Things To Do...
- The decimal places is governed by the number of rails to right of
decimal marker. But if there is a big difference between the base and
the display base, this should be govered by the logarithm also. E.g.
The Babyloninans used 3 decimal places base 60 to figure out sqrt(2).
It would be nice to show the proper decimal places for base 60 abacus
when showing base 10 digits on the display. ceil(r*log(60)/log(10))
more places (where r = rail decimal places). Currently, it does not
look right to move beads to right of decimal point and not see a
corresponding change in the number in display sometimes.
- Add features to new Android App version. Current major problem is
that the animation did not port from applet/application to Android.
- "xabacus really bad": (Oow got ripped by a review...)
Not my idea to distribute C version without Motif, but the intent was
that its supposed to be minimalistic, sort of like oclock, i.e. a
retro-look. I kind of like it, but its not for everybody.
- "xmabacus app is out of date":
Added a few new things in 7.7.1 (see below) but kept Motif interface,
not really specific on what was out of date. Possibly its time to
adopt Gnome or KDE but do not yet see the value added over available
Java version. Also a big problem I see is that these other libraries
keep changing. Another thing is that Motif works great with Xt Widgets
which allows you to group widgets together easily like in "Lee's Abacus"
where I have a main abacus widget grouped together with 2 auxiliary
abacus widgets. I am not sure how I can port this feature.
- What graphics in menu would help?
- The calculator portion does not work for big numbers, i.e. where
one can type in math operations and see the abacus perform, e.g.
1,000,000,000,000,000.0+1. Now use BigDecimal for calculations for
Java but problem remains, probably due to some remaining long/double
dependencies.
- When displayBase != base calculate with strings instead of
"long long". I.e. the number of rails can be large if displayBase =
base, but may error out when this is not true for a large number of
rails. Now use BigDecimal for calculations for Java but problem
remains, probably due to some remaining long/double dependencies.
- Allow for
locale
to use "," for "." and vice versa.
It might be confusing to change this if one actually wanted to try
different locales, e.g. Danish Abacus.
- Handling of negatives would be nice (work started with complement
function).
- "Demo" and "Teach" have beads and rail highlighted to make clear the
current position of calculation for digit; should this be extended to
highlight a printed digit in a result? (For Java: JTextField will not
work, need to change to JEditorPane).
- Developing Custom Draw Controls i.e. NM_CUSTOMDRAW. Would this help
make "widgets" in Windows (so Lee's Abacus could run there)?
customdraw
- Added gettext for languages. It seems like Motif just uses ISO8859-1
encoding and does not not handle UTF-8 non-ascii characters well, the
work around was to use escape sequence for each non-ascii letter. (More
languages translations would be nice).
./configure --enable-gettext
LANGUAGE=fr_FR; export LANGUAGE
make msgfmt
- Teach strings at command-line for vanilla X so do not need Motif/Athena.
- Fukutaro's method for sqrt is faster then Lee's method and should
be adopted by teach mode. http://totton.idirect.com/soroban/katoSq/
Similarly https://xlinux.nist.gov/dads/HTML/cubeRoot.html
- Have a way to have buffer rails (beads in middle of rail is an
option) so as to have registers similar to Lee's Abacus but as one
long abacus.
- For Lee's Abacus should have way of synchronizing options like
format or stuff like xabacus -group -groupSize 2 (normally 3)
- More detection of limited rows for calculation. Probably more
examples where teach mode fails for simple calculations when decimal
offset or limited number of rails. I have fixed cases I have seen.
- Hard coded keys like 's' and 't', etc. may be confusing so should
be a way to turn off.
- Change granularity in teach mode. I.e. skip teaching addition for
multiplication.
- Implement undo and redo for teach and demo mode.
- Athena: sometimes gives BadGC on Cygwin for scrollbar or format
menu.
- JavaScript teach mode needs more highlighting to show its finished.
- setDecimalPosition offset by 1 in Java version when initialized if
need special rails like quarter. X version OK.
JavaScript - Latest Tweaks...

If display base != base of abacus now should have appropriate
fractional portion using log(abacusBase)/log(displayBase)
as a guide.
Added some rounding as it was taking floor value where the
display base != base.
These two things were noticeable on Base 2 Abacus and Sumerian
Abacus.
8.3.6:
Complement now works with undo and redo.
Dropping Babylon Watch idea, as I see that the Sumerians and
the early Babylonians did not generally work with groups of
five. Added support for a Sumerian Abacus which is closer
to what they probably had, if they had one.

8.2.9:
Fix teach to make Chinese Abacus base 16 algorithm more generic
to work with other bases and bottom bead count.

Broke teach mode by adding feature in 8.1.5 that did not have all
references in MessagesBundle.properties. Feel free to email me
with translations.
Spelling of Schoty corrected again.
Updated references to website to https. https://www.sillycycle.com
8.2.3:
Added new group color scheme and used for Mesoamerican abacus.
Fix for frame icon broken previously.
8.2.2:
Fixed a Roman rail setting.
Dropped support for applets :(. This was dropped because applets are
deprecated and for security. Now only runs as a application. (Some
puzzles are available in HTML5 and JavaScript to run directly from
web. Let me know if some favorite feature or puzzle not available
on HTML5 version and I will see if I can remedy.)
Sound now uses ".wav" format, ".au" format was dropped as there seemed
be less support for ULAW audio files.
Fixed sound menu item check box.
Added support for more icon sizes.
8.1.7:
Changed slider to spinner as it takes up less room.

Added rail shading.
8.1.5:
Fix for topSpaces and topNumber, can now be set to 0 in generic
mode.

Adding an experimental feature, property files for locales. Its only
experimental and used only in teach mode.
Fixing special decimal position when not enough room for special
rails.
Spelling of Suanpan, Jupan, and Schoty corrected.
Updated look of "X" and "<>" in medieval abacus.
8.1.4:
Teach fix for (division or root) and piece rail.
Teach fix for for lower bounds of rails with cube roots.
Fixed shifting of rails for teach or demo and piece rail.
Exiting from demo and teach now cleans all rails of highlighting,
even auxiliary rails.
