- * Updated copyright to 2017.
- Sun Oct 23 16:38:05 PDT 2016 Ken Pizzini <ken@gnu.org>
- * dc/eval.c: dc_system() already eats up to (and including)
- a trailing newline, so don't fall-through in dc_evalstr()'s
- DC_SYSTEM case to DC_COMMENT's skip_past_eol() call,
- as that would unexpectedly require eating a second newline.
- Thanks to David José for noticing and reporting the bug.
- Thu Oct 20 03:11:43 PDT 2016 Ken Pizzini <ken@gnu.org>
- * doc/dc.texi: fix some typos.
- Mon Oct 17 00:28:50 PDT 2016 2016 Ken Pizzini <ken@gnu.org>
- * doc/dc.1, doc/dc.texi: document the new default-to-zero
- of the 'l' command.
- Mon Oct 17 00:02:11 PDT 2016 Ken Pizzini <ken@gnu.org>
- * doc/dc.1, doc/dc.texi: be more careful in specifying how
- the precision of the result of the "v" (square root)
- command is determined.
- Thanks to David José for pointing out that the old text
- underspecified this.
- Sun Oct 16 23:43:05 PDT 2016 Ken Pizzini <ken@gnu.org>
- * dc/stack.d: return a 0 (zero value; instead of reporting an error)
- for the "l" command when the named register stack is empty.
- Thanks to David José for the suggestion. (This is a useful default
- value, and make GNU dc more compatable with BSD dc and Bell Labs
- version 7 dc.)
- Wed Sep 28 13:24:50 PDT 2016 Ken Pizzini <ken@gnu.org>
- * dc/eval.c, doc/dc.1, doc/dc.texi: update copyright dates
- Sat Sep 24 16:04:01 PDT 2016 Ken Pizzini <ken@gnu.org>
- * dc/dc.c, dc/eval.c: yesterday's fix for 'Q' created a
- new bug for the 'q' command; this fresh (and simpler!)
- fix does the right thing. (Thanks again to Paul Rayner.)
- Fri Sep 23 22:49:17 PDT 2016 Ken Pizzini <ken@gnu.org>
- * dc/dc.c: don't prematurely exit from stack-unwinding 'Q'
- command
- * dc/eval.c: ensure that DC_FAIL API value does not
- collide with any internal dc_status code
- * doc/dc.1, doc/dc.texi: clarify that 'Z' command reports
- on digits in decimal representation in number (as opposed
- to ambiguous, perhaps "o"base, digits).
- * (Bugs reported by Paul Rayner; thanks.)
- Mon Feb 29 15:56:00 PST 2016 Phil Nelson <philnelson@acm.org>
- * Makefile.am, bc/Makefile.am: update to not include
- libmath.h in distribution.
- * configure.ac: update copyright with 2016
- Mon Feb 29 13:06:00 PST 2016 Phil Nelson <philnelson@acm.org>
- * bc/Makefile: Add $(LIBBC) as dependency to fbc so
- libmath.h gets correctly built. sbc also needed it.
- Mon Feb 29 12:05:00 PST 2016 Phil Nelson <philnelson@acm.org>
- * bc/util.c, bc.y: Fix two memory leaks submitted to
- Gentoo by Bruce Dubbs.
- Tue Jan 19 22:10:10 PST 2016 Phil Nelson <philnelson@acm.org>
- * bc/{execute.c, load.c, main.c, proto.h, scan.l, storage.c, util.c},
- lib/number.c: Update copyrights, remove old style function
- declarations, remove _PROTOTYPE macros, update to GPL V3.
- Various other code cleanups.
- Mon Jan 11 14:01:32 PST 2016 Ken Pizzini <ken@gnu.org>
- * doc/dc.texi: fix typo (reported by Avinash Sonawane)
- Mon May 11 16:40:31 PDT 2015 Ken Pizzini <ken@gnu.org>
- * dc/stack.c: catch the case of an empty value on top of
- a register stack (i.e., the stack entry is first created by
- an array store on a previously unallocated register)
- as a normal run-time error, rather than an abort() condition.
- (Bug reported by Hanno Böck, who found it during fuzz testing.)
- Mon Jan 26 22:30:00 PST 2015 Phil Nelson <philnelson@acm.org>
- * bc/execute.c, load.c, scan.l, storage.c: Extend input
- base to allow for base 36 with Z being the largest
- input digit. Now, ZZZZZ will be the largest 5 digit
- number given the allowable bases.
- Mon Jan 26 21:34:00 PST 2015 Phil Nelson <philnelson@acm.org>
- * various: updated copyright on all GPL licence comments.
- Mon Jan 19 00:03:05 PST 2015 Ken Pizzini <ken@gnu.org>
- * News: brought up-to-date for dc-1.07 release
