Re: [Pharo-project] Most wanted programming language:

by Guido Stepken

While deciders still reflect upon what programming language and framework to use, thinking about Java, .NET ... , Google and Apple have set new standards by pushing LLVM, V8, Webkit, node.js with a tremendous amount of money to perfection. Look at this example: http://monocle.inventivelabs.com.au/books/dubliners An epub reader object, good example for "ambient oriended programming". The reader behaves like an native app, independent on architecture, processor and os, touch, nontouch. Simply runs in every browser. And browser has javascript language bindings to all hardware, GPS, barometer, wifi, GSM, touch interface, mouse, cam .... if available. Porting PHARO onto Amber makes sense for me. Nothing else. COGVM, browser plugin, touch interface, portability discussion finished! IMHO the only chance for Smalltalk to come to new life. regards, Guido Stepken Am 10.01.2012 09:29 schrieb "Friedrich Dominicus" < frido(a)q-software-solutions.de>: > Dennis Schetinin <chaetal(a)gmail.com> writes: > > > Yes, we do: the (outer) world is getting worse and worse :) > No not really.

The problem i had stuck with is the inability to create a windowed context on Mac. For that i need to bind to either Carbon or Cocoa libs.. while i thought that i can just use basic functions. I were able to create an OpenGL context using coreGL (or something called Core) but i didn't managed to figure out what to do next. There seems to be lacking of windowing support on mac. So i could use this context as an offscreen context and it should work, but i'm not tried it yet. One of disappointment is that when i query the renderer used for given context, it reports an "Apple software renderer" , which not what i expected means that it is a software renderer, and not hardware acccelerated.. (or maybe it should be read as 'apple-software' renderer.. then there is more hope :) You can check the work if you load the package NBOpenGL-Mac.

[Pharo-project] SmallLint

by Simon Allier

Hi, I'm working on SmallLint. I have several ideas for improving SmallLint: The correction of some rules can be automated (eg Rule Unnecessary "= true" or Variable not reference) -> add transformation to these rules. Some rules such as Spelling rules (eg comments Method: Checks for spelling errors in method comments., 7088 problems) are not very interesting and could be removed (or treated differently?) Adding an indice of difficulty to correct the rule: - Level of automation for the correction of the rule (automatic, semi-automatic, â¦). - Scope of the rule (block, method, class â¦). Other costs could be - cost of applying (may be the rule requires to compute something else, or if a rule has 50000 hits, it generates an extra cost to analyze the results) - cost of NOT applying the rule (if it could detect a bug and we don' t apply it ...) Adding a manifest to manage/mark falses positive: - one manifest (a class) by package. - Manifest: exclusion of class/method of the package for rules or for all the rules. - Exclusion of rules for the package. One could also think on how to efficiently visualize the results of smallLint ... Simon Allier

I think we all noticed that :) With the exception that blocks return the value of the last statement, and methods return self by default. I would love if you could make an explicit local return from a block too.

Thank you Stef, Of course, any advice will be welcome. For the moment, the main difficulty to overcome is to contact with a group of smalltalkers in this area.
