First, no need to use that fork — all patches have been merged into Cabal master at https://github.com/haskell/Cabal. (However, they are not released yet, so you still have to build the git version.)

OK, I've built cabal from github in a clean test account.

Second, no, installation won't happen automatically. At the moment you have to do that manually, like this:

cabal install --haskell-suite -w hs-gen-iface mtl

I may be missing something obvious, but which package provides haskell-suite? I see that it's a group of repositories on github.

haskell-suite is not a real package or program. In this context, it's the name of a "virtual compiler" known to cabal.

$ cabal install --haskell-suite -w parsec cabal: The program haskell-suite is required but it could not be found.

The correct command is $ cabal install --haskell-suite -w hs-gen-iface parsec The -w flag lets cabal know that you want to compile using hs-gen-iface, which is a concrete compiler implementing the haskell-suite interface.

It'd be nice to add a cabal.config option to do that automatically.

Ditto for --haddock-hyperlink-source which I use all the time so that I get locally built documentation. Very handy for when I work at a cafe.

Yeah, ideally haddock and hscolor should be just separate compilers, just like ghc and hs-gen-iface are. The user would then specify in cabal.config what set of compilers to use for simple `cabal install $pkg`.

I want to make the development process in Vim as smooth as possible. A newbie should be able to ask "what's this?" or "where is this from?" and get a quick answer, right there in the editor. Hoogle is very useful but there should be an editor-integrated solution that works locally and gives an answer like "this symbol in this file comes from this module on this system".
