+The following are the changes from calc version 2.14.2.3 to date:
+
+    Fixed missing <string.h include in have_fpos_pos.c.
+
+    Change calc version from 2.14.1.2 to 2.14.2.3 as part of a test to
+    build calc RPMs on a reference RHEL8.7 platform (formerly a RHEL7.9
+    platform).
+
+
+The following are the changes from calc version 2.14.2.0 to 2.14.1.2:
+
+    Attempted to address a paranoid compiler warning -Wmaybe-uninitialized
+    in swap_HALF_in_ZVALUE() where the gcc compiler seems to ignore the
+    fact that calling not_reached() above the call to zcopyval()
+    should prevent dest from being NULL to the 1st zcopyval() call.
+    Thanks to <GitHub user mattdm> for raising this potential concern.
+
+    Fixed a -Wuse-after-free warning that identified a call to realloc()
+    in find_tty_state() could move the fd_setup array.  Thanks goes to
+    <GitHub user mattdm> for reporting this bug!
+
+    In find_tty_state(), we changed how we expand fd_orig as an original
+    pre-modified copy of fd_setup.  We realloc the fd_orig array and copy
+    the fd_setup into it first, before touching the fd_setup array.
+
+    In pseudo_seed(), we removed a call to setjmp() that was only
+    there to add more information to mix into the seed.  For compilers
+    such as gcc that used -Wclobbered, the call to setjmp() gave the
+    impression that the hash_val might be clobbered by a longjmp().
+    Where there is no longjmp() that would use the previous setjmp(),
+    the gcc compiler has nil ways to notice that. So to avoid confusion
+    we removed the setjmp() call.  Thanks to <GitHub user mattdm> for
+    raising this potential concern.
+
+    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 false.
+
+    For example, with the default, config("tilde_space", 0):
+
+	; 1/3
+		~0.33333333333333333333
+	; sqrt(7 + 5i,1e-100)
+		~2.79305614578749801863+~0.89507688693280053094i
+
+    With config("tilde_space", 1):
+
+	; 1/3
+		~ 0.33333333333333333333
+	; sqrt(7 + 5i,1e-100)
+		~ 2.79305614578749801863+~ 0.89507688693280053094i
+
+    NOTE: Use of config("tilde_space", 1) can break printing and scanning
+	  of complex values via "%c".
+
+    To enable "tilde_space", use config("tilde_space", 1) on the
+    command line and/or use config("tilde_space", 1),; 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").
+
+    For example, with the default, config("tilde_space", 0):
+
+	; pi(1e-50)
+		~3.14159265358979323846
+
+    With config("tilde_space", 1):
+
+	; pi(1e-50)
+		~ 3.14159265358979323846
+
+    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

