initSession :: GhcMonad m => ComponentOptions -> m [Target] Source #
Start a GHC session and set some sensible options for tooling to use. Creates a folder in the cache directory to cache interface files to make reloading faster.
getRuntimeGhcLibDir :: Cradle a -> IO (CradleLoadResult FilePath) Source #
getRuntimeGhcLibDir cradle will give you the ghc libDir:
do not use runGhcCmd directly.
Obtains libdir by calling runCradleGhc on the provided cradle.
getRuntimeGhcVersion :: Cradle a -> IO (CradleLoadResult String) Source #
Gets the version of ghc used when compiling the cradle. It is based off of
getRuntimeGhcLibDir. If it can't work out the verison reliably, it will
return a CradleError
makeDynFlagsAbsolute :: FilePath -> DynFlags -> DynFlags Source #
Make filepaths in the given DynFlags absolute.
This makes the DynFlags independent of the current working directory.
getCacheDir :: FilePath -> IO FilePath Source #
Back in the day we used to clear the cache at the start of each session, however, it's not really necessary as 1. There is one cache dir for any change in options. 2. Interface files are resistent to bad option changes anyway.
clearInterfaceCache :: FilePath -> IO () clearInterfaceCache fp = do cd <- getCacheDir fp res <- doesPathExist cd when res (removeDirectoryRecursive cd)
Prepends the cache directory used by the library to the supplied file path. It tries to use the path under the environment variable `$HIE_BIOS_CACHE_DIR` and falls back to the standard `$XDG_CACHE_HOME/hie-bios` if the former is not set
