Hi,
At this year's ParGram meeting, we decided we should have 2 meetings in
2014 (spring and fall).
Regarding the spring meeting, Ron Kaplan has volunteered to host it at
Nuance in California. To find a suitable date, I created a Doodle poll
which you can find here:
http://doodle.com/niwz4hgptcn3rpsr
Please participate in the poll so that we can find a date that suits
most of us. By the way: This will be a special occasion since we will be
celebrating 20 years of ParGram!
Cheers,
Jani

Hi,
I have a question about the scope of two specific operators in XLE:
shuffle and Kleene closure.
Say I have an expression like the following:
XP --> X*
,
Y.
Depending on how the scope of the operators is interpreted, my guess is
that there are different types of possible behavior:
1) XLE interprets the expression as [X,Y]*. XLE will accept strings of
the following type:
XY
YX
XYXY
XYYX
2) XLE interprets the expression as [X]*,Y. XLE will accept strings of
the following type:
XY
XXY
YX
YXXX
(Only a single Y in each string.)
The XLE documentation states that if two operators (* + # ~ - \ / , < >)
occur next to each other, it disambiguates possible ambiguities by
giving the left-hand operator wider scope than the right-hand operator
(if I am not mistaken, this is behavior 1).
My questions are these:
- Is there scope ambiguity in my expression?
- If there is scope ambiguity in my expression, how do you suggest it be
resolved towards behavior 2 (which is the behavior I want)?
I have implemented my expression in XLE, and the behavior is the desired
one, but I'd like to understand why.
Thanks,
Jani
