any lr(1) wizards still there?

[Martin Grabmueller]

Hello list,

today I had a look at the old stuff in the guile-rgx-ctax module,
especially the lr(1)-parser generator contained in the lang
subdirectory.  At first it seemed easy to port it to Guile 1.5, but
then I found out that the source is from times when #f and '() was
both false.  In quite some places it was easy to fix, but in others...

Deep in the guts of the LR(1)-generator-phase there is a lot of code
which tries to take the CAR of #t, and I managed to localize where,
but when I tried to fix it, I felt the brain-slugs attacking and
decided to C-c k <RET>.

So the question is: Is there anybody around who eats sophisticated
optimized fancy generalized high-level Algorithms for breakfast, or
maybe even one of the original authors?

Thanks,
