Are you sure C++ compilation is the best way ? There are a lot of flaws: Smalltalk needs to be restrictive or will be compiled to very slow code, you will loose debugging features, etc. I would try to integrate Pharo the same way lua is integrated in engines like Source2 from valve: you run your

Re: [Pharo-users] Compiling Pharo to C++

Ok. Then I guess you can do something like Slang, which is used for the VM. Slang is a restrictive Smalltalk compiling to C. The slang compiler parses the code using the Smalltalk Compiler parser, then translate the Smalltalk AST to its own AST, do some manipulation based on pragmas available in

Re: [Pharo-users] stupid spur question

Hello, Both classes (SmallFloat64 and BoxedFloat64) are present on 32 bits and 64 bits by default right now. The code base is common between 32 and 64 bit images. It is possible to run a 32 bit image without the class SmallFloat64, but it is not the default behavior. There are no instances of

sourceCode is the best way to do it. It answers the original sources if available, and the decompiled sources if not available. 2016-03-10 11:22 GMT+01:00 Cyril Ferlicot : > Hi, > > Do you really need to decompile the method? A CompiledMethod know his > source code. > >

Alternatively, I do that using a SDL window. This way, the production game can be launched using SDL and pharo headless, and not have the overhead of the morphic rendering loop. 2016-03-13 15:22 GMT+01:00 Henrik Nergaard : > http://ws.stfx.eu/1RCNV18R5J7E > > Best

Re: [Pharo-users] What frameworks/libraries are available for creating programming languages with Pharo

I think in addition of the parser/compilation chain, a language is about having a good IDE. The Pharo IDE depends more and more on the AST and not on the source code, so if your new language uses an AST polymorphic with the Smalltalk AST I guess you can have IDE tools for free (at least partly).

Hello Ben, The limit you see for instance variables is due to: - Class format encoding (Memory manager dependent) - Bytecode set encoding (Bytecode set dependent) The 255 inst var limit is enforced both by: - the V3 Memory manager - the SqueakV3PlusClosures bytecode set. Now we have Spur

Re: [Pharo-users] Pharo5 download for linux - interpreter cannot read image file

Thanks for reporting the problem. The error means the VM is incompatible with the image. There was a change of image format in Pharo 5, so the package has likely an old VM while the image has the new format, or the new VM while the image has the old format. Someone will look into that problem in