- * README: bump relase number
- * bootstrap.sh: let the autotools give us as much guidance as they can
- * configure.ac: modernize, based on autotools' -Wall suggestions;
- update copyright years; GPL version 3; use URL to get copy of GPL,
- instead of snail-mail address; version bump (for both dc and bc);
- simplify the libedit/readline/flex cross-check logic
- * dc/eval.c: update copyright years
- Thu Nov 27 22:17:17 PST 2014 Ken Pizzini <ken@gnu.org>
- * dc/eval.c: dc_evalstr() incorrectly used len-1, to omit counting the
- closing ']', unconditionally, even when string parsing terminated
- prematurely (end-of-string reached before closing ']' was found).
- This is wrong in general, and painfully wrong when len==0.
- (Bug reported by Hanno Böck, who found it during fuzz testing.)
- Fri Oct 31 13:50:18 PDT 2014 Ken Pizzini <ken@gnu.org>
- * dc/eval.c: dc_evalstr() was inappropriately/prematurely returning
- when the top-of-stack was a number. (Bug reported by Saito Takaaki.)
- Sun Sep 7 15:20:29 PDT 2014 Ken Pizzini <ken@gnu.org>
- * dc/eval.c: the '!' command was incorrectly interacting with stdin
- rather than fp (the current input stream) when reading the
- shell command to be executed. (Bug reported by Dario Niedermann.)
- Sat Oct 26 14:54:37 PDT 2013 Ken Pizzini <ken@gnu.org>
- * doc/dc.1, doc/dc.texi: Updated copyright dates.
- Sat Oct 26 14:54:37 PDT 2013 Ken Pizzini <ken@gnu.org>
- * doc/dc.1, doc/dc.texi: Documented the "R" (rotate stack) command.
- Sat Oct 26 14:39:10 PDT 2013 Ken Pizzini <ken@gnu.org>
- * dc/dc-proto.h, dc/dc.c, dc/eval.c, dc/misc.c, dc/numeric.c,
- dc/stack.c, dc/string.c:
- Explicitly flush output, instead of requesting line buffering,
- as the user may be emitting a prompt (without a trailing newline)
- within an inferior process. Also, clean-up/simplify related code.
- Fri Jun 29 13:14:18 PDT 2012 Ken Pizzini <ken@gnu.org>
- * dc/eval.c dc/stack.c, dc/dc-proto.h:
- Implement 'R', general stack rotation command
- Thu Mar 7 21:55:47 PST 2013 Phil Nelson <phil@cs.wwu.edu>
- * configure.ac, bc/Makefile.am, dc/Makefile.am, lib/Makefile.am:
- Update automake definitions for newer versions of automake.
- Tested with version 1.13.1.
- Tue Nov 2 11:09:00 2010 Phil Nelson <phil@cs.wwu.edu>
- * bc/{bc.y, execute.c, load.c, main.c, proto.h, scan.l,
- util.c}: Add a bc_exit() routine that resets the editline
- state in one place to exit. Removed editline state reset
- in other places.
- Sun Mar 21 11:42:16 2010 Ken Pizzini <ken@gnu.org>
- * dc/eval.c: take a more nuanced approach to handling SIGINT
- Thu May 22 17:28:07 2008 Ken Pizzini <ken@gnu.org>
- * All: update copyright statements and license statements:
- the code is now released under GPL-3, and documentation
- under FDL-1.2.
- * configure.in, Makefile.am, bootstrap.sh; h/* lib/* gnulib/* m4/*:
- import portability code via gnulib-tools
- * bc/bc.y, bc/sbc.y, bc/execute.c, bc/load.c, bc/main.c, bc/proto.h,
- bc/scan.l, bc/util.c: detect, report (if possible), and exit with
- error if any I/O errors are encountered
- * doc/dc.texi: clean-up preamble (using more modern texinfo macros)
- Mon Sep 4 19:27:49 2006 Ken Pizzini <ken@gnu.org>
- * configure.in: re-factor how version numbers are handled; add errno.h
- and strtol() checks; add doc-texi-ver.incl output
- * bc/bcdefs.h: Prefer <string.h> over <strings.h>
- * bc/execute.c, bc/load.c, bc/main.c, bc/proto.h, bc/scan.l,
- bc/storage.c, bc/util.c, bc/warranty.c: De-lint some with "const"
- declarations, "static" declarations, and un-shadowing a few global
- variables and functions
- * dc/dc.c: add "static" keyword on flush_okay() function declaration,
- just for good hygene
- * dc/numeric.c: Reworked to avoid breaking C99 type-punning rules
- Wed Jun 14 08:21:17 2006 Ken Pizzini <ken@gnu.org>