8.1.3:
Quarter percent now independent of piece rail for quarter and
twelfths.
Fix a long standing bug when adding under teach and piece rail
is set.
Fixing when subdeck and changing format.
8.1.2:
When showing demo moves it now highlights the rail being moved.
Added GUI interface for Ancient Roman in display and Modern Roman
on rails (not historical), also will show fractions in Latin.
Turn off Roman Numeral display when using decimal fractions.
Subrails and quarters now mapped in Roman Numerals (by factor of
3, not historical). (Symbols on right are not correct but not
correct for subdeck eighths either.)
Adding/removing sign no longer clears subrail.
Removing subdeck or format left extra values and beads.
8.1.0:
Fixed demo where end of lesson was being cut off. Added delay.
Added another book from Abacus Guide. Only first few chapters
and examples so far. (Not available in fallback mode.)
8.0.9:
Demo now in an xml with a fallback if it can not be found.
Updates to Roman display.
Old website http://www.tux.org/~bagleyd died, shifted code base to
new website http://www.sillycycle.com

Moved demo to xml file.
8.0.3:
Medieval sound fixes.
8.0.2:
Many bugs fixed for the new Counter including highlighting.
8.0.1:
Medieval Counter added. Click left of X to add or right of X to
subtract. Middle of line is a counts as 5 (for base 10).
8.0.0:
Added drip sound for format change.
Moving the decimal point needs a select and a release to a different
point on "tape". Now behavior more consistent with a real abacus.
Also consistent with Android, as a big finger moving beads would
too easily move decimal point.
Scalable frame.
7.7.3:
Reorganized icons directory.
Separating to smaller Java files to help port to Android.
7.7.2:
Fixed bug for Lee's Abacus, putting a value in a field then erasing
with a return would not clear beads.
7.7.1:
Beads were drawing to far right when vertical with two decks.
Added scrolls to most help dialogs. Dialogs now use swing.
Submenus for controls.
Moved sliders for base into menu. Added delay slider in menu.
Label added like Motif version "Format:" for ComboBox.
Labeling of Auxiliaries and Primary. It should disappear when prompt
is used. Color of text is 2 shades darker than the default bead.
This is only done for Lee's abacus.
Made "Generic" mode disabled in menu (only can use if set at start).
Radio buttons added for museum choice, disabled in all but Roman
Hand-Abacus.
Added check boxes to menus. Subdeck and eighth enabling etc
kind of complicated as it needs exactly 2 places for decimal,
twelfth (or quarter), and slots (Roman). I hope I got all the cases.
Fixed problem where bottom bead does not work with arrow.
Not that it mades sense, but 12ths added to broken bar example
caused not enough room for beads.
7.7.0:
Added mouse scroll. Also arrow keys with mouse work similarly now.
Added a line so ComboBox does not get cut off by Canvas.
Abacus canvas now has default focus when applet comes up.
Abacus control left/right (or if vertical up/down) changes number of
rails (synchronized with slider).
7.6.8:
New test mode to help teachers give tests on the Abacus. Now with
timeout feature.
Took out JPopup and put in JMenu stuff from application. Would have
done before but did not realize Applet needs to be JApplet for this
to work.
Added border for htmls thanks to
http://www.squidoo.com/html-backgrounds-
Added Attach/Detach thanks to code snippet Code Ranch and JavaKB by
Brian Pipa.
Also found something in stackoverflow from Alex for resizing JFrame.
Had to reorganize the shortcut letters:
v Roman Nvmerals (was m)
m Museum (was e)
e Eighth (was h)
h now used in attach/detach in Java html window.
Fixed an error when switching from eighths to twelfths.
Now have sound initialization only run on first try to make a sound as
I found sound initialization hangs on one of my systems.
7.6.6:
Cbrt in teach now works, try like "3u" (cbrt of 3).
It flashes now when reached final answer in teach mode.
7.6.5:
"2v" (sqrt of 2) in teach now works. Place decimal place appropriately
to give wanted precision.
7.6.3:
Highlighting of beads added in teach mode.
7.6.2:
Highlighting of rail added in teach mode.
7.5.5:
teach division information: remove redundancy for single digit calc
more teach information for add/subtract
7.5.4:
Fractional fix for division.
Teach mode base fixes: division, multiplication, lee.
Teach mode: fixes for error handling.
7.5.3:
Teach mode: bug fixes and better error handling.
Lee's abacus: handle teach mode when formats are different.
Resynced C and Java code, man pages should closely relate to both
now.
Started on sqrt and cbrt but have trouble understanding the method
in "How to Learn Lee's Abacus" by Lee Kai-chen (which is using
a strange variant of Newton's method).
Started on colorizing "Teach" to make clear the current position
of calculation for digit and rail. Nothing to show for it yet,
but new "highlight" colors will be used for this.
7.5.2:
Division using teach now works.
7.5.1:
1/7 now works for long digits (only Java).
Found problem with borrow for subtraction and teach (e.g. 39-28).
Multiplication using teach now works.
7.5:
Cleaned up menu look.
Added "Teach" utility to allow teaching of addition and subtraction.
Tables are taken from "How to Learn Lee's Abacus" by Lee Kai-chen.
Generalized so bases should also work with "Teach".
Fixed bug in calculate when using quarters or quarter percents.
Changed name of flexible mode from "Other" to "Generic" and changed
default to be Chinese.
Moving beads when base was large for Russian or Danish format could
cause a false display of corruption error.
Put non-English names of Abacus in pull-down.
Added complement function, may be useful in future for negatives.
Added rightToLeft for "Teach". With it you can change from the
traditional left to right for addition and subtraction.
Java - Older Releases
7.4.2:
Panel info length was trying to be 4 times bigger than it should be.
Vary the images displayed depending on kind being used, do not have
all yet.
7.4.1:
Keyboard entry and gui were not working together.

findbugs and pmd changes.
7.3.8:
Fixed various corruption and overflows.
Fixed goof in ancientRoman.
7.3.7:
Allow latin for fractions when using Roman Numerals with -latin.
Allow signs on bars to be "modern" Roman Numerals with -modernRoman.
Allow older Roman Numerals to be displayed with -ancientRoman.
