[Pharo-project] [ANN] Spotlight like morph for pharo
by Guillermo Polito May 1, 2012

Fwd :) ---------- Forwarded message ---------- From: Esteban Lorenzano <estebanlm(a)gmail.com> Date: Mon, Jan 23, 2012 at 12:53 AM Subject: [Pharo-project] [ANN] Spotlight like morph for pharo To: Pharo Development <pharo-project(a)lists.gforge.inria.fr> Hi, I want to announce a little tool I made the other day (mainly because Mariano asked for it :) Do you remember algernon, that tool who was working in pharo 1.1 and is now obsolete? I used it all the time, and I always missed the ability to open browsers without having to type the class name in a workspace, or open a browser first, then look for the class. So, I created this: Gofer it squeaksource: 'Spotlight'; package: 'ConfigurationOfSpotlight'; load. ConfigurationOfSpotlight loadBleedingEdge. if you press shift+enter, you'll get a "spotlight" like morph, with a simple text input with OCompletion inside... is very simple and I think very useful. Of course it can be enhanced in a lot of ways... but let's here the community opinion first, and see if it worths to keep adding functionality.functionality. enjoy, Esteban ps: this is also an example of why I hate morphic so much (bah... current dirty implementation): I had to extend two classes just to change the editor used by a textmorph.... come on!!!!

Nautilus history combo problem
by Juan Ignacio Vaccarezza April 30, 2012

April 30, 2012

Hi all, First of all thanks for pharo 1.4 :D. Thanks for nautilus, a new browser easily extensible and "inside" the pharo is much appreciated. I still have few flight ours with smalltalk and pharo so please be gentle. Now the work I just downloaded pharo 1.4 and I loaded Nautilus browser by doing Gofer it url: 'http://ss3.gemstone.com/ss/Nautilus'; package: 'ConfigurationOfNautilus'; load. (Smalltalk at: #ConfigurationOfNautilus) loadRelease. Everything goes well, I can use Nautilus. But I'm getting a nasty behavior when I click the history combo after seeing the groups (by the way I love this abstraction). The nasty behavior is that all gets stuck, and for a reason I can't explain neither the user interrupt is responding. Cpu usage goes to 100%. (An endless loop?) I can live without the history combo but when I accidentally click it all gets stuck and i should restart pharo, get the changes I couldn't save and is totally annoying. Should I create an issue here: http://ss3.gemstone.com/ss/Nautilus.html/Issues?_s=YPZfki8fT3W4N7gS&_k=zY4N… I will investigate a little further but as I said I'm pretty new at this. Regars, Juan

Is there another browser ?
by Roger Gilliar April 28, 2012

April 28, 2012

I was wondering if there is a browser that - let me rename methods - supports code completion - generate getters and setters for selected instance variables - supports refactorings ? Regards Roger

This is unfortunate, but there was not any real alternative... You can load though better browsers: 1) OB. In the Configuration Browser there is a configuration to load it (this is the browser form 1.3 full) 2) Natilus. This is the browser we will ship by default in the future. You can load it yourself (There is a config in the Configuration browser). 2.0 will come with Nautilus by default. You can already play with it here: https://ci.lille.inria.fr/pharo/view/Pharo%202.0/job/Pharo-2.0/lastSuccessf… But keep in mind that this is under heavy development.

Pharo conf. Social Event
by StÃ©phane Ducasse April 28, 2012

April 28, 2012

Hi, For the conference, the lunches and coffee breaks are covered by INRIA and EMD. Now I would like to organize the social event for the thursday evening. Now our team cannot cover it because our budget is tight but I can have a really good restaurant (I know personally the cook). We could have a really good diner for around 30-35 Euros (with a cook cooking everything live in the back). Now I need to know who would like to join. You can come with your partners. So please let me know because like that I can book the restaurant. Stef

Drag and drop events in Pharo
by Christian Caldeiro April 27, 2012

April 27, 2012

Hi, I've made a small experiment, dragging a file to Pharo's window, which caused to instantiate a FileList object (shown as a pop-up window) with instance variable reference containing a FileReference object corresponding to the file chosen. (Does this make sense?) The question is, how can I customize this to get this FileReference instance and assign it to some arbitrary class instance variable? In other words, how does the dnd event work in this case? Thanks Christian

Script Manager
by Scott McLaughlin April 26, 2012

April 26, 2012

Hi All, InÂ PharoÂ 1.3, under the tools menu, there was menu item 'Script Manager'. Script Manager was a nice little tool that allowed you to organize and keep a series of workspaces. I don't see this in 1.4. Is it still there someplace or is it gone? Thanks, Pharo Rocks, Scott McLaughlin

[ANN] ImageWriter, the SystemTracer's son
by Guillermo Polito April 26, 2012

April 26, 2012

First public push of the first step of the hazelnut GSoC project :) *In a nutshell* For those who didn't know SystemTracer (the father): It is a tool that traces a graph of objects and writes an image from it. ImageWriter is a refactored, renamed and repackaged version of SystemTracer2 with the following changes: - The image format can be provided as a parameter. - You have to provide an SmalltalkImage object as root to write the image (so in the future we can write bootstrap with this). - The object format was reified in objects. So the code is easier to understand + change, and people can learn how are our objects in memory easily :D. Right now, only 32 bit image format is supported. *Structure* - ImageWriter-Core has the image formats and the image writer in itself - ImageWriter-ObjectFormats contains objects that represent the memory layout of the objects and it's headers. - ImageWriter-Tests has some tests. *Tests done* - Only tested in Pharo-1.4 - There are specific tests written for the size and headers of the objects - Also, I've written a Pharo-1.4 image and then run the tests in the copied image. Only one failure compared to the original :) *Known Bugs :)* - WeakRegistryTest>>#testFinalizationWithOnFork is failing, and when I run it manually it works :/. In the image I use to write, it does not happen, only in the clone. - When opening the new image, the window is too small. It is not respecting the original image size. Don't know yet what is the problem. *How To Download* Gofer it squeaksource3: 'ImageWriter'; package: 'ImageWriter-Core'; package: 'ImageWriter-ObjectFormats'; package: 'ImageWriter-Tests'; load *How to Use it* HzImageWriter new format: HzCogImageFormat new; "or HzInterpreterImageFormat new" imageFileName: 'someFile.image'; onInitializeDo: [ "Some initialization?" ]; "this is optional, probably the same as an startup script, probably nonsense" writeImage: Smalltalk "Yes, we provide the our lovely global Smalltak, but any SmalltalkImage instance could be" *Next steps on this direction* - support to write an isolated image different from the host one (I'll know what I need later, hehe) - class comments! - metacello configuration - better api :) *Links* http://ss3.gemstone.com/ss/ImageWriter.html Cheers, Guille
