# Documentation

Mostly the compiler deals in terms of `UnitId`s, which are md5 hashes of a package ID, keys of its dependencies, and Cabal flags. You're expected to pass in the unit id in the `-this-unit-id` flag. However, for wired-in packages like `base` & `rts`, we don't necessarily know what the version is, so these are handled specially; see .

# UnitId

packageConfigId :: PackageConfig -> UnitId Source #

Get the GHC `UnitId` right out of a Cabalish `PackageConfig`

# The PackageConfig type: information about a package

type PackageConfig = InstalledPackageInfo SourcePackageId PackageName UnitId ModuleName Source #

data InstalledPackageInfo srcpkgid srcpkgname unitid modulename :: * -> * -> * -> * -> * Source #

This is a subset of Cabal's `InstalledPackageInfo`, with just the bits that GHC is interested in.

data Version :: * Source #

A `Version` represents the version of a software entity.

An instance of `Eq` is provided, which implements exact equality modulo reordering of the tags in the `versionTags` field.

An instance of `Ord` is also provided, which gives lexicographic ordering on the `versionBranch` fields (i.e. 2.1 > 2.0, 1.2.3 > 1.2.2, etc.). This is expected to be sufficient for many uses, but note that you may need to use a more specific ordering for your versioning scheme. For example, some versioning schemes may include pre-releases which have tags `"pre1"`, `"pre2"`, and so on, and these would need to be taken into account when determining ordering. In some cases, date ordering may be more appropriate, so the application would have to look for `date` tags in the `versionTags` field and compare those. The bottom line is, don't always assume that `compare` and other `Ord` operations are the right thing for every `Version`.

Similarly, concrete representations of versions may differ. One possible concrete representation is provided (see `showVersion` and `parseVersion`), but depending on the application a different concrete representation may be more appropriate.

Constructors

Version |
Fields versionBranch :: [Int] The numeric branch for this version. This reflects the fact that most software versions are tree-structured; there is a main trunk which is tagged with versions at various points (1,2,3...), and the first branch off the trunk after version 3 is 3.1, the second branch off the trunk after version 3 is 3.2, and so on. The tree can be branched arbitrarily, just by adding more digits. We represent the branch as a list of `Int`, so version 3.2.1 becomes [3,2,1]. Lexicographic ordering (i.e. the default instance of `Ord` for `[Int]`) gives the natural ordering of branches. versionTags :: [String] A version can be tagged with an arbitrary list of strings. The interpretation of the list of tags is entirely dependent on the entity that this version applies to.
