Reverse dependencies of a package?

package
#1

Are there existing tools for evaluating the reverse dependencies of a package? That is, for determining the packages that depend directly or indirectly on a particular package?

It occurred to me that, if not, this might be an occasion for me to learn a bit more about the Registries used with Pkg3. How would I begin exploring the TOML capabilities if I decided to try to parse a Registry?

Pkg.dependents will give you the direct dependencies at least. Shouldn’t be hard to call it recursively if needed.

Thanks. It seems that I should have done a bit more research before asking the question.:grimacing:

https://juliaobserver.com will also give you this information.
