No webserver started when starting spoon
by Norbert Hartl 19 Nov '07

19 Nov '07

Hi, finally I tried the latest spoon release. I took the start instructions from the README.html. Starting the memory.image I get an empty window but there is no socket opened on 8090. so I couldn't connect with the browser. My system is ubuntu linux 7.04 (feisty). Norbert

Hi Janko-- > When Spoon will be ready and proven on few battlefields, then will be > a time for a switch. Can you be more specific? I'd like to know how you (all) define success, in terms concrete enough for planning. I suspect "I'll know it when I see it" doesn't suffice. :) thanks, -C -- Craig Latta improvisational musical informaticist www.netjam.org Smalltalkers do: [:it | All with: Class, (And love: it)]

start script
by Norbert Hartl 07 Jul '07

07 Jul '07

Hi, I did a little start script for my spoon. It starts the memory image (spoon) and another squeak image to work with. I'll attach it just in case somebody is interested in. The archive contains three files: spoon.sh the start script bootstrap.sh is a symlink to spoon.sh bootstrap.st three lines bootstrapping the working image The script always starts the spoon image in the background and another image in the foreground. If you stop the fore- ground image the spoon image is also stopped. Invoked as bootstrap.sh the script invokes the bootstrap.st init script. This loads the naiad.st code and loads the naiad.pr project. The script is invoked as: - if you have both, a squeak 3.9 final image and the spoon installation in the current directory #> sh bootstrap.sh Squeak3.9-final-7067 If your spoon installation is somewhere else just give the path as a second argument to the script. Any feedback is welcomed. Norbert

Error opening browser
by Norbert Hartl 07 Jul '07

Hi, I'm one step further now. I just recognized that the memory.image opens another port at 7777 and that the lines in the naiad.pr are the ones I was looking for :) I can execute the first two commands in the naiad project. This establishesa connection between my squeak image and the spoon memory image. Invoking the third line I get the following: MessageNotUnderstood: Other>>module (proxy) Receiver: an Other Arguments and temporary variables: aMessage: module Receiver's instance variables: remoteIdentity: 65504896 session: an active instigating Wormhole OtherBrowser>>wormhole: Receiver: an OtherBrowser Arguments and temporary variables: aWormhole: an Other Receiver's instance variables: dependents: nil contents: nil currentCompiledMethod: nil contentsSymbol: nil systemOrganizer: ('Kernel-Chronology' ChronologyConstants Date DateAndTime Dura...etc... classOrganizer: nil metaClassOrganizer: nil systemCategoryListIndex: 0 classListIndex: 0 messageCategoryListIndex: 0 messageListIndex: 0 editSelection: #none metaClassIndicated: false selectedClass: nil module: nil wormhole: an Other OtherBrowser class>>newOnWormhole: Receiver: OtherBrowser Arguments and temporary variables: aWormhole: an Other Receiver's instance variables: superclass: Browser methodDict: a MethodDictionary(#addAllMethodsToCurrentChangeSet->a CompiledMeth...etc... format: 162 instanceVariables: #('selectedClass' 'module' 'wormhole') organization: ('accessing' contents contents:notifying: defaultBrowserTitle doI...etc... subclasses: nil name: #OtherBrowser classPool: nil sharedPools: nil environment: a SystemDictionary(lots of globals) category: #'Tools-Browser' traitComposition: nil localSelectors: nil OtherBrowser class>>openOnWormhole: Receiver: OtherBrowser Arguments and temporary variables: aWormhole: an Other br: nil Receiver's instance variables: superclass: Browser methodDict: a MethodDictionary(#addAllMethodsToCurrentChangeSet->a CompiledMeth...etc... format: 162 instanceVariables: #('selectedClass' 'module' 'wormhole') organization: ('accessing' contents contents:notifying: defaultBrowserTitle doI...etc... subclasses: nil name: #OtherBrowser classPool: nil sharedPools: nil environment: a SystemDictionary(lots of globals) category: #'Tools-Browser' traitComposition: nil localSelectors: nil --- The full stack --- (proxy) OtherBrowser>>wormhole: OtherBrowser class>>newOnWormhole: OtherBrowser class>>openOnWormhole:

How do I create a minimal memory?
by Trygve Reenskaug 06 Jul '07

06 Jul '07

Hi, I have just entered this list because I want to find out how I can use Spoon for my next BabyUML experiment. README: /Double-click the "spoon.bat" file. This will start the Spoon processor, which starts a local web server. /OK/ In the "naiad" folder are components for remote browsing and inspecting of the Spoon memory from a Squeak 3.9 system (they probably work with earlier systems as well). To use them, first start the Spoon system as described above. /OK /Then start the "naiad" application with the object memory of your choice. /Squeak3.9/naiad OK/ Then, file in "naiad.st", and load the "naiad.pr" project. /OK. Poject with violet playfield (nice :-) ) and a workspace. /"Hi; here are a few expressions to get you started with remote browsing." "Make sure you've filed in 'naiad.st' first." Smalltalk at: #ExampleWormholeServer put: (WormholeServer atPort: 9999). /Looks OK/ // / "/Make sure you've started the minimal memory first." ExampleWormholeServer connectToPort: 7777 atHostNamed: 'localhost'./ Fails. Executing the expression hangs with Wormhole>>peer being nil. The Spoon image is open in a window, but that window is empty and I cannot find any menus or command lines. *Perhaps I should start the /minimal memory/ first, but how?? * I'm not good at reading instructions, so I may have missed something. Any pointer will be welcome.
