2009-06-26Cleanup implemented for eclipse!Reinier Zwitserloot
There's one serious problem though: The cleanup routine modifies the eclipse internal AST, but doesn't update our bi-directional AST. Thus, or example, having a @Cleanup annotation inside the scope of another @Cleanup fails, because the application of the second one climbs up to the wrong block level (the original block level instead of newly built try block).

2009-06-25Removed adding the statement: 'final int PRIME = 31;' in the HandleData's ↵Reinier Zwitserloot
createHashCode method when there are 0 fields in the type (it would generate a local variable never used warning!)
2009-06-24javac's HandleData now generates the constructor only if it doesn't already ↵Reinier Zwitserloot
exist, and the staticConstructor is now also completed. Left: toString, hashCode, equals.
2009-06-24Added proper support for changing the AST as its being visited, both removal ↵Reinier Zwitserloot
and addition. The rule is now: children traversal traverses through the tree mostly as it was when it started.
2009-06-23fixed a bug where the auto-generated constructors (actual or static) would ↵Reinier Zwitserloot
throw eclipse errors if you had 0 non-static fields.
2009-06-23HandleData for eclipse now seems to work 100%. Also updated toString to use ↵Reinier Zwitserloot
deepToString, and added @Override in case people have warnings for missing @Override annotations on.
2009-06-23@Data's generation of the equals() method now works!Reinier Zwitserloot
2009-06-23Fixed some bugs in copyType(), and now the static constructor is generated ↵Reinier Zwitserloot
without any raw generics warnings - it is effectively done.
2009-06-23Figured out that our previous act of just assigning TypeReference objects ↵Reinier Zwitserloot
directly to other nodes (e.g. from a FieldDeclaration's type to a method argument) is NOT a good idea, as this screws up when the TypeReference object represents a generic type (like 'T') - each instance of a generic type has a different resolution, but 1 TypeReference object can only hold 1 resolution. Thus, a copyType() method has been written, and the Handle* classes have been updated to use it. Also, generateEquals() is half-finished in HandleData.
2009-06-23This is a 3-day bughunt that ended up being something extremely simple:Reinier Zwitserloot
** DO NOT REUSE TYPEREFERENCE OBJECTS ** because that makes the binding process go pearshaped - after hte first run, that TypeReference object's binding parameter is set, and as its set, the resolver won't bother re-resolving it. However, each parse run starts with new scope objects, and any 2 bindings created by different scopes aren't equal to each other. urrrrrrgh! Fortunately, a lot of code that 'fixed' methods by adding bindings and scope have all been removed, as the parser patch point is well before these bindings are created. Thus: ** NEVER CREATE YOUR OWN BINDINGS AND SCOPE OBJECTS ** because if it comes down to that, you're doing it entirely wrong. That's eclipse's job. We're patching where we are so you don't have to do this.
2009-06-23Put the actual numeric value of ASTNode.Bit24 in a comment, but it was ↵Reinier Zwitserloot
missing a 0!
2009-06-21More work on the HandleData annotation. Constructor seems to work fine, ↵Reinier Zwitserloot
static constructor not so much.
2009-06-21trivialReinier Zwitserloot
2009-06-21Due to a java bug, constants in enums don't work, so instead the default ↵Reinier Zwitserloot
access level for @Getter and @Setter have now just been hardcoded in GetterHandler and SetterHandler. Added ability to look up the Node object for any given AST object on Node itself, as you don't usually have the AST object. Added toString() method generating to @Data, and this required some fancy footwork in finding if we've already generated methods, and editing a generated method to fill in binding and type resolutions. HandleGetter and HandleSetter have been updated to use these features. Exceptions caused by lombok handlers show up in the eclipse error log, but now, if they are related to a CompilationUnit, also as a problem (error) on the CUD - those error log entries are easy to miss! Our ASTs can now be appended to. When you generate a new AST node, you should add it to the AST, obviously. Getter/Setter have been updated to use this.
