Hi all,
is there some documentation, help, tools, etc. to port a Squeak app written in SqueakV2.sources to a recent image?
fileOut -> fileIn gives me all sorts of error messages I cannot understand/debug.
I actually just want to port parts of the app to re-use the code. But it proofs really difficult for me
Thanks, Matthias

Hi, in FileList you can try to look at the code with the CodeBrowser. Select the file you want to load, press the code button, or select browse code from the context menu. This will load the code in a temporary way and you can browse it and see the methods that change, and file in the parts you want.

Hi,
I already tried to fileIn a minimal part (one Morph class) of the application I want to port and started resolving the errors in the debugger one by one. Still, now I am stuck with the following error: Metaclass(Object)>>doesNotUnderstand: #category (the full Stack Trace is attached)
Were there some changes in the Metaclass between V2 and V3 that explain this error?
Thanks for the hint, though Karl. I didn't know about that possibility.
Regards, Matthias

This apparently happens after some syntax error already happened.
So the method being compiled has an issue. Then the question is to find out which method. In the debugger that produced the stack trace, visit somewhere at the bottom and see the content of aStream variable for Compiler>>translate:noPattern:ifFail:. The method should have some problem.
But it could be a subtle one... You could also define #category method at Metaclass that simply returns nil and then try to file in, I think.

I re-checked the errors I got before this one and I think I solved them alright.

I checked the method in the ReadStream of message, but couldn't make out any problems (it is attached, though).

I tried that before (with returning self though), but without any luck (I am getting: Metaclass(Object)>>error: ... "Error: Instances of Metaclass are not indexable").

Cool, it is a fun class to work on. I tried to file it in to 3.10.2 and did get the Syntax Error panel properly.
The trouble seems to me that in the following part and after, variable "n" is used but it is a block local variables in the previous blocks.
------------------------------ n _ root, part. ------------------------------ which is in: ------------------ "resizeable button/typein forms" #(paintUtilityButton) do: [:root | #(Left Middle Right) do: [:part | n _ root, part. pressed _ root, part, 'Pressed'. ScratchSkin at: n asSymbol put: (Utilities form: n from: aDirectory). root ~= #typein ifTrue: [ ScratchSkin at: pressed asSymbol put: (Utilities form: pressed from: aDirectory)]]]. ------------------
If you look at the Syntax Error window, there is "out of scope ->" indication in front of "n". In the older image like the MIT Squeak, it was forgiven but not anymore in the newer images.
So, rename the variable n in that part to something else and it should be fine.
-- Yoshiki
Wow! That's great. I managed to fileIn the class now. They did quite a lot of this variable saving stuff...

How do you get the "Syntax Error panel"? Is that a special tool? I'm only getting the debugger where I navigated to the message you told me...

n _ root, part.

Did you get a window like attached when filing in the changeset?
-- Yoshiki
No, I didn't. It's probably due to the image I am using!? Maybe the Syntax Error tool is not included? It is sq3.10-7159dev08.03.1.image

Now, I remember where it was started^^; So because #category that is used in the syntax error reporting mechanism raised an error, you didn't get the window, right?
You do have SyntaxError class in your system, yes? So, that must be a bug somebody introduced in the sq3.10-7159dev08.03.1.image.
-- Yoshiki
this is really strange. can you select one class of your app and fileout it and send it?

Hi,
attached is the class I tried to fileIn, which also throws the error.

Tested on 3.8 image: You can left click on the red text in the syntax error and proceede. Code seems to be dependent on ScratchPlugin . There is also a problem with StrikeFont initializion. If you leave a Trancript open you will see file in messages.
