Ed Merks,

Just wanted to thank you for the JET Editor you created. I've been using it for a couple weeks now, and it's a huge help!

You're welcome, and hank you for saying thank you. One never knows what people actually use, at least until they complain about it. So it's very refreshing to get a thank you instead of a complaint.

It must have been pretty complex to implement this JETEditor. Nice work.

One bit of feedback. After I've opened and closed a number of .javajet files, the JETEditor stops accepting input and won't open new files. The only way I've found to get it to work again is by restarting my Eclipse workspace. But at that point Eclipse won't close using Exit or Restart, so I need to kill the Eclipse process manually. No error message, but here's what I see in the log file:

I can't reproduce that but I opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=558657 and committed a fix (more of a hack really) to prevent such an overflow. You can update to this build and see if that addresses the problem:

http://download.eclipse.org/modeling/emf/emf/builds/nightly/latest

And yes, this was super complex to implement. The code that's overflowing is there because the JET editor edits multiple documents (because it must support JET includes which can even include the same template more than once, each of which is in a different context where the variables in the Java code could resolve to different variables declared in that context) and hence there are multiple editor inputs involved. The context menu must of course be for the document/editor input of the current document which might well be different from the editor input (root template) of the overall editor. The Eclipse frameworks are not well designed to support this use case, and we must leverage the Java Editor which is most certainly not designed for such a use case.

If you experience other problems, please open a Bugzilla, ideally with a sample (or steps) that reproduces it.

It's in the most recent release. It will be available in you have the EMF Code Generation UI feature installed (or something that includes it such as the EMF SDK). Quite shockingly, I even wrote documentation:

Hi

It's in org.eclipse.emf.codegen.ui which can be installed from "2019-12 - http://download.eclipse.org/releases/2019-12" after unchecking "Group items by category".

But if you've already installed the EMF SDK, you should already have the JET editor.

Open With... any file and search down the Other... editors; JET Editor should be there.
