2.12.7.1 is the latest stable version. for darwin use
${COMPILER_INCLUDE_DIRS} to find include dirs since
/usr/include may not be there. also, we want INCDIR
to point to the system includes, but we want CALC_INCDIR
to point at ${PREFIX}/include/calc. minor updates to Makefile
patch to do this.
2.12.4.13 to 2.12.7.1 changes from the calc maintainer's CHANGES file:
The following are the changes from calc version 2.12.7.1 to date:
Corrected CHANGES notes that were mixed up for TAB, VT, CR &
NL. The code in 2.12.7.0 is correct. The CHANGE notes should
have read:
The following is a partial list of escape sequences recognized
in strings and in printf formats:
\a audible bell byte 0x07 in ASCII encoding
\b backspace byte 0x08 in ASCII encoding
\f form feed byte 0x0c in ASCII encoding
\n newline byte 0x0a in ASCII encoding
\r return byte 0x0d in ASCII encoding
\t tab byte 0x09 in ASCII encoding
\v vertical tab byte 0x0b in ASCII encoding
Sorry!
The following are the changes from calc version 2.12.6.10: to 2.12.7.0:
Added a patch to replaces the manual search for include files
in $(INCDIR) in the have_*.h targets with compiler invocations.
Thanks goes to Helmut Grohne (helmut at subdivi dot de) who
implemented the patch and posted it to the Debian bug tracker
and Martin Buck (m at rtin-buck dor de) for forwarding it to us.
The check_include make rule was fixed to not assume /usr/include.
The qprintnum() function now takes outdigits as a 3rd argument.
Most of the time, this 3rd argument is just conf->outdigits.
But when it comes to the experimental '%g', this value can
change. This avoids having to modify conf->outdigits.
Fixed a problem where gcc complains about E_FUNC not being defined
for Linux systems as reported by Martin Buck (m at rtin-buck dor de).
Updated the help files help/config, help/display, help/epsilon,
help/fprint, help/printf, and help/strprintf to give more
examples of how display digits and epsilon precision interact
with displaying values.
Added more information about %g in the help file help/printf.
The '\a' is now recognized in a printf format string as the
single byte audible bell character (byte 0x07 in ASCII encoding).
The following is a partial list of escape sequences recognized
in strings and in printf formats:
\a audible bell byte 0x07 in ASCII encoding
\b backspace byte 0x08 in ASCII encoding
\f form feed byte 0x0c in ASCII encoding
\n newline byte 0x0a in ASCII encoding
\r return byte 0x0d in ASCII encoding
\t tab byte 0x09 in ASCII encoding
\v vertical tab byte 0x0b in ASCII encoding
The following are the changes from calc version 2.12.6.9 to 2.12.6.9:
Fixed a number of core dump bugs related to the calculation of
tan(), cot(), sec(), csc(), tanh(), coth(), sech(), and csch(),
asin(), acos(), asinh(), acosh(), where when a call to an
underlying function produced an invalid value. Thanks goes to
github user wuxiuheng for reporting this problem.
A number of trigonometric and hyperbolic functions that incorrectly
returned E_LOGINF, now return a new error code that is more
specific to the trigonometric or hyperbolic function. The
following is a list of these new error codes: E_TAN3 E_TAN4
E_COT3 E_COT4 E_SEC3 E_CSC3 E_TANH3 E_TANH4 E_COTH3 E_COTH4
E_SECH3 E_CSCH3 E_ASIN3 E_ACOS3 E_ASINH3 E_ACOSH3 E_ATAN3 E_ACOT3
E_ASEC3 E_ACSC3 E_ATANH3 E_ACOTH3 E_ASECH3 E_ACSCH3.
Added regression tests 3729 thru 3732 to test E_TAN3, E_COT3,
E_SEC3 and E_CSC3 respectively.
Added experimential %g printf (and strprintf) format implementation
based on pull request from github user 10110111.
Made exterimental changes to macOS builds to not require use of
/usr/include. The INCDIR for macOS uses:
INCDIR= $(shell xcrun --show-sdk-path --sdk macosx)/usr/include
to determine the upper path of the /usr/include directory for macOS.
In some rare cases, the Darwin target seems to not automatically detected.
