Re: [Pharo-users] [Seaside] Seaside can not be used with Pharo 60261

by Johan Brichau

Sure. Christophe Demarey has asked me if he can publish his changes to fix the config for pharo 6. I will upload them as soon as I receive them Johan > On 17 Oct 2016, at 21:04, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: > > this is a question more appropriate for Seaside list :) > >> On 17 Oct 2016, at 20:07, Pierre CHANSON <chans.pierre(a)gmail.com> wrote: >> >> In #SmalltalkImage>>metacelloPlatformAttributes, #'pharo5.x' #'pharo5.0.xâ have been removed and Seaside does not have configuration for pharo6. >> >> Is there a plan to update the configuration of Seaside ? >> >> Thanks ! >> >> Pierre and Norbert > > _______________________________________________ > seaside mailing list > seaside(a)lists.squeakfoundation.org > http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside

Re: [Pharo-users] CodeGenerator, your opinions?

by Dimitris Chloupis

There is the CCodeGenerator , which is basically Slang, Smalltalk that is turned into basic C. I would like to expand it to generate C++ at some point for converting pharo code to C++ code that I will be able to add to Unreal. Though its a very low priority project for me. http://smalltalkhub.com/#!/~PavelKrivanek/CCodeGenerator Personally I am against generalized solutions because they tend to be bad for specialized cases , on the other hand I welcome any code that I can use as inspiration for my own code generator.

Re: [Pharo-users] Cog VM on Raspberry Pi ?

by ClÃ©ment Bera

The VM you use is the fastest one available. It's slower mostly due to non Smalltalk concerns (processor architecture, energy consumption, frequency, overall hardware). There is an abstraction over the back-ends in the JIT and it could be that overall the JIT is a little bit more optimised for intel than for ARM. But I would guess that's a 20% difference at most, if difference there is.

Re: [Pharo-users] CodeGenerator, your opinions?

by Julien Delplanque

Hello, A generator for the visitor design pattern: - Generate methods in visited objects: VisitedObject>>#accept: (with the selector name configurable) - Generate empty methods (or methods with a "self subclassResponsability" if an abstract visitor is generated) called in #accept: methods of VisitedObjects in the Visitor i.e Visitor>>#acceptVisitedObject: (with the selector name configurable again). Each time this design pattern has to be used, it is annoying to write by hand all these methods.

CodeGenerator, your opinions?

by HernÃ¡n Morales Durand

Hi guys, I am writing a code generator, doing a few iterations right now. I want your opinion, which most useful thing would you like to be generated automatically? It could be a pattern, an idiom, another language... For example my own wish (roadmap) list: - A "settings framework" settings class generator. - A state machine generator (based in the excellent paper of Trevor P. Hopkins) - A Spec UI generator. Let me know your thoughts. Cheers, HernÃ¡n

[ANN] ZÃ¼rich Smalltalk Meetup Nov 8th, 2016

by jtuchel＠objektfabrik.de

There are great news about the upcoming Smalltalkerâs Meetup in ZÃ¼rich. Weâve found a conference room for the evening and will start off with a âshow us your projectâ session in a room with a big screen and start the social part after your input at a nice Australian Steakhouse. The best thing is: we already have a first session: Michal is going to show his new Gemstone-based persistence framework for Pharo. It can be used to develop in Pharo and keep your objects stored in Gemstone. We need your input This new setup with a meeting room adds more value to all of us: we can now not only talk about each othersâ epxeriences and porjects, but see what theyâre up to and what they found. So to make this event an even better one than before, we need people whoâd like to share their ideas, their latest work on some hobby or professional project. Thereâs no need for a full-fledged sales pitch with fog and visual effects and such, just bring your laptop and show us what you do! The room is reserved for ca. 1 hour, so we can have, say, 2-3 presentations before we leave for beer and steaks. So if you have something interesting to show or would like to find people to join on some early project youâre starting/planning, give us a chance to learn about it. If youâve built some interesting tool or use Smalltalk for something very special to you, let us know and share your fascination and ideas. Weâll sure appreciate that! But if you spontaneously decide you want to show something or start some discussion, feel free to do so. You just need to be prepared that we might have to leave the room before itâs your turn. Timeslots are limited. It would be good if youâd pre-announce your demo to me for two reasons: first, we can see if we need to rent tho room for a little longer, but even better, your topic might attract even more people so I can post your topic and make sure people get the message. So where and when? Weâll meet at 7pm on Nov 8th, 2016 at Alpha Sprachwelt AG <http://alphasprachwelt.ch/kontakt.html> Stadelhoferstrasse 10 8001 ZÃ¼rich Around 8-8:30 pm weâll walk over to the Outback Lodge where weâve reserved a table. With Steaks and Drinks we can discuss ideas, talk about the good old times or do some spontaneous hacking. For directions to the Lodge visit http://www.outback-lodge.ch/index.php/stadelhofen How to register? How much is it? This is a meetup of friends, so itâs free to come, we look forward to meeting you and keeping in touch. You pay your meal and drinks, but the rest is free. We ask you to register on our Doodle page at http://doodle.com/poll/c9c7tatwqppyhkhq Please also indicate in a comment to your registration if you want to give a short presentation. See you soon in ZÃ¼rich!

Cog VM on Raspberry Pi ?

by Sven Van Caekenberghe

Hi, Does a (faster) Cog VM for the Raspberry Pi actually exist ? I tried comparing the latest OpenSmalltalk VM with some older ones, only to find that they are all equally fast (slow actually): pi@raspberrypi ~/Pharo $ ./pharo -nodisplay Pharo.image printVersion [version] 5.0 #50581 "http://files.pharo.org/vm/pharoS/raspbian/latest.zip" pi@raspberrypi ~/Pharo $ ./pharo -nodisplay Pharo.image eval '1 tinyBenchmarks' '167429692 bytecodes/sec; 11160247 sends/sec' "http://www.mirandabanda.org/files/Cog/VM/VM.r3427/cogspurlinuxhtARM-15.33.3…" pi@raspberrypi ~/Pharo $ ./products/phcogspurlinuxhtRPi/pharo -nodisplay Pharo.image eval '1 tinyBenchmarks' '166992824 bytecodes/sec; 11337746 sends/sec' "https://bintray.com/opensmalltalk/vm/download_file?file_path=cog_linux32ARM…" pi@raspberrypi ~/Pharo $ ./products/phcogspurlinuxhtRPi/pharo -nodisplay Pharo.image eval '1 tinyBenchmarks' '166992824 bytecodes/sec; 11337746 sends/sec' That is no significant difference on a RPi 3, at all. Is this normal ? Am I missing something ? Thx, Sven PS: Just for reference, my Mac Book Pro is 10 times faster 1 tinyBenchmarks "'1323852617 bytecodes/sec; 174185794 sends/sec'"

Re: [Pharo-users] Garage sqlite on pharo > 5

by phil＠highoctane.be

Why declare that as dead? It is there and is okay to use. People can update it if needed. Why say this? That's not constructive, man. We need DB access. Pharo without DB access is going nowhere in the industry. Just had a pairing session w/ Doru and guess what? The data I need for Moose/Roassal usage is in a database. -_O Phil On Mon, Oct 17, 2016 at 7:29 PM, stepharo <stepharo(a)free.fr> wrote: > Guillermo created Garage because the consortium asked and payed him to do > and I think that he did it well.
