prep CHANGES for the next release of calc

removed use of have_memmv.c and HAVE_MEMMOVE, prep for version 2.15.1.2
Removed use of HAVE_MEMMOVE as well have_memmv.c. Removed the building and including of have_memmv.h. Removed the memmove() function in blkcpy.c, used when HAVE_MEMMOVE was NOT defined. The libc memmove(3) function as defined by <string.h> is now required to compile calc because the replacement code in blkcpy.c q was problematic, especially when regions overlap. The HAVE_MEMMOVE make symbol was removed from Makefile.config. Thanks to GitHub user @skeeto for reporting this problem.

+The following are the changes from calc version 2.15.1.2 to 2.15.1.2:

+    blkcpy.c q was problematic, especially when regions overlap.
+    The HAVE_MEMMOVE make symbol was removed from Makefile.config.
+    Thanks to GitHub user @skeeto for reporting this problem.
+
+
+The following are the changes from calc version 2.15.1.1 to 2.15.1.1:
+
+    Change Makefile.config to, if not using not HomeBrew, then try to
+    detect macports and/or using /opt/local/{lib,include}.
+
+    Put full date range (1989-2025) of calc source into version.h.
+
+    Version 2.16.0.0 will form the basis for the calc v2 to calc v3 fork.
+
+
+The following are the changes from calc version 2.15.0.7 to 2.15.1.0:
+
+    Converted all ASCII tabs to ASCII spaces using a 8 character
+    tab stop, for all files, except for all Makefiles (plus rpm.mk).
+    The command `git diff -w` reports no changes.  There is no
+    functionality change in calc: only ASCII tabs to ASCII spaces.
+
+    Fixed trailblank.  It was pruning . in its find search.
+    Added check for ASCII tabs is non-Makefiles.
+
+
+The following are the changes from calc version 2.15.0.6 to 2.15.0.7:
+
+    Thanks to GitHub user @bambooleafz a critical bug (GitHub issue
+    #148 - https://github.com/lcn2/calc/issues/148) they identified
+    was fixed.
+
+
+The following are the changes from calc version 2.15.0.5 to 2.15.0.6:
+
+     Thanks to GitHub user @ashamedbit, a long standing memory leak in
+     zrandom.c has been fixed.
+
+
+The following are the changes from calc version 2.15.0.4 to 2.15.0.5:
+
+     make clobber now removes the legacy files: have_fpos.h, help/man,
+     and help/usage.  The latter 2 are now managed as help aliases
+     in help.c.
+
+     make install now removes the legacy files: ${HELPDIR}/man
+     and ${HELPDIR}/usage.
+
+     Fixed a problem where, when calc was linked with and uses GNU
+     readline then for any multi-line copy-and-paste, only the first
+     line is executed.  Thanks to GitHub user @malfisya for reporting
+     this problem, and thanks to GitHub user @gromit1811 for doing
+     the research needed to overcome deficiencies in the GNU readline
+     documentation, and for supplying the work-a-round to allow
+     multi-line copy-and-paste to work as expected!
+
+
+The following are the changes from calc version 2.15.0.3 to 2.15.0.4:
+
+    Fixed bug that caused calc to fail to compile filepos2z() in file.c
+    on little endian machines for the Debian apcalc package.  Thanks to
+    Martin Buck (m at rtin-buck dor de) for for fix.
+
+    Removed unused macros from zmath.h:
+
+        SWAP_B32_IN_HASH(dest, src)
+        SWAP_B16_IN_HASH(dest, src)
+        SWAP_B8_IN_HASH(dest, src)
+        SWAP_B32_IN_FLAG(dest, src)
+        SWAP_B16_IN_FLAG(dest, src)
+        SWAP_B8_IN_FLAG(dest, src)
+
+    When SWAP_HALF_IN_B32(dest, src), SWAP_B32_IN_FULL(dest, src),
+    SWAP_B16_IN_HALF(dest, src), SWAP_B32_IN_bool(dest, src),
+    or SWAP_B32_IN_LEN(dest, src), SWAP_HALF_IN_FILEPOS(dest, src)
+    is an assignment such as:
+
+        (*(dest) = *(src))
+
+    We now case the dest and src pointers to the proper type before
+    referencing and performing the assignment.
+
+    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.  Be sure to use ||'s between []'s
+    to avoid problems with legacy shell such as the Bourne shell. *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 following are the changes from calc version 2.15.0.1 to 2.15.0.2:

