First, one +needs to build haddocks of all components which can be done with: + +.. code-block:: none + + cabal haddock --haddock-html \ + --haddock-quickjump \ + --haddock-option="--use-index=../doc-index.html" \ + --haddock-option="--use-contents=../index.html" \ + --haddock-option="--base-url=.." \ + all + +The new ``--base-url`` option will allow to access the static files from the +main directory (in this example its the relative ``./..`` directory). It will +also prevent ``haddock`` from copying its static files to each of the +documentation folders, we're only need a single copy of them where the +``--base-url`` option points to. + +The second step requires to copy all the haddocks to a common directory, let's +say ``./docs``, this will depend on your project and it might look like: + +.. code-block:: none + + cp -r dist-newstyle/build/x86_64-linux/ghc-9.0.1/package-a-0.1.0.0/doc/html/package-a/ docs + cp -r dist-newstyle/build/x86_64-linux/ghc-9.0.1/package-b-0.1.0.0/doc/html/package-b/ docs + +Note that you can also include documentation of other packages in this way, +e.g. ``base``, but you need to know where it is hidden on your hard-drive. + +To build html and js (``quickjump``) indexes one can now invoke ``haddock`` with: + +.. code-block:: none + + haddock \ + -o docs \ + --quickjump --gen-index --gen-contents \ + --read-interface=package-a,docs/package-a/package-a.haddock \ + --read-interface=package-b,docs/package-b/package-b.haddock + +Note: the ``PATH`` in ``--read-interface=PATH,...`` must be a relative url of +a package it points to (relative to the ``docs`` directory). + +There's an example project which shows how to do that posted `here +<https://github.com/coot/haddock-example>`_, which haddocks are served on +`github-pages <https://coot.github.io/haddock-example>`_. |
