same on Debian, file:///usr/share/doc/ghc-doc/html/libraries/index.html is one of the most-visited locations in my computer :-)
For Debian, you can check where we deviate from the Haskell Platform on http://people.debian.org/~nomeata/platform.html and http://people.debian.org/~nomeata/hackagevsdebian.html gives you an idea of our coverage of Hackage.
And, something that we are proud of: The dependencies between the Haskell library packages include the ABI hash, so an apt-get upgrade will never break installed Haskell libraries, but only upgrade if all depending packages have been rebuilt.
Are these binary or source packages that you use the ABI hash?
The binary packages. Here is an example for how we make sure that an ABI incompatible change to web-routes requires a rebuild of yesod, and that until that happens the user will not get the new web-routes package installed. $ apt-cache show libghc-yesod-dev|grep Depends Depends: libghc-base-dev-4.3.1.0-91c38, libghc-base64-bytestring-dev-0.1.0.2-2bc90, libghc-blaze-builder-dev-0.2.1.4-eb4c4, libghc-bytestring-dev-0.9.1.10-6aa1e, libghc-cereal-dev-0.3.3.0-7fd4a, libghc-clientsession-dev-0.4.1-493f6, libghc-containers-dev-0.4.0.0-b4885, libghc-data-default-dev-0.2.0.1-9411c, libghc-directory-dev-1.1.0.0-393d8, libghc-email-validate-dev-0.2.6-c13c2, libghc-failure-dev-0.1.0.1-1e2c3, libghc-hamlet-dev-0.6.1.2-ec8f2, libghc-neither-dev-0.1.0-0adb6, libghc-network-dev-2.3.0.2-824dd, libghc-old-locale-dev-1.0.0.2-161f7, libghc-parsec-dev-3.1.1-33474, libghc-persistent-dev-0.3.1.3-d494b, libghc-puremd5-dev-2.1.0.3-754be, libghc-random-dev-1.0.0.3-7511f, libghc-template-haskell-dev-2.5.0.0-95716, libghc-text-dev-0.11.0.6-139d7, libghc-time-dev-1.2.0.3-34932, libghc-transformers-dev-0.2.2.0-4bbbf, libghc-wai-dev-0.2.2.1-53001, libghc-wai-extra-dev-0.2.4.2-4646d, libghc-web-routes-dev-0.23.4-ab46a, libghc-web-routes-quasi-dev-0.6.3.1-5c04c, libghc-xss-sanitize-dev-0.2.6-b2c10, libc6 (>= 2.7), libffi5 (>= 3.0.4), libgmp10, zlib1g (>= 1:1.1.4) $ apt-cache show libghc-web-routes-dev|grep Provides Provides: libghc-web-routes-dev-0.23.4-ab46a
Also, how do you manage to update the documentation index on package installation/removal?
The ghc-doc package installs a dpkg trigger that watches certain directories (the directories where library install their package descriptions and .haddock files). If such a change happens, /usr/lib/ghc-doc/gen_contents_index is run, which can be seen here: http://anonscm.debian.org/darcs/pkg-haskell/ghc/gen_contents_index.in Greetings, Joachim -- Joachim "nomeata" Breitner Debian Developer nomeata@debian.org | ICQ# 74513189 | GPG-Keyid: 4743206C JID: nomeata@joachim-breitner.de | http://people.debian.org/~nomeata
