1. EXTRACT_LOCAL_CLASSES Ifthe EXTRACT LOCAL CLASSES tag is set to YES classes and structs defined locally in source files will be included in the documentation If set to NO only classes defined in header files are included Does not have any effect for Java sources EXTRACT ANON NSPACES If this flag is set to YES the members of anonymous namespaces will be extracted and appear in the documentation as a namespace called anonymous_namespace file where file will be replaced with the base name of the file that contains the anonymous namespace By default anonymous namespace are hidden EXTRACT LOCAL METHODS This flag is only useful for Objective C code When set to YES local meth ods which are defined in the implementation section but not in the interface are included in the documentation If set to NO the default only methods in the interface are included HIDE UNDOC MEMBERS If the HIDE UNDOC MEMBERS tag is set to YES doxygen will hide all undoc umented members inside documented classes or files If set to NO the default these members will be included in the various overviews but no documentation section is generated This option has no effect if EXTRACT ALL is enabled HIDE UNDOC CLASSES If the HIDE UNDOC CLASSESS tag is set to YES doxygen will hide all un documented classes If set to NO the default these classes will be included in the various overviews
2. Figure 1 Doxygen information flow 2 1 Step 1 Creating a configuration file Doxygen uses a configuration file to determine all of its settings Each project should get its own configura tion file A project can consist of a single source file but can also be an entire source tree that is recursively scanned To simplify the creation of a configuration file doxygen can create a template configuration file for you To do this call doxygen from the command line with the g option doxygen g config file where lt config file gt is the name of the configuration file If you omit the file name a file named Doxyfile will be created If a file with the name lt config file gt already exists doxygen will rename it to lt config file gt bak before generating the configuration template If you use i e the minus sign as the file name then doxygen will try to read the configuration file from standard input st din which can be useful for scripting The configuration file has a format that is similar to that of a simple Makefile It consists of a number of assignments tags of the form TAGNAME VALUE or User Manual for Doxygen 1 5 3 written by Dimitri van Heesch 1997 2006 2 2 Step 2 Running doxygen 12 TAGNAME VALUE1 VALUE2 You can probably leave the values of most tags in a generated template configuration file to their default value See section Configuration for more detai

5. The task of the parser is to convert the input buffer into a tree of entries basically an abstract syntax tree An entry is defined in src entry h andis blob of loosely structured information The most important field is sect ion which specifies the kind of information contained in the entry Possible improvements for future versions e Use one scanner parser per language instead of one big scanner e Move the first pass parsing of documentation blocks to a separate module e Parse defines these are currently gathered by the preprocessor and ignored by the language parser User Manual for Doxygen 1 5 3 written by Dimitri van Heesch 1997 2006 119 Data organizer This step consists of many smaller steps that build dictionaries of the extracted classes files namespaces variables functions packages pages and groups Besides building dictionaries during this step relations such as inheritance relations between the extracted entities are computed Each step has a function defined in src doxygen cpp which operates on the tree of entries built during language parsing Look at the Gathering information part of parseInput for details The result of this step is a number of dictionaries which can be found in the Doxygen namespace defined in src doxygen h Most elements of these dictionaries are derived from the class Definition The class MemberDef for instance holds all information for a member An instance

80. ave a different update frequency from your own project It does not make much sense to let doxygen parse the sources for these external project over and over again even if nothing has changed Memory For very large source trees letting doxygen parse all sources may simply take too much of your system s memory By dividing the sources into several packages the sources of one package can be parsed by doxygen while all other packages that this package depends on are linked in externally This saves a lot of memory Availability For some projects that are documented with doxygen the sources may just not be available User Manual for Doxygen 1 5 3 written by Dimitri van Heesch 1997 2006 42 Copyright issues If the external package and its documentation are copyright someone else it may be better or even necessary to reference it rather than include a copy of it with your project s doc umentation When the author forbids redistribution this is necessary If the author requires com pliance with some license condition as a precondition of redistribution and you do not want to be bound by those conditions referring to their copy of their documentation is preferable to including a copy If any of the above apply you can use doxygen s tag file mechanism A tag file is basically a compact representation of the entities found in the external sources Doxygen can both generate and read tag files To generate a tag file for you

208. using the ingroup command and then document the group using a comment block containing the defgroup command For member functions or functions that are part of a namespace you should document either the class or namespace 4 How can I make doxygen ignore some code fragment The new and easiest way is to add one comment block with a cond command at the start and one comment block with a endcond command at the end of the piece of code that should be ignored This should be within the same file of course But you can also use Doxygen s preprocessor for this If you put ifndef DOXYGEN SHOULD SKIP THIS code that must be skipped by Doxygen endif DOXYGEN SHOULD SKIP THIS around the blocks that should be hidden and put PREDEFINED DOXYGEN SHOULD SKIP THIS in the config file then all blocks should be skipped by Doxygen as long as PREPROCESSING YES 5 How can I change what is after the include in the class documentation In most cases you can use STRIP FROM INC PATH to strip a user defined part of a path You can also document your class as follows Nclass MyClassName include h path include h Docs for MyClassName x To make doxygen put finclude lt path include h gt in the documentation of the class MyClassName regardless of the name of the actual header file in which the definition of MyClassName is contained If you want doxygen to show that the include file should be include

211. wards build files are provided for Visual Studio 2005 Also the free as in beer Express version of Developer Studio can be used to compile doxygen Alternatively you can compile doxygen the Unix way using Cygwin or MinGW Before you can compile doxygen you need to download and install the C compiler of Visual Studio Since Microsoft apparently wants to lure everyone into using their NET stuff they made things somewhat difficult when you use the Express version You need to do some manual steps in order to setup a proper working environment for building native win32 applications such as Doxygen The next step is to install unxutils see http sourceforge net projects unxutils This packages contains the tools flex and bison which are needed during the compilation process if you use a CVS snapshot of doxygen the official source releases come with pre generated sources Download the zip extract it to e g c tools unxutils Now you need to add adjust the following environment X variables via Control Panel System Advanced Environment Variables User Manual for Doxygen 1 5 3 written by Dimitri van Heesch 1997 2006 1 5 Installing the binaries on Windows e add c tools unxutils usr local wbin to the start of PATH e set BISON SIMPLE to c tools unxutils usr share bison simple Download doxygen s source tarball and put it somewhere e g use c Nt ools Now start a new command shell and type cd Ntools gunzip dox
