[rules-dev] Syntax diagrams available on my home page

[Wolfgang Laun]

I finally found another program (PeterThiemann's Ebnf2ps) for creating
syntax diagrams from an EBNF grammar which is close to, but regrettably not
identical to the antlr3 grammar notation. Babel all over again.

You can download them as a pdf file from my home page
http://members.inode.at/w.laun/ or just follow this
link<http://members.inode.at/w.laun/drools/DroolsSyntax.pdf>.
The grammar has been streamlined according to what was discussed here
yesterday.

Currently they are copyright Wolfgang Laun, which doesn't mean I won't
contribute them to the Project. But the Team will have to make up their mind
whether they want them at all, and in which way, and whether they want to
include the production steps, etc. etc. Currently I run Ebnf2ps (a Haskell
program) to produce the diagrams as individual eps files, which are imported
by a simple LaTeX document. Some NTs had to be broken down so as not to
exceed the margins because this (otherwise fine) program doesn't have a
feature to wrap wide diagrams. If I get around to learning my umpteenth
programming language I might have a go trying to fix that...
