Raw Blame History

Fri Apr 17 10:40:59 1998 Phil Nelson <phil@cs.wwu.edu>
* bc/main.c: Enable readline only if interactive.
Thu Apr 16 16:49:22 1998 Phil Nelson <phil@cs.wwu.edu>
* bc/configure.in: Tweeking of AM_PROG_LEX and associated
special case goo for solaris.
Sat Mar 28 21:43:18 1998 Phil Nelson <phil@cs.wwu.edu>
* bc/Makefile.am: Added "YFLAGS = -d" to get bc.h to build properly.
Mon Mar 9 12:54:42 PST 1998 Ken Pizzini <ken@halcyon.com>
* doc/dc.texi, doc/dc.1: correct some documentation bugs.
Sun Mar 8 23:56:24 PST 1998 Ken Pizzini <ken@halcyon.com>
* dc/numeric.c: eliminate superfluous variable from dc_dump_num();
annotate unused parameters in dc_add() and dc_sub().
* h/version.h: change dc version number to 1.2 for release.
Sun Mar 8 21:13:50 1998 Phil Nelson <phil@cs.wwu.edu>
* bc/main.c: Applied patch from Ken Pizzini to force line
mode buffering on stdout.
Tue Jan 6 09:15:04 PST 1998 Ken Pizzini <ken@halcyon.com>
* 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.
* doc/dc.1, doc/dc.texi: corrected documentation of the maximum
admissible input base.
* doc/dc.texi: corrected sample code equivalence for the | command.
* lib/number.c: added a warning for non-zero scale in the base
for bc_raisemod().
Fri Sep 26 18:15:31 1997 Ken Pizzini <ken@halcyon.com>
* dc/eval.c, doc/dc.1, doc/dc.texi: added !=, !<, and !> commands.
* dc/eval.c: eliminated double-free in 'a' command.
* dc/dc.c: changed placment of check for filename "-" so that
"-f -" will work.
* h/version.h: updated dc version to 1.1.2.
Thu Sep 18 17:41:10 1997 Ken Pizzini <ken@halcyon.com>
* dc/eval.c: fixed off-by-one error for Q and q commands.

Thu May 22 08:24:08 1997 Phil Nelson <phil@cs.wwu.edu>
* lib/number.c(bc_sqrt): Fixed a bug that computed 0 for sqrt
of most numbers less than .000001.
Thu May 1 10:41:38 1997 Phil Nelson <phil@cs.wwu.edu>

of the memset call to make sure it zeroed all the
storage.
Fri Apr 18 13:58:56 1997 Phil Nelson <phil@cs.wwu.edu>

call. arg_str produced them in the reverse order. This
eliminated the need for the "comma" argument to arg_str, which
was removed.

* (const.h, bc.y, util.c) Added code so that when the math
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)
to quit working and redefining s(x) would cause c(x) to quit
working.

* (libmath.b) Changed the calculation of scale for computing
e(x) and l(x). This provides a little more accuracy in the
last digit at the expense of a little speed.
* (Test/checklib.b) Changed tests to be parameterized and test
more values.
Thu Jun 25 09:22:59 1992 Phil Nelson (phil at cs.wwu.edu)
* (configure) changed the script from looking in the
include directory for a .h file to asking cc (gcc) to
find the .h file. This will allow better detection
of include files available to the C compiler.
Wed Jun 24 22:11:37 1992 Phil Nelson (phil at cs.wwu.edu)
* (bc.y) Added a warning for the "last" variable.
* (scan.l) Added code to allow for a single dot (.) to be the
same as the variable "last". This is not a "standard" feature,
but is provided for those who want it.
* (Install) Documented the new define for dot (.).
* (bc.1) Documented the use of dot (.) for "last".
* (Makefile) Added an easy method for adding extra defines for
use during the compile. Set DOT_IS_LAST as a standard
extra define.
* (number.c) Changed the code for sqrt for better speed.
Mon Jun 22 21:47:05 1992 Phil Nelson (phil at cs.wwu.edu)
* Changed the name of math.h to libmath.h to avoid conflict
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.
* (Makefile) Changed PREFIX, BINDIR, LIBDIR, and MANDIR to
lower case.
Tue Mar 3 10:16:07 1992 Phil Nelson (phil at cs.wwu.edu)
* (main.c) Added missing } at line 140.
* (version.h) Changed date of version 1.02 to March 3, 1992.
Mon Feb 3 16:07:57 1992 Phil Nelson (phil at cs.wwu.edu)
* (version.h) Updated version number and date.
* (bc.1) Added a new "VERSION" section.
Wed Jan 29 14:13:55 1992 Phil Nelson (phil at cs.wwu.edu)
* (execute.c) Removed the setjmp and longjmp calls that may have
caused some problems with interrupted programs.
Thu Jan 16 17:08:16 1992 Phil Nelson (phil at cs.wwu.edu)
* (Makefile) Changed install to install the manual.
Wed Jan 8 13:23:42 1992 Phil Nelson (phil at cs.wwu.edu)
* Change all copyright notices to include 1992.
* (load.c) Added termination to "load_code" to ignore code
after an error has been found.
* (scan.l) Changed the check for NUL characters in STRING tokens
(before the close quote) to work correctly. Also added code to
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)
* (number.c) Changed the out_num routine to use a correct field
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
declaration of yytext for the 8 bit scanner. Also added code
to detect the null character in strings and generate an error.
Sat Jan 4 20:32:20 1992 Phil Nelson (phil at cs.wwu.edu)
* (const.h) Changed BC_BASE_MAX to INT_MAX to allow more bases!
Mon Dec 30 21:47:28 1991 Phil Nelson (phil at cs.wwu.edu)
* (main.c) Fixed the bug that loaded the math library before
every file.
* (bc.y) Removed some type declarations that duplicated token
definitions so it could be run through bison.
* (load.c) Added a check for maximum code size.
* (Makefile) Added a prefix for LIBDIR and BINDIR so it can be
changed easily.
Mon Nov 25 13:11:17 1991 Phil Nelson (phil at cs.wwu.edu)
* Changed version number in version.h to 1.01 with current date.
* Changed LIBFILE definition in Makefile.
* Added a recursive function example to bc.1.
Sun Nov 24 21:24:01 1991 Phil Nelson (phil at cs.wwu.edu)
* Changed the Makefile to make sure configure is run first.
Added the $(CC) the configure call. Moved some defines
toward the front of the Makefile to make sure they are
read by installers. Also added SUBDIRS variable and updated
the GNU distribution to include the subdirectories. Included
math.h in the distribution for use by configure. Included
ChangeLog in the distribution.
* Split the README into README and Install. Changed Install
to have current information. Documented the STRINGS_H define.
Updated the version number in README.
* Added a check for <strings.h> in configure.
Fri Nov 22 15:06:32 1991 Phil Nelson (phil at cs.wwu.edu)
* Changed configure to check for varargs.h first. Also, added
checks to see if long strings (math.h) are accepted by the
C compiler. Also added parameters to configure.
* Deleted #include <sys/types.h> from proto.h. Also made only
ANSI C compilers include <stdlib.h>.
* Changed the Makefile to have the install bin directory be
/usr/local/bin and the install lib directory be /usr/local/lib.
* Changed some files in the Test directory to eliminate the
<op>= form that some older bcs don't like.
* Made some small corrections in bc.1.
Tue Oct 29 10:06:32 1991 Phil Nelson (phil at cs.wwu.edu)
* Called current version 1.00.
* Submitted GNU bc-1.00 to comp.sources.reviewed