If you are running under macOS, and that happens, you can force
the target to be Darwin:
# for macOS users only, force the target to be darwin
#
make target=Darwin clobber
make target=Darwin all
make target=Darwin chk
make target=Darwin install
The following are the changes from calc version 2.12.6.6 to 2.12.6.8:
For historical purposes, in lucas.cal, gen_v1(1, n) always returns 4.
Fixed some compiler warnings, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Added work around for a gcc warning bug, thanks to a report by Mike
<michael dot d dot ince at gmail dot com>.
Fixed errors in various help files such as:
mat randbit seed srandom types
Removed the MAXSTRING symbol because it was no longer used by calc.
Increased HIST_SIZE (depth of the history stack) from 10k to 32k.
Increased TTYSIZE (reallocation size for terminal buffers) from 100 to 8191.
Increased MAXDEPTH (maximum depth of input stack) from 10 to 255.
Increased interactive input buffer size from 1024 to 256k. This has the
effect of increasing the maximum length of an input line from a tty.
This helps with an interactive bug that was reported by Ruslan Kabatsayev
(b7 dot 10110111 at gmail dot com).
The calc man page indicates that -d also disables the printing of the
leading tilde.
Added information to "help command" about how to silence messages
while reading calc resource files.
Fixed an error message buffer overflow thanks to a report by
Frank Peters <nlp at northernlightsphoto dot biz>.
Replaced all use of the C funcion sprintf() with snprintf().
Replaced all use of the C funcion vsprintf() with vsnprintf().
Replaced all DONT_HAVE_VSPRINTF with DONT_HAVE_VSNPRINTF.
Replaced all Makefile var ${HAVE_VSPRINTF} with ${HAVE_VSNPRINTF}.
The following are the changes from calc version 2.12.6.4 to 2.12.6.5:
Fixed warning about undefined operations involving the qlink(q)
macro by replacing that macro with an inline-function. Thanks goes
to David Haller <dnh at opensuse dot org> for this fix.
NOTE for Windows 10 users: Pavel Nemec <pane at seznam dot cz>
reported that calc version 2.12.6.4 has been successfully
compiled, installed and running on Windows 10. See README.WINDOWS
for more details.
The following are the changes from calc version 2.12.6.1 to 2.12.6.3:
Improved gen_v1(h,n) in lucas.cal to use an even faster search method.
Improved are checking in lucas.cal. In particular both h and n must be
integers >= 1. In the case of both rodseth_xhn(x, h, n) and gen_v1(h, n)
h must be odd.
Fixed an C code indenting issue that was reported by Thomas Walter
<th dot walter42 at gmx dot de> in zfunc.c.
Fixed a man page warning about ./myfile where the leading dot
was mistook for an nroff macro. Thanks goes to David Haller
<dnh at opensuse dot org> for providing the patch.
Improved gen_v1(h,n) in lucas.cal for cases where h is not a
multiple of 3. Optimized the search for v(1) when h is a
multiple of 3.
Fixed a Makefile problem, reported by Doug Hays <doughays6 at gmail
dot com>, where if a macOS user set BINDIR, LIBDIR, CALC_SHAREDIR
or INCDIR in the top section, their values will be overwritten by
the Darwin specific section.
The following are the changes from calc version 2.12.6.0 to 2.12.6.0:
Added the makefile variable ${COMMON_ADD} that will add flags
to all compile and link commands. The ${COMMON_ADD} flags are
appended to both ${COMMON_CFLAGS} and ${COMMON_LDFLAGS}. This
facility is available to nearly all platforms except those with
very old make commands that do not understand the += operator.
Example on macOS (Darwin), one may invoke clang's -fsanitize
facility by:
make clobber all \
COMMON_ADD='-fsanitize=undefined -fsanitize=address'
Another example. To force C warnings to be treated as errors:
make COMMON_ADD='-Werror'
Created a GitHub repository for calc:
https://github.com/lcn2/calc
NOTE: The calc GitHub repository represents the an active
development stream. While an effort will be made to keep
the master branch of the calc GitHub repository in working
order, that tree may be unstable. Those wishing for more
reliable releases use releases found at calc mirror sites:
http://www.isthe.com/chongo/tech/comp/calc/calc-mirror.html
IMPORTANT NOTE:
On 2017 June 05, the calc GitHub history was re-written.
