+
+ * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
+ instead of muscle_insert for %define values so that M4-special
+ characters are replaced with digraphs.
+ * tests/input.at (%define errors): Extend to check weird values.

+
+ Instead of having skeletons declare all valid %define variables and
+ %code qualifiers, provide macros that retrieve the associated values
+ and build these lists automatically. Thus Bison will now warn when a
+ variable or qualifier is not used by the skeleton in the current
+ invocation regardless of whether it might sometimes be used by that
+ skeleton in other invocations. Also, move all %define value macros to
+ the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
+ form, which is replaced by %code.
+ * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
+ (b4_check_user_names): ... this, and change the series of valid name
+ arguments to a single list argument for names used in the skeleton
+ similar to the existing list argument for names used in the grammar.
+ Warn instead of complaining.
+ (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
+ values and %code code, to format %code code properly, and to build
+ lists of all %define variables and %code qualifiers used in the
+ skeleton: b4_skeleton_percent_define_variables and
+ b4_skeleton_percent_code_qualifiers.
+ (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
+ Remove, and...
+ (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
+ the skeleton names lists can finish building first. In place of
+ b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
+ expect the lists b4_user_percent_define_variables and
+ b4_user_percent_code_qualifiers.
+ * data/c++.m4: Where setting default values for b4_parser_class_name,
+ b4_location_type, b4_filename_type, b4_namespace, and
+ b4_define_location_comparison, update their names to the
+ b4_percent_define_ namespace.
+ * data/glr.c: Don't use b4_check_percent_define_variables and
+ b4_check_percent_code_qualifiers. Use b4_get_percent_code.
+ * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
+ (b4_parser_class_name, b4_namespace): Define these using
+ b4_get_percent_define for parser_class_name and namespace. Normally
+ this would be a bad idea since there might be cases when the variables
+ aren't used, but these variables are too pervasive in these skeletons
+ for that to be a problem.
+ * data/location.cc: Use b4_get_percent_define.
+ * data/push.c: Don't use b4_check_percent_define_variables and
+ b4_check_percent_code_qualifiers. Use b4_get_percent_code.
+ * data/yacc.c: Likewise, and don't call m4_exit in
+ b4_use_push_for_pull_if or m4_wrap code will never execute.
+ * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
+ Rename to...
+ (muscle_grow_user_name_list): ... this for consistency with the
+ terminology used in bison.m4.
+ * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
+ %define variable names, and rename muscle used_percent_define_variables
+ to user_percent_define_variables.
+ (grammar_declaration): Rename muscle used_percent_code_qualifiers to
+ user_percent_code_qualifiers.
+ (content): Remove.
+ (content.opt): Replace content RHS with STRING RHS so %define "NAME"
+ {CODE} form is no longer accepted.
+ * tests/input.at (Reject bad %code qualifiers): Rename to...
+ (Reject unused %code qualifiers): ... this, and update test output.
+ (%define error): Update test output.
