Likewise for me. I took it as a grad course when I was an undergrad
at te University of Michigan. I enjoyed the programming but the
theory didn't seem to map to it, at least the way that prof taught it.
End result, "hated it"...
I took another compiler course during my Master's work at Johns
Hopkins. The only reason I took it was because a prof who had taught
two other classes (C++ and OOA&D) was teaching it and I really liked
his teaching method. He let us do the project with whatever tools we
wanted and I discovered PCCTS (1.10 at the time). The way he taught
it, the theory made sense and was interesting. It wasnt't just "the
mathematical definition of a context-free grammar is..." (which is the
way the Michigan guy taught it, yawn.) Sure, we went over that, but
instead of having the tests be regurgitations of definitions, it was
primarily applications of algorithms and writing grammars/REs. I
ended up really liking the stuff!

I work for Frank DeRemer (father of LALR) and with Tom ("Very Fast
LALR Parsers") Pennello at MetaWare. Great guys, and it's fun to
argue LL vs. LALR with them... not that I'll change their minds,

BINGO! The biggest problem with schools is that the only time parsing
concepts come up are in courses with scary names and reputations like
"Compiler Construction" and "Parsing Theory" (you know how everyone
jumps at the chance to take a course with "theory" in its title.
These are really useful methods and tools that most programmer don't
know exist. I've used yacc (yuck) and PCCTS (smile) for several non
compiler projects. Someday I'll write a book on "Parsers ain't just
Finally, I've got a twisted mind, and you need that to enjoy this
