Documented unexpected behavior when calc is running in
"shell script mode" and the prompt builtin function is used
without the -p flag. Updated help/prompt, help/unexpected
and the calc man page accordingly.
Unless calc is given the -p command line option, calc will reopen
stdin as /dev/null instead of just closing stdin. This prevents
subsequent opens grabbing the 1st file descriptor.
Disable regress tests 4709, 4710, and 7763 because they print
multi-byte sequences, which are just fine for calc, the awk
used to evaluate the regression suite output in some legacy
systems report a "multibyte conversion failure".
Added a number of missing Makefile variables to the "make env" rule.
The man command is used to format the calc.1 man page into calc.usage.
The "help calc" command now prints the formatted calc man page (calc.usage).
The "help man" command now prints the formatted calc man page (calc.usage).
The "help usage" command now prints the formatted calc man page (calc.usage).
The file, calc.cat1, is formed by gzipping the calc.usage
formatted man page. The calc.cat1 is installed as the calc
cat section 1 man page.
Updated the Copyright string in version.c to refer to
the COPYING file and the "help copying" command.
Added calc.cat1 to .gitignore. Using "sort -d -u" to sort .gitignore content.
Avoiding use of modern [[ and ]] in Makefile for those legacy systems
whose shell do not support them. *sigh*
Fixed the order of "help full" to match the order of topics listed
buy the "help help" command.
Sorted the halias[] help topics table in help.c using sort -d -u.
The tarball for calc version 2.15.0.0 was missing version.h.
The version.h is now listed as part of the calc distribution.
Added a chk_tree tool to help look for problems such as files that are
result of building calc that are also part of the calc distribution,
and files that are part of the calc source that are missing from the
calc distribution, and files that are of unknown status that are either
result of building calc nor missing from the calc distribution.
Updated file lists in Makefile, sorting as needed.
Updated Makefile PHONY rule to include Makefile rules that are NOT files.
Reduced make chatter for rules that build lists.
Added make verifydist to verify the existence of files that are part of
the calc distribution.
Added make verifydist to make prep.
Added a chk_tree double check, one after make clobber, one before the
final make chk, to make prep.
Improve builtin function strings, as printed by help builtin,
that use an optional accuracy (epsilon) arg by adding a comma.
Added the following new trigonometric functions:
crd(x [,eps]) trigonometric chord of a unit circle
acrd(x [,eps]) inverse trigonometric chord of a unit circle
Added the following new trigonometric functions:
exsec(x [,eps]) exterior trigonometric secant
aexsec(x [,eps]) inverse exterior trigonometric secant
excsc(x [,eps]) exterior trigonometric cosecant
aexcsc(x [,eps]) inverse exterior trigonometric cosecant
Added to test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.
Added to test 34dd, some if the missing inverse trigonometric tests.
Fixed SEE ALSO typo in help randperm.
Added the following new trigonometric functions:
haversin(x [,eps]) half versed trigonometric sine
hacoversin(x [,eps]) half coversed trigonometric sine
havercos(x [,eps]) half versed trigonometric cosine
hacovercos(x [,eps]) half coversed trigonometric cosine
ahaversin(x [,eps]) inverse half versed trigonometric sine
ahacoversin(x [,eps]) inverse half coversed trigonometric sine
ahavercos(x [,eps]) inverse half versed trigonometric cosine
ahacovercos(x [,eps]) inverse half coversed trigonometric cosine
Fixed calc regression test 42dd to set the display value back to 20.
Added test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.
Fix and improve recently comments and variable names added new
trigonometric functions in comfunc.c, func.c, qtrans.c.
Rename E_BROUND to E_BROUND_1 as per an earlier change
on the E_STRING formats.
E_BROUND ==> E_BROUND_1
Improve the ciarify of calc regression suite (regress.cal) to mostly
use E_STRING errsym instead of numeric errnum values for error()
and errno() related tests.
Added tests to the calc regression test suite (cal/regress.cal) to
verify that the errnum calc computation error codes and their
E_STRING values have not changed.
NOTE: errstr was renamed to errsym.
Added errsym builtin function. The errsym(errnum | "E_STRING")
builtin, , when given a valid integer errnum that corresponds to a
calc error condition, will return an E_STRING string, AND when given
a valid E_STRING string that is associated with a calc error
condition, will return errnum integer that corresponds to a calc
error condition.
