(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.

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 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.

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 pratically 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. + + +Example.vcf +----------- +line +number Input Text (example.vcf) +------ ---------- +1 BEGIN:VCALENDAR +2 DCREATED:19961102T100522 +3 GEO:0,0 +4 VERSION:1.0 +5 BEGIN:VEVENT +6 DTSTART:19961103T000000 +7 DTEND:20000101T000000 +8 DESCRIPTION;QUOTED-PRINTABLE:To be =0A= +9 or =0A= +10 not to be +11 STATUS:O.K. +12 X-ACTION:No action required +13 DALARM:19961103T114500;5;3;Enjoy +14 MALARM:19970101T120000;;;johny@nowhere.com;Call Mom. +15 END:VEVENT +16 +17 BEGIN:VTODO +18 DUE:19960614T0173000 +19 DESCRIPTION:Relex. +20 END:VTODO +21 +22 END:VCALENDAR +23 +24 BEGIN:VCARD +25 N:Alden;Roland +26 FN:Roland H.
