RE: Squeak API Library question from a Newbie
by Alejandro F. Reimondo 23 Feb '98

23 Feb '98

I think that you are using an old VM interpreter with the last version of the API .st files. Provably you have a conflict between VM interpreter version and Smalltalk code. Steps to be done for a secure building of API framework: 0.- Download the API framework from http://www.sugarweb.com/miniatures/files/sqApi13.zip 1.- Start your favourite (clean) image. 2.- FileIn the file: API FileMeIn.txt 3.- Save the image. Now you have included all the Smalltalk changes; but you must rebuild the virtual machine to include primitive services. 4.- Build the interpreter source file evaluating: VirtualMachineSourceBuilder current plugAll;deleteFile;translate >>>*WARNING* The new interpreter source file will be saved with name Interp.c and C project MUST be changed to compile this interpreter file and NOT the original file! (it can be the source of your problem) >>> 5.- Be sure that you include all the source files in your project to compile the VM. verify the inclusion of: interp.c and: sqWin32API.c 6.- Compile the VM. 7.- Run the new VM with the last saved image. 8.- Evaluate startUp expressions each time you restart the image. ExternalHandle startUp. CallBack startUp. 9.- Now you can evaluate the test scripts. Notes on preceding topics: 1.- Be sure that you does not mix framework versions. API framework has been refactored and is not secure to fileIn new version over and old. 2.- Can take a looong time on some machines. 3.- Save the image with the test script window open. 7.- You can compile and debug placing a breakpoint in the primitive 241 to see what is happening. Place the breakpoint in C source code in file interp.c function: primitiveExternalFunctionService() Hope this points on rebuilding the VM will help you. Feel free to post me if you have more questions. Ale. ---------- Desde: Dave Anderson[SMTP:deandrsn@uiuc.edu] Enviado el: Lunes 23 de Febrero de 1998 12:34 Para: squeak(a)cs.uiuc.edu Asunto: Squeak API Library question from a Newbie I will happily admit that I am a squeak Newbie. That said: I am trying to get Alejandro F. Reimondo's API library to work. I have tried the 1.23 version (which comes with a sq.exe binary). But I keep running into doesNotUnderstand messages when GetModuleHandle was being called on KernelDLL. While trying to figure out that problem, I ran across the post that a 1.3 version was available. So I grabbed that version and, since it did not come with a binary, proceeded to compile in the sqWin32API code (with the 1.3 windows source of course). However, after I file in the API st files, I try to initialize the libraries with ExternalHandle startUp. Now, instead of getting a doesNotUnderstand. I get a primitive failure, which is happening when primitive 241 gets called with an argument of 2, which is calling the GetModuleHandle code. Has anyone run into this problem. Any help would be greatly appreciated. Dave Anderson cs225ta1(a)cs.uiuc.edu

Various translation problems
by Philippe de Rochambeau 23 Feb '98

23 Feb '98

I am having problems translating the following snippets of code in the "Duckling" example in Lalonde's "Inside Smalltalk II": 1) erase "I erase myself by whitening the area occupied by my icon." Display white: (position extent: icon extent). should "white:" be replaced by "fillWhite:"? 2) "Next, create a mother duck with a bigger icon." mother := self new. " mother icon: (ducklingIcon magnifyBy: 2@2). what should I replace "magnifyBy" by? 3) [The following initialize method shows how duck bitmaps are created and their extent defined during initialization. See below] initialize "MotherDuck initialize" "Older implementation definitions" DuckIcons := (1 to: 7) collect: [:index | Cursor perform: (#(origin corner crossHair up down read write) at: index)]. DuckIconMenuNames := ('left corner\right corner\cross hair\up arrow\', 'down arrow\eyeglass\pen writing') withCRs. "Newer implementation definitions." DuckIcons := Array with: (Form extent: 50@50 fromArray: #(0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1536 0 0 0768 0 15 57344 896 0 31 61440 390 0 56 6144 204 0 48 3072 220 0 97 33792 112 0 103 58550 240 0 480 512 176 0 1008 768 432 0 3888 480 864 0 16368 496 544 0 7984 26 608 0 2032 15 1568 0 510 5 33888 0 127 35840 60512 0 3 50688 14528 0 0 59136 4544 0 0 29568 384 0 0 12672 384 0 0 12480 12672 0 0 6368 29056 0 0 7291 50048 0 0 3135 33536 0 0 1567 1792 0 0 1792 1536 0 0 768 3072 0 0 896 7168 0 0 449 61440 0 0 255 57344 0 0 63 0 0 0 6 0 0 0 6 0 0 0 6 0 0 0 6 0 0 0 15 0 0 0 31 32768 0 0 58 49152 0 0 50 24576 0 0 34 24576 0) offset: 0@0) with: (Form extent: 50@50 fromArray: #(0 0 0 0 0 511 0 0 0 2047 49152 0 0 7681 6144 0 0 30720 61440 0 1 49152 30720 0 3 32768 7198 0 7 0 3584 0 6 0 1536 0 6 0 768 0 12 15360 768 0 24 65024 62336 0 25 50947 63872 0 57 37639 7360 0 49 14726 20160 0 49 64900 59072 0 113 65415 63072 0 96 1793 65120 0 96 0 3680 0 224 248 32 0 224 49151 32 0 199 63503 57376 0 511 1 63536 0 504 0 15408 0 448 0 3888 0 384 0 944 0 128 0 992 0 128 0 224 0 192 0 192 0 64 0 384 0 96 0 768 0 33 0 1536 0 49 57408 3072 0 17 61560 6144 0 24 124 12288 0 24 0 24576 0 12 0 3 49276 0 0 3 49368 0 0 6 24972 0 0 6 26380 0 0 12 15372 0 0 12 14348 0 0 12 4100 0 0) offset: 0@0) [etc] ======= the "quack" instance method contains the following line of code: iconOffset := self icon extent // 2.

My bet is that Ward would be happy if someone would take it upon themselves to add to his Wiki in the way that you describe. Actually, if you search for the topics discussed on this mailing list, you'll find that most of them have actually made their way into Ward's Wiki already. My Swiki could be used for this, too, but I think that the critical mass of Squeak content is already in Ward's Wiki.

I don't think this exists (also it would be illegal since it would break all sorts of copyrights.) Also it's out of print although you MIGHT be able to get one thru amazon.com.

Does anybody have an online version of 'A taste of Smalltalk.' I cant find the book anywhere (probablye cause I live in Mexico).
