tryTokReplace :: String -> ByteString -> ByteString -> ByteString -> Maybe ByteString Source #
tryTokReplace tokChars old new input tries to find the token old and
replace it with the token new everywhere in the input, returning Just
the modified input, unless the token new is already in the input in
which case Nothing is returned. A token is a sequence of bytes that match
the class defined by tokChars. This function is supposed to work
efficiently with large inputs i.e. whole files.
forceTokReplace :: String -> ByteString -> ByteString -> ByteString -> ByteString Source #
forceTokReplace tokChars old new input replaces all occurrences of
the old token with the new one, throughout the input.
annotateReplace :: String -> ByteString -> ByteString -> ByteString -> Bool Source #
Check if a token replace operation touches the given line.
breakToTokens :: ByteString -> [ByteString] Source #
Break a Bytestring into tokens, according to defaultToks,
discarding non-tokens.
defaultToks :: String Source #
