build new haddock instructions

build-new-haddock.md

1. Download and build the newest haddock. The build instructions are in README.md.

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

   cabal sandbox init cabal sandbox add-source haddock-library cabal sandbox add-source haddock-api cabal install --dependencies-only cabal build

Then install the new haddock as haddock.real

cp dist/build/haddock/haddock /some/bin/dir/haddock.real

2. Create a wrapper script named haddock:

   #!/bin/sh

   /some/bin/dir/haddock.real --hyperlinked-source "$@"

Don't forget to make it executable and put it in your path.

4. Download and build standalone-haddock:

   mkdir build-standalone-haddock git clone https://github.com/feuerbach/standalone-haddock.git cd standalone-haddock cabal build cp dist/build/standalone-haddock/standalone-haddock /some/bin/dir/

An example of how to use standalone-haddock:

mkdir temp
cd temp
cabal get heredoc-0.2.0.0
standalone-haddock -o doc heredoc-0.2.0.0

Then open doc/heredoc/index.html in your browser.
