proposal: cmd/go: support darcs vcs

[ghost]

Copied from Wikipedia: Darcs is a distributed version control system created by David Roundy. Key features include the ability to choose which changes to accept from other repositories, interaction with either other local (on-disk) repositories or remote repositories via SSH, HTTP, or email, and an unusually interactive interface. The developers also emphasize the use of advanced software tools for verifying correctness: the expressive type system of the functional programming language Haskell enforces some properties, and randomized testing via QuickCheck verifies many others. The name is a recursive acronym for Darcs Advanced Revision Control System.

Are there any source code hosting sites that support Darcs?

[ghost]

@ianlancetaylor currently I only know of https://hub.darcs.net/

[andrewarchi]

A VCS with a similar model to Darcs is Pijul, with hosting at https://nest.pijul.com/.

[FrankDMartinez]

I would greatly appreciate Darcs support as well.

[LukeMauldin]

Is there any way to support Golang modules in either Darcs or Pijul without the core Go team adding support? Didn’t know if there were work-around for non-native VCSes? I would think perforce falls into this category too.

it's possible: the go command understands a "mod" vcs where it will request directly from a proxy. As long as the proxy can get the code and zip it up correctly (and respond to the metadata requests) then it will work

[LukeMauldin]

Yes, that makes sense. Thank you for reminding me of that functionality
