Good evening Clint, Congratulations on your move. I hope the weather is more clement.
The problem that arises with using IYACC and IBPAG2 is that I want to be able to define new operators (deinitely) and possibly new constructs at runtime. This is why I am looking at Katadhin and PEGs. One of the reasons I want to convert Katadhin to something like Icon/Unicon is to get away from the base structure of C#. IYACC and IBPAG2 seem a tad difficult to run at runtime to extend the runtime recognition of new operators etc. If there are any references to materials that have looked at this area for LALR or LR parsers, I am willing to spend some time reading them. I have already spent time over a number of years trying to work out how to extend the grammar recognised by a LR parser at runtime to not much avail. I do not have concentrated amounts of time to devote to the subject. I am nearing the end of my 5th decayed. There are far more important things to occupy myself with - my wife, my children, my grandchildren and my brethren in our little fellowship and a whole host of projects that relate to gardening, alternate energy systems and recycling. I have spent the last 30 years of life working with computers and terrible toll they take on people, that the above is simply to keep my mind interested in a subject from an industry I look forward to leaving one day.
