Does anybody know what's the newline delimiter for a string in smalltalk? I'm trying to split a string in separate lines, but I cannot figure out what's the newline character is smalltalk. ie. string := 'smalltalk is a lot of fun. ok, it's not.' I need to split it in: line1: smalltalk is line2: a lot of fun. l...

I am trying to compare two strings in Smalltalk, but I seem to be doing something wrong. I keep getting this error: Unhandled Exception: Non-boolean receiver. Proceed for truth. stringOne := 'hello'. stringTwo := 'hello'. myNumber := 10. [stringOne = stringTwo ] ifTrue:[ myNumber := 20]. Any idea what I'm doing wrong? ...

I am really interested in GLASS. The 4GB limit for the free version has me concerned. Especially when I consider the price for the next level ($7000 year). I know this can be subjective and variable, but can someone describe for me in everyday terms what 4 GB of GLASS will get you? Maybe a business example. 4 GB may get me more sto...
I've never used Smalltalk, but I've read a lot about it and it has always intrigued me. I've seen the cool demos where a program is running and simply by changing the methods of the classes the program's objects are using alters the running program's behavior. It's clearly powerful stuff and I understand how that can work the way it does...
One of the annoying things about Smalltalk is that it (usually) requires its own VCS, due to the way that it manages its source code. Squeak and Gemstone (at least in its GLASS version) have a DVCS called Monticello that works passably well. As near as I can tell, VisualWorks' main VCS, StORE, only works in old-fashioned centralized mo...
Hi, I'm trying out Pharo's Phexample and I like it, but it feels clumsy to have half my unit tests in SUnit and the other half in Phexample. Does Phexample have like an import feature for my existing tests? ...

Squeak was once innovative by giving people more than a dull error message: a debugger and go figure out! However, nowadays there's a google, and now it'd rock to copy paste the error message, which is typically served as the title of a debugger window. How can I copy and paste that error message? ...
Can I tell Gofer to fall back to the local package cache when no internet is available? For example such that I can use Gofer it squeaksource: 'CodePhoo'; addPackage: 'CodePhoo'; load to setup an image when offline on the train? (In that case we can be sure that the packages are in fact available locally from a previous i...
In every technical publication, and on this site too, people are always comparing OO languages to Smalltalk. My experience is in Java: is Smalltalk so important that I should study it? ...
I'm familiar with the VisualWorks and Dolphin versions of Smalltalk, but have not previously used Squeak. I'm just familiarising myself with Pharo, which is a 'cleaned up' fork of Squeak. I'm used to having the facility in the Class Browser to show either only the methods implemented by a class or both the methods inherited and the meth...
Hi, I've seen this recently and now I can't find it … How do you set the class of an object to something else? --Update: Well, in Pharo! Like: d:=Object new. d setClass: Dictionary. Only that it isn't actually setClass. How can you modify the class pointer of an object? ...

This relates to the Dolphin variant of Smalltalk. I'm digging around in the image to try and figure this out but haven't find the correct method invocation yet and I'm hoping someone might be able to help shortcut this process. What I'm trying to do is to find all methods (either within the entire system or, preferably, just within...
I would like to start a Community Wiki on good resources for programmers new to Smalltalk. I'm especially looking for good forums and/or mailing lists for programmers that are new to Smalltalk. Please correct me if I'm wrong (this is a wiki after all), but what I've found so far seem to be geared toward current Smalltalk programmers than...
What are the various sites that offer metrics that compare Ruby, Python, Perl, Smalltalk etc. What are their respective metrics? Do any of them control or account for the time that Rails was introduced, and/or the adoption rates for various languages? Will someone please help me close this question? Clearly it was not a successful vent...
