[Pharo-project] Aida with Realtime (WebSockets) support released
by Janko MivÅ¡ek Nov. 2, 2012

Nov. 2, 2012

Dear Smalltalkers, I think it can be safely claimed that Aida/Web is a first Smalltalk web framework, even more, one of the first frameworks at all to integrate HTML5 WebSockets for so called realtime web apps. Realtime in sense that values on the page are updated immediately when value changes on the server, without needing to manually reload a page. You can see that in action from WebSocket-capable browsers (latest Firefox and Chrome) if you open in two browsers the online Aida realtime counter demo, click buttons on one and observe changes instantly in both browsers: http://demo.aidaweb.si/demos?view=realtime And how easy is using real-time in your code? See the simplified code of above demo: WebDemoApp>>viewRealtime | e counterElement | self enableRealtime. counterElement := e add: self counterElement. (e addButtonText: ' Decrement ') noSubmit; onClickDo: [self observee decCounter]. (e addButtonText: ' Increment ') noSubmit; onClickDo: [self observee incCounter]. self observee onChangeDo: [counterElement update] on: counterElement app: self. self add: e. WebDemoApp>>counterElement | e | e := WebElement newSpan. e style: 'font-size: 40px'. e addText: self observee counter printString. ^e To describe this code a bit: you first enable realtime for this view of demo App. Element on the webpage to update in realtime must be created in a separate method (#counterElement). After buttons for increment and decrement we come to the main part - registering the block to execute on every change of domain object. Calling simply #update to the counter element is enough to be updated on all browsers which currently observe that counter demo. How this works? Behind the scenes a so called realtime channel is open between browser and Aida server. This WebSocket based channel is bidirectional and full-duplex, meaning that Aida can send back to the browser a message at any time. In above case a command to update the counter element is sent back to all browsers immediately after counter is changed. New Aida 6.5 Interim release is released for Squeak, Pharo and VisualWorks and available from usual places. See http://www.aidaweb.si for more. Everyone is welcome to try it and come with suggestions how to use this new feature, how to improve it, ....

[Pharo-project] wrong FileSystem paths resolving
by Pavel Krivanek Nov. 2, 2012

Nov. 2, 2012

Hi, in a Jenkins job configuration I have this bash line for Pharo start: ./vm.sh "images/$IMAGE_NAME.image" "$WORKSPACE/support/pharo.tank" "$WORKSPACE/support/pharo.tankst" In the console I got this error + ./vm.sh images/PharoKernelTanker-2.0.image '/builds/jenkins/workspace/Pharo Kernel 2.0 Reload by Fuel/support/pharo.tank' '/builds/jenkins/workspace/Pharo Kernel 2.0 Reload by Fuel/support/pharo.tankst' ==== Startup Error: FileDoesNotExist: file:///builds/jenkins/workspace/Pharo Kernel 2.0 Reload by Fuel/images/Fuel/support/pharo.tank As you may see, the image argument is passed by full path but it is interpreted wrongly. Tanker uses simply 'xxx' asFileReference on argument. The problem is clearly in the spaces in the path (see "Fuel/support/pharo.tank" at the end of path). On my localmachine id fails too if I use "$PWD/pharo.tank" "$PWD/pharo.tankst" as argument and the path does contain spaces. When I have this files in the image directory (even when the image path contains spaces) and I use only names of this files without full path, they are loaded well. Cheers, -- Pavel

[Pharo-project] differently organized method categories in the Debugger dnu: create process
by Paul DeBruicker Nov. 1, 2012

Nov. 1, 2012

Hi- When I create methods using the Debugger's 'Create' button I am never sure which categories are used in the class I'm adding the method to versus those in its super classes. In an effort to not have to think about that any more I've adapted the ClassDescription>>#allMethodCategoriesIntegratedThrough: to put the method categories that are used in the target class first, then those in the super classes after that. I think this should work in Pharo and Squeak but I've only tested it in Pharo 1.4. I've attached a changeset and also pasted the method below Paul allMethodCategoriesIntegratedThrough: mostGenericClass "Answer a list of all the method categories of the receiver and all its superclasses, up through mostGenericClass" | otherClassCategories thisClassCategories combinedClassCategories | otherClassCategories := OrderedCollection new. self allSuperclasses do: [ :aClass | (aClass includesBehavior: mostGenericClass) ifTrue: [ otherClassCategories addAll: aClass organization categories ] ]. otherClassCategories remove: 'no messages' asSymbol ifAbsent: [ ]. thisClassCategories := self organization categories asSortedCollection: [ :a :b | a asLowercase < b asLowercase ]. ^ Array streamContents: [ :stream | stream nextPutAll: thisClassCategories; nextPutAll: ((otherClassCategories asSet removeAllSuchThat: [ :each | thisClassCategories includes: each ]) asSortedCollection: [ :a :b | a asLowercase < b asLowercase ]) ]

Hi Right now if I want to get the separator I have to get the FileSystem instance FileSystem disk separator I was thinking that it would be good to be able to access separator without going to the instance. Does it make sense? Probably not since the separator depends on the store used and so separator would have to delegate anyway. Stef
