DESCRIPTION:
|
|
------------
|
|
wmcalc is a program designed to act as a simple four-function
|
|
calculator. It is different from other calculator programs, however
|
|
in that it is designed to take up very little desktop space. As such,
|
|
it can be left running on the desktop at all times. It is intended to
|
|
placed in the WindowMaker dock, or in Wharf under Afterstep, though it
|
|
should run as well under any window manager.
|
|
|
|
LICENSING:
|
|
----------
|
|
This program is released under the GPL license. A copy (in case you
|
|
don't already have hundreds of them floating around) can be found in
|
|
this distribution in the file COPYING.

wmcalc. I'm listing them here as thanks for helping out, catching

bugs in the code, etc.

|
INSTALLATION:
|
|
-------------
|
|
Compile it:
|
|
make clean; make
|
|
|
|
As root, install it:
|
|
make install
|
|
|
|
Optionally, copy the config file:
|
|
cp wmcalc.conf ~/.wmcalc
|
|
|
|
Run it:
|
|
wmcalc &
|
|
|
|
Grab the appicon and move it to the dock.
|
|
Change the settings to start with Windowmaker
|
|
|
|
Afterstep Wharf 1.6.??: (I don't use Afterstep anymore, so...)
|
|
*Wharf wmcalc -Swallow "wmcalc" wmcalc &
|
|
|
|
***Note***:
|
|
The appicon only has a two pixel border where you can grab
|
|
and move it. It is easiest to grab along the bottom edge.
|
|
|
|
If make doesn't work, you may need to fiddle with the settings in
|
|
the Makefile.
|
|
|
|
Tested on: (Well, it runs, I don't know if 'Tested' is quite right...)
|
|
WindowMaker-0.62.1
|
|
X Clients: Red Hat 6.0, Kernel 2.2.8

|
|
-h Help. This message.
|
|
-f <filename> Full path to configuration file to use.

Buttons are defined as:
|
|
____________________
|
|
| x00 | where: x = 1 for Left Mouse Button
|
|
| 0 1 2 3 4 5 6 7 8 9| x = 2 for Middle Mouse Button
|
|
|--------------------| x = 3 for Right Mouse Button
|
|
|x01 x02 x03 x04 x05 |
|
|
|x06 x07 x08 x09 x10 | Note: the numbers 0..9 are the indicators
|
|
|x11 x12 x13 x14 x15 | for memory cells 0..9 respectively
|
|
|x16 x17 x18 x19 x20 |
|
|
--------------------
|
|
|
|
Button Functions:
|
|
100 Reinitialize the calculator, and both Registers
|
|
(Clear All)
|
|
200 Clear all the memory registers (0..10)
|
|
300 Clear the current number being entered only
|
|
x11 Start a program defined by CalcStart variable in config file
|
|
1yy Perform function shown on button
|
|
2yy Recall number from memory location [0-9] to display
|
|
for calculation
|
|
if yy = 2,3,4, 7,8,9, 12, 13, 14, 17
|
|
otherwise, can run a user-defined function (not implemented)
|
|
3yy Store Displayed number in memory location [0-9]
|
|
if yy = 2,3,4, 7,8,9, 12,13,14, 17
|
|
otherwise, can run a user-defined function (not implemented)
|
|
1xx Hopefully the other functions are obvious from their
|
|
button graphics.

NOTES:
|
|
------
|
|
I am sure that there are better ways to do some of the things that are
|
|
done in wmcalc. In fact, wmcalc is basically a series of hacks, but appears
|
|
to be stable...
|
|
|
|
The configuration file (.wmcalc) is written by wmcalc whenever the user
|
|
requests to store a number to memory. As a part of this process, a file
|
|
is written to /tmp. If /tmp is not accessible, it tries in the user's home
|
|
directory, as defined by the environment variable HOME. This file is
|
|
erased as soon as it is written over the main configuration file.
|
|
|
|
Changes made to the configuration file (other than memory stores) will not
|
|
take effect until the next time wmcalc is started.
|
|
|
|
Although one can only "Clear" all unlocked memory locations, one may clear the
|
|
display and then "store" a '0' in the memory location, providing the
|
|
ability to clear individual cells.
|
|
|
|
The fonts are stored in charmap.xpm. This file may be edited to
|
|
change colors or fonts, but the app must be recompiled for the changes
|
|
to take effect. The buttons are located in calcbuttons.xpm. This
|
|
file may be edited, though the borders should stay where they are
|
|
unless you want to change the button regions that are hard coded.
|
|
The background border is defined in backdrop.xpm.

"C code. C code run. Run, code, run.

PLEASE!?!?!?!?!?!?"

TODO:
|
|
-----
|
|
These are partially a dream list. I don't know when they'll get done,
|
|
as I'm pretty busy at work. Anyone want to tackle these??
|
|
|
|
* Re-implement the register/display design to allow full double precision.
|
|
|
|
* Add keyboard support (I've tried to do this, with no luck. Probably a
|
|
'focus' problem.
|
|
|
|
* Add button press animation.
|
|
|
|
* Add a log file, either as a paper tape implementation, or a file
|
|
that one can intentionally write data to. (This could grow to a pipe to
|
|
plotting programs, etc, though this is a bit extreme...)
|
|
|
|
RPN:
|
|
I have no intention at this time to add in an RPN format, as I
|
|
personally do not like it. It should be noted that I have NOT used it
|
|
extensively, and I've heard that I would like it. But, until then...
|
|
|
|
BUGS:
|
|
-----
|
|
Remember, they're just undocumented FEATURES!!!
|
|
|
|
* The display can lose the last digit of a three character exponential
|
|
notation number.
|
|
|
|
* Due to an implementation fault, at every step of calculations, precision
|
|
is lost, as the number is only as accurate at that displayed.
|
|
|
|
* Order of operations: 1 + 2 * 5 = 15, not 11, as it should.
|
|
|
|
* Changing sign when the display is blank results in "-0". Further entry
|
|
yields "-05...," but this does not affect calculations.
|
|
|
|
* Changes to the configuration file do not take effect until wmcalc is
|
|
restarted. (Note that file is written whenever a "store memory
|
|
location" is requested)
|
|
|
|
Probably many more. Send comments (preferably with fixes) to
|
|
<ehflora@access1.net>
|
|
I will happily include your name in the documentation for the program
|
|
if you send me a bug report and the correction. This can be in the
|
|
form of a patch file, or ASCII text to exchange, or an equivalent.
|
|
Note, this program is written in C. Not C++. I'm not a computer
|
|
science person, I don't do objects. Therefore, bug fixes that convert
|
|
this to C++ don't count, since I would no longer be able to support
|
|
the program. Of course, you can modify the code and release a new
|
|
application.
|
|
|
|
Thanks, and Good Luck.
