Hello,
Are you getting tired to create unnecessary file outs when all you want to do is to take a look at the code in another image and to see the diffs? Here is what you can do.
* File in the attachment, * Open a FileList, * Select a .image file and choose 'browse in ImageBrowser' from the FileList menu, * Open the menu at the class pane of the ImageBrowser, * Choose 'add classes to list' and type the name of classes yo want to see.
From a help from InterpreterSimulator, the ImageBrowser reads the source pointers stored in the CompiledMethods in the image file, and get the code from its accompanying .change file. (All file operations are done in 'read only mode'. So, don't worry about breaking your image file.)
The convenient functions inherited from FileContentsBrowser, such as 'remove unmodified categories' are there, too.
ImageBrowser works for M17n images as well.
I happened to notice the recent discussion about 'Diff between two change sets'. This ImageBrowser helps you to get diff between two images:-) Hooking up the internal machinary of this one with Bob's Comparison Browser would be interesting, (although I couldn't find an image to test it.)
Let me know any suggestions and comments,
-- Yoshiki
P.S. My email address has changed.

Hi Yoshiki,
This is a cool idea. Thanks.
I guess this tool only works on image of the same version and with a change set only.
It would be nice if I can use it to browse a headless image with no source and change.
Is it doable ? Would you consider that as a feature request.
Cheers,
PhiHo.

Hello,
Are you getting tired to create unnecessary file outs when all you want to do is to take a look at the code in another image and to see the diffs? Here is what you can do.
- File in the attachment,
- Open a FileList,
- Select a .image file and choose 'browse in ImageBrowser' from the
FileList menu,
- Open the menu at the class pane of the ImageBrowser,
- Choose 'add classes to list' and type the name of classes yo want to
see.
From a help from InterpreterSimulator, the ImageBrowser reads the source pointers stored in the CompiledMethods in the image file, and get the code from its accompanying .change file. (All file operations are done in 'read only mode'. So, don't worry about breaking your image file.)
The convenient functions inherited from FileContentsBrowser, such as 'remove unmodified categories' are there, too.
ImageBrowser works for M17n images as well.
I happened to notice the recent discussion about 'Diff between two change sets'. This ImageBrowser helps you to get diff between two images:-) Hooking up the internal machinary of this one with Bob's Comparison Browser would be interesting, (although I couldn't find an image to test it.)
Let me know any suggestions and comments,

P.S. My email address has changed.
PhiHo,

No, no, there is nothing that depends on specifically 3.2 or even 3.x, except a line in #openSourceFilesForImage: which specifies the .sources file name. As long as corresponding .changes exists, it should be possible to load V2 image onto V3 and vice versa.
I don't quite get what you mean by "with a change set," but that the way it works.
It would be nice if I can use it to browse a headless image with nosource and change.
Yes.
Is it doable ? Would you consider that as a feature request.
If you look at the class comment of ImageBrowser, you'll find the answer:-)
I think it is not actually that hard. All you have to do is to write a modified version of InstructionStream and Decompiler which access the bytes and bits through the interpreter simulator's #longAt: and #fetchPointer:ofObject: and alike. The bytecodes are just same byte value. The literals have to be located in the simulated image, but it should be too hard.

P.S. PhiHo, if you are going to reply my email, please include the entire part of this message. I still have a suspision that this one won't go through the normal channel. Thank you,

I have quite a few of 1.x and 2.x and 3.x images on my machines (with full source and changes files) only the 3.x work as expected.

Sorry, I meant .changes file. :-)

Just read it and got all that I want to know ;-)
Thanks for the tips, Yoshiki.

I received only 1 copy of your mail, so assumingly it did not get to the list.

I actually hadn't tried^^;, but you can load 2.x image onto 3.x image, once you change the #openSourceFilesForImage method, right?
To load 3.x image onto 2.x image, which sounds more useful than the opposide, requires some tweak.
The best approach would be to add a flag that tells which version (loaded image or loading image) should be treated as the "base" one and which is "new". Then we wouldn't have to worry about making different versions of ImageBrowsers or back porting FileContentsBrowser to the older images.

I'm sending this with my ISP account's From: line to see if the From: line is all that matters... Thank you for all of your helps,

I can load 2.8 image without changing the #openSourceFilesForImage method.
Only when I add class, then there is a problem. Please find attached log file.

An image editor is even more useful ;-)

Thas is exactly why you have to modifiy #openSourceFilesForImage. The source code for a same method may be in differerent file offset in V2.sources and V3.source and if the system trys to extract the source code for V2 method from V3 source, it is screwed.

We call such editor as InterpreterSimulator. So, we already have it:-)
