Allow use of more than one remote repo (hackage).

[schell]

It looks like at some point cabal would support building packages from more than one repo. Is this possible?

[23Skidoo]

This only requires changing how we parse the --remote-repo option. The globalRemoteRepos fields is already a list:

    globalRemoteRepos       :: [RemoteRepo],     -- ^ Available Hackage servers.

Looking at the code, the possibility of more than one repo is anticipated.

What is the expected use case? Private hackage servers?

[schell]

Yes, a private hackage server.

As far as I know (i.e. unless it was very recently broken) this just works. You just specify multiple entries in the .cabal/config file (or pass multiple --remote-repo flags on the command line).

e.g.

remote-repo: hackage.haskell.org:http://hackage.haskell.org/
remote-repo: private-collection:http://hackage.local/

Make sure to list the private one second so that it overrides, and so that uploads go there.

Thanks @dcoutts! It works. I think before I was passing the --remote-repo arg incorrectly.
