUrl and sourceDirectory in packageRules? i.e. our caching is based on package + sourceurl + sourcedirectory and not package alone

[zharinov]

Yes, I remember it got different cache keys for different sourceUrl. Haven't checked for directories, though.