No group positions on abacus when anomaly is on.
7.3.6:
Allow "," for decimal point and "." for group separator. Probably,
should be done using locale but there are so many ways to configure
the abacus, I was not sure I should make an exception here and
configure it a different way.
Fixed bottom bead click which was 3 pixels off.
-pressOffset option added. Beads are now closer together.
Use option to access older way.
Beads are rounder with light bordering to distinguish beads easier.
7.3.5:
Calculation support when displayBase != base.
Commas should be ignored in calculations.
Implemented calculations for anomalies.
Calculation support up to base 20, which historically,
was the maximum base used. Babylonians used 60, but was a
conglomeration of base 10 and 6.
7.3.4:
Calculations turned off when there are anomalies present.
Calculations like 4! can now be done in auxiliary fields.
Fixed 4! = 23.99.
Changed cursor to hand pointer.
Added javadoc info.

7.3.3:
Constants changed.
Added script option: java -jar AbacusApp.jar -script=on
7.3.2:
gcj warning cleanups.
Abacus Demo upgrade to allow chapters.
7.3.1:
Updated action codes and synced Java and C code.
Added eighths ability for Roman Hand Abacus, as suggested by Stephen
Stephenson. Setup for UK Museum version may not work as expected on
FR and IT versions.
7.3:
Spawned off a Canvas.java from main java code.
Better keyboard interface code.
7.2.9:
Named fractions added for Roman numerals using 12ths and subdeck.
7.2.8:
Roman Hand Abacus fix for subdeck part 1/3 of 1/12 should really be
1/12 of 1/12 thanks to Ray Greaves .
7.2.7:
New bump.au sound and db lowered, thanks to
http://audacity.sourceforge.net to help clean the sound up.
Setting decimal a little off for vertical.
7.2.6:
Got the multiplication demo from xabacus to work on the Java
Lee's Abacus.
Option to format output to use commas so numbers can be read easier,
shortcut use "g" for group.
Made a Lee's Abacus.
Fixed an overflow if number entered in display is too large.
Implemented JavaScript applet quit option.
Now has left alignment so it will work cleaner with IE.
Application flashing removed.
Now use http://netpbm.sourceforge.net to generate images from xpm.
7.2.5:
Check for noninteger parameter input.
Roman subdeck to Russian error fixed (ffftb.04f).
Roman subdeck error fixed (ffftb.04b).
Roman fix for pieces and piece percents.
Russian to Danish fix for twelfths.
Added more debugging.
Assorted fixes for changing number of rails.
Danish fix for coloring percents when using twelfths.
7.2.4:
Minor resyncing of code with X/Windows version.
7.2.3:
Line feed fixes.
Cookies more readable.
JavaScript/Cookie code back in.
Ant build now fully supported.
Tan frame.
Danish Elementary School abacus added (teaching aid).
Do not know how its used, setup as:
clears when pushed left
lowest order beads at bottom
kept simple so decimal point is at bottom
Jar file now has a MANIFEST so it can run as an application if
downloaded.
7.2.2:
AWT to Swing... (I kind of liked AWT... but won over to get Mnemonics
to look right).
Fixed bug for signs and quarter percents and subdecks.
Changed definition of CARRY buffer from 2 to 1, fixed display bug.
Anomaly now works when carries are possible. Although there is no
historical abacus like this, its nice to remove this requirement.
Pieces and piece percents now use "+" on rail except Roman Abacus.
Right click clear fix (off by one).
Fix for calculation so will not get tripped by Roman Numerals if on.
Automatic calculation is back, do not know when I broke it.
Fix for random Roman Hand Abacus.
7.2.1:
Simplified code to switch to and from Russian abacus.
Redesigned rounded beads to always account for slots. I.e. a bead is
either an overlay of 2 circles and a rectangle if a wide bead or an
overlay of 4 circles and two rectangles (a cross) where there would
always be a flat edge along the width of a rail or slot.
7.2 and older:
Added on 3 subdecks with 4 beads.
./xabacus -roman -rails 10 -tpiece 2 -bpiece 6 -subdeck 3 -subbead 4
1/2,1/4,1/3 ounces column now work for a Roman Abacus. This
comes in two flavors, where possibly the simpler one, needs 3 decks
(where a single bottom column would be) (one known example in
museum in British Museum in London). In the other flavor, the
beads could stop midway on a single slot (in IMHO not a well defined
way) (two known examples one in Museum of the Thermae in Rome and
one in Cabinet des medailles, Bibliotheque nationale, Paris).
Type "e" or use Museum option to cycle through museum pieces.
Added older Roman Signs "|x| (((|))) ((|)) (|) c x |" on bar.
Also allow these signs to be Roman Numerals.
If anomaly, calculations are not allowed.
Switching from/to Russian with a negative was broken.
Added more sanity checks for configuration, or it could go into a
weird state.
Fixed for small beads and PC version, would not have rounded slots.
Fixed top level room and spaces if top pieces or piecePercents
greater than 2.
There were some cases where resizing the number of rails causes
the calculation to change unnecessarily.
Signed overflow fixes e.g. 50000000000*2=-5000 or
-100000000000 Chinese converted to Japanese.
Assorted tweaks discovered when porting code to Java version.
Moved Anomaly from "a" to "l" to be consistent with Java version.
Move bar problems with quarter percent.
Sign, quarter, and quarterPercent code all rewritten to be less buggy.
Quarter percents option for 1/4 Kopecks.
Use of "piece" instead of "quarter" for more variability. This now
allows a "twelfths" capability (Roman ounces) for Roman Hand Abacus.
Its pretty configurable (with the configuration file) so you can have
a range from halves to sixteenths (stock market pricing, pieces of
eight, etc), and possibly beyond if you want to get crazy.
New symbols on the bar for "-" for sign, "O" for pieces. If the base and
piece and format in Russian style set weird it could otherwise be hard
hard to read. O used because it was used on the Roman Hand Abacus.
Anomaly option for Mesoamerican Nepohualtzintzin Abacus. Basically a
JP Abacus in base 20 (3/4) where the columns left of the 2nd digit are
multiples of 360 (instead of 400). 4th column of unit beads would be
20x360. Bar marked with an "X" where the anomaly is. Note: this
is turned off if there are extra beads as in the Chinese mode or
Korean mode or this leads to even more unexpected anomalies.