2009-06-19Added initial support for the @Data annotation. Currently produces getters ↵Reinier Zwitserloot
and setters only, not yet a constructor, toString, hashCode, or equals. HandleGetter and HandleSetter have been updated to handle static (theoretic; you can't put annotations on static fields normally). You can now make AnnotationValue objects using just an annotationNode and a target type, as well as check if a given annotationNode is likely to represent a target annotation type. This is in Javac and Eclipse classes. HandleGetter and HandleSetter can now be asked to make a getter/setter, and will grab access level off of a Getter/Setter annotation, if present.
2009-06-18Created a fully working HandleSetter for eclipse, and refactored ↵Reinier Zwitserloot
HandleGetter a little mostly to stuff common code into PKG.
2009-06-18Expanded the AST printers to support a target PrintStream, and expanded the ↵Reinier Zwitserloot
@PrintAST annotation to let you supply an optional filename. Useful particularly for IDEs, which don't usually have a viewable console. Also renamed the printers to just 'Printer', as they are already inner classes of a specifically named type (JavacASTVisitor & co).
2009-06-17AnnotationHandlers can now return a boolean to set if they actually handled ↵Reinier Zwitserloot
the annotation or not (previously, the presumption was they always handled the annotation). This is very useful for PrintAST on eclipse, because before this change, you'd never see method contents (as the initial dietParse would come first). Now Eclipse PrintASTHandler will skip any non-full runs, and only print non-diet. It then returns true only if it printed.
2009-06-17Made the printing of Statements for @PrintAST slightly more useful (if a lot ↵Reinier Zwitserloot
more verbose), and bumped the version number in honour of quite a bit of redesign these past few commits.
2009-06-17A useful annotation that prints the AST of any annotated element via the ↵Reinier Zwitserloot
XASTPrinters in each ASTVisitor interface.
2009-06-17Moved the traverse() from Eclipse/JavacAST to Eclipse/JavacAST.Node, so that ↵Reinier Zwitserloot
you can start your traversal at any point, not just from the top. Also a bugfix for endVisitStatement which passed the wrong node, and method arguments in Javac are no longer misfiled as local declarations.
2009-06-17Renamed the Handler implementations.Reinier Zwitserloot
2009-06-17Turns out using instanceof checks to figure out if a LocalDeclaration is a ↵Reinier Zwitserloot
method argument or not (by instanceof checking if it's an Argument) is faulty, as e.g. the argument to a catch block is also an Argument object. Rewritten the visitChild method to be based on a switch on the Node's getKind(), just like JavacAST. This even looks nicer.
2009-06-17Massive refactors. This list isn't complete, but should give you an idea:Reinier Zwitserloot
A) many things in lombok.eclipse moved to lombok.core to enable reuse with lombok.javac. B) lombok.javac works now similarly to eclipse's model: We first make big ASTs that are bidirectionally traversable, then we walk through that for annotations. C) Instead of getting an annotation instance, you now get an object that is more flexible and can e.g. give you class values in an enum as a string instead of a Class object, which may fail if that class isn't on the classpath of lombok. D) sources to the internal sun classes for javac added to /contrib.
2009-06-16Implemented a lot of stuff for javac, but we ran into 2 major issues still ↵Reinier Zwitserloot
to be implemented: 1. The visit mode of a lombok handler (does not trigger off of annotations, instead sees every field, method, type, and statement), needs to be coded, 2. triggering off of annotations via APT's annotation handling system skips method-local classes. We'll need to recode this via an AST visitor like we need for issue #1 Other than that, triggering off of annotations works swimmingly!
2009-06-16Added ability to add visitor handlers.Reinier Zwitserloot
2009-06-15Propagated the fact that you get the Node object belonging to the ↵Reinier Zwitserloot
annotation, and not the field/type/local/method it goes with, all the way, so that you can easily generate a warning on an annotation in a handler.
