Re: [Exp-engine-devel] Trying to load on recent sbcl on Mac or Linux

Yes, use the function EE:EXP-ENGINE.

You can build the standalone executable if you modify the
"sbcl/deliver.lisp" file to load "load-engine.lisp" instead of
"system.lisp".

Express Engine is currently in a development state.  Not all of the
functionality is even working right now.

What are you wanting to do with it?


Hi Craig,

Dave was writing on my behalf, so let me explain.

One of my products is a STEP preprocessor.  To date, it has always written
AP203 files.  I have recently gotten an AP214 version working as well.  In
both cases I've used the steptools.com online AP203/AP214 validater
extensively during development to help make sure I was writing valid files.

One of my short term goals is also to support AP242 export.  But the
steptools online tools cannot validate AP242 files.  And of course, for
automatic testing purposes it would be terrific to have a command-line tool
for validating AP203 and AP214 too.

I've tried STEPcode.  Their tools compiled with only very minor glitches
and will quickly check a file to make sure it's well-formed.  But they
cannot check RULEs.

I've toyed a little bit with coding my own solution, but I'm having some
issues getting the pseudo-BNF grammar (WSN, I guess) for schemas to
actually parse a full schema file -- and even when I get that working, I'd
obviously have to implement the actual functionality for the Express
language, which is pretty daunting.

Express Engine's --validate option is exactly what I need, I think.  But my
attempts to get it running had multiple failures.  (Including trying the
binary Windows versions -- I never managed to get them to do more than
print out the command line options.)  So I asked Dave Cooper if he could
figure it out -- he is a customer of mine and a heavy Lisp user.  And here
we are.

What can I do to help get the command line version of Express Engine
working again?

Thanks,
Sol
