[Pharo-project] definition or getSource for Class and CompiledMethod
by StÃ©phane Ducasse Jan. 11, 2010

Jan. 11, 2010

Hi I was looking at the video of laurent and what stroke me is that getting the source of class or a compiled method is not polymorphic. It would be good to support that. aClass getSource? aCompiledMethod definition? Stef

[Pharo-project] Nanosecond-level profiling in Pharo?
by Alexandre Bergel Jan. 11, 2010

Jan. 11, 2010

Hi! I am currently working on a new profiler for Pharo. The idea is to graphically renders a profiling using Mondrian. I hope to release it soon. When discussing with an expert in the field (Walter Binder), the question about time grain was raised. I am partly based on MessageTally, which has a millisecond grain. Anyone is aware of a finer grain? At the level of nanosecond? Does it makes sense since there is no JIT (yet)?

[Pharo-project] IPhone and other tablet PC ..or about Genie with the New event mechanism
by StÃ©phane Ducasse Jan. 11, 2010

Jan. 11, 2010

Genie was a great recognition engine developed by nathanael when he was at disney. It was impressive compared with HP tablet pc software. You could steer the complete UI with it. Nathanael went to show it to Smasung research labs and HP at that time. Just before the layoff of SqueakC from HP Genie - learns in one pass a gesture no need to rehearse or you to adapt - had sophisticated settings (display size, battery consumption, speed of the stroke) - context dictionary so the same gesture could have different meaning in different contexts - has a really good documentation this are some of the class comments http://www.iam.unibe.ch/~schaerli/smalltalk/genie/genieIntroduction.htm Now Genie needed a hook in the min event pasteUp loops so we removed the patch because it was slowly the complete UI. Now that we have a cleaner event model and hook I would really love to see how we could hook Genie in Pharo. Since they is an interest for iPhone and may be new tablet. Stef

[Pharo-project] TestRunner author while running tests
by Lukas Renggli Jan. 11, 2010

Jan. 11, 2010

The fact that the test runner sets the author name to 'TestRunner' while running the tests is really annoying. I write a lot of code in the debugger while running tests and then all the methods end up with the wrong author name. I would vote for changing that back to the old behavior.

[Pharo-project] offermenu and friends
by StÃ©phane Ducasse Jan. 11, 2010

Jan. 11, 2010

Hi guys andreas published in squeaktrunk the following changes Replace offerMenuFrom:shifted: by offerMenu:from:shifted: which takes an additional argument, the model to retrieve the menu from and perform the actions on. And I was wondering if this would not help to get a better handling of menu and their respective action. Stef

[Pharo-project] Allow or disable System Update in PharoDev images ?
by Mariano Martinez Peck Jan. 11, 2010

Jan. 11, 2010

It is a simple question. Do we allow that or not. Miguel wrote the pros and cons: Pros - Can fix bugs after release - Can aply improvements to the image after release. Cons - Can mess the image of someone by overwriting some overridden method. - Can accidentally update more than intended in someone's image We have to take a decision. Cheers Mariano
