Custom package name for Hex dependency

Discussed in #32834

Tell us more.

What would you like Renovate to be able to do?

In Mix in elixir you can setup a dependency with a different name than the default one fetched from hex.pm, see: https://hex.pm/docs/usage#options

For example:

{:gun, "~> 2.0.0", hex: :grpc_gun},

This will fetch the grpc_gun dependency from hex.pm located here: https://hex.pm/packages/grpc_gun but will treat it locally as gun

If you have any ideas on how this should be implemented, please tell us here.

I think the mix manager should have an additional regex to search for such hex: option and use it to set PackageDependency.sourceUrl accordingly, which then would be used in the hex versioning?

Is this a feature you are interested in implementing yourself?
Yes, just need some discussion and guidance first

Reproduction: renovate-reproductions/32834#1

@rarkins what do you think of the approach proposed?

I am also thinking if instead the extract.ts module should set packageName to the hex package name here (if hex: option is set)

[rarkins]

SourceUrl is incorrect. PackageName is correct

[bernardo-martinez]

but datasource fetches release based on packageName

[rarkins]

Yes, exactly. If you set both depName and packageName then packageName will be used for the datasource lookup

[bernardo-martinez]

what do you think of: https://github.com/renovatebot/renovate/pull/32984/files

[rarkins]

Does it work end to end? Can you share a public repo demonstrating it?

[bernardo-martinez]

dunno exactly the best way to demonstrate it, but using the reproduction repo I:

1. Ran locally renovatebot within main, it resulted in this PR: test 3 bernardo-martinez/renovate-reproduction-32834#4 and this debug log
2. Checked out this branch and ran again, which resulted in closing the PR and the debug log I shared in the comments

how do you see it?

[rarkins]

Please also find an example where it success upgrades an alias like this, eg. from 2.0.0 to 2.0.1

[bernardo-martinez]

ok i think this new PR summarises the thing nicely:
