/*
* This is a slight modification of a JomeInput.java program
* The applet now accepts a few "parms" like:
*
* <param name="bgcolor" value="0xffff96">
* <param name="largefont" value="24">
* <param name="smallfont" value="16">
* <param name="wimsvars" value="x,y,z,n,d">
* <param name="oldreply" value="$wims_reply">
* <param name="my_panel" value="module_title:log[3]():sqrt[5]():and:or:isin:notin:R:Z:N:Q">
* <param name="helptext" value="f(x)=sin(3x)/cos(x^2)->f'(x)=">
*
* --> my_panel: a custom button panel ,tunable for the exercise at hand.
* --> wimsvars: a rudimentary form of "rawmath"...
* --> helptext: the exercise description ,some text may be allowed ?
*
*
* version 0.1
* 5/2007
* first rudimentary adaption for wims usage: filtering with javascript
*
* version 0.2
* 11/2007
* --> Introduction of log[g](a) and sqrt[g](a)
* --> Filtering now in poorly written java :)
* --> There still are some unresolved issues with "spaces" being turned into "+" signs by the included jome-code of applet.
* This is due to the fact that the applet -the way I use it- is not suitable for multiple-answers.(single line)
* --> The function "filter(String s1 , int k)" will change the "helptext" appletparam from ascii-math into "unicode" and reverse.
* Handling most common cases of false "+" signs.
* --> More reserved keywords can be included, if needed. [added div,times,notin,isin...etc etc]
* --> The helptext now gets stripped away in this applet, when the function getLinear() is called by javascript.
* (and will thus not be send as part of the answer)
*
*
* version 0.3
* 1/2008
* --> Deleted all useless references to MathML,OML...reducing size > 50% !
* --> Introduced <param name="oldreply" value="$wim_reply"> echoing the wims-rejected answer in the textareafield
* --> All (?) flaws of the applet are -hopefully- corrected...it should now be a one-line matheditor.
* In "Multi-aswers" statements/parts can be "glued" with arrows,and,or
* --> Domainsyntax allowed: [0:+inf> --> javascript --> lbracket 0 : +inf rangle
* --> Input sqrt[6](123) is also allowed...for "compatibility" with JS checkfiles
* --> Input log[8](123) is also allowed...for "compatibility" with JS checkfiles
* --> added reserved word array(1,2) used for a twoline "statement"
* --> multilines: array(first line , array(line two,line three)) etc etc
* --> restored the "," as special symbol -> n-th root : root(p,n) == sqrt[n](p)
* --> both n-th root syntaxes are read by javascript as: sqrt[n](p) --> send to wims as p^(1/n)
*
* version 0.4
* 3/2008
* --> compatible with java 1.4 ??? new replace function .... String.replace(String1,String2)
* --> vlist(line1,line2,line3....)

# Resources file for images in the expression :
# The syntax is the following :
#
# imageId = imageName:heightFactor:baseline:tInset:bInset:lInset:rInset
#
# imageId is the identificator of the desired image
#
# imageName is the name of the image, with an eventual subdirectory, which is relative to the package name
# of the image loader (all the images are located in subdectorie whose root is the package name of the imaghe loader)
# For example, if the image Image.gif is located in a subdirectory called subdir, this field has the subdir/Image.gif
# value.
#
# heightFactor is a factor to apply to the height of the original height of the image for rendering. The default height
# for an image is the height of the glyph of the current font. In some cases, for example specific symbols of operators,
# we want the symbol to be greater than the text elements of the expression (e.g. the sigma symbol for the sum is
# greater than the elements constituting it). This field determine how bigger is the symbol.
# If we want the image to be as high as the current font is, this field has 1.0 as value.
#
# baseline represents a virtual line to align the image with all the elements of the expression. It is expressed as a
# percentage of the height of the image, so its value have to be between 0.0 and 1.0.
# In some cases, we don't have to specify a particular baseline value (because as the height of the image is set by
# default to the height of the font, the baseline is the one of the font or because for it is calculating before
# rendering). Fore these cases, a null value should be set.
#
# tInset, bInset, lInset, rInset represent respectively a top, bottom, left and right insets to take
# into account around the image. This allows to have some space around the image inside the display
# which renders it.

# Resources file for images in the expression :
# The syntax is the following :
#
# imageId = imageName:heightFactor:baseline:tInset:bInset:lInset:rInset
#
# imageId is the identificator of the desired image
#
# imageName is the name of the image, with an eventual subdirectory, which is relative to the package name
# of the image loader (all the images are located in subdectorie whose root is the package name of the imaghe loader)
# For example, if the image Image.gif is located in a subdirectory called subdir, this field has the subdir/Image.gif
# value.
#
# heightFactor is a factor to apply to the height of the original height of the image for rendering. The default height
# for an image is the height of the glyph of the current font. In some cases, for example specific symbols of operators,
# we want the symbol to be greater than the text elements of the expression (e.g. the sigma symbol for the sum is
# greater than the elements constituting it). This field determine how bigger is the symbol.
# If we want the image to be as high as the current font is, this field has 1.0 as value.
#
# baseline represents a virtual line to align the image with all the elements of the expression. It is expressed as a
# percentage of the height of the image, so its value have to be between 0.0 and 1.0.
# In some cases, we don't have to specify a particular baseline value (because as the height of the image is set by
# default to the height of the font, the baseline is the one of the font or because for it is calculating before
# rendering). Fore these cases, a null value should be set.
#
# tInset, bInset, lInset, rInset represent respectively a top, bottom, left and right insets to take
# into account around the image. This allows to have some space around the image inside the display
# which renders it.

# className is the class to instanciate. The class name is fully qualified and then contains the name of the package

No memory, no buttons: a single input line.
Capable of sending the result -via javascript- to WIMS.

/**
The collection of names (<em>symbols</em>) used for parsing an expression
(the context in which the parsing takes place).<p>
Each symbol maps to either a {@link Function} or a constant.<p>
A symbol is identified by the pair (name, arity).
So a constant and a function with the same name,
or two function with the same name but with different arity
are distinct symbols.<p>
Symbols functions as a stack of <em>frames</em>:
when you pop the topmost frame, all the symbols added in that frame dissapear
(i.e. all the modifications done between the push and the pop are lost).<p>
Example:
<pre>
<code>
Symbols symbols = new Symbols();
symbols.eval("1+1"); //doesn't update symbols
symbols.define(symbols.compile("f(x)=x^2")); //updates symbols
</code>
</pre>
<p>
<h3>Thread safety</h3>
The Symbols class is thread-safe
(the same Symbols instance can be used by multiple threads without locking).<p>
The compile() methods are synchronized, so parallel compile() calls on the same Symbols
instance are serialized.

----- INFO ---------
Plinko and the Negative Binomial Distribution
A Bernoulli trial is an experiment that results in a success with probability p
and a failure with probability 1-p.
A random variable is said to have a Negative Binomial Distribution with
parameter r if it is the result of recording the number of successes before
the rth failure in repeated Bernoulli trials. The Geometric Distribution is
the special case of a Negative Binomial Distribution with r=1.
In the Applet below, we have represented repeated independent Bernoulli trials
by a single ball falling through an array of pins.
Each time a ball falls onto a pin, it will bounce to the right (i.e. a success)
with probability p or to the left (i.e. a failure) with probability 1-p.
After the ball falls through the array, it lands in a bin labeled by
the corresponding number of successes.
Click on a bin to see its corresponding total and probability.
Alternatively, use the left and right arrow buttons to scroll through the bins.
Also displayed is a confidence interval centered on the theoretical expected bin.
Bins that are included in this confidence interval are highlighted in green

----- asking approval by email
Dear Mr. D. Little,
In search of a suitable GALTON board applet for usage in Highschool mathteaching, I "stumbled" across Your very nice PLINKO applet.
My question is: am I allowed use Your applet for teaching ?
[e.g. incorporating it in "interactive math-teaching modules" of a WIMS server http://wims.math.leidenuniv.nl/wims/wims.cgi?lang=en ]
Kind regards,
J.M. Evers
Highschool Mathteacher
The Netherlands
----- reply by Dr. D. Little
Absolutely! I would be very happy for you to use the applet for teaching.
If you plan to include it on a webpage, I only ask that you include a
reference to me being the author (e.g., include a link back to my
webpage). Enjoy!
Best,
David
------ WIMS USAGE -------
2/2009 J.M. Evers:
To use the applet as part of an interactive WIMS exercise,
the source code had to be slightly modified.
see http://wims.math.leidenuniv.nl/wims/wims.cgi?lang=en&module=H4/stat/stat-1.nl&cmd=intro
Changes:
1) Introducing a few applet params to tailor the behaviour of the applet
by dynamic wims_variables and reading the generated data
from the applet with a javascript function.
These statistical data will be send to the wims-server for evaluation and
grading.
If the "wims_exercise" applet parameter is not set [ or "no" or "0" ] ,
the applet is identical to the original applet ! And all other params are "silently ignored".
2) Furthermore some text is translated to Dutch [nl] ,German [de] and French [fr] to be able
use the applet in multi-language exercises.
If no language param is set or not nl,de,fr : the language is English
3) And a "Close" button is added to the frame [to close the popup-window]
4) Bin numbering starts with "1" instead of "0" , if the applet <param name="wims_exercise" value="1">
5) All balls that fall to the right of the last bin will be collected/summed in the last item if the "applet reply"
a typical applet reply: 23,45,23,12,47
meaning:
bin 1: 23
bin 2: 45
bin 3: 23
bin 4: 12
rest : 47
----------- +
total balls = 150

* The SummationParser class makes it possible to use summations such as sum(i,1,5,x^i) in a Parser.

