And yes, we will add real benchmarks at some point. But for that we first need dedicated machines, as running them on a virtualized environment doesn't make much sense :/.

Thanks esteban I will convert the blog into a draft chapter so that olivier can help documenting it too.

About validation

by StÃ©phane Ducasse

Hi I read the chapter on validation of the mentoring course book of andres valloud. http://www.lulu.com/fr/fr/shop/andres-valloud/a-mentoring-course-on-smallta… And I love this extension of SUnit. I loved the idea when I saw it for the first time at Lugano (presentation of Leandro Caniglia). I encourage everybody to read it. Now does anybody implemented in Pharo the SUnit extension? I would like to play with it and eventually write a chapter on it for the next book. The idea is so good. Stef

recompile a class via menu item in Pharo 2?

by Paul DeBruicker

In earlier versions of Pharo you could choose a refactoring scope and then recompile everything in that scope by choosing the 'recompile' menu item . Is there a way to do the same thing in Pharo 2? Thanks

How to split or rename Pharo categories with regard to Monticello packages?

by MartinW

Hi, i was looking for best practices on how to split or rename Pharo categories with regard to Monticello packages. Means, when i change category names i have to somehow reflect this in Monticello packages too? I asked on Stackoverflow: http://stackoverflow.com/questions/16981791/how-to-proceed-with-monticello-… http://stackoverflow.com/questions/16981305/how-to-split-a-package-category… but did not get any answers. So i repost the questions here. I found some similar - older - questions on the mailinglists, but was not sure if there were any news on this. /In Pharo 2.0 i started with Classes in one Package/Category (I'm not sure, what is the right term in Pharo at the moment). I have an identically named Monticello package which i contribute to. Now i split the Package/Category: MyPackage becomes: MyPackage-Core MyPackage-AddOns What is the intended way to manage these Packages/Categories with Monticello now? Is there a way to automatically split the Monticello packages accordingly? (I created some mess doing it manually and ended up starting in a new image and manually filing in the classes and then creating new Monticello packages)/ and /After renaming a Package/Category in Pharo 2.0 that is also under version control in a Monticello package of the same name, how to proceed? can i proceed with now renamed packages/categories in a Monticello package with an old, other name? can i rename Monticello packages accordingly with/without keeping the history intact? What i ended up with for the moment is, loading the renamed Package/Category into a fresh image, creating a new Monticello package there and losing the history./ -- View this message in context: http://forum.world.st/How-to-split-or-rename-Pharo-categories-with-regard-t… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
