1a9e39f116 (braces_level): Now auto, not static. 
Initialize to zero if the compiler is being picky.
(INITIAL): Clear braces_level instead of incrementing it.
(SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
as POSIX 1003.1-2001 requires.

48e28efa9e (IF_LINT): New macro, taken from coreutils. 2002-11-05 23:42:51 +00:00

29c017256a * src/scan-gram.l: When it starts with `%', complain about the 
whole directive, not just that `invalid character: %'.

c4d720cdbb * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid 
clashes.
* src/scan-gram.l: Use ['] instead of ['] to pacify
font-lock-mode.
Use complain_at.
Use quote, not quote_n since LOCATION_PRINT no longer uses the
slot 0.

45a8a65dee (get_merge_function, grammar_current_rule_check): 
Use consistent diagnostics for reporting type name clashes.
Quote the types with <>, for consistency with Yacc.

d8d3f94a99 Revamp to fix POSIX incompatibilities, to count columns correctly, and 
to check for invalid inputs.

Use mbsnwidth to count columns correctly.  Account for tabs, too.
Include mbswidth.h.
(YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
(extend_location): New function.
(YY_LINES): Remove.

Handle CRLF in C code rather than in Lex code.
(YY_INPUT): New macro.
(no_cr_read): New function.

Scan UCNs, even though we don't fully handle them yet.
(convert_ucn_to_byte): New function.

Handle backslash-newline correctly in C code.
(SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
(eols, blanks): Remove.  YY_USER_ACTION now counts newlines etc.;
all uses changed.
(tag, splice): New EREs.  Do not allow NUL or newline in tags.
Use {splice} wherever C allows backslash-newline.
YY_STEP after space, newline, vertical-tab.
("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).

(letter, id): Don't assume ASCII; e.g., spell out a-z.

({int}, handle_action_dollar, handle_action_at): Check for integer
overflow.

(YY_STEP): Omit trailing semicolon, so that it's more like C.

(<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
as well as \000.  Check for UCHAR_MAX, not 255.
Allow \x with an arbitrary positive number of digits, as in C.
Check for overflow here.
Allow \? and UCNs, for compatibility with C.

(handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
with quote slot used by complain_at.

Paul Eggert
397477b4e9 Don't include quote.h; not needed. 
(get_merge_function): Reword warning to be consistent with type clash
diagnostic in grammar_current_rule_check.
 2002-11-03 07:49:40 +00:00
Paul Eggert
01cfa69791 (prepare_symbols): When printing token names, escape "[" as "@<:@" and 
likewise for "]".
 2002-11-03 06:41:59 +00:00
Paul Eggert
3fbf949b82 (errno): Remove declaration, as we are now assuming C89 or better, and 
C89 guarantees errno.
 2002-11-03 06:16:55 +00:00
Akim Demaille
56100c60da * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only 
#if.
 2002-10-30 08:31:24 +00:00
Paul Eggert
30ba05f239 (output_skeleton): Use xfclose rather than fclose and ferror. xfclose 
now checks ferror.
 2002-10-30 06:20:02 +00:00
Paul Eggert
e63ee1f16c (xfclose): Return void, not int, since it always returned zero. 
Report I/O error if ferror indicates one.

Akim Demaille
b526ee6116 * src/output.c (output_skeleton): Don't disable M4sugar comments 
too soon: it results in comments being expanded.
* data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
first output.
 2002-10-24 11:40:27 +00:00

f6d0c2394c (main): With --trace=time, report times even if a non-fatal error 
occurs.  Formerly, the times were reported in some such cases but not
in others.
 2002-10-23 18:41:43 +00:00
Paul Eggert
f956c304c5 (reader): Just return if a complaint has been issued, 
instead of exiting, so that 'main' can report times.
 2002-10-23 18:41:04 +00:00
Akim Demaille
27b0ffea3e * src/system.h: Include sys/types.

Paul Eggert
e95aed631d (main): Use return to exit, undoing yesterday's change. 
The last OS that we could find where this wouldn't work is
SunOS 3.5, and that's too old to worry about now.

Paul Eggert
0ae6073a18 (warning_issued): Renamed from warn_message_count,

a4b6efd473 (getargs): When there are too few operands, report the last one. When 
there are too many, report the first extra one.  This is how diffutils
does it.
