Note that api.tokens.prefix has not been released, yet.
* NEWS, data/bison.m4, doc/bison.texi, tests/c++.at,
* tests/calc.at, tests/java.at, tests/local.at: Do it.
* src/muscle-tab.c (muscle_percent_variable_update): Ensure
backward compatibility.
* tests/c++.at (Exception safety): Don't use swap here, it
is useless.
Cover more test cases: yyerror, YYERROR, YYABORT, and
error recovery.
(Object): Instead of just keeping a counter of instances, keep
a list of them.
* tests/c++.at (Exception safety): Let the parser support the --debug
option.
On 'p', throw an exception from the %printer.
* data/lalr1.cc (yyparse): Do not display the values we discard, as it
uses %printer, which might have thrown the exception.
* data/lalr1.cc: Check size > 1, rather than size != 1, when cleaning
the stack, as at the beginning, size is 0.
* tests/c++.at (Exception safety): Check exception safety in
%initial-action.

* tests/c++.at (AT_CHECK_VARIANTS): here.
* src/symtab.h (symbol_list): Represent semantic types as structure
'semantic_type'.
* src/symlist.c (symbol_list_type_new): Allocate this structure.
(symbol_list_code_props_set): Set this semantic type's status to used if it
was not declared.
* src/symtab.c (semantic_types_sorted): New.
(semantic_type_new): Set the new semantic type's location appropriately.
(symbol_check_defined): If a symbol has a type, then set this type's status
to "declared".
(semantic_type_check_defined, semantic_type_check_defined_processor): Same
as symbol_check_defined and symbol_check_defined_processor, but for semantic
types.
(symbol_check_defined): Check semantic types usefulness.
* src/symtab.h (semantic_type): New fields 'location' and 'status'.
* src/symtab.h, src/symtab.c (semantic_type_new)
(semantic_type_from_uniqstr, semantic_type_get): Accept a location as a
supplementary argument.
* tests/input.at (Unassociated types used for printer of destructor): New.
* tests/c++.at (AT_CHECK_VARIANTS): Fix an error caught by this commit.
* tests/c++.at (Syntax error as exception): Avoid spurious failure
at least when compiling with g++-4.7.x due to lack of declaration
of getenv. Include <stdlib.h>.
* data/lalr1.cc (parse): Catch syntax_error around yylex and
forward them to errlab1.
* tests/c++.at (Syntax error as exception): Check support for
syntax exceptions raised by the scanner.
* NEWS, doc/bison.texinfo: Document it.
This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
Currently, there is no check that %printer ... <foo> (nor
%destructor) is about an existing <foo> type. This C++ test had
it wrong (<::std::string> vs. <std::string>).
* tests/c++.at (AT_CHECK_VARIANTS): In list.yy, redefine the
pretty-printing of lists into something better for parser traces.
Update the expected output.
Fix correspondance between %type/%token and %printer.
* data/lalr1.cc (yyreduce): Compute the resulting state before
running the user action so that yylhs is a valid symbol.
(yyerrorlab): Since yylhs is complete (it knows its type), we can
simply call yy_destroy_ to destroy $$ on YYERROR invocations.
* tests/c++.at (AT_CHECK_VARIANTS): Test YYERROR with variants.
Discussed in
http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00033.html
* data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
New.
(b4_percent_define_use): New.
Use it where applicable.
* data/c++.m4: Replace uses of the variable "namespace" by
"api.namespace".
Default the latter to the former.
* doc/bison.texinfo (Decl Summary): Document "namespace" as
obsolete.
Document api.namespace.
Use @samp to document %define uses, keep @code for identifiers.
* NEWS: Likewise.
* tests/c++.at, tests/input.at: Test api.namespace instead of
namespace. (The tests passed with namespace.)
* src/getargs.c (command_line_location): Set parameters to void.
* src/output.c (symbol_type_name_cmp): Make static.
(symbols_by_type_name): Set parameters to void.
(symbol_definitions_output): Remove unused parameter. Rename as...
(prepare_symbol_definitions): this.
(muscles_output): Move symbol_definitions_output to...
(output): here as prepare_symbol_definitions.
* tests/c++.at (AT_CHECK_VARIANTS): Remove unused parameters of main.
(AT_CHECK_NAMESPACE): Make unused parameter lloc unnamed.
There are two issues to handle: first scanning nested angle bracket pairs
to support types such as std::pair< std::string, std::list<std::string> > >.
Another issue is to address idiosyncracies of C++: do not glue two closing
angle brackets together (otherwise it's operator>>), and avoid sticking
blindly a TYPE to the opening <, as it can result in '<:' which is a
digraph for '['.
* src/scan-gram.l (brace_level): Rename as...
(nesting): this.
(SC_TAG): New.
Implement support for complex tags.
(tag): Accept \n, but not <.
* data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
(b4_symbol_variant): Leave space around types as parameters.
* examples/variant.yy: Use nested template types and leading ::.
* src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
Rename as...
(TAG, TAG_ANY, TAG_NONE, tag.opt): these.
* tests/c++.at: Test parametric types.
This is not sufficient, but we test at least that the make_SYMBOL
interface is not affected by token.prefix. A more general test
will be implemented when the support of token.prefix is generalized
to more skeletons.
* tests/c++.at: One more variant test, using token.prefix.
* data/lalr1.cc (_b4_args, b4_args): New.
Adjust all uses of locations to make them optional.
* tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
(AT_CHECK_NAMESPACE): Check the use of locations.
* tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
without locations with lalr1.cc.
Test these cases.
* tests/output.at: Check lalr1.cc with and without location
support.
* tests/regression.at (_AT_DATA_EXPECT2_Y, _AT_DATA_DANCER_Y):
Don't use locations.
This improves the "list" bench by 2%.
* data/lalr1.cc (variant::build): Add an overloaded version with
an argument.
* tests/c++.at (AT_CHECK_VARIANT): Check it.
