Re: [Newbies] Explorer and MessageTally [was: remembering variables]
How do I use TracingMessagesBrowser? If I try to install it with 'Squeak Map Package Loader' I get Error: No installer found for package. (this happens in every image that I've tried). If I try to install it from MC I open the repo and click on the mcz and squeak hangs. when interrupted it says it was in HTTPSocket(OldSocket)waitForDataUntil: I noticed TracingMessagesBrowser is in the FunSqueak image so I tried that but I don't see any way to open it. So confusing. Thanks in advance for your help. ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners

Re: [Newbies] Explorer and MessageTally [was: remembering variables]
I found something explaining the TracingMessagesBrowser and it works in the FunImage, but I still can't install it in any other image. When you browse Squeak code, one of the browsers you will invariably use VERY frequently is a Methods browser. This browser appears whenever you browse senders or implementors of a method, or references to a class or variable, among other things. It is a two-paned browser, methods list in the upper-pane, code in the lower-pane. So just keep exploring code normally, the next time you use senders or implementors (something any Smalltalker does about 1000 times per day) you will see the Tracing Messages Browser. These browsers look the same initially, but by having the traceMessages preference set, they take on enhanced behavior as you trace method calls. The SqueakMap entry describes it well: I look like a standard methods browser with methods in the upper pane, code in the lower. As you browse senders and implementors, the upper pane is built into a stack rather than opening new method browsers, reducing window profileration. Implementors are indented below the currently selected method, senders are outdented above. You end up with a flow of the execution of methods across multiple classes all in one place. The stack is quickly customized by easy-removal of unwanted methods. First, the upper pane is multi-select, and can handle rapid, sweeping gestures of the mouse without dropping selections (shift+clicking is also supported). Once methods are selected, you can quickly remove them (just from the browser) with otherwise unused Command+f. I think this browser has saved me years of closing windows. ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners

TracingMessagesBrowser don't open new windows. Instead, when you navigate the system looking for senders or implementors, etc, all go to top window instead opening new windows .

And I thought that generally they would otherwise things would get really confusing!? For this part of your question use Squeak's explorer. Try (World explore) to get an idea what it is about, for example expand the submorph branches that you see there. Sometimes when I try to understand how a program is working I get lost in the debugger. What I'd like is a kind of overview of what's going on. For this part of your question try (MessageTally spyOn: [Object compileAll]). Something I can browse and focus in on the parts that seem interesting. For MessageTally the parts of a computation which really do something are interesting. In theory I can do this with the system browser but it doesn't tell me how everything fits together. I want to see an overview of how all the parts fit together.. Who uses what.. Which bits are connected.. The order in which things are done, etc. MessageTally tells you how the parts of your computation fit together, who's using what, and the order in which things are done. Can I get the debugger to show a tree of message sends, that I can browse? Something like that? Yes, MessageTally does that for you: a tree of message sends. From the Spy results, you can select a class and browse it for more details, or a method and browse its senders or implementors for more details. Any ideas? thx. peter == peter h meadows [EMAIL PROTECTED] writes: peter Oh. I'm still very new to smalltalk. It seemed like it would help me to peter understand what's going on. I wanted it to remember everything. E.g if peter the thing is an array it will tell me what has been stored in it. Also, peter wouldn't it help with code completion? If it knows what type of object peter it was in the past it can guess which messages I want to send to peter it. That would be useful. But the problem is that a given type in the past is not any indication of a type in the future. You're not thinking smalltalk yet. Stop worrying about types. :) Oh, and they aren't types. They're instances of classes. If you want to see what's going on, learn to single step in the debugger. It's quite informative. ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners
Re: [Newbies] Explorer and MessageTally [was: remembering variables]
Hello Klaus, KDW Yes, MessageTally does that for you: a tree of message sends. From the Spy KDW results, you can select a class and browse it for more details, or a KDW method and browse its senders or implementors for more details. interesting idea to use it this way! But MessageTally IMHO only shows what it finds on the stack when it peeks. So it can miss some methods running seldom and quick. So you can do MessageTallytallySends: [your tallied block] which uses the simulator (sloow!!) but gets you everything. And to be real useful with long class names and deeply nested sends one might have to patch some of the class side methods of MessageTally in the defaults category. After looking I see it has become better with 3.9 so the latter applies only for 3.8 and older. -- Cheers, Herbert ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners
