+
+ Some M4 cleanup in the testsuite.
+ Suggested by Eric Blake at
+ <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
+ * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
+ complicate the code by distinguishing between a missing value
+ and an empty string value for an optional argument. This fix is
+ allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
+ * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
+ (AT_TEST_TABLES_AND_PARSE): ... this now that the special
+ arguments are not needed because of the following changes.
+ Fix stale comments.
+ Bison developers should use GNU M4 and should not use
+ POSIXLY_CORRECT when building the test suite, so do not
+ complicate the code by avoiding $10 and above.
+ Do not quote an empty string value for an optional argument, and
+ do not distinguish between a missing value and an empty string
+ value.

+
+ Revert unnecessary column realignment in --help output.

+ * src/getargs.c (usage): Here.
+
+2009-07-04 Alex Rozenman <rozenman@gmail.com>
+
+ Alphabetical order in src/local.mk.
+ * src/local.mk: Adjust.
+
+2009-07-04 Alex Rozenman <rozenman@gmail.com>
+
+ Style changes and factoring.
+ * src/named-ref.h: Add comments.
+ * src/parse-gram.y: Readability and style changes.
+ * src/reader.c: Factoring: assign_named_ref function.
+ * src/scan-code.l: Factoring and style changes. Rename
+ parse_named_ref to parse_ref. Use "c-ctype.h" from gnulib.
+ Use "unsigned" type for variant index. Improve readablity.
+ * src/scan-gram.l: Change error messages and add comments.
+ * src/symlist.h: symbol_list_null: New function decl.
+ * src/symlist.c: symbol_list_null: Implement here.
+ * tests/named-refs.at: Adjust for new error messages.

+
+ scan-code: avoid compiler warnings
+ * src/scan-code.l (parse_named_ref): Use correct specifiers.

+
+ build: avoid concurrent extraction of calc++.
+ * examples/calc++/Makefile.am (calc.stamp): New.
+ Depend on it to create the sources of calc++ so that concurrent
+ builds don't launch several "extexi" in parallel.
+ Not only this is inefficient, this also builds incorrect sources
+ with several extractions mixed together.
+
+2009-06-29 Akim Demaille <demaille@gostai.com>
+
+ parse.error: fix.
+ * data/bison.m4: Move code related to specific variables after the
+ definition of the variable-maintaining macros so that we don't
+ "invoke" b4_percent_define_check_values before it is defined.
+

+
+ variables: parse.error
+
+ Implement, document, and test the replacement of %error-verbose
+ by %define parse.error "verbose".
+ * data/bison.m4 (b4_error_verbose_if): Reimplement to track the
+ values of the parse.error variable.
+ Make "simple" its default value.
+ Check the valid values.
+ * src/parse-gram.y: Use %define parse.error.
+ (PERCENT_ERROR_VERBOSE): New token.
+ Support it.
+ * src/scan-gram.l: Support %error-verbose.
+
+ * doc/bison.texinfo (Decl Summary): Replace the documentation of
+ %define error-verbose by that of %define parse.error.
+ * NEWS: Document it.
+
+ * tests/actions.at, tests/calc.at: Use parse.error instead of
+ %error-verbose.
+
+2009-06-27 Alex Rozenman <rozenman@gmail.com>
+
+ Implement support for named symbol references.
+ * src/parse-gram.y: Add new syntax (named_ref.opt).
+ * src/reader.c: Store named refs in symbol lists.
+ * src/reader.h: New argument for symbol_append and
+ action_append functions.
+ * src/scan-code.h: Add new field (named_ref) into
+ code_props data structure. Keeps named ref of midrule
+ actions.
+ * src/scan-code.l: Support for named refs in semantic
+ action code. New function 'parse_named_ref'.
+ * src/scan-gram.l: Support bracketed id.
+ * src/symlist.c: Store named refs in symbol lists.
+ * src/symlist.h: New field in symbol list: named_ref.
+ * src/named-ref.h: New file, a struct for named_ref.
+ * src/named-ref.cp: New file, named_ref_new function.
+ * src/local.mk: Add two new files.
+ * tests/testsuite.at: Include new test group:
+ * tests/named-refs.at: this new file.
+

+ hash: check insertion for memory exhaustion.
+ * src/uniqstr.c (uniqstr_new): New.
+
+2009-06-24 Akim Demaille <demaille@gostai.com>
+
+ variables: rename namespace as api.namespace.
+ Discussed in
+ http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00033.html
+
+ * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
+ New.
+ (b4_percent_define_use): New.
+ Use it where applicable.
+ * data/c++.m4: Replace uses of the variable "namespace" by
+ "api.namespace".
+ Default the latter to the former.
+ * doc/bison.texinfo (Decl Summary): Document "namespace" as
+ obsolete.
+ Document api.namespace.
+ Use @samp to document %define uses, keep @code for identifiers.
+ * NEWS: Likewise.
+ * tests/c++.at, tests/input.at: Test api.namespace instead of
+ namespace. (The tests passed with namespace.)
