To be precise, the symbols are also pointed to by the symbol table, but only by weak references.

Re: [Pharo-project] New User Experience Suggestion for 1.0

by Schwab,Wilhelm K

Interesting analogy given Pharo's roots in something widely (and proudly) considered a toy by its creators. However, a game is simply an entertainment medium, and it either works for you or it does not. A programming language hopefully gets a better look, and one with a free pdf book including a walk-through should be worth a noob's time. That said, a workspace full of examples is fine with me. But I continue to think that we should point people to PBE.

It is, but I think it's well worth considering what people think in their first couple of seconds of exposure to a new product - especially something like Smalltalk where people may well be looking at it only from idle curiosity. When I think how quickly and arbitrarily I can reject a game that someone's spent three years sweating blood over...

(Much faster, not quite as nice in details). Freetype fonts are available if needed, though. The pre-rendered fonts just replace the 80ties=looking Squeak fonts and provide a good enough selection for a development image.

Re: [Pharo-project] Dev09.12.1 does not look nice on Linux

by Henrik Johansen

The default fonts were changed, now Bitmap StrikeFonts are used instead of a TrueType font. Thus, the rendering method is completely different, and the use in StrikeFont rendering of some BitBlt methods revealed bugs in the alpha channel handling in said methods that previously went unnoticed. (Thus an updated VM/BitBlt plugin in required for them to render correctly).

Re: [Pharo-project] can I debug a primitive?

by Adrian Lienhard

That would be nice indeed. And you can do it if you simulate the VM, i.e., run the interpreter inside an image as Smalltalk code. To get the interpreter working may be challenging, though. I once had a working version and submitted some patches to Mantis. I don't think these were integrated, though. Also note that in the debugger you just see pointers and not objects, so even with the Smalltalk debugger it can get complicated to debug the VM.

Yes, I am newbie with low stuff like this. I have downloaded VMMaker and browse the class Interpreter to see the smalltalk (slang) code of the primitives I want to investigate that are primitiveStoreImageSegment and primitiveLoadImageSegment.....now, the question is, should I be able to put a self halt there and debug it? I tried but I did nothing. Is this possible ? I thought it was :( Thanks for the help. Mariano
