+ tests: clean up push.at test group titles.
+ * tests/push.at: Remove "Push Parsing: " from test group titles
+ because these are already under the banner "Push Parsing Tests".
+
+2009-09-12 Alex Rozenman <rozenman@gmail.com>
+
+ Provide an additional sub-message for clarity.
+ Add "symbol not found in production" error message when
+ an "invalid reference" is detected in named references
+ resolution.
+ * src/scan-code.l: Update "invalid reference" case.
+ * tests/named-ref.at: Adjust test-cases.
+
+2009-09-10 Joel E. Denny <jdenny@clemson.edu>
+
+ Clean up yacc.c a little.
+ * data/yacc.c: Clean up M4 for readability, and make output
+ whitespace more consistent. For the main parse function
+ comment, instead of saying "yyparse or yypush_parse", say either
+ "yyparse" or "yypush_parse" depending on which it actually is.
+
+2009-09-10 Joel E. Denny <jdenny@clemson.edu>
+
+ Fix --enable-gcc-warnings.

+
+ lalr1.cc: syntax_error as exceptions.
+ It is common to use sort of factories in the user actions. These
+ factories may check some "syntactic" constraints that are not
+ enforced by the grammar itself. This is possible using YYERROR
+ within the action itself. Provide the user with a means to throw
+ a syntax_error exception.
+
+ * data/c++.m4 (b4_public_types_declare, b4_public_types_define):
+ Declare and define yy::parser::syntax_error.
+ * data/lalr1.cc: Include stdexcept.
+ (yy::parser::parse): Wrap the user action within a try/catch.
+ * data/glr.cc: Include stdexcept.
+
+2009-09-09 Akim Demaille <demaille@gostai.com>
+
+ lalr1.cc: add missing "inline".
+ * data/c++.m4 (b4_public_types_define): Add missing inline to
+ implementations provided in headers.

+ Changes some examples to demonstrate it.
+ (Calc++ Parser): Use %param.

+ Provide a means to factor lex-param and parse-param common
+ declarations.
+
+ * src/parse-gram.y (param_type): New.
+ Define a %printer for it.
+ (add_param): Use it.
+ (%parse-param, %lex-param): Merge into...

+ Adjust the grammar to use it.

+ Use it to support %parse-param, %lex-param and %param.
+
+2009-09-03 Joel E. Denny <jdenny@clemson.edu>
+
+ Use aver not assert.
+ * src/output.c: Don't include assert.h.
+ (output_skeleton): Use aver not assert.
+ * src/system.h (aver): In documentation of why, add links to
+ Paul Eggert's explanations in the mailing lists.
+
+2009-09-05 Alex Rozenman <rozenman@gmail.com>
+
+ Use "Unresolved reference" error message when no symbols were found
+ in a symbolic reference resolution. Remove .expr and -expr from
+ the shown reference when the reference is unresolved.
+ * src/scan-code.l: Change the error message, adjust location columns,
+ rename variable "exact_mode" to "explicit_bracketing".
+ * tests/named-ref.at: Adjust existing tests and add a new one.

+ src/parse-gram.y.

+
+2009-09-03 Joel E. Denny <jdenny@clemson.edu>
+
+ Don't suppress warnings about unused parse.error.
+ * data/bison.m4 (b4_error_verbose_flag): Don't examine value of
+ %define variable parse.error unless b4_error_verbose_flag is
+ actually expanded in a skeleton.
+
+2009-09-03 Akim Demaille <demaille@gostai.com>

+ * src/scan-code.h (code_props_rule_action_init): Rename
+ named_ref arg to name so it doesn't shadow named_ref type. This
+ makes it consistent with the function definition in scan-code.l
+ anyway.
+
+2009-08-28 Joel E. Denny <jdenny@clemson.edu>
+
+ %define: accept unquoted values.

+ Avoid compiler warning.
+

+
+ tests: use perl for printing special sequences to files.
+ And skip tests if perl is not available. This is better than
+ playing tricks with shell portability. Suggested by Akim
+ Demaille.
+ * tests/input.at (Bad character literals): Use it here for
+ omitting final newlines.
+ (Bad escapes in literals): Use it here for special characters.
+
+2009-08-26 Joel E. Denny <jdenny@clemson.edu>
+
+ tests: show a use of %define lr.default-reductions "consistent"
+ * tests/conflicts.at (%nonassoc and eof): Extend to test that it
+ prevents the omission of expected tokens for %error-verbose.
+
+2009-08-26 Akim Demaille <demaille@gostai.com>
+
+ tests: portability fix.
+ * tests/input.at (Bad escapes in literals): Don't expect "echo
+ '\0'" to output \ then 0.

Actually handle the yytable zero value correctly this time.
