Construct a FPath from some type
Minimal complete definition
emptyFPath :: FPath Source #
Empty FPath
Construction, deconstruction, predicates
fpathFromStr :: FilePath -> FPath Source #
Construct FPath from FilePath
mkFPathFromDirsFile :: Show s => [s] -> s -> FPath Source #
fpathToStr :: FPath -> FilePath Source #
Conversion to FilePath
fpathIsEmpty :: FPath -> Bool Source #
Is FPath empty?
fpathRemoveSuff :: FPath -> FPath Source #
Remove suffix
fpathRemoveDir :: FPath -> FPath Source #
Remove dir
fpathIsAbsolute :: FPath -> Bool Source #
fpathUnAppendDir :: FPath -> FilePath -> FPath Source #
Remove common trailing part of dir. Note: does not check whether it really is a suffix.
