doc: c++: promote api.token.raw
build: fix compatibility with old compilers
examples: reccalc: compile cleanly in C99
The Java enums are very different from the C model. As a consequence,
one cannot "build" an enum directly from an integer, we must retrieve
it. That's the purpose of the SymbolType.get class method.
* data/skeletons/java.m4 (b4_symbol_enum, b4_case_code_symbol)
(b4_declare_symbol_enum): New.
* data/skeletons/lalr1.java: Use SymbolType,
SymbolType.YYSYMBOL_YYEMPTY, etc.
* examples/java/calc/Calc.y, tests/local.at: Adjust.
This reverts commit ebab1ffca8.
This commit removed "useless" initializers, going from
/* YYPACT[STATE-NUM] -- Index in YYTABLE of the portion describing
STATE-NUM. */
private static final byte yypact_[] = yypact_init ();
private static final byte[] yypact_init ()
{
return new byte[]
{
25, -7, -8, 37, -8, 40, -8, 20, -8, 61,
-8, -8, 3, 9, 51, -8, -8, -2, -2, -2,
-2, -2, -2, -8, -8, -8, 1, 66, 66, 3,
3, 3
};
}
to
/* YYPACT[STATE-NUM] -- Index in YYTABLE of the portion describing
STATE-NUM. */
private static final byte[] yypact_ =
{
25, -7, -8, 37, -8, 40, -8, 20, -8, 61,
-8, -8, 3, 9, 51, -8, -8, -2, -2, -2,
-2, -2, -2, -8, -8, -8, 1, 66, 66, 3,

But it turns out that this was on purpose, to work around the 64KB
limitation in JVM methods. It was introduced on the 2008-11-10 by
Di-an Jan in 09ccae9b18: "Work around
Java's ``code too large'' problem for parser tables". See
https://lists.gnu.org/r/help-bison/2008-11/msg00004.html. A real
test, where we would hit the JVM limitation, would be nice.
To avoid further regressions, add comments.
The error format should be translated, but contrary to the case of
C/C++, we cannot just depend on macros to adapt on the
presence/absence of '_'. Let's consider that the message format is to
be translated iff there are some internationalized tokens.
* src/output.c (prepare_symbol_names): Define b4_has_translations.
* data/skeletons/java.m4 (b4_trans): New.
* data/skeletons/lalr1.java: Use it to emit translatable or not the
format string.
In Java there is no need for N_ and yytranslate_. So instead of
hard-coding the use of N_ in the table of the symbol names, rely on
b4_symbol_translate.
* src/output.c (prepare_symbol_names): Use b4_symbol_translate instead
of N_.
* data/skeletons/c.m4 (b4_symbol_translate): New.
* data/skeletons/lalr1.java (yysymbolName): New.
Use it.
* examples/java/calc/Calc.y: Use parse.error=detailed.
* tests/calc.at: Check parse.error=detailed.
There are many macros that are defined and used just
once (b4_public_if, b4_abstract_if, etc.). That's overkill. Rather,
let's define a macro to build the "public class YYParser" line.
It appears that the same syntax with "extends", "abstract", etc. is
implemented in the D parser, which looks very fishy...
* data/skeletons/d.m4, data/skeletons/java.m4 (b4_public_if)
(b4_abstract_if, b4_final_if, b4_strictfp_if): Replace with
(b4_parser_class_declaration): this.
* data/skeletons/lalr1.d, data/skeletons/lalr1.java: Adjust.
The previous name was historical and inconsistent.
* src/muscle-tab.c (define_directive): Use the proper value passing
syntax, based on the muscle kind.
(muscle_percent_variable_update): Use the right value passing syntax.
Migrate from parser_class_name to api.parser.class.
* data/skeletons: Migrate from parser_class_name to api.parser.class.
* doc/bison.texi (%define Summary): Document both parser_class_name
and api.parser.class.
Promote the latter over the former.
