String construction

toPlatformStringUtf :: MonadThrow m => String -> m WindowsString Source #

Convert a String.

On windows this encodes as UTF16, which is a pretty good guess. On unix this encodes as UTF8, which is a good guess.

Throws a EncodingException if encoding fails.

toPlatformStringEnc :: TextEncoding -> String -> Either EncodingException WindowsString Source #

Like toPlatformStringUtf, except allows to provide an encoding.

toPlatformStringFS :: String -> IO WindowsString Source #

Like toPlatformStringUtf, except on unix this uses the current filesystem locale for encoding instead of always UTF8.

Looking up the locale requires IO. If you're not worried about calls to setFileSystemEncoding, then unsafePerformIO may be feasible (make sure to deeply evaluate the result to catch exceptions).

Throws a EncodingException if encoding fails.

bytesToPlatformString :: MonadThrow m => ByteString -> m WindowsString Source #

Constructs a platform string from a ByteString.

On windows, this ensures valid UCS-2LE, on unix it is passed unchecked. Note that this doesn't expand Word8 to Word16 on windows, so you may get invalid UTF-16.

Throws EncodingException on invalid UCS-2LE on windows (although unlikely).

pstr :: QuasiQuoter Source #

QuasiQuote a WindowsString. This accepts Unicode characters and encodes as UTF-16 on windows.

packPlatformString :: [WindowsChar] -> WindowsString Source #

Pack a list of platform words to a platform string.

Note that using this in conjunction with unsafeFromChar to convert from [Char] to platform string is probably not what you want, because it will truncate unicode code points.

String deconstruction

fromPlatformStringUtf :: MonadThrow m => WindowsString -> m String Source #

Partial unicode friendly decoding.

On windows this decodes as UTF16-LE (which is the expected filename encoding). On unix this decodes as UTF8 (which is a good guess). Note that filenames on unix are encoding agnostic char arrays.

Throws a EncodingException if decoding fails.

fromPlatformStringEnc :: TextEncoding -> WindowsString -> Either EncodingException String Source #

Like fromPlatformStringUtf, except allows to provide a text encoding.

The String is forced into memory to catch all exceptions.

fromPlatformStringFS :: WindowsString -> IO String Source #

Like fromPlatformStringUt, except on unix this uses the current filesystem locale for decoding instead of always UTF8. On windows, uses UTF-16LE.

Looking up the locale requires IO. If you're not worried about calls to setFileSystemEncoding, then unsafePerformIO may be feasible (make sure to deeply evaluate the result to catch exceptions).

Throws EncodingException if decoding fails.

unpackPlatformString :: WindowsString -> [WindowsChar] Source #

Unpack a platform string to a list of platform words.

Word construction

unsafeFromChar :: Char -> WindowsChar Source #

Truncates to 2 octets.

Word deconstruction

toChar :: WindowsChar -> Char Source #

Converts back to a unicode codepoint (total).
