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.

data LocalBuildInfo Source #
Data cached after configuration step. See also
ConfigFlags
.
LocalBuildInfo | |
|
externalPackageDeps :: LocalBuildInfo -> [(UnitId, MungedPackageId)] Source #
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 2.2
External package dependencies for the package as a whole. This is the
union of the individual componentPackageDeps
, less any internal deps.
localComponentId :: LocalBuildInfo -> ComponentId Source #
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 Source #
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 Source #
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.
Buildable package components
data ComponentName Source #
componentNameString :: ComponentName -> Maybe UnqualComponentName Source #
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 Source #
The first five fields are common across all algebraic variants.

foldComponent :: (Library -> a) -> (ForeignLib -> a) -> (Executable -> a) -> (TestSuite -> a) -> (Benchmark -> a) -> Component -> a Source #
componentBuildable :: Component -> Bool Source #
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] Source #
All the components in the package.
pkgBuildableComponents :: PackageDescription -> [Component] Source #
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 Source #
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 ComponentLocalBuildInfo
s. This will be removed in Cabal 2.2.
componentsInBuildOrder :: LocalBuildInfo -> [ComponentName] -> [ComponentLocalBuildInfo] Source #
Deprecated: You've got TargetInfo
right? Use neededTargetsInBuildOrder
on the UnitId
s you can nodeKey
out.
:: 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] Source #
Get all module names that needed to be built by GHC; i.e., all
of these ModuleName
s have interface files associated with them
that need to be installed.
withAllComponentsInBuildOrder :: PackageDescription -> LocalBuildInfo -> (Component -> ComponentLocalBuildInfo -> IO ()) -> IO () Source #
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 () Source #
Deprecated: You have got a TargetInfo
right? Use withNeededTargetsInBuildOrder
on the UnitId
s you can nodeKey
out.
withComponentsLBI :: PackageDescription -> LocalBuildInfo -> (Component -> ComponentLocalBuildInfo -> IO ()) -> IO () Source #
Deprecated: Use withAllComponentsInBuildOrder
withLibLBI :: PackageDescription -> LocalBuildInfo -> (Library -> ComponentLocalBuildInfo -> IO ()) -> IO () Source #
Perform the action on each enabled library
in the package
description with the ComponentLocalBuildInfo
.
withExeLBI :: PackageDescription -> LocalBuildInfo -> (Executable -> ComponentLocalBuildInfo -> IO ()) -> IO () Source #
Perform the action on each enabled Executable
in the package
description. Extended version of withExe
that also gives corresponding
build info.
withBenchLBI :: PackageDescription -> LocalBuildInfo -> (Benchmark -> ComponentLocalBuildInfo -> IO ()) -> IO () Source #
Perform the action on each enabled Benchmark
in the package
description.
withTestLBI :: PackageDescription -> LocalBuildInfo -> (TestSuite -> ComponentLocalBuildInfo -> IO ()) -> IO () Source #
enabledTestLBIs :: PackageDescription -> LocalBuildInfo -> [(TestSuite, ComponentLocalBuildInfo)] Source #
enabledBenchLBIs :: PackageDescription -> LocalBuildInfo -> [(Benchmark, ComponentLocalBuildInfo)] Source #
Installation directories
absoluteInstallDirs :: PackageDescription -> LocalBuildInfo -> CopyDest -> InstallDirs FilePath Source #
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
POSSIBLE, please use absoluteComponentInstallDirs
instead.
prefixRelativeInstallDirs :: PackageId -> LocalBuildInfo -> InstallDirs (Maybe FilePath) Source #
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
POSSIBLE, please use prefixRelativeComponentInstallDirs
instead.
absoluteComponentInstallDirs :: PackageDescription -> LocalBuildInfo -> UnitId -> CopyDest -> InstallDirs FilePath Source #
See absoluteInstallDirs
.
prefixRelativeComponentInstallDirs :: PackageId -> LocalBuildInfo -> UnitId -> InstallDirs (Maybe FilePath) Source #
