[ENH] Bold Comments
by Bert Freudenberg 02 Nov '00

02 Nov '00

Hi folks, I just commented a method, which was not too long, but still needed some explanation. After I was done, it looked sooo much more difficult than before - because the comments visually melt into the code ... Instead of throwing the comments out again, I came up with this, which does not require pretty printing. Enjoy! "Change Set: boldComments-bf Date: 2 November 2000 Author: Bert Freudenberg Makes comments stand out when browsing. I chose bold because the bold fonts look better than italics, and bold is ignored when accepting a method." Preferences enable: #boldComments!

Speaking of the VR3, the following interesting tidbit was posted onto comp.sys.newton.misc today: The special VR3 developer units, appropriately dubbed the "VR3 Developer Edition," will come equipped with 16MB of internal Flash memory instead of the usual 2-8MB Flash, and will also have 8MB of RAM memory. The VR3 is based on a 66MHz 32-bit NEC VR4181 MIPS system-on-chip processor. For display, it has a 240 x 160 pixel monochrome LCD touch screen with 16-level gray-scale and a 3.25" x 2.25" viewable area. The VR3 Developer Edition which, according to Brantley, is "a $249 value," is being made available to Agenda Developer Program members for "just $179" (plus applicable tax and shipping). More news at: http://linuxdevices.com/news/NS8043418131.html Shame I've run out of excuses to buy new toys... (Newton 2100... yeah, I need one of those... Helio- hack value, yeah, that's the ticket...) ANyway, great work, Jay! Aaron

Re: Help with Multilingualized Squeak (was: Re: Celeste withGerman Umlaute)

Hello, Bernhard I took charge of the part of Celeste in M17n Squeak(CelesteJ). CelesteJ is supporting only Japanese now. I think that the current status of CelesteJ is pre-alpha.

Sorry, CelesteJ does not support MIME header encoding now.

M17n Squeak remaps glyphs of a StrikeFont(NewYork) from Sqeuak specific (MacRoman) to ISO-8895-1. But the keycode that returned from InputSensor>>primKbdPeek and primKbdPeek is MacRoman. > What would have to be done to fix those problems? Do I need a different font > with the right encoding? Or should the problem be fixed somewhere else, in > ParagraphEditor or InputSensor? You see, I am not sure what the right design > is here. As always, any help is appreciated. Please try the attached patch. The patch converts the keycord from MacRoman to ISO-8895-1. -- Kazuhiro Abe abee.abe(a)nifty.ne.jp

I am seriously planning on using a Helio running Squeak in MicroSeeker instead of a Palm running Pocket Smalltalk (especially given PST's lack of performance...) Since the current autonomous controller is written in Squeak, it should make the port pretty simple :-) Later, Jon -------------------------------------------------------------- Jon Hylands Jon(a)huv.com http://www.huv.com/jon Project: Micro Seeker (Micro Autonomous Underwater Vehicle) http://www.huv.com

Ahh... one more test as a guess as to why you aren't getting it. After starting my image, I created a normal morphic project (not a "morphic world"), entered it, selected "previous project" (back to the default MVC world), then did the above. *no* walkback. So something is being set by entering *some* Morphic project that carries forward to eliminate this error with a Morphic World. -- Randal L.

>The first example in project "Play With Me 8" no longer works after update >#2876. The real source of the problem is unknown. MIDIScores now expect the ambientTrack to be initted, and PWM8 had a call that did not init this vairable. >Solution: use the method ambientTrack instead of the variable. Your fix is now in the update stream (along with a fix for the init as well). Thanks - Dan

[ENH]MPEGPlayerMorph (0.4)
by Karl Ramberg 01 Nov '00

01 Nov '00

Attached is a very basic MPEGPlayerMorph It has currently three buttons: Open: opens a menu so you can locate a mpeg/mp3 file and select it, and then starts executing what ever it is. Stop: stop playing the stream (s). Play: Plays the stream (s) from beginning. Also added is a progress bar, so you can see how much is remaining of the song/video :-) Please enhance this more ! Karl (0.4) Added everyones favorite: LedCharacterMorph, so now the title of the song is diplayed in true retro fashion! To do: Slider instead of progress bar so one can slide back and forth:-) Play button resumes where stop was pressed. Fast Backwards, Fast Forward, Jump to start buttons. More and more:-)

Re: [VM] Hooks from module into platform support code?

Take a look at how SocketPlugin & SoundPlugin do it (well, the sqUnixBlahBlah files for those plugins) - basically you can set a global var in the moduleInitialise and (ab)use the ability of the linker to connect it properly. Check the aioPoll in sqXWindow.c to see how the polling is then done. Personally I prefer to have a callback function (that's what the examples in the default 'platforms.export' illustrate) to do this simply because it feels cleaner. Ian prefers the direct approach. The disadvantage is that you still have to modify the sqXWindow.c to add the call to the function; some time ago there was some discussion about how to register functions for this stuff, but since sockets and sound (the two current usages) require quite different arguments it seemed to be a bit tricky. I guess it might be useful to have the general registry you suggest for most cases and perhaps accept that sockets can't work that way. tim
