-
- Implement @gettext<...@> directive to call gettext from skeletons. It
- can be used anywhere including inside arguments of directives of the
- form @foo(...@). Eventually, it should be possible to write an
- xgettext-like utility to extract @gettext<...@> text from skeletons.
- * data/bison.m4 (b4_check_user_names): Use @gettext<...@> when invoking
- b4_warn_at since b4_warn_at doesn't invoke gettext anymore.
- * data/glr.cc, data/lalr1.cc: Likewise but for b4_fatal and
- b4_complain reporting a push-parsing request or a missing %defines.
- * src/scan-skel.l (INITIAL): Recognize `@gettext<' to start...
- (SC_AT_GETTEXT_ARG): ... this new start condition where gettext is
- invoked.

+
+ Clean up.
+ * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
+ at_directive_argv arguments so these no longer have to be global
+ variables. Also, update the implementation for the following changes.
+ (fail_for_at_directive_too_many_args,
+ fail_for_at_directive_too_few_args): Add at_directive_name argument.
+ (at_directive_name): Remove as at_directive_argv[0] will be used for
+ this now.
+ (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
+ for the directive name.
+ (at_directive_argc, at_directive_argv): Make these local within
+ skel_lex instead of global.
+ (INITIAL): Update directive start action for above changes.
(SC_AT_DIRECTIVE_ARG): Rename to...
- (SC_AT_DIRECTIVE_ARGS): ... this, and recognize `@gettext<' to start
- SC_AT_GETTEXT_ARG.
- (at_directive_perform): Don't invoke gettext for @warn(...@),
- @warn_at(...@), etc. Instead, let the skeletons decide what should be
- passed to @gettext<...@>.
- * tests/skeletons.at (@gettext<...@>): New test case.
-
+ (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
+ (SC_AT_DIRECTIVE_SKIP_WS): Update.
+ (scan_skel): Move yylex_destroy to...
+ (skel_scanner_free): ... here.
* tests/skeletons.at (installed skeleton file name): Rename to...
(installed skeleton file names): ... this.
+2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * ChangeLog: For changes in doc/bison.texinfo, consistently reference
+ node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
+ Summary" not "Directives".
+ * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
+ %code entry in "Decl Summary" rather than the one in "Table of Symbols"
+ since the former is now the more complete one.
+ (Prologue Alternatives): Likewise and do the same for %defines.
+ (Table of Symbols): Add summary of %code, add summary of %define, and
+ move full %code documentation to...
+ (Decl Summary): ... here for consistency with other entries in these
+ sections.
+ Move %define entry in order to keep this list alphabetized.
+ Reword %define entry a little to put less emphasis on the skeleton
+ concept, which most users shouldn't have to think about.
+
+2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ Adjust to recent gnulib changes.
+ * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
+ Add string.h, string_.h, unistd_.h, wchar_.h.
+ * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
+ * src/system.h: Don't include <stpcpy.h>; this is now done by
+ <string.h>.
+
+2007-01-23 Paolo Bonzini <bonzini@gnu.org>
+
+ Simplify implementation of unqualified %code, implement macros for
+ uniform treatment of boolean %define flags. Document %define.
+ * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
+ b4_percent_code_ifdef): New.
+ (b4_percent_code_get): Map unqualified %code to b4_percent_code().
+ * data/c++.m4: Define default value for global_tokens_and_yystype.
+ * data/glr.cc: Likewise.
+ * data/location.cc: Use b4_percent_define_flag_if.
+
+ * doc/bison.texinfo (Decl Summary): Document %define.
+
+ * src/parse-gram.y (Unqualified %code): Change muscle name to
+ b4_percent_code().
+ (content.opt): Default to empty.
+

in the yychar entry.
In the yychar entry, remove mention of the local yychar case (pure
parser) since this is irrelevant information when writing semantic

isn't when semantic actions are deferred.
