Re: A question about packaging

by Kasper Osterbye

As Sven said it is done using categories. In practice I often use the small âextensionâ button in the lower right corner of the method editor of the browser. If you press that, the system comes up with a small menu of existing packages, and you can select yours. â Kasper > On 16 Feb 2021, at 21.08, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > > Hi David, > >> On 16 Feb 2021, at 20:49, David Pennington <david(a)totallyobjects.com> wrote: >> >> Hi everyone.

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

A question about packaging

by David Pennington

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? David

Hello David, We just sent an update and a blog post to get the new VM and install it. So let us know. I think that Pharo will be a lot snappier because Rosetta is slowing Pharo a lot.

StackVM for M1 ready

by StÃ©phane Ducasse

Hello happy Pharoers Today we could access our building where the M1 machine is and Pablo packaged it so that you can test the first version. Pablo wrote a little blog post for you. https://thepharo.dev/2021/02/16/first-apple-m1-pharo-version/ Let us since we do not have the M1 at hand and waiting to be able to make it accessible from our build farmâ¦ but we are not responsible for it and we were waitingâ¦. But the crew was fixing other VM glitches. So we will be ready soon to focus on the Jit version.
