| die :: String -> IO a |
|
| dieWithLocation :: FilePath -> Maybe Int -> String -> IO a |
|
| warn :: String -> IO () |

| rawSystemPath :: Int -> String -> [String] -> IO ExitCode |
|
| rawSystemVerbose :: Int -> FilePath -> [String] -> IO ExitCode |

| rawSystemExit :: Int -> FilePath -> [String] -> IO () |
|
| maybeExit :: IO ExitCode -> IO () |
|
| xargs :: Int -> (FilePath -> [String] -> IO ExitCode) -> FilePath -> [String] -> [String] -> IO ExitCode |
Like the unix xargs program. Useful for when we've got very long command
lines that might overflow an OS limit on command line length and so you
need to invoke a command multiple times to get all the args in.
Use it with either of the rawSystem variants above. For example:
xargs (32*1024) (rawSystemPath verbose) prog fixedArgs bigArgs

| matchesDescFile :: FilePath -> Bool |

| rawSystemPathExit :: Int -> String -> [String] -> IO () |
|
| smartCopySources |
| :: Int | verbose
| | -> [FilePath] | build prefix (location of objects)
| | -> FilePath | Target directory
| | -> [String] | Modules
| | -> [String] | search suffixes
| | -> Bool | Exit if no such modules
| | -> Bool | Preserve directory structure
| | -> 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 () |
|
| copyDirectoryRecursiveVerbose :: 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 empty list if no such files exist.

|
| currentDir :: FilePath |
| The path name that represents the current directory.
In Unix, it's ".", but this is system-specific.
(E.g. AmigaOS uses the empty string "" for the current directory.)

| dirOf :: FilePath -> FilePath |
|
| dotToSep :: String -> String |
|
| withTempFile :: FilePath -> String -> (FilePath -> IO a) -> IO a |
|
| findFile |
|
|
| 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.