- stop whining about the type punning
- * dc/dc.c (flush_okay): add "static" keyword as a matter of good
- coding hygene
- Sun Jun 11 21:40:37 2006 Ken Pizzini <ken@gnu.org>
- * doc/bc.1: strip release version information which is not being
- automatically kept up-to-date
- * doc/dc.1: don't capitalize Dc or DC
- Sun Jun 11 09:07:26 2006 Ken Pizzini <ken@gnu.org>
- * doc/bc.texi, doc/dc.texi, doc/texi-ver.incl.in, doc/Makefile.am:
- make version text in texinfo-based documentation auto-derive from
- configure.in
- * configure.in: update to use more modern automake/autoconf
- directives; factor out version numbers so that AC_SUBST and
- AC_OUTPUT kcan be used to create doc/texi-ver.incl
- * doc/Makefile.am: automake does (now) have a mechanism to
- auto-include declared man pages in the dist tarball, so
- remove FIXME block
- Sun Jun 11 03:04:18 2006 Ken Pizzini <ken@gnu.org>
- * lib/Makefile.am: testmul, specialnumber, multidigits.h are
- autogenerated by special request (only), and "make clean" should
- remove them
- * lib/testmul.c: CLOCKS_PER_SEC is typically a "long" value, so make
- test_time wide enough to hold it; add missing #include directives
- * lib/number.c: silly warning clean-up:
- + declare rt_warn() and rt_error() to take a CONST char* first
- argument
- + neither _bc_rec_mul() nor _bc_simp_mul() use the full_scale
- argument, so remove it in the function definitions and invocations
- + some C libraries define an index() function; use a different index
- variable name to avoid gratuitous namespace shadowing
- Sun Jun 4 13:56:58 2006 Ken Pizzini <ken@gnu.org>
- * doc/dc.texi: document new DC_LINE_LENGTH variable; mention
- traditional dc's handling of P with a numeric input
- * dc/dc.c (flush_okay, main): make code detecting and handling
- write errors cleaner
- Sun Jun 4 12:26:00 2006 Phil Nelson <phil@cs.wwu.edu>
- * bc/main.c: Make sure 3 is the minimum line length.
- * doc/bc.1, doc/bc.texi: Document the BC_LINE_LENGTH of 0 feature.
- Sun Jun 4 04:41:28 2006 Ken Pizzini <ken@gnu.org>
- * dc/dc.c (main): fflush() isn't enough: also check that fclose()
- does not return an error before exiting with EXIT_SUCCESS
- Sun Jun 4 04:15:15 2006 Ken Pizzini <ken@gnu.org>
- * dc/dc.c, dc/eval.c: detect, report (if possible), and exit with error
- if any I/O errors are encountered
- Sun Jun 4 02:27:41 2006 Ken Pizzini <ken@gnu.org>
- * bc/main.c, bc/util.c: allow a BC_LINE_LENGTH of zero as a
- special-case, meaning "don't ever wrap lines"
- * dc/numeric.c, configure.in: add support for a DC_LINE_LENGTH
- variable, with a value of zero meaning "don't ever wrap lines"
- Fri May 5 18:45:17 2006 Ken Pizzini <ken@gnu.org>
- * dc/dc.c (try_file): S_ISREG() test was inverted! :-(
- (how very embarrassing)
- * configure.in: the "if test" -> "case" conversion in the last commit
- translated the handling of flex incorrectly; fixed
- * src/scan.l: readline versions 4.2 and up give their own prototype
- for readline() in readline.h, which conflicts with the one that is
- in scan.l, so just do without the prototype in scan.l (if someone
- needs to backport to a very old version of readline, they should be
- able to handle adding the prototype back in themselves)
- * doc/bc.texi: use of @var{} in @item causes capitalization on output,
- which is wrong, and furthermore the use of @var{} for e() and j() is
- also inconsistent with how the other math functions are formatted
- Sat Apr 29 05:02:15 2006 Ken Pizzini <ken@gnu.org>
- * configure.in: The "true" branch of AC_ARG_WITH needed to
- be conditionalized on the value of $withval (thanks to Mike
- Frysinger of Gentoo for pointing this out); prefer using
- "case" over "if test" in shell string-match conditionals;
- make use of AC_HELP_STRING; added copyright block; clean
- out old "dnl"'d directives
- Sat Apr 29 04:02:23 2006 Ken Pizzini <ken@gnu.org>
- * dc/dc.c (try_file): fix typo in S_ISFIFO conditional
- * doc/bc.1, doc/bc.texi, doc/dc.1, doc/dc.texi: make some
- formatting clean-up (minor)
- Wed Apr 26 15:38:32 2006 Ken Pizzini <ken@gnu.org>
- * dc/dc.c (try_file): rework special-file detection so that
- friendlier error messages can be given for the most common
- error of this class (i.e., the "dc directory" typo).
- Thu Apr 20 17:45:46 2006 Ken Pizzini <ken@gnu.org>
- * configure.in: Newer versions of flex (such as ver. 2.5.33)
- don't seem to like an argument of "-I8" anymore ("option `I'
- doesn't allow an argument"), so split that into "-I -8".
- Wed Mar 29 05:09:14 2006 Ken Pizzini <ken@gnu.org>
- * dc/string.c, dc/misc.c, dc/stack.c, dc/dc.c, dc/eval.c, dc/array.c:
- Make splint (http://www.splint.org/) happier by making all
- comparisons to 0 and NULL explicit, and adding some explicit casts
- that aren't strictly necessary. (But I'm omitting from this commit
- various splint annotations that just serve to make the code ugly.)
- Tue Mar 28 13:36:00 2006 Phil Nelson <phil@cs.wwu.edu>
- * bc/util.c: Move code so size checks are before use.
- * doc/bc.1: Quote .IP argument.
- Tue Mar 28 12:09:38 2006 Ken Pizzini <ken@gnu.org>
- * dc/dc.c (try_file): Added file type detection to ignore some
- special files (particularly directories and block files), because
- several people have asked that a typo for "cd" not fail silently.
- * configure.in: add detection of fstat() to determine how the
- above detection should be implemented.
- Wed Mar 15 9:50:00 2006 Phil Nelson <phil@cs.wwu.edu>
- * lib/getopt.c: Added a define to disable/enable
- gettext support. May need to be deleted later
- when gettext is fully supported.
- Mon Mar 13 13:57:00 2006 Phil Nelson <phil@cs.wwu.edu>
- * bc/bc.y: Remove second call to lookup() in a rule.
- Removes a free'd twice bug.
- Sat May 28 05:42:01 2005 Ken Pizzini <ken@gnu.org>
- * doc/dc.1, doc/dc.texi: add verbage about the need to use

