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.

Backward compatibility [WAS] Re: [ANN] PharoDev-1.3-13173

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. Cheers, Offray -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJNs4TsAAoJEGiex2828ICwbfMIALJlY2LqVCYA0s1wJReveeL5 SWNpnoGEnbwvnZIdn9x6IKkXnEBcd6XDOL09aZtcnSpOIABqsYD65vw5+O9FINnI 7WRQKmYag+0dlvifrJY5/eAlMuJ++5c90sqB2VuPxruD4Npkwcui3aVZUHLFHSIl Y+PdO8S2cw6+dObS4lLIy3YmhdNp14ZIsWDFZdKMpofaT1dsDt1gEXzDUz/HaPKA Ft0lFUsT6jHLUNE9Pd2O9XcjUeOwwZDHNyvm0Ij/wcJ+HEH9v5OsuXa1C0ayiQb6 0gQJhT8OjYgwRh1GfNKL+nCczUs/uetgZ4z0twY8GT6eCFrJbva516eoJ0UVutk= =Y2AY -----END PGP SIGNATURE-----

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
by Mariano Martinez Peck April 29, 2011

April 29, 2011

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
