I've just shadowpasted a first cut at the new doit() method
<http://scsys.co.uk:8002/416488>, as discussed in this group, so that
those interested can look it over. You'll have to hunt for it in the
file a bit -- the actual method is buried deep in a test program.
I settled on doit() as the name. process() was the best alternative,
but 'process' is just a Latin-ism for 'doit'. In this first cut, doit()
is in the 'main' namespace -- when finished it will be a
Marpa::R2::Scanless::R method.
doit() reads an input and on success returns a ref to the only parse.
On any kind of failure, it throws an exception. Very importantly,
ambiguity (more than one parse) is considered an error, and reported as
such. Also, if any events cause the read to terminate prematurely, an
error is thrown.
The intent is that this is a very simple method, good for beginners and
for a first cut, and uncomplicated by options. If you want events, or
want to treat an ambiguous parse as anything but an error, or want fine
control of the errors, you should use the read() and value() calls directly.
Thanks, jeffrey
