Hi all, this tiny goodie removes all entries without references from Undeclared. Maybe this should be called after every file in.

[ENH] new String modifier: String>>asPlural
by Norton, Chris 24 May '04

24 May '04

Hi Folks. Here's the preamble from my changeset: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "OK. You could say that this is a silly crusade, but I like my Squeak messages to be in proper English (at least when the language you're using is English). I was messing around with the HangMan file-in and I got a walkback that had the following title: 'Error: HangManPhrases classs are not indexable'. I just couldn't stand the extra 's' on 'class', so I created a nifty new String method called asPlural and I modified the sender of the odd string to use the new String modifier. Take it or leave it, but I think this makes auto-generated text just a little easier to read." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I hope you find this new String modifier useful too. Cheers! ---==> Chris <<PluralStrings-ccn.cs>>

[ENH] SerialPort, remember them?
by David N. Smith (IBM) 10 Sep '01

10 Sep '01

Hi: I've been playing with serial ports on my Powerbook G3 and I discovered some not so nice actions in class SerialPort. If the port is in use elsewhere, trying to open it gets a Primitive Error. I'd rather have my code get back some indication that the port didn't open, so I made some small mods to SerialPort, which are attached. Basically, primitives used during open answer nil if they fail, and the open method answers nil also. Dave _______________________________ David N.

[BUG] Socket assumes connection in Linux
by ajh18＠cornell.edu 26 Mar '01

26 Mar '01

When I do: Socket initializeNetwork. s _ Socket new connectTo: (NetNameResolver addressFromString: '127.0.0.1') port: 2001. It always returns a connected socket even when there is no socket listening on 2001. (s waitForConnectionUntil: Socket standardDeadline) returns true right away. It is not until I attempt to send data that its status changes from connected to otherEndClosedButNotThisEnd and an error is raised. I am the only one having Linux socket problems? Can anyone repeat this problem or the problem I posted on March 23 entitled "[BUG]Socket waits unnecessarily in linux"? Thanks, Anthony Image version: Squeak3.1alpha of 27 February 2001 latest update: #3848 VM version: Squeak3.1alpha of 27 February 2001 [latest update: #3776] for: unix

Need for 68K Mac VM?
by John M McIntosh 13 Mar '01

13 Mar '01

Since I'm building 68K versions of the macintosh 3.0.x VM and occasionally having issues with that I thought I'd ask does anyone really use or want to use it on a 68K machine, or could one live with earlier versions, 2.6, 2.7 or 2.8, mm even 2.9? One noticeable difference in 3.0 is that Morphic is really really slow on a 68K machine. The 3.0.5 mac VM I have lurking DOES run on a 68K mac with System 7.6.1, but does anyone care? Oh and lastly I do need a few folks that have 68K machines to alpha test... Seem some people who have done this in the past now no longer have old macs around. -- -- =========================================================================== John M.

Squeak slowdowns (Unix 3.1)
by Ned Konz 04 Mar '01

04 Mar '01

I'm using the 3.0pre2 Unix VM under Linux 2.4.0, with a 3.1 image. What I'm finding is that: * normally things run pretty well; if I do a Message Tally I see about 80% of the time being spent in Delay>>wait. The CPU usage is below 5% for Squeak. * sometimes, though, Squeak uses about 100% of a CPU, and if I do a similar Message Tally, I see 75% of the time being spent in EventSensor>>nextEventFromQueue. It can go from the "good" state to the "bad" state just by being left alone with no interaction. Saving the image, quitting, and restarting fixes this problem. Any suggestions? -- Ned Konz currently: Stanwood, WA email: ned(a)bike-nomad.com homepage: http://bike-nomad.com

who wrote PLay Writing?
by J Scott Jaderholm 02 Mar '01

02 Mar '01

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.

The descriptor in question is the one for the connection to the XServer. Now, that descriptor is registered with its own handler, so the sockets module doesn't need to deal with it. For the microseconds, that is handled by the central aioPoll() routine. -Lex
