c613a5e7dc Fix breakage introduced in rev.1.7. yystacksize and yysslim are global and
should be prefixed by YYPREFIX as well.

Only relevant if -p <yyprefix> is used. Used in cases where multiple parsers
are used in executable.

87be6e697a Fixed breakage of K&R support in rev.1.26. yyparse() was defined as
`int yyparse(;) ; { ... }' in K&R mode.  Getting rid of the second
unwanted semicolon in this made the ifdef tangle more tangled than
before.  Fixed a backwards comment in the tangle.

dd079f6ca5 Fixed breakage of K&R support in rev.1.8 of output.c: don't generate
#elif.  Cleaned up rev.1.8 a bit more: generate the #include of
<stdio.h> closer to the code that needs it.

484620e2e4 Make "YYPARSE_PARAM" and "YYPARSE_PARAM_TYPE" C++/ANSI-C clean. 1999-10-28 15:18:05 +00:00
David E. O'Brien
c3584b3b4e Allow a user specified parameter to 'yyparse()', in a manner similar to
that used by bison.  The names are consistent with the bison implementation
but this one also allows the type of the parameter to be specified.

For a desired prototype of:

	int yyparse __P((struct yyresult *));

and compile like this:

	yacc -dv grammar.y
	cc -c -DYYPARSE_PARAM_TYPE="struct yyresult *" \
	      -DYYPARSE_PARAM="parm" y.tab.c

and use like this:

	${
	#include "usrtypes.h"
	#include "usrproto.h"
	}$

	%token NUMBER

	%%

	goal : NUMBER
		{
		parm->value = yylval;
		} ;

If YYPARSE_PARAM_TYPE isn't specified then "void *" is the default type.
If YYPARSE_PARAM is not specified then the generated code behaves exactly
as traditional byacc.

892d5804bb Don't output rcsid into the output parser. It may have already been

it also fixes that fact that this file badly needed to be regenerated due

7c71e88713 Clean up the skeleton code a little. There was a #ifdef to avoid
stdlib.h unless on C++.  However, we already included it above, so there
was no point using the redundant declarations instead.

fae4b464e3 Use mkstemp rather than mktemp for yacc's temp files. This change was made
to OpenBSD a long time ago and to my tree shortly thereafter.  I think theo
made this change, or one similar to it, but I could be wrong.
