Hi Marcel, Those are some worthwhile criticisms. If you post them on the webteam list, then there will be a record of them in a place where they can be of some use. Thanks, Chris

SqueakNOS on Raspberry Pi
by askoh 24 Mar '14

24 Mar '14

http://tessel.io/ is building a microcontroller running pure JavaScript - no OS. Can we have pure Smalltalk running on Raspberry Pi or equivalent? How hard would it be? Is SqueakNOS a candidate for that?

What happened to the old #mouseHold: events?
by tim Rowledge 24 Mar '14

24 Mar '14

Back in the Old Days of squeak… um, 3-ish?, we used to have an event named #mouseHold: that was triggered if the mouse button was held do for longer than 6650mS without being released. The old Scratch code has been using that to provide one way of popping up a menu. T’ain’t there no more. There *is* #doubleClickTimeout: but that relies upon the button being released or there not being a drag selector in use. I’m more than a bit conflicted about even trying to replicate the functionality since you have to not move the mouse during the time interval, and mixing the gestures for select and menu makes me squirm a bit. On the other hand, it’s what’s expected in this case and I don’t want to disappoint users. Generally I’m also little surprised to see how many cases in MouseClickState>handleEvent:from: actually send the double click timeout event - it’s hard to see what it is expected to be used for with no exemplars or comments to hand. Does anyone recall any reasoning behind the changes? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: RPSW: Randomize Program Status Word

Should class comments be separated from source code?
by liang bing 23 Mar '14

Should class comments be separated from source code? I think it should be separated into two files, the reasons are, 1. current comment not enough for understood (less or nothing) 2. if I added new comment , it is not convenient when update or load new packages 3. comment is knowledge about how to use, how to change the application, it could be shared and accumulated 4. comment should be stand alone as knowledge base with different local languages I hope Squeak 4.6 gives a new comment tool in system browser Three files: Soure file, Changes and Comments file, Hope Squeak better!
