I'm trying to grasp the concept of continuations and I found several small teaching examples like this one from the Wikipedia article: (define the-continuation #f) (define (test) (let ((i 0)) ; call/cc calls its first function argument, passing ; a continuation variable representing this point in ; the program as the arg...
Has anyone gotten VisualWorks running under OpenBSD? It's not an officially supported platform, but one of the Cincom guys was telling me that it should be able to run under a linux compatibility mode. How did you set it up? I already have Squeak running without a problem, so I'm not looking for an alternative. I specifically need to ru...
I've been learning Squeak Smalltalk & have noticed that it's got a really faithful community and is used in some large academic and open-source projects, but I haven't found any examples of it being used commercially in any significant way. I'm curious about how this environment is doing in the world commercially. Maybe taking over older...
What do you think is a good IDE for learning SmallTalk? I'll only be using it as a hobby, so it has to be free. ...
My questions is simple! Would you start learning Smalltalk if you had the time? Why? Why not? Do you already know Smalltalk? Why would you recommend Smalltalk? Why not? Personally I'm a Ruby on Rails programmer and I really like it. However, I'm thinking about Smalltalk because I read various blogs and some people are calling Ruby so...
As I'm riding the wave of resurgence of Smalltalk (especially because many Ruby-on-Rails people are rediscovering Smalltalk and seeing Seaside as their next upgraded web framework), I get questions like "yeah, but how do I use my favorite editor to edit Smalltalk code?" or "Does Smalltalk still insist on living in a world of its own?". ...
Ruby is becoming popular, largely from the influence Ruby on Rails, but it feels like it is currently struggling through its adolescence. There are a lot of similarities between Ruby and Smalltalk -- maglev is a testament to that. Despite having a more unusual syntax, Smalltalk has all (if not more) of the object-oriented beauty of Ruby....
I downloaded Squeak, the Image file, and the Sources file, but I can't figure out how to write Smalltalk code. Is there something obvious I'm missing? Is Squeak even the right IDE for serious Smalltalk development? ...
Anybody know of an implementation of graph algorithms in Smalltalk? I'd like something that allows you to implement an interface on your model objects or something and provides algorithms for transitive closure, transitive reduction, topological sort, etc., etc. People end up re-implementing these widely-applicable algorithms so often,...
How do I get a BlockClosure in Squeak (I want to use BlockClosure>>callCC)? When I write [#foo] that is a BlockContext, what's the deal? Update: I have worked out that BlockClosure is a thing mainly of new compiler. Instead how do I work with seaside Continuations? I'm having problems, and any examples would be appreciated. Further u...
Are there any usable implementations of Smalltalk for the .NET runtime? ...
I see a lot of IoC frameworks for .Net and Java. Does anyone know why there are no equivalent frameworks for Smalltalk. This is more a philosophy question than anything else. I'm wondering if there is something in the Smalltalk way of doing things that precludes the necessity of having an IoC framework. ...
I've been developing a Smalltalk variant for just the fun of it and I wonder what would be a fellow stackoverflowers choice when it comes to targeting a back-end. These were my current considerations: .NET, JVM: These two VM's are mainly for statically typed languages and I assume it would be quite hard to target such a dynamic language...
A class I am taking currently requires us to do all of our coding in smalltalk (it's a Design class). On one of our projects, I am looking to do some things, and am having a tough time finding how to do them. It seems that what most people do is modify their own version of smalltalk to do what they need it to do. I am not at liberty to d...
Now when the Gartner analyst said Smalltalk is cool again and it is used more and more for the web applications with frameworks like in Seaside and Aida/Web, me as a Smalltalker I'm wondering how much my language is known among broader programmer community. ...
It seems that programming ON a mobile device (instead of FOR a mobile device) could be easier if a lisp existed that run on J2ME. Do you know any (preferably opensource) lisp/smalltalk apps? I searched the web and I couldn't find a working J2ME lisp. Is it so difficult to port it to J2ME? Thanks ...
When discussing the evolution of computer languages, Alan Kay says that the single most important attribute of his Smalltalk is late binding; it gives the language its malleability and extensibility, and allows inappropriate coupling to be refactored out over time. Do you agree? Are there compensating advantages for early binding that ex...
The code below continues many lines until it ends with a expected /veotherwise /vechoose. I started working on a development firm a little ago where they use this html version called vhtml. I have search the web but it brings different definitions for vhtml. I have seen some posts in Joomla about vhtml but they don't look like the cod...
I plan about implementing a dynamic linking into my smalltalk dialect. The problem is about getting message passing to work with dynamic linking. Message passing itself is as simple as this: message with a selector is sent to the object, the object picks up a method matching with the selector from it's protocol, it then process the data...
I'm having trouble in getting the singleton pattern to initialize a instance variable in smalltalk. (here is a link to another implementation for clarification) this is what I have: new ^UniqueInstance ifNil: [UniqueInstance := self basicNew. UniqueInstance: instanceVar := Object new. ]. that last line (UniqueInsta...