* summation, given as an expression; and (4) The expression that is summed. The values of

* encounters the name of a function in a string, it turns control
* of the parsing process over to the function. When a Function

* concrete subclasses of FunctionParserExtension represent actual
* functions. They must implement the five methods defined
* in the Function interface, but most of the parser- and expression-related
* behavior can probably be inherited from this class. (This is good, since
* the programming is rather tricky.)

/**
* A VariableSlider is a slider (implemented as a Scrollbar) whose
* position represents the value of an associated variable.
* The range of values represented by the slider is given by a pair of
* Value objects. They can be specified in the constructor or later with the
* setMin and setMax methods. A VariableSlider has an associated variable
* that represents the value of the slider. Note that the value of the variable
* can change only when the setInput() or checkInput() method is called.
* If you want the value of the variable to track the position
* of the slider as it is is manipulated by the user, add the slider to
* a Controller and set the Controller as the Slider's "onUserAction" property.
* This allows other objects that depend on the values of the slider to
* be recomputed by the controller when the value changes, as long as they
* are also registered with the Controller.
*
* <p>Some points to note:
*
* 1) setVal() can set a value outside the range from min to max,
* which will persist until the next time checkInput()
* or setVal() is called again.
* 2) If the value of min or max changes, the value of this variable
* will not change EXCEPT that it is clamped to the range between min and max.
* 3) Min does not have to be less than max.
* 4) The checkInput() routine only sets the needValueCheck flag to true.
* (The setVal() and getVal() routines both set this flag to false.) This "lazy evaluation" is used because
* checkInput() can't compute the new value itself. (The max and min
* might depend on Values that are themselves about to change when some
* other object's checkInput() mehtod is called.)
* 5) getVal() returns the current value, as stored in the variable,
* UNLESS needValueCheck is true. In that case, it recomputes
* the value first. getSerialNumber() works similarly.
* 6) A VariableSlider never throws JCMErrors. If an error occurs when min
* or max is evaluated, the value of the variable associated with this VariableSlider
* becomes undefined. (The point is, it doesn't generate any errors of its own.
* The error would be caused by other InputObjects which should throw
* their own errors when their checkInput() methods are called.)

/**
* A JCMPanel is a Panel with an associated Controller. When an InputObject or
* Computable is added to the JCMPanel, it is automatically added to the controller.
* When a sub-JCMPanel is added, the Controller of the sub-panel is "attatched" to
* the controller of the main panel so that objects in the sub-panel will also
* be controlled by the Controller of the main panel. So, if you build an
* interface entirely from JCMPanels, a lot of the control setup is done
* automatically. Note that to make this work, you will need
* a "mainPanel" that fills the entire window or applet (or at least the part that
* holds JCM components). You should also call the gatherInputs() method of
* the main JCMPanel after it is completely set up, so that changes in input objects
* will cause the panel's controller to be notified, or, alternatively, you
* can register the Controller by hand with InputObjects so that the
* Controller will be notified when they change.
*
* <p>The disadvantage of this is that all the data used in the interface is recomputed,
* even if the input objects that they depend on have not changed. For example.
* if the user changes the value in a VarialbleInput, all the points on a graph
* will be recomputed even if the function has not changed. The alternative is
* to use regular Panels for all or part of the interface and configure some
* Controllers by hand.

/**
* A DataTableInput lets the user input a grid of real numbers arranged
* in rows and columns. Each column has a name, and rows are numberd
* starting from 1. The column names and row numbers can be
* displayed, optionally. By default, a new row is added automatically
* if the user moves down out of the last row by pressing return
* or down-arrow, provided the last row is non-empty. Rows can also be
* added programmatically. Columns are usually added in the constructor,
* but they can also be added later. If the user leaves a cell
* at a time when the content of that cell does not represent a legal
* number, then the message "bad input" will be displayed in the cell.
* <p>A DataTableInput can be given a name and can then be added to a parser.
* The parser will then recognize the name of the table. In an expression, the table name
* can be followed by a ".", then one of the column names from table, then
* an expression in parentheses. This represents a reference to the number in
* one of the cells in the table. The expression gives the number of
* the row, where rows are numbered starting from 1. For example:
* "data.A(3)" represents the third number in column "A" in a table
* named data. The table name and "." can also be followed by the word "sum" and
* an expression in parentheses. An expression used in this way
* can include references to the column names in the table and to
* the special value "rowNumber". The value of expression is computed
* for each row in the table and the sum of the values is computed. In the expression that
* is being summed, a column name represents the
* number in that column and rowNumber represents the number of
* the row. For example: "data.sum(A^2)". Finally, the "." can be
* followed by the word "count". "count" can, optionally be followed
* by an empty pair of parentheses. This represents the number of
* rows. For example: "data.count". Empty rows at the bottom
* of the table are ignored in both "sum" and "count".
* <p>Note that rows are numbered starting from 1 because row numbers
* can be visible to the user, who shouldn't be subjected to zero-based
* numbering. However, columns are always numbered from zero.

* number value, which becomes the value of an associated Variable.
* The value of the Variable can change only when the VariableInput's
* checkInput() method is called (usually by a Controller). See the Controller
* class for more information.
*
* <p>Whenever checkInput is called, an error of type JCMError
* might be generated. If throwErrors is true, this error is
* thrown; if it is false, the error is caught, the value
* of the variable is set to Double.NaN, and no error is thrown.
* The error message associated with the error can be retrieved by
* calling getErrorMessage(), if desired. (This value is null if
* no error occurred the last time checkInput was called.)
*
* <p>A VariableInput is a Value, so it can be used directly where
* a Value object is needed.
*
* <p>An VariableInput will ordinarily be registered with
* a Controller in TWO ways: It's added to a Controller
* with the Controller's add() method. This makes the Controller
* call the VariableInput's checkInput() method during the
* Controller's compute() method. Secondly, a Controller
* is set as the "onUserAction" property. This causes the
* Controller's compute() method to be called when the user
* presses return in the VariableInput box. This is optional--
* you might, for example, only want the Controller to compute()
* when a Compute button is pressed. You can also set the
* VariableInput's onTextChange property to a Controller
* that you want to compute every time the text in the box
* changes.
*
* <p>After the VariableInput is created, it is possible to specify the
* largest and smallest allowed values for the variable. It is also
* possible to specify what sytle of input is allowed. The style
* can be to allow any constant expression, constant real numbers only,
* or integers only. Set these parameters with setMin(), setMax(),
* and setInputStyle(). For setInputStyle(), the legal parameter
* values are VariableInput.EXPRESSION, VariableInput.REAL, and

* An Animator can change a value continuously, without user intervention, by running
* a separate Thread. By default, an animator appears as a "Start" button. When the
* button is pressed, the value of the animator starts counting 0, 1, 2, ... The button
* changes to a "Stop" button. When this is pressed, the value stops changing. A Controller
* can be set, by calling the setOnChange() method, to be notified whenever the value is
* changed. If this is done, then the value of the Animator will only change when its
* checkInput() method is called, so it should be added to a Controller which will call
* this method.
*
* <p>The getValueAsVariable() method can be called to get a Variable whose value is
* the value of the Animator. This variable can then be added to a Parser, so it can
* be used in expressions. An Animator is "Tieable", so it can share its value
* with another InputObject, such as a VariableSlider or a VariableIput.
*
* <p>There are many options: If maximum and minimum values are both specified, then the value
* of the Animator ranges between these values. By default, this interval is divided into
* 100 sub-intervals, so that there are 101 frames. However, the number of intervals can
* also be set. If no min or max is specified but a number of intervals is specified,
* then the value is an integer which ranges from 0 up to the specified number of intervals.
* If the number of frames is finite, then there are three possibities when the last
* frame is reached: The animation can stop; it can loop back to the the starting
* frame, or it can reverse direction and cycle back and forth. The behavior is controlled
* with the setLoopStyle() method.
*

/**
* Controllers are the focus of all the action in the JCM system. A Controller can be
* set to listen for changes (generally changes in user input). This is done by
* registering the Controller with (usally) an InputObject. For example, if a Controller, c,
* is to respond when the user presses return in a VariableInput, v, then
* v.setOnUserAction(c) should be called to arrange to have the Controller listen
* for such actions. VariableSliders, ExpressionInputs, MouseTrackers, Animators have a similar
* methods. It is also possible to set the Controller to listen for events of
* type AdjustmentEvent, ActionEvent, TextEvent, or ItemEvent (but this feature is
* left over from an older version of JCM, and I'm not sure whether it's necessary).
* Whenever a Controller learns of some change, it will process any InputObjects,
* Ties, and Computables that have been registered with it.
*
* <p>InputObjects and Computables have to be added to a Controller to be processed,
* using the Controller's add method. (If you build your inteface out of JCMPanels,
* then this is done automatically.) (Note that an InputObject is added to a Controller
* to have its value checked -- This is separate from registering the Controller to
* listen for changes in the InputObject. Often, you have to do both.) The gatherInputs()
* method in class JCMPanel can be used to do most of this registration automaticaly.
*
* <p>A Tie that synchronizes two or more Values, to be effective, has to be added to a Controller.
* See the Tie class for inforamtion about what Ties are and how they are used.
*
* <p>A Controller can have an associated ErrorReporter, which is used to report any
* errors that occur during the processing. Currently, an ErrorReporter is either
* a DisplayCanvas or a MessagePopup.
*
* <p>A Controller can be added to another Controller, which then becomes a sub-controller.
* Whenever the main Controller hears some action, it also notifies all its sub-controllers
* about the action. Furthermore, it can report errors that occur in the sub-controllers,
* if they don't have their own error reporters. (Usually, you will just set an error
* reporter for the top-level Controller.)

/**
* A CoordinateRect represents a rectagular region in the xy-plane, specified
* by values xmin,xmax,ymin,ymax. The conditions ymin < ymax and xmin < xmax
* are enforced. (Values are swapped if necessary, and if min==max, they are
* reset to -1 and +1. If any of the values are set to an infinite or NaN
* value, then the coordinate rect won't display anything except the message
* "Error: undefined limits".)
* <P> When the Rect is mapped onto the screen, there can be a gap of a specified
* number of pixels between the min,max values and the edges of the rectangle
* on the screen. If the gap is non-zero, then the actual range of coordinates
* on the rect is larger than the range from the specifed min to max. (This is
* done mainly so I could have axes that don't quite reach the edges of the rect.)
* <P>A CoordinateRect maintains a list of Drawable items. When the Rect's
* draw() method is called, it calls the draw() method of each of the Drawable
* items it contains. When its compute() method is called, it calls the
* compute() method of any Drawable that is a Computable. When its checkInput()
* method is called, it calls the checkInput() method of any Drawable that is
* an InputObject.
* <P>A CoordinateRect represents a rectangular region in a DisplayCanvas.
* It has a reference to that Canvas, which is set automatically when it is
* added to the canvas. If the size, range, or gap on the CoordinateRect
* change, it will ask the Canvas to redraw the area it occupies.
*
* <P>The values of xmin, xmax, ymin, ymax are exported as Value objects,
* which can be used elsewhere in your program. The Value objects can
* be obtained by calling getValueObject(). If you do this, you should
* add the objects that depend on those values to a Controller and
* register the Controller to listen for changes from this CoordinateRect
* by calling the CoordinateRect.setOnChange(Controller) method.

/**
* A DrawString object displays a string, possibly multi-line, in a DisplayCanvas,
* inside the rectangular region of a CoordinateRect. The location of the string
* can be specified in two ways. First, by giving the coordinates of a reference
* point together with a constant that says how the string is positioned with
* respect to that reference point. The coordintes are given as Value objects
* and the values are interepreted in the coordinate system of the CoordinateRect.
* The positioning object is one of the constants TOP_LEFT, TOP_CENTER, ...,
* BOTTOM_RIGHT defined in this class. This says where the REFERENCE POINT
* is -- at the top left of the string, at the top center, etc.
* <p>The second way to specify the position of the string is to set the reference
* point coordinates to null. In that case, the postioning constant gives
* the location of the STRING in the CorrdinateRect. A value of TOP_LEFT
* says that the string is in the top left corner of the rect, etc.
*
* <p>An array of Value objects can be specified to be displayed in the string.
* Their values are substituted for #'s in the string. (A double # in the string,
* however, is displayed as a literal single #.)
*
* <p>It is possible to set the color, font and justification of the string.
*
* <p>A DisplayString implements the Computable interface, so it can be added to
* a Controller. The values of the Value objects used by the string are recomputed
* only when its compute() method is called.

* A DrawGeometric object is a geometic figure such as a line or rectangle that can
* be drawn in a CoordinateRect. The data for the object always consists of four
* numbers, which are interpreted differenetly depending on the object. These numbers
* can be specified as Value objects. A DrawGeometric is a Computable, and the
* Values will be re-computed when its compute() method is called. It should be
* added to a Controller that can respond to any changes in the data that define
* the Values. If one of the Value objects has an undefined value, nothing will be drawn.
* <p>The type of object is given as one of the constants defined in this class:
* LINE_ABSOLUTE, OVAL_RELATIVE, CROSS, and so on. In the descriptions of these
* constants, x1, x2, y1, and y2 refer to the values of Value objects that provide data
* for the DrawGeomentric while h and v refer to int's that can be specified in place of
* x2 and y2 for certain types of figures. For those figures, h or v is used if
* x2 or y2, respectively, is null.

/**
* A LimitControlPanel has four input boxes for specifying the xmin, xmax, ymin, and ymax
* of a CoodinateRect. You can actually add more than one CoordinteRect to the LimitControlPanel.
* This will synchronize the coordinate systems on the all the CoordinateRects that is controlls.
*
* <p>A LimitControlPanel can also contain a number of standard buttons, such as buttons for
* zooming the coordinates in and out. The buttons are specfied using constants
* defined in this class. It is possible to obtain standard buttons so that they can
* be displayed outside the LimitControlPanel. Furthermore, it is also possible to add other components
* to the panel, using the addRange(), addComponent(), and addComponentPair() methods.
* (The standard add() method from the Component class is overridded to call
* addComponent().) Any VariableInput added to the LimitControl Panel will appear with its name
* as a label, just above the input box.
*
* <p>Ordinarily, all the components are just stacked up vertically. However, if
* you set the useTwoColumnsIfPossible property to true, then they will be in two columns, unless
* the width of the Panel is too small for two columns. Pairs of items added
* with addRange() or addComponentPair() will appear on the same row. An item
* added with addComponent() will appear on a row by itself. As for the standard
* buttons, the following pairs will appear together, IF they are added at the
* same time: SET_LIMITS and EQUALUIZE; ZOOM_IN and ZOOM_OUT; SAVE and RESTORE.
*
* <p>A LimitControlPanel can have an error reporter, which is used to report
* any errors that are found in the input boxes for xmin, xmax, ymin, ymax
* (or other VariableInputs added with addRange()). Except for these
* input boxes, other coponents are NOT checked for errors.

* A DisplayCanvas is a drawing area that can contain one or more CoordinateRects.

* ignore the CoordinateRect and work only with the canvas.
* The option of using an offscreen image for double buffering is provided.
* By default, this option is on.
* <p>If a DisplayCanvas is added to a
* Controller, then it will take care of calling the checkInput()
* and compute() methods of the InputObjects and Computables that
* it contains, so there is no need to add them individually to
* the Controller. If the DisplayCanvas is added to a JCMPanel, it
* is automatically added to the Controller for that JCMPanel.
* (On the other hand, if a DisplayCanvas is added to a Controller,
* this means that all the
* items in the DisplayCanvas will be recomputed, even if only some
* of them need to be.)
* <p>The canvas can display an error message that goes away
* when the canvas is clicked or when clearErrorMessage()
* is called. This allows the Canvas to be used as an
* ErrorReporter for a Controller or LimitControlPanel.
* <p>When any changes are made to the contents of the Canvas,
* doRedraw() must be called for those changes to take effect.
* Normally, doRedraw() is called by the CoordinateRect or by
* one of the Drawables in a CoordinateRect. Use doRedraw(CoordinateRect c)
* or doRedraw(int index) to redraw a single CoordinateRect. Note that
* repainting the canvas is not enough, because this will not automatically

----- INFO ---------
Plinko and the Binomial Distribution
A Bernoulli trial is an experiment that results in a success
with probability p and a failure with probability 1-p.
A random variable is said to have a Binomial Distribution if
it is the result of recording the number of successes in n independent Bernoulli trials.
In the Applet below, we have represented repeated independent Bernoulli trials by a single ball
falling through an array of pins. Each time a ball falls onto a pin, it will bounce to the right
(i.e. a success) with probability p or to the left (i.e. a failure) with probability 1-p.
After the ball falls through the array, it lands in a bin labeled by the corresponding number of successes.
Click on a bin to see its corresponding total and probability.
Alternatively, use the left and right arrow buttons to scroll through the bins.
Also displayed is a confidence interval centered on the theoretical expected bin.
Bins that are included in this confidence interval are highlighted in green.
* The name Plinko refers to a game played on The Price Is Right.
However, the game show version is played on a rectangular array of pins instead of a triangular array.
It would be more appropriate to call our applet Galton's board or a quincunx board,
however this is far more difficult to pronounce.

