| Re: [aspectj-dev] ajc AST Documentation |
The place this is meant to be is on the eclipse wiki for extending AJ/AJDT: http://wiki.eclipse.org/index.php/Developer%27s_guide_to_building_tools_on_top_of_AJDT_and_AspectJ But there isn't a whole lot there and it is a little out of date, so also see these bugs: https://bugs.eclipse.org/bugs/show_bug.cgi?id=110465 https://bugs.eclipse.org/bugs/show_bug.cgi?id=211201 The AST support is far from complete and traditionally the users provide patches back that augment what we have with what they need and I commit them. > 1) The framework, which I'm extending is using the ASTNode and ASTVisitor > from the package org.aspectj.org.eclipse.jdt.internal.compiler in > project org.eclipse.jdt.core to build a graph. However, the ASTNode > class in that package does not provide a way to get the underlying > AST. So how can I make some modifications on it like described in the > article in Reference [1]? See the bug reports on creating AjASTVisitors - best place to find what does and doesn't work is look at the test cases you can reach them by browsing cvs http://dev.eclipse.org/viewcvs/index.cgi/org.aspectj/modules/org.aspectj.ajdt.core/testsrc/org/aspectj/tools/ajc/ASTVisitorTest.java?root=Tools_Project&view=markup http://dev.eclipse.org/viewcvs/index.cgi/org.aspectj/modules/org.aspectj.ajdt.core/testsrc/org/aspectj/tools/ajc/?root=Tools_Project > 2) Can I modify an AST and then directly let ajc "compile" that > modified AST?

All I have is what is above, I don't do much with the AST and as I say, I rely on contributions from people using it to extend it. Andy.
