stackage
"Stable Hackage," tools for creating a vetted set of packages from Hackage.
A note about the codebase: the goal is to minimize dependencies and have the maximum range of supported compiler versions. Therefore, we avoid anything "complicated." For example, instead of using the text package, we use Strings everywhere.
Get your package included
In order to get your package included in the set of stable packages, you should
send a pull request against this repository. In the Stackage.Config module,
there's a function called defaultStablePackages. In general, to add a set of
packages, you would add:
mapM_ (add "your-email-address") $ words
"package1 package2 package3"
You can follow the examples of the other sets of packages in that function. Once you've done this, you should confirm that your newly added packages are compatible with the rest of stackage by building the package set.
You should also read the maintainers agreement.
Build the package set
As this project is just starting, we don't really have a solid set of steps. In general, the following set of commands should be good for getting started:
cabal update
git clone https://github.com/fpco/stackage
cd stackage
cabal sandbox init # requires cabal-install 1.18
cabal install --only-dependencies
cabal configure
cabal build
./dist/build/stackage/stackage select
./dist/build/stackage/stackage check
./dist/build/stackage/stackage build # takes a *long* time
./dist/build/stackage/stackage test # also takes a *long* time
Notes
Make sure to have Cabal-1.16 installed in either your global or user database, regardless of any sandboxing, as custom build types require it to be present. You must build with cabal-install 1.16, due to several important bug fixes.
Using a non-Haskell Platform versions of GHC
By default, Stackage bases itself off of the Haskell Platform for determining
which packages are core packages, and locks down package versions to match the
Haskell Platform selections. This works fine when you are compiling with the
same version of GHC as the Haskell Platform was built on. If you're using a
different version of GHC, you'll probably need to use the following options for
the select call:
--no-platform --use-global-db
The former says to disregard Haskell Platform package versions, and the latter says to determine which packages are core packages based on their presence in the global package database.
