SqueakMap - analysis tools?
by Bill Schwab 14 May '04

14 May '04

Hello all, SqueakMap seems to be taking off nicely, and it is a nice way to grab goodies. However, I still come back to the problem of starting from scratch. Dolphin's commercial origins force the issue with each release, but it's also a nice sanity check on whether or not I know what is in my image. Are there any good tools for deciding what to load into a new image? I encourage and Dolphin-using Squeakers to take a look at Migrate from my Dolphin Goodies - especially the version packaged for D5. I would really like to see something like it for Squeak. The other issue, mentioned before, is that SM seems to favor downloading over locally cached copies. Ideally, it should offer to download updates, but be willing to load packages from the local drive. Has that been addressed? Bill Wilhelm K.

HELP! with plugins
by Eric Scharff 11 May '04

11 May '04

(Apologies for nagging folks again, but I never received answers to any of my plugin questions. While creating plugins may not be nearly as exciting as discussing licensing issues, it is far more important to my current project. :) ) Here is a re-post of my latest plugin question: I have a trivial plugin: TestInterpreterPlugin subclass: #MyPlugin instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Eric-Test' With a "primitive" method I intend to compile to C: innerLoopX: x y: y limit: escape | | self primitive: 'primGuy' parameters: #(SmallInteger SmallInteger SmallInteger) receiver: #Oop. ^ (escape + x + y) asOop: SmallInteger (Note, simplified to do nothing useful, but illustrates the problem) If I execute: MyPlugin doPrimitive: 'innerLoopX:y:limit:' withArguments #(1 1 1) I would expect to get 3. Instead, I get a walkback: Error: attempt to index non-existent element in an ordered collection OrderedCollection(Object)>>error: OrderedCollection>>errorNoSuchElement OrderedCollection>>at: InterpreterProxy>>stackValue: InterpreterProxy>>stackIntegerValue: MyPlugin>>DoItIn: Compiler>>evaluate:in:to:notifying:ifFail: [] in TestTMethod>>simulatePrologInContext: Array(SequenceableCollection)>>keysAndValuesDo: TestTMethod>>simulatePrologInContext: MyPlugin(Object)>>primitive:parameters:receiver: MyPlugin>>innerLoopX:y:limit: MyPlugin class(TestInterpreterPlugin class)>>doPrimitive:withArguments: What am I doing wrong? -Eric

Enhanced & Extended Serial Port support.
by John M McIntosh 11 May '04

11 May '04

I've push a changeset and macintosh plugins onto the server, they should appear in a few days. The SerialExtendedMacOS9Plugin.sit goes in the mac 3.5 noncarbon plugin location The SerialExtendedUnixPlugin.bundle goes in the mac 3.5 carbon plugin location {yes the name implies unix, but os-x is unix...} The EnhancedSerialPorts-JMM changeset which is the classes and plugin interface logic you need to file in. I suspect usage will be limited but it enables you to do things with serial ports (and file handles, hint any file handle) that you can't do otherwise. I would think to compile this code on your favorite Linux box that would be a snap. Only one platform specific primitive or method exists serialPortFindNamesPlusKeysstorage which on os-x invokes the IOServiceGetMatchingServices() call to get path names to devices that support the serial protocols. This primitive call a common Linux box could be replaced by smalltalk code to iterate over /dev or read some sort of control file etc to figure out the path names to the serial devices. For mac os-9 this functionality was already part of the VM. I'm hoping that no platform specific C code will be required for unix boxes. Alas windows users require someone to do the dirty work if you want windows specific serial calls? Or will unix emulation somewhere/how etc work? Couldn't speak for parallel ports, never even occurred to me to investigate till now. I should point out that Dan Ingalls <Dan(a)SqueakLand.org> was kind enough to actually fund with real USA $ some of the work required to build this plugin, then willing to release it to the public. So enjoy, and thank Dan for motivating ($) me to write the code and for releasing it. PS I won't pass up an opportunity to point out if you've an obscure macintosh specific feature you would like and like Dan have a bit of cash to pay for it, then we should talk. -- ======================================================================== === John M.

[BUG][3.6] Resignalling an exception
by Avi Bryant 11 May '04

11 May '04

Try the following line of code in both 3.5 and 3.6: [1/0] on: Error do: [:e | e signal] In 3.5, when the debugger comes up, the top context is the send to #/. In 3.6, it is the handler block, with the send to #/ several frames down. Which is correct? I personally much prefer the 3.5 behavior. Another symptom of what I think is the same bug: [1/0. self inform: 'inner'] on: Error do: [:e | e defaultAction. self inform: 'outer']. Try this code. When the notifier pops up, click Proceed. In 3.5, you will see 'inner'. In 3.6, you will see 'outer'. Again, I would prefer the 3.5 behavior here. Does anyone know what exactly has changed, and how easy it is to fix?

[ANN] Preview of Squeak interface to wxWidgets
by Rob Gayvert 03 May '04

03 May '04

Greetings, I have posted a snapshot of my efforts to blend Squeak with the wxWidgets GUI library. Downloads are available at http://homepage.mac.com/rgayvert/wxsqueak.html. Notes: - Currently Win32 only - Wrapper methods are implemented only for core framework and demo classes - Uses version 2.5.1 of the wxWidgets library - Supports (in theory) most of the wxPython API - Uses synchronous callbacks to Squeak via interpret() - Built using a single internal plugin - Most of the plugin methods are generated by parsing the wxWidgets docs - Uses a modified VM (minor tweaks to ioProcessEvents() and interpret() are needed to provide synchronous callbacks to wx events). Any comments or suggestions are appreciated. .. Rob

[Q[ What is the correct VM for OS X 10.3.3 ?
by Lic. Edgar J. De Cleene 02 May '04

02 May '04

John: This morning I have a meeting with local Apple Dealer Mario Verardi and try to get Squeak working in latest 10.3.3 without success. I remember something you say about a problem in this version and what we must send mail to Apple. What I don't know is if this was fixed by you , what the correct VM is or what steps we must follow to have Squeak working in 10.3.3. Very, very thanks in advance. Edgar

RE: can't load updates
by Richard Staehli 01 May '04

No luck. That is the out of box preference. I get the same result with either server option. Also, opening the package browser complains it cannot contact any SqueakMap server. This is on a PowerBook G4 running /Users/rstaehli/Squeak3.6-MacOS-Full/Squeak 3.6.1Beta5.app/Contents/MacOS/Squeak VM Opt -psn_0_9961473 On Friday 30 April 2004 Ned Konz wrote: > On Friday 30 April 2004 9:24 am, Richard Staehli wrote: > > I am trying to upgrade to 3.7a, but am having no end of problems. > To >start, I have downloaded Squeak3.7a-5816.image and run it.
