Description

Fine-grained package dependencies

Like many others, this module is meant to be "double-imported":

    import Distribution.Solver.Types.ComponentDeps (
        Component
      , ComponentDep
      , ComponentDeps
      )
    import qualified Distribution.Solver.Types.ComponentDeps as CD

componentNameToComponent :: ComponentName -> Component #

type ComponentDep a = (Component, a) #

Dependency for a single component.

data ComponentDeps a #

Fine-grained dependencies for a package.

Typically used as `ComponentDeps [Dependency]`, to represent the list of dependencies for each named component within a package.

## Constructing ComponentDeps

empty :: ComponentDeps a #

fromList :: Monoid a => [ComponentDep a] -> ComponentDeps a #

singleton :: Component -> a -> ComponentDeps a #

insert :: Monoid a => Component -> a -> ComponentDeps a -> ComponentDeps a #

zip :: (Monoid a, Monoid b) => ComponentDeps a -> ComponentDeps b -> ComponentDeps (a, b) #

Zip two `ComponentDeps` together by `Component`, using `mempty` as the neutral element when a `Component` is present only in one.

filterDeps :: (Component -> a -> Bool) -> ComponentDeps a -> ComponentDeps a #

Keep only selected components (and their associated deps info).

mapDeps :: (Component -> a -> b) -> ComponentDeps a -> ComponentDeps b #

Keep only selected components (and their associated deps info).

fromLibraryDeps :: a -> ComponentDeps a #

ComponentDeps containing library dependencies only

fromSetupDeps :: a -> ComponentDeps a #

ComponentDeps containing setup dependencies only.

fromInstalled :: a -> ComponentDeps a #

ComponentDeps for installed packages.

We assume that installed packages only record their library dependencies.

## Deconstructing ComponentDeps

toList :: ComponentDeps a -> [ComponentDep a] #

flatDeps :: Monoid a => ComponentDeps a -> a #

All dependencies of a package.

This is just a synonym for `fold`, but perhaps a use of `flatDeps` is more obvious than a use of `fold`, and moreover this avoids introducing lots of `#ifdef`s for 7.10 just for the use of `fold`.

nonSetupDeps :: Monoid a => ComponentDeps a -> a #

All dependencies except the setup dependencies.

Prior to the introduction of setup dependencies in version 1.24 this would have been _all_ dependencies.

libraryDeps :: Monoid a => ComponentDeps a -> a #

Library dependencies proper only. (Includes dependencies of internal libraries.)

setupDeps :: Monoid a => ComponentDeps a -> a #

Setup dependencies.

select :: Monoid a => (Component -> Bool) -> ComponentDeps a -> a #

Select dependencies satisfying a given predicate.

components :: ComponentDeps a -> Set Component #

List components