AnomalySq option to make more Anomaly more configurable, now can have a
representation of time using hours, minutes, seconds. Babylonians are
responsible for that mess. Though they probably did not use an
abacus.
Vertical for proper Russian schoty (rotate xabacus clockwise 90 degrees).
Use "v" or menu to toggle.
Each bead that is a multiple of 1000 gets a darker color on Russian
Abacus.
build.xml
Synced up with X version. Does not do Lee's Abacus but most features
are there. All deprecations are now removed.
As long as the bases are equal... it can figure out pi...
enter p, e... enter e, 2v sqrt of 2, 3u cbrt of 3.
Also try 5! and 4.9! (related to gamma function).
Left and Right icons commented out, take up too much valuable room and
may be confusing.
Got rid of some deprecations and Xlints.
Initial conversion from C to Java by Sarat Chandran
.

Lots of language internationalization added for teach mode.
See README for --enable-gettext and msgfmt.
[Mar 20, 2022] V8.4.0:
Fix for compiling without Motif.
[May 23, 2021] V8.3.7:
If display base != base of abacus now should have appropriate
fractional portion using log(abacusBase)/log(displayBase)
as a guide.
Added some rounding as it was taking floor value where the
display base != base.
These two things were noticeable on Base 2 Abacus and Sumerian
Abacus.
[May 09, 2021] V8.3.6:
Complement now works with undo and redo.
Dropping Babylon Watch idea, as I see that the Sumerians and
the early Babylonians did not generally work with groups of
five. Added support for a Sumerian Abacus which is closer
to what they probably had, if they had one.
Restructured support for piece, piece percent, and subnet to
now all support [quarters|eighths|twelfths].

[Jan 31, 2021] V8.3.3:
Allow new color scheme for abacus found at the British Museum
from the 17th century.
[Dec 27, 2020] V8.3.2:
Noticed that Lee's abacus has the group and decimal separators
after a specified rail, so added an option to fix that
placeOnRail, off by default.
[Dec 11, 2020] V8.3.1:
Updated subtract operation to say borrow instead of carry.
[Nov 20, 2020] V8.3.0:
Swap 'e' and 'r' where 'e' now is for Enter in demo and 'r' is for

Fix teach to make Chinese Abacus base 16 algorithm more generic
to work with other bases and bottom bead count.
[Jul 10, 2020] V8.2.8:
Fix teach mode for Chinese Abacus base 16. Problem was that the
top factor not divisible by base, which broke algorithm.

Fix for Chinese Base 16 complement.
Drop display of decimal point if decimalPosition on rightmost rail.
[Mar 23, 2020] V8.2.5:
Added a pause popup after calculation is done in teach mode. The
reason being is that you can have a long calculation and may
be hitting return a few times and miss the solution. Does not
work if you hold it down however.
Having 3rd decimal place in right auxiliary and then teach mode of
was 25/3 giving error.
Added a undo and redo for regular manipulation.
[Jan 05, 2020] V8.2.4:
Vertical formatting available with "|" key or menu. Beads and rails
will now maintain their orientation when cycling through formats.
This seems better as window is frequently setup to for a certain
orientation.
Museum selection fix for windows.
Handle "4281829918390249v" or "728028431936u" better in teach mode.
Before it would get stuck and would not redraw screen if not
enough rails are available.
Spelling of Schoty corrected again.
Updated references to website to https. https://www.sillycycle.com
[Nov 30, 2019] V8.2.3:
Added new group color scheme and used for Mesoamerican abacus.
Fixed where -sign was not adding sign rail.
[Oct 09, 2019] V8.2.2:
Made the rails a little thicker.
Build on win32 can now use libxml2-2. make all-xml This is not the
default because it requires the xml dll libraries to be in path at
runtime. This is used for reading abacusDemo.xml.
Fixed demo in windows to start at the beginning. (Was starting on
second lesson).
Fixed windows code where quitting demo mode or teach mode might
leave magenta colored rails and beads.
[Feb 15, 2019] V8.2.1:
Fixed spinner to not wrap and be unlimited where appropriate.
[Oct 02, 2018] V8.2.0:
Removing strcpy and strcat calls by migrating to strncpy and strncat.
Added snprintf compile-time option. Did for all files except
AbacusT.c, (for teach mode) here it was reduced but not eliminated.
Fixed drawing especially for Roman Hand Abacus and Medieval Counter.
Fixed clearing decimal when changing format from Roman Hand Abacus.
Fixed problem pointed out by clang using uninitialized variables.
[Jul 21, 2018] V8.1.8:
Fixing sound installation.
Fixing potential some buffer overruns pointed out in mingw in
AbacusT.c.
[Apr 03, 2018] V8.1.7:
Updated to use spinner (using latest Motif ;) ).
[Feb 05, 2018] V8.1.6:
Added rail shading.
[Nov 16, 2017] V8.1.5:
Fix for railIndex, can now be set in generic mode.
Russian abacus the spaces were increased by 3.
Adding an experimental feature, configure --enable-gettext for
locales. Its only experimental and only used for teach mode. For
now Motif does not handle non-ASCII very well. Looking to just
handle a simple change first like French accents. Any examples
of handling this in Motif would be appreciated.
Spelling of Suanpan, Jupan, and Scoety corrected.
Updated look of "X" and "<>" in medieval abacus.
[Oct 15, 2017] V8.1.4:
Teach fix for (division or root) and piece rail.
Teach fix for for lower bounds of rails with cube roots.
Teach fix for presentation of groups for root operations.

Fix a long standing bug when adding under teach and piece rail
is set.
Windows now grays out options where appropriate.
[Aug 21, 2017] V8.1.2:
When showing demo moves it now highlights the rail being moved.
Added GUI interface for Ancient Roman in display and Modern Roman
on rails (not historical), also will show fractions in Latin.
Turn off Roman Numeral display when using decimal fractions.
Subrails and quarters now mapped in Roman Numerals (by factor of
3, not historical). (Symbols on right are not correct but not
correct for subdeck eighths either.)
