CHANGES MADE TO MATHOMATIC 15.2.0 TO BRING IT UP TO THE NEXT VERSION:
All makefiles were improved. Library test/example program is renamed to "testmain".
Package maintainers please take note: support for the DESTDIR environment variable was
added to the makefiles; for proper operation when packaging version 15.2.1 or higher,
please remove any patches for missing DESTDIR support.
m4 Mathomatic should work now when included in the Mathomatic package (make m4install).
Thank you for packaging Mathomatic! If I did anything wrong, please let me know.
8/26/10 - Added the -e option, which processes mathematical expressions and Mathomatic commands
instead of input files on the shell command line. For example, entering
"mathomatic -eq 2+3" gives "answer = 5". This functionality has been requested
many times by Mathomatic command line users. A complete example:
CHANGES MADE TO MATHOMATIC 15.1.6 TO BRING IT UP TO THE NEXT VERSION:
Minor improvements were made to the user documentation.
8/22/10 - Removed "Complex number roots approximated" warning message, since this happens often.
Capitalized E, I, PI, and Pi are now accepted as the universal constants e, i, and pi,
without needing to enter "set no case". This allows Mathomatic to easily
accept Mathematica style expression input.
m4 Mathomatic now additionally accepts Mathematica style capitalized function input.
matho and rmath now display elapsed, CPU, and system times in seconds upon exit.
8/23/10 - Fixed #equation-number entry at the main prompt to always work and allow an expression
or equation following on the same line to be entered at that equation space.
For example: "#10 y=1/x" will work now;
previously only worked if equation space number 10 was previously allocated and used.
The way it works is: all equation spaces up to and including number 10 are allocated,
if not already allocated, upon entry of "#10".
Equations spaces are allocated with the memory allocator malloc(3).
CHANGES MADE TO MATHOMATIC 15.1.5 TO BRING IT UP TO THE NEXT VERSION:
7/26/10 - Disabled ncurses call for auto-color detection when CYGWIN is defined while
compiling the source code, due to a reported problem of readline failing with
ncurses in Cygwin.
7/28/10 - Disabled readline history save file for the Cygwin port,
because it is a filename that starts with a period.
7/31/10 - Added "set fractions_display" option, to allow disabling the automatic conversion of
fractions like .5 to 1/2 for display.
Developer requested and useful in the symbolic math library,
when numerical fraction output isn't wanted.
8/01/10 - Fixed a memory leak when ignoring the output string in the symbolic math library.
8/04/10 - Preserve overflowed powers like 2^2222 rather than aborting with an error message.
Allow simplification of math like 2*2^2222 and 2/2^2222.
8/08/10 - matho-primes runs twice as fast with the -ffast-math gcc compilation option,
which is now enabled by default. Don't try -ffast-math with the main Mathomatic
program though, because then Mathomatic won't work properly.
CHANGES MADE TO MATHOMATIC 15.1.4 TO BRING IT UP TO THE NEXT VERSION:
Many minor tweaks and improvements.
7/03/10 - Makefiles and compile scripts were corrected and enhanced
per http://www.gnu.org/prep/standards/
7/06/10 - Changed all "#if true" and "#if false" conditional commenting to "#if 1" and "#if 0"
in the C source code, thanks to Min Sik Kim of NetBSD pkgsrc.
CHANGES MADE TO MATHOMATIC 15.1.3 TO BRING IT UP TO THE NEXT VERSION:
All of the Unix man pages and user manuals for Mathomatic were fixed.
The compare and "solve verify" commands now simplify more thoroughly with "repeat simplify"
for better expression equality determination.
6/17/10 - Greatly improved file operation error reporting by using the perror(3) function.
6/18/10 - Fixed categories in "icons/mathomatic.desktop";
Mathomatic now goes under valid categories, mainly Education.
CHANGES MADE TO MATHOMATIC 15.1.2 TO BRING IT UP TO THE NEXT VERSION:
6/6/10 - I made mistakes in the improvement to the simplify command of version 15.1.2,
the original working simplify logic of version 15.1.1 is now restored, sorry.