------ WIMS USAGE -------
11/2010 J.M. Evers:
Corrected param flaw (speed could not be changed from default speed=1 )
7/2008 J.M. Evers:
To use the applet as part of an interactive WIMS exercise,
the source code had to be slightly modified.
see http://wims.math.leidenuniv.nl/wims/wims.cgi?lang=en&module=H4/stat/stat-1.nl&cmd=intro
Changes:
1) Introducing a few applet params to tailor the behaviour of the applet
by dynamic wims_variables and reading the generated data
from the applet with a javascript function.
These statistical data will be send to the wims-server for evaluation and
grading.
If the "wims_exercise" applet parameter is not set [ or "no" or "0" ] ,
the applet is identical to the original applet.
And all other params are "silently ignored".
2) Furthermore some text is translated to Dutch [nl] ,German [de] and French [fr] to be able
use the applet in multi-language exercises.
If no language param is set or not nl,de,fr : the language is English
3) And a "Close" button is added to the frame [to close the popup-window]
4) Bin numbering starts with "1" instead of "0" , if the applet <param name="wims_exercise" value="1">

Chemistry input applet for WIMS
Slightly based on ideas [and bits of code from...] http://web.uconn.edu/~cdavid
+ -
A chemical formula input like : H O + OH -> 2H O
3 2
And it's all amateur scriblings, no copyrights
Note: if the jar is not "signed" there will an annoying grey "bar" be visible with the text
"Java Applet Window". [in appletviewer this grey bar will probably be visible, anyway]
TODO: help & usage in onmouseover?
Example:

Chemistry input applet for WIMS
Slightly based on ideas [and bits of code from...] http://web.uconn.edu/~cdavid
+ -
A chemical formula input like : H O + OH -> 2H O
3 2
And it's all amateur scriblings, no copyrights
Note: if the jar is not "signed" there will an annoying grey "bar" be visible with the text
"Java Applet Window". [in appletviewer this grey bar will probably be visible, anyway]
TODO: help & usage in onmouseover?
Example:

This is all amateur scriblings...so No Copyrights
the applet presents a simple grid...E6/H1 pupils will be asked to
determine the perimetre and surface area (or ratio of these) of a "freestyle" figure
build from at least $x squares...
In the non-interactive mode, a random figure will be shown.
size_x and size_y may be different: the perimetre will be a float : calulated with x=1 y=size_y/size_x
example html page:
<html>
<body>
<script language="javascript" type="text/javascript">
function lees(){
var input=document.applets[0].ReadApplet();
alert(input);
<--- applet returns: String S=total+","+original+","+changed+","+cnt;
!! total squares,left original squares,changed squares,perimetre of changed squares
-->

color1="background"
color2="clicked" in "interactive"=1
color2="questioncolor" in "interactive"=0
color may also be "red","green","blue","orange","yellow"
21/3/2008 added:
level: integer 0,1,2,3 only interesting when "interactive=0" (and not of importance for "percentage")
level=0 will produce somewhat easier random figures: level=3 will give maximum randomness.
percentage: only activated when "interactive=0" . Will give a random figure : but a non-random placement of the coloured squares.
thus an very easy reading of a "percentage coloured" surface. Use together with max_x and max_y to build easy exercises.
percentage=1 and level>0 will produce alternating coloures
percentage=1 and level=0 will produce a coloured block
22/3/2008 added
color names : lightgreen,lightblue,brown,pink,cyan,salmon
for both params level/percentage a full coloured figure is inhibited (so never 0% coloured or 100% coloured)

Change logs
===================================
1.2
- Column headers enabled
- Column width can be dynamically adjusted
1.1
- Rewrote base dialog class (SharpDialog) and all other dialog subclasses;
this makes creating new dialogs much easier
- Shariz Kanga <skanga@bigfoot.com> made Sharp Tools able to import tables
from a database by JDBC. Tested with HSQL and Oracle (by Shariz) and
MySQL (by me).
- Use extention file name ".cvs" instead of ".sts".
- Put stuff in jar files.
If you want to use the new database function, you need to download the JDBC
driver(s) and put in CLASSPATH (edit SharpTools or SharpTools.bat).
Below are some such websites:
MySQL: http://www.worldserver.com/mm.mysql/
HSQL: http://sourceforge.net/projects/hsqldb/

Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Sharp Tools Spreadsheet version 1.2
===================================
Copyright (C) 2000-2001, Hua Zhong <huaz@cs.columbia.edu>
Copyright (C) 2000, Sharp Tools Team <sharp@cs.columbia.edu>
Sharp Tools spreadsheet was originally a Software Engineering course project
finished in the fall of 2000 by five CS students at Columbia University. It
is not a commecial product, nor is it meant to replace StarOffice, but it has
all the basic functionality as a spreadsheet. We also hope people can learn
from the code.
This is a development version. The documentation may be inaccurate.
===================================
Web sites
===================================
The official web site is http://www.cs.columbia.edu/sharptools/.
It's also available at:
SourceForge: http://sharptools.sourceforge.net/
Freshmeat: http://freshmeat.net/projects/sharptools/
===================================
Build and Run
===================================
If you want to build/run your own code, do the following (assuming Unix):
$ cd src
$ make
$ jar cvf SharpTools.jar *.class
$ mv SharpTools.jar ../bin
$ cd ../bin
$ ./SharpTools
You have to do so if you check out the code from CVS.
===================================
Database
===================================
If you want to use the new database function, you need to download the JDBC
driver(s) and put in CLASSPATH (edit SharpTools or SharpTools.bat).
Below are some such websites:

*********************************************************************************
* J.M. Evers 19/11/2009*
* This is all amateur scriblings... So no copyrights.*
* This source code file, and compiled classes derived from it,*
* can be used and distributed without restriction, including for commercial use*
* No warrenty whatoever*
*********************************************************************************
I've used some code from X.Gang's input applet , to make it "compatibel"
with existing usage...although not thoroughly tested :(
And Gang's applet was an extended version of the original draw.java distributed with java applets as demo.
This work was GNU
And the Javia-libs however are excellent java and are GNU.
1) Syntax ; similar (...) to flydraw
[filled || dashed]
object coordinate_data,color [optional ,alpha,linewidth]
2) Compatibility with Input.java ex Gang
Use the normal applet params for Input.java [e.g without the script]
Or abandon the input_applet_params and let the script to produce the background image:
userdraw points | line | lines | (f)polygon | vector | (f)circle | (f)rect | semiline | points | curve
controls yes/no [use the direct reply buttons]
pointstyle cross | dot : only for userdrawing
new: right mousebutton removes parts of drawing
The result can be read through usual direct contact with wims.cgi
or via Javascript using ReadApplet() :
in this case the answers will be in the coordinate system of the drawing
[xrange/yrange] and always a list x1,y1,x2,y2,x3,y3.....
3) Using the applet as an drawable image [mouse drawinteraction] + coordinates display
mouse yes
userdraw points | line | lines | (f)polygon | (f)rect | vector | (f)circle | semiline | points | curve
coordinates yes/no or left out
pointstyle cross | dot
Drawing can be read via Javascript using ReadApplet() :
The answers will be in the coordinate system of the drawing
[xrange/yrange] and always a list x1,y1,x2,y2,x3,y3.....
4) Using the applet as an non_user_drawable image with coordinates display
mouse no
coordinates yes
5) Using the applet as a normal Fly image
mouse no
coordinates no
[this is default]
6) Script syntax [a sort of fly-script]
xrange int,int
yrange int,int
linewidth int
transparent color [,alpha]
dline || line x1,y1,x2,y2,color [,alpha,linewidth]
dhline || hline x1,x1,color [,alpha,linewidth]
dvline || vline x1,x1,color [,alpha,linewidth]
darrow || arrow x1,y1,x2,y2,head_factor(0.0001 - 0.99999),color [,alpha,linewidth
dpoly || poly || fpoly x1,y1...x_n,y_n,color [,alpha,linewidth]
drect || rect || frect x1,y1,x2,y2,color [,alpha,linewidth]
dtriangle || triangle || ftrianlge x1,y1,x2,y2,x3,y3,color [,alpha,linewidth]
points x1,y1,x2,y2...x_n,y_n,color [,alpha,linewidth]
point x,y,color [,alpha,linewidth]
pointstyle cross | dot : only for userdrawing
dcircle || circle || fcircle xc,yc,r,color [,alpha,linewidth]
dellipse || ellipse || fellipse xc,yc,r1,r2,color [,alpha,linewidth]
farc || arc xc,yc,radius,start_angle,end_angle,color [,alpha]
dgrid || grid xmajor,ymajor,xminor,yminor,color_mayor,color_minor,linewidth,linewidth [,alpha_major,alpha_minor]
example: grid 1,1,0.5,0.5,red,blue,2,1,190,120
parallel x1,y1,x2,y2,dx,dy,n,color [,alpha,linewidth]
plotsteps [int] default ysize
dcurve || curve || function in x,color [,alpha,linewidth]
image x1,y1,url // x & y are in coordinate system xrange/yrange
text x,y,fontname,fontsize,the_text_without_comma,color [,alpha] few latexstrings allowed rightarrow alpha beta Beta
textup x,y,angle,fontname,fontsize,some_the_text_without_comma,color [,alpha] : angle = clockwise rotation in degrees
precision 100 // 2 decimals for reading coords with "mouse yes"
debug yes //some info on loading script and other trouble
todo:
- Animating curves [very hard?]
- Animated gif as background
- xlogscale / ylogscale
wishlist:
- standalone application with menubars ; export drawing as flyscript ?
- using frame ?