+
+    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

+
+    Clarify in the calc man page, the relationship between -q and
+    calc start scripts such as the ~/.calcrc file.
+
+    Fixed in the calc man page, the issue of -f not implying -q.
+
+
+The following are the changes from calc version 2.14.1.2 to date:
+
+    Restored use of the #define FPOS_POS_LEN symbol.  This refers to
+    the length of the __pos element (if the __pos element exists),
+    the fpos_t type (if that type exists).
+
+    Changed SWAP_HALF_IN_FILEPOS(dest, src) mato to use FILEPOS_LEN Little
+    Endian when FILEPOS is a simple scalar type (i.e., HAVE_FILEPOS_SCALAR
+    is defined).
+
+    Changed #define HAVE_FPOS to HAVE_FGETSETPOS.
+
+    Corrected comment in have_fpos_pos.h.  The HAVE_FPOS_POS symbol was
+    NOT related to fgetpos & fsetpos but rather if we we have an __pos
+    element in FILEPOS.
+
+    Changed #define HAVE_NO_FPOS to HAVE_NO_FGETSETPOS.
+
+    Improved comments in have_fpos_pos.h to show why and how
+    HAVE_FPOS_POS, FPOS_POS_BITS, and FPOS_POS_LEN were defined or undefed.
+
+    Changed showfiles builtin to print sizes cast to (long int) with
+    the "%ld" printf format to avoid implementations that do not support
+    the "%lld" printf format specifier.
+
+    Renamed have_fpos.h to have_fgetsetpos.h.  Renamed CALC_HAVE_FPOS_H
+    to CALC_HAVE_FGETSETPOS_H.  The make install and the olduninstall
+    rules remove the any old have_fpos.h that was previously installed.
+
+    Added swap_HALFs(dest, src, len) function to byteswap.c.
+
+    Calc can now handle Big Engian file position sizes that are a
+    multiple of BASEB bits in length.  Before handle Big Engian file
+    positions could only be 32 and 64 bits in length.  This will allow,
+    for example, a Big Engian file position size of 128 (assuming that
+    128/BASEB is is an integer).
+
+    Temporary workaround for musl libc systems such as gentoo Linux that
+    allows them to compile calc and successfully run the regression test.
+
+
+The following are the changes from calc version 2.14.1.1 to 2.14.1.1:
+
+    Added a few remarks on calc version numbers to version.c.
+
+    Fixed how fposval.h is built.  On a number of systems, the fposval.c
+    file failed to compile incorrectly.  This caused problems for systems in
+    which fposval.h.def was not correct.
+
+    Fixed how have_memmv.h is built.  On a number of systems, the have_memmv.c
+    file failed to compile incorrectly, producing a potentially incorrect
+    have_memmv.h file for such systems.
+
+    Fixed how align32.h is built.  On a number of systems, the align32.c
+    file failed to compile incorrectly, producing a potentially incorrect
+    align32.h file for such systems.
+
+    Fixed how have_newstr.h is built.  On a number of systems, the have_newstr.c
+    failed to compile incorrectly, producing a potentially incorrect
+    have_newstr.h file for such systems.
+
+    Fixed how have_strdup.h is built.  On a number of systems, the have_strdup.c
+    file failed to compile incorrectly, producing a potentially incorrect
+    have_strdup.h file for such systems.
+
+    Fixed how have_strlcat.h is built.  On a number of systems, the have_strlcat.c
+    file failed to compile incorrectly, producing a potentially incorrect
+    have_strlcat.h file for such systems.
+
+    Fixed how have_strlcpy.h is built.  On a number of systems, the have_strlcpy.c
+    file failed to compile incorrectly, producing a potentially incorrect
+    have_strlcpy.h file for such systems.
+
+    Fixed how have_uid_t.h is built.  On a number of systems, the have_uid_t.c
+    file failed to compile incorrectly, producing a potentially incorrect
+    have_uid_t.h file for such systems.
+

+    file failed to compile incorrectly, producing a potentially incorrect
+    have_uid_t.h file for such systems.
+
+    Added full_debug rule to Makefile.  This does the work of the
+    old debug rule in a more verbose mode by using Q= H=@ S= E= V=@.
+
+    The debug rule in the Makefile now pre-removes debug.out and then
+    runs make full_debug sending stdout and stderr to debug.out.  It then
+    prints a few instructions about filing a GitHub issue bug report.
+
+    The full_debug rule will no longer stop when one of the sub-tasks
+    failed (exit non-zero).

 An effort is being made to allow windows users to compile calc using the
 Cygwin project (http://sources.redhat.com/cygwin/) with the GCC compiler
-and Un*x tools for Windows.
+and Unix tools for Windows.

 The major porting work for Cygwin was performed by Thomas Jones-Low
 (tjoneslo at softstart dot com).

-In March 2009, Michael Penk (mpenk at wuska dot com) reported success in
-installs under Cygwin:
+In December 2022, GitHub user @Leoongithub successfully compiled
+calc-2.14.1.2 under cygwin 2.924 (64 bit). The following are the
+compilation steps that GitHub user @Leoongithub recommends:

-    On my fairly complete Cygwin installs, everything compiles,
-    checks, and installs correctly.  My Cygwin is configured
-    in a very standard way (out of the box, using all of Cygwin's
-    defaults).  The install worked on 5 different machines with
-    Cygwin on them: one XP home, one XP professional, and three
-    Vista professionals.
+0. Install the latest version of cygwin (https://cygwin.com/install.html).

-Using the calc Makefile, he did the following:
+    NOTE: In addition to the default packages, you also need to check these
+	  three packages: gcc-core, make, and libreadline-devel. The version
+	  of these packages does not matter. Just choose the latest version.

