who wrote PLay Writing?

Hi, Who wrote the play writing project on Bob's Swiki? I am running the latest 3.1 and if I click on the scriptingBench area I can type one character and then it deselects it. So in order to enter whole words I have to click the field for each letter. Also, I'd like to record my "play" to a wave or something. How do I do this? I pulled up the RecordingControlsMorph and click record but I get this error 28 February 2001 4:20:59 pm Error: a primitive has failed SoundRecorder(Object)>>error: SoundRecorder(Object)>>primitiveFailed SoundRecorder>>primStartRecordingDesiredSampleRate:stereo:semaIndex: SoundRecorder>>startRecording SoundRecorder>>resumeRecording RecordingControlsMorph>>record [] in SimpleButtonMorph>>doButtonAction BlockContext>>on:do: [] in BlockContext>>valueUninterruptably BlockContext>>on:do: [] in BlockContext>>valueUninterruptably BlockContext>>on:do: BlockContext>>valueUninterruptably BlockContext>>ensure: CursorWithMask(Cursor)>>showWhile: SimpleButtonMorph>>doButtonAction SimpleButtonMorph>>mouseUp: SimpleButtonMorph(Morph)>>handleMouseUp: MouseButtonEvent>>sentTo: SimpleButtonMorph(Morph)>>handleEvent: SimpleButtonMorph(Morph)>>handleFocusEvent: HandMorph>>sendFocusEvent:to: HandMorph>>sendEvent:focus: HandMorph>>handleEvent: HandMorph>>processEvents [] in WorldState>>doOneCycleNowFor: I'm running squeak under linux with squeak3.0 pre1 vm..if there's anything else that would be helpful just let me know.

RE: [GOODIE] NK-ConnectorsDemo.012.pr on Bob's Super Swiki

Ned, What has changed in your ConnectorsDemo after about version .009? I think I tried it about there and things seemed pretty responsive, but in later versions (14, 17) my system starts to crawl when I'm in the connectors project. The cursor hesitates as it moves over Morphs and when I go to drag them around, the movement is very sluggish? BTW, I love the Connectors!

[PROBLEM] code generation & processes???
by Elzbieta Chludzinska 02 Mar '01

02 Mar '01

The following code fragment is inside of a loop which is forked as a Process. It is part of a parallel simulation, in this case 2 images executing the models in the sim. When I execute the sim with this code in fails to #send:to: the #NULL Event. lastNow = now ifFalse: [self cOut keysAndValuesDo: [:k :v | v ifFalse: [Daemon singleInstance send: (PackingData pack: (Event time: now + self lookAhead type: #NULL from: self mid to: k << 8 + 1)) to: k. self nullMsgSent: self nullMsgSent + 1]. lastNow _ now]]. If I change the above code to the following: lastNow = now ifFalse: [self cOut keysAndValuesDo: [:k :v | v ifFalse: [self nullMsgSent: self nullMsgSent + 1. Daemon singleInstance send: (PackingData pack: (Event time: now + self lookAhead type: #NULL from: self mid to: k << 8 + 1)) to: k ]. lastNow _ now]]. the sim RUNS! ALL I've done is to move the single line: self nullMsgSent: self nullMsgSent + 1. from the beginning of the loop to the end of the loop. nullMsgSent is just an instance variable used as a counter and plays NO role in the logic of the code. Any ideas why? Could this be a problem in the code generation? Could this be a problem with ProcessScheduler? Elzbieta

Are you asking if I have any new ideas for the editor, or are you saying you have new ideas? What I'm working on right now: * reverse-engineer class diagrams from Smalltalk code: * choose "Add class", pick a class (or perhaps choose from Browser class-list menu). * this makes a UML class representation (a NCTextRectangleMorph) with instance variables and methods filled in * when dropped into the world, connects itself to other UML class representations in the world (just generalization relationships right now, though I'm interested in type inference to get interface specs). * write code for finite-state machines from diagrams: * traverse state diagram objects in the world (will make a subclass for these, or mark them using a property). Generate code based on a template (or based on the operations in a generator class). Look at my NCFiniteStateMachine class for one target. Do you have any other ideas? -- Ned Konz currently: Stanwood, WA email: ned(a)bike-nomad.com homepage: http://bike-nomad.com
