# Documentation

class (IsString s, Monoid s, Show s) => GlibString s where #

Minimal complete definition

withUTFString, withUTFStringLen, peekUTFString, maybePeekUTFString, peekUTFStringLen, newUTFString, newUTFStringLen, genUTFOfs, stringLength, unPrintf

Methods

withUTFString :: s -> (CString -> IO a) -> IO a #

Like `withCString` but using the UTF-8 encoding.

withUTFStringLen :: s -> (CStringLen -> IO a) -> IO a #

Like `withCStringLen` but using the UTF-8 encoding.

peekUTFString :: CString -> IO s #

Like `peekCString` but using the UTF-8 encoding.

maybePeekUTFString :: CString -> IO (Maybe s) #

Like `maybePeek` `peekCString` but using the UTF-8 encoding to retrieve UTF-8 from a `CString` which may be the `nullPtr`.

peekUTFStringLen :: CStringLen -> IO s #

Like `peekCStringLen` but using the UTF-8 encoding.

newUTFString :: s -> IO CString #

Like `newCString` but using the UTF-8 encoding.

newUTFStringLen :: s -> IO CStringLen #

Like Define newUTFStringLen to emit UTF-8.

genUTFOfs :: s -> UTFCorrection #

Create a list of offset corrections.

stringLength :: s -> Int #

Length of the string in characters

unPrintf :: s -> s #

readUTFString :: GlibString s => CString -> IO s #

Like like `peekUTFString` but then frees the string using g_free

readCString :: CString -> IO String #

Like `peekCString` but then frees the string using `g_free`.

withUTFStrings :: GlibString s => [s] -> ([CString] -> IO a) -> IO a #

Temporarily allocate a list of UTF-8 `CString`s.

withUTFStringArray :: GlibString s => [s] -> (Ptr CString -> IO a) -> IO a #

Temporarily allocate an array of UTF-8 encoded `CString`s.

withUTFStringArray0 :: GlibString s => [s] -> (Ptr CString -> IO a) -> IO a #

Temporarily allocate a null-terminated array of UTF-8 encoded `CString`s.

peekUTFStringArray :: GlibString s => Int -> Ptr CString -> IO [s] #

Convert an array (of the given length) of UTF-8 encoded `CString`s to a list of Haskell `String`s.

peekUTFStringArray0 :: GlibString s => Ptr CString -> IO [s] #

Convert a null-terminated array of UTF-8 encoded `CString`s to a list of Haskell `String`s.

readUTFStringArray0 :: GlibString s => Ptr CString -> IO [s] #

Like `peekUTFStringArray0` but then free the string array including all strings.

To be used when functions indicate that their return value should be freed with `g_strfreev`.

data UTFCorrection #

Offset correction for String to UTF8 mapping.