- Fri May 20 ??:??:?? 2005 Ken Pizzini <ken@gnu.org>
- * lib/getopt.c, lib/getopt1.c: Update to more recent versions.

- * dc/eval.c: ignore trailing comments in tail-recursion detection
- * dc/eval.c, doc/dc.texi: finally fix dc to trap interrupts,
- aborting pending macros but not exiting
- Fri May 27 03:37:30 2005 Ken Pizzini <ken@gnu.org>
- * dc/numeric.c: Address Debian bug #221781: values exceeding
- a C "long" don't play well with k/i/o/a/Q/:/; commands.
- Adding a diagnostic, and returning a "more bogus" value than
- zero, for this situation.
- Thu May 26 09:03:57 2005 Ken Pizzini <ken@gnu.org>
- * dc/eval.c:
- 1) fix tail recursion to also work for 'x' and '?' commands
- 2) fix tail recursion to ignore trailing spaces in the current
- invocation string when determining if tail recursion is
- appropriate
- 3) remove a couple of misleading and/or meaningless comments
- 4) add documentation for stdin_lookahead, since the code is far
- from transparent about its purpose and usage
- 5) simplify ibase conditional by rearranging branches
- Wed May 25 21:20:08 2005 Ken Pizzini <ken@gnu.org>
- * dc/array.c dc/dc-proto.h dc/dc-regdef.h dc/dc.c dc/dc.h
- dc/eval.c dc/numeric.c: whitespace cleanup
- Wed May 25 19:48:26 2005 Ken Pizzini <ken@gnu.org>
- * COPYING COPYING.LIB dc/dc-proto.h dc/dc-regdef.h dc/dc.h
- dc/array.c dc/dc.c dc/eval.c dc/misc.c dc/numeric.c dc/stack.c
- dc/string.c doc/dc.1 doc/dc.texi:
- update FSF address in copyright notices
- Wed May 25 19:39:46 2005 Ken Pizzini <ken@gnu.org>
- * dc/stack.c: If a register is used for an array, its corresponding
- stack could be auto-created in the DC_UNINITIALIZED state; handle
- this situation gracefully. Thanks to Ben Collerson
- (http://bur.st/~benc/) for the bug report.
- Wed Dec 31 07:26:00 2003 Phil Nelson <phil@cs.wwu.edu>
- * Makefile.am: add depcomp

