RE: [aspectj-users] AspectJ + Groovy?

["Ron Bodkin" <rbodkin@xxxxxxxxxxxxxx>]

Hi Jim,

I used AspectJ with Groovy for unit testing about 6 months ago and generally
was able to get aspects to apply to compiled Groovy code, and the Groovy
code could call on ITD's. I don't believe there was a way to implement
aspects in Groovy, and trying to weave into interpreted Groovy seemed to be
challenging (I think you'd have to weave the Groovy library and then you'd
have something like trying to weave into reflective calls in Java).

Sam Pullara also wrote a nice blog entry on an interesting use case for
combining AspectJ with Groovy for coverage tracking:
http://homepage.mac.com/spullara/rants/C1464297901/E158600668/

I think it would be great to have AOP support for Groovy, but my $.02 is
that the right level to work at is the Groovy language level, not in the
underlying compiled Java code. In particular, I think you'd want to have
pointcuts that work well for closures and dynamically defined methods. There
have been "pointcuts"(*) defined in AspectWerkz and JBoss AOP that do
something similar, like hasfield and hasmethod. In Groovy, it would be
really natural to match instances that have a given method or field...

(*) I don't think hasfield/hasmethod should be defined as pointcuts since it
breaks orthogonality. Instead, these ought to be type patterns, just like
Foo+ or annotation matching for type patterns.

Subject: [aspectj-users] AspectJ + Groovy?

Hello All,
I'm just wondering if anyone has tried to use AspectJ and Groovy together in
any sort of combination.  I'm sure it's possible, but mostly I'd like to
start a discussion both on how the two can be used together.  Additionally,
maybe we can start a set (or subset) of documentation for the AspectJ docs
on the topic too.

A few discussion topics to consider (this list is by no means exhaustive):
1.How to write aspects in Groovy
2. How to attach aspects to Groovy code
3. The possibility of the AspctJ toolkit and AJDT supporting Groovy 4. The
possible uses / advantages the two working together might have over
traditional Java + AspectJ development

If any of these topics should be moved to the aspectj-dev mailing list,
please don't hesitate to move them there.

Cheers,
Jim

P.S. Although I've been following the AspectJ mailing lists for a while, I
think I'd like to get involved now, most likely with documentation.  Any
guidance would be helpful in this matter too.  You can just email me
directly about that if you'd like.  Thanks! :-)
