The current CVS Bison will generate dot files instead of VCG files. This
change was made some time ago (
http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00047.html), but
has not yet found it's way into a release version.

There is a TODO file in the Bison cvs distribution. You can look here:

Ofcourse, I understand what you meant here was to instrument the
*generated* parser with such tracing ability. Is that correct ?
I cannot edit my proposal now, so pls consider this as a part of it.

I'd think we need an m4 skeleton to output info into XML. Why do we
need a grammar for the report structure ?
thanks,

This is not about headers. It is a linker error. Be sure that you have
compiled the lexer generated by flex (lex.yy.c or whatever) and then link
the object file when you compile the parser. We can help you better if you
post your compile commands.

No, you dont need to use the C++ skeleton. Just put an extern "C"
declaration at the beggining of your parser file (.y file) e.g.,
extern "C"
{
int yyparse ( void );
int yylex ( void );
int yywrap ();
void yyerror ( char* );
}

Work expands to fil
sp[-2] etc.) otherwise it is best to insert a printf("..",
$1); inside the semantic action.

hi,
I am experimenting with various possibilities of helping people understand
Bison (and parsing in general) better. I have currently implemented a gdb
style
switch(yyn)
{
... /* your actions for each rule */
}
just comment out this switch statement and compile the C file. As far as I
know, there is no option to generate only the parser without actions.

hi,
Nope. I don't think so. The standard Bison distribution (1.2.8) is at:
http://ftp.gnu.org/pub/gnu/bison/bison-1.28.tar.gz
The files included in the above archive are the only files that will be
installed. I am not one of the maintainers of Bison but this my
understanding.

ot;. Dick Grune has
also written a parsing book free online; I think it is mentioned in
the comp.compilers FAQ.
Yes, that is tre . The LR parser is a PDA (an automaton that can
recognize a CFG). Do you mean I should mention that in my document?

The case statements execute the semantic actions in your grammar; so if you
can reduce the number of semantic actions, yyparse() function will be
smaller (there is one case for each rule that has an action associated with
it);

YYSTYPE is int -- otherwise use the appropriate field of the union.
and then you can use yylval to print the value in the error message...
(infact now it becomes the $x of the token in your grammar):
Hope this helps.

3. Comiple a.l --> lex.yy.c
$ flex a.l
4. Compile lex.yy.c -->lex.yy.o (compile only)
$ gcc -c lex.yy.c
5. Compile a.tab.c --> a.tab.o (Compile only)
$ gcc -c a.tab.c
6. Now link both into the final executable
$ gcc -o calc a.tab.o lex.yy.o
7. Execute calc program and enjoy your day
Sorry for a small digression, but are we moving toward implementing
probablistic CFGs in bison? or is my understanding very oblique..
thanks!

Sure. I will do that. When I was looking for documentation, I missed

Thanks for pointing out. Any tips/starting points for me in reading
bison code?
