如何在Smalltalk中打印作为参数发送给类方法的字符串

Question

I'm trying to write a class method which recieves a string and prints it. I've tried this:

log: aMessage
Transcript show: aMessage; cr.

and tried to use it as follows:

ContractObject log: 'aaa'.

(ContractObject is the name of class) but it didn't work. I'm assuming it has something to do with the fact that it's a dynamic language and that it's not known that it's a string. I tried to convert it etc. Nothing worked.

Answer 1

No, types are definitely not the problem here. What do you mean by "it didn't work"? What was the error message you got? Did you get any at all?

Do you have the Transcript open? If it's not open you wont see anything. You can open it programmatically by evaluating Transcript open or manually by using the menu.

Also, make sure that you have implemented #log: on the class side (that's what you see when you click the class button in the code browser).
