I think most of the community is working on positive thinks (like you). Naming preferences and conventions shouldn't be a place for holy wars. And in fact I would like to learn more about Smalltalk Style, for example, how to use prefixes in classes without loosing the "branding" behind names and tools. Cheers, Offray

Re: [Pharo-users] What next for Pharo vm?

Smaltallk/X provides that Smalltalk/Java code duality. But I think if Pharo ever pursues that path the best thing would be to make it run in a VM such as Truffle/GraalVM [1]. A longest path maybe, but you'll be able to piggyback on an existing community of VM developers, and be able to interact not only with Java but it other languages as well.

It is not hard at all, just start from FileSystem (i.e. FileReference, FileLocator, etc, ..) and open your streams from there and you are good. I guess the FileSystem from the Deep into Pharo book is a good start. >From a user perspective, the changes are not that big.

I think that I will simply stop to read this mailing-list too. Like that I will get focused and do not get hurt systematically by all the wish list and santa klaus dreams around. I'm a bit feedup about the stream of "YouShouldDoIt" and also the ton of certain mails.

Steph has said the same thing to me multiple times about talking vs. action and I've worked on hundreds of issues. It can be frustrating, but I certainly believe it's worth it because while not perfect, Pharo is the closest to my Dynabook dream with enough of a community around it to have good up-to-date libraries around it, etc. GT, Roassal, Grafoscopio, and the new AI stuff are getting really exciting.

Re: [Pharo-users] question re. meaning of 'self' in a method used for testing

Indeed TestCase is a really a special class and it can be really looking strange at first. On Sun, Apr 22, 2018 at 2:20 PM, Sean P.

A migration guide will be more than welcome, because the API, and likely the logic, is different.
