This document aims to cover standards and guidelines for producing good Haskell packages on Arch.

Package naming

For Haskell libraries, use haskell-libraryname usually the same name as on hackage.

Note: The package name should be entirely lowercase.


See PKGBUILD#arch.

Every Haskell library or program is architecture-dependent.


The preferred source of a Haskell program or library is from hackage. PKGBUILD#source source=() array should use the following URL template:


Note that a custom _hkgname variable is used instead of pkgname since Haskell packages are generally prefixed with haskell-. This variable can generically be defined as follows:


Rebuild order

When a Haskell library changes its build flags or is updated all dependent packages need to be rebuild.

PKGBUILD library example

Packaging a Haskell library is different from packaging a Haskell program, the libraries packaged in Arch Linux are meant to be used by packaged Haskell programs.