Adding/removing sign no longer clears subrail.
Removing subdeck or format left extra values and beads.
Fixed eighth sensitivity issue in Motif menu.
[Aug 01, 2017] V8.1.1:
Valgrind helped find some definite memory leaks.
Show last move in lesson.
[Jul 17, 2017] V8.1.0:
Removed the lesson files and now use same abacusDemo.xml in Java port.
Added fallback code to use a static demo if can not read XML demo file.
Windows version always uses fallback, some issue with libxml2-2.dll
at runtime. The X version if compiled without libxml2 will also use
fallback to use static demo.
Added another book from Abacus Guide. Only first few chapters and
examples so far. (Not available in fallback mode.)
Updated sound configuration for X version. Uses a simple included
script play.sh, that is now used by default.
[Sep 03, 2016] V8.0.8:
Updates to Roman display.
Old website http://www.tux.org/~bagleyd died, shifted code base to
new website http://www.sillycycle.com
[Jan 18, 2016] V8.0.7:
Bases other than 10 broken since 8.0.0.
[Dec 12, 2015] V8.0.6:
Fixed the "wrench" look for X when showing anomalies.
Added group markers after last anomaly.
[Oct 22, 2015] V8.0.5:
Added small pointer for feedback when moving decimal point.
[Sep 28, 2015] V8.0.4:
Some lessons had some lines too long causing problem.
[Feb 24, 2015] V8.0.3:
Sound and install fixes.
Fix for switching from Chinese to Medieval and vice versa.
[Nov 28, 2014] V8.0.2:
Many bugs fixed for the new Counter including highlighting.
[Nov 18, 2014] V8.0.1: Not released
Medieval Counter added. Click left of X to add or right of X to
subtract. Middle of line is a counts as 5 (for base 10).
[Mar 18, 2014] V8.0.0:
Added drip sound for format change.
Moving the decimal point needs a select and a release to a different
point on "tape". Now behavior more consistent with a real abacus.
Also consistent with Android, as a big finger moving beads would
too easily move decimal point.
Scalable frame.
[Jan 20, 2014] V7.7.3: Not released
Reorganized pixmap directory.
[Jan 10, 2013] V7.7.1:
Fixed draw of diamond beads when vertical.
Added scrolls to help dialogs where needed.
"xmabacus difficult to use": criticism was not clear but added:
Submenus for controls.
Moved sliders for base into menu. Added delay slider in menu.
Motif has problems with sliders in menus so they are actually
in a pop-up.
Added toggles to many toggles to menu buttons.
Moved Learn stuff into menubar and base stuff into menu like
Java version.
Made "Generic" mode disabled in menu (only can use if set at start).
Added check boxes to menus. Subdeck and eighth enabling etc
kind of complicated as it needs exactly 2 places for decimal,
twelfth (or quarter), and slots (Roman). I hope I got all the cases.
Radio buttons added for museum choice, disabled in all but Roman
Hand-Abacus.
"xmabacus not all fields labeled": Primary and Auxiliaries are now
labeled. It disappears when prompt is used. Color of text is 2
shades darker than the default bead. Done only for Lee's abacus.
Motif: quick "o" or "$" does not change gui choice
Xt: pressing "o" twice causes "Warning: XtRemoveGrab asked to remove
a widget not on the list". Instead of XtDestroyWidget just
XtUnrealizeWidget shell. Add NULL check when creating shell.
Windows + Roman Numerals: problem with doing "calculate".
Windows + Anomaly/Watch: failing because of MAX_INT... needed to
change from 2^63-1 to 2^31-1.
"xmabacus hard to read": new bold fontlist in Abacus resource file
should address this.
Not that it mades sense, but 12ths added to broken bar example
caused not enough room for beads.
[Aug 31, 2012] V7.7.0:
Added mouse scroll. Also arrow keys with mouse work similarly now.
Abacus control left/right (or if vertical up/down) changes number of
rails.
[Jan 28, 2011] V7.6.8:
Had to reorganize letters to be in sync with Java version.
v Roman Nvmerals (was m)
m Museum (was e)
e Eighth (was h)
(h now used in attach/detach in Java html window)
Fixed a core dump when switching from eighths to twelfths.
[Sep 29, 2010] V7.6.7:
An old version got out in 7.6.6.
[Sep 27, 2010] V7.6.6:
Cbrt in teach now works, try like "3u" (cbrt of 3).
It flashes now when reached final answer in teach mode.
-decimalPosition now set auxiliary rails also.
[Sep 02, 2010] V7.6.5:
"2v" (sqrt of 2) in teach now works. Place decimal place appropriately
to give appropriate precision.
[Aug 03, 2010] V7.6.4:
Work around for
LessTif bug #2801540.
Problem is that LessTif will not automatically adjust its
displayed widgets to accommodate a new widget after the topLevel
is realized. So when choice of Teach/Demo/Base is chosen the
subwindow would have height of 1. Added a force to adjust the
frame in xabacus.c, if initial size of new window less than 2.
Works fine in Motif/OpenMotif. Did not use a check LESSTIF_VERSION
because it could be compiled on one and later used with different
library.
[Jul 06, 2010] V7.6.3:
Highlighting of beads added in teach mode.
[Jul 01, 2010] V7.6.2:
Highlighting of rail added in teach mode.
[Apr 14, 2010] V7.6.1:
Ran cppcheck which showed me I was using some non-portable sprintf's.
Now updated to use strcat.
[Jan 21, 2010] V7.6:
Version handling changed to a single version.h (and man page).
Sound fixed for esound.
[Nov 10, 2009] V7.5.5:
Windows version: fix to make demo, calc and teach dialogs consistent
Windows version: added accelerator for references.
teach division information: remove redundancy for single digit calc
more teach information for add/subtract
[Nov 02, 2009] V7.5.4:
Fractional fix for division.
Teach mode base fixes: division, multiplication, lee.
Teach mode: fixes for error handling.
[Oct 15, 2009] V7.5.3:
Teach mode: bug fixes and better error handling.
Lee's abacus: handle teach mode when formats are different.
