Did you find it easy to read? I'll bet you also found it hard to write. If you look at the file-out format (also called chunk format), you can just simply write the code you want as a result and it would be infinitely more comprehensible to you and to those you would share it with. There are times when writing things along the lines that you have are essential. For example, if you are writing a code generator you would want to generate source strings and compile them. -- View this message in context: http://forum.world.st/New-to-Pharo-a-bunch-of-questions-tp4917701p4917927.h… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

They are tools for interacting with the objects in the system, just as are the debugger and inspector. That being said, I do agree i is important to understand how the tools do what they do. You should definitely browse the Behavior hierarchy. It contains all the code for creating classes, compiling (and installing!) methods, removing methods, and so on. Also, I noticed in your examples that you like to write ([ ... ] value). Why? Why not just write the actual code (shown as ... in my example)? > Personally I've never had more fun with Smalltalk as I did writing this > proof of concept. -- View this message in context: http://forum.world.st/New-to-Pharo-a-bunch-of-questions-tp4917701p4917926.h… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Well, be sure to check out the Toronto Smalltalk User Group! http://www.smalltalk.ca/ says they meet at Ryerson. I'm not sure that's always / still true.

How does Pharo store instance variables?

by CodeDmitry

I am trying to study Pharo's internals and I am now curious how it stores class variables. I notice that in order to have a class `Greeter` with a "static" variable `greeting`, I need to make `greeting` an instance variable under "show show the class side" and create a "Getter" and "Setter" for this "instance variable". First thing that confuses me is, why is this called an instance variable if this particular "static" method is not bound to any particular instance? Is it just because it is defined in an "instance" of a "ProtoClass"? Second thing that confuses me is, where are these pairs of ("instance variable name" => "instance variable value") stored? I know that I can call Transcript show: ((Greeter class) instanceVariables at: 1). which prints "greeting". and Transcript show: Greeter instanceVariables class. which prints "Array"(curious, i expected a Dictionary mapping Strings to Object). Transcript show: ((Greeter class) instanceVariables at: 1) class. prints "ByteSymbol". Now I am confused, where are the actual values of the "static variables" stored? I can find the names, but can't understand where the values are hidden. Can somebody help me understand this? -- View this message in context: http://forum.world.st/How-does-Pharo-store-instance-variables-tp4917924.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Excellent :) We did not know that Ryerson was using Pharo!