CHANGES MADE TO MATHOMATIC 15.1.1 TO BRING IT UP TO THE NEXT VERSION:
A general cleanup was done.
A small improvement was made to the final result of the simplify and fraction commands.
Showing intermediate results in the calculate, sum, and product commands is now done with "set debug 1".
5/28/10 - Added "tests/collatz.in", the Collatz conjecture as an automatically computable equation.
CHANGES MADE TO MATHOMATIC 15.1.0 TO BRING IT UP TO THE NEXT VERSION:
Code and documentation cleanup.
5/21/10 - Added "primes/matho-sum", a utility that sums its command line arguments or standard input.
Use "matho-primes 0 2000000 | matho-sum" to find the sum of all primes less than 2,000,000.
Solves Project Euler problem #10: http://projecteuler.net/index.php?section=problems&id=10
5/23/10 - Primes (') are allowed in variable names now, if not using the symbolic math library, so that the
derivative, integrate, and nintegrate commands can change the dependent variable to y', y'', etc.
This can be turned on in the symbolic math library by the command "set special_variable_characters='".
Non-alphanumeric characters in variable names are now converted to underline characters (_)
when exporting to a programming language or to a different program.
CHANGES MADE TO MATHOMATIC 15.0.8 TO BRING IT UP TO THE NEXT VERSION:
5/10/10 - Added "help constants" command.
5/11/10 - Integer variables are now specified by using a variable name that starts with "integer",
like "integer1", "integer_x", etc. Currently only the modulus operator "%" checks
for integer variables, to help with simplification.
5/12/10 - Corrected the output string type of the symbolic math library API. It was erroneously declared
as type "const", possibly causing a memory leak.
5/13/10 - Moved and adapted "makefile.lib" to "lib/makefile", so the symbolic math library build is isolated.
Previously "make clean" was required between different builds. All makefiles require GNU make now.
CHANGES MADE TO MATHOMATIC 15.0.7 TO BRING IT UP TO THE NEXT VERSION:
4/26/10 - Allow "make pdf" to generate PDF documentation from the HTML documentation with htmldoc.
Please read the comments in the makefile for all available options.
4/29/10 - For every makefile, CFLAGS has been modified to include OPTFLAGS as required by the Fedora Linux
build system, and OPTFLAGS defaults to the optional gcc specific flags like optimization.
In the symbolic math library, made available the equation number of the result of calling the API,
if also stored in an equation space. The result equation number is stored in the global "result_en".
Useful if you want to know where the result was stored, to act on it with further commands.
CHANGES MADE TO MATHOMATIC 15.0.6 TO BRING IT UP TO THE NEXT VERSION:
Corrections and improvements to the documentation were made.
4/3/10 - Vastly improved the "factor number" user interface, now factors integer expressions like 2^32-1.
"factor number" is disabled in library mode.
4/13/10 - The real and imaginary commands no longer fail when the expression is not complex,
just a warning is given.
4/14/10 - Changed normal display of "-1*" to "-", for prettier 2D expression output,
so things like "-a" display properly, not as "-1*a".
CHANGES MADE TO MATHOMATIC 15.0.5:
1/28/10 - Added a Python utility called "primorial" to the Prime Number Tools install
that multiplies together the results of matho-primes, displaying the primorials
of the integers given on the command line.
3/18/10 - Changed author email address to "gesslein@linux.com".
3/23/10 - Catch SIGHUP and SIGTERM signals for proper termination of the Mathomatic program;
readline was messing up when Mathomatic was terminated by closing the shell window.
The plot command now always plots expressions with grid marks displayed for reference.
CHANGES MADE TO MATHOMATIC 15.0.4:
1/21/10 - In the makefile, changed the HTML man page generator back to rman because
groff HTML output looks really bad and rman allows linking to other man pages.
groff is no longer used.
1/24/10 - Fixed "make m4install", the installed rmath and matho programs weren't working.
1/27/10 - Added GNU LGPL license notices to every C source file with a copyright notice,
for proper protections.
