Where has the OnTheFlyCompiler gone? [message #761406]

Hi,

Up to Xtext 2.1.1 I have used the OnTheFlyCompiler to compile my
expressions into Java byte code - In the 2.2 nightly build, this class
does not exist anymore :-( Has this feature been abandoned or has it
just been moved somewhere else and I am too stupid to find it?

Thanks,
Kai

I don't even see it in Xtext 2.1.1 - in which plugin should it live (so I can check against my zillion Xtext installations)?

Sorry, I should have mentioned that it was part of the Xbase plugin, see
http://git.eclipse.org/c/tmf/org.eclipse.xtext.git/tree/plugins/org.eclipse.xtext.xbase/src/org/eclipse/xtext/xbase/compiler/OnTheFlyJavaCompiler.java?h=2.1.x_Maintenance

Hi Kai,

we had to move it to the test bundle since it introduced unwanted
dependencies.
So yes, the feature was removed from xbase core.

Hi

Sounds like an interesting functionality. Is it possible to package it
in its own feature so that it can be ignored when the dependencies are
unacceptable but used when required. Seems like I might like to use it
for OCL 2 Java.

It would have been nice if that had been mentioned on the bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=354635, which I just
wanted to verify. Very sad to hear, that this feature is not supported
any longer - I quite liked the possibility to directly produce compiled
bytecode for performance reasons...

So I would agree with Ed: It would be nice if that feature could be
moved into a separate bundle to avoid any unwanted dependencies on the
xbase core bundle.

Cheers,
Kai

Hi Kai,

I'm sorry about that one. The ticket about the unwanted deps was another
one. Please file a feature request for the compiler. We may want to
reinstantiate it in the xbase.ui plugin which would allow the necessary
deps.

Regards,
Sebastian

Done: https://bugs.eclipse.org/bugs/show_bug.cgi?id=365870

I do not think that that would be the right place for it - the feature
is mainly required on a runtime and for performance optimization; it is
therefore probably quite likely that the xbase.ui plugin is not even
present.

Indeed. If I can use it for OCL 2 Java, I may not really want xbase at
all, certainly not xbase.ui.

Perhaps this could be a contribution to something more like emf.codegen.
