Aconcagua Documentation
by Sean P. DeNigris March 19, 2015

March 19, 2015

Is there anything besides http://stephane.ducasse.free.fr/Teaching/CoursAnnecy/0506-M1-COO/aconcagua-… ? There are not many class comments and the tests were a bit overwhelming for me... Specifically I'm searching for anything built-in to present measures in the "most tidy" representation e.g. "125 dollars" instead of "12500 cents", "10 cups" instead of "480 teaspoons", etc. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Aconcagua-Documentation-tp4759781.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Changes file size
by Esteban A. Maringolo Feb. 13, 2015

Feb. 13, 2015

I know we're on our way to get rid of changes, but meanwhile after installing my Metacello config I end up with an image of 40megs and a changes file of 140 megs!!! It doesn't load anything too esoteric: Glorp, Magritte, Seaside, Postgres, NeoCSV and my own packages. I can run PharoChangesCondenser condense, but it takes forever! (I started it 20 minutes ago and it's still running). Is there a way I can improve this situation? Esteban A. Maringolo

Installing GToolkit
by Evan Donahue Feb. 3, 2015

Feb. 3, 2015

Hello, I am trying to check out GTPlaygroundl, but I can't seem to get it working and was wondering if anyone had any idea what I might be overlooking. I download a new image with curl get.pharo.org | bash I run, from http://www.humane-assessment.com/blog/installing-gtoolkit Gofer new smalltalkhubUser: 'Moose' project: 'GToolkit'; configuration; loadDevelopment. #GTImageSetupCommandLineHandler asClass new activate It loads for a while and then the image closes. When I open it again the background is white and my settings have been wiped. The playground does appear, but it doesn't seem to work properly (there seems to be no way to advance the miller columns). Am I looking at the wrong installation information? Thanks, Evan

How do I save contents of Workspace into a collection?
by Frank Church Jan. 31, 2015

Jan. 31, 2015

Hi guys, My images are gathering a number of Workspaces whose contents I don't want to delete. I want to create a collection of Workspace contents along this defintion: Description Date Category Content (the actual text in the Workspace). In the final version I would like to be able to select a workspace and simply click a button or a menu item and get a dialog where I can enter the Description, Category and Date with the Workspace contents automatically captured into a text box. Copying and pasting the contents would be okay to start with. Filing it out would be another aspect later. What kind of array would best suited to the task? There is quite a number of them depicted here: http://www.jmcsweeney.co.uk/computing/m206/collections_intro.php What could be the best way to go about it? For those who are curious I am experimenting with the original ideas of Smalltalk where a computer user would do everything in Smalltalk workspace/desktop. I am intrigued by the possibility and somehow it seems eminently doable. -- Frank Church ======================= http://devblog.brahmancreations.com

if Pharo is key for you
by StÃ©phane Ducasse Jan. 18, 2015

Jan. 18, 2015

Hi guys if Pharo is key for you then you should ask yourself what you did for Pharo recently. Writing code, writing documentation helping closing bug entries, participating to the association, to the consortium... Pharo is not happening from spontaneous generation. Stef

[ANN] Spec documentation in PFTE book finished
by Johan Fabry Jan. 2, 2015

Jan. 2, 2015

Hi all, I am happy to announce that Ben and I finished the documentation of Spec for the Pharo For The Enterprise book. This documentation is up-to-date with the latest version of Spec, and is focused towards people wanting to use it and even extend it (in contrast to the academic papers which are â¦ academic ;-) ). I hope that this text will help all the people that are building UIs in Pharo, and it will clear up any doubts that they may have. The chapter is available in source form from the GitHub project of the PFTE book: https://github.com/SquareBracketAssociates/PharoForTheEnterprise-english The easiest way to read the chapter is from the continuous integration server, which produces a html file of the chapter here: https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSucces… (The same server also produces pdf and markdown files, but there are some strange artifacts there, currently. I guess this will be cleared up in the future) We tried our best to make it understandable and complete, but if you have any doubts or comments please do not hesitate to let us know !! Ben prefers Github apparently, but if you are oldskool like me you can also send a mail (privately or to the mailing list). Now it's time to build some cool user interfaces! :-) ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

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.
