Distribution.Simple.LocalBuildInfo

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.

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 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 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.

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.

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

-> Bool

Generate prefix-relative library paths

-> LocalBuildInfo 
-> ComponentLocalBuildInfo

Component that is being built

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.

type InstallDirTemplates = InstallDirs PathTemplate Source #

The installation directories in terms of PathTemplates that contain variables.

The defaults for most of the directories are relative to each other, in particular they are all relative to a single prefix. This makes it convenient for the user to override the default installation directory by only having to specify --prefix=... rather than overriding each individually. This is done by allowing $-style variables in the dirs. These are expanded by textual substitution (see substPathTemplate).

A few of these installation directories are split into two components, the dir and subdir. The full installation path is formed by combining the two together with /. The reason for this is compatibility with other Unix build systems which also support --libdir and --datadir. We would like users to be able to configure --libdir=/usr/lib64 for example but because by default we want to support installing multiple versions of packages and building the same package for multiple compilers we append the libsubdir to get: /usr/lib64/$libname/$compiler.

An additional complication is the need to support relocatable packages on systems which support such things, like Windows.

data InstallDirs dir Source #

The directories where we will install files for packages.

We have several different directories for different types of files since many systems have conventions whereby different types of files in a package are installed in different directories. This is particularly the case on Unix style systems.

substituteInstallDirTemplates :: PathTemplateEnv -> InstallDirTemplates -> InstallDirTemplates Source #

Substitute the install dir templates into each other.

To prevent cyclic substitutions, only some variables are allowed in particular dir templates. If out of scope vars are present, they are not substituted for. Checking for any remaining unsubstituted vars can be done as a subsequent operation.

The reason it is done this way is so that in prefixRelativeInstallDirs we can replace prefix with the PrefixVar and get resulting PathTemplates that still have the PrefixVar in them. Doing this makes it each to check which paths are relative to the $prefix.

toPathTemplate :: FilePath -> PathTemplate Source #

Convert a FilePath to a PathTemplate including any template vars.

fromPathTemplate :: PathTemplate -> FilePath Source #

Convert back to a path, any remaining vars are included

initialPathTemplateEnv :: PackageIdentifier -> UnitId -> CompilerInfo -> Platform -> PathTemplateEnv Source #

The initial environment has all the static stuff but no paths

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.