CHANGES MADE TO MATHOMATIC 15.0.3:
1/9/10 - Fixed a problem only in the version 15.0.3 makefile, where it didn't respect
the CC environment variable set by the user, instead it always used "gcc"
as the C compiler.
CHANGES MADE TO MATHOMATIC 15.0.2:
12/27/09 - Moved get_screen_size() from main.c to am.c because it is used in the library when
compile-time options UNIX or CYGWIN are defined.
Thanks to Cygwin port maintainer Reini Urban for noticing and fixing this problem.
Defining UNIX or CYGWIN in library mode is not recommended.
12/31/09 - Added code to allow any command to be preceded by "repeat", which sets the
repeat flag for the following command. Most commands ignore the repeat flag.
1/1/10 - Ported divide and roots commands to be repeatable. Also repeatable are the
calculate and eliminate commands.
1/2/10 - Allow Taylor series computation even if the specified differentiation variable
is not found in the expression, giving a warning.
Ported simplify command to be a repeatable full simplify; that is, typing
"repeat simplify" repeatedly runs the simplify command until the result stabilizes
to the smallest size expression.
1/7/10 - Thanks to pretty C code submitted by Simon Geard,
the code and variables commands have been made much more readable.
1/8/10 - Made Mathomatic easier to compile under Solaris, thanks to Michael Pogue of Sun.
Fixed failure to compile under BSD Unix when compiling with readline support.
CHANGES MADE TO MATHOMATIC 15.0.1:
12/19/09 - The last few versions fix the ugliness caused by the GCD factoring change made on 6/22/09.
Today's change factors out the numerical GCD of rational coefficients as needed to simplify.
Most simplification results should be beautiful and the simplest possible again now,
without the misleading observed magnitude caused by always factoring out the GCD,
which was why the change of 6/22/09 was made.
CHANGES MADE TO MATHOMATIC 15.0.0:
12/12/09 - Fixed a problem with the -q (quiet mode) option being ignored if the session options
were ever saved with the "set save" command.
12/13/09 - Added code to allow Mathomatic output to be redirected by default.
Fixed the derivative command to be successful even when the result is 0,
when compiled as a library.
12/14/09 - Added ability to log symbolic math library results, and made command behavior
more consistent in the library by always returning the final result string.
12/16/09 - The factor command now factors more by factoring out the GCD of rational coefficients.
CHANGES MADE TO MATHOMATIC 14.6.3 TO BRING IT UP TO 15.0.0:
Cleanup and more bug fixes.
11/26/09 - Added detection of the terminal's ANSI color availability, when readline is enabled.
11/28/09 - Added detection of divide by zero and NaN when using the "solve verify" command,
for more correct results.
Solving now factors out the GCD of rational coefficients, for improved results.
The fixes today are from errors solving equations like (2*x/(x - 3)) + 3 = 6/(x - 3)
11/29/09 - Disallow the variable named "nan". NaN cannot be directly entered into Mathomatic.
11/30/09 - Added shell scripts "t" and "tests/t" to easily test Mathomatic by typing "./t".
12/2/09 - The fraction command now factors out the GCD of rational coefficients like the
solve command does, so that coefficients in algebraic fractions become integers.
The GCD verifying routine was perfected by making it very strict, like it should be.

Important changes since 14.4.4:
- General cleanup and addition of helpful descriptive text.
- Cleanup and major bug fixes.
- Enhanced code for use with iPhone.
- Minor corrections and additions to the code and documentation.
|
|
|
|
Changes since 14.3.6:
- Perfected the user interface for the sum, product, and integrate
commands.
- Restored initial full simplify in the limit command for better
results, that was unintentionally removed in version 14.1.0.
- Fixed an endless loop in simplification; results look better, too.
- Added "set save" command, which makes all current session options
permanent, by saving them in "~/.mathomaticrc". "set no save"
removes this file.
- Added "mathomatic -s" option, which stands for secure mode. This is
a run-time option that disallows shelling out and writing files, and
was created for use on public servers that can't use the SECURE
compile-time define.
