Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages Perl, Smalltalk, Eiffel, Ada, and Lisp to form a new language that balanced functional programming with imperative programming. Smalltalk’s Big Ideas. To understand just how revolutionary the ideas of Smalltalk were, you have to try to put yourself back into the period when it was developed, in the 1970s, at a time when computer screens showed nothing more than green text on a black background and mice were things that lived in skirting-boards and ate cheese. Ruby has a very clean syntax that makes code easier to both read and write than more traditional Object Oriented languages, such as Java. For beginning programmers, this means the focus is on the meaning of the program, where it should be, rather than trying to figure out the meaning of obscure characters. Smalltalk has the cascade syntax, which Ruby lacks. Perhaps this lack is not as costly to Ruby programmers as it would be to Smalltalk programmers if the cascade syntax were dropped from Smalltalk, because in cases where the receiver is self, a cascade would buy nothing in Ruby because you can leave out the receiver in those cases anyway.
Is this true? I mean, are there any differences between ruby lambda and smalltalk block? If this is true, then what is a ruby block? Update: From the comment and answer below, together with some googling, I guess I have more understanding of Ruby block. In Ruby, usually a piece of code evaluates an value, and every value is an object. But. De plus, le Smalltalk est un méta-langage car il se décrit lui-même et la notion d'image permet d'éviter les problèmes de fichiers et de chemins. Le principal inconvénient du Smalltalk est le typage dynamique. En effet, cela peut dérouter le développeur débutant habitué à respecter le type d'une instance et à déclarer une variable.

Smalltalk was designed as an operating system, though it's typically run as an application inside another OS. This is not unusual. I remember years ago hearing about a version of Linux that was installed on CD that ran as an application inside Win. It's also a good example of why Smalltalk is superior, there's not much you could think up that you couldn't simply add to Smalltalk, implemented in Smalltalk. If Ruby didn't have traits, I don't think you could add traits by hacking a litte Ruby, especially since much of Ruby is implemented not in Ruby, but in C. Smalltalk is a language that. Since metaclass objects do not behave differently you cannot add class methods for a metaclass, so metaclass objects all have the same methods, they are all instances of the same class—the metaclass of the root class unlike Smalltalk. Thus, the metaclass of the root class is an instance of itself. The reason for this is that all. Ruby's Roots: Smalltalk Comeback and Randal Schwartz on Smalltalk. A recent blog post by Gartner Analyst Mark Driver picks up on the increasing interest in Smalltalk. A recent blog post by Gartner Analyst Mark Driver picks up on the increasing interest in Smalltalk.
Smalltalk, a language that has had a big influence on Ruby, is making a comeback. We take a look at the current situation and talk to Randal L. Schwartz about Smalltalk.
27/10/2011 · Martin McClure Abstract At GemStone, we implemented our MagLev Ruby server by adapting our Smalltalk implementation until it now runs both Smalltalk and Ruby. Ruby's semantics resemble Smalltalk's. In Ruby whenever you create a class, Ruby internally creates a corresponding new class called the “metaclass.” Unlike Smalltalk, Ruby doesn’t use this for class instance variables, but only to keep track of class methods. Also, Ruby doesn’t have a Metaclass class, but instead all metaclasses are simply instances of the Class class. I thought it would be an interesting idea to have a presentation where we compared Smalltalk to one of our dynamic language cousins. Of these next kin it seemed to me that from the most popular languages that Ruby was the closest.
Ruby est en train de devenir popular, en grande partie grâce à l'influence de Ruby on Rails, mais on a l'impression qu'elle se bat actuellement à travers son adolescence. Il y a beaucoup de similitudes entre Ruby et Smalltalk - maglev témoigne. En dépit d'une syntaxe plus inhabituelle, Smalltalk a tout sinon plus de la beauté orientée objet de Ruby. Smalltalk-80 byla první verze, která opustila PARC, nejprve jako Smalltalk-80 Version 1, ji dostali na přezkoumání a otestování některé vybrané společnosti Hewlett-Packard, Apple Computer, Tektronix a Digital Equipment Corporation a univerzity. Smalltalk-80 Version 2 už byla vydaná jako tzv.
Smalltalk introduced the world to the language virtual machine, on which Java and Ruby are based, as well. Smalltalk pioneered JIT just-in-time compilation. From Smalltalk came the first modern IDE integrated development environment, which included a text.
