[Pharo-dev] NBCodeGenRecursion:NativeBoostWin32>>#bootstrapAllocate:into:

by Guy Hylton

My NativeBoost journey has reached the point where I would like to use some of the NBExternalStructure extensions available in development version 2.2 but I can't get past a NBCodeGenRecursion error which occurs when I run the NB tests. I put some halts into the NB code and thought that I had cracked it because NativeBoostWin32>>basicAllocate: calls NativeBoost>>callGateFunctionAddress which calls NativeBoostWin32>>basicAlloate:, but then I realised that the same thing was happening in the stable version I was using ... so I guess that I am looking in the wrong area? Were should I look next?

Address is just a location in memory, where the value(s) (could be) stored. For any function which takes a pointer, you can pass an instance of ByteArray, or instance of NBExternalAddress to it. In first case, a pointer to first byte of bytearray will be passed to function, in second one , the value of address. So, you either allocate buffer in object memory, or external memory.. fill it with whatever it needs and pass to function.

Fwd: [Pharo-users] Tudor Girba joins Pharo Board

by Tudor Girba

I forgot again to push the reply all button. Doru ---------- Forwarded message ---------- From: Tudor Girba <tudor(a)tudorgirba.com> Date: Wed, Jul 3, 2013 at 9:59 AM Subject: Re: [Pharo-users] [Pharo-dev] Tudor Girba joins Pharo Board To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> Hi everyone, Thanks for the wishes. Just a note: I do not see getting in the board as a prize, but as a work to do. And there is some work left :) One of the points that I will stress everyone with is the marketing of Pharo. Marketing, like any other meaningful thing, requires design. Design requires feedback. And feedback requires time. That is why we have to start with this endeavor sooner rather than later. The other thing about marketing is that it can actually be meaningful, but this happens only when we live what we sell. Pharo does offer a fantastic opportunity because when people talk about it, their eyes blink. This reveals both value and values that are packaged deep in Pharo. We just have to capitalize on that, and I want to start by making explicit what makes Pharo unique and valuable. Everyone thinks of various things, but we do not yet have a concerted message. This message, and I will aim at one single message, has to transpire in everything we do: from the way we design the code, to the concepts we adopt in the language, to the frameworks we build on top, and to the developer and user experience. This is exciting, but it requires team effort. This is where you come in. We want your energy outside of pure coding. More concrete proposals will come in the near future, but until then, feel free to chip in your ideas.

NativeBoost with no access to sources

Is there something against that ? It seems as if NB is used to check file existence / isReadable, then, upon startup, the vm is unable to open the changes file and all NB calls becomes incorrect.

Re: [Pharo-dev] Text Encoding questions

Le 03/07/2013 09:55, Camillo Bruni a Ã©crit : > AFAIK that might depend on the font ;). Oh, that sounds about right. > Do you have the same font for everything? In the settings, yes. Oh, finally, no. The Bitmap DejaVu Sans used by default was the culprit, the rest of the fonts were set automagically to DejaVu Sans (without the Bitmap). It went correct with selecting DejaVu Sans Regular 9 for the Default font (instead of Bitmap DejaVu Sans Regular 9). > I remember having problems displaying some strange characters in methods, whereas they would show up fine in the inspectors. > If you have a reproducible use case can you open a bug report with a nice description?
