Re: [aspectj-dev] Fwd: metacomments and aspectj

Hi Sergev/Andrew and others.

I think what you are trying to do would be possible with abc (the
AspectBench Compiler), however, it may be overkill. A simple parser
should do, actually. Both ajc and abc are designed to implement
joinpoints that are dynamic, i.e. execute at runtime of the program.
What Sergev is trying to do is matching purely static entities
(comments) and actually printing them *at compile time*. This does not
have much to do with AOP. I would suggest to use a simple SableCC or
JavaCC parser. You could use a simple visitor to print the comments.

Another alternative could even be to use awk, grep and/or sed.
