Re: [cme-users] Syntax Error

Hi Juri,

Wow, this is an interesting one!  I'll
have a look as soon as the Eclipse.org webmaster resets my password so
that I can actually get into the CVS repository and recreate my workspace.
 (Don't ask--disaster with the help desk).

Just FYI, the underlying problem is
very likely due to the fact that we're stressing our current parser generator
beyond its intended limits, and I'm guessing that it treated your syntactically
erroneous tokens as identifiers instead of keywords, and then somehow came
up with some interpretation that made sense (though clearly not what you
intended).  I am in the process of changing us over to a different
one, which will address most of this class of problems.  (In other
words, I will look as soon as I can, but if it's what I suspect it is,
I won't be able to do much about it until I finish the migration.)

Subject	[cme-users] Syntax Error

Hi,

just a question... I had quite a few Syntax Errors when I messed up the
structure of a query, but none of the following queries raised such a
signal


enclosingType(call( * Cosmos.execute(..)))
EnclosingType(call( * Cosmos.execute(..)))
enlcosingType(call( * Cosmos.execute(..)))
...

You get the idea.

The queries returned no results, as we all knew they would... but they
also didn't raise an error because the construct "enclosingType"
in all
its permutations is not known...
I would have expected someone telling me that I am using a vocabulary
that does not exist. ;-)


                
Juri
