GHC.BaseDir
Description
Note [Base Dir] ~~~~~~~~~~~~~~~~~ GHC's base directory or top directory containers miscellaneous settings and the package database. The main compiler of course needs this directory to read those settings and read and write packages. ghc-pkg uses it to find the global package database too.
In the interest of making GHC builds more relocatable, many settings also will expand `${top_dir}` inside strings so GHC doesn't need to know it's on installation location at build time. ghc-pkg also can expand those variables and so needs the top dir location to do that too.
Synopsis
- expandTopDir :: FilePath -> String -> String
- expandPathVar :: String -> FilePath -> String -> String
- getBaseDir :: IO (Maybe String)