Resynced C and Java code, man pages should closely relate to both
now.
Started on sqrt and cbrt but have trouble understanding the method
in "How to Learn Lee's Abacus" by Lee Kai-chen (which is using
Newton's method).
Started on colorizing "Teach" to make clear the current position
of calculation for digit and rail. Nothing to show for it yet,
but new "highlight" colors will be used for this.
[Oct 05, 2009] V7.5.2:
Division using teach should now work except for decimals.
Windows version has no auxiliary rails so this part just has to be
imagined. Values from current answer are just represented on
this rail so this is not a big leap.
[Jul 30, 2009] V7.5.1:
Found problem with borrow for subtraction and teach (e.g. 39-28).
Fixed demo to work more in sync with Java version.
Multiplication using teach should now should work.
Added lee options for controlling color and number of rails for
auxiliary decks from command line.
[Jun 05, 2009] V7.5:
Cleaned up menu look.
Fixed again for NAS sound.
Added "Teach" utility to allow teaching of addition and subtraction.
Tables are taken from "How to Learn Lee's Abacus" by Lee Kai-chen.
Generalized so bases should also work with "Teach".
Fixed bug in calculate when using quarters or quarter percents.
Changed name of flexible mode from "Other" to "Generic" and changed
default to be Chinese.
Moving beads when base was large for Russian or Danish format could
cause a false display of corruption error.
Put non-English names of Abacus in pull-down.
Added complement function, may be useful in future for negatives.
Added rightToLeft for "Teach". With it you can change from the
traditional left to right for addition and subtraction.
X and Windows - Older Releases
[Dec 14, 2008] V7.4.3:
Fixed for NAS sound.
[Jul 21, 2008] V7.4.1:
Strange character at end of help title removed.
Quit menu selection now works.
Fix for make install-png, thanks to solsTiCe d'Hiver .
[Jul 11, 2008] V7.4:
Leading function names in lowercase.
[Jun 01, 2008] V7.3.9: Not released
Made "t" and "b" names consistent with Java version ie, -tpiece now
-topPiece and -bpiece now -bottomPiece.
Japanese format 1,000,000,000,000,000,000,000,000.0+1 corruption fix.
Still does not add accurately as the math is using double.
Fixed various corruption and overflows.
[May 18, 2008] V7.3.8:
Fixed goof in ancientRoman.
[May 12, 2008] 7.3.7:
Allow latin for fractions when using Roman Numerals with -latin.
Allow signs on bars to be "modern" Roman Numerals with -modernRoman.
Allow older Roman Numerals to be displayed with -ancientRoman.
No group positions on abacus when anomaly is on.
[Apr 11, 2008] V7.3.6:
Allow "," for decimal point and "." for group separator. Probably,
should be done using locale but there are so many ways to configure
the abacus, I was not sure I should make an exception here and
configure it a different way.
Fixed bottom bead click which was 3 pixels off.
-pressOffset option added. Beads are now closer together.
Use option to access older way.
Beads are rounder with light bordering to distinguish beads easier.
Added color options for auxiliary beads.
[Apr 08, 2008] V7.3.5:
Eighths half added to menu and off by one error.
Eighths 1/2 bead was showing wrong value.
Calculation support when displayBase != base.
Commas should be ignored in calculations.
Implemented calculations for anomalies.
Calculation support up to base 20, which historically,
was the maximum base used. Babylonians used 60, but was a
conglomeration of base 10 and 6.
[Feb 29, 2008] V7.3.4:
Calculations like 4! can now be done in auxiliary fields.
Auxiliary text windows now proper sizes.
-script now defaults to stdout for X-Windows. Aux stuff now works
here also.
Changed pointer from crosshair to hand2.
gs has problems reading the distributed postscript file. In pixmaps
directory, I now distribute png files in case there are others like
me who have trouble reading it. As of now, these are not installed
automatically.
[Dec 24, 2007] V7.3.3:
Constants changed.
[Nov 27, 2007] V7.3.2:
Added -nolee option when compiled with -DABACUS_LEE.

Various small changes.
[Jul 26, 2007] V7.3.1:
Updated action codes and synchronized Java and C code.
Added eighths ability for Roman Hand Abacus, as suggested by Stephen
Stephenson. Setup for UK Museum version may not work as expected on
FR and IT versions.
Condense various menu defines to one set: "ACTION_*".
Windows fix for strange memory corruption when 'o' pressed for demo mode.
Windows now has black text for demo by default instead of green.
[Feb 23, 2007] V7.3:
HTML no longer corrupted.
mono and reverseVideo update.
Named fractions added for Roman numerals using 12ths and subdeck.
[Feb 20, 2007] V7.2.8:
Roman Hand Abacus fix for subdeck part 1/3 of 1/12 should really be
1/12 of 1/12 thanks to Ray Greaves .
[Feb 20, 2007] V7.2.7:
Setting up Roman Hand Abacus from .ad file caused core.
Fix for setting up twelfths and quarters from .ini file.
New bump.au sound, db lowered, and bumpdat.au removed, thanks to
http://audacity.sourceforge.net to help clean the sound up.
Setting decimal a little off for vertical.
[Dec 12, 2006] V7.2.6:
Option to format output to use commas so numbers can be read easier,
shortcut use "g" for group.
Fixed an overflow if number entered in display is too large.
Fixed menu to assure the OK part of queries is handled correctly.
Now use http://netpbm.sourceforge.net to generate images from xpm.
[Aug 08, 2006] V7.2.5:
Roman subdeck to Russian error fixed (ffftb.04f).
Roman subdeck error fixed (ffftb.04b).
Roman fix for pieces and piece percents.
Russian to Danish fix for twelfths.
Added more debugging.
[Jul 21, 2006] V7.2.4:
Fixed assorted memory leaks and uninitialized memory access reads.
[May 14, 2006] V7.2.3:
Tan frame.
Danish Elementary School abacus added (teaching aid).
Do not know how its used, setup as:
clears when pushed left
lowest order beads at bottom
kept simple so decimal point is at bottom
[Mar 06, 2006] V7.2.2:
Fixed bug for signs and quarter percents and subdecks.
