+NOTE: If you used the earlier APIs released by Versit

+then you will want to look at the document "migrate.doc"

+included with this package. It contains a discussion of

+the differences between the old API and this one.

+

+----------------------------------------------------------------

+

+The vCard/vCalendar C interface is implemented in the set 

+of files as follows:

+

+vcc.y, yacc source, and vcc.c, the yacc output you will use

+implements the core parser

+

+vobject.c implements an API that insulates the caller from

+the parser and changes in the vCard/vCalendar BNF

+

+port.h defines compilation environment dependent stuff

+

+vcc.h and vobject.h are header files for their .c counterparts

+

+vcaltmp.h and vcaltmp.c implement vCalendar "macro" functions

+which you may find useful.

+

+test.c is a standalone test driver that exercises some of

+the features of the APIs provided. Invoke test.exe on a

+VCARD/VCALENDAR input text file and you will see the pretty

+print output of the internal representation (this pretty print

+output should give you a good idea of how the internal 

+representation looks like -- there is one such output in the 

+following too). Also, a file with the .out suffix is generated 

+to show that the internal representation can be written back 

+in the original text format.

+Table of Contents

+2. Internal Representations of VCard/VCalendar

+3. Iterating Through VObject's Properties or Values

+4. Pretty Printing a VObject Tree

+5. Building A VObject Representation of A VCard/VCalendar

+6. Converting A VObject Representation Into Its Textual Representation

+7. Miscellaneous Notes On VObject APIs usages

+8. Brief descriptions of each APIs

+9. Additional Programming Notes.

+

+This document is mainly about the VObject and its APIs. The main

+use of a VObject is to represent a VCard or a VCalendar inside

+a program. However, its use is not limited to aforemention as it

+can represent an arbitrary information that makes up of a tree or

+forest of properties/values.

+

+1. VObject

+   =======

+A VObject can have a name (id) and a list of associated properties and

+a value. Each property is itself a VObject.

+

+2. Internal Representations of VCard/VCalendar

+   ===========================================

+A list of VCard or a VCalendar is represented by a list of VObjects.

+The name (id) of the VObjects in the list is either VCCardProp or

+VCCalProp. Each of these VObjects can have a list of properties.

+Since a property is represented as a VObject, each of these properties

+can have a name, a list of properties, and a value.

+

+For example, the input file "vobject.vcf":

+will conceptually be be represented as

+    vcard

+	VCNameProp

+	    VCFamilyNameProp=Alden

+	    VCGivenNameProp=Roland

+	VCFullNameProp=Roland H.Alden

+	....

+	

+note that

+    EMAIL;WORK;PREF;INTERNET:sf!rincon!ralden@alden.attmail.com

+will be represented as:

+	VCEmailAddress=sf!rincon!ralden@alden.attmail.com

+	    VCWork

+	    VCPreferred

+	    VCInternet

+where the lower level properties are properties of the property

+VCEmailAddress.

+

+Groupings are flattened out in the VObject representation such

+that:

+	a.b:blah

+	a.c:blahblah

+are represented as:

+	b=blah

+	    VCGrouping=a

+	c=blahblah

+	    VCGrouping=a

+i.e. one can read the above as:

+	 the property "b" has value "blah" and property "VCGrouping"

+		with the value "a".

+	 the property "c" has value "blahblah" and property "VCGrouping"

+		with the value "a".

+likewise, multi-level groupings are flatten similarly. e.g.

+	a.b.c:blah

+	a.b.e:blahblah

+-->

+	c=blah

+	    VCGrouping=b

+		VCGrouping=a

+	e=blahblah

+	    VCGrouping=b

+		VCGrouping=a

+which read:

+	 the property "c" has value "blah" and property "VCGrouping"

+		with the value "b" which has property "VCGrouping"

+		with value "a".

+	 the property "e" has value "blahblah" and property "VCGrouping"

+		with the value "b" which has property "VCGrouping"

+		with value "a".

+

+3. Iterating Through VObject's Properties or Values

+   ================================================

+The following is a skeletal form of iterating through

+all properties of a vobject, o:

+

+    // assume the object of interest, o, is of type VObject

+    VObjectIterator i;

+    initPropIterator(&i,o);

+    while (moreIteration(&i)) {

+	VObject *each = nextVObject(&i);

+	// ... do something with "each" property 

+	}

+

+Use the API vObjectName() to access a VObject's name.

