Distribution.Simple.LocalBuildInfo
Description
Once a package has been configured we have resolved conditionals and
dependencies, configured the compiler and other needed external programs.
The LocalBuildInfo is used to hold all this information. It holds the
install dirs, the compiler, the exact package dependencies, the configured
programs, the package database to use and a bunch of miscellaneous configure
flags. It gets saved and reloaded from a file (dist/setup-config). It gets
passed in to very many subsequent build actions.

externalPackageDeps :: LocalBuildInfo -> [(UnitId, MungedPackageId)] #
Deprecated: You almost certainly don't want this function, which agglomerates the dependencies of ALL enabled components. If you're using this to write out information on your dependencies, read off the dependencies directly from the actual component in question. To be removed in Cabal 3.0
External package dependencies for the package as a whole. This is the
union of the individual componentPackageDeps, less any internal deps.
localComponentId :: LocalBuildInfo -> ComponentId #
Extract the ComponentId from the public library component of a
LocalBuildInfo if it exists, or make a fake component ID based
on the package ID.
localUnitId :: LocalBuildInfo -> UnitId #
Extract the UnitId from the library component of a
LocalBuildInfo if it exists, or make a fake unit ID based on
the package ID.
localCompatPackageKey :: LocalBuildInfo -> String #
Extract the compatibility package key from the public library component of a
LocalBuildInfo if it exists, or make a fake package key based
on the package ID.

data ComponentName #
componentNameString :: ComponentName -> Maybe UnqualComponentName #
This gets the underlying unqualified component name. In fact, it is
guaranteed to uniquely identify a component, returning
Nothing if the ComponentName was for the public
library.
data ComponentLocalBuildInfo #
The first five fields are common across all algebraic variants.

foldComponent :: (Library -> a) -> (ForeignLib -> a) -> (Executable -> a) -> (TestSuite -> a) -> (Benchmark -> a) -> Component -> a #
componentName :: Component -> ComponentName #
componentBuildable :: Component -> Bool #
Is a component buildable (i.e., not marked with buildable: False)?
See also this note in
Distribution.Types.ComponentRequestedSpec.
Since: 2.0.0.2
pkgComponents :: PackageDescription -> [Component] #
All the components in the package.
pkgBuildableComponents :: PackageDescription -> [Component] #
A list of all components in the package that are buildable,
i.e., were not marked with buildable: False. This does NOT
indicate if we are actually going to build the component,
see enabledComponents instead.
Since: 2.0.0.2
getComponentLocalBuildInfo :: LocalBuildInfo -> ComponentName -> ComponentLocalBuildInfo #
Deprecated: This function is not well-defined, because a ComponentName does not uniquely identify a ComponentLocalBuildInfo. If you have a TargetInfo, you should use targetCLBI to get the ComponentLocalBuildInfo. Otherwise, use componentNameTargets to get all possible ComponentLocalBuildInfos. This will be removed in Cabal 2.2.
componentsInBuildOrder :: LocalBuildInfo -> [ComponentName] -> [ComponentLocalBuildInfo] #
Deprecated: You've got TargetInfo right? Use neededTargetsInBuildOrder on the UnitIds you can nodeKey out.
Arguments
| :: Bool | Building for inplace? |
| -> Bool | Generate prefix-relative library paths |
| -> LocalBuildInfo | |
| -> ComponentLocalBuildInfo | Component that is being built |
| -> NoCallStackIO [FilePath] |
Determine the directories containing the dynamic libraries of the transitive dependencies of the component we are building.
When wanted, and possible, returns paths relative to the installDirs prefix
allLibModules :: Library -> ComponentLocalBuildInfo -> [ModuleName] #
Get all module names that needed to be built by GHC; i.e., all
of these ModuleNames have interface files associated with them
that need to be installed.
withAllComponentsInBuildOrder :: PackageDescription -> LocalBuildInfo -> (Component -> ComponentLocalBuildInfo -> IO ()) -> IO () #
Perform the action on each buildable Library or Executable (Component)
in the PackageDescription, subject to the build order specified by the
compBuildOrder field of the given LocalBuildInfo
withComponentsInBuildOrder :: PackageDescription -> LocalBuildInfo -> [ComponentName] -> (Component -> ComponentLocalBuildInfo -> IO ()) -> IO () #
Deprecated: You have got a TargetInfo right? Use withNeededTargetsInBuildOrder on the UnitIds you can nodeKey out.
withComponentsLBI :: PackageDescription -> LocalBuildInfo -> (Component -> ComponentLocalBuildInfo -> IO ()) -> IO () #
Deprecated: Use withAllComponentsInBuildOrder
withLibLBI :: PackageDescription -> LocalBuildInfo -> (Library -> ComponentLocalBuildInfo -> IO ()) -> IO () #

description with the ComponentLocalBuildInfo.

Backwards compatibility function which computes the InstallDirs
assuming that $libname points to the public library (or some fake
package identifier if there is no public library.) IF AT ALL
