@amelentev I've almost got Java 11 working. There's been some changes to operator resolution that I haven't finished working out, but the JPMS has not been a showstopper. There's a scary warning WARNING: An illegal reflective access operation has occurred...WARNING: All illegal access operations will be denied in a future release but it works for now.

I've been wanting to dig into java compiler hacks for a while, and it's been fun. I was wondering if you could share some motivations for the current implementation. Is there any way to achieve all this without subclassing? Do you know how Lombok handles things? The current mechanism doesn't use annotation processing or rounds. Do you know where that's explained in more detail? Is it possible to "undo" detection of compiler errors?

amelentev commented 4 years ago

Great news! You can read about implementation details in my paper https://github.com/amelentev/java-oo/raw/master/doc/ijpla.pdf As of jdk8, there was no way to do it without subclassing. Lombok used similar hacks and more bytecode patching back then. I don't know the situation now. I don't know how to "undo" errors on javac, but the current java-oo plugin for Eclipse does that for Eclipse ecj compiler.

After installing eclipse extension plugin, it still only works on JDK 8 and does not work for JDK 9 or later. Any fixes?

rsmckinney commented 3 years ago

Note, the Manifold project provides a similar feature for operator overloading and works with Java 11+ and the latest IntelliJ and Android Studio releases.

catchex commented 3 years ago

@rsmckinney Manifold can be divided into two versions, one for free and one for charge

rsmckinney commented 3 years ago

@catchex Manifold is free. Contact info@manifold.systems or visit the Slack group for more info.

@rsmckinney ObjectiveSQL needs operator overloading to solve SQL expression calculation, so I want to get some solutions for Java operator overloading in compiling and coding.

javaNoviceProgrammer commented 3 years ago

I managed to get this amazing plugin working on Eclipse-2020-12 with JDK 15. Basically, the Scala IDE was causing problems, so in order to get JDT weaving I installed AspectJ development plugin first and then the java-oo plugin. Works like a charm. Please update the guide so that people don't install Scala IDE anymore. Thanks.

@rsmckinney Unfortunately manifold has no plugin for eclipse. Which is very sad.