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

The collection of names (<em>symbols</em>) used for parsing an expression

So a constant and a function with the same name,

Symbols functions as a stack of <em>frames</em>:
when you pop the topmost frame, all the symbols added in that frame dissapear

symbols.define(symbols.compile("f(x)=x^2")); //updates symbols

/trunk/wims/src/Misc/authors/jm.evers/applets/TexApp/CHANGELOG
0,0 → 1,19
20/12/2010
- Ant build.
15/5/2010
- This is an "inline latex" viewer with input/reply option.
- Using the ATP library for fast latex_image generation for a "usable" amount of latex syntax.
- Added applet_auto_scaling.
- Added euro symbol \euro
- For applet autoscaling, the applet_tag "width" should be less than 10 : width="1"
- The autoscaling SetSize() javascript_function from the test.html adresses
the applets public function "getPrefferedSize();".
It could/should be called from the htmlpage "body onload".
Or in WIMS:
!set wims_html_onload=javascript:SetSize('TexApp');
If the applet has a width > 10 , no autoscaling is performed.
- The number of inputfields can be "user_controlled": see test.html
The fontsize is adapted to the inputfield height [more or less].

For applet autoscaling, the applet_tag "width" should be less than 10 : width="1"<br>
The autoscaling SetSize() javascript_function could be called from the htmlpage "body onload".<br>
Or in WIMS:<br>
!set wims_html_onload=javascript:SetSize('TexApp');
<br>
If the applet has a width &gt; 10 , no autoscaling is performed.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

For applet autoscaling, the applet_tag "width" should be less than 10 : width="1"<br>
The autoscaling SetSize() javascript_function could be called from the htmlpage "body onload".<br>
Or in WIMS:<br>
!set wims_html_onload=javascript:SetSize('TexApp');
<br>
If the applet has a width &gt; 10 , no autoscaling is performed.

version 0.4
10/12/2010
Added param pointsize to differ size of points from linewidth
Removed −&times from html reply (problems with representation after sending to wims)
now just ascii + - : x
version 0.3
Added decimals [point object]
version 0.2
Added correct French button text [B. Perrin-Riou]
Added left hand +,-,x,: sign next to the lines [when language=fr ]
version 0.1
Applet for simple adding, subtracting,dividing and multiplying by pupils.
The result can be checked by WIMS.
Output:
document.getElementById('InvulGrid').ReadApplet("0") : itemlist [one item per horizontal line]
document.getElementById('InvulGrid').ReadApplet("1") : javascript confirmbox
document.getElementById('InvulGrid').ReadApplet("2") : html table
document.getElementById('InvulGrid').ReadApplet("3") : latex array/table
Example [same as test.html]
<html>
<body>
<script type="text/javascript">
function ReadThis(){
var wims_reply = document.getElementById('InvulGrid').ReadApplet("0");
alert("this can send to wims for correction:\n"+wims_reply);

/**
The collection of names (<em>symbols</em>) used for parsing an expression
(the context in which the parsing takes place).<p>
Each symbol maps to either a {@link Function} or a constant.<p>
A symbol is identified by the pair (name, arity).
So a constant and a function with the same name,
or two function with the same name but with different arity
are distinct symbols.<p>
Symbols functions as a stack of <em>frames</em>:
when you pop the topmost frame, all the symbols added in that frame dissapear
(i.e. all the modifications done between the push and the pop are lost).<p>
Example:
<pre>
<code>
Symbols symbols = new Symbols();
symbols.eval("1+1"); //doesn't update symbols
symbols.define(symbols.compile("f(x)=x^2")); //updates symbols
</code>
</pre>
<p>
<h3>Thread safety</h3>
The Symbols class is thread-safe
(the same Symbols instance can be used by multiple threads without locking).<p>
The compile() methods are synchronized, so parallel compile() calls on the same Symbols
instance are serialized.

URL, use the read() method<br>
<p>
When calling the public methods, in most cases the changes will not
be visible until paint() has been called<br> To request that this
be done, call repaint()<br> One exception is addPoint(), which
makes the affect of the new point visible immediately (or nearly
immediately) if the plot is visible on the screen<br>
<p>
The ASCII format for the file file contains any number commands,
one per line<br> Unrecognized commands and commands with syntax
errors are ignored<br> Comments are denoted by a line starting with a
pound sign "#"<br> The recognized commands include those supported by
the base class, plus a few more<br> The commands are case
insensitive, but are usually capitalized<br> The number of data sets
to be plotted does not need to be specified<br> Data sets are added as needed<br>
Each dataset is identified with a color (see the base class)<br>
<P>
The appearance of the histogram can be altered by the following commands:
<pre>
Bars: <i>width</i>
Bars: <i>width, offset</i>
</pre>
The <i>width</i> is a real number specifying the width of the bars
as a fraction of the bin width<br> It usually has a value less than
or equal to one,
and defaults to 0<br>5<br> The <i>offset</i> is a real number
specifying how much the bar of the <i>i </i><sup>th</sup> data set
is offset from the previous one<br> This allows bars to "peek out"
from behind the ones in front<br> It defaults to 0<br>15<br>
Note that the frontmost data set will be the first one<br>
<p>
The width of each bin of the histogram can be specified using:
<pre>
BinWidth: <i>width</i>
</pre>
This is given in whatever units the data has<br>
By default, each bin is centered at <i>x</i> = <i>nw</i>,
where <i>w</i> is the width of the bin and <i>n</i> is an integer<br>
That bin represents values in the range (<i>x - w/2, x + w/2</i>)<br>
The alignment of the bins can be changed with the following command:
<pre>
BinOffset: <i>offset</i>
</pre>
If this method is used with argument <i>o</i>, then each bin is
centered at <i>x = nw + o</i>, and represents values in the range
(<i>x - w/2 + o, x + w/2 + o</i>)<br> So for example, if <i>o = w/2</i>,
then each bin represents values from <i>nw</i> to
(<i>n</i> + 1)<i>w</i> for some integer <i>n</i><br>
The default offset is 0<br>5, half the default bin width<br>
<p>
To specify data to be plotted, start a data set with the following command:
<pre>
DataSet: <i>string</i>
</pre>
Here, <i>string</i> is a label that will appear in the legend<br>
It is not necessary to enclose the string in quotation marks<br>
To start a new dataset without giving it a name, use:
<pre>
DataSet:
</pre>
In this case, no item will appear in the legend<br>
New datasets are plotted <i>behind</i> the previous ones<br>
The data itself is given by a sequence of numbers, one per line<br>
The numbers are specified as
strings that can be parsed by the Double parser in Java<br>
It is also possible to specify the numbers using all the formats
accepted by the Plot class, so that the same data may be plotted by
both classes<br> The <i>x</i> data is ignored, and only the <i>y</i>
data is used to calculate the histogram<br>

<p>
A histogram plotter<br> The plot can be configured and data can
be provided either through a file with commands or through direct
invocation of the public methods of the class<br> To read a file or a
URL, use the read() method<br>
<p>
When calling the public methods, in most cases the changes will not
be visible until paint() has been called<br> To request that this
be done, call repaint()<br> One exception is addPoint(), which
makes the affect of the new point visible immediately (or nearly
immediately) if the plot is visible on the screen<br>
<p>
The ASCII format for the file file contains any number commands,
one per line<br> Unrecognized commands and commands with syntax
errors are ignored<br> Comments are denoted by a line starting with a
pound sign "#"<br> The recognized commands include those supported by
the base class, plus a few more<br> The commands are case
insensitive, but are usually capitalized<br> The number of data sets
to be plotted does not need to be specified<br> Data sets are added as needed<br>
Each dataset is identified with a color (see the base class)<br>
<P>
The appearance of the histogram can be altered by the following commands:
<pre>
Bars: <i>width</i>
Bars: <i>width, offset</i>
</pre>
The <i>width</i> is a real number specifying the width of the bars
as a fraction of the bin width<br> It usually has a value less than
or equal to one,
and defaults to 0<br>5<br> The <i>offset</i> is a real number
specifying how much the bar of the <i>i </i><sup>th</sup> data set
is offset from the previous one<br> This allows bars to "peek out"
from behind the ones in front<br> It defaults to 0<br>15<br>
Note that the frontmost data set will be the first one<br>
<p>
The width of each bin of the histogram can be specified using:
<pre>
BinWidth: <i>width</i>
</pre>
This is given in whatever units the data has<br>
By default, each bin is centered at <i>x</i> = <i>nw</i>,
where <i>w</i> is the width of the bin and <i>n</i> is an integer<br>
That bin represents values in the range (<i>x - w/2, x + w/2</i>)<br>
The alignment of the bins can be changed with the following command:
<pre>
BinOffset: <i>offset</i>
</pre>
If this method is used with argument <i>o</i>, then each bin is
centered at <i>x = nw + o</i>, and represents values in the range
(<i>x - w/2 + o, x + w/2 + o</i>)<br> So for example, if <i>o = w/2</i>,
then each bin represents values from <i>nw</i> to
(<i>n</i> + 1)<i>w</i> for some integer <i>n</i><br>
The default offset is 0<br>5, half the default bin width<br>
<p>
To specify data to be plotted, start a data set with the following command:
<pre>
DataSet: <i>string</i>
</pre>
Here, <i>string</i> is a label that will appear in the legend<br>
It is not necessary to enclose the string in quotation marks<br>
To start a new dataset without giving it a name, use:
<pre>
DataSet:
</pre>
In this case, no item will appear in the legend<br>
New datasets are plotted <i>behind</i> the previous ones<br>
The data itself is given by a sequence of numbers, one per line<br>
The numbers are specified as
strings that can be parsed by the Double parser in Java<br>
It is also possible to specify the numbers using all the formats
accepted by the Plot class, so that the same data may be plotted by
both classes<br> The <i>x</i> data is ignored, and only the <i>y</i>
data is used to calculate the histogram<br>