Supplying a non-integer numeric errnum code to error(), errno(),
strerror(), or errsym() will result in an error.
Added complex multiple approximation function to commath.c so
that users of libcalc may directly round complex number to
nearest multiple of a given real number:
E_FUNC COMPLEX *cmappr(COMPLEX *c, NUMBER *e, long rnd, bool cfree);
For example:
COMPLEX *c; /* complex number to round to nearest epsilon */
NUMBER *eps; /* epsilon rounding precision */
COMPLEX *res; /* c rounded to nearest epsilon */
long rnd = 24L; /* a common rounding mode */
bool ok_to_free; /* true ==> free c, false ==> do not free c */
...
res = cmappr(c, eps, ok_to_free);
The complex trigonometric functions tan, cot, sec, csc were implemented
in func.c as calls to complex sin and complex cos. We added the
direct calls to comfunc.c so that users of libcalc may
call them directly:
E_FUNC COMPLEX *c_tan(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_cot(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_sec(COMPLEX *c, NUMBER *eps);
E_FUNC COMPLEX *c_cot(COMPLEX *c, NUMBER *eps);
Improved help files for sin, cos, tan, cot, sec, csc. In case
of tan, cot, sec, csc corrected help file was corrected to
indicate that complex arguments are allowed. This was a help
file oversight from long ago when those trigonometric functions
Expanded the calc regression test suite test 34dd to test various
real and complex values for sin, cos, tan, cot, sec, csc.
Fixed more documentation and code comments that referred to the old
additive 55 (a55) shuffle pseudo-random number generator. We have
been using the subtractive 100 shuffle pseudo-random number generator
in place of the additive 55 generator for a while now.
Updated the cal/README to reflect the new names
of the calc regression test suite files.
Updated cal/Makefile to remove, when installing,
old names for calc regression test suite files.
Added missing getpgid_tmp to .gitignore.
To make the meaning a bit more clear in cal/regress.cal, we have
renamed the following test calc resource files that are related to
the calc regression test suite:
cal/test1700.cal -> cal/test8000.read.cal
cal/test2300.cal -> cal/test2300.obj_incdec.cal
cal/test2600.cal -> cal/test2600.numfunc.cal
cal/test2700.cal -> cal/test2700.isqrt.cal
cal/test3100.cal -> cal/test3100.matobj.cal
cal/test3400.cal -> cal/test3400.trig.cal
cal/test4000.cal -> cal/test4000.ptest.cal
cal/test4100.cal -> cal/test4100.redc.cal
cal/test4600.cal -> cal/test4600.fileop.cal
cal/test5100.cal -> cal/test5100.newdecl.cal
cal/test5200.cal -> cal/test5200.globstat.cal
cal/test8400.cal -> cal/test8400.quit.cal
cal/test8500.cal -> cal/test8500.divmod.cal
cal/test8600.cal -> cal/test8600.maxargs.cal
cal/set8700.cal -> cal/test8700.dotest.cal
cal/test8900.cal -> cal/test8900.special.cal
cal/test9300.cal -> cal/test9300.frem.cal
Added to test 94dd, read of a number of new calc resource files
that are not already read as a result of the calc regression test suite.
Improve comments about use of the ${CALC_ENV} Makefile variable.
Noted in Makefile.cal where and how the ${CALC_ENV} is used.
Use ${CALC_ENV} Makefile variable were needed.
Modified regression test cal/regress.cal: in some cases test numbers
were adjusted. Add comments indicate which test numbers apply to
which code. Indicated where there is room for new tests.
Expanded the end of test numbers from 9999 to 99999.
Fixed how the historical trigonometric functions call
the underlying trigonometric functions. This fixes a
number of issues where the function for values of 0.
Updated cal/regress.cal to test historical trigonometric functions
at the 0 value.
Improved trig help files.
Added new vercos(x, [,eps]) for versed cosine and covercos(x, [,eps])
for inverse versed cosine.
Added new avercos(x, [,eps]) for inverse versed cosine and acovercos(x, [,eps])
for inverse coversed cosine.
In cases where the real value to the inverse versed sine and the
inverse coversed sine function produces a complex value, the
conversion from real to complex was incorrect.
