Hi everyone. I have been using Pharo sine I got my M1 MacBookAir in late December. Before then, I was a VAST user since around 1995.
I have a question about packaging. Example, in VAST, I have an Application called Family_Accounts. Inside that I have some classes such as FAEntry, FABudget and so on. If I wanted to extend String to add an instance to convert to ScaledDecimal but using my special amount strings. I select the New menu item and then select either a class or an extension. As I want to extend String, I select Extension and then, within my Family_Accounts, I can see the String class so that I can extend it.
In Pharo, I can have a package called Family_Accounts. I can extend String, OK but my extension stays within the original package with, optionally, a Family_Accounts classification. I canât see how to add String to the Family_Accounts package to keep everything together in one place. Can this be done?

Extension methods are placed in method categories named after the package, *Family_Accounts. With the Calypso Browser, the UI hides this. At the bottom right there is a checkbox to make your method an extension and to chose the package to place it in. It can be a bit hard to use or confusing, but it does work. Also, once you have extensions, they will show up as a virtual package (sub) category, which is very nice to get an overview. I am sure this is described in some documentation somewhere. Sven
