* doc/bison.texi (%define Summary): Use @deffn instead of @table, it
spares a lot of width, especially in PDF, and looks nicer in the other
formats too.
It is also more consistent with the rest of the document.
This is consistent with the other %define variable names.
* data/java.m4: Use api.value.type instead of stype.
* doc/bison.texi, NEWS: Document that change.
* src/muscle-tab.c (muscle_percent_variable_update): Provide backward
compatibility.
* tests/java.at: Adjust.
So far we were issuing two lines for each syncline change:
/* Line 356 of yacc.c */
#line 1 "src/parse-gram.y"
This is a lot of clutter, especially when reading diffs, as these
lines change often. Fuse them into a single, shorter, line:
#line 1 "src/parse-gram.y" /* yacc.c:356 */
* data/bison.m4 (b4_syncline): Issue a single line.
Comment improvements.
(b4_sync_start, b4_sync_end): Issue a shorter comment.
* data/c++.m4 (b4_semantic_type_declare): b4_user_code must be
on its own line as it might start with a "#line" directive.
* src/gram.c (print_lhs): Use %*s to indent.
* src/print_graph.c (print_lhs): Use obstack_printf.
Became simple enough to be inlined in...
(print_core): here.
Use a "rule*" instead of an index in "rules[]".
* src/location.c (location_caret): finish the line with one whether or not it
is present in input. Rewrite code without getline.
(cleanup_caret): Reset the caret_info global.
* bootstrap.conf: No longer require getline.
Unput was no longer used since a POSIX-compatiblity issue with Flex 2.5.31,
which has been adressed in newer versions of Flex. See this discussion:
<http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00029.html>
This partially reverts commit aa4180418f.
* src/scan-gram.l (unexpected_end): Here.
* tests/input.at: Adjust for new order of error reports.
The commit 38de4e570f underquoted the
content of the comments, which resulted in losing square brackets in
the comments. Besides, some other invocations were underquoting the
effective arguments.
* data/c.m4 (b4_comment_): Properly quote the comment.
(b4_comment_, b4_comment): Move to...
* data/c-like.m4: here, so that...
* data/java.m4: can use it instead of its own copy.
* data/bison.m4 (b4_integral_parser_tables_map): Fix some comments.
* data/lalr1.cc, data/lalr1.java, data/yacc.c: Comment fixes.
* data/lalr1.cc: Reorder a bit to factor some CPP directives.
* src/tables.c (save_column, pack_vector): Reduce the scope to
emphasize the structure of the code.
Rename the returned value "res" to make understanding easier.
The YYLEX existed only to support YYLEX_PARAM, which is now removed.
This macro was a nuisance, since incorrect yylex calls where pointed
the macro _use_, instead of its definition.
* data/c.m4 (b4_lex_formals, b4_lex): New.
* data/glr.c, data/yacc.c: Use it.
* data/lalr1.cc (b4_lex): New.
Use it.
squash! skeletons: no longer call yylex via a CPP macro
* data/c.m4 (b4_token_enum): Improve comments.
(b4_value_type_define, b4_location_type_define): New, extracted
from...
(b4_declare_yylstype): here.
Separate the typedefs from the union/struct definitions.
* tests/input.at: Rename some AT_SETUP to avoid that
AT_SETUP_STRIP thinks they contain %define directives.
("%define" backward compatibility): Merge tests together
to speed up the test suite, and to make maintenance easier
(multiple AT_CHECK means multiple runs of the test suite to
be sure to have updated all the error messages).
Check the "%define variant" is properly obsoleted.
* src/muscle-tab.c (define_directive): Be robust to "assignment"
containing '='.
(muscle_percent_variable_update): Upgrade "variant" to "api.value.type".
Support such upgrade patterns.
Adjust callers.
* data/bison.m4: Use api.value.type for variants.
* tests/c++.at: Adjust tests.
Instead of
warning: deprecated %define variable name: 'namespace', use 'api.namespace' [-Wdeprecated]
display (in -fno-caret mode):
warning: deprecated directive: '%define namespace foo', use '%define api.namespace foo' [-Wdeprecated]
and (in -fcaret mode):
warning: deprecated directive, use '%define api.namespace toto' [-Wdeprecated]
%define namespace toto
^^^^^^^^^
This is in preparation of cases where not only the variable is
renamed, but the values are too:
warning: deprecated directive: '%define variant', use '%define api.value.type variant' [-Wdeprecated]
* src/muscle-tab.c (define_directive): New.
(muscle_percent_variable_update): Take the value as argument, and use it
in the diagnostics.
Loop with a pointer instead of an index.
* tests/input.at (%define backward compatibility): Adjust.
Improve the output by ensuring a well defined order for type switches.
* src/uniqstr.h: Style changes for macro arguments.
(UNIQSTR_CMP): Replace by...
(uniqstr_cmp): this.
* src/uniqstr.c (uniqstr_cmp): New.
Produce well defined results.
* src/output.c: Use it.
* tests/local.at (AT_SETUP_STRIP): New.
(AT_SETUP): Use it to shorten the test titles: remove %defines, %language
and %skeleton whose arguments suffice.
* tests/synclines.at: Use more precise AT_SETUP.
This is mostly used for the license header, the synclines, and the
generated tables:
- /* STOS_[STATE-NUM] -- The (internal number of the) accessing
- symbol of state STATE-NUM. */
+ // STOS_[STATE-NUM] -- The (internal number of the) accessing
+ // symbol of state STATE-NUM.
static const unsigned char yystos_[];
* data/c.m4: Comment changes.
(b4_comment_): Expand the text argument.
Before this change, we were actually formatting M4 code as a
C comment, and then expand it.
(b4_comment): Fix the closing of comments: there is no reason to
add the (line) prefix before the closing "*/".
* data/c++.m4 (b4_comment): New.
The "variant" structure provides a means to store, in a typeless way,
C++ objects. Manipulating it without provide the type of the stored
content is doomed to failure. So provide a means to copy in a type
safe way, and prohibit typeless assignments.
* data/c++.m4 (symbol_type::move): New.
* data/lalr1.cc: Use it.
* data/variant.hh (b4_variant_define): Provide variant::copy.
Let variant::operator= abort.
We cannot undefine it, yet, as it is still uses by the implicit
assigment in symbols, which must also be disabled.
