funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

Package browser?
by Rob Vens June 28, 2013

June 28, 2013

I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. Should I still use categories? If I create a package in Monticello browser I am not able to add classes or anything (not as far as I could see). Just starting out using Pharo, so apologies if these questions are already answered elsewhere.

WebClient for 1.2.2?
by Andy Burnett May 7, 2011

May 7, 2011

Hello list, Is there a working version of the WebClient for 1.2.1? I tried loading the webclient-pharo package from squeaksource, but didn't get anywhere. Before, I dug further I wonder if someone can point me in the right direction.

We would like to improve the system and clean it. Unfortunately, sometimes there is no other way than loosing backward compatibility. What do you prefer? Pharo choose a better system. If you/companies do not even collaborate with updating your code (don't say even fixing bugs or submitting code) ...then don't expect anything from Pharo. Pharo is open-source, free and it is build in the free time. And I think Pharo is not the only one....out there most of the languages change a lot between versions, Python, blah.

An small "interactive art" project in Pharo, from a newbie
by Offray Vladimir Luna CÃ¡rdenas May 2, 2011

May 2, 2011

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, First thanks for Pharo. Is a really nice clean innovative environment I have just pointed it to some java teachers/users and they like the overall look and feel. Now some small context: I had taken a short seminar on interactive art. We have used vvvv[1] to make some small experiments and the idea was to use arduino with it, but being it windows only I though in exploring something easy to use and then I found Physical Etoys from Richo's team. [1] http://vvvv.org [2] http://tecnodacta.com.ar/gira/projects/physical-etoys/arduino/ We don't make any further work arduino, but the essence of the seminar was overlapping meanings to create new meanings. So my idea is to make some images appear and vanish slowly after a while and also put some microblogging flux of information. I started with etoys, but after seeing that the tile language will not give me the proper expressiveness to create this project I have "go down" to Smalltalk using Pharo. I'm a total newbie but I have found some ways to load images (using SketchMorph). Now I want to make them vanish slowly and also load the microblogging stream (from Twitter and Identica, containing an special hashtag). This is supposed to be a small week project but is taking longer. I have asked in the Squeakland and SqueakNewbies mailing list and I got an answer from the etoys perspective but is not what I need so any pointer to the proper documentation will be appreciated (hopefully on Sunday :-P) Meanwhile I will keep reading the Pharo by Example book trying to get the spirit of development process and waiting for your kindly help :), to hopefully get some prototype on Monday.

Refactoring and with: [] indention
by Scott Gibson April 30, 2011

April 30, 2011

When I refactor, or format the code, there seems to be too much indention where "with: []" is used. For example: renderHeaderOn: html (html div) id: 'header'; with: [ self renderLoginOn: html. self renderLogoOn: html. self renderMenuOn: html ] Is this how it is supposed to be? Is there a way to reduce the indention by one level if so? Thanks! Scott Gibson

Pharo 1.2.1 and ProfStef
by Markus Schlager April 29, 2011

April 29, 2011

Hi all, I'm teaching smalltalk to my pupils using a ProfStef-tutorial (http://www.lsh-marquartstein.de/schule/unterricht/faecher/informatik/unterr…) Currently we're using pharo 1.1. In pharo 1.2 ProfStefBrowser obviously got replaced by another HelpBrowser. (What you get with Help->ProfStef Tutorials). I'm missing two things: - syntax-highlighting: Is there any way, I can activate this easily? - navigation-buttons and page-counter (at the moment, my tutorial has about 60 pages): any chance to get these back?

DBXTalk (SqueakDBX) goes to Pharo 1.3

Hi. This is just to let you know that SqueakDBX (soon DBXTalk) has 100% green tests in Pharo 1.3 without chaning one single line of code. In addition, half of the team is using Pharo 1.3 and the other one 1.2. We updated ConfigurationOfSquealDBX >> #stable Cheers -- Mariano http://marianopeck.wordpress.com

Yes, using the old version of Pharo that you used when you implemented them. Like MacOS 9 programs run on MacOS 9. If you want to run your MacOS 9 Program on MacOSX, there is for a time an emulator, and for a time some source compatibility. But in the end, the only option is to port. There is no magic. You can select between -> Inventing the Future -> Be compatible to the Past at any cost. If what you have in the Past is valuable, selecting the second option makes sense. (IBM, Microsoft). If not, then it's idiotic. We will improve this a bit in the future, but this is research, so no promises.

Hi. IMPORTANT: This is not the final 1.3 release, it just one simple snapshot and one point. We all want a rock-solid Pharo 1.3 release, but that doesn't happens automagically. We all need to start using and testing the image before they are release. It is for the better of all of us. The more we test the more stable will be the release. So...we need your help. What you can do? 1) test test test test test. Use it. Take this image and use it for your regular work. 2) report bugs: http://www.pharo-project.org/community/issue-tracking 3) propose fixes: http://code.google.com/p/pharo/wiki/HowToContribute 4) Fix errors/failures tests 5) Load your OWN packages and projects now. Don't wait until Pharo1.3 is released and then ask "uuhh what happened to XXX? you removed? ohhh but I use it". 6) Do you maintain Metacello configurations? ok, if you test your project and works correctly in Pharo 1.3, please update (or create if you don't yet have it) the #stable, 7) Do you maintain packages included in Pharo? please check we are using the correct versions 8) I would like to see people testing AidaWeb, Magma, Fuel, Moose, DBXTalk, Seaside and all its friends, Zinc, FileSystem, etc, etc, etc. Pharo-1.3-13173 should work with Interpreter VM and with Cog. For Cog I recommend to download the last one from Eliot's page: http://www.mirandabanda.org/files/Cog/VM/ Two little warnings: - The Transcript is read only....and it will probably be roll backed to the previous one - if text editing looks weird....it is Lukas's fault ;) http://www.youtube.com/watch?v=fTMX1f8Lu5w Ok, the image is here: https://gforge.inria.fr/frs/download.php/28517/Pharo-1.3-13173.zip<https://gforge.inria.fr/frs/download.php/28517/Pharo-1.3-13173.zip> And it was build by Hudson: https://pharo-ic.lille.inria.fr/hudson/view/Pharo/job/Pharo%201.3/111/ Best regards, -- Mariano http://marianopeck.wordpress.com

This is impossible and, in the end, not a good idea. We can not be compatible forever, was this would mean that we can not improve anything. e.g. imagine someone would fix the VM to be better. (e.g. a modern object format). Do you really request to then *not* do this change because this VM could not run old images? (and new images would not run on old VMs?). Do you want to have a Future or be compatible to the Past? Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

My 2 cents on this topic: user interface consistency cannot be underestimated. I called these 'leds' unit-test icons because thats what they are (in my mind and I guess also for a lot of other people). So using them for anything else is not a good idea at all. Alex' proposal seems (to me) a much better idea. On 23 Apr 2011, at 13:05, Alexandre Bergel wrote: > I agree with you. The browser is not yet a replacement for manual editing.
