Documentation
withCurrentDirectory :: FilePath -> IO a -> IO a Source
Run action with current directory set
directoryContents :: FilePath -> IO [FilePath] Source
Get directory contents safely
traverseDirectory :: FilePath -> IO [FilePath] Source
Collect all file names in directory recursively
searchPath :: (MonadIO m, MonadPlus m) => FilePath -> (FilePath -> m a) -> m a Source
Search something up
haskellSource :: FilePath -> Bool Source
Is haskell source?
String utils
Helper
(.::) :: FromJSON a => HashMap Text Value -> Text -> Parser a Source
Workaround, sometimes we get HM.lookup "foo" v == Nothing, but lookup "foo" (HM.toList v) == Just smth
objectUnion :: Value -> Value -> Value Source
Union two JSON objects
Exceptions
liftException :: MonadCatch m => m a -> ErrorT String m a Source
Lift IO exception to ErrorT
liftExceptionM :: (MonadCatch m, Error e, MonadError e m) => m a -> m a Source
Lift IO exception to MonadError
liftIOErrors :: MonadCatch m => ErrorT String m a -> ErrorT String m a Source
Lift IO exceptions to ErrorT
