The _whole_ Pharo system depicted:
by Alexandre Bergel Dec. 5, 2014

Dec. 5, 2014

Hi! I played a bit this morning. This is the whole Pharo: A detail of this picture: There are over 100 000 methods and over 65 000 edges. Each circle is a method. Color of the method indicates its class. Edges are self-call between methods (e.g., a method "foo ^ self barâ will creates a link between #foo and #bar. The very short script to produce it and a large version of the pictures are available on: https://www.facebook.com/ObjectProfile/posts/742756179144315 Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Umlauts in ZnUrl
by Udo Schneider Dec. 4, 2014

Dec. 4, 2014

All, What's the expected behavior with non-ASCII characters in URLs. Let's say I want to access a file named "Ã¤Ã¶Ã¼.txt" - My assumption was that Zinc takes care of the UTF-8 -> 7bit (ASCII) -> Escape encoding. But there is either something I don't understand or some manual steps I'm missing. The "straightforward" way doesn't work: 'http://myhost/path/with/umlaut/Ã¤Ã¶Ã¼.txt' asUrl. "ZnCharacterEncodingError: ASCII character expected" Although the actual encoding seems to be able to handle it (ignoring the escapes slashes for the moment: 'http://myhost/path/with/umlaut/Ã¤Ã¶Ã¼.txt' urlEncoded. "'http%3A%2F%2Fmyhost%2Fpath%2Fwith%2Fumlaut%2F%C3%A4%C3%B6%C3%BC.txt'" Creating a URL from already escaped characters works as well: 'http://myhost/path/with/umlaut/%C3%A4%C3%B6%C3%BC.txt' asUrl. "http://myhost/path/with/umlaut/%C3%A4%C3%B6%C3%BC.txt" As does the decoding of such an URL: 'http://myhost/path/with/umlaut/%C3%A4%C3%B6%C3%BC.txt' urlDecoded. "'http://myhost/path/with/umlaut/Ã¤Ã¶Ã¼.txt'" At them moment I'm manually encoding UTF-8 characters in paths segments before trying to build the URL. But is this the correct way? Best Regards, Udo

HelpSystem / HelpBrowser features
by HernÃ¡n Morales Durand Dec. 3, 2014

Dec. 3, 2014

Hi all, I am currently using the HelpSystem to provide help for my application. I think the PluggableTextMorph used in the HelpBrowser (currently) does not support attaching screenshots or videos. I haven't see how to include a table neither. Does anyone has experimented in such direction? Any recommendations or hints? HernÃ¡n

MVC/ MVP / DCI Patterns..
by S Krish Nov. 29, 2014

Nov. 29, 2014

In the context of spec / UI / enterprise solutions, I have been mulling over this for some time especially when I play with FXML. To put it in context, I find FXML intriguing and nice. XML metadata that stays completely outside the code and makes it uber flexible to weave in UI to a enterprise solution post facto. The thought trail I have is: Typical Pattern: Model links to Controller that links to a: Customer View ( singleton ? ) Controller links to: Validators / Delegates.. et als.. Model links to in Memory Cache registry { that links to: Persistence Module.. I do not bother about this for now..} In FXML I see nice convention over configuration approach: * XML format.. understood by people/ more importantly editors at large.. * Controller is injectable * all method calls onAction/ events are simple viz #handleSubmitButtonAction or the ilk.. that will thereby call the controller instance methods.. * fxml can also invoke simple ( or complex) javascript action viz: jsSubmitAction( event) Would Spec see that kind of approach.. feasible for extensibility Food for thought more as rethink on fundamental patterns: a) Should view have knowledge explicitly of its Controller.. Or Controller while creating the view injects its instance.. only.. b) Should we push Controller to be a Presenter.. as the case tends to be. And then let Controller be the gateway to all other parts.. as listed above.. c) View actions & callbacks & validators are separated and dealt with a view "controller" , but the gateway to all other parts is handled by a real "observer controller" ... There has to be reliable: * bidirectional update from view -> model ( in cache ) * proper modular segregation of all parts of a standard enterprise app. to enable common and known functions of each part, flexible, scalable but importantly easily maintainable.. in future by developer other than the author.. * Scriptability is one of the desired capabilities with the shrink wrapped app to be extended

libevent binding for haro ?
by Alain Rastoul Nov. 28, 2014

Nov. 28, 2014

Do someone knows about a libevent binding for Pharo , or made experiments with Pharo and this library ? After some experiment with the standard socket IO handling, I have the feeling that it cannot scale on unix and neither on windows ... TIA Regards Alain

ViDI Error: glx not supported
by Rafael Luque Nov. 27, 2014

Nov. 27, 2014

Hi, I installed ViDI on Pharo 4 following the project instructions detailed in its GitHub page: Gofer new smalltalkhubUser: 'YuriyTymchuk' project: 'Configuration'; configurationOf: 'Vidi'; load. #ConfigurationOfVidi asClass loadStable When I launch the ViDI option I get the error: "Error: glx not supported". I'm using Gentoo Linux with NVidia Optimus graphic card, so I use bumblebee to switch to NVidia and launched pharo using optirun command like this: $ optirun pharo-ui my-image I get glxspheres64 running successfully using the same procedure. How can I activate GLX support inside the Pharo image? I noted the option System > Settings > FFI > "Path to OpenGL library (on linux)" however I don't see (or I don't know) how to set this value. Thank you.
