Distribution.ArchHs.Name

Naming conversion between haskell package in hackage and archlinux community repo.

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

1. for haskell libraries, their names must have haskell- prefix
2. for programs, it depends on circumstances
3. names should always be in lower case

However, it's not enough to prefix the string with haskell- and trasform 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, NAME_PRESET.json, manually. Once a package distributed to archlinux, whose name conform to above-mentioned situation, the name preset should be upgraded correspondingly.

NAME_PRESET.json will be loaded during the compilation, generating haskell code to be called in runtime.

Converting a archlinux community name to hackage name following these steps:

1. Find if the name preset contains this rule
2. If it contains, then use it; or remove the haskell- prefix

Converting a hackage name to archlinux community name following these steps:

1. Find if the name preset contains this rule
2. If it contains, then use it; or add the haskell- prefix

For details, see the type MyName and type class HasMyName with its instances.

Documentation

data MyName a

A general package name representation. It has a phantom a, which indexes this name. Normally, the index should be the data kinds of NameRep.

In Cabal API, packages' names are represented by the type PackageName; in arch-hs, names parsed from community.db are represented by the type ArchLinuxName. It would be tedious to use two converting functions everywhere, so here comes a intermediate data type to unify them, with type level constraints as bonus.
