The previous commit, which turns into a warning what used to be an
error:
%printer {} foo;
%%
exp: '0';
has two shortcomings: the warning is way too long (foo is reported
to be useless later), and besides, it also turns into a warning much
more serious errors:
%printer {} foo;
%%
exp: foo;
Reduce the amount to warnings in the first case, restore the error in
the second.
* src/symtab.h (status): Add a new inital state: undeclared.
* src/symtab.c (symbol_new): Initialize to undeclared.
(symbol_class_set): Simplify the logic of the code that neutralize
the "redeclared" warning after the "redefined" one.
(symbol_check_defined): "undeclared" is also an error.
* src/reader.c (grammar_current_rule_symbol_append): Symbols appearing
in a rule are "needed".
* src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
An unknown symbol appearing in a %printer/%destructor is "used".
* src/reduce.c (nonterminals_reduce): Do not report as "useless" symbols
that are not used (e.g., those that for instance appeared only in a
%printer).
* tests/input.at (Undeclared symbols used for a printer or destructor):
Improve the cover the cases described above.
We used to raise an error if a symbol appears only in a %printer or
%destructor. Make it a warning.
* src/symtab.h (status): New enum.
(symbol): Replace the binary "declared" with the three-state "status".
Adjust dependencies.
* src/symtab.c (symbol_check_defined): Needed symbols are an error,
whereas "used" are simply warnings.

In order to improve the testing of %defines, which exports the
interface of the generated parser, change the calc.at tests so that
when %defines is passed, main will be in another compilation unit. It
loads the generated header.
* tests/calc.at (AT_CALC_MAIN): New.
Includes the definition of the global variables.
Therefore, now declare them from the %requires section of the parser.
Adjust to yydebug and yyparse being renamed by %name-prefix.
Using http://github.com/lyda/misspell-check, massage its
output into sed commands to perform the suggested changes.
Initially, I filtered out the THRU->Through changes, because
that failed to retain capitalization in the grammar token.
Instead, do this manually, beforehand:
sed -i s/THRU/THROUGH/ tests/existing.at
git ls-files|misspellings -f -|perl -nl \
-e '/^(.*?)\[(\d+)\]: (\w+) -> "(.*?)"$/ or next;' \
-e '($file,$n,$l,$r)=($1,$2,$3,$4); $q="'\''"; $r=~s/$q/$q\\$q$q/g;'\
-e 'print "sed -i $q${n}s!$l!$r!$q $file"'|bash
Currently the test 248, "parse-gram.y: LALR = IELR", fails
BISON_TEST_XML is set.
* tests/local.at (AT_BISON_CHECK_XML): Belt: Save/restore files.
* tests/regression.at (parse-gram.y: LALR = IELR): Suspenders: Don't
rely on expout.
Each one of these changes suffices.
Some of our macros play with expout and other Autotest special files,
which may break their callers (e.g., currently TESTSUITEFLAGS='248
BISON_TEST_XML=1' fails).
There is already some support for this. Expand it to be ready to use
it elsewhere.
* tests/local.at (AT_RESTORE_SPECIAL_FILES, AT_SAVE_SPECIAL_FILES)
(at_save_special_files, at_restore_special_files): New.