Changed definition of CARRY buffer from 2 to 1, fixed display bug.
Anomaly now works when carries are possible. Although there is no
historical abacus like this, its nice to remove this requirement.
Pieces and piece percents now use "+" on bar except Roman Abacus.
Right click clear fix (off by one).
Made usage string compatible with versions of Motif and screen.
Fixed a problem for quarter percents where beads would get stuck.
Windows fix for printing of subdeck chars in Roman Abacus for Museum
of the Thermae in Rome.
[Feb 27, 2006] V7.2.1:
rngs.h left out of distribution, also some permission problems
on installation scripts.
Simplified code to switch to and from Russian abacus.
Redesigned rounded beads to always account for slots. I.e. a bead is
either an overlay of 2 circles and a rectangle if a wide bead or an
overlay of 4 circles and two rectangles (a cross) where there would
always be a flat edge along the width of a rail or slot.
[Jan 17, 2006] V7.2:
Added on 3 subdecks with 4 beads.
./xabacus -roman -rails 10 -tpiece 2 -bpiece 6 -subdeck 3 -subbead 4
1/2,1/4,1/3 ounces column now work for a Roman Abacus. This
comes in two flavors, where possibly the simpler one, needs 3 decks
(where a single bottom column would be) (one known example in
museum in British Museum in London). In the other flavor, the
beads could stop midway on a single slot (in IMHO not a well defined
way) (two known examples one in Museum of the Thermae in Rome and
one in Cabinet des medailles, Bibliotheque nationale, Paris).
Type "e" or use Museum option to cycle through museum pieces.
Added older Roman Signs "|x| (((|))) ((|)) (|) c x |" on bar.
Also allow these signs to be Roman Numerals.
If anomaly, calculations are not allowed.
Switching from/to Russian with a negative was broken.
Added more sanity checks for configuration, or it could go into a
weird state.
Fixed for small beads and PC version, would not have rounded slots.
Fixed top level room and spaces if top pieces or piecePercents
greater than 2.
[Jan 05, 2006] V7.1.8:
There were some cases where resizing the number of rails causes
the calculation to change unnecessarily.
Signed overflow fixes e.g. 50000000000*2=-5000 or
-100000000000 Chinese converted to Japanese.
Assorted tweaks discovered when porting code to Java version.
Moved Anomaly from "a" to "l" to be consistent with Java version.
Move bar problems with quarter percent.
Quarter percent for Russian format would give an X error, fixed.
[Jan 01, 2006] V7.1.7:
Sign, quarter, and quarterPercent code all rewritten to be less buggy.
Quarter percents option for 1/4 Kopecks.
Use of "piece" instead of "quarter" for more variability. This now
allows a "twelfths" capability (Roman ounces) for Roman Hand Abacus.
Its pretty configurable (with the configuration file) so you can have
a range from halves to sixteenths (stock market pricing, pieces of
eight, etc), and possibly beyond if you want to get crazy.
New symbols on the bar for "-" for sign, "O" for pieces. If the base and
piece and format in Russian style set weird it could otherwise be hard
hard to read. O used because it was used on the Roman Hand Abacus.
Anomaly option for Mesoamerican Nepohualtzintzin Abacus. Basically a
JP Abacus in base 20 (3/4) where the columns left of the 2nd digit are
multiples of 360 (instead of 400). 4th column of unit beads would be
20x360. Bar marked with an "X" where the anomaly is. Note: this
is turned off if there are extra beads as in the Chinese mode or
Korean mode or this leads to even more unexpected anomalies.
AnomalySq option to make more Anomaly more configurable, now can have a
representation of time using hours, minutes, seconds. Babylonians are
responsible for that mess. Though they probably did not use an
abacus.
[Nov 19, 2005] V7.1.6:
Vertical for proper Russian schoty (rotate xabacus clockwise 90 degrees).
Use "v" or from the command line -vertical.
The first bead that is 3 decimal places >= 1000 gets a darker color
on Russian Abacus.
[Oct 05, 2005] V7.1.5:
-version added
Common option help for X and X-Motif
[May 31, 2005] V7.1.4:
Separated out compatible components.
[Nov 21, 2004] V7.1.3:
Bug fixes for auto-calculation and small base values.
Thanks to Debian maintainer Florian Ernst for
esound fix.
[Oct 22, 2004] V7.1.2:
Small changes synchronizing with Java code.
Fixed goof introduced in previous which make quarter not work right.
[Sep 25, 2004] V7.1.1:
Installation of sound files.
bufferBead and colormap not properly initialized and could cause core
dumps.
[Aug 23, 2004] V7.1:
Thanks to Debian maintainer Florian Ernst for
pointing out that the demo breaks without Motif. Fixed this and 'f'
should now work better for X.
Beads are now double buffered. Faster and looks better on slow machines.
Beads now slide in small increments.
Got rid of turning the beads "inside-out" when pressed. Too annoying.
"<", ">" to speed up and slow down movement of the beads. Actually,
it changes "delay" inversely.
Got rid of some drawing errors when beads are long.
Sound added.
Sort of real time using gettimeofday.
[May 31, 2004] V7.0.6:
Demo now works with the other "standard" abaci. Korean (or Pre-WWII
Japanese) 1/5 (ko), Japanese 1/4 (or Roman) (jp), or Russian 0/10
(ru).
[Jan 23, 2004] V7.0.5: Not released
The idea with the calculator stuff is to see the beads
move with input from the display line. This will do a calculation
but it is not meant as a demonstration of a mathematical operation.
Do not use this for your taxes yet...
Has some special features... 2v = sqrt of 2, 2u = cbrt of 2, e for e,
p for pi, ! for factorial (should do a gamma function if real?), and
^ for power. Display Base must equal Abacus Base. Eventually want
to do operations on strings so abacus could be an "infinite" size.
Answers that result in an error default to zero (maybe all the beads
should fall off?).
[Jan 13, 2004] V7.0.4:
Clear for Lee's Abacus is for each individual deck except for demo.
Have the decimal point setting accessible to the demo.
I treat the decimal point as the place setting vernier...
Resources broken in 7.0.2 fixed.
Decrementing with the decimal on the right fixed.