- * bc/*: consistent copyright
- Fri May 9 21:52:46 2003 Ken Pizzini <ken@gnu.org>
- * dc/dc-proto.h dc/dc.c dc/eval.c: add tail-recursion optimization
- * dc/numeric.c: clean up handling of conditional includes/defines;
- editorial fix to comment; trivial (indentation, mostly) clean-up of
- out_char() function [gratuitious; commit was accidental and I'm
- adding this note to a replacement log message]
- * dc/misc.c: fixed spelling and grammatical errors in comment
- * dc/dc-regdef.h: simplify the handling of UCHAR_MAX/DC_REGCOUNT
- defaults
- Thu Apr 17 16:25:35 2003 Phil Nelson <phil@cs.wwu.edu>

- Fri Jan 19 10:33:13 2001 Phil Nelson <phil@cs.wwu.edu>
- * bc/{main.c,execute.c}: Don't use stdio calls in signal

- Mon Jul 31 07:01:42 2000 Ken Pizzini <ken@gnu.org>
- * dc/numeric.c: use of the "n" command can cause a number to be printed
- without a trailing newline, which would cause the column counter to
- fail to be reset and result in inappropriately wrapped numeric outputs.
- Fixed by always clearing the column counter before outputting each number.
- * dc/stack.c: if a stack is used without ever using the correspondingly
- named register, it is perfectly legitimate for the register to be
- uninitialized; added an "else if" to handle this case without aborting.

