type Module = GenModule Unit Source #

A Module is a pair of a Unit and a ModuleName.

type InstalledModule = GenModule UnitId Source #

A InstalledModule is a Module whose unit is identified with an UnitId.

type InstantiatedModule = GenModule InstantiatedUnit Source #

An InstantiatedModule is a Module whose unit is identified with an InstantiatedUnit.

mkModule :: u -> ModuleName -> GenModule u Source #

pprModule :: Module -> SDoc Source #

pprInstantiatedModule :: InstantiatedModule -> SDoc Source #

moduleFreeHoles :: GenModule (GenUnit u) -> UniqDSet ModuleName Source #

Calculate the free holes of a Module. If this set is non-empty, this module was defined in an indefinite library that had required signatures.

If a module has free holes, that means that substitutions can operate on it; if it has no free holes, substituting over a module has no effect.

Units

data GenUnit uid Source #

A unit identifier identifies a (possibly partially) instantiated library. It is primarily used as part of Module, which in turn is used in Name, which is used to give names to entities when typechecking.

There are two possible forms for a Unit:

1) It can be a RealUnit, in which case we just have a DefUnitId that uniquely identifies some fully compiled, installed library we have on disk.

2) It can be an VirtUnit. When we are typechecking a library with missing holes, we may need to instantiate a library on the fly (in which case we don't have any on-disk representation.) In that case, you have an InstantiatedUnit, which explicitly records the instantiation, so that we can substitute over it.

Constructors

RealUnit !(Definite uid)	Installed definite unit (either a fully instantiated unit or a closed unit)
VirtUnit !(GenInstantiatedUnit uid)	Virtual unit instantiated on-the-fly. It may be definite if all the holes are instantiated but we don't have code objects for it.
HoleUnit	Fake hole unit

type Unit = GenUnit UnitId Source #

newtype UnitId Source #

A UnitId identifies a built library in a database and is used to generate unique symbols, etc. It's usually of the form:

pkgname-1.2:libname+hash

These UnitId are provided to us via the -this-unit-id flag.

The library in question may be definite or indefinite; if it is indefinite, none of the holes have been filled (we never install partially instantiated libraries as we can cheaply instantiate them on-the-fly, cf VirtUnit). Put another way, an installed unit id is either fully instantiated, or not instantiated at all.

Constructors

UnitId
Fields unitIdFS :: FastString The full hashed unit identifier, including the component id and the hash.

data GenInstantiatedUnit unit Source #

An instantiated unit.

It identifies an indefinite library (with holes) that has been instantiated.

This unit may be indefinite or not (i.e. with remaining holes or not). If it is definite, we don't know if it has already been compiled and installed in a database. Nevertheless, we have a mechanism called "improvement" to try to match a fully instantiated unit with existing compiled and installed units: see Note [VirtUnit to RealUnit improvement].

An indefinite unit identifier pretty-prints to something like p[H=H,A=aimpl:A>] (p is the IndefUnitId, and the brackets enclose the module substitution).

Constructors

InstantiatedUnit

Fields

instUnitFS :: !FastString
A private, uniquely identifying representation of an InstantiatedUnit. This string is completely private to GHC and is just used to get a unique.
instUnitKey :: !Unique
Cached unique of unitFS.
instUnitInstanceOf :: !(Indefinite unit)
The indefinite unit being instantiated.
instUnitInsts :: !(GenInstantiations unit)
The sorted (by ModuleName) instantiations of this unit.
instUnitHoles :: UniqDSet ModuleName
A cache of the free module holes of instUnitInsts. This lets us efficiently tell if a InstantiatedUnit has been fully instantiated (empty set of free module holes) and whether or not a substitution can have any effect.

Boot modules

data IsBootInterface Source #

Indicates whether a module name is referring to a boot interface (hs-boot file) or regular module (hs file). We need to treat boot modules specially when building compilation graphs, since they break cycles. Regular source files and signature files are treated equivalently.
