Denny + + Fix bug that mistakes braced code in a declaration in the rules section + to be a rule action. Mentioned at + . + * 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. + +2006-06-23 Joel E. Denny + + 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 + . + * 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. + 2006-06-22 Joel E.
