Documentation

hie_bios_output :: String Source #

Environment variable containing the filepath to which cradle actions write their results to. If the filepath does not exist, cradle actions must create them.

hie_bios_ghc :: String Source #

Environment variable pointing to the GHC location used by cabal's and stack's GHC wrapper.

If not set, will default to sensible defaults.

hie_bios_ghc_args :: String Source #

Environment variable with extra arguments passed to the GHC location in cabal's and stack's GHC wrapper.

If not set, assume no extra arguments.

hie_bios_arg :: String Source #

Environment variable pointing to the source file location that caused the cradle action to be executed.

hie_bios_deps :: String Source #

Environment variable pointing to a filepath to which dependencies of a cradle can be written to by the cradle action.

data Cradle a Source #

The environment of a single Cradle. A Cradle is a unit for the respective build-system.

It contains the root directory of the Cradle, the name of the Cradle (for debugging purposes), and knows how to set up a GHC session that is able to compile files that are part of this Cradle.

A Cradle may be a single unit in the "cabal-install" context, or the whole package, comparable to how "stack" works.

Constructors

Cradle
Fields cradleRootDir :: FilePath The project root directory. cradleOptsProg :: CradleAction a The action which needs to be executed to get the correct command line arguments. cradleLogger :: LogAction IO (WithSeverity Log)

Fields actionName :: ActionName a Name of the action. runCradle :: FilePath -> [FilePath] -> IO (CradleLoadResult ComponentOptions) Options to compile the given file with. runGhcCmd :: [String] -> IO (CradleLoadResult String) Executes the `ghc` binary that is usually used to build the cradle. E.g. for a cabal cradle this should be equivalent to `cabal exec ghc -- args`

data CradleLoadResult r Source #

Result of an attempt to set up a GHC session for a Cradle. This is the go-to error handling mechanism. When possible, this should be preferred over throwing exceptions.

Constructors

CradleSuccess r	The cradle succeeded and returned these options.
CradleFail CradleError	We tried to load the cradle and it failed.
CradleNone	No attempt was made to load the cradle.

Option information for GHC

Constructors

ComponentOptions

Fields

componentOptions :: [String]
Command line options.
componentRoot :: FilePath
Root directory of the component. All componentOptions are either absolute, or relative to this directory.
componentDependencies :: [FilePath]
Dependencies of a cradle that might change the cradle. Contains both files specified in hie.yaml as well as specified by the build-tool if there is any. FilePaths are expected to be relative to the cradleRootDir to which this CradleAction belongs to. Files returned by this action might not actually exist. This is useful, because, sometimes, adding specific files changes the options that a Cradle may return, thus, needs reload as soon as these files are created.
