calc 2.14.0.2 release

The following are the changes in this release:

The clean and clobber makefile rules no longer list custom/Makefile
as a dependency.

Unfortunately due to the complex dependency issues between
Makefile, Makefile.ship and custom/Makefile, parallel GNU make
is NOT recommended.  Sorry (tm Canada) :)

Fixed a few typos in CHANGES.

As a side note: We stayed v2.13.x was kept for only a short time.
The move to 2.14.x was motivated by non-compatible changes due to
the default order of CALCRC, plus some new builtin functions.

More changes are likely, so we might see another v2.14.0.x release
before things are declared "recommended stable".

Not that we wan to discourage people from trying v2.14.0, you should
try it.  We just want things to become stable and well field tested
before we reach the "recommended stable" release state.

calc 2.14.0.0 release

The following are the changes in this release:

The :-separated default CALCRC value has been reversed.
The default CALCRC was:

${CALC_SHAREDIR}/startup:~/.calcrc:./.calcinit

The default CALCRC is now:

./.calcinit:~/.calcrc:${CALC_SHAREDIR}/startup

See "help environment" for details.

Added engineering mode as per a GitHub pull request from
<GitHub user heitzmann>.  Thank you!  For example:

; config("mode","eng"),
; 10^41
	100e39

or for example:

; base(1000),
; 2^23209-1
	~402.87411577898877818187e6984

For more information see:

help base

Added regression test code for engineering mode.  Improved and
expanded regression test code related to the base() and base2()
builtin functions.

Fixed a critical bug in the above mentioned pull request where
a call to base2(1000) would make calc unstable and likely to
dump core.

calc 2.13.0.1 release

The following are the changes in this release:

Replaced /usr/local with the use of ${PREFIX} in calc Makefiles.

The ${PREFIX} is not the same as ${T}.  The ${T} specifies
a top level directory under which calc installs things.
While usually ${T} is empty, it can be specific path
as if calc where "chrooted" during an install.
The ${PREFIX} value, during install, is a path between
the top level ${T} install directory and the object
such as an include file.

Corrected a few more typos in Makefile comments.

Added Makefile.local, a file with a single comment.  The main
Makefile includes Makefile.local just before the first all rule.
One may override any Makefile setting by modifying Makefile.local.
For example, Makefile.local could force BLD_TYPE:

HAVE_STRING_H:= YES
HAVE_TIMES_H:= YES
SED:= /usr/local/bin/nsed

Added ${LOC_MKF} to specify the make of the file that is
included just before the all file.  So one could place
the above override lines into a different file and call
make changing the ${LOC_MKF} value.  For example:

make LOC_MKF=Makefile.private clobber all chk

Updated HOWTO.INSTALL to mention Makefile.local.

calc 2.13.0.0 release

The following are the changes in this release:

Fixed typo (missing quotes) in the env rule.

Fixed intendation problem in CHANGES.

Combined 2.12.9.1 changes into the 2.12.8.2 to 2.12.9.0
range, and thus renamed the range to 2.12.8.2 to 2.12.9.1.

Fixed issues related to building Makefile.simple.

Fixed how the Makefile variable MANPATH is set for macOS.

Added a bunch of information to the near bottom of HOWTO.INSTALL
on calc Makefiles.  This information discusses the various
Makefiles found in the calc source.

Added comments in various calc Makefiles about their origin.
In particular, for Makefiles that are constructed such as
Makefile.simple, custom/Makefile and custom/Makefile.simple
there are comments about how they were made.

For all calc Makefiles, including those in sub-directories,
near the top there is now a line of the form:

# SRC: ... some message about the origin ...

Fixed how the calc(1) man page is installed under macOS.

Fixed how calc man page in ${CATDIR} is formed.

Fixed how Makefile.simple is formed.

Fixed the #! calc script argument processing.  The initial #!
line must end in a -f.  For example, if calc is in /usr/local/bin/calc,
then the following would be the first line of a calc script:

#!/usr/local/bin/calc -f
...

It is common that -q be usde with a calc script, so assuming the
same /usr/local/bin/calc path:

#!/usr/local/bin/calc -q -f
...

Use of -s in the #! first line of a calc script is not needed
since -f implies -f.

The argv() will now return values more typical of C's main().
Before it returned one less than the number of arguments.  Now,
for example, when calc is given 2 args, argv() will return 3.

The value of argv(0) will be the path to calc, or in the
case of a #! calc cscript, it will return the name of the script.

Updated the calc man page and help/argv to reflect the
above changes.

Improved the formatting of the calc man page.

Fixed the formation of the win32 sub-directory via the win32_hsrc
Makefile rule.

Due to incompatible changes to the argv() function, and #! calc
scripts, we are setting the version to the next minor number:

2.13.0

calc 2.12.9.1 release

The following are the changes in this release:

Fixed a typo typo in help/Makefile that caused the build of
2.12.9.0 to fail in a number of cases.  Thanks to a report by
<GitHub user balducci>.

Pass form Makefile variables ${Q}, ${S}, ${E}, ${H} and ${V} down
to all sub-directory Makefiles from the top level Makefile.

calc 2.12.9.0 release

The following are the changes in this release:

Added notes to help/unexpected about:

display() will limit the number of digits printed after decimal point

%d will format after the decimal point for non-integer numeric values

%x will format as fractions for non-integer numeric values

fprintf(fd, "%d\n", huge_value) may need fflush(fd) to finish

Fixed Makefile dependencies for the args.h rule.

