cabal-debian-4.0.5: Create a debianization for a cabal package

Safe HaskellNone



Functions and instances used by but not related to cabal-debian. These could conceivably be moved into more general libraries.



curry3 :: ((a, b, c) -> d) -> a -> b -> c -> dSource

buildDebVersionMap :: IO DebMapSource

Read and parse the status file for installed debian packages: varlibdpkgstatus

strictReadF :: (Text -> r) -> FilePath -> IO rSource

replaceFile :: FilePath -> String -> IO ()Source

Write a file which we might still be reading from in order to compute the text argument.

modifyFile :: FilePath -> (String -> IO (Maybe String)) -> IO ()Source

Compute the new file contents from the old. If f returns Nothing do not write.

dpkgFileMap :: IO (Map FilePath (Set BinPkgName))Source

Create a map from pathname to the names of the packages that contains that pathname using the contents of the debian package info directory varlibdpkginfo.

debOfFile :: FilePath -> ReaderT (Map FilePath (Set BinPkgName)) IO (Maybe BinPkgName)Source

Given a path, return the name of the package that owns it.

cond :: t -> t -> Bool -> tSource

withCurrentDirectory :: FilePath -> IO a -> IO aSource

From Darcs.Utils - set the working directory and run an IO operation.

getDirectoryContents' :: FilePath -> IO [FilePath]Source

Get directory contents minus dot files.

setMapMaybe :: (Ord a, Ord b) => (a -> Maybe b) -> Set a -> Set bSource

zipMaps :: Ord k => (k -> Maybe a -> Maybe b -> Maybe c) -> Map k a -> Map k b -> Map k cSource

foldEmpty :: r -> ([a] -> r) -> [a] -> rSource

maybeL :: Lens a (Maybe b) -> Maybe b -> a -> aSource

If the current value of getL x is Nothing, replace it with f.

read' :: Read a => (String -> a) -> String -> aSource

modifyM :: MonadState a m => (a -> m a) -> m ()Source

intToVerbosity' :: Int -> VerbositySource

Version of intToVerbosity that first clamps its argument to the acceptable range (0-3).

(~=) :: Monad m => Lens a b -> b -> StateT a m ()Source

Set a lens value. (This is a version of Data.Lens.Lazy.~= that returns () instead of b.)

(~?=) :: Monad m => Lens a (Maybe b) -> Maybe b -> StateT a m ()Source

Set b if it currently isNothing and the argument isJust, that is 1. Nothing happens if the argument isNothing 2. Nothing happens if the current value isJust

(%=) :: Monad m => Lens a b -> (b -> b) -> StateT a m ()Source

Modify a value. (This is a version of Data.Lens.Lazy.%= that returns () instead of a.)

(+=) :: (Monad m, Ord b) => Lens a (Set b) -> b -> StateT a m ()Source

Insert an element into a (Set b)

(++=) :: (Monad m, Ord b) => Lens a (Map b c) -> (b, c) -> StateT a m ()Source

Insert an element into a (Map b c)

(+++=) :: (Monad m, Ord b, Monoid c) => Lens a (Map b c) -> (b, c) -> StateT a m ()Source

Insert an element into a (Map b (Set c))

listElemLens :: (a -> Bool) -> Lens [a] (Maybe a)Source

maybeLens :: a -> Lens a b -> Lens (Maybe a) bSource

fromEmpty :: Set a -> Set a -> Set aSource

fromSingleton :: a -> ([a] -> a) -> Set a -> aSource
