Hackport is a utility application for Gentoo Linux to ease the tasks for the Haskell Project.

The main purpose for Hackport is to interact with Hackage and create Ebuilds from Cabal packages. It also does handy functions to compare hackage, the overlay and the portage tree.

1. Build hackport binary by hand (or install it from haskell overlay).
2. Setup hackport database into overlay you plan to merge new ebuilds:

$ mkdir ~/overlays
$ cd ~/overlays
$ git clone git://github.com/gentoo-haskell/gentoo-haskell.git
$ cd gentoo-haskell
$ mkdir .hackport
$ hackport update
$ ls -1 .hackport/
    00-index.tar
    00-index.tar.gz

3. Add your ~/overlays/gentoo-haskell to PORTDIR_OVERLAY in /etc/make.conf.

Done! Now you can hackport merge <package-name> to get an ebuild merged to your overlay!

'hackport update'

Update the local copy of hackage's package list. You should run this every once in a while to get a more recent copy.

'hackport list [FILTER]'

Print packages from hackage, with an optional substring matching.

'hackport merge <package>'

Create a Gentoo Linux Ebuild for hackage package named <package>. The category defaults to dev-haskell, but is overridden if an older version has been merged previously to another category. The category can also be overridden with the syntax category/package. Example:

$ hackport merge x11-wm/xmonad

Hackport will make an ebuild that uses the haskell-cabal eclass, and set the following properties:

PN (package name)

Package name converted into lower case

PV (package version)

Package version with tags dropped.

KEYWORDS

Defaults to ~amd64 ~x86

CABAL_FEATURES

Populates the following features (see haskell-cabal.eclass): lib, profile, haddock, hoogle, hscolour, test-suite

DEPEND

GHC dependency defaults to >=dev-lang/ghc-6.6.1. Cabal dependency is fetched from Cabal field 'Cabal-Version'. All other package dependencies are converted into gentoo syntax. Range dependencies are flattened and usually needs manual tweaking.

DESCRIPTION

From Synopsis if it is non-empty, otherwise Description.

HOMEPAGE

From Homepage

SRC_URI

From package url

LICENSE

From cabal license converted into gentoo licenses

SLOT

Defaults to "0"

'hackport diff [missing|additions|newer|common]'

Prints a list showing a diff between hackage and the overlay. For each package it shows the latest version in both hackage and the overlay.

Optional parameters:

'all', the default action

List all packages.

'missing'

List packages that exist in hackage but not in the overlay, or where the hackage version is more recent.

'additions'

List packages only in the overlay, or where the overlay has a more recent version.

'newer'

List packages where hackage has a more recent version.

'common'

List packages where hackage and the overlay has the same version.

'hackport status [toportage]'

Provides an overview comparing the overlay to the portage tree. It will tell you, for each package and version, if the package exist

• only in the portage tree
• only in the overlay
• both in the portage tree and the overlay

• both in the portage tree and the overlay,

  but the ebuilds are not identical

Optional parameters:

'--to-portage'

Only print packages that are likely to be interesting to move to the portage tree. It will print packages when they exist in both portage and the overlay, and:

• the ebuilds differ, or
• the overlay has a more recent version

'hackport make-ebuild <category> <path/to/package.cabal>'

Generates standalone .ebuild file from .cabal spec and stores result to the overlay into <category>/<package> Option is useful for not-on-hackage packages and for debug purposes.
