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)] 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.

type Key ComponentLocalBuildInfo # 

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 ComponentLocalBuildInfos. This will be removed in Cabal 2.2.

componentsInBuildOrder :: LocalBuildInfo -> [ComponentName] -> [ComponentLocalBuildInfo] Source #

Deprecated: You've got TargetInfo right? Use neededTargetsInBuildOrder on the UnitIds you can nodeKey out.

depLibraryPaths Source #

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] Source #

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 () 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 UnitIds 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.

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.