Anyone who was tracking the calc "pre-release" on GitHub prior
to version 2.12.6.0 should do a:
git reset --hard origin/master
git cleanup -f
Or you may just want to start over:
rm -rf calc
git clone https://github.com/lcn2/calc.git
Sorry about that. The previous GitHub repository was an useful
experiment. Based on what we learned, we decided to rebuild it.
Renamed README to README.FIRST. Added README.md for the
GitHub repository.
Fixed reading from standard input (stdin) when -p is given on
the command line. This now prints hello:
echo hello | calc -p 'stdin = files(0); print fgetline(stdin);'
Added more debugging related to stdin when bit 4 of calc_debug
is set (e.g., running calc with -D16).
Updated the calc(1) man page and 'help file' to explain about
reading from standard input (stdin).
Added some clarifying remarks for 'help ptest' explaining that
the ptest builtin can return 1 is some cases where the test
value is a pseudoprime.
Removed duplicate copyright comments from the help/builtin that
is built.
Fixed a number of typos in the CHANGES file.
The following are the changes from calc version 2.12.5.4 to 2.12.5.6:
Recompile to match current RHEL7.2 libc and friends.
Added fix by Alexandre Fedotov <fedotov at mail dot desy dot de>
to prepend ${T} in front of the CALCPATH path components
${CALC_SHAREDIR} and ${CUSTOMDIR}. Add ${T} in front of ${HELPDIR}
and ${CUSTONHELPDIR} when making conf.h.
Improved the jacobi help page.
Rewrote gen_v1() in the lucas.cal resource file using the method
based on a paper:
"A note on primality tests for N = h*2^n-1", by Oystein J. Rodseth,
Department of Mathematics, University of Bergen, BIT Numerical
Mathematics. 34 (3): pp 451-454.
http://folk.uib.no/nmaoy/papers/luc.pdf
The improved gen_v1() function is capable of returning a value
for all valid values of h and n. As a result, the trial tables
used by gen_v1() have been changed to a short list of values
to try, in order ot likelyhood of success, before doing an
exhaustive search for a v1 value to return.
Removed lucas_tbl.cal calc resource file. This file was made
obsolete by the above rewrite of the lucas.cal resource file.
This file will be removed from the local cal directory and
from CALC_SHAREDIR during a 'make install', 'make clobber',
and 'make uninstall'.
Renamed gen_u0() to gen_u2() in lucas.cal. Provided a gen_u0()
stub function that calls gen_u2() for backward compatibility.
The old gen_v1() method used by the Amdahl 6 group has been
renamed legacy_gen_v1() in lucas.cal. This function is no
longer used by the lucas(h, n) function to test the primality of
h*2^n-1. It is preserved in lucas.cal for historical purposes.
The 'make clobber' rule will attempt to remove all files that
start with libcalc and start with libcustcalc.
The 'man' command is now an alias for the 'help' command.
Fixed extra /'s that were put into CALCPATH because of ${T}.
Fixed extra /'s that were compiled into HELPDIR and CUSTOMHELPDIR.
The fix in 2.12.5.4 to to prepend ${T} in front of the CALCPATH
path components ${CALC_SHAREDIR} and ${CUSTOMDIR} broke the
calc rpm build process. The check-buildroot tool discovered
that the BUILDROOT directory had been improperly put into various
paths and binaries. This has been fixed in 2.12.5.5.
Fixed a crash that showed up on macOS (Darwin) that was reported
by Richard Outerbridge <outer at interlog dot com> and
fixed by Stuart Henderson <stu at spacehopper dot org>.
Thanks goes to both!
The following are the changes from calc version 2.12.5.3 to 2.12.5.3:
Calc version 2.12.5.2 for macOS (Darwin) users, code to installed
calc under /opt/calc. Moreover the CHANGES file did not mention
/opt/calc. Sorry about that!.