Fixed Makefile cases where echo with -n is used.  On some systems,
/bin/sh does not use -n, so we must call /bin/echo -n instead
via the ${ECHON} Makefile variable.

Add missing standard tools to sub-Makefiles to make them
easier to invoke directly.

Sort lists of standard tool Makefile variables and remove duplicates.

Declare the SHELL at the top of Makefiles.

Fixed the depend rule in the custom Makefile.

Improved the messages produced by the depend in the Makefiles.

Changed the UNUSED define in have_unused.h to be a macro with
a parameter.  Changed all use of UNUSED in *.c to be UNUSED(x).

Removed need for HAVE_UNUSED in building the have_unused.h file.

 CCBAN is given to ${CC} in order to control if banned.h is in effect.

 The banned.h attempts to ban the use of certain dangerous functions
 that, if improperly used, could compromise the computational integrity
 if calculations.

 In the case of calc, we are motivated in part by the desire for calc
 to correctly calculate: even during extremely long calculations.

 If UNBAN is NOT defined, then calling certain functions
 will result in a call to a non-existent function (link error).

 While we do NOT encourage defining UNBAN, there may be
 a system / compiler environment where re-defining a
 function may lead to a fatal compiler complication.
 If that happens, consider compiling as:

make clobber all chk CCBAN=-DUNBAN

 as see if this is a work-a-round.

 If YOU discover a need for the -DUNBAN work-a-round, PLEASE tell us!
 Please send us a bug report.  See the file:

BUGS

 or the URL:

http://www.isthe.com/chongo/tech/comp/calc/calc-bugrept.html

 for how to send us such a bug report.

 Added the building of have_ban_pragma.h, which will determine
 if "#pragma GCC poison func_name" is supported.  If it is not,
 or of HAVE_PRAGMA_GCC_POSION=-DHAVE_NO_PRAGMA_GCC_POSION, then
 banned.h will have no effect.

 Fixed building of the have_getpgid.h file.
 Fixed building of the have_getprid.h file.
 Fixed building of the have_getsid.h file.
 Fixed building of the have_gettime.h file.
 Fixed building of the have_strdup.h file.
 Fixed building of the have_ustat.h file.
 Fixed building of the have_rusage.h file.

 Added HAVE_NO_STRLCPY to control if we want to test if
 the system has a strlcpy() function.  This in turn produces
 the have_strlcpy.h file wherein the symbol HAVE_STRLCPY will
 be defined, or not depending if the system comes with a
 strlcpy() function.

 If the system does not have a strlcpy() function, we
 compile our own strlcpy() function.  See strl.c for details.

 Added HAVE_NO_STRLCAT to control if we want to test if
 the system has a strlcat() function.  This in turn produces
 the have_strlcat.h file wherein the symbol HAVE_STRLCAT will
 be defined, or not depending if the system comes with a
 strlcat() function.

 If the system does not have a strlcat() function, we
 compile our own strlcat() function.  See strl.c for details.

 Fixed places were <string.h>, using #ifdef HAVE_STRING_H
 for legacy systems that do not have that include file.

 Added ${H} Makefile symbol to control the announcement
 of forming and having formed hsrc related files.  By default
 H=@ (announce hsrc file formation) vs. H=@: to silence hsrc
 related file formation.

 Explicitly turn off quiet mode (set Makefile variable ${Q} to
 be empty) when building rpms.

 Improved and fixed the hsrc build process.

 Forming rpms is performed in verbose mode to assist debugging
 to the rpm build process.

 Compile custom code, if needed, after main code is compiled.

calc 2.12.8.2 release

The following are the changes in this release:

Calc can now correctly compile without CUSTOM being defined,
thanks to a report by <GitHub user barsnick>.

calc 2.12.8.1 release

The following are the changes in this release:

Fixed how the *.tar.bz2 are formed.  The calc-2.12.8.0.tar.bz2 file
that was formed for calc version 2.12.8.0 was missing most files.

Expanded 'make chk' to also verify that 'make distchk' and 'make
distlist' execute successfully.  This will help check a regression
of the bug that produced the bogus calc-2.12.8.0.tar.bz2 file.

Added additional regression tests related 0^(zero_expression)==1.

calc 2.12.8.0 release

The following are the changes in this release:

Fixed a mistake in "help intro" where some inserted text changed
the value of "." and thus made the next result incorrect.

Clarified in "help factor" that 1 is returned if no
factor below the limit was found.

Removed Makefile variable ${MAKEFILE_REV}.

The missing cscript/square.calc file has been restored.

Fixed compiler errors and warnings related to GCC.  In particular,
gcc/9.3.1 and gcc/10.2.1 now compile calc without any compiler
errors or warnings, even with -Werror -Wextra -pedantic.

To print out information about the calc compilation
environment, we added the following make rule:

make calcinfo

Improved how 'make debug' operates.

Moved help/contrib to CONTRIB-CODE.  The help/contrib file
is now build from a copy of CONTRIB-CODE.

Created a new calc bug report Email address.  Created a new
calc question Email address.  Created a new calc contribution
Email address.  See the BUGS file for details.

Added "help questions" to print the QUESTIONS help file.

If the environment variable $CALCHELP is defined and is non-empty,
then calc help files will be in the directory by the $CALCHISTFILE
environment variable.

If the environment variable $CALCCUSTOMHELP is defined and is
non-empty, then custom calc help files will be in the directory
by the $CALCCUSTOMHELP environment variable.

Fixed a number of typos in text and in source code comments.
