* tests/local.at (AT_LEX_FORMALS, AT_LEX_ARGS, AT_LEX_PRE_FORMALS)
(AT_LEX_PRE_ARGS): Rename as...
(AT_YYLEX_FORMALS, AT_YYLEX_ARGS, AT_YYLEX_PRE_FORMALS)
(AT_YYLEX_PRE_ARGS): these, for consistency.
(AT_API_PREFIX): Take %name-prefix into account.
(AT_YYLEX_PROTOTYPE): New.
Use it.
* tests/actions.at, tests/calc.at, tests/cxx-type.at: Adjust to
use them.
* tests/local.at (AT_YYERROR_PROTOTYPE): New.
Use it.
* tests/cxx-type.at: Extensive revamp to use a more traditional
quotation scheme, and to use the generic yyerror implementation.
Prefer Autotest macros to CPP macros.
* tests/java.at: .
* tests/local.at (AT_YYERROR_DECLARE_EXTERN, AT_YYERROR_DECLARE)
(AT_YYERROR_DEFINE): Handle locations for C and C++.
* tests/calc.at: Use it for C++ (as C has extra arguments which
are not yet handled by AT_BISON_OPTION_PUSHDEFS).
* tests/actions.at: Adjust.
* tests/local.at (AT_LANG): Use c++ instead of cxx for C++.
Adjust dependencies.
(AT_YYERROR_DECLARE_EXTERN, AT_YYERROR_DECLARE): Issue nothing
for C++/Java.
(AT_YYERROR_DEFINE): Use m4_case.
(AT_JAVA_COMPILE): Use AT_SKIP_IF.
There is one difference: now, even without --defines, we generate
extern declarations for these variables. The factoring is worth it.
* data/c.m4 (b4_declare_yylstype): Declare them.
* data/glr.c, data/yacc.c: Adjust.
In order to improve the testing of %defines, which exports the
interface of the generated parser, change the calc.at tests so that
when %defines is passed, main will be in another compilation unit. It
loads the generated header.
* tests/calc.at (AT_CALC_MAIN): New.
Includes the definition of the global variables.
Therefore, now declare them from the %requires section of the parser.
Adjust to yydebug and yyparse being renamed by %name-prefix.
* data/c.m4 (b4_declare_yydebug): New.
* data/glr.c, data/yacc.c (b4_shared_declarations): Use it.
Remove the corresponding code from the parser body.
* NEWS: Doc this.
yacc.c used to include two almost identical sections: one for the *.h
file, and another for the *.c file. The main difference is that in
the *.c file we used the yy* names (as %name-prefix is handled by
"#define yy* <prefix>*" before), while the *.hh used <prefix>* names.
Keep only the later. If this is troublesome, b4_shared_declarations
can easily take the desired prefix as argument.
* data/yacc.c (b4_shared_declarations): New.
Use it to factor duplicated declarations.
yacc.c and glr.c share common declarations. Their YYLTYPE are exactly
equal, and their YYSTYPE are sufficiently alike to be fused (its
declaration was protected by YYSTYPE_IS_DECLARED in yacc.c, but not in
glr.c). Besides, yacc.c duplicated the definitions of YYLTYPE and
YYSTYPE (*.h/*.c).
* data/c.m4 (b4_declare_yylstype): New.
* data/yacc.c, data/glr.c: Use it.
Using http://github.com/lyda/misspell-check, massage its
output into sed commands to perform the suggested changes.
Initially, I filtered out the THRU->Through changes, because
that failed to retain capitalization in the grammar token.
Instead, do this manually, beforehand:
sed -i s/THRU/THROUGH/ tests/existing.at
git ls-files|misspellings -f -|perl -nl \
-e '/^(.*?)\[(\d+)\]: (\w+) -> "(.*?)"$/ or next;' \
-e '($file,$n,$l,$r)=($1,$2,$3,$4); $q="'\''"; $r=~s/$q/$q\\$q$q/g;'\
-e 'print "sed -i $q${n}s!$l!$r!$q $file"'|bash
Some versions of Flex, possibly modified by the distribution package
maintainers, have incompatible signatures. Since newer versions of
Flex prototype their functions, avoid the conflicts in that case.
Reported by Stefano Lattarini.
<http://lists.gnu.org/archive/html/bug-bison/2012-05/msg00012.html>.
* src/flex-scanner.h (FLEX_VERSION_GT): New.
Use it to issue prototypes for flex-generated functions only for
versions up to 2.5.31, in accordance with the comment.
See commit dc9701e848.
Use it to define yylex_destroy when needed.
