[Cuis-dev] Hello, new Cuis smalltalk user here!

Hey Bruce,

Thanks for the explanation. The reason I ask this, is that I plan to read or should I say, have been reading "The Blue Book" alongside "The Cuis Book". I just don't want to confuse myself and thinking that I'm getting dual-learning for Cuis. I will admit that using " official" smalltalk-80-V2 is appealing for its retro look and again, simplicity, but I do have to say Cuis is more practical I think. From what im getting learning from the book, is that learning this language is a lot of exploration, and that may be true for most languages, but their learning styles are more obvious on what does what and how to put together this with that (some of the comments on methods are not clear to me so, as a novice I'm kinda confused). This might sound bad, but to me, this is where the beauty is. I like that I'm thrown into a world that I get to explore and figure out on my own how this puzzle piece fits with this other puzzle piece. What I get is "here is the blank piece of paper, this is how you write a paragraph, figure out how you want to write it". I could be wrong but that's what I get from the language. So for me, using Cuis or " original" smalltalk-80 both would satisfy that condition. I like Cuis more though :).

Regards,

Joseph Turco

I'm pretty sure that none of the open source options out there, despite their claims, *really* offers 100% Blue Book compatibility. Cuis (and Squeak) probably offer reasonable to very good compatibility through chapter 16. There may be some differences here and there, but this is pretty core stuff that I don't believe has changed much. Chapter 17 on is mostly going to be very different and not something you're likely to find in today's implementations. Conceptually, most of the functionality still exists but when Squeak moved to Morphic most things got renamed/restructured/rethought. In the 25 years since, things have continued to evolve even further away from those later chapters in the book.

I understand Cuis is supposed to be close to smalltalk-80 (which I like due to simplicity), but the reason I ask this question, is, could one read "the blue book" to learn Cuis, or is it better to run an original smalltalk-80 VM (like the C++ implementation and the crosstalk bare metal for raspberry pis)?
