# Install not only the Hoogle library and executable, but also a local Hoogle
|
|
# database which provides "Source" links to all specified 'packages' -- or the
|
|
# current Haskell Platform if no custom package set is provided.
|
|
#
|
|
# It is intended to be used in config.nix similarly to:
|
|
#
|
|
# { packageOverrides = pkgs: rec {
|
|
#
|
|
# haskellPackages =
|
|
# let callPackage = pkgs.lib.callPackageWith haskellPackages;
|
|
# in pkgs.recurseIntoAttrs (pkgs.haskellPackages.override {
|
|
# extension = self: super: {
|
|
# hoogleLocal = pkgs.haskellPackages.hoogleLocal.override {
|
|
# packages = with pkgs.haskellPackages; [
|
|
# mmorph
|
|
# monadControl
|
|
# ];
|
|
# };
|
|
# };
|
|
# });
|
|
# }}
|
|
#
|
|
# This will build mmorph and monadControl, and have the hoogle installation
|
|
# refer to their documentation via symlink so they are not garbage collected.
