Hi, I've just finished writing the main interfaces/classes of the new rendering mechanism (see http://dev.xwiki.org/xwiki/bin/view/Design/NewRenderingArchitecture) . At this stage I'm eager to get feedback from the community. Here's a quick explanation of how it works: Main interfaces: * Parser: String getSyntaxId(); Document parse(Reader source) throws ParseException; * Listener: void beginBold(); void endBold(); void beginItalic(); void endItalic(); void beginParagraph(); void endParagraph(); void beginList(ListType listType); void endList(ListType listType); void beginListItem(); void endListItem(); void beginSection(SectionLevel level); void endSection(SectionLevel level); void beginXMLElement(String name, Map<String, String> attributes); void endXMLElement(String name, Map<String, String> attributes); void onLineBreak(); void onLink(String text); void onMacro(String name, Map<String, String> parameters, String content); void onWord(String word); void onSpace(); void onSpecialSymbol(SpecialSymbol symbol); * Document: top level element for the AST representing a document in memory. All elements below are Block(s) * Macro: execution of MacroBlock(s) int getPriority(); List<Block> execute(Map<String, String> parameters, String content, final Document document) throws MacroExecutionException; * MacroFactory: Macro getMacro(String macroName, Syntax syntax) throws MacroNotFoundException; * Transformation: ability to make transformation on the AST int getPriority(); void transform(Document document, Syntax syntax) throws TransformationException; Here's some pseudo code that shows the whole process: Parser parser = componentManager.lookup(Parser.ROLE, "xwiki/2.0"); Document document = parser.parse(sourceReader); TransformationManager txManager = componentManager.lookup(TransformationManager.ROLE); txManager.performTransformations(document, new Syntax(SyntaxType.XWIKI, "2.0")); XHTMLRenderer renderer = new XHTMLRenderer(writer); document.traverse(renderer); Existing implementations: ========================= * DefaultMacroFactory * XHTMLMacro * XHTMLRenderer (Renderer = Listener) * XWikiSyntaxRenderer * DefaultTransformationManager * MacroTransformation (to execute Macros in the right priority) * DoxiaConfluenceParser * WikiModelXWikiParser Next immediate steps: ===================== * introduce cache component (in a separate module) for caching the AST * add syntax metadata to current Document class * Implement following macros: - TOC Macro - Include Macro - Velocity Macro - Groovy Macro * Continue Doxia bridge * Continue listener event implementation (there are some missing) * Continue Confluence to XWiki conversion Feedback most welcome.
