* data/bison.m4 (b4_percent_define_flag_if): Correct comments on how
values are interpreted.
* doc/bison.texinfo (Decl Summary): Clean up and extend %define
documentation a little more.
* src/muscle_tab.c (MUSCLE_USER_NAME_CONVERT,
muscle_percent_define_insert, muscle_percent_code_grow): New
functions/macros.
* src/muscle_tab.h (muscle_percent_define_insert,
muscle_percent_code_grow): Prototype.
* src/parse-gram.y (prologue_declaration): Use
muscle_percent_define_insert and muscle_percent_code_grow when parsing
%define and %code directives.
Make it easy to share %define boolean variables between the front-end
and back-end. Though not used yet, this will be useful in the future.
* data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
Bison uses of names rather than just skeleton uses of names.
(b4_percent_define_get, b4_percent_define_ifdef): Rename
b4_percent_define_skeleton_variables(VARIABLE) to
b4_percent_define_bison_variables(VARIABLE).
(b4_percent_code_get, b4_percent_code_ifdef): Rename
b4_percent_code_skeleton_qualifiers(QUALIFIER) to
b4_percent_code_bison_qualifiers(QUALIFIER).
(b4_check_user_names_wrap): Update for renames.
* src/muscle_tab.c, src/muscle_tab.h (muscle_percent_define_flag_if,
muscle_percent_define_default): New functions mimicking
b4_percent_define_flag_if and b4_percent_define_default.
For %define variables, report locations for invalid values and
redefinitions.
* data/bison.m4 (b4_percent_define_flag_if): Read
b4_percent_define_loc(VARIABLE) to report the location of an invalid
value for VARIABLE.
(b4_percent_define_default): Save a special location in
b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
must later be reported as invalid.
* src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
functions.
(muscle_percent_define_insert): Record the location of VARIABLE in
muscle percent_define_loc(VARIABLE), and use it to report the previous
location for a redefinition.
(muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
(muscle_percent_define_default): Update like b4_percent_define_default.
(muscle_grow_user_name_list): Rename to...
(muscle_user_name_list_grow): ... this for consistency and use
muscle_location_grow.
* src/muscle_tab.h (muscle_location_grow): Prototype.
* tests/input.at (%define errors): Update expected output.
* tests/skeletons.at (%define boolean variables: invalid skeleton
defaults): New test case.
* 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 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.
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.
(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.
* tests/skeletons.at (installed skeleton file name): Rename to...
(installed skeleton file names): ... this.
Discussed starting at
<http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
* doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
(Bison Options): Document in --skeleton entry.
* src/output.c (output_skeleton): Use strncpy rather than strcpy since
full_skeleton can't necessarily hold all of pkgdatadir.
If the specified skeleton file name contains a `/', don't prepend
pkgdatadir.
* src/parse-gram.y (prologue_declaration): If the specified skeleton
file name contains a `/', prepend the grammar file directory.
* tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
* skeletons.at: New file.
(relative skeleton file names): New test case.
(installed skeleton file names): New test case.
* tests/testsuite.at: Include skeletons.at.
* bootstrap: Update copyright to 2007.
