I've developed a grammar (with help from various people of course) for
quoted strings: http://scsys.co.uk:8002/424926
Requirements:
o Strings must be quoted
o Strings are either single or double quoted
o The escape character is \
o If the string is single quoted, internal single quotes must
I've posted some things previously on this topic - but in short, you don't
really need to use events to do this. It's possible to do it in a
semi-straightforward fashion without a lot of jumping through hoops (just a
bunch of rules).
Here's some grammar fragments demonstrating what I'm talking
Thanx for the link.
I did not consider that case, since I'm really interested in the Graphviz
DOT file format, where quotes if any must be double quotes, and internal
quotes must be escaped.
However, I will examine the code you link to, since ever such example is

I think I'll release such samples (I have encountered a few) as
MarpaX::Demo::SampleGrammars. It'll be basically a dummy module with the
good stuff in scripts/*.pl.

2 of those 3 samples (the 2nd 3rd) produce ambiguous parses. Is that
what you find too?
Yes, the code warns about it; actually I was planning to deal with it as
part of my current work on ASF-based