Data processed via param "dataurl" (datafile)<p>
Using the "ptolemy.plot.HistogramApplet" from the Plot.jar
<p>
<applet width = "640" height = "480" codebase=".." archive="Plot.jar" code="ptolemy.plot.HistogramApplet">
<param name = "progressbar" value = "true">
<param name = "scriptable" value = "false">

<param name = "file" value="http://localhost/data.txt">
</applet>
<p>
A histogram plotter<br> The plot can be configured and data can
be provided either through a file with commands or through direct
invocation of the public methods of the class<br> To read a file or a
URL, use the read() method<br>
<p>
When calling the public methods, in most cases the changes will not
be visible until paint() has been called<br> To request that this
be done, call repaint()<br> One exception is addPoint(), which
makes the affect of the new point visible immediately (or nearly
immediately) if the plot is visible on the screen<br>
<p>
The ASCII format for the file file contains any number commands,
one per line<br> Unrecognized commands and commands with syntax
errors are ignored<br> Comments are denoted by a line starting with a
pound sign "#"<br> The recognized commands include those supported by
the base class, plus a few more<br> The commands are case
insensitive, but are usually capitalized<br> The number of data sets
to be plotted does not need to be specified<br> Data sets are added as needed<br>
Each dataset is identified with a color (see the base class)<br>
<P>
The appearance of the histogram can be altered by the following commands:
<pre>
Bars: <i>width</i>
Bars: <i>width, offset</i>
</pre>
The <i>width</i> is a real number specifying the width of the bars
as a fraction of the bin width<br> It usually has a value less than
or equal to one,
and defaults to 0<br>5<br> The <i>offset</i> is a real number
specifying how much the bar of the <i>i </i><sup>th</sup> data set
is offset from the previous one<br> This allows bars to "peek out"
from behind the ones in front<br> It defaults to 0<br>15<br>
Note that the frontmost data set will be the first one<br>
<p>
The width of each bin of the histogram can be specified using:
<pre>
BinWidth: <i>width</i>
</pre>
This is given in whatever units the data has<br>
By default, each bin is centered at <i>x</i> = <i>nw</i>,
where <i>w</i> is the width of the bin and <i>n</i> is an integer<br>
That bin represents values in the range (<i>x - w/2, x + w/2</i>)<br>
The alignment of the bins can be changed with the following command:
<pre>
BinOffset: <i>offset</i>
</pre>
If this method is used with argument <i>o</i>, then each bin is
centered at <i>x = nw + o</i>, and represents values in the range
(<i>x - w/2 + o, x + w/2 + o</i>)<br> So for example, if <i>o = w/2</i>,
then each bin represents values from <i>nw</i> to
(<i>n</i> + 1)<i>w</i> for some integer <i>n</i><br>
The default offset is 0<br>5, half the default bin width<br>
<p>
To specify data to be plotted, start a data set with the following command:
<pre>
DataSet: <i>string</i>
</pre>
Here, <i>string</i> is a label that will appear in the legend<br>
It is not necessary to enclose the string in quotation marks<br>
To start a new dataset without giving it a name, use:
<pre>
DataSet:
</pre>
In this case, no item will appear in the legend<br>
New datasets are plotted <i>behind</i> the previous ones<br>
The data itself is given by a sequence of numbers, one per line<br>
The numbers are specified as
strings that can be parsed by the Double parser in Java<br>
It is also possible to specify the numbers using all the formats
accepted by the Plot class, so that the same data may be plotted by
both classes<br> The <i>x</i> data is ignored, and only the <i>y</i>
data is used to calculate the histogram<br>

<p>
A histogram plotter<br> The plot can be configured and data can
be provided either through a file with commands or through direct
invocation of the public methods of the class<br> To read a file or a
URL, use the read() method<br>
<p>
When calling the public methods, in most cases the changes will not
be visible until paint() has been called<br> To request that this
be done, call repaint()<br> One exception is addPoint(), which
makes the affect of the new point visible immediately (or nearly
immediately) if the plot is visible on the screen<br>
<p>
The ASCII format for the file file contains any number commands,
one per line<br> Unrecognized commands and commands with syntax
errors are ignored<br> Comments are denoted by a line starting with a
pound sign "#"<br> The recognized commands include those supported by
the base class, plus a few more<br> The commands are case
insensitive, but are usually capitalized<br> The number of data sets
to be plotted does not need to be specified<br> Data sets are added as needed<br>
Each dataset is identified with a color (see the base class)<br>
<P>
The appearance of the histogram can be altered by the following commands:
<pre>
Bars: <i>width</i>
Bars: <i>width, offset</i>
</pre>
The <i>width</i> is a real number specifying the width of the bars
as a fraction of the bin width<br> It usually has a value less than
or equal to one,
and defaults to 0<br>5<br> The <i>offset</i> is a real number
specifying how much the bar of the <i>i </i><sup>th</sup> data set
is offset from the previous one<br> This allows bars to "peek out"
from behind the ones in front<br> It defaults to 0<br>15<br>
Note that the frontmost data set will be the first one<br>
<p>
The width of each bin of the histogram can be specified using:
<pre>
BinWidth: <i>width</i>
</pre>
This is given in whatever units the data has<br>
By default, each bin is centered at <i>x</i> = <i>nw</i>,
where <i>w</i> is the width of the bin and <i>n</i> is an integer<br>
That bin represents values in the range (<i>x - w/2, x + w/2</i>)<br>
The alignment of the bins can be changed with the following command:
<pre>
BinOffset: <i>offset</i>
</pre>
If this method is used with argument <i>o</i>, then each bin is
centered at <i>x = nw + o</i>, and represents values in the range
(<i>x - w/2 + o, x + w/2 + o</i>)<br> So for example, if <i>o = w/2</i>,
then each bin represents values from <i>nw</i> to
(<i>n</i> + 1)<i>w</i> for some integer <i>n</i><br>
The default offset is 0<br>5, half the default bin width<br>
<p>
To specify data to be plotted, start a data set with the following command:
<pre>
DataSet: <i>string</i>
</pre>
Here, <i>string</i> is a label that will appear in the legend<br>
It is not necessary to enclose the string in quotation marks<br>
To start a new dataset without giving it a name, use:
<pre>
DataSet:
</pre>
In this case, no item will appear in the legend<br>
New datasets are plotted <i>behind</i> the previous ones<br>
The data itself is given by a sequence of numbers, one per line<br>
The numbers are specified as
strings that can be parsed by the Double parser in Java<br>
It is also possible to specify the numbers using all the formats
accepted by the Plot class, so that the same data may be plotted by
both classes<br> The <i>x</i> data is ignored, and only the <i>y</i>
data is used to calculate the histogram<br>

