digitalmars.D.learn - Dub, Git, Mercurial, Bazaar

have I missed it's ability to work with DVCS repositories?

If Dub cannot handle DVCS repositories, it needs to be able to.

The rationale is that people can access dependencies that are available
but not yet, or never will be, in the central repository. The use case
that matters is working with a dependency that is not yet, but
definitely will be in the central repository.

Experience of Rust, and Herd with Ceylon, shows this to be very
valuable to community activity.

You can use local repository if you want

How go and cargo know where the local repository is to handle that?

I fear we may well have started talking at cross purposes. At the risk
of doing the wrong thing I'll reset this thread with:

Go allows for any Git, Mercurial or Bazaar repository as a dependency.
It fetches the source into the workspace and compiles into the
workspace. The go language uses URIs to specify the import so the DVCS
nature is up front =E2=80=93 and leads to lots of vendoring problems. There=
 is
only the Go distribution and DVCS repositories.

Cargo fetches source from the central crate repository or from a DVCS
repository depending on the contents of the Cargo.toml file. The crate
names are the only thing the application source code knows about. There
is a central repository and DVCS repositories.

Dub cannot get from a DVCS repository but has a sequence of
repositories it can reach. It is feasible that these local Dub
repositories could have been got by DVCS, but this is a manual thing
not something Dub handles, unlike Go and Cargo. I feel that Dub should
behave more like Cargo. =20

I see. Thanks for clarification.

FYI, if we wanted a user configurable interfacing to any source of 
projects we would need some complicated "scripting" to allow for it.

E.g. I have a little bit of code that can help with this[0].
I'm currently designing a UI for it but ugh, it would be a lot of work 
to get this working for dub.
