Contents

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.

Synopsis

Documentation

data LocalBuildInfo

Data cached after configuration step. See also ConfigFlags.

Constructors

LocalBuildInfo

Options passed to the configuration step. Needed to re-run configuration when .cabal is out of date

flagAssignment :: FlagAssignment

The final set of flags which were picked for this package

extraConfigArgs :: [String]

Extra args on the command line for the configuration step. Needed to re-run configuration when .cabal is out of date

compiler :: Compiler

The compiler we're building with

hostPlatform :: Platform

The platform we're building for

buildDir :: FilePath

Where to build the package.

componentsConfigs :: [(ComponentName, ComponentLocalBuildInfo, [ComponentName])]

All the components to build, ordered by topological sort, and with their dependencies over the intrapackage dependency graph

installedPkgs :: InstalledPackageIndex

All the info about the installed packages that the current package depends on (directly or indirectly).

pkgDescrFile :: Maybe FilePath

the filename containing the .cabal file, if available

localPkgDescr :: PackageDescription

The resolved package description, that does not contain any conditionals.

withPrograms :: ProgramConfiguration

Location and args for all programs

withPackageDB :: PackageDBStack

Whether to build normal libs.

withProfLib :: Bool

Whether to build profiling versions of libs.

withSharedLib :: Bool

Whether to build shared versions of libs.

withDynExe :: Bool

Whether to link executables dynamically

withProfExe :: Bool

Whether to build executables for profiling.

withProfLibDetail :: ProfDetailLevel

Level of automatic profile detail.

withProfExeDetail :: ProfDetailLevel

Level of automatic profile detail.

withOptimization :: OptimisationLevel

Whether to build with optimization (if available).

progSuffix :: PathTemplate

Suffix to be appended to installed executables

relocatable :: Bool
 

Instances

externalPackageDeps :: LocalBuildInfo -> [(UnitId, PackageId)]

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 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 ComponentId from the library component of a LocalBuildInfo if it exists, or make a fake compatibility package key based on the package ID.

Instances

data ComponentLocalBuildInfo

Constructors

LibComponentLocalBuildInfo 

Fields

componentPackageDeps :: [(UnitId, PackageId)]

Resolved internal and external package dependencies for this component. The BuildInfo specifies a set of build dependencies that must be satisfied in terms of version ranges. This field fixes those dependencies to the specific versions available on this machine for this compiler.

componentUnitId :: UnitId
 
componentCompatPackageKey :: String
 
componentExposedModules :: [ExposedModule]
 
componentPackageRenaming :: Map PackageName ModuleRenaming
 
ExeComponentLocalBuildInfo 

Fields

componentPackageDeps :: [(UnitId, PackageId)]

Resolved internal and external package dependencies for this component. The BuildInfo specifies a set of build dependencies that must be satisfied in terms of version ranges. This field fixes those dependencies to the specific versions available on this machine for this compiler.

componentPackageRenaming :: Map PackageName ModuleRenaming
 
TestComponentLocalBuildInfo 

Fields

componentPackageDeps :: [(UnitId, PackageId)]

Resolved internal and external package dependencies for this component. The BuildInfo specifies a set of build dependencies that must be satisfied in terms of version ranges. This field fixes those dependencies to the specific versions available on this machine for this compiler.

componentPackageRenaming :: Map PackageName ModuleRenaming
 
BenchComponentLocalBuildInfo 

Fields

componentPackageDeps :: [(UnitId, PackageId)]

Resolved internal and external package dependencies for this component. The BuildInfo specifies a set of build dependencies that must be satisfied in terms of version ranges. This field fixes those dependencies to the specific versions available on this machine for this compiler.

componentPackageRenaming :: Map PackageName ModuleRenaming
 

foldComponent :: (Library -> a) -> (Executable -> a) -> (TestSuite -> a) -> (Benchmark -> a) -> Component -> a

pkgComponents :: PackageDescription -> [Component]

All the components in the package (libs, exes, or test suites).

pkgEnabledComponents :: PackageDescription -> [Component]

All the components in the package that are buildable and enabled. Thus this excludes non-buildable components and test suites or benchmarks that have been disabled.

checkComponentsCyclic :: Ord key => [(node, key, [key])] -> Maybe [(node, key, [key])]

depLibraryPaths

Arguments

:: Bool

Building for inplace?

-> Bool

Generate prefix-relative library paths

-> LocalBuildInfo 
-> ComponentLocalBuildInfo

Component that is being built

-> IO [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

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

withComponentsLBI :: PackageDescription -> LocalBuildInfo -> (Component -> ComponentLocalBuildInfo -> IO ()) -> IO ()

Deprecated: Use withAllComponentsInBuildOrder

withLibLBI :: PackageDescription -> LocalBuildInfo -> (Library -> ComponentLocalBuildInfo -> IO ()) -> IO ()

If the package description has a library section, call the given function with the library build info as argument. Extended version of withLib that also gives corresponding build info.

withExeLBI :: PackageDescription -> LocalBuildInfo -> (Executable -> ComponentLocalBuildInfo -> IO ()) -> IO ()

Perform the action on each buildable Executable in the package description. Extended version of withExe that also gives corresponding build info.