+Use the API vObjectValueType() to determine if a VObject has

+	a value. For VCard/VCalendar application, you

+	should not need this function as practically

+	all values are either of type VCVT_USTRINGZ or

+	VCVT_RAW (i.e set by setVObjectUStringZValue and

+	setVObjectAnyValue APIs respectively), and the

+	value returned by calls to vObjectUStringZValue

+	and vObjectAnyValue are 0 if a VObject has no

+	value. (There is a minor exception where VObject with

+	VCDataSizeProp has value that is set by

+	setVObjectLongValue).

+Use the APIs vObject???Value() to access a VObject's value.

+	where ??? is the expected type.

+Use the APIs setvObject???Value() to set or modify a VObject's value.

+	where ??? is the expected type.

+Use the API isAPropertyOf() to query if a name match the name of

+	a property of a VObject. Since isAPropertyOf() return

+	the matching property, we can use that to retrieve

+	a property and subsequently the value of the property.

+

+4. Pretty Printing a VObject Tree

+   ==============================

+VObject tree can be pretty printed with the printVObject() function.

+The output of pretty printing a VObject representation of the input

+test file "vobject.vcf" is shown below. Note that the indentation

+indicates the tree hirerarchy where the immediate children nodes

+of a parent node is all at the same indentation level and the

+immediate children nodes are the immediate properties of the

+associated parent nodes.  In the following, {N,FN,ORG,TITLE,...}

+are immediate properties of VCARD. {F and G} are properties of N

+with value {"Alden" and "Roland"} respectively; FN has no property

+but has the value "Roland H. Alden"; EMAIL has value and

+the properties WORK, PREF, and INTERNET.

+

+

+VCARD

+5. Building A VObject Representation of A VCard/VCalendar

+   ======================================================

+The parser in vcc.y converts an input file with one or more

+VCard/VCalendar that is in their textual representation

+into their corresponding VObject representation.

+

+VObject representation of a VCard/VCalendar can also be built

+directly with calls to the VObject building APIs. e.g.

+

+	VObject *prop;

+	VObject *vcard = newVObject(VCCardProp);

+	prop = addProp(vcard,VCNameProp);

+		addPropValue(prop,VCFamilyNameProp,"Alden");

+		addPropValue(prop,VCGivenNameProp,"Roland");

+	addPropValue(vcard,VCFullNameProp,"Roland H. Alden");

+	....

+

+6. Converting A VObject Representation Into Its Textual Representation

+   ===================================================================

+The VObject representation can be converted back to its textual

+representation via the call to writeVObject() or writeMemVObject()

+API. e.g.

+   a. to write to a file:

+	// assume vcard is of type VObject

+	FILE *fp = fopen("alden.vcf","w");

+	writeVObject(fp,vcard);

+   a. to write to memory, and let the API allocate the required memory.

+	char* clipboard = writeVObject(0,0,vcard);

+	... do something to clipboard

+	free(clipboard);

+   b. to write to a user allocated buffer:

+	char clipboard[16384];

+	int len = 16384;

+	char *buf  = writeVObject(clipboard,&len,vcard);

+	... buf will be equal to clipboard if the write

+	is successful otherwise 0.

+

+In the case of writing to memory, the memory buffer can be either

+allocated by the API or the user. If the user allocate the

+memory for the buffer, then the length of the buffer needs to be

+communicated to the API via a variable. The variable passed as

+the length argument will be overwritten with the actual size

+of the text output. A 0 return value from writeMemVObject()

+indicates an error which could be caused by overflowing the

+size of the buffer or lack of heap memory.

+

+7. Miscellaneous Notes On VObject APIs usages

+   ==========================================

+a. vcc.h -- contains basic interfaces to the parser:

+    VObject* Parse_MIME(const char *input, unsigned long len);

+    VObject* Parse_MIME_FromFile(FILE *file);

+	-- both of this return a null-terminated list of

+	   VObject that is either a VCARD or VCALENDAR.

