System.Glib.UTFString

Description

This module adds CString-like functions that handle UTF8 strings.

Synopsis

Documentation

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

Methods

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

Like withCString but using the UTF-8 encoding.

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

Like withCStringLen but using the UTF-8 encoding.

peekUTFString :: CString -> IO s Source

Like peekCString but using the UTF-8 encoding.

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

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 Source

Like peekCStringLen but using the UTF-8 encoding.

newUTFString :: s -> IO CString Source

Like newCString but using the UTF-8 encoding.

newUTFStringLen :: s -> IO CStringLen Source

Like Define newUTFStringLen to emit UTF-8.

genUTFOfs :: s -> UTFCorrection Source

Create a list of offset corrections.

stringLength :: s -> Int Source

Length of the string in characters

unPrintf :: s -> s Source

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

Like like peekUTFString but then frees the string using g_free

readCString :: CString -> IO String Source

Like peekCString but then frees the string using g_free.

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

Temporarily allocate a list of UTF-8 CStrings.

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

Temporarily allocate an array of UTF-8 encoded CStrings.

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

Temporarily allocate a null-terminated array of UTF-8 encoded CStrings.

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

Convert an array (of the given length) of UTF-8 encoded CStrings to a list of Haskell Strings.

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

Convert a null-terminated array of UTF-8 encoded CStrings to a list of Haskell Strings.

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

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 Source

Offset correction for String to UTF8 mapping.

Instances

class (fp ~ FilePath) => GlibFilePath fp where Source

Methods

withUTFFilePath :: fp -> (CString -> IO a) -> IO a Source

peekUTFFilePath :: CString -> IO fp Source

withUTFFilePaths :: GlibFilePath fp => [fp] -> ([CString] -> IO a) -> IO a Source

withUTFFilePathArray :: GlibFilePath fp => [fp] -> (Ptr CString -> IO a) -> IO a Source
