It's available at the usual place: http://srfi.schemers.org/srfi-68 Here are the most important changes: - The "byte" terminology was changed to adhere to SRFI 4 / SRFI 66. - The various INPUT-xxx (and READ-xxx) procedures all return #f now. (Instead of an empty octet vector or string.) - OUTPUT-U8VECTOR-N and OUTPUT-STRING-N are gone; their functionality is subsumed by OUTPUT-U8VECTOR and OUTPUT-STRING and optional arguments. - The procedures for opening files for output now accept a file-options argument. - Procedures for opening files simultaneously for input and output were added. - Output translation procedures are called upon close with #f as the data object. - A transcoding infrastructure was added to abstract over the details of the translation procedures, and to provide common text encodings and standard CR/LF translation. - MAKE-I/O-BUFFER was added as a front end to MAKE-U8VECTOR. - The ports layer and its specification were restructured in such a way that they're usable and understandable without the two layers below. This allows Scheme systems to implement only the ports layer, or only the ports layer and the imperative layer. Moreover, it allows Scheme systems to represent ports by something other than reference cells to streams. - MAKE-STANDARD-INPUT-STREAM, STANDARD-OUTPUT-STREAM, and STANDARD-ERROR-STREAM were added to the streams layer. - INPUT-U8VECTOR-N!, INPUT-STRING-N!, READ-U8VECTOR-N!, and READ-STRING-N! were added. - Some obviously forgotten procedures were added: OPEN-WRITER-OUTPUT-STREAM, CALL-WITH-CURRENT-OUTPUT-STREAM, CALL-WITH-CURRENT-ERROR-PORT, OUTPUT-PORT-BUFFER-MODE, SET-OUTPUT-PORT-BUFFER-MODE!. I hope y'all like the changes---I've mostly tried to follow the suggestions people have made. (Which were very helpful so far---keep 'em coming!) -- Cheers =8-} Mike Friede, Völkerverständigung und überhaupt blabla