+	   To iterate through this list, do

+		VObject *t, *v;

+		v = Parse_Mime_FromFile(fp);

+		while (v) {

+		    // ... do something to v.

+		    t = v;

+		    v = nextVObjectInList(v);

+		    cleanVObject(t);

+		    }

+	    note that call to cleanVObject will release

+	    resource used to represent the VObject.

+

+b. vobject.h -- contains basic interfaces to the VObject APIs.

+	see the header for more details.

+	The structure of VObject is purposely (hiddened) not exposed

+	to the user. Every access has to be done via

+	the APIs. This way, if we need to change the

+	structure or implementation, the client need not

+	recompile as long as the interfaces remain the

+	same.

+

+c. values of a property is determined by the property definition

+	itself. The vobject APIs does not attempt to enforce

+	any of such definition. It is the consumer responsibility

+	to know what value is expected from a property. e.g

+	most properties have unicode string value, so to access

+	the value of these type of properties, you will use

+	the vObjectUStringZValue() to read the value and

+	setVObjectUStringZValue() to set or modify the value.

+	Refer to the VCard and VCalendar specifications for

+	the definition of each property.

+

+d. properties name (id) are case incensitive.

+

+8. Brief descriptions of each APIs

+   ===============================

+   * the predefined properties' names (id) are listed under vobject.h

+	each is of the form VC*Prop. e.g.

+		#define VC7bitProp		"7BIT"

+		#define VCAAlarmProp	"AALARM"

+		....

+

+   * consumer of a VObject can only define pointers to VObject.

+

+   * a variable of type VObjectIterator, say "i", can be used to iterate

+	through a VObject's properties, say "o". The APIs related to

+	VObjectIterator are:

+		void initPropIterator(VObjectIterator *i, VObject *o);

+			-- e.g. usage

+				initPropIterator(&i,o);

+		int moreIteration(VObjectIterator *i);

+			-- e.g. usage

+				while (moreIteration(&i)) { ... }

+		VObject* nextVObject(VObjectIterator *i);

+			-- e.g. usage

+				while (moreIteration(&i)) {

+				    VObject *each = nextVObject(&i);

+				    }

+

+    * VObject can be chained together to form a list. e.g. of such

+	use is in the parser where the return value of the parser is

+	a link list of VObject. A link list of VObject can be

+	built by:

+		void addList(VObject **o, VObject *p);

+	and iterated by

+		VObject* nextVObjectInList(VObject *o);

+			-- next VObjectInList return 0 if the list

+				is exhausted.

+

+    * the following APIs are mainly used to construct a VObject tree:

+	VObject* newVObject(const char *id);

+	    -- used extensively internally by VObject APIs but when

+		used externally, its use is mainly limited to the

+		construction of top level object (e.g. an object

+		with VCCardProp or VCCalendarProp id).

+	

+	void deleteVObject(VObject *p);

+	    -- to deallocate single VObject, for most user, use

+		cleanVObject(VObject *o) instead for freeing all

+		resources associated with the VObject.

+

+	char* dupStr(const char *s, unsigned int size);

+	    -- duplicate a string s. If size is 0, the string is

+		assume to be a null-terminated. 

+

+	void deleteStr(const char *p);

+	    -- used to deallocate a string allocated by dupStr();

+

+	void setVObjectName(VObject *o, const char* id);

+	    -- set the id of VObject o. This function is not

+		normally used by the user. The setting of id

+		is normally done as part of other APIs (e.g.

+		addProp()).

+

+	void setVObjectStringZValue(VObject *o, const char *s);

+	    -- set a string value of a VObject.

+

+	    -- set a Unicode string value of a VObject.

+

+	void setVObjectIntegerValue(VObject *o, unsigned int i);

+	    -- set an integer value of a VObject.

+

+	void setVObjectLongValue(VObject *o, unsigned long l);

+	    -- set an long integer value of a VObject.

+

+	void setVObjectAnyValue(VObject *o, void *t);

+	    -- set any value of a VObject. The value type is

+		unspecified.

