This will work if everyone stores the url in scm.url. But your migration guide already recommends otherwise for replacing the scm attribute

https://docs.conan.io/1/migrating_to_2.0/recipes.html#the-scm-attribute

So you'd have to include sources.url as well. And any other possible structure because it is never validated. I think we'd have to create an interface for interacting with conandata to be able to do this reliably.

This has been normalized in Conan 2 with the coordinates_to_conandata and checkout_from_conandata_coordinates helpers, that will always store it in conandata->scm->url. The intention is to fully normalize it, and even leverage this information for other functionality.

https://docs.conan.io/1/migrating_to_2.0/recipes.html#the-scm-attribute

This is a mistake in the docs, and should be updated to reflect the new convention.

[jasal82]

I see, that's good to know. That means I'll have to create another release of our base conanfile that uses the conventions from those new functions, so that we can replace them with the actual function calls once we're ready to switch to Conan 2.

Yes, sorry about that, the "standardization" of the conandata->scm->url/commit happened in #15377, that was 1 year after the Conan 2.0 launch, so the Conan 1 docs were no longer updated with these things.
