data LocalBuildInfo

Data cached after configuration step. Constructors LocalBuildInfo prefix :: FilePath The installation directory (eg. usrlocal, or C:Program Filesfoo-1.2 on Windows. compiler :: Compiler The compiler we're building with buildDir :: FilePath Where to put the result of building. packageDeps :: [PackageIdentifier] Which packages we depend on, exactly. The PackageDescription 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. withHaddock :: (Maybe FilePath) Might be the location of the Haddock executable. withHappy :: (Maybe FilePath) Might be the location of the Happy executable. withAlex :: (Maybe FilePath) Might be the location of the Alex executable. withHsc2hs :: (Maybe FilePath) Might be the location of the Hsc2hs executable. withCpphs :: (Maybe FilePath) Might be the location of the Cpphs executable.

findProgram

:: String program name -> Maybe FilePath optional explicit path -> IO (Maybe FilePath) Return the explicit path if given, otherwise look for the program name in the path.