+

+	VObject* setValueWithSize(VObject *prop, void *val, unsigned int size);

+	    -- set a raw data (stream of bytes) value of a VObject

+		whose size is size. The internal VObject representation

+		is

+			this object = val

+			    VCDataSizeProp=size

+		i.e. the value val will be attached to the VObject prop

+		and a property of VCDataSize whose value is size

+		is also added to the object.

+		

+	void setVObjectVObjectValue(VObject *o, VObject *p);

+	    -- set a VObject as the value of another VObject.

+		    o

+			c

+			   VCGroupingProp=b

+			       VCGroupingProp=a

+		and the object c is returned.

+

+

+	char* writeMemVObject(char *s, int *len, VObject *o);

+	     -- convert VObject o to its textual representation and

+		write it to memory. If s is 0, then memory required

+		to hold the textual representation will be allocated

+		by this API. If a variable len is passed, len will

+		be overwriten with the byte size of the textual

+		representation. If s is non-zero, then s has to

+		be a user allocated buffer whose size has be passed

+		in len as a variable. Memory allocated by the API

+		has to be freed with call to free. The return value

+		of this API is either the user supplied buffer,

+		the memory allocated by the API, or 0 (in case of

+		failure).

+

+	void cleanStrTbl();

+		-- this function has to be called when all

+		VObject has been destroyed.

+

+9. Additional Programming Notes

+   ============================

+In the following notes, please refers to the listing

+of Example.vcf and its VObject Representation

+(shown at the end of this section).

+

+* Handling the Return Value of the VCard/VCalendar Parser

+    The example input text file contains two root VObjects

+    (a VCalendar and a VCard). The output of the VCard/VCalendar

+    parser is a null-terminated list of VObjects. For this

+    particular input file, the list will have two VObjects.

+    The following shows a template for iterating through the

+    output of the Parser:

+

+	VObject *t, *v;

+	v = Parse_Mime_fromFileName("example.vcf");

+	while (v) {

+	    // currently, v will either be a VCard or a VCalendar

+	    //	do whatever your application need to do to

+	    //  v here ...

+	    t = v;

+	    v = nextVObjectInList(v);

+	    cleanVObject(t);

+	    }

+

+* Iterating Through a VCard/VCalendar VObject

+    From the VObject APIs point of view, a VCard VObject

+    is the same as a VCalendar VObject. However, the application

+    needs to know what are in a VCard or a VCalendar.

+    For example, A VCalendar VObject can have VCDCreatedProp,

+    a VCGEOLocationProp, etc, and one or more VCEventProp and

+    or VCTodoProp. The VCEventProp and VCTodoProp can have

+    many properties of their own, which in turn could have

+    more properties (e.g. VCDAlarmProp can be a VCEventProp

+    VObject's property, and VCRunTimeProp can be a

+    VCDAlarmProp VObject's property. Because a VObject tree

+    can be arbitrarily complex, in general, to process all

+    properties and values of a VObject tree, a recursive walk

+    is desirable. An example recursive VObject tree walk

+    can be found in the vobject.c source lines for printVObject*

+    and writeVObject* APIs. Depending on what the application need

+    to do with a VCard or a VCalendar, a recursive walk

+    of the VObject tree may or may not be desirable. An example

+    template of a non-recursive walk is shown below:

+	

+    void processVCardVCalendar(char *inputFile)

+    {

+	VObject *t, *v;

+	v = Parse_Mime_fromFileName(inputFile);

+	while (v) {

+	    char *n = vObjectName(v);

+	    if (strcmp(n,VCCardProp) == 0) {

+		do_VCard(v);

+		}

+	    else if (strcmp(n,VCCalendarProp) == 0) {

+		do_VCalendar(v);

+		}

+	    else {

+		// don't know how to handle anything else!

+		}

+	    t = v;

+	    v = nextVObjectInList(v);

+	    cleanVObject(t);

+	    }

+    }

+

+    void  do_VCard(VObject *vcard)

+    {

+	VObjectIterator t;

+	initPropIterator(&t,vcard);

+	while (moreIteration(&t)) {

+	    VObject *eachProp = nextVObject(&t);

+	    //	The primarly purpose of this example is to

+	    //  show how to iterate through a VCard VObject,

+	    //	it is not meant to be efficient at all.

