Issue 484 in moose-technology: PetitParser debugger does not show nesting anymore
by moose-technology＠googlecode.com 17 Nov '10

Status: New Owner: ---- Labels: Type-Defect Priority-Medium Component-PetitParser Milestone-4.2 New issue 484 by tudor.girba: PetitParser debugger does not show nesting anymore http://code.google.com/p/moose-technology/issues/detail?id=484 PetitParser-lr.206 replaces the usage of def: in CompositeParser to make instantiation faster. However, this change makes the Debugger from the PetitGUI to not show the tree anymore.

The future of Opax in XML-Support
by jaayer 17 Nov '10

17 Nov '10

The most recent version of XML-Support comes with a factory-based abstraction layer to customize the node object construction done by the parser. The default factory is just a number of stateless accessors with names like #elementClass and #documentClass that return class objects. This class can be subclassed and those messages overridden, and the subclass can then be instantiated and injected into a DOM parser using #nodeFactory: before parsing. However, also included is a node factory subclass named XMLPluggableElementFactory that can map specific elements to specific element classes based on the name and namespace information of the elements in question. Here is an example of its use: doc := (XMLDOMParser on: aStringOrStream) nodeFactory: (XMLPluggableElementFactory new handleElement: 'user' withClass: MyUserElement; handleElement: 'report' withClass: MyReportElement; handleElement: 'report' namespaceURI: 'urn:specialReport' withClass: MySpecialReportElement); parseDocument. This is undoubtedly similar to Opax, if not in its approach then certainly in its intent. I feel, however, that it is superior to Opax in a number of respects and question whether Opax should remain in XML-Support. First, the node factory abstraction layer is based on the DOM parser and XMLNode classes, not the SAX parser and the custom OP*Element classes Opax has added. This means that users will get back instances of XMLElement subclasses rather than OPGenericElement subclasses, and those objects will support the entire XMLElement protocol. Second, the pluggable element factory enables more powerful element/class mapping based not only on the names of elements but their namespace information as well. Third, the element factory and its test are both quite small, in part because they do not need to duplicate the functionality of XMLElement like OPGenericElement does. Fourth, because the element factory is a subclass of XMLNodeFacory, it can be subclassed further to exert additional control over which classes the DOM parser should use for other, non-element nodes. Fifth and perhaps most important of all, the factory approach does not require a specific subclass of XMLDOMParser to be used; it is injected into a DOM parser by the user, so any DOM parser, even ones that already exist, can use it without modification. To use Opax, however, a parser must be a subclass of OPOpaxHandler, which is itself a subclass of SAXHandler. That means DOM parsers can't be used with Opax at all, and existing SAX parsers can't use it unless they are rewritten to be subclasses of OPOpaxHandler. I think Opax should be taken out and made optionally loadable by the Metacello configuration file. In fact, this should be done regardless of which approach is preferred, as the package is already quite large and stands to get larger as more is added. I plan on making XMLWriter a separate but required package, and the test suites separate but optional packages. If anyone has any objections, I would like to hear them.

This is why you can get a little explanation beside the acronym Do you prefer Moose or SotwareAnalysisPlatform Glamour or BrowserFlowFramework Pier or SeasideAppllicationCMS Seaside or dynamicWebFramework Citizen or the fuckingLibToParseBibUglyEntries.... Mondrian or theDrawingAPIToOnlyDrawBoxesAndArrows I prefer the first. So let us be a bit clever. Have nice name and explanation. look at VW they have VisualWorks Web Server.... I proposed them to call it Sioux long time ago (because of blackfoot (smart guys), Apache, ....).

why? a name is not an explanation. Ava: an XML parser So for me I repeat is XML support is a bad name. Look at Comanche, Apache why apache is not called HTTPServer? Stef >> We can always change it back to YAXO or change it to something else entirely. I would at least prefer something with "XML" in it so people will still be able to easily find, whether through Googling or searching on SqueakSource, an XML parser for Squeak/Pharo/Gemstone without having to know the cutesy name its developers chose for it ahead of time (see practically any Ruby library for an example of what I'm talking about). > > > Yep.

I don't really know. this is why I propose that we think about it, have fun and get a real cool name. For example (this is not really working) just brainstorming 3 seconds. AvaDoom (because Ava Gardner ~ Gardener ~ Trees of Dom Objects) the logo could be a voodoo invocation. Stef
