Hello everyone I am trying to use Pharo 7 for my project and I noticed that most of my streams related code does not work anymore. Reason is that API for streams received from writeStream of FileReference changed and I think it changed for the worse in my case, because << does not properly handle any other objects than strings anymore. In both Pharo 6 and 7 I can write String streamContents: [ :s | s << 'hello' << 42 << $! ]. and get 'hello42!'. I can write in Pharo 6 but cannot in Pharo 7 'hello.txt' asFileReference writeStreamDo: [ :s | s << 'hello' << 42 << $! ] In Pharo 6, I get same result in both examples (written to the file in second case of course), but in Pharo 7, the second example results in exception because << does not work with anything other than strings, so it seems I have to manually convert everything to strings. This change to streams seems to me like a setback for 2 reasons: 1) API amongst streams is no longer consistent in this case 2) streams for files lost useful functionality and to make my project compatible with Pharo 7, I have to make lots of effort to make my code uglier and longer I would like to ask for the reason of this change and whether is there anything that can be done with it. Or do I just misuse or misunderstand anything? Thank you. Best regards, Jan -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