+	    char *n = vObjectName(eachProp);

+	    if (strcmp(n,VCNameProp)==0) {

+		do_name(eachProp);

+		}

+	    else if (strcmp(n,VCEmailProp)==0) {

+		do_email(eachProp);

+		}

+	    else if (strcmp(n,VCLabelProp)==0) {

+		do_label(eachProp);

+		}

+	    else if ....

+	    }

+    }

+

+    void  do_VCalendar(VObject *vcal)

+    {

+	VObjectIterator t;

+	initPropIterator(&t,vcard);

+	while (moreIteration(&t)) {

+	    VObject *eachProp = nextVObject(&t);

+	    //	The primarly purpose of this example is to

+	    //  show how to iterate through a VCalendar VObject,

+	    //	it is not meant to be efficient at all.

+	    char *n = vObjectName(eachProp);

+	    if (strcmp(n,VCDCreatedProp)==0) {

+		do_DCreated(eachProp);

+		}

+	    else if (strcmp(n,VCVersionProp)==0) {

+		do_Version(eachProp);

+		}

+	    else if (strcmp(n,VCTodoProp)==0) {

+		do_Todo(eachProp);

+		}

+	    else if (strcmp(n,VCEventProp)==0) {

+		do_Event(eachProp);

+		}

+	    else if ....

+	    }

+    }

+

+    void do_Todo(VObject *vtodo) { ... }

+

+    void do_Event(VObject *vevent) { ... }

+

+    ...

+    

+* Property's Values and Properties

+    The VObject APIs do not attempt to check for the

+    correctness of the values of a property. Nor do they

+    will prevent the user from attaching a non-VCard/VCalendar

+    standard property to a VCard/VCalendar property. Take

+    the example of line [11] of the example, "O.K" is not

+    a valid value of VCStatusProp.  It is up to the application

+    to accept or reject the value of a property.

+    

+* Output of printVObject

+    PrintVObject pretty prints a VObject tree in human

+    readable form. See the listing at the end of the file

+    for an example output of printVObject on the example

+    input file "Example.vcf".

+

+    Note that binary data are not shown in the output of

+    printVObject. Instead, a note is made ([raw data]) to

+    indicate that there exists such a binary data.

+

+* Note on Binary Data

+    When the value of a property is a binary data, it is only

+    useful to know the size of the binary data.

+

+    In the case of the VCard/VCalendar parser, it chooses

+    to represent the size information as a separate property

+    called VCDataSizeProp whose value is the size of the binary

+    data. The APIs sequence to construct the VObject subtree

+    of line [44] of Example.vcf is

+

+	    // VObject *vcard;

+	    VObject *p1 = addProp(vcard,VCLogoProp);

+	    (void) addProp(p1,VCGIFProp);

+	    (void) addProp(p1,VCBASE64Prop);

+	    VObject *p2 = addProp(p1,VCDataSizeProp);

+	    (void) setVObjectLongValue(p2,1482);

+	    setVObjectAnyValue(vcard,...pointer to binary data);

+	

+    Note the presence of VCBase64Prop will cause the

+    writeVObject API to output the binary data as BASE64 text.

+    For VCard/VCalendar application, having the VCBase64Prop

+    property is practically always necessary for property with

+    binary data as its value.

+	

+* Note on Quoted-Printable String

+    String value with embedded newline are written out as

+    quoted-prinatable string. It is therefore important

+    to mark a property with a string value that has

+    one or more embedded newlines, with the VCQutedPrintableProp

+    property. e.g.

+			

+	// VObject *root;

+	char *msg="To be\nor\nnot to be";

+	VObject *p = addPropValue(root,VCDescriptionProp,msg);

+	    // the following is how you mark a property with

+	    //	a property. In this case, the marker is

+	    //  VCQuotedPrintableProp

+	    addProp(p,VCQuotedPrintableProp);

+

+* Note on Unicode

+    Although, the current parser takes ASCII text file only,

+    string values are all stored as Unicode in the VObject tree.