-    make all target=Cygwin
-    make check
-    make install
+    NOTE: The addition of "target=Cygwin" to make commands below
+	  is done just in case the target is not set properly by make.

-He also reports:
+1. Change (cd) into the top of the source code directory of calc.

-    Of course, one should be logged in as an Administrator when
-    one builds and installs calc.
+   NOTE: The make command assume you are at the top of the calc source directory.
+
+2. make clobber target=Cygwin
+
+   NOTE: This helps ensure that you are starting from a so-called "clean slate",
+	 and that you have nothing hanging around from previous attempts to compile.
+
+3. make all target=Cygwin
+
+   NOTE: If successful, you should have a calc executable.  However that executable
+	 may not be working properly.  Advance to step (4) to test.
+
+4. make chk target=Cygwin
+
+   NOTE: If you want this command be be verbose, try:
+
+	    make check target=Cygwin
+
+   NOTE: This will run calc with the regress.cal regression suite.  This step could take
+	 for a while to run, depending on the speed/performance of your machine.
+	 If all is well (all regression tests pass), you will see at the end:
+
+	    chk OK
+
+         Otherwise you may see calc exit non-zero after it prints some lines with '****'
+	 error messages followed by a line including a final error count of the form:
+
+	   **** 2 error(s) found  \/++\/
+
+         If you see some errors that may relate to files and I/O, all may not be lost.
+	 It could simply mean that your Windows environment is not conforming to standard
+	 I/O and file operations.  The calc mathematical engine may be just fine.  On the
+	 other hand if you see mathematical related regression test failures, this is
+	 bad sign that your calc executable under Windows is not usable.
+
+5. make install target=Cygwin
+
+   NOTE: This step is optional.  While calc is usable at the top of the source code directory
+         of calc, installing calc may be of benefit so you can use calc elsewhere on your system.

+developer to install a Linux virtual machine.  Nevertheless, a Windows 11
+user might want to use the Microsoft Windows Subsystem (WSL) for Linux:

+ *      but that is a long way off.  One of the main reasons why MAJOR_VER
+ *      might incremented is if fundamental calc data objects (such as when ZVALUE
+ *      or NUMBER or COMPLEX need to change) that would cause an incompatibility
+ *      with existing hardware accelerators that are using fundamental calc data objects.
+ *
+ * MINOR_VER
+ *
+ *      The MINOR_VER changes when there are incompatible changes to the calc library
+ *      or calc custom library.   The MINOR_VER might change if we need to make a major
+ *      change to the math engine.  For example, when the way 0^x was evaluated, we
+ *      changed MINOR_VER from 13 to 14.
+ *
+ * MAJOR_PATCH
+ *
+ *      The MAJOR_PATCH changes when there is an update to the calc library
+ *      or calc custom library.  For example, the MAJOR_PATCH might increment when there
+ *      are new builtin functions available, or when there is a change to how existing
+ *      builtin functions process arguments.
+ *
+ * MINOR_PATCH
+ *
+ *      The MINOR_PATCH changes whenever there is any change in the calc release.
+ *      For example, when the documentation changes, the MINOR_PATCH will increment.
+ *      Moreover, when we are working towards a new production release,
+ *      bug fix and improvement updates will cause MINOR_PATCH to increment.

Landon Curt Noll	f4f19f21dc	Add config("complex_space") to control spaces around + or - in complex values 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").	2022-12-04 00:53:15 -08:00
Landon Curt Noll	348f3ed427	Clarified -a and -f in calc man page Clarify in the calc man page, the relationship between -q and calc start scripts such as the ~/.calcrc file. Fixed in the calc man page, the issue of -f not implying -q.	2022-12-03 16:36:46 -08:00

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").	2022-12-03 14:39:25 -08:00

