Re: [Pharo-project] refactoring

You have to install a browser with refactoring support, such as Nautilus. Open the configuration browser and load it from there :).

[Pharo-project] refactoring

by blake

OK, I've got a clean Pharo 1.4 (plus seaside) and need to refactor some code. I haven't changed the defaults. It looks like there are settings for refactoring, but I don't see how to actually invoke anything. I'm used to seeing the options in the context menu. ===Blake===

This misses the fact that a MethodReference and a CompiledMethod are two different things *because* methods can be redefined. So if one holds onto a method that gets redefined one can have more than one method with the same name. However, a MethodReference always refers to the method that is currently installed. In this way a MethodReference is a pointer, a coordinate, but a method is a referent. Personally I think the distinction is important; browser tools should use references, not referents. > But the tools use Ring... somehow I thin it's odd that the inner workings of Traits used MethodReference (it was just because methods have no selector...)

In 2.0 we will integrate the event refactorings we did to start to be able to think about event dispatch. Fernando built state machine on top of our enhanced events. Fernando state machine idea for handling events is probably the way to go.

I loaded the config and it went fine. Got the NBCogVM from Jenkins. But then, got issues with the 1.4 image. FSFileSystem isn't in. What to do? And then, after commenting out the offending part, I end up with Error: function unavailable in NBFFICallout - This by running: | m | m:= AthensDemoMorph new openInWorld. m nextFigure. m delete. This is on Windows XP SP3. Do I need something extra? Is it not supported on Windows?