A much better tree for macOS (Darwin) users would have been
to install cal under /opt/calc. This release ONLY changes the
macOS (Darwin) install tree to /usr/local.
macOS (Darwin) users who installed calc version 2.12.5.2
should, after installing version 2.12.5.3:
rm -rf /opt/calc
The following are the changes from calc version 2.12.5.1 to 2.12.5.2:
NOTE: calc version 2.12.5.2, for macOS (Darwin) users,
installed under /opt/calc. We neglected to mention this
AND /usr/local would have been a better choice. Sorry!
Fixed in calc version 2.12.5.3.
Removed rules and makefile variables associated with shortened
calc version numbers of less than 4 levels.
Under OS X (Darwin), if /usr/include is missing, warnings
are issued to help the user use xcode-select --install
so that one may properly compile C code.
Lowered REDC levels:
#define MAXREDC 256 /* number of entries in REDC cache */
#define SQ_ALG2 28 /* size for alternative squaring */
config("sq2") == 28 /* was 3388 */
#define MUL_ALG2 28 /* size for alternative multiply */
config("mul2") == 28 /* was 1780 */
#define POW_ALG2 20 /* size for using REDC for powers */
config("pow2") == 20 /* was 176 */
#define REDC_ALG2 25 /* size for using alternative REDC */
config("redc2") == 25 /* was 220 */
The alg_config.cal script appears to be not correctly finding the
best REDC values. While it has been improved, alg_config.cal still
seems to be suspect on how it attempts to find the best values.
Fixed an intro help file mistake found by Roger Hardiman
<roger at rjh dot org dot uk>.
The following are the changes from calc version 2.12.5.0 to 2.12.5.1:
Calc has a new calc-tester mailing list. This list is for those
who are using/testing calc. We also use this list to announce
new versions of calc. To subscribe to the calc-tester mailing
list, visit the following URL:

The following makefile rules that were related to printing the
upper values of the calc version, rules that were made obsolete
in calc version 2.12.4.14, have been removed:
calc_vers calc_ver calc_ve
vers ver ve
Noted that the hash() builtin function, internally known as
quickhash (used for internal objects such as the associative
arrays as well as other internal processes) uses the deprecated
32-bit FNV-0 hash. The use of this deprecated hash is sufficient
for calc internal purposes. Use of FNV-1a is recommended for
a general non-cryptographic quick hash.
The following are the changes from calc version 2.12.4.14 to 2.12.5.0:
For Apple OS X / Darwin target:
MACOSX_DEPLOYMENT_TARGET is no longer defined
using clang compiler
By default, -install-name is used when forming shared libs.
To force -install-name to not be used, set SET_INSTALL_NAME=no.
The have_stdvs.c test uses <stdlib.h> and fixed va_start() test call
that didn't use last arg.
Fixed math_fmt (printf) in value.c where a LEN (SB32) be printed as %d.
Fixed a significant bug where that resulted in an incorrect
complex number comparison. Thanks goes to David Binderman
<dcb314 at hotmail dot com> for identifying the subtle typo!
Make minor fixes to the make depend rule.
Fixed places were calc defined a reserved identifier that
begin with either __ or _[A-Z]. For example, __FILE_H__ has
been replaced with INCLUDE_FILE_H.
Fixed the addall3 example in the script help file. Thanks for this
fix goes to Igor Furlan <igor dot furlan at gmail dot com>.
We made important fixes to the calc command line history:
Fixed a bug in the command line history where calc would sometimes
crash. There was code that used memcpy() instead of memmove()
that could corrupt the command line history when entering a
into into history that was similar to a previous entry. Thanks
goes to Einar Lielmanis <einars at spicausis dot lv> for first
identifying this mistake.
The calc command line history code, in general was not robust.
We made use a patch from Mathias Buhr <napcode at users dot sf
dot net>, that while it uses a bit more memory: is much more
flexible, readable and robust. This patch replaced the improper
use of memcpy() (see above) with better code. Thanks!
The alg_config.cal calc resource file has been reworked to produce
better diagnostics while attempting to determine the ideal values
for mul2, sq2, and pow2. However, it has been shown that this
code is not correct. Suggestions for a replacement are welcome!
calc -u 'read alg_config; config("user_debug", 2),; best_mul2();'
calc -u 'read alg_config; config("user_debug", 2),; best_sq2();'
calc -u 'read alg_config; config("user_debug", 2),; best_pow2();'
Fixed a number of pedantic compiler warnings.
