Hi Serge, nice demo! Looking through the slides in "Build you own control structure" you use #ifSeven: as example which is easy, but not a "real world use case". I typically use another example: In a few languages you have a "REPEAT (block) UNTIL (cond)" control structure (in Pascal for instance) which is easy to add to Smalltalk with a #repeatUntil: method on BlockClosure.

[Pharo-project] SqueakSource question: how do you make new lines in project description?
by Igor Stasenko May 1, 2010

May 1, 2010

On a project like: http://www.squeaksource.com/Alien.html the project description contains a nicely formatted text. But in my project, no matter what i input in project description field, it squashing to a single paragraph, removing any new lines.. What i am doing wrong? -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] Question about dragging an image into the vm in Windows
by Mariano Martinez Peck April 30, 2010

April 30, 2010

Hi folks. It has been asked a problem in Pharo mailing list and I wanted to ask you. The summary is this: - You are allowed to take a .image and drag it into a vm (.exe) and this will run the VM with the dragged image - In such case, the image is interpreted as systemAttribute 1 The problem is when you define a image in the ini file. Suppose I add this to my ini file: ImageFile=Contents\Resources\Pharo-1.0.image Then, if I try to drag and drop another image to the VM, there will be an UTF8 input error as the thing that I dragged (the image) is interpreted as systemAttribute 2 and thus, in the method startUpAfterLogin it seems systemAttribute 2 is the sources file. So, it tries to load such file as if it were a text file, but as it is an image file...then the error. The ideal would be: if I have defined a image in the file, to be allowed to drag another one. Of course, the one I drag should be used and set as systemAttribute 1. Do you know how can I do that? is this fixable ? In other hand, maybe I can do a validation and a nice error message in case the above cannot be done. Thanks Mariano

Re: [Pharo-project] ConfigurationOfPharo

The best solution would be to bring back Damiens version that was deleted so the repos is like it was before without any compatibility problem (maybe someone has it in it's package cache). We should also remind people not to delete mcz's.

[Pharo-project] [NativeBoost] New update available
by Igor Stasenko April 30, 2010

April 30, 2010

Hello all. The main direction of work during last days, were introducing a new function formal specification format. With new format, NativeBoost jumps on a next level of flexibility and much less error prone to use!! Here is the old format: primGetModuleFileName: hModule with: lpFileName with: nSize <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ NBFFICallout apiCall: #(DWORD 'GetModuleFileNameA' ("in" HMODULE "out"LPCSTR "in"DWORD) ) module: #Kernel32 options: #( - coerceNilToNull ) and here is new: primGetModuleFileName: hModule with: lpFileName with: nSize <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ NBFFICallout apiCall: #( DWORD GetModuleFileName ( HMODULE hModule, LPTSTR lpFilename, DWORD nSize)) module: #Kernel32 options: #( - coerceNilToNull ) A new format matching very closely to C syntax.. so , for most C functions you can just do a copy-paste! Also, see that formal spec includes an argument names. They are not a dummy ones, but instead should match the argument names of method. In that way, the formal spec can check the argument names and also, takes in account their order on ST stack. So, you can push arguments in different order as you specified in smalltalk method. But that's not all. Besides a formal argument names, a new format also accepts constants , instance variables and special variable - self. Here: alloc: numberOfBytes <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ NBFFICallout apiCall: #( LPVOID HeapAlloc (self , 0 , SIZE_T numberOfBytes) ) module: #Kernel32 a windoze function takes 3 arguments LPVOID HeapAlloc( HANDLE hHeap, DWORD dwFlags, SIZE_T dwBytes ); but your method takes just one, while other two is 'self' and 0 constant. Instead of just integer literal, you can also use a class variables or pool variables, to make things more convenient and readable: zalloc: numberOfBytes "same as #alloc: but additionally zero-fill the allocated memory" <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ NBFFICallout apiCall: #( LPVOID HeapAlloc (self , HEAP_ZERO_MEMORY , SIZE_T numberOfBytes) ) module: #Kernel32 And the last thing, is instance variable access. Point>>nbX <primitive: #primitiveNativeCall module: #NativeBoostPlugin > ^ NBFFICallout cdecl: #( sbyte (long x) ) emitCall: [:gen | gen asm pop: gen asm EAX ] here, primitive reads x ivar of Point instance, as a 'long' C value, but on return, converts it to a signed byte value, so: (127@5) nbX 127 (128@5) nbX -128 (-200@5) nbX 56 (5000@5) nbX -120 P.S. Thanks Henrik for a suggestion to change the format! It is now roxxx! :) -- Best regards, Igor Stasenko AKA sig.
