12/20   Has anyone used the parser generator JavaCC?  Is it just me, or is
        it completely awful?
        \_ what do you need it for? If you need to use the visitor and
           traverse the syntax tree, I recommend JTB, available here
           http://compilers.cs.ucla.edu/jtb  It is built on top of
           javacc and generates visitors that you can extend functionalities

5/21    I was not a CS major and never took the compiler class.  What is
        a good book to help me write a compiler?  And what about interpreter?
        Do they basically involve the same issues except code generation and
        optimization?
        \_ Use the book by Robert Mak, called "Writing Interpreters and
           Compilers in C++." It's a practical, hands-on "lab" type book which

5/12    Are there any emacs modes for .l files (lex) and .y files (yacc)?  I'm
        running emacs20.  Thanks.
        \_ just use c-mode or c++-mode.

5/6     I've been out of school for too long.  If I want to write a simple
        compiler, what tools do I need besides yacc and what do they do?
        Thanks a bunch!
        \_ well there's also lex (flex) for the lexical analyzer (tokenizing).
        \_ java or c? if c, lex/flex=good tokenizer. yacc/bison are great
           for grammar. both are LALR so they're pretty powerful.

6/25    When yacc man page refers to "LR(1) parser", is LR(1) a reference to
        some other man page or does LR(1) have some other special meaning?
                -clueless
        \_ some other special meaning, LR(1) is a style of parse tree
           generation that has certain limitatations.  Sort of like how
           reg exps can't search for all the things you want to search for

7/16    Dear motd, is it true that the gnu implementation of C++ lacks
        <sstream>?  What gives?

           \_ what should we care about, java? eiffel? mh?

12/14   I totally don't see any relevance in teaching Lambda calculus in an

8/13    Is there such a thing as an algorithm that can output another

        \_ Yes. Not as glamorous as it sounds; see also: genetic algorithms,
           Remez algorithms, data-directed programming
        \_ bison, yacc, (f)lex, and many many more. not self tuning though.

1/18    Wanted 2 programmers to help develop web based apps:  Between the
        two, will need PERL, CGI, SQL, Yacc(or Bison), Javascript, HTML.
        Full time or Part time (20 hours minimum).  At least two weeks(tm)
        with possibilities of more if appropriate.  Work on-site (downTown

7/11    Since bison/yacc/(f)lex all act like state machines is there any way
        to implement a program with multiple context parsers (eg. a
        multithreaded network deamon that needs to parse an input)?
        \_ This problem is even worse in OpenGL that employ specialized
           rendering hardware since the GL libraries act on the state of
           the video card.  In other words, there's only one rendering
