Hi there, I am still working my way through MultiByteFileStream tests, and have come across the messages #converter and #converter: . I would like to be able to test these - could someone explain briefly how the converters are used in this class? Many thanks, Sheridan

I would like to be able to test these - could someone explain briefly how the converters are used in this class? In order to convert from bytes to characters and vice versa, MultiByteFileStream uses a TextConverter subclass instance as a helper. The messages #nextFromStream: and #nextPut:onStream: are the main interface between the two. The silly thing is that both MultiByteFileStream and TextConverter convert from wrongly encoded strings to correctly encoded strings. ZnCharacter[Read|Write]Stream and ZnCharacterEncoder do the correct thing. Sven |

This guy is loudly crying for a decorator. I wonder when Xtreams could be pushed...
So it corrects encodings? :P I didn't know that! They are flawless!!! ZnCharacter[Read|Write]Stream and ZnCharacterEncoder do the correct thing. |

could we not nuke MultiByteFileStream and use ZnCharacterStreams?

Yes, one day we have to do this.
There is also Xtreams which is a broader, more interesting way of rethinking the subject. But the main issue is: the stream API is way too broad, so any change will involve slimming down or changing the API and hence the users. That is a lot of work. > On 18 Dec 2014, at 23:51, stepharo <[hidden email]> wrote: > > Sven > > could we not nuke > > MultiByteFileStream > > and use ZnCharacterStreams? > > > Le 17/12/14 19:54, Sven Van Caekenberghe a écrit : >>> On 17 Dec 2014, at 19:42, [hidden email] wrote: >>> >>> Hi there, >>> >>> I am still working my way through MultiByteFileStream tests, and have come across the messages #converter and #converter: .

Could you think about a roadmap?
Because we are doing often actions that require a lot of work but people do not notice it.