Added c_to_q(COMPLEX *c, bool cfree) to make is easier to convert
a COMPLEX value that is real (imag part is 0) into a NUMBER and
optionally free the COMPLEX value.
The func.c code now uses c_to_q().
NOTE: There is a XXX bug marked in the f_aversin() and f_acoversin()
that still needs to be fixed.
Added new aversin(x, [,eps]) for inverse versed sine and acoversin(x, [,eps])
for inverse coversed sine.
Improved trig function help files to reference use of complex arguments
that while supported were not documented.
Removed old Makefile testing rules for make dbx and make gdb.
Improved "make run" to execute calccalc using shared libraries
from the local directory, and with reading of the startup scripts
disabled.
Changed "make prep" to perform various tests that are used to
help verify that calc is ready for a release.
Added Makefile testing rule testfuncsort to check for the sort
of the builtin function list. Changed the order that builtin
functions are listed by "show builtin" and the help/builtin to
match the sorting of "LANG=C LC_ALL=C sort -d -u".
Moved versin() and coversin() to bottom of functions in func.c
(however the builtin function list remains sorted).
Created a historical trig functions section for cmath.h and qmath.h.
Moved cal/test3500.cal to cal/test9300.cal to make room
for future trip tests going from test 3427 thru 3599.
Add new logn(x, n [,eps]) builtin to compute logarithms to base n.
Verify that eps arguments (error tolerance arguments that override
the default epsilon value) to builtin functions have proper values.
Previously the eps argument had little to no value checks for
many builtin functions.
Document in help files for builtin functions that take eps arguments,
the LIMIT range for such eps values.
Added log2(x [,eps]) builtin function. When x is an integer
power of 2, log2(x) will return an integer, otherwise it will
return the equivalent of ln(x)/ln(2).
Fix "Under source code control" date for new version.h file.
Sorted the order of symbols printed by "make env".
Test if <stdbool.h> exists and set HAVE_STDBOOL_H accordingly
in have_stdbool.h. Added HAVE_STDBOOL_H to allow one to force
this value.
Added "bool.h" include file to support use of boolean symbols,
true and false for pre-c99 C compilers. The "bool.h" include
file defines TRUE as true, FALSE as false, and BOOL as bool:
for backward compatibility.
The sign in a ZVALUE is now of type SIGN, whcih is either
SB32 when CALC2_COMPAT is defined, or a bool.
Replaced in C source, TRUE with true, FALSE with false, and
BOOL with bool.
Sort .gitignore. Add calc.spec to .gitignore.
Update format of header part of Makefiles.
Modify calc.spec.in to handle dynamic shared libraries with 3-digit
version numbers.
Removed the ${CAL_PASSDOWN}, ${HELP_PASSDOWN}, ${HELP_PASSDOWN},
${CSCRIPT_PASSDOWN} Makefile variables as the new Makefile
include files keep Makefile variables in sync.
Fixed the ability of calc to compile when CUSTOM is undefined
(i.e., -UCUSTOM). The libcustcalc is always built, regardless
of the $(ALLOW_CUSTOM} Makefile variable. However when CUSTOM
is undefined, the bulk of custom functions are not defined.
Moved makefile variables that configure calc and configure how to
compile calc from Makefile into a new Makefile.config file.
The Makeifle includes the Makefile.config file.
The cal/Makeifle includes the Makefile.config file.
The cscript/Makeifle includes the Makefile.config file.
The custom/Makeifle includes the Makefile.config file.
The help/Makeifle includes the Makefile.config file.
Now, the Makefile.config file will consistently configure
calc and how calc is compiled and built by all calc Makefiles.
The platform target section from the old Makefile has been moved to
a new file, Makefile.target. The custom/Makefile no longer includes
Makefile.
The Makeifle includes the Makefile.target file.
The cal/Makeifle includes the Makefile.target file.
The cscript/Makeifle includes the Makefile.target file.
The custom/Makeifle includes the Makefile.target file.
The help/Makeifle includes the Makefile.target file.
Now, the Makefile.target file will consistently set
target information for all calc Makefiles.
The cal/Makeifle includes the Makefile.local file.
The cscript/Makeifle includes the Makefile.local file.
The custom/Makeifle includes the Makefile.local file.
The help/Makeifle includes the Makefile.local file.