Landon Curt Noll	0d99ba54d8	Change default to print space after the approximation tilde 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.	2022-12-03 12:22:55 -08:00
Landon Curt Noll	83adfaa720	Removed compiler confusing setjmp() call In pseudo_seed(), we removed a call to setjmp() that was only there to add more information to mix into the seed. For compilers such as gcc that used -Wclobbered, the call to setjmp() gave the impression that the hash_val might be clobbered by a longjmp(). Where there is no longjmp() that would use the previous setjmp(), the gcc compiler has nil ways to notice that. So to avoid confusion we removed the setjmp() call. Thanks to <GitHub user mattdm> for raising this potential concern.	2022-12-03 10:47:05 -08:00
Landon Curt Noll	ef6a30c9c9	Fixed how the original TTY state is preserved In find_tty_state(), we changed how we expand fd_orig as an original pre-modified copy of fd_setup. We realloc the fd_orig array and copy the fd_setup into it first, before touching the fd_setup array.	2022-12-03 10:25:43 -08:00
Landon Curt Noll	3aaad95443	Fixed a use after free bug Fixed a -Wuse-after-free warning that identified a call to realloc() in find_tty_state() could move the fd_setup array. Thanks goes to <GitHub user mattdm> for reporting this bug!	2022-12-03 10:10:21 -08:00

Landon Curt Noll	d91ace6091	Release v2.14.1.2 The following are the changes in this release: Restored use of the #define FPOS_POS_LEN symbol. This refers to the length of the __pos element (if the __pos element exists), the fpos_t type (if that type exists). Changed SWAP_HALF_IN_FILEPOS(dest, src) mato to use FILEPOS_LEN Little Endian when FILEPOS is a simple scalar type (i.e., HAVE_FILEPOS_SCALAR is defined). Changed #define HAVE_FPOS to HAVE_FGETSETPOS. Corrected comment in have_fpos_pos.h. The HAVE_FPOS_POS symbol was NOT related to fgetpos & fsetpos but rather if we we have an __pos element in FILEPOS. Changed #define HAVE_NO_FPOS to HAVE_NO_FGETSETPOS. Improved comments in have_fpos_pos.h to show why and how HAVE_FPOS_POS, FPOS_POS_BITS, and FPOS_POS_LEN were defined or undefed. Changed showfiles builtin to print sizes cast to (long int) with the "%ld" printf format to avoid implementations that do not support the "%lld" printf format specifier. Renamed have_fpos.h to have_fgetsetpos.h. Renamed CALC_HAVE_FPOS_H to CALC_HAVE_FGETSETPOS_H. The make install and the olduninstall rules remove the any old have_fpos.h that was previously installed. Added swap_HALFs(dest, src, len) function to byteswap.c. Calc can now handle Big Engian file position sizes that are a multiple of BASEB bits in length. Before handle Big Engian file positions could only be 32 and 64 bits in length. This will allow, for example, a Big Engian file position size of 128 (assuming that 128/BASEB is is an integer). Temporary workaround for musl libc systems such as gentoo Linux that allows them to compile calc and successfully run the regression test.	2022-11-29 13:10:33 -08:00

Landon Curt Noll	b97093e58c	Fix calc man page \-escape, add cal/comma.cal Fixed a \-escape bug in calc(1) man page. Added cal/comma.cal: Convert numbers into strings with 3-digit group and integer-fraction separators. If the value is an integer, the integer-fraction separator is not used. str_comma(x, [group, [decimal]]) Convert x into a string. If group is given and is a string, group will be used as the 3-digit group separator, otherwise the default 3-digit group separator will be used. If decimal is given and is a string, group will be used as the integer-fraction separator, otherwise the default integer-fraction separator will be used. The decimal and group arguments are optional. set_default_group_separator(group) Change the default 3-digit group separator if group is a string, otherwise the default 3-digit group separator will not be changed. Return the old 3-digit group separator. set_default_decimal_separator(decimal) Change the default 3-digit group separator if decimal is a string, otherwise the default integer-fraction separator will not be changed. Return the old integer-fraction separator. print_comma(x, [group, [decimal]]) Print the value produced by str_comma(x, [group, [decimal]]) followed by a newline. If the str_comma() does not return a string, nothing is printed. The decimal and group arguments are optional. The value produced by str_comma() is returned. fprint_comma(fd, x, [group, [decimal]]) Print the value produced by str_comma(x, [group, [decimal]]), without a trailing newline, on file fd. If the str_comma() does not return a string, nothing is printed. If fd is not an open file, nothing is printed. The decimal and group arguments are optional. The value produced by str_comma() is returned.	2022-06-20 18:25:12 -07:00
