Re: [Pharo-project] native boost is the best thing since COGVM

by Fernando Olivero

ok, i see your point. I will refactor back to Javier's approach. My rationale was to reify the Cairo library as it is, luckily all the other examples work. If i add the shared pool NBCairoTypes to the NBCairo then NativeBoost automatically associates the type? Because i've been putting directly "int". Would be nice to have a couple of examples of NB (whenever the time is enough for you guys, i know you are busy) thanks for the feedback, Fernando On Mon, Dec 12, 2011 at 5:05 PM, Igor Stasenko <siguctua(a)gmail.com> wrote: > CairoSamplePrograms>>rectangleAndText > does not works, because it uses a following method: > > NBCairo>>selectFont: aFamily slant: slant weight: aWeight on: aNBCairoContext > Â Â Â Â <primitive: #primitiveNativeCall module: #NativeBoostPlugin> > Â Â Â Â ^self call: #(void cairo_select_font_face (NBCairoContext aNBCairoContext, > Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â String aFamily, > > cairo_font_slant_t slant, > > cairo_font_weight_t aWeight) ) > > > and during code generation it barks that it unable to resolve > 'cairo_font_slant_t' Â type. > Because NBCairo class does not includes a corresponding shared pool > (NBCairoTypes). > > Also, Fernando, i don't like that you put everything into a single > class (NBCairo). > This is wrong, not object-oriented.

Re: [Pharo-project] native boost is the best thing since COGVM

CairoSamplePrograms>>rectangleAndText does not works, because it uses a following method: NBCairo>>selectFont: aFamily slant: slant weight: aWeight on: aNBCairoContext <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^self call: #(void cairo_select_font_face (NBCairoContext aNBCairoContext, String aFamily, cairo_font_slant_t slant, cairo_font_weight_t aWeight) ) and during code generation it barks that it unable to resolve 'cairo_font_slant_t' type. Because NBCairo class does not includes a corresponding shared pool (NBCairoTypes). Also, Fernando, i don't like that you put everything into a single class (NBCairo). This is wrong, not object-oriented. The original organization made by Javier was much more closer to my tastes. This approach to wrapping a library is too mechanical. It is much better to place calls at proper place(s) in proper classes, rather than putting everything into a single one. Which means that in this way you are at least 1 message send farther from real function call. But in your case its not even that.. NBCairoPattern>>status ^ self cairo patternStatusOf: self cairo ^ NBCairo default so , it is 2 extra message sends, instead of direct call to foreign function! -- Best regards, Igor Stasenko.

[Pharo-project] Scat - Public Release and announcement

by Bernat Romagosa

Hi list, Joan GÃ¼ell and I have been working on Scat -the Scratch port to Pharo- quite a lot recently. We wanted to push it to a point where we could release the first reasonably working version, which we've just managed today. Please take a look at the release announcement<http://code.google.com/p/scat/wiki/PublicRelease> (which should be read in a bit of a humorous tone), in which we explain what's up with the project and what future is left for it. For the tl;dr version, please read: - Many things are working, many aren't, but the state of the project allows us to move into more interesting stuff based on the graphic programming metaphor. - Scat is a time-consuming, brain-smashing, life sucking-project. - We no longer will be maintaining this massive unmaintainable code. - Suddenly: free time for other projects! Cheers everyone! -- Bernat Romagosa.

Re: [Pharo-project] native boost is the best thing since COGVM

A taste of what will be available: rendering the same GLabel (the gaucho equivalent to StringMorph), scaling the CairoCanvas. Pesudo Code: "create a label" label := GLabel on : 'hello Pango-Cairo'. "draw it on the canvas" label drawOn: canvas. "scale the canvas" canvas translateBy: aDelta ; scaleBy: aScale. "draw it on the canvas" label drawOn: canvas.
