registerAllowOverwrite :: Bool
Allows re-registering / overwriting an existing package
registerMultiInstance :: Bool
Insist on the ability to register multiple instances of a single version of a single package. This will fail if the hc-pkg does not support it, see nativeMultiInstance and recacheMultiInstance.
registerSuppressFilesCheck :: Bool
Require that no checks are performed on the existence of package files mentioned in the registration info. This must be used if registering prior to putting the files in their final place. This will fail if the hc-pkg does not support it, see suppressFilesCheck.

defaultRegisterOptions :: RegisterOptions #

Defaults are True, False and False

Actions

init :: HcPkgInfo -> Verbosity -> Bool -> FilePath -> IO () #

Call hc-pkg to initialise a package database at the location {path}.

hc-pkg init {path}

invoke :: HcPkgInfo -> Verbosity -> PackageDBStack -> [String] -> IO () #

Run hc-pkg using a given package DB stack, directly forwarding the provided command-line arguments to it.

register :: HcPkgInfo -> Verbosity -> PackageDBStack -> InstalledPackageInfo -> RegisterOptions -> IO () #

Call hc-pkg to register a package.

hc-pkg register {filename | -} [--user | --global | --package-db]

unregister :: HcPkgInfo -> Verbosity -> PackageDB -> PackageId -> IO () #

Call hc-pkg to unregister a package

hc-pkg unregister [pkgid] [--user | --global | --package-db]

recache :: HcPkgInfo -> Verbosity -> PackageDB -> IO () #

Call hc-pkg to recache the registered packages.

hc-pkg recache [--user | --global | --package-db]

expose :: HcPkgInfo -> Verbosity -> PackageDB -> PackageId -> IO () #

Call hc-pkg to expose a package.

hc-pkg expose [pkgid] [--user | --global | --package-db]

hide :: HcPkgInfo -> Verbosity -> PackageDB -> PackageId -> IO () #

Call hc-pkg to hide a package.

hc-pkg hide [pkgid] [--user | --global | --package-db]

dump :: HcPkgInfo -> Verbosity -> PackageDB -> IO [InstalledPackageInfo] #

Call hc-pkg to get all the details of all the packages in the given package database.

describe :: HcPkgInfo -> Verbosity -> PackageDBStack -> PackageId -> IO [InstalledPackageInfo] #

Call hc-pkg to retrieve a specific package

hc-pkg describe [pkgid] [--user | --global | --package-db]

list :: HcPkgInfo -> Verbosity -> PackageDB -> IO [PackageId] #

Call hc-pkg to get the source package Id of all the packages in the given package database.

This is much less information than with dump, but also rather quicker. Note in particular that it does not include the UnitId, just the source PackageId which is not necessarily unique in any package db.
