FileLibraries (files as methods)
by Esteban A. Maringolo March 17, 2014

March 17, 2014

Well... I accidentally clicked in the InfoVis method #jitJs of InfoVisDevelopmentLibrary and it hung the whole image/vm (latest pharo 2 build). Without any chance of halting it. I don't know if it is something related with the parsing/syntax highlighting, but there should be a way to flag such methods and treat them differently. Regards! Esteban A. Maringolo

Pharo 3.0 image shrink
by Hilaire Fernandes March 17, 2014

March 17, 2014

Hi, I want to look at shrinking Pharo 3.0 image for iStoa. In that context I don't need anymore the developer tools In Pharo 1.4 I experimented with unload-packages-and see-of-it-broke-or not-the-image. Do we have a better way to do it with 3.0? Which package to remove and how? I remember the other of unloading matter. I just tried UnReloader package. But "UnReloader new unload" turn my Pharo display all white. However, it looks like it is still working. Is it normal? Thanks Hilaire -- Dr. Geo http://drgeo.eu

Metacello changes in Pharo 3?
by MartinW March 16, 2014

March 16, 2014

Hi, it seems Metacallo changed in Pharo 3 compared to Pharo 2. First thing i noticed was that a Configuration does no longer seem to be supposed to subclass from Object but from ConfigurationOf? Are there other changes? Where can i learn about them? Is there an official documentation that describes the Metacello Version in Pharo 3? Best regards, Martin. -- View this message in context: http://forum.world.st/Metacello-changes-in-Pharo-3-tp4749011.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

RRDTool - Graphs
by phil＠highoctane.be March 14, 2014

March 14, 2014

I wanted to know if someone has a package to deal with RRD tool files and graphs directly from Pharo. RRDTool is: http://oss.oetiker.ch/rrdtool/ I'd like to to use these things in a Seaside application. TIA Phil

Am not sure if that is a good idea
by Friedrich Dominicus March 12, 2014

March 12, 2014

anyway. Has anyone considered adding filtering to the Debugger (in my case the Glamorous Debugger) in a way that not all instance variables values are shown in the value pane? Well a kind of watch as in other debuggers. You just can "ask" to watch e.g field firstName but not lastName or something like that. Even if I try to keep the information down some classes still do have a lot of elements (think of articles, which usually have at least some kind of id, a description, a price tag, but also some other information (be it internal or extenal for the programm)

Nice job, Ricky! Playground is great for showing off CodeCity examples. I found the browse source menu on an example. I had expected to have a source view tab for that. Stephan

CodeCity
by Richard Wettel March 11, 2014

March 11, 2014

Dear all After the short preview at the last Moose Dojo, I am happy to let you know that the first version of the brand new CodeCity is out. CodeCity is a 3D visualization engineased on a city metaphor, which enables us to depict software systems as cities. If you want to know more about this approach, have a look here: http://www.inf.usi.ch/phd/wettel/codecity.html I have now implemented the basic functionality of CodeCity in Pharo and integrated it with Moose. Here is a code city of ArgoUML in the new CodeCity: [image: Inline image 1] To install CodeCity, you need to run this code in a Moose image (setting Moose as a prerequisite is on my TODO list): Gofer new smalltalkhubUser: 'RichardWettel' project: 'CodeCity'; configuration; load. (Smalltalk at: #ConfigurationOfCodeCity) loadDevelopment You can also get the latest successful build from: http://ci.inria.fr/moose/job/codecity/lastSuccessfulBuild/artifact/codecity… The new CodeCity does not provide a configuration UI, but it relies on scripting. A script to obtain a city visualization of a Moose model is shown here: [image: Inline image 4] A good way to get familiar with the scripting API of CodeCity are the examples. You can open CCBuilder in the new workspace (Playground) and you can browse the examples (the "e.g." tab). [image: Inline image 2] While CodeCity was initially aimed at software systems only, there is nothing that stops us to use it at visualizing any kind of data! One example was the visualization of the data taken from a database (population, city, countries, continents) presented at the Moose Dojo. I'm sure Doru will be pleased to show you more of that. In conclusion, I hope you'll enjoy playing/working with CodeCity as much as I have been enjoying re-implementing it in the last few months. Playing with CodeCity integrated in the Moose workflows is pure fun. But don' take my word for it, just give it a try! Cheers Ricky
