Annotations

[Rich Hickey]

I've started adding some support for Java annotations, as of this
commit:

http://github.com/richhickey/clojure/commit/fa899d22dceb531d9f5af833ac6af0d956e6bdc7

Example of use:

http://gist.github.com/377213

It supports annotations for definterface/type/record types (put in
metadata on type name), deftype/record fields (in metadata on field
names), and deftype/record methods (in metadata on method name)

Interestingly, the bulk of the work is only 50 lines of Clojure. The
same code should be useful to gen-class.

Feedback welcome,

Rich

Yay !
Do you also intend to add indentation support for method args ? Seems
to be heavily used e.g. in annotations for web services when one wants
to map methods args names to request args, etc. ?

Fantastic! I'm just about to do some JAX-WS stuff (which requires
annotations), so this is a welcome change.

The syntax looks no worse than Java's, so no comment on that...

Looks nice from just looking at the gists - I have a small project
where annotations support would actually come in handy as well so will
definitely give this a try shortly.

Thank you very much for this new feature. I was able to use it
successfully to create and test a simple EJB. I wrote about this on my
blog and put a demo up on GitHub.

Blog entry:

GitHub link:

I have not tried anything in a real application, but it seems to work
quite well.

Thanks again.

Sincerely,

Daniel Solano Gómez

Neato! I've been hoping for this - thanks :)
