There's also a keyboard shortcut if you're looking for a string literal; try selecting that text (eg in a workspace) and pressing Cmd+Shift+e (on a mac, I think this translates to Alt+shift+e on windows/linux). That should launch a case-sensitive search for that string.

Hello,

I have always wanted the ability to sometimes just search the image for a string of text. Just like I would in an OS per se.

I might see a morph that has some text in it and I want to know the code from whence it came.

Or any other number of reasons.

Is there a way to do this?

As Squeak is OS like in many ways, it seems like this would be there.

Any wisdom greatly appreciated.

Hello,

I just went to try this and in the latest squeak-dev image when I see the above menu option they say:

Method strings with it Method source with it

I knew I had multiple ways of searching source code, methods, classes, etc. But there is also much in an image which isn't in source code.

Instance variable values are not source code but can be in an image.

What if I wanted to find an instance which had a variable which contained a certain literal string? Can I do that?

While I am at it.

Can you find or browse the source code for things not created in a browser?

eg: Say someone more experienced than I wrote a small Class in a Workspace. Possibly closed the workspace, possibly after creating an instance of said Class. Would it show up in a browser? If not how would you access such again?

Or access anything created in a Workspace and the particular text was deleted or the workspace closed?

Thanks for any wisdom.

I'm sure I'm not the only one lacking understanding in these areas.

I don't know if any of this is covered in the SBE I am about to receive or not. Or if stuff like this covered in other Smalltalk texts.

Again, thanks.

Jimmie

Thank you, thank you, thank you.

Very informative and enlightening.

I will most definitely begin using this knowledge. :)

This is tremendous. Very, very sweet. :)

Thanks.

Sure thing. All objects in the image are accessible and can be enumerated, and references traced. This is what inspectors and their friends are for. You need to get a reference to your String first:

String allSubInstances select: [:s | s = 'Kernel']

Press Cmd-i to get an inspector on these strings, it's 11 in my image. Or use this to match substrings:

String allSubInstances select: [:s | s includesSubString: 'Kernel']

Select one string, and in the menu select "objects pointing to this value". This will get you all objects referencing that string. From there you can continue to follow these references "backwards". A cool tool to do this is the pointer explorer from the same menu which lets you explore where objects are referenced from.

Btw, I once closed a valuable workspace with some long series of expressions in it. I used the #allSubInstances "trick" to get it back before the garbage collector could free it :)

There is no difference between classes created in a browser and those in a workspace. You have to understand that neither classes nor the browser is special - Everything Is An Object. The browser happens to be an object that manipulates class objects, just as you would do in a workspace.

Thanks,

I don't know that I had seen that before. Some of the browsers don't have it.

But if I had I wouldn't have thought to use it, as what I am wanting to understand is how to search for those things that are inside of the browser world.

I will have to spend some time using this little tool.

Thanks again for pointing it out to me.
