Re: [Pharo-project] Hierarchy browsers & implementers of
by StÃ©phane Ducasse Oct. 8, 2009

Oct. 8, 2009

I suggest you to read the chapter on the Smalltalk model in the Squeak or pharo by example book the key is: when you look for a message you look in the CLASS of the receiver then its superclasses. So when you look for new sent to Array you should look in the Array class superclasses and you will see it contains Behavior before ProtoObject Stef PS: you can sent to the mailing-list just register to it. You do not need to have a google account.

[Pharo-project] Loading Gemstone Variable (Indexable) classes into Pharo via Monticello
by rkrock＠locksleycreeksoftware.com Oct. 8, 2009

Oct. 8, 2009

I have the following in Gemstone: FristClass which is a indexableSublass of Object. SecondClass which is a subclass of FirstClass. When I save this to Monticello and then load it into Pharo, the load fails on the 'recompile' because the SecondClass is not of type #variable. The load works when I modify the method MCClassDefinition>>createClass to use the superclass' type when the superclass type is #variable. --- current way ---- ... type: type; ... --- hacked way ---- .... type: ((superClass typeOfClass isSymbol not and: [superClass typeOfClass isVariable]) ifTrue: [superClass typeOfClass] ifFalse: [type]); .... With this I was sucessfully able to important the code into Pharo. I am able to go from Pharo to GemStone with no problems. Is there a general solution to this problem? It obviously will not occur very often. Regards, Reg

[Pharo-project] Linux so
by Schwab,Wilhelm K Oct. 7, 2009

Oct. 7, 2009

Hello all, Some dumb questions related to my ongoing migration away from Windows. Something that I have found useful is to write numerical analysis code (internally using templates, streams, etc.) in C++, and then compile them as extern "C" something like extern "C" _export void DoSomething(float * data, int rows, int columns) { // C++ specifics are legal herein; arguments // and return type must be legal for C - e.g. no references // and no classes; structs are ok. } On Windows with MinGW, the exporting of the function above seems to be almost magically easy. Do similar tricks work on Linux? On Linux, I intend to use gcc and Code::Blocks, unless somebody has a better idea. I bring this up in part because some things (tight loops) are best left to statically typed languages, C++ has a slight edge over Smalltalk on syntax for translating equations, I already have a lot of working C++ code, and I might be able to ease into getting GSL talking to Pharo before having to tackle the entire interface. I am hoping to add something to an evolving library, recompile, and perhaps after restarting Pharo have access to the new function(s) with fairly little hassle. Is that reasonable to ask? Any advice or warnings? Bill