- * h/version.h: dc is now up to version 1.1.5.
- * dc/eval.c, dc/numeric.c, doc/dc.texi, doc/dc.1: once again
- changed the behavior of the 'P' command with a numeric argument
- to make it more general. It now dumps out the *whole* number
- (or rather, the whole of its positive integer portion) as a
- byte stream. (For small values this is still the same as 'aP'.)
- * dc/dc-proto.h, dc/dc.h, dc/eval.c, dc/misc.c, dc/numeric.c,
- dc/stack.c, dc/string.c: Changed most uses of dc_boolean to
- either dc_discard or dc_newline, and instances of DC_TRUE and
- DC_FALSE to appropriate instances of DC_TOSS, DC_KEEP, DC_NONL,
- or DC_WITHNL so that the code self-documents a little better.
- Sun Jan 4 15:39:46 PST 1998 Ken Pizzini <ken@halcyon.com>
- * dc/eval.c, doc/dc.texi, doc/dc.1: Changed the functionality
- of the 'P' command, and added the 'n' command. Due to
- a quirk of the implementation of traditional dc, some
- people have come to expect that the 'P' command on a
- numeric argument in the range of 1 to 99 should output
- the corresponding character, despite the fact that this
- usage can have very weird results for numbers outside
- that range. This functionality is why the 'a' command
- was introduced last March, but people really want it to
- "just work" without needing to use the 'a' command.
- Bowing to this demand, the 'P' command now does the
- equivalent of "aP" if the argument is numeric, and the
- 'n' command has been added to support the previous
- functionality of the 'P' command.
- * dc/misc.c, dc/eval.c, dc/stack.c, dc/dc-proto.h:
- Changed prototype for dc_print(). It now additionally
- takes two flags, newline_p and discard_p, which it
- passes through to dc_out_num() and dc_out_str() as
- needed.
- * h/version.h: dc is now up to version 1.1.4.
- Sat Sep 27 13:48:53 1997 Ken Pizzini <ken@halcyon.com>
- * h/version.h: dc is now up to version 1.1.3.
- * dc/stack.c, dc/array.c, dc/dc-proto.h, doc/dc.texi, doc/dc.1:
- It has come to my attention that, though undocumented,
- traditional dc stacked its arrays in parallel with the
- stacking of simple registers. I have now duplicated
- this functionality.
- * dc/dc.c, configure.in: line-buffer dc's output if setvbuf()
- is supported. This was requested to simplify using dc as
- an inferior process under emacs.
- Fri Sep 26 19:56:15 1997 Ken Pizzini <ken@halcyon.com>
- * dc/dc.c: fixed bug reporting address for --help.

- library is loaded, redefinition of any math library function
- will not cause the other functions to quit working correctly.
- Before this change, redefining a(x) would cause s(x) and c(x)

- working.
- Wed Jul 1 14:35:29 1992 Phil Nelson (phil at cs.wwu.edu)
- * (libmath.b) Changed the calculation of scale for computing
- e(x) and l(x). This provides a little more accuracy in the

- with /usr/include/math.h. Changed all references to math.h
- to libmath.h in all files.
- * (configure) Changed the test for long strings accepted by
- cc to not include libmath.h and thus not need to distribute
- a file that is generated by the system.

- lower case.
- Tue Mar 3 10:16:07 1992 Phil Nelson (phil at cs.wwu.edu)

- report illegal characters in a more readable output format.
- * (bc.1) Added the exclusion of NUL characters from strings in
- the "differences" section and updated date of last change.
- * (const.h) Changed BC_MAX_SEGS to 16.
- Mon Jan 6 14:20:02 1992 Phil Nelson (phil at cs.wwu.edu)

- size for bases greater than 16. e.g. For base 1000, each
- "digit" is a three digit number.
- * (Makefile) Added the "8" flag to get an 8 bit scanner.
- * (scan.l) Changed "char *" to "unsigned char *" to match the