//// Histogram
/**
A histogram plotter. The plot can be configured and data can
be provided either through a file with commands or through direct
invocation of the public methods of the class. To read a file or a
URL, use the read() method.
<p>
When calling the public methods, in most cases the changes will not
be visible until paint() has been called. To request that this
be done, call repaint(). One exception is addPoint(), which
makes the affect of the new point visible immediately (or nearly
immediately) if the plot is visible on the screen.
<p>
The ASCII format for the file file contains any number commands,
one per line. Unrecognized commands and commands with syntax
errors are ignored. Comments are denoted by a line starting with a
pound sign "#". The recognized commands include those supported by
the base class, plus a few more. The commands are case
insensitive, but are usually capitalized. The number of data sets
to be plotted does not need to be specified. Data sets are added as needed.
Each dataset is identified with a color (see the base class).
<P>
The appearance of the histogram can be altered by the following commands:
<pre>
Bars: <i>width</i>
Bars: <i>width, offset</i>
</pre>
The <i>width</i> is a real number specifying the width of the bars
as a fraction of the bin width. It usually has a value less than
or equal to one,
and defaults to 0.5. The <i>offset</i> is a real number
specifying how much the bar of the <i>i </i><sup>th</sup> data set
is offset from the previous one. This allows bars to "peek out"
from behind the ones in front. It defaults to 0.15.
Note that the frontmost data set will be the first one.
<p>
The width of each bin of the histogram can be specified using:
<pre>
BinWidth: <i>width</i>
</pre>
This is given in whatever units the data has.
By default, each bin is centered at <i>x</i> = <i>nw</i>,
where <i>w</i> is the width of the bin and <i>n</i> is an integer.
That bin represents values in the range (<i>x - w/2, x + w/2</i>).
The alignment of the bins can be changed with the following command:
<pre>
BinOffset: <i>offset</i>
</pre>
If this method is used with argument <i>o</i>, then each bin is
centered at <i>x = nw + o</i>, and represents values in the range
(<i>x - w/2 + o, x + w/2 + o</i>). So for example, if <i>o = w/2</i>,
then each bin represents values from <i>nw</i> to
(<i>n</i> + 1)<i>w</i> for some integer <i>n</i>.
The default offset is 0.5, half the default bin width.
<p>
To specify data to be plotted, start a data set with the following command:
<pre>
DataSet: <i>string</i>
</pre>
Here, <i>string</i> is a label that will appear in the legend.
It is not necessary to enclose the string in quotation marks.
To start a new dataset without giving it a name, use:
<pre>
DataSet:
</pre>
In this case, no item will appear in the legend.
New datasets are plotted <i>behind</i> the previous ones.
The data itself is given by a sequence of numbers, one per line.
The numbers are specified as
strings that can be parsed by the Double parser in Java.
It is also possible to specify the numbers using all the formats
accepted by the Plot class, so that the same data may be plotted by
both classes. The <i>x</i> data is ignored, and only the <i>y</i>
data is used to calculate the histogram.

/**
Plot signals dynamically, where points can be added at any time
and the display will be updated. This should be normally used
with some finite persistence so that old points are erased as new
points are added. Unfortunately, the most efficient way to erase
old points is to draw graphics using the "exclusive or" mode, which
introduces quite a number of artifacts. When lines are drawn
between points, where they overlap the points the line becomes
white. Moreover, if two lines or points overlap completely, they
disappear.
<p>
This class is abstract, so it must be used by creating a derived
class. To use it, create a derived class with an
addPoints() method. Your class may also set graph parameters like
titles and axis labels in the constructor by calling
methods in the Plot or PlotBox classes (both of which are base classes).
The addPoints() method should call addPoint() of the Plot base
class to dynamically add points to the plot. This method is called
within a thread separate from the applet thread, so the zooming
mechanism and buttons remain live.

//// PlotApplication
/**
PlotApplication is a versatile two-dimensional data plotter application.
It can read files compatible with the Ptolemy plot
file format (currently only ASCII). For a description of the file
format, see the Plot and PlotBox classes.
Command-line options include:
<dl>
<dt><code>-help</code></a>
<dt>Print the usage, including all command-line options
that exist for backward compatibility and then exit.
The help menu choice will display the same information.
<dt><code>-test</code></a>
<dt>Display the plot, then exit after 2 seconds.
<dt><code>-version</code></a>
<dt>Print the program version and then exit.
While ptplot is running,
the version menu choice will display the same information.
<dt><code>-</code></a>
<dt>Read the plot data from standard in.
</dl>
<p>
For compatibility with historical applications, this application has
a limited ability to read pxgraph files. The command line arguments
must be used, and the options that are understood are exactly those
of the pxgraph application, plus some more to allow for cross-platform
reading. It is not possible to read pxgraph files
using the "Open" menu command (because of the cross-platform problems).
The additional command-line arguments are:
<dl>
<dt><code>-bigendian</code></a>
<dt>Data files are in big-endian, or network binary format.
If you are on a little-endian machine, such as a machine
with an Intel x86 chip, and you would like to read a binary
format file created on a big-endian machine, such as a Sun SPARC,
use the <code>-bigendian</code> flag.
<dt><code>-littleendian</code></a>
<dt>Data files are in little-endian, or x86 binary format.
If you are on a big-endian machine, such as a Sun Sparc,
and you would like to read a binary
format file created on a little-endian machine, such as Intel x86
machine, then use the <code>-littleendian</code> flag.
</dl>
<p>
To compile and run this application, do the following:
<pre>
javac -classpath ../.. PlotApplication.java
java -classpath ../.. ptolemy.plot.PlotApplication
</pre>
<p>
This assumes a particular directory structure. If this is not what you
have, then alter the above accordingly.

//// EditablePlot
/**
This extension of Plot permits interactive modification of plotted
data, one dataset at a time. By default, you can modify dataset
number zero (the first one given). To change this default, call
setEditable(). To edit a plot, use the right mouse button.
Click and drag to the left to trace out new values for the data.
To read back the modified data, use getData(). To undo a change to
the data, type Control-Z. To redo the change, type Control-Y.
The undo history is infinite.
<p>
The style of editing is very particular. This class assumes the data
specify a function of <i>x</i>. I.e., there there is exactly one
<i>y</i> value for every <i>x</i> value. Thus, with the right mouse
button, you are allowed to trace out new <i>y</i> values
starting with some leftmost <i>x</i> value. You can only trace
values to the right. This feature makes it easy to trace values
with discontinuities. Just start at the left, and drag to the right
to the point of the discontinuity, then drag to the left,
then right again. You will have to try it...
Notice that this style of editing probably does not make sense with
error bars, since there is no mechanism for editing the error bars.
<p>
To be able to modify the data in a dataset, of course, there must
be data in the dataset. Thus, you should create a dataset (for
example by calling addPoint()) before editing it. Only the visible
part of the dataset can be edited (that is, the portion of the dataset
along the visible part of the horizontal axis). If you zoom in, then,
you can edit particular points more precisely.
<p>
To be notified when the user sketches a new signal, create an
object that implements the EditListener interface and add that
listener using addEditListener().

//// Plot
/**
A flexible signal plotter. The plot can be configured and data can
be provided either through a file with commands or through direct
invocation of the public methods of the class.
<p>
When calling the public methods, in most cases the changes will not
be visible until paintComponent() is called. To request that this
be done, call repaint(). One exception is addPoint(), which
makes the new point visible immediately if the plot is visible on
the screen and addPoint() is called from the event dispatching thread.
<p>
This base class supports a simple file syntax that has largely been
replaced by the XML-based PlotML syntax. To read a file or a
URL in this older syntax, use the read() method.
This older syntax contains any number commands,
one per line. Unrecognized commands and commands with syntax
errors are ignored. Comments are denoted by a line starting with a
pound sign "#". The recognized commands include those supported by
the base class, plus a few more. The commands are case
insensitive, but are usually capitalized. The number of data sets
to be plotted does not need to be specified. Data sets are added as needed.
Each dataset can be optionally identified with
color (see the base class) or with unique marks. The style of
marks used to denote a data point is defined by one of the following
commands:
<pre>
Marks: none
Marks: points
Marks: dots
Marks: various
Marks: pixels
</pre>
Here, "points" are small dots, while "dots" are larger. If "various"
is specified, then unique marks are used for the first ten data sets,
and then recycled. If "pixels" are specified, then each point is
drawn as one pixel.
Using no marks is useful when lines connect the points in a plot,
which is done by default. However, if persistence is set, then you
may want to choose "pixels" because the lines may overlap, resulting
in annoying gaps in the drawn line.
If the above directive appears before any DataSet directive, then it
specifies the default for all data sets. If it appears after a DataSet
directive, then it applies only to that data set.
<p>
To disable connecting lines, use:
<pre>
Lines: off
</pre>
To reenable them, use
<pre>
Lines: on
</pre>
You can also specify "impulses", which are lines drawn from a plotted point
down to the x axis. Plots with impulses are often called "stem plots."
These are off by default, but can be turned on with the
command:
<pre>
Impulses: on
</pre>
or back off with the command
<pre>
Impulses: off
</pre>
If that command appears before any DataSet directive, then the command
applies to all data sets. Otherwise, it applies only to the current data
set.
To create a bar graph, turn off lines and use any of the following commands:
<pre>
Bars: on
Bars: <i>width</i>
Bars: <i>width, offset</i>
</pre>
The <i>width</i> is a real number specifying the width of the bars
in the units of the x axis. The <i>offset</i> is a real number
specifying how much the bar of the <i>i</i><sup>th</sup> data set
is offset from the previous one. This allows bars to "peek out"
from behind the ones in front. Note that the frontmost data set
will be the first one. To turn off bars, use
<pre>
Bars: off
</pre>
To specify data to be plotted, start a data set with the following command:
<pre>
DataSet: <i>string</i>
</pre>
Here, <i>string</i> is a label that will appear in the legend.
It is not necessary to enclose the string in quotation marks.
To start a new dataset without giving it a name, use:
<pre>
DataSet:
</pre>
In this case, no item will appear in the legend.
New datasets are plotted <i>behind</i> the previous ones.
If the following directive occurs:
<pre>
ReuseDataSets: on
</pre>
Then datasets with the same name will be merged. This makes it
easier to combine multiple datafiles that contain the same datasets
into one file. By default, this capability is turned off, so
datasets with the same name are not merged.
The data itself is given by a sequence of commands with one of the
following forms:
<pre>
<i>x</i>, <i>y</i>
draw: <i>x</i>, <i>y</i>
move: <i>x</i>, <i>y</i>
<i>x</i>, <i>y</i>, <i>yLowErrorBar</i>, <i>yHighErrorBar</i>
draw: <i>x</i>, <i>y</i>, <i>yLowErrorBar</i>, <i>yHighErrorBar</i>
move: <i>x</i>, <i>y</i>, <i>yLowErrorBar</i>, <i>yHighErrorBar</i>
</pre>
The "draw" command is optional, so the first two forms are equivalent.
The "move" command causes a break in connected points, if lines are
being drawn between points. The numbers <i>x</i> and <i>y</i> are
arbitrary numbers as supported by the Double parser in Java.
If there are four numbers, then the last two numbers are assumed to
be the lower and upper values for error bars.
The numbers can be separated by commas, spaces or tabs.
<p>Some of the methods, such as those that add points a plot, are
executed in the event thread, possibly some time after they are called.
If they are called from a thread different from the event thread,
then the order in which changes to the plot take effect may be
surprising. We recommend that any code you write that changes
the plot in visible ways be executed in the event thread. You
can accomplish this using the following template:
<pre>
Runnable doAction = new Runnable() {
public void run() {
... make changes here (e.g. setMarksStyle()) ...
}
};
plot.deferIfNecessary(doAction);
</pre>
<p>
This plotter has some <A NAME="ptplot limitations">limitations</a>:
<ul>
<li> If you zoom in far enough, the plot becomes unreliable.
In particular, if the total extent of the plot is more than
2<sup>32</sup> times extent of the visible area, quantization
errors can result in displaying points or lines.
Note that 2<sup>32</sup> is over 4 billion.
<li> The limitations of the log axis facility are listed in
the <code>_gridInit()</code> method in the PlotBox class.
</ul>

