[Pharo-project] 2.0 is back in "usable" state
by Esteban Lorenzano Sept. 20, 2012

Sept. 20, 2012

Hi guys, I think Pharo 2.0 is back in an usable state :) Beware, that doesn't means that it is stable and bug free! In particular, I think there are still some problems around RPackage and the new SystemAnnouncer, but you can resume using it and providing bug reports/fixes. Enjoy, Esteban ps: That means tomorrow I will resume the integration of issues, etc. but the stability effort is still ongoing...

Sept. 20, 2012

hi! Is there a reason why this method has been removed in 2.0? I checked the google code site and I could not anything related to this. Maybe it has been added in 1.4 without being added to 2.0. Shall I provide a .cs with the method? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

[Pharo-project] [Screencast] Roassal, an agile visualization engine
by laurent laffont Sept. 20, 2012

Sept. 20, 2012

Roassal graphically renders objects using short and expressive Smalltalk expressions. A large set of interaction are offered for a better user experience. Painting, brushing, interconnecting, zooming, drag and dropping will just make you more intimate with any arbitrary object model. Thank you Vanessa PeÃ±a ! http://www.pharocasts.com/2012/09/roassal.html Laurent

Why would anyone want not to look at all methods in a class by default? In well refactored code, the number of methods is so limited that no scrolling should be needed. Not all code is like that, of course. Reading code is the most important activity of developing, and it is essential to limit the interaction needed to browse through code. Much better would be to show in the code pane which instance variables have accessors (r/w) and show all without accessors by default. > > However I can see that a "classical" user might be disturbed.

Why can not showing 30 items in a list make a difference of 200 ms? Stephan
