[Pharo-project] [NativeBoost] New update available

by Igor Stasenko

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.

[Pharo-project] Hacking afternoon starts

by StÃ©phane Ducasse

Hi guys we are starting and we will log on irc but you can also reach me with aol/ichat: sducasse(a)mac.com ICQ: 234273866 the idea is to - fix some bugs in 1.1 - tristan found the problem in the weakDictionary so we will need other people to have a look at it. - integrate/check validate some easy items for you - fix some important bugs. I suggest that we send around mails in this thread when we start to work on an item and we integrate something. In the future we will see if we cannot use the inria infrastcuture to have webcam + videos fun. Stef

Re: [Pharo-project] ConfigurationOfPharo

by Torsten Bergmann

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.