+    prompt builtin returns null in calc shell scripts unless -p is used
+    ===================================================================
+
+    Be careful when using prompt(str) while calc is being used as a
+    shell script.  Unless calc is run with the -p command line option,
+    the prompt builtin will fail and return null.  This is because when
+    calc is running as a shell script, calc will close stdin run in in
+    a non-interactive mode.
+
+    The following shell script will always print "got null" because
+    stdin will be closed by calc during startup:
+
+        #!/usr/bin/calc -q -f
+
+        n = prompt("Test> ");
+        if (isnull(n)) {
+          print("got null");
+        } else {
+          print("got " + n);
+        }
+
+     However the following shell script (note the -p before the -f in
+     the 1st line) will be interactive, prompt with "Test> " and print
+     the "got" result as expected:
+
+        #!/usr/bin/calc -q -p -f
+
+        n = prompt("Test> ");
+        if (isnull(n)) {
+          print("got null");
+        } else {
+          print("got " + n);
+        }
+
+    Note in the example above, the -p flag must be given before the
+    final -f command line flag.
+
+    A similar problem will occur if the calc shell script attempts
+    to read from standard input (stdin), unless the -p flag is used.
+
+    See "SHELL SCRIPT MODE" in the calc man page for more information
+    about -p and about the "shell script mode".

Landon Curt Noll	d9245844aa	removed use of have_memmv.c and HAVE_MEMMOVE, prep for version 2.15.1.2 Removed use of HAVE_MEMMOVE as well have_memmv.c. Removed the building and including of have_memmv.h. Removed the memmove() function in blkcpy.c, used when HAVE_MEMMOVE was NOT defined. The libc memmove(3) function as defined by <string.h> is now required to compile calc because the replacement code in blkcpy.c q was problematic, especially when regions overlap. The HAVE_MEMMOVE make symbol was removed from Makefile.config. Thanks to GitHub user @skeeto for reporting this problem.	2025-08-13 12:42:45 -07:00

The command `git diff -w` reports no changes. There is no functionality change in calc: only ASCII tabs to ASCII spaces. Fixed trailblank. It was pruning . in its find search.

Landon Curt Noll	bb3b861090	Release v2.15.0.5 The following are the changes in this release: make clobber now removes the legacy files: have_fpos.h, help/man, and help/usage. The latter 2 are now managed as help aliases in help.c. make install now removes the legacy files: ${HELPDIR}/man and ${HELPDIR}/usage. Fixed a problem where, when calc was linked with and uses GNU readline then for any multi-line copy-and-paste, only the first line is executed. Thanks to GitHub user @malfisya for reporting this problem, and thanks to GitHub user @gromit1811 for doing the research needed to overcome deficiencies in the GNU readline documentation, and for supplying the work-a-round to allow multi-line copy-and-paste to work as expected!	2024-02-01 20:45:42 -08:00

Landon Curt Noll	18cd1f9067	Merge pull request #139 from gromit1811/master Properly handle multi-line strings and newline returned by readline()	2024-01-05 09:51:47 -08:00
Martin Buck	43fc022dc8	Properly handle multi-line strings and newline returned by readline() Fix for #138 According to https://lists.gnu.org/archive/html/bug-readline/2024-01/msg00000.html it's OK for readline() to return multi-line strings and/or newlines in case of bracketed paste (enabled by default since readline 8.1) and also in other situations even though its documentation explicitly states the opposite. So we need to handle this properly in calc instead of just using the first line and dropping the rest: Split the string returned by readline() into lines and return line by line with each invocation of hist_getline(), each possbily adding a terminating newline.	2024-01-05 10:34:25 +01:00

Landon Curt Noll	1d37930d22	Release v2.15.0.4 The following are the changes in this release: Fixed bug that caused calc to fail to compile filepos2z() in file.c on little endian machines for the Debian apcalc package. Thanks to Martin Buck (m at rtin-buck dor de) for for fix. Removed unused macros from zmath.h: SWAP_B32_IN_HASH(dest, src) SWAP_B16_IN_HASH(dest, src) SWAP_B8_IN_HASH(dest, src) SWAP_B32_IN_FLAG(dest, src) SWAP_B16_IN_FLAG(dest, src) SWAP_B8_IN_FLAG(dest, src) When SWAP_HALF_IN_B32(dest, src), SWAP_B32_IN_FULL(dest, src), SWAP_B16_IN_HALF(dest, src), SWAP_B32_IN_bool(dest, src), or SWAP_B32_IN_LEN(dest, src), SWAP_HALF_IN_FILEPOS(dest, src) is an assignment such as: ((dest) = (src)) We now case the dest and src pointers to the proper type before referencing and performing the assignment. 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. Be sure to use \|\|'s between []'s to avoid problems with legacy shell such as the Bourne shell. 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.	2023-12-21 05:52:06 -08:00
Landon Curt Noll	60698d2130	fix Makefile for legacy shell The top level Makefile needs to use multiple []'s between \|\|'s to not cause problems for legacy shells such as the Bourne shell. For example: ```make -${Q} if [ -z "${MANDIR}" ] \|\| [ ! -s calc.1 ]; then \ ... -${Q} if [ -z "${CATDIR}" ] \|\| [ ! -s calc.cat1 ]; then \ ```	2023-12-21 05:44:19 -08:00