2009-06-15Switched the level of the Node object you get during a visitAnnotationOnX ↵Reinier Zwitserloot
call from the Field/Type/Method/Local to the Annotation, so that you can interact with its handled flag.
2009-06-15Added annotations as definitive children of nodes in our custom AST, and ↵Reinier Zwitserloot
updated the visitor to call a separate visitAnnotationOnX method for annotated stuff. This way, 'handled' can be set per annotation. Also fixed a bug in AST generation that caused StackOverflowErrors on most source files, and did some cosmetic renaming of parameters.
2009-06-15all eclipse AST Statements objects are now part of the custom AST we build ↵Reinier Zwitserloot
for lombok. This way something like @AutoClose on a local var declaration can walk up one node, find all mentions of the variable, and add a close call right after the last mention.
2009-06-15Renamed lombok.transformations lombok.core as the purpose of this package is ↵Reinier Zwitserloot
to contain stuff that is useful for any lombok implementation (be it e.g. javac via apt or eclipse via agent), but not annotations and other classes that are for 'end users'.
2009-06-15Moved TypeResolver to the eclipse package, as it has eclipse-specific code ↵Reinier Zwitserloot
in it.
2009-06-14Made lombok more robust by catching exceptions near the top level and ↵Reinier Zwitserloot
turning them into eclipse-wide errors in the worst case, but usually in an error in the problems dialog.
2009-06-14Added support to generate errors, both on specific nodes in an AST ↵Reinier Zwitserloot
(generified code in HandlerLibrary for unintelligible annotation param values), and more severe general errors for eclipse's error log. Also unrolled the foreach loop on ServiceLoader, because any given .next() call can throw a ServiceLoaderError, which we now handle somewhat more nicely.
2009-06-12Error reporting now works - we can use the error reporting on decoding ↵Reinier Zwitserloot
annotation arguments for other places! Because this stuff works so well now, I bumped the version number as well.
2009-06-12Clinits should be skipped, as they are useless, and the docs even say they ↵Reinier Zwitserloot
will be skipped. Now they are skipped.
2009-06-12Whoops. Bugfix for enums. They get parsed correctly now!Reinier Zwitserloot
2009-06-12Now everything works; handlers are called via SPI, and annotations are being ↵Reinier Zwitserloot
parsed. w00t!
2009-06-12Removed the WeakHashMap for caching EclipseAST objects; obviously wasn't ↵Reinier Zwitserloot
working due to circular reference from the EclipseAST back to the CUD. Now, patched a field into CompilationUnitDeclaration and using that, which works much better together with the garbage collector.
2009-06-12Moved HandleGetter to its own package. This package should soon see ↵Reinier Zwitserloot
HandleSetter, HandleAutoClose, etc.
2009-06-12Singularly massive code change, too hard to document. Basically, hooking now ↵Reinier Zwitserloot
occurs in the two most sane places: - After the parser is done building a first rendition of the AST. (Usually lightweight and missing method bodies etc) - After the parser is done taking such a lightweight AST and filling in the gaps. Lombok then builts its own bidirectional and somewhat saner AST out of this, and hands this saner AST off for treatment. Things in the AST can be marked as 'handled'. This seems to work swimmingly and should allow us to easily identify the annotations that are for us, and work our magic, no matter where they appear or on what, including stuff inside method bodies.
2009-06-09Many changes:Reinier Zwitserloot
- Split off the actual agent work into a separate src package in preparation for creating separate jars. Involved a lot of renaming - Renamed TransformCompilationUnitDeclaration to TransformEclipseAST, as this class will also be transforming e.g. MethodDeclaration objects. - Expanded the patching to also patch in transform calls when the parser fills in the Statement array for existing constructors, methods, and initializers. - Redesigned the ClassLoaderWorkaround class quite a bit. - Positioning should not work correctly ('jump to method' should jump to the getter annotation). (Apparently, Clinit objects are always fully parsed in the original run, so no need to patch anything there).
