Not a text editor, but there was a ScriptManager that was kind of a worksapce with ability to give scripts a name, save them, and then easily browse and execute them. But this is a bit old, so not sure if this still works in Pharo 4.0: http://pharo.gemtalksystems.com/book/PharoTools/Script-Manager

Thank you for sharing your experience with it. So, when I see all this, I think depending on initialize method on class side seems like a pretty bad idea.

Re: [Pharo-users] Pharo and Hadoop

Having Pharo playing there seems to be a good place to show its strengths. However, you mentioned too many acronyms of technologies I don't understand (but hear a lot about). The only thing I can agree with is that the self-contained nature of Pharo is a true advantage when deploying extra nodes.

Hi, SomeClass and SubClass are two different objects. Based on your setup, if you do not call any initialize method, initially calling both "SomeClass isOk" and "SubClass isOk" should return nil. Running "SomeClass initialize" initializes only the SomeClass object. So now "SomeClass isOk" retu
