Re: [Pharo-project] [Moose-dev] Performance of text presentation in Glamour

Hmm, I would like to know the answer as well. As far as I can tell, the problem is given by transforming the String into Text, and this is done by PluggableTextMorph. Does anyone have a clue on how to proceed when we want to display a large amount of text in a Morph?

[Pharo-project] how to find the memory size of an object graph
by Tudor Girba July 23, 2012

July 23, 2012

Hi, I have some problems with memory consumption in a Moose model. However, I do not quite know where the memory is spent. To solve this, I would need to know the amount of space occupied by the objects (and all the referenced objects subgraphs). I found Object>>sizeInMemory, but this only shows the size of the current object. What I would need is a graph traversal that does not break on cyclic graphs, and that accumulates the size of the objects. I thought of using Fuel for this. I tried to follow the instructions from here: http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.8/Documentation/… and work with the debug facilities: (ConfigurationOfFuel project version: '1.8') load: #(FuelDebug). For small examples, it seems to work fine: FLAnalyzer newDefault setDebug; analysisFor: #((1) (2) (3) (4)) However, for larger examples, the process takes forever. Is there another way of approaching this problem? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

[Pharo-project] shortcut to copy inside class comment does not work

Hi guys. If with Nautilus you click in the class comments, and try to copy a piece of text from the comment with cmd+c it does not work! But it works if I do it from the menu. So I guess it is a problem with the shortcuts... cheers, -- Mariano http://marianopeck.wordpress.com

[Pharo-project] Customizing the Caret of a PluggableTextMorph
by Sean P. DeNigris July 22, 2012

July 22, 2012

For VimPharo, I want to have a different cursor depending on whether a tool is in insert or normal mode. I tried a handful of ways, but they all failed or worked partially/inconsistently. Here's some of them: * add the state to the paragraph, but the entire paragraph gets replaced during the life of the tool, so the state gets lost * add the state to the editor, but the situation is the same * add the state to PluggableTextMorph, override and access it from TextMorphForEditView>>updateFromParagraph. This was an extreme PITA and got me very acquainted with the emergency evaluator. It "worked", but only after using the arrows a bit. Does anyone have any idea where I might hook in? <rant>I find the whole text system very confusing. What the heck does a paragraph know about insertion points?? A view has one paragraph object, even if there are several paragraphs (as understood by the rest of humanity as a block of text with breaks between the adjoining ones. Editors and Paragraphs are thrown out and replaced on a whim.

[Pharo-project] Brain storming request: Semantic zooming for Roassal
by Alexandre Bergel July 22, 2012

July 22, 2012

Hi! I've just found this video: http://cel.inf.usi.ch/index.php?action=gallery I am not sure I really want to program a tetris that way, but the tool they have is interesting. It intensively use zooming in and out. When you zoom in, you see different objects and when you zoom out they disappear or they change their visual representation. For Roassal, we are thinking about adding new graphical elements when a particular height of the camera is reached. The elements will then disappear when the camera is getting altitude. However, it looks a bit simple in my opinion. Is there any compelling scenario for a better mechanism? Is there anything else you guys want to see in this zooming ability?

[Pharo-project] [ANN] humane assessment / moose courses
by Tudor Girba July 21, 2012

July 21, 2012

Hi, Humane assessment is a method for making software engineering decisions. Assessing software systems to make decisions is a critical activity that needs to be approached explicitly during development. Humane assessment is made possible by the Moose analysis platform. I am organizing a couple of courses in Bern that might be of interest to people on this list: Humane Assessment Primer (August 17) - This course is relevant for both managers and engineers. It covers assessment economics and the means to integrate humane assessment in the development process and in the organization - http://www.humane-assessment.com/courses/humane-assessment-primer Moose Apprentice (September 6-7) - This course is relevant for engineers. This is an introductory hands-on course on using the Moose analysis platform for putting humane assessment into practice - http://www.humane-assessment.com/courses/moose-apprentice If you are interested in participating, please contact me directly. Cheers, Doru -- www.tudorgirba.com "In a world where everything is moving ever faster, one might have better chances to win by moving slower."

[Pharo-project] glamorous inspector - extensions
by Tudor Girba July 21, 2012

July 21, 2012

Hi, I see that there is a bit of an interest in the GTInspector, so here are some extra info about it. Beyond the things you can do out-of-the-box with it, the true power of the inspector comes from its extensibility. The idea is to offer each object an easy way to exhibit its own characteristics. This changes the way you can think of interacting with objects. Some more details here: http://www.humane-assessment.com/blog/equal-browsing-opportunity-for-every-… A new feature is the ability to edit code directly in the methods presentation. Combined with the possibility of executing a method in place and previewing the result, this opens the door for a prototype-like programming style. The GTInspector is part of the Glamorous Toolkit. It is still in its infancy, but I think it shows that there is a great deal of possibilities to improve the IDE and to depart from the what we might think is a given. I am still looking for people interested in joining this effort (remember the idea of the ide taskforce). It would be great to get more people interested in improving this part of Pharo. Cheers, Doru p.s. You can get the Glamorous Inspector in the following ways: - download the Moose image: http://www.moosetechnology.org/download/4.7 - download Pharo 1.4 (summer) with the Glamorous Inspector: http://ci.moosetechnology.org/job/glamorous-toolkit-latest-dev/lastSuccessf… - load it in Pharo 1.4: Gofer new squeaksource: 'glamoroust'; package: 'ConfigurationOfGlamoroust'; load. ((Smalltalk at: #ConfigurationOfGlamoroust) project version: #development) load: 'GT-Inspector' -- www.tudorgirba.com "Live like you mean it."

Re: [Pharo-project] Customizing the Caret of a PluggableTextMorph
by Fernando Olivero July 21, 2012

Hi Phil. Excellent summary of the current mess! Yes, TextMorphs are the "views" , Editors handle the insertion/selection/menu logic, and Paragraphs lay out the text. I've replaced Paragraph, with Pango Layouts to reuse a more customizable layout engine, until some kind soul rewrites completely Paragraph (and friends) to be as easy to use (and powerfull) as Pango (which i doubt it will happen in the next decade). Denis, unfortunately i had to handle other stuff related to my phd, and still couldn't release Gaucho/Shapes, I'm working on it now again. Here's a presentation i gave @ the pharo conf [1]. Glad to hear that you want to try to use it for Presently, will be out soon.
