PharoConf was held at Inria Lille the 24 and 25 of May 2012. Two days of Pharo, lots of talks, discussions and short presentations of companies using Pharo.

You can browse the slides (and see some photos snapped at the conference) here.

Today we'll take a look at Applications and Subapplications in VA Smalltalk. In most circumstances, you can just build configuration maps from "flat" sets of Applications, but there are times that you might want to create sub applications. The most common example is one that exists in the system as shipped by Instantiations - platform specific code:

What we are looking at is on Application - CommonFileSystem - and asset of sub applications. Some of them load regardless of the platform you are on, while others are specific to the platform you are on (Windows, Linux, Unix). Take a look at Application definition in ENVY:

What we have here is a set of apps for all platforms with configuration expressions that specify which ones actually load. The Subapplications are hierarchically organized under the main Application, but can be set up to load only when it's appropriate.

Today's Smalltalk 4 You shows you how to extend an existing class in VA Smalltalk without changing the owning Application. In VA/Envy, all classes are owned by an Application. If you change the class definition or an existing method, you have to change the owning Application. Today we'll look at adding new methods to existing classes in your own Application.

Today we'll look at how to extend existing classes in VA Smalltalk - organizing that code into your own Application/SubApplication instead of in the owning one. We've created a new Application and class, and a single method: #isFoo:

If you imagine this method as the kind of test that will be used to find out whether a given object is a "foo sort of thing" or not, then you see that we want a matching method like this:

isFoo
    ^false

In Object. However, we don't want to add that method to the Application that owns Object. Recall that in ENVY, class definitions are owned by the Application they are defined in. If you need to change and existing method or class definition, you have to create a new version of that Application. However, that's not the case if you merely want to add a new method

In your Application, select the "Classes" menu. Pull down to "Add", and you'll see "Extension" as a possibility. That's what we'll do here:

You'll then get prompted for the class you want to extend:

Finally, add the method in the browser - you've now extended a class owned by a different Application in your own Application:

How else do you explain this patent?

Apple secures a patent for the wedge profile sported by the MacBook Air.

I'll say it again: a system with no patents or copyrights would be an improvement over what we have now....

As we shop carefully for a new car (my old one finally died completely), we had a bit of inconvenient excitement with the one we still have - the electric window on one side is stuck - open. So much for parking it and leaving for the day :) Easy enough to get repaired, but not this late in the day on a weekend....