Removed -W and -Wno-comment from the the CCWARN makefile variable.
Removed no_implicit.arg makefile rule. Removed HAVE_NO_IMPLICIT
makefile variable. Removed no_implicit.c source file.
Added WNO_IMPLICT makefile variable to hold the compiler flag
-Wno-implicit for use on selective compile lines.
Added WNO_ERROR_LONG_LONG makefile variable to hold the compiler flag
-Wno-error=long-long for use on selective compile lines.
Added WNO_LONG_LONG makefile variable to hold the compiler flag
-Wno-long-long for use on selective compile lines.
The makefile variable ${MKDIR_ARG} has been replaced with just -p.
Minor fixes were made to the calc.spec.in file.
The target rpm architecture changed from i686 to x86_64. For those
who do not run machine with x86_64, we continue to release a src
rpm. For those without the ability to process an rpm, we will always
to release src tarball.
When building the libcalc and libcustcalc shared libraries,
ONLY the .so and .so.${VERSION} files are created. The .so is
a symlink to the .so.${VERSION} file. Here ${VERSION} is the
full "w.x.y.z" calc version.
are replaced with .include "../../devel/readline/buildlink3.mk", and
USE_GNU_READLINE are removed,
* .include "../../devel/readline/buildlink3.mk" without USE_GNU_READLINE
are replaced with .include "../../mk/readline.buildlink3.mk".
User visible changes:
Fixed a documentation bug for the sgn() builtin.
Added the 1<<8/2 evaluation example to "help unexpected". That
expression evalutes to 128, not 16 as some C programmers might expect.
Fixed a bug in solve.cal where high was not returned in some situations.
Fixed a bug reported by Paul & Karen Tomlinson (paulnkaz at pktomlinson
dot fsnet dot co dot uk) where calling log multiple times with different
values of epsilon resulted in an incorrect value.
Fixed a bug where an certains typos (e.g., calling an unknown
function) would previously cause calc to exit.
changes:
-build system improvements
-Fixed bug where a FILEPOS was copied FPOS_POS_BITS octets instead of
FPOS_POS_LEN octets.
-documentation improvements
This is a major release. Significant changes include:
* calc may be built with static or dynamic shared libraries
* overhauled Makefiles to use system targets
- replaced compiler sets with host targets
- targets include: linux, OS X, FreeBSD, simple, default
- many changes to Makefile variables
* calc source static and extern variables declared with CPP symbols
- to make it easier to compile under certain Windoz environments
- to assist those who are developing a multi-threaded calc lib
* calc library makes it easier to control parse and scan messages
* added Makefile.simple for hosts without GNU Make
* added custom registers
- when calc is run with the -C flag
* dropped support of md5 and sha-0 hashes
* calc supports real and complex exponentiation bases and exponents
- i.e., 2.5 ^ 3.5, 0.5i ^ 0.25, 2.5 ^ 2.718i, 3.13145i ^ 0.30103i
added TEST_TARGET
changes:
Documentation of # operator, comments, and cscripts.
Documented multi-line statement issues.
Added builtins related to user, system and clock time.
Changed runtime() builtin output.
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
Fixed a bug reported by the sourceforge user: cedars where:
ln(exp(6)) == 3 /* WRONG!!! */
incorrectly returned 1. This bug was fixed by Ernest Bowen
The regression test was expanded to cover this issue.
Added minor improvements to hash regression testing of pi().
Fixed "help script" and the calc man page regarding the requirement
of -f to be the last -flag in shell script mode. Further clarified
the meaning and placement of the -f flag.
Moved issues with chi.cal intfile.cal into a "mis-features" section
of the BUGS file. See "help bugs" or the BUGS source file for details.
Added the bug about:
calc 'read ellip; efactor(13*17*19)'
to the BUGS file. See "help bugs" or the BUGS source file for details.
Anyone want to track down and fix this bug?
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
This release adds changes to better support compiling under cygwin,
improved custom function support, including the addition of the
pmodm127 example and config("compile_custom") and config("allow_custom")
calls, and a missing display help file. It fixes configuration
state hashing, document typos, calc -d (to disable printing of the
leading ~), and some compilation warnings reported under OS X.
