arch-hs: Distribute hackage packages to archlinux

This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.

Warnings:

arch-hs is a command-line program, which simplifies the process of producing and maintaining haskell packages for archlinux distribution by automating the PKGBUILD generation with the dependency resolving and template filling. Currently, arch-hs is unstable, so packagers should not trust it 100%, but always follow the Haskell package guidelines.

arch-hs

GitHub CI Build Status Hackage MIT license

A program generating PKGBUILD for hackage packages. Special thanks to felixonmars.

Notice that arch-hs will always support only the latest GHC version.

Introduction

Given the name of a package in hackage, arch-hs can generate PKGBUILD files, not only for the package whose name is given, but also for all dependencies missing in community. arch-hs has a naive built-in dependency solver, which can fetch those dependencies and find out which are required to be packaged. During the dependency calculation, all version constraints will be discarded due to the arch haskell packaging strategy, thus there is no guarantee of dependencies' version consistency.

Prerequisite

arch-hs is just a PKGBUILD text file generator, which is not integrated with pacman, depending on nothing than:

Installation

Both arch-hs and arch-hs-diff are portable, which means that they are not restricted to Arch Linux. However, if you want to run them in other systems, you have to build them from source.

Install the latest release

# pacman -S arch-hs

arch-hs is available in community, so you can install it using pacman.

Install the development version

# pacman -S arch-hs-git

The -git version is available in archlinuxcn, following the latest git commit.

Build

$ git clone https://github.com/berberman/arch-hs

Then build it via stack or cabal.

Stack

$ stack build

Cabal (dynamic)

$ cabal configure --disable-library-vanilla --enable-shared --enable-executable-dynamic --ghc-options=-dynamic 
$ cabal build

Usage

Just run arch-hs in command line with options and a target. Here is an example: we will create the archlinux package of accelerate:

$ arch-hs -o ~/test accelerate

......

  ⓘ Recommended package order (from topological sort):
1. unique
2. tasty-kat
3. accelerate

......

  ⓘ Write file: /home/berberman/test/haskell-accelerate/PKGBUILD
  ⓘ Write file: /home/berberman/test/haskell-unique/PKGBUILD
  ⓘ Write file: /home/berberman/test/haskell-tasty-kat/PKGBUILD
  ✔ Success!

This message tells us that in order to package accelerate, we must package unique and tasty-kat first sequentially, because accelerate dependents on them to build or test, whereas they are not present in archlinux community repo.

$ tree ~/test
/home/berberman/Desktop/test
├── haskell-accelerate
│   └── PKGBUILD
├── haskell-tasty-kat
│   └── PKGBUILD
└── haskell-unique
    └── PKGBUILD

arch-hs will generate PKGBUILD for each package. Let's see what we have in ./haskell-accelerate/PKGBUILD:

}

arch-hs will collect the information from hackage db, and apply it into a fixed template after some processing steps including renaming, matching license, and filling out dependencies etc. However, packaging haven't been done so far. arch-hs may does well statically, but we should guarantee that this package can be built by ghc with the latest dependencies; hence some patchs may be required in prepare(), such as uusi.

Options

Output

$ arch-hs -o ~/test TARGET

Using -o can generate a series of PKGBUILD including TARGET with its dependencies into the output dir. If you don't pass it, only dependency calculation will occur.

Flag Assignments

$ arch-hs -f TARGET:FLAG_A:true TARGET

Using -f can pass flags, which may affect the results of resolving.

AUR Searching

$ arch-hs -a TARGET

With -a, arch-hs will regard AUR as another package provider, and it will try to search missing packages in AUR as well.

Skipping Components

$ arch-hs -s COMPONENT_A TARGET

Using -s can force skip runnable components in dependency resolving. This is useful when a package doesn't provide flag to disable its runnables, which will be built by default but are trivial in system level packaging. Notice that this only makes sense in the lifetime of arch-hs, whereas generated PKGBUILD and actual build processes will not be affected.

Extra Cabal Files

$ arch-hs -e ~/TARGET/TARGET.cabal TARGET

For Testing Purposes Only

Using -e can include extra .cabal files as supplementary. Useful when the TARGET hasn't been released to hackage.

Trace

$ arch-hs --trace TARGET

With --trace, arch-hs can print the process of dependency resolving into stdout.

$ arch-hs --trace-file foo.log TARGET

Similar to --trace, but the log will be written into a file.

Uusi

$ arch-hs -o ~/test --uusi TARGET

With --uusi, arch-hs will generate following snippet for each package:

prepare() {
  uusi $_hkgname-$pkgver/$_hkgname.cabal
}

See uusi for details.

Name preset

To distribute a haskell package to archlinux, the name of package should be changed according to the naming convention:

However, it's not enough to prefix the string with haskell- and transform to lower case; in some special situations, the hackage name may have haskell- prefix already, or the case is irregular, thus we have to a name preset manually. Once a package distributed to archlinux, whose name conform to above-mentioned situation, the name preset should be upgraded correspondingly.

Diff

arch-hs also provides a component called arch-hs-diff. arch-hs-diff can show the differences of package description between two versions of a package. This is useful in the subsequent maintenance of a package. Example:

$ arch-hs-diff HTTP 4000.3.14 4000.3.15
  ▶ You didn't pass -f, different flag values may make difference in dependency resolving.

  ✔ Success!

arch-hs-diff does not require hackage db, it downloads cabal files from hackage server instead.
