+
+ More cleanup.
+ * src/reader.c (current_rule): Declare it static since it's no longer
+ used outside this file.
+ (grammar_current_rule_action_append): Remove redundant arguments from
+ translate_rule_action invocation.
+ * src/reader.h (current_rule): Remove this unused extern.
+ * src/scan-code.h (translate_rule_action): Remove redundant arguments.
+ * src/scan-code.l (translate_rule_action): Likewise.
+

+
+ Clean up yesterday's patch.
+ * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
+ to...
+ * src/reader.c (grammar_current_rule_action_append): ... here for
+ consistency with grammar_current_rule_symbol_append.
+ * tests/regression.at (Braced code in declaration in rules section):
+ Make yyerror and yylex static as usual.
+
+2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix bug that mistakes braced code in a declaration in the rules section
+ to be a rule action. Mentioned at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
+ * src/scan-gram.l: Move midrule action detection from the start of the
+ scanning of any braced code to...
+ * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
+ action. For readability, use $2 and @2 rather than the equivalent
+ global variables.
+ * tests/regression.at (Braced code in declaration in rules section):
+ New test to catch the error fixed by the above patch.
+
+ Work on code readability some.
+ * src/scan-code.l (current_rule): Get rid of this misleading and
+ redundant declaration: it's actually extern'ed in reader.h.
+ (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
+ translate_action): Add a rule argument and use it instead of the global
+ current_rule.
+ (translate_rule_action): This already receives current_rule through an
+ argument, so pass it on to translate_action instead of assigning
+ current_rule to current_rule.
+ (translate_symbol_action, translate_code): Pass rule = NULL to
+ translate_action.

+
+ Rename %before-definitions to %start-header and %after-definitions to
+ %end-header. Don't use these declarations to separate pre-prologue
+ blocks from post-prologue blocks. Add new order-independent
+ declarations %before-header and %after-header as alternatives to the
+ traditional Yacc pre-prologue and post-prologue blocks. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
+ * NEWS (2.3+): Update for these changes.
+ * data/glr.c (b4_before_definitions): Update to...
+ (b4_start_header): ... this.
+ (b4_after_definitions): Update to...
+ (b4_end_header): ... this.
+ * data/glr.cc: Likewise.
+ * data/lalr1.cc: Likewise.
+ * data/yacc.c: Likewise.
+ * doc/bison.texinfo (The prologue): Update names, and replace remaining
+ prologue blocks with %*-header declarations.
+ (Calc++ Parser): Likewise.
+ (Bison Declaration Summary): Update names.
+ (Bison Symbols): Update description.
+ * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
+ (PERCENT_END_HEADER): ... this.
+ (PERCENT_BEFORE_DEFINITIONS): Update to...
+ (PERCENT_START_HEADER): ... this.
+ (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
+ (declaration): Update token names and m4 macro names.
+ When parsing %end-header and %start-header, invoke translate_code
+ before muscle_code_grow, and no longer set global booleans to remember
+ whether these declarations have been seen.
+ Parse new %after-header and %before-header.
+ * src/reader.c (before_definitions, after_definitions): Remove.
+ (prologue_augment): Accept a new bool argument to specify whether to
+ augment the pre-prologue or post-prologue.
+ * src/reader.h (before_definitions, after_definitions): Remove these
+ extern's.
+ (prologue_augment): Add new bool argument.
+ * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
+ (PERCENT_END_HEADER): ... this.
+ (PERCENT_BEFORE_DEFINITIONS): Update to...
+ (PERCENT_START_HEADER): ... this.
+ (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
+ * tests/actions.at (Printers and Destructors): Update names.