This release fixes a bug related to post incrementing, some regression failures related to compiling under cygwin, and a number of gcc compiler warnings.
Fixed calc man page examples to move -f to the end of the line.
Thanks goes to Michael Somos <somos at grail dot cba dot csuohio
dot edu> for pointing this out.
Linux and gcc now compiled with -Wall -W -Wno-comment.
Fixed a post increment that was reported by R. Trinler <trinler at
web dot de> and fixed by Ernest Bowen <ernie at turing dot une dot
edu dot au>.
Fixed pi.cal to not depend on the buggy pre-2.11.9 post increment
behavior.
Added config("cygwin") to determine if calc was compiled under Cygwin.
The config("cygwin") is a read-only configuration value that is 1
when calc was compiled under Cygwin and 0 otherwise. Regression
tests 949 and 950 are skipped when config("cygwin") is true.
The Makefile variable HAVE_NO_IMPLICIT is empty by default so that
the Makefile will test if the compiler has a -Wno-implicit flag.
Added HAVE_UNUSED Makefile variable. If HAVE_UNUSED is empty,
then the Makefile will run the have_unused program to determine
if the unused attribute is supported. If HAVE_UNUSED is set to
-DHAVE_NO_UNUSED, then the unused attribute will not be used.
The Makefile builds have_unused.h which defines, if the unused
attribute is supported:
#define HAVE_UNUSED /* yes */
#define UNUSED __attribute__((unused)) /* yes */
or defines, if the unused is not supported (or if the Makefile
variable is HAVE_UNUSED= -DHAVE_NO_UNUSED):
#undef HAVE_UNUSED /* no */
#define UNUSED /* no */
Fixed numerous warnings about comparison between signed and unsigned
value warnings and unused parameter warnings in version.c, zrand.c,
string.c, shs1.c, shs.c, qtrans.c, qmath.c, qfunc.c, md5.c, matfunc.c,
hist.c, file.c, const.c, blkcpy.c, seed.c, opcodes.c, func.c, qio.c,
zrandom.c, custom/c_argv.c, custom/c_devnull.c, custom/c_help.c,
custom/c_sysinfo.c, addop.c and calc.c.
Fixed some typos in this file.
By default, compile with -O3 -g3. The Makefile comments on how some
distributions might need to use -O2 -g or -O -g.
curses.buildlink2.mk. This was wrong because we _really_ do want to
express that we want _n_curses when we include the buildlink2.mk file.
We should have a better way to say that the NetBSD curses doesn't
quite work well enough. In fact, it's far better to depend on ncurses
by default, and exceptionally note when it's okay to use NetBSD curses
for specific packages. We will look into this again in the future.
Clarify that the internal hash as well as the hash builtin
function used by calc, while based on the Fowler/Noll/Vo
hash is NOT an FNV hash.
Made slight performance improvements to calc by an optimization of how
calc's internal hash is computed. The "make chk" regression test
runs about 1.5% faster (when compiled with -O3 on an AMD Athlon)
NO_HASH_CPU_OPTIMIZATION is not defined. Calc's internal hash values
have not changed. By default, NO_HASH_CPU_OPTIMIZATION is NOT defined
and the slightly faster expression is used.
A slight modification of what was known as the "calc new stardard"
configuration (calc -n or config("all", "newstd")) is now the default
calc configuration. The flag:
calc -O
was added to get the old classic calc configuration. The flag command
line flag, -n, now does nothing. Use of -n is deprecated and may go
away / be used for something else in the future.
The following table gives the summary of these changes:
pre v2.11.8 v2.11.8
default pre v2.11.8 -O & oldstd v2.11.8
and oldstd -n & newstd classic cfg default
--------------------------------------------------------
epsilon 1e-20 1e-10 1e-20 1e-20
quo 2 2 2 2
outround 2 24 2 24
leadzero 0 1 0 1
fullzero 0 1 0 0
prompt > ; > ;
more >> ;; >> ;;
With the exception of epsilon being 1e-20, and fullzero being unset,
the new default calc config is like it was (pre-2.11.8) with calc -n /
config("all", "newstd").
The new default config is the old classic config with outround being
24, leadzero being set, and the prompts being ;'s.
