Instances
componentNameToComponent :: ComponentName -> Component Source #
type ComponentDep a = (Component, a) Source #
Dependency for a single component.
data ComponentDeps a Source #
Fine-grained dependencies for a package.
Typically used as ComponentDeps [Dependency], to represent the list of
dependencies for each named component within a package.
Instances
Constructing ComponentDeps
empty :: ComponentDeps a Source #
fromList :: Monoid a => [ComponentDep a] -> ComponentDeps a Source #
singleton :: Component -> a -> ComponentDeps a Source #
insert :: Monoid a => Component -> a -> ComponentDeps a -> ComponentDeps a Source #
zip :: (Monoid a, Monoid b) => ComponentDeps a -> ComponentDeps b -> ComponentDeps (a, b) Source #
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 Source #
Keep only selected components (and their associated deps info).
mapDeps :: (Component -> a -> b) -> ComponentDeps a -> ComponentDeps b Source #
Keep only selected components (and their associated deps info).
fromLibraryDeps :: a -> ComponentDeps a Source #
ComponentDeps containing library dependencies only
fromSetupDeps :: a -> ComponentDeps a Source #
ComponentDeps containing setup dependencies only.
fromInstalled :: a -> ComponentDeps a Source #
ComponentDeps for installed packages.
We assume that installed packages only record their library dependencies.
Deconstructing ComponentDeps
toList :: ComponentDeps a -> [ComponentDep a] Source #
flatDeps :: Monoid a => ComponentDeps a -> a Source #
nonSetupDeps :: Monoid a => ComponentDeps a -> a Source #
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 Source #
Library dependencies proper only. (Includes dependencies of internal libraries.)
setupDeps :: Monoid a => ComponentDeps a -> a Source #
Setup dependencies.
select :: Monoid a => (Component -> Bool) -> ComponentDeps a -> a Source #
Select dependencies satisfying a given predicate.
components :: ComponentDeps a -> Set Component Source #
List components