+    For now, when using the VObject APIs to construct a

+    VObject tree, one should always convert ASCII string value

+    to a Unicode string value:

+

+	// VObject *root;

+	VObject *p = addProp(root,VCSomeProp);

+	setVObjectUStringZValue(p,fakeUnicode(someASCIIStringZvalue));

+

+    An API is provided to simplify the above process:

+

+	addPropValue(root,VCSomeProp,someASCIIStringZValue);

+

+    Note that someASCIISTringZValue is automatically converted to

+    Unicode by addPropValue API, where as, the former code

+    sequence do an explicit call to fakeUnicode.

+

+    To read back the value, one should use the vObjectUStringZValue

+    API not vObjectStringZValue API. The value returned by the

+    vObjectUStringZValue API is a Unicode string. If the application

+    do not know how to handle Unicode string, it can use the

+    fakeCString API to convert it back to ASCII string (as long

+    as the conversion is meaningful).

+

+    Note that fakeCString return a heap allocated memory. It is

+    important to call deleteStr on fakeCString return value if

+    it is not longer required (or there will be memory leak).

+

+    NOTE: Unfortunately, at the point when this document is written,

+    there is still no consensus on how Unicode is to be handled

+    in the textual representation of VCard/VCalendar. So, there

+    is no version of writeVObject and the parser to output and

+    input Unicode textual representation of VCard/VCalendar.

+  The icalvcal_convert routine calls icalvcal_traverse_objects to do

+  and components of a VObject. For each name of a property or a
+  component, icalvcal_traverse_objects looks up the name in
+  conversion_table[]. This table indicates wether the name is of a
+  component or a property, lists a routine to handle conversion, and
+  has extra data for the conversion.
+
+  The conversion routine will create new iCal components or properties
+  and add them to the iCal component structure. 
+
+  The most common conversion routine is dc_prop. This routine converts
+  properties for which the text representation of the vCal component
+  is identical the iCal representation.

+
+   MALARM has Run Time, Snooze Time, Repeat Count, Email Address, Note.

+   UTC using the current Unix timezone.
+
+   The Snooze Time becomes DURATION, and the Repeat Count becomes REPEAT.

+   WAVE -> 'audio/x-wav', AIFF -> 'audio/x-aiff'), e.g.
+     ATTACH;FMTTYPE=audio/basic:ftp://host.com/pub/sounds/bell-01.aud
+
+   For DALARM, Display String becomes the DESCRIPTION property.
+
+   For MALARM, Email Address becomes an ATTENDEE property, e.g.
+     ATTENDEE:MAILTO:john_doe@host.com
+
+   For PALARM, the Procedure Name becomes an ATTACH property, like AALARM, e.g.

+	are mutually exclusive in iCalendar. For now we just use the COUNT.
+     2) For MONTHLY By Position recurrences, if no modifiers are given they
+        are to be calculated based on the DTSTART, e.g. if DTSTART is on the
+	3rd Wednesday of the month then all occurrences are on the 3rd Wed.
+	This is awkward to do as we need to access the DTSTART property, which
+	may be after the RRULE property. So we don't do this at present.
+     3) The Extended Recurrence Rule Grammar - we only support the Basic rules.

+
+Note on APIs:
+	1.	The APIs does not attempt to verify if the arguments
+		passed are correct.
+	2.	Where the argument to an API is not applicable, pass
+		the value 0.
+	3.	See the test program at the bottom of this file as an
+		example of usage.

+ 
+The vCard/vCalendar C interface is implemented in the set 
+of files as follows:
+
+vcc.y, yacc source, and vcc.c, the yacc output you will use
+implements the core parser
+
+vobject.c implements an API that insulates the caller from
+the parser and changes in the vCard/vCalendar BNF
+
+port.h defines compilation environment dependent stuff
+
+vcc.h and vobject.h are header files for their .c counterparts
+
+vcaltmp.h and vcaltmp.c implement vCalendar "macro" functions
+which you may find useful.
+
+test.c is a standalone test driver that exercises some of
+the features of the APIs provided. Invoke test.exe on a
+VCARD/VCALENDAR input text file and you will see the pretty
+print output of the internal representation (this pretty print
+output should give you a good idea of how the internal 
+representation looks like -- there is one such output in the 
+following too). Also, a file with the .out suffix is generated 
+to show that the internal representation can be written back 
+in the original text format.
+
+For more information on this API see the readme.txt file
+which accompanied this distribution.