Thus, one may modify or append many Makefile variables
in all calc Makefiles.
Updated COPYING file to indicate that these files are now
covered under "The Unlicense" (see https://unlicense.org):
sha1.c
sha1.h
cal/dotest.cal
cal/screen.cal
Updated help/credit to match the above changes to COPYING.
Updated CONTRIB-CODE and calc.man to refer to using GitHub pull requests
for contributing to calc (instead of using Email).
Updated BUGS and calc.man to refer to using GitHub issues
for reporting calc bugs (instead of using Email).
Updated QUESTIONS and calc.man to refer to using GitHub issues
for asking calc questions (instead of using Email).
Fixed Makefile.local command example to refer to overriding the
Makefile variable DEBUG (instead of CDEBUG).
Fixed all make chk ASAN warnings under macOS 13.2.1 when calc is compiled
with the following uncommented lines in Makefile.local:
DEBUG:= -O0 -g
CFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
LDFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
CALC_ENV+= ASAN_OPTIONS=detect_stack_use_after_return=1
Improved how pointers to functions are declared for the builtins
array in func.c to avoid function declarations without a prototype
that is now deprecated in C.
Improved how pointers to functions are declared for the opcodes
array in opcodes.c to avoid function declarations without a prototype
Replaced use of egrep with grep -E in Makefiles.
Fixed cases where variables were set but not used in symbol.c, calc.c,
and the main function in func.c as used by funclist.c.
Added rule name to "DO NOT EDIT -- generated by the Makefile" lines
in constructed files.
Test if <sys/vfs.h> exists and set HAVE_SYS_VFS_H accordingly
in have_sys_vfs.h. Added HAVE_SYS_VFS_H to allow one to force
this value.
Test if <sys/param.h> exists and set HAVE_SYS_PARAM_H accordingly
in have_sys_param.h. Added HAVE_SYS_PARAM_H to allow one to force
this value.
Test if <sys/mount.h> exists and set HAVE_SYS_MOUNT_H accordingly
in have_sys_mount.h. Added HAVE_SYS_MOUNT_H to allow one to force
this value.
Test if the system as the statfs() system call and set HAVE_STATFS
accordingly in have_statfs.h. Added HAVE_STATFS to allow one
to force this value.
The pseudo_seed() function will also try to call statfs() if
possible and permitted by the HAVE_STATFS value.
Added config("fraction_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space").
Added config("complex_space", boolean). The "complex_space" controls
whether or not a space (' ') is printed before and after the + or -
in complex values.
By default, config("complex_space") is false.
For example, with the default, config("complex_space", 0):
; asin(2)
1.57079632679489661923-1.31695789692481670863i
With config("complex_space", 1):
; asin(2)
1.57079632679489661923 - 1.31695789692481670863i
NOTE: Use of config("complex_space", 1) can break printing and scanning
of fractional values via "%r".
NOTE: Use of config("complex_space", 1) can break printing and scanning
of complex values via "%c".
Added config("complex_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("complex_space").
Added config("tilde_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space").
Added config("fraction_space", boolean). The "fraction_space" controls
whether or not a space (' ') is printed before and after fractions.
By default, config("fraction_space") is false.
For example, with the default, config("fraction_space", 0):
; base(1/3),
; 1/7
1/7
With config("fraction_space", 1):
; base(1/3),
; 1/7
1 / 7
NOTE: Use of config("fraction_space", 1) can break printing and scanning
of fractional values via "%r".
NOTE: Use of config("fraction_space", 1) can break printing and scanning
of complex values via "%c".
Added config("fraction_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space").
Added config("tilde_space", boolean). The "tilde_space" controls
whether or not a space (' ') is printed after leading tilde ('~').
By default, config("tilde_space") is true, which is a change
from past behavior. For example, now:
; 1/3
~ 0.33333333333333333333
With config("tilde_space", 0):
; 1/3
~0.33333333333333333333
To disable "tilde_space", use config("tilde_space", 0) on the
command line and/or use config("tilde_space", 0),; in your ~/.calcrc.
Thanks goes to <GitHub use ljramalho> for this suggestion.
Added config("tilde_space", boolean) to help/config, along with
a few few minor text improvements. Updated cal/regress to test
config("tilde_space") and to account for the new default.