Added the faster diamond shaped beads. :)
Color of decimal point the same as beads.
Put the decimal point (or place setting vernier) at a post. (To me it
should be between posts but have not seen an historic example).
Windows fixes: 'u' for quarters mode and rounder beads
[Dec 31, 2003] V7.0.3:
The Roman mode forces a plate look where the beads move in slots.
Fixed minor drawing errors in Windows.
Changed order of additions in the 4th lesson to conform with the
standard way of doing multiplication.
Fixed bug where a new 5th lesson not installed.
Fixed clean on auxiliary decks from demo.
Fixed demo mode on auxiliary decks.
[Dec 23, 2003] V7.0.2:
Lee's Abacus, default setup when using Motif. Added a 4th lesson
for multiplication. Find out more about Lee's Abacus from
http://www.ee.ryerson.ca/~elf/abacus/leeabacus/
Type of abacus listed for non-Motif and Windows.
Demo can now be set dynamically in Windows.
[Dec 15, 2003] V7.0.1:
Increment when decimal point left most bug fix.
The Hide functionality of the Escape key now iconifies or drops in
task bar.
Added help in Windows.
Accelerator Keys (F keys and regular keys) in Windows now work.
[Nov 08, 2003] V7.0:
Abacus??.ad* files removed, info is in Abacus.ad*.
Integrated winpuz6.5 (Windows 3.1/95) into X source tree.
[Aug 28, 2003] V5.7.3:
png for Gnome and KDE menus and xpm for CDE menus.
Added xpm for icon.
Reset a few colors for consistency.
[Aug 14, 2003] V5.7.2:
man 1 to man 6 and DESTDIR added and suggestions for ad.in stuff
thanks to Stanislav Brabec
The demo should work if the demo files are in the installation directory
(the default but can be changed by -demopath) or the current
directory.
Bug fix for xabacus -japanese -demo and a few involving "quarters".
User interface now free of numbers for formats.
[Aug 11, 2003] V5.7.1:
When changing base certain combinations would create too many beads
in top deck, beads are instead set to zero.
Reformatted with option menus.
Help kicked over.
Added Korean and Roman. Roman is essentially the same as the Japanese
version right now.
[Jul 07, 2003] V5.7:
Sync up with xpuzzles
[Apr 29, 2003] V5.6.2: Not released
Added callback for calculate... does not really do too much yet.
Need to #define CALC to try...
Bug fix when in Demo and Russian format is pressed
Clear now checks if you really want to clear using left mouse button,
'c' will not query
'Esc' will hide abacus (actually osfCancel did the trick)
Help & About expanded and pop-ups added
Took out bitmaps since it takes too much room
Demo can be activated from within window without needing command-line
-demo option. Removed leak in loadFont. Added 'o' functionality.
[Mar 21, 2003] V5.6.1:
Added runtime options -chinese, -japanese, and -russian
Fixed shading if beads are black
Installation fixes for Motif and X versions
Help & About expanded and pop-ups added
Roman Numerals added
Fixed uninstall on Cygwin
Took out toggles and bitmaps since it takes too much room.
Now compile-time option. There is real help and one can change
the toggles through the menu.
[Dec 16, 2002] V5.6:
configure if around 2nd AC_CHECK_FUNC
removed Sun CC (char *) warnings
removed hard coding of program name
Cygwin changes ./, -lSM -lICE
x and xm files combined using HAVE_MOTIF
port back from Java (on the Java side I got some help from
Sarat Chandran )
colors changes
frame color change on enter/leave
background/foreground set by default
3d beads
reset maximum
pixel width
"," diamonds
added signs and quarters (with smaller delay when moved)
Russian abacus (schoty) (it fell over)
[Sep 01, 2001] V5.5.4: g++ 3.0 warnings removed. Simplified format.
Added demo error checking.
[Aug 11, 1999] V5.5.2: Fixed runtime library problems when using configure,
added text to README and xabacus.man, fixed confusing demo start.
[Jul 31, 1999] V5.5.1: Removed HP usleep warning.
[Jun 20, 1999] V5.5: Combined the independent work of Luis Fernandes'
xabacus 1.00, also started in 1991. This includes all the features
to teach the users how to use the abacus (-demo) and a more solid
frame (its sturdier :) ). -bars changed to -rails to conform with
the terminology. Abacus now defaults to the top beads up. The
picture on the cover of my abacus instruction booklet was deceiving.
Abacus.ps and Abacus?.les are written entirely by Luis Fernandes
. (Also see http://www.ee.ryerson.ca/~elf/abacus).
Added -rv and -mono options.
Implemented -base option, can now go up to base 36, yeah I got carried
away here (it should even work with EBCDIC though untested (really
carried away)).
Dynamic number of rails, with calculations saved with each change.
[Jan 01, 1997] V5.4: configure, man page updates.
[Apr 22, 1996] V5.3: You can now see beads move one unit space at a time.
This is governed by a new resource, "delay".
[Feb 12, 1996] V5.2.1: beads now invert when pressed, wprintf name may
conflict with other UNIX libraries - changed to
motif_printf, keyboard may not work with motif - fixed.
[Jan 31, 1996] V5.2: Dynamic number of rails (well, the widget is dynamic
but xabacus.c limits it to around 300 for the title text),
fixed another bug when resized (negative radius circles).
[Dec 15, 1995] V5.1: Fixed a bug when resized.
[Sep 30, 1995] V5.0: Xt/Motif, your choice.
[May 16, 1995] V4.10: Warnings removed from Sun's cc and lint.
[Mar 13, 1995] V4.3: Removed lint warnings and added a VMS make.com .
[Nov 08, 1994] V4.2: Removed gcc -Wall warnings.
[Jun 03, 1994] V4.1: R6.
[May 07, 1994] V4.0: Xt version.
[Feb 03, 1993] V3.0: Motif version.
I got some good ideas from Douglas A. Young's book:
"The X Window System Programming and Applications with
Xt OSF/Motif Edition", particularly his dial widget.
I got some good ideas on presentation from Q. Zhao's
tetris.
[Dec 17, 1991] V2.0: XView version.
[Feb 14, 1991] V1.0: SunView version.
