toAbstractFilePathUtf :: MonadThrow m => String -> m AbstractFilePath 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.
toAbstractFilePathEnc Source #
Arguments
| :: String | |
| -> TextEncoding | unix text encoding |
| -> TextEncoding | windows text encoding |
| -> Either EncodingException AbstractFilePath |
Like toAbstractFilePathUtf, except allows to provide encodings.
toAbstractFilePathFS :: String -> IO AbstractFilePath Source #
Like toAbstractFilePathUtf, 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 EncodingException if decoding fails.
fromAbstractFilePathUtf :: MonadThrow m => AbstractFilePath -> 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.
Note that filenames of different encodings may have the same String
representation, although they're not the same byte-wise.
fromAbstractFilePathEnc Source #
Arguments
| :: AbstractFilePath | |
| -> TextEncoding | unix text encoding |
| -> TextEncoding | windows text encoding |
| -> Either EncodingException String |
Like fromAbstractFilePathUtf, except on unix this uses the provided
TextEncoding for decoding.
On windows, the TextEncoding parameter is ignored.
fromAbstractFilePathFS :: AbstractFilePath -> IO String Source #
Like fromAbstractFilePathUtf, except on unix this uses the current
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.
bytesToAFP :: MonadThrow m => ByteString -> m AbstractFilePath Source #
Constructs an AbstractFilePath from a ByteString.
On windows, this ensures valid UCS-2LE, on unix it is passed unchanged/unchecked.
Throws EncodingException on invalid UCS-2LE on windows (although unlikely).
mkAbstractFilePath :: ByteString -> Q Exp Source #
QuasiQuote an AbstractFilePath. This accepts Unicode characters
and encodes as UTF-8 on unix and UTF-16 on windows. Runs filepathIsValid
on the input.
packAFP :: [OsChar] -> AbstractFilePath Source #
Pack a list of OsChar to an AbstractFilePath.
Note that using this in conjunction with unsafeFromChar to
convert from [Char] to AbstractFilePath is probably not what
you want, because it will truncate unicode code points.
