[Pharo-project] AST-Navigation short demo
by Gisela Decuzzi May 9, 2013

May 9, 2013

Hi! I've recorded the video as Damian suggested to show how to use the code navigation based in the ast :) Here it's the video: http://www.youtube.com/watch?v=pFLyzEI0jmE (Sorry for my English) And if you want to try: Gofer it url: 'http://smalltalkhub.com/mc/gisela/NodeNavigation/main'; package: 'ConfigurationOfNodeNavigation'; load. ((Smalltalk globals at: #ConfigurationOfNodeNavigation) project version: #development) load. A summary for the shortcuts: - going to the parent: ctrl + shift + p (command + shift + p for mac) - going to the first child: ctrl + shift + o (command + shift + o for mac) - going to same level node: ctrl + shift + u (command + shift + u for mac) It would be great to use the arrowUp or down, I want to check if it's easy to make them work first and also make the navigation available for debugger, workspace, message browser (...)

[Pharo-project] XPath issue ?
by Herve Verjus May 9, 2013

May 9, 2013

Dear All, I try a very simple example: mydoc.xml document: <?xml version="1.0" encoding="UTF-8" ?> <first> <second> <item type="attvalue">nodevalue</item> </second> </first> And the Pharo code found in the book.pharo-project.org: | doc results | doc := XMLDOMParser parseFileNamed: 'mydoc.xml'. results := ( XPath for: 'first' ) in: doc. results explore As a result, I obtain an empty OrderedCollection...It should contain an element. Then a make some changes using different XPath expressions (i.e. '/first/second/item/@type", etc.) but no way. Then I discover the first element of the XPath expression must not be the root of the XML doc. If I change the mydoc.xml, introducing a new root element: <?xml version="1.0" encoding="UTF-8" ?> <foo> <first> <second> <item type="attvalue">nodevalue</item> </second> </first> </foo> Everything is ok (the same code as above). Here, XPath assumes that the first tag we are looking for is not the root of the doc, otherwise it fails. I'm not so sure but it seems that such implementation doesn't follow the XPath specs. I tried another example from http://www.w3schools.com/xpath/xpath_syntax.asp and same results: I obtain an empty collection when using an XPath expression beginning with the 'bookstore' tag, the root element of the doc: | doc results | doc := XMLDOMParser parseFileNamed: 'books.xml'. results := ( XPath for: '/bookstore' ) in: doc. results explore Maybe, I missed something... Note: I have had to replace the isTag (deprecated) with isElement in some piece of XPath code. Cheers, Herve

[Pharo-project] Understanding NBOpengl
by dimitris chloupis May 8, 2013

May 8, 2013

Ok so I tried to learn Opengl ES 2 (and opengl 4) during my eastern vacations because I realised that I dont really need Athens or vector graphics for my GUI , since I will be dealing mostly with 3d graphics anyway. (My project "ephestos" will be an effort of creating a 3d app for pharo, see also "blender") So when I tried to run the demos i get an error with NBMacGLContextDriver>>supportsCurrentPlatform Â Â Â "obviously, for Mac intel-32 only :)" Â Â Â ^ NativeBoost platformId = NativeBoostConstants mac32PlaformId My mac is "obviously" not 32-bit but 64 bit, but I dont know if that matters since pharo is only 32 bit anyway. The bug is also obvious it should be mac32PlatformId and not mac32PlaformId. I correct and proceed and gives me a new error this time in NBMacGlApi>>glApiCall: fnSpec index: fnIndex attributes: attributes context: contextToRetry Â Â Â ^[ Â Â Â Â Â Â (NBCallFailureHandler for: contextToRetry) retryWith: [ :targetClass :targetMethod | Â Â Â Â Â Â Â Â Â (NBFFICallout Â Â Â Â Â Â Â Â Â Â Â Â targetClass: targetClass targetMethod: targetMethod fnSpec: fnSpec) Â Â Â Â Â Â Â Â Â Â Â Â stdcall; Â Â Â Â Â Â Â Â Â Â Â Â generate: [ :gen | self emitCall: fnIndex generator: gen ] Â Â Â Â Â Â ] Â Â Â ] on: NBNativeCodeError do: [:err :handler | Â Â Â Â Â Â err errorCode = ErrorFnNotAvailable ifTrue: [ Â Â Â Â Â Â Â Â Â "Native code is installed, but function pointer not loaded yet. Â Â Â Â Â Â Â Â Â Try to load function and retry the call"Â Â Â Â Â Â Â Â Â Â Â Â (self tryGetFunctionPointer: (self class glFunctions at: fnIndex)) ifFalse: [ ^ err pass ]. Â Â Â Â Â Â Â Â Â ^ handler retrySend Â Â Â Â Â Â Â Â Â ]. Â Â Â Â Â Â err passÂ Â Â Â Â Â Â Â Â ] The problem here that NBCallFailureHandler is nowhere to be found. At first I though my NB was lagging behind in version so I download from smalltalk Hub and did ConfigurationOfNativeboost loadStable. it updated without errors but still that class is nowhere to be found. So my question is this, does it really worth it to struggle with NBOpengl or will it better to learn how Nativeboost works and use Opengl myself ?
