Hi Mark,
Regarding your introspection utility:
It looks like this utility is unable to parse the pattern syntax of a rule LHS
(Left Hand Side). I suspect it may not be able to parse anything that doesn't
look syntactically like lisp: is this correct?
Fortunately, you may only be missing a few operators to make your parser more
complete:
The boolean operators " & | ~ ", functions and their place holder " : "
(See "JESS Language" Chapter 2 Basic Patterns for an explanation of what
you colorfully describe as 'cartoon swearing'!)
As I mentioned I'm not a lisp programmer, so I don't know exactly what's
missing.
Hope you do pick it up again, though - performing introspection on rule
meta-data could really help those of us with substantial rule sets. But be
cautioned that this method will be limited to clips source code for fact
assertion sources (facts can potentially be generated from java objects as
well).
If you do any more with this utility, let us know.
Thanks,
Jack
