*** K&C parsers
Support for generating parsers in K&R C will be removed. Parsers
- generated for C supprt ISO C90, and are tested with ISO C99 and ISO C11
+ generated for C support ISO C90, and are tested with ISO C99 and ISO C11
compilers.
*** Features deprecated since Bison 1.875
*** Guards (yacc.c, glr.c, glr.cc)
The generated headers are now guarded, as is already the case for C++
- parsers (lalr1.cc). For intance, with --defines=foo.h:
+ parsers (lalr1.cc). For instance, with --defines=foo.h:
#ifndef YY_FOO_H
# define YY_FOO_H
For the same reasons, the undocumented and unused macro YYLSP_NEEDED is no
longer defined.
+** New %define variable: api.prefix
+
+ Now that the generated headers are more complete and properly protected
+ against multiple inclusions, constant names, such as YYSTYPE are a
+ problem. While yyparse and others are properly renamed by %name-prefix,
+ YYSTYPE, YYDEBUG and others have never been affected by it. Because it
+ would introduce backward compatibility issues in projects not expecting
+ YYSTYPE to be renamed, instead of changing the behavior of %name-prefix,
+ it is deprecated in favor of a new %define variable: api.prefix.
+
+ The following examples compares both:
+
+ %name-prefix "bar_" | %define api.prefix "bar_"
+ %token <ival> FOO %token <ival> FOO
+ %union { int ival; } %union { int ival; }
+ %% %%

+ - this context is not passed to ancillary functions such as yyerror,

@section Multiple Parsers in the Same Program
Most programs that use Bison parse only one language and therefore contain
-only one Bison parser. But what if you want to parse more than one
-language with the same program? Then you need to avoid a name conflict
-between different definitions of @code{yyparse}, @code{yylval}, and so on.
-
-The easy way to do this is to use the option @samp{-p @var{prefix}}
-(@pxref{Invocation, ,Invoking Bison}). This renames the interface
-functions and variables of the Bison parser to start with @var{prefix}
-instead of @samp{yy}. You can use this to give each parser distinct
-names that do not conflict.
-
-The precise list of symbols renamed is @code{yyparse}, @code{yylex},
-@code{yyerror}, @code{yynerrs}, @code{yylval}, @code{yylloc},
-@code{yychar} and @code{yydebug}. If you use a push parser,
-@code{yypush_parse}, @code{yypull_parse}, @code{yypstate},
-@code{yypstate_new} and @code{yypstate_delete} will also be renamed.
-For example, if you use @samp{-p c}, the names become @code{cparse},
-@code{clex}, and so on.
+only one Bison parser. But what if you want to parse more than one language
+with the same program? Then you need to avoid name conflicts between
+different definitions of functions and variables such as @code{yyparse},
+@code{yylval}. To use different parsers from the same compilation unit, you
+also need to avoid conflicts on types and macros (e.g., @code{YYSTYPE})
+exported in the generated header.
+
+The easy way to do this is to define the @code{%define} variable
+@code{api.prefix} (possibly using the option
+@samp{-Dapi.prefix=@var{prefix}}, see @ref{Invocation, ,Invoking Bison}).
+This renames the interface functions and variables of the Bison parser to
+start with @var{prefix} instead of @samp{yy}, and all the macros to start by
+@var{PREFIX} (i.e., @var{prefix} upper cased) instead of @samp{YY}. You can
+use this to give each parser distinct names that do not conflict.
+
+The renamed symbols include @code{yyparse}, @code{yylex}, @code{yyerror},
+@code{yynerrs}, @code{yylval}, @code{yylloc}, @code{yychar} and
+@code{yydebug}. If you use a push parser, @code{yypush_parse},
+@code{yypull_parse}, @code{yypstate}, @code{yypstate_new} and
+@code{yypstate_delete} will also be renamed. The renamed macros include
+@code{YYSTYPE}, @code{YYSTYPE_IS_TRIVIAL}, @code{YYSTYPE_IS_DECLARED},
+@code{YYLTYPE}, @code{YYLTYPE_IS_TRIVIAL}, and @code{YYLTYPE_IS_DECLARED}.
+
+For example, if you use @samp{%define api.prefix c}, the names become
+@code{cparse}, @code{clex}, @dots{}, @code{CSTYPE}, @code{CLTYPE}, and so
+on.
+
+The @code{%define} variable @code{api.prefix} works in two different ways.
+In the implementation file, it works by adding macro definitions to the
+beginning of the parser implementation file, defining @code{yyparse} as
+@code{@var{prefix}parse}, and so on:
+
+@example
+#define YYSTYPE CTYPE
+#define yyparse cparse
+#define yylval clval
+...
+YYSTYPE yylval;
+int yyparse (void);
+@end example
+
+This effectively substitutes one name for the other in the entire parser
+implementation file, thus the ``original'' names (@code{yylex},
+@code{YYSTYPE}, @dots{}) are also usable in the parser implementation file.
+
+However, in the parser header file, the symbols are defined renamed, for
+instance:
-@strong{All the other variables and macros associated with Bison are not
-renamed.} These others are not global; there is no conflict if the same
-name is used in different parsers. For example, @code{YYSTYPE} is not
-renamed, but defining this in different ways in different parsers causes
-no trouble (@pxref{Value Type, ,Data Types of Semantic Values}).
+@example
+extern CSTYPE clval;
+int cparse (void);
+@end example
-The @samp{-p} option works by adding macro definitions to the
-beginning of the parser implementation file, defining @code{yyparse}
-as @code{@var{prefix}parse}, and so on. This effectively substitutes
-one name for the other in the entire parser implementation file.
+Previously, a similar feature was provided by the obsoleted directive
+@code{%name-prefix} (@pxref{Table of Symbols, ,Bison Symbols}) and option
+@code{--name-prefix} (@pxref{Bison Options}).

+
+Rename the external symbols (variables and functions) used in the parser so
+that they start with @var{prefix} instead of @samp{yy}. Contrary to
+@code{api.prefix}, do no rename types and macros.
+
+The precise list of symbols renamed in C parsers is @code{yyparse},
