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

Polygons in woden
by Nicolas Lusa Nov. 17, 2014

Nov. 17, 2014

Hi everyone, I am working on some 3d representation and I am trying to draw 3D polygons with woden. I actually manage to make "the walls" but I still have to implement top and bottom parts which are not so simple since the shape can be really different from case to case. How I am actually doing it is with: WDGeometryBuilder adding vertices with addP: N: C: TC: messages and with addQuadI1: i2: i3: i4: Furthermore I have some issues with the shadows which actually don't appear. You can see a current polygon created with the code that I made in the attached image. (also notice the shadows are missing as well as the bottom and top part of the polygon). [cid:E6905B6F-F5CA-447D-A42D-BA1604AC7F5A@mobile.usilu.net] Now my question is: is there already something that makes those polygons or does anyone have any hint on how to make the top part with woden? Thannks in advance. Cheers, Nicolas

Re: [Pharo-users] How not to serve an AngularJs application from Pharo
by Stephan Eggermont Nov. 7, 2014

Kilon wrote >Really nice I now see the teapot stuff, for example this > >GET: 'demo/common/style.css' -> [ self styleCss ]; > >is really flexible meaning you can interpret http addresses and map them to pharo methods. This a really cool idea indeed, I see now why people are excited about teapot. Excuse my ignorance about web >development but html/css and js always scared me away :D I found it a very easy way to get some existing javascript app delivered fast from Pharo. It needs a lot of refactoring and cleaning up to become maintainable though. Separate classes for the angular components, and the canvas from Seaside to structure the html. A more difficult aspect is how to create the javascript. For (qc)magritte applications it looks like a builder should be able to generate form components and a json data binding. With GT it should even be possible to integrate javascript development directly in the pharo image. And it might be better to use React or Amber or SqueakJS Stephan

I've found this problem in Pharo 3 (seems to happen in Pharo 4 too): Do: 1. Fileout Seaside-Tests-Core 2. Remove Seaside-Test-Core 3. File in the file created in step 1 You will find: a. The structure of the package changes. b. Comments for WaContextTest are lost c. You get a bunch of errors in Transcript while filing in Any ideas? Thanks in advance.

I I have a C struct with a char* struct result { char* time } I define an ExternalStructure in FFI , with one field of type char* (note that the syntax char [5] is not accepted ! ). defineFields generates the accessors time and time: If I use time: â05:45â I get an error. How do I set a string value in an ExternalStructure ? Annick

Zoomable & Infinitely scrollable PasteupMorph
by Sean P. DeNigris Nov. 3, 2014

I need to create such a beast. What is my best bet to build on top of? I see the GT playground seems to have something like this for the Roassal previews... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Zoomable-Infinitely-scrollable-PasteupMorph-tp4778229… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
