Description

Explanation: Misc. Utilities, especially file-related utilities. Stuff used by multiple modules that doesn't fit elsewhere.

Documentation

die :: String -> IO a

rawSystemPath :: Int -> String -> [String] -> IO ExitCode

rawSystemVerbose :: Int -> String -> [String] -> IO ExitCode

rawSystemExit :: Int -> FilePath -> [String] -> IO ()

maybeExit :: IO ExitCode -> IO ()

rawSystemPathExit :: Int -> String -> [String] -> IO ()

smartCopySources

:: Int verbose -> FilePath build prefix (location of objects) -> FilePath Target directory -> [String] Modules -> [String] search suffixes -> IO () Copy the source files into the right directory. Looks in the build prefix for files that look like the input modules, based on the input search suffixes. It copies the files into the target directory.

copyFileVerbose :: Int -> FilePath -> FilePath -> IO ()

moduleToFilePath

:: [FilePath] search locations -> String Module Name -> [String] possible suffixes -> IO [FilePath] Get the file path for this particular module. In the IO monad because it looks for the actual file. Might eventually interface with preprocessor libraries in order to correctly locate more filenames. Returns Nothing if the file doesn't exist.

mkLibName

:: FilePath file Prefix -> String library name. -> String

currentDir :: FilePath

The path name that represents the current directory. May be system-specific. In Unix, it's ".".

dotToSep :: String -> String

withTempFile :: FilePath -> String -> (FilePath -> IO a) -> IO a

getOptionsFromSource :: FilePath -> IO ([Extension], [(CompilerFlavor, [String])], [String])

Read the initial part of a source file, before any Haskell code, and return the contents of any LANGUAGE, OPTIONS and INCLUDE pragmas.

stripComments

:: Bool preserve pragmas? -> String input source text -> String Strip comments from Haskell source.

defaultPackageDesc :: IO FilePath

Package description file (pkgname.cabal)

findPackageDesc

:: FilePath Where to look -> IO FilePath Find a package description file in the given directory. Looks for .cabal files.

defaultHookedPackageDesc :: IO (Maybe FilePath)

Optional auxiliary package information file (pkgname.buildinfo)

findHookedPackageDesc

:: FilePath Directory to search -> IO (Maybe FilePath) dir/pkgname.buildinfo, if present Find auxiliary package information in the given directory. Looks for .buildinfo files.