- Doubled the default maximum mathematical expression size to allow
larger expressions.
- A fatal compilation error when compiling with defines other than
UNIX was fixed.
- Slight improvement made to simplification; results are more simple
and stable.
- The maximum integer that can be factored has been raised from 14 to
15 decimal digits.
- Small fix made to fraction command and "simplify fraction" for
better looking fractions.
- Added a "simplify quickest" command option, which does no
unfactoring nor factoring.
- Made full simplification more efficient and simpler by cutting out
unnecessary loops.
- Improved the divide command and enabled its use in the symbolic math
library. Enabled code and variables commands in library, too.
Currently, library output of these 3 commands can only be gathered
by redirecting to a file.
- Added "set autoselect" and "set auto" options. Use "set no auto" to
always store entered expressions into equation spaces, unless it is
a command.

Changes since 14.2.7:
12/23/08 - Simplified makefile.
12/26/08 - Fixed rules for simplifying "(x^n)^m" so "misc/john.in" and
others simplify better. Works similar to Maxima now.
12/27/08 - Numeric GCD now properly returns the other parameter, if
either parameter is 0. Renamed "misc/polyroots.c" to
"misc/roots.c" and simplified this example code.
12/30/08 - Added "update" script, which updates the function
prototypes in "cproto.h".
1/1/09 - Optionally factor out the gcd of integer coefficients when
improving readability, for example: 6x+4y becomes 2*((3*x) +
(2*y)). This is now the default.
1/13/09 - Added descriptions of all interesting math scripts in
"tests/README.txt".
1/16/09 - Allow nintegrate and "integrate definite" commands in the
symbolic math library; the bounds are specified in the two
equation spaces following the current equation.
1/18/09 - Made expression and equation entry always consecutively
numbered equation spaces, unless memory is exhausted.
1/19/09 - Made consistent list command output with only one newline
after each equation space.
1/21/09 - Fixed erroneous doubling of parentheses display when solving
and showing steps with "set debug 2".
1/22/09 - Added -b option, to conveniently set bold color mode from
the command line.
1/25/09 - Improved looks of eliminate command by not solving if
equation is already solved.
2/3/09 - Table of contents was added to the Mathomatic User's Manual.
2/5/09 - Added display of any numerical fractions when calculating or
using calculate command; for example, entering "1/2+3/8" now
results in "answer = 0.875 = 7/8".
2/6/09 - Removed erroneous lsqrt() routine obtained from Wikipedia, so
that matho-sumsq works properly now.
2/7/09 - Disable pause command when appropriate (when input not a tty
and for symbolic math library).
2/8/09 - Polished up educational example scripts in "tests" directory.
2/11/09 - Entry of a function now results in "Named functions
currently not implemented" error message.
2/12/09 - Bugfix to matho-primes and added "misc/limits.c".
2/15/09 - The fraction command was fixed to give better results. "set
display2d" flag now no longer affects any results at all, it
only affects 2D output mode.
2/17/09 - Renamed -h (HTML) option to -x, -h is now the help option.
Added -w option to set wide output mode.
3/9/09 - Found the correct formulas for solving the general cubic
equation on Wikipedia, so "tests/cubic.in" always gives
correct answers now.
3/12/09 - Tweak made to simplify result beautifier: factoring priority
only given to real variables now, special constant variables
pi#, e#, and i# have no effect and behave like any constant
now.
3/15/09 - Corrected and improved parse_complex() C function for more
complex number functionality and a bug fix.
3/18/09 - Added "set negate_highest_precedence" option, which allows
the negate operator to be the lower precedence of times and
divide, like it is in Maxima and most other math programs.
3/24/09 - Made "set no autosolve" mode more useful by making it solve
if a solve variable is entered with an equals sign. This
allows easy entry of both single variable expressions (with
no =) and solve variables (with =) while in this mode.
3/27/09 - Selecting equations by entering the equation number was
returning with error if the equation space was empty.
Fixed, you can now select any previously allocated equation
space.

BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
