running directly from RAM on wince?
by Craig Latta 28 May '01

28 May '01

Hmm. Would it be possible to run the image on wince from where it sits in "storage" RAM, without copying it into "program" RAM? It seems a shame to use twice the space. I'm willing to give up the integrity of a snapshot after startup (as long as I can still make another snapshot). Can iPAQ/Linux Squeak do something clever in this regard? thanks, -C -- Craig Latta composer and computer scientist craig.latta(a)netjam.org www.netjam.org crl(a)watson.ibm.com Smalltalkers do: [:it | All with: Class, (And love: it)]

Re: [ENH][GOODIE] CommandWindow V1.1 (new release)

Ok, I'm convinced. Got that, got OSProcess 2.1, don't have the plugin. Anyone got a binary .so handy? thanks. "David T.

Yes. As an experiment, edit your .xinitrc to start up Squeak as the "window manager". If you have OSProcess and CommandWindow loaded, you will find that the only thing really missing is the code which would put a SystemWindow frame around the X programs. Well, I'm oversimplifying, but you'll get the idea as soon as you look at it. The best bet would be to dig up the C source code for the the simplest possible X window manager (twm perhaps), and move the key functions into Squeak. Note that an X window manager does not require OSProcess, and does not need to run on Unix; it just needs to be able to talk to an X window server over a socket connection. Any volunteers? Dave

Embedding Squeak in REALbasic?
by Aaron J Reichow 28 May '01

28 May '01

Has anyone ever thought about embedding Squeak into REALbasic? REALbasic an OO BASIC development environment for Mac OS, that can compile to Mac OS and Windows. It's quite Mac-ey and allows rapid development of nicely native apps. (I've never worked with deployed Windows apps, but they're pretty nice on Mac OS) I've been pondering this for a while, thinking that Squeak and REALbasic could be tied together some how to give Squeak a native face without having to write plug-ins for native interfaces, as well as having to re-write existing tools code or messing around with PluggableViews. This has come up in my mind quite a few times, when faced with a need to write a quick and dirty app that I *could* do in BASIC, but it's more naturally done in my head in Smalltalk, but requires some degree of native look-and-feel. (In this case, dragging and dropoing files from the Finder) Musings?

Hi, Dave. Just wondering - What do you do with it? It seems like I should be the classical user (always having open one squeak and one terminal). "David T.

[EXPERIMENTAL!][ENH] FocusFollowsCursor.cs
by Ram Krishnan 28 May '01

28 May '01

Here's a simple hack to change the default keyboard focus policy in Morphic projects. I've not tested this very extensively, so please take the usual precautions to safeguard your Squeak image. -ram "Change Set: FocusFollowsCursor Date: 28 May 2001 Author: Ram Krishnan Experimental!! A simple hack to make keyboard focus follow the mouse cursor replacing the default 'click to type' focus policy of Squeak. This hack only works with Morphic SystemWindows and has no effect on MVC windows. This ChangeSet has only been tested (minimally) with Squeak 3.0."!

(Except in the same sense that a district plan filed in an office at Alpha Centauri is a source of information for people resident on Earth.) My newsfeed has been essentially unusable for so long that I haven't read news for over a year. (Tried again last week. Still unusable.) I wish people would understand that additional places to have to look at are BAD. (Backups are a great idea. 100% identical duplicates are a good idea. But bits here and bits there are a great way to soak up lots of time, having as much fun as if someone were slapping you with an octopus.) I see no problem with the mailing list being copied to a newsgroup and vice versa as long as it's absolutely 100% both ways.

pending file primitives (EH?)
by John M McIntosh 28 May '01

28 May '01

Since I'm fiddling with file primitives I'd better ask. Are we missing something at the primitive layer? At this point we should be able to open, close, read, write, seek, truncate, and flush. Soooo what have we forgotten? -- -- =========================================================================== John M.
