Hacking

To get started you'll need a latest GHC release installed.

Clone the repository:

  git clone https://github.com/haskell/haddock.git
  cd haddock

and then proceed using your favourite build tool.

Using cabal new-build

cabal new-build -w ghc-8.2.1
# build & run the test suite
cabal new-test -w ghc-8.2.1

Using Cabal sandboxes

cabal sandbox init
cabal sandbox add-source haddock-library
cabal sandbox add-source haddock-api
cabal sandbox add-source haddock-test
# adjust -j to the number of cores you want to use
cabal install -j4 --dependencies-only --enable-tests
cabal configure --enable-tests
cabal build -j4
# run the test suite
export HADDOCK_PATH="dist/build/haddock/haddock"
cabal test

Using Stack

stack init
stack install
# run the test suite
export HADDOCK_PATH="$HOME/.local/bin/haddock"
stack test

Git Branches

If you're a GHC developer and want to update Haddock to work with your changes, you should be working on ghc-head branch instead of master. See instructions at https://ghc.haskell.org/trac/ghc/wiki/WorkingConventions/Git/Submodules for an example workflow.

The master branch usually requires a GHC from the latest GHC stable branch. The required GHC version can be inferred from the version bounds on ghc in the respective .cabal files.