//// PlotBox
/**
This class provides a labeled box within which to place a data plot.
A title, X and Y axis labels, tick marks, and a legend are all supported.
Zooming in and out is supported. To zoom in, drag the mouse
downwards to draw a box. To zoom out, drag the mouse upward.
<p>
The box can be configured either through a file with commands or
through direct invocation of the public methods of the class.
<p>
When calling the methods, in most cases the changes will not
be visible until paintComponent() has been called. To request that this
be done, call repaint().
<p>
A small set of key bindings are provided for convenience.
They are:
<ul>
<li> Cntrl-c: Export the plot to the clipboard (in PlotML).
<li> D: Dump the plot to standard output (in PlotML).
<li> E: Export the plot to standard output in EPS format.
<li> F: Fill the plot.
<li> H or ?: Display a simple help message.
<li> Cntrl-D or Q: quit
</ul>
These commands are provided in a menu by the PlotFrame class.
Note that exporting to the clipboard is not allowed in applets
(it used to be), so this will result in an error message.
<p>
At this time, the two export commands produce encapsulated postscript
tuned for black-and-white printers. In the future, more formats may
supported.
Exporting to the clipboard and to standard output, in theory,
is allowed for applets, unlike writing to a file. Thus, these
key bindings provide a simple mechanism to obtain a high-resolution
image of the plot from an applet, suitable for incorporation in
a document. However, in some browsers, exporting to standard out
triggers a security violation. You can use the JDK appletviewer instead.
<p>
To read commands from a file or URL, the preferred technique is
to use one of the classes in the plotml package. That package
supports both PlotML, an XML extension for plots, and a historical
file format specific to ptplot. The historical file format is
understood by the read() method in this class.
The syntax of the historical format, documented below, is rudimentary,
and will probably not be extended as ptplot evolves. Nonetheless,
we document it here since it is directly supported by this class.
<p>
The historical format for the file allows any number
commands, one per line. Unrecognized commands and commands with
syntax errors are ignored. Comments are denoted by a line starting
with a pound sign "#". The recognized commands include:
<pre>
TitleText: <i>string</i>
XLabel: <i>string</i>
YLabel: <i>string</i>
</pre>
These commands provide a title and labels for the X (horizontal) and Y
(vertical) axes.
A <i>string</i> is simply a sequence of characters, possibly
including spaces. There is no need here to surround them with
quotation marks, and in fact, if you do, the quotation marks will
be included in the labels.
<p>
The ranges of the X and Y axes can be optionally given by commands like:
<pre>
XRange: <i>min</i>, <i>max</i>
YRange: <i>min</i>, <i>max</i>
</pre>
The arguments <i>min</i> and <i>max</i> are numbers, possibly
including a sign and a decimal point. If they are not specified,
then the ranges are computed automatically from the data and padded
slightly so that datapoints are not plotted on the axes.
<p>
The tick marks for the axes are usually computed automatically from
the ranges. Every attempt is made to choose reasonable positions
for the tick marks regardless of the data ranges (powers of
ten multiplied by 1, 2, or 5 are used). However, they can also be
specified explicitly using commands like:
<pre>
XTicks: <i>label position, label position, ...</i>
YTicks: <i>label position, label position, ...</i>
</pre>
A <i>label</i> is a string that must be surrounded by quotation
marks if it contains any spaces. A <i>position</i> is a number
giving the location of the tick mark along the axis. For example,
a horizontal axis for a frequency domain plot might have tick marks
as follows:
<pre>
XTicks: -PI -3.14159, -PI/2 -1.570795, 0 0, PI/2 1.570795, PI 3.14159
</pre>
Tick marks could also denote years, months, days of the week, etc.
<p>
The X and Y axes can use a logarithmic scale with the following commands:
<pre>
XLog: on
YLog: on
</pre>
The grid labels represent powers of 10. Note that if a logarithmic
scale is used, then the values must be positive. Non-positive values
will be silently dropped. Note further that when using logarithmic
axes that the log of input data is taken as the data is added to the plot.
This means that <pre>XLog: on</pre> or <pre>YLog: on</pre> should
appear before any data. Also, the value of the XTicks, YTicks,
XRange or YRange directives should be in log units.
So, <pre>XTicks: 1K 3</pre> will display the string <pre>1K</pre>
at the 1000 mark.
<p>
By default, tick marks are connected by a light grey background grid.
This grid can be turned off with the following command:
<pre>
Grid: off
</pre>
It can be turned back on with
<pre>
Grid: on
</pre>
Also, by default, the first ten data sets are shown each in a unique color.
The use of color can be turned off with the command:
<pre>
Color: off
</pre>
It can be turned back on with
<pre>
Color: on
</pre>
Finally, the rather specialized command
<pre>
Wrap: on
</pre>
enables wrapping of the X (horizontal) axis, which means that if
a point is added with X out of range, its X value will be modified
modulo the range so that it lies in range. This command only has an
effect if the X range has been set explicitly. It is designed specifically
to support oscilloscope-like behavior, where the X value of points is
increasing, but the display wraps it around to left. A point that lands
on the right edge of the X range is repeated on the left edge to give
a better sense of continuity. The feature works best when points do land
precisely on the edge, and are plotted from left to right, increasing
in X.
<p>
All of the above commands can also be invoked directly by calling the
the corresponding public methods from some Java procedure.
<p>
This class uses features of JDK 1.2, and hence if used in an applet,
it can only be viewed by a browser that supports JDK 1.2, or a plugin.

//// PlotFrame
/**
PlotFrame is a versatile two-dimensional data plotter that runs as
part of an application, but in its own window. It can read files
compatible with the old Ptolemy plot file format (currently only ASCII).
It is extended with the capability to read PlotML files in PlotMLFrame.
An application can also interact directly with the contained Plot
object, which is visible as a public member, by invoking its methods.
<p>
An application that uses this class should set up the handling of
window-closing events. Presumably, the application will exit when
all windows have been closed. This is done with code something like:
<pre>
plotFrameInstance.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
// Handle the event
}
});
</pre>
<p>
PlotFrame contains an instance of PlotBox. PlotBox is the base class for
classes with drawing capability, e.g. Plot, LogicAnalyzer. If not
specified in the constructor, the default is to contain a Plot object. This
field is set once in the constructor and immutable afterwards.

This is an interface for listeners that need to be informed when a

WindowListener interface does. This class is a workaround for a bug
in Java's AWT, where components are not informed in any way when the
window that contains them is closed, even though they can have
registered listeners. The listeners are never called, unless the
component is a top-level window. A listener that implements this
interface, by contrast, is informed regardless of whether it is
at the top level. This is used, for example, by the ComponentDialog
class.

/**
This class is a modal dialog box that contains an arbitrary component.
It can be used, for example, to put an instance of Query in a
top-level dialog box. The general way to use this class is to create
the component that you wish to have contained in the dialog.
Then pass that component to the constructor of this class. The dialog
is modal, so the statement that creates the dialog will not return
until the user dismisses the dialog. The method buttonPressed()
can then be called to find out whether the user clicked the OK button
or the Cancel button (or any other button specified in the constructor).
Then you can access the component to determine what values were set
by the user.
<p>
If the component that is added implements the CloseListener interface,
then that component is notified when this dialog closes.
