It is parsed by \c doxygen. The file may contain tabs and newlines for formatting purposes. The statements in the file are case-sensitive. Comments may be placed anywhere within the file (except within quotes). Comments begin with the \# character and end at the end of the line. The file essentially consists of a list of assignment statements. Each statement consists of a \c TAG_NAME written in capitals, followed by the = character and one or more values. If the same tag is assigned more than once, the last assignment overwrites any earlier assignment. For options that take a list as their argument, the += operator can be used instead of = to append new values to the list. Values are sequences of non-blanks. If the value should contain one or more blanks it must be surrounded by quotes ("..."). Multiple lines can be concatenated by inserting a backslash (\\) as the last character of a line. Environment variables can be expanded using the pattern \$(ENV_VARIABLE_NAME). You can also include part of a configuration file from another configuration file using a \@INCLUDE tag as follows: \verbatim @INCLUDE = config_file_name \endverbatim The include file is searched in the current working directory. You can also specify a list of directories that should be searched before looking in the current working directory. Do this by putting a \@INCLUDE_PATH tag with these paths before the \@INCLUDE tag, e.g: \verbatim @INCLUDE_PATH = my_config_dir \endverbatim The configuration options can be divided into several categories. Below is an alphabetical index of the tags that are recognized followed by the descriptions of the tags grouped by category. \secreflist \refitem cfg_abbreviate_brief ABBREVIATE_BRIEF \refitem

cfg_doxyfile_encoding

\c DOXYFILE_ENCODING: \addindex DOXYFILE_ENCODING This tag specifies the encoding used for all characters in the config file that follow. The default is UTF-8 which is also the encoding used for all text before the first occurrence of this tag. Doxygen uses libiconv (or the iconv built into libc) for the transcoding. See http://www.gnu.org/software/libiconv for the list of possible encodings. \anchor cfg_project_name
\c PROJECT_NAME: \addindex PROJECT_NAME The \c PROJECT_NAME tag is a single word (or a sequence of words surrounded by double-quotes) that should identify the project for which the documentation is generated. This name is used in the title of most generated pages and in a few other places. \anchor cfg_project_number
\c PROJECT_NUMBER: \addindex PROJECT_NUMBER The \c PROJECT_NUMBER tag can be used to enter a project or revision number. This could be handy for archiving the generated documentation or if some version control system is used. \anchor cfg_output_directory
\c OUTPUT_DIRECTORY: \addindex OUTPUT_DIRECTORY The \c OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) path into which the generated documentation will be written. If a relative path is entered, it will be relative to the location where doxygen was started. If left blank the current directory will be used. \anchor cfg_create_subdirs
\c CREATE_SUBDIRS: \addindex CREATE_SUBDIRS If the \c CREATE_SUBDIRS tag is set to \c YES, then doxygen will create 4096 sub-directories (in 2 levels) under the output directory of each output format and will distribute the generated files over these directories. Enabling this option can be useful when feeding doxygen a huge amount of source files, where putting all generated files in the same directory would otherwise causes performance problems for the file system. \anchor cfg_output_language
\c OUTPUT_LANGUAGE: \addindex OUTPUT_LANGUAGE The \c OUTPUT_LANGUAGE tag is used to specify the language in which all documentation generated by doxygen is written. Doxygen will use this information to generate all constant output in the proper language. The default language is English, other supported languages are: Afrikaans, Arabic, Brazilian, Catalan, Chinese, Croatian, Czech, Danish, Dutch, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Lithuanian, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovene, Spanish, Swedish, and Ukrainian. \anchor cfg_use_windows_encoding
\c USE_WINDOWS_ENCODING: \addindex USE_WINDOWS_ENCODING This tag can be used to specify the encoding used in the generated output. The encoding is not always determined by the language that is chosen, but also whether or not the output is meant for Windows or non-Windows users. In case there is a difference, setting the \c USE_WINDOWS_ENCODING tag to \c YES forces the Windows encoding, (this is the default for the Windows binary), whereas setting the tag to \c NO uses a Unix-style encoding (the default for all platforms other than Windows). \anchor cfg_brief_member_desc
\c BRIEF_MEMBER_DESC: \addindex BRIEF_MEMBER_DESC If the \c BRIEF_MEMBER_DESC tag is set to \c YES (the default) doxygen will include brief member descriptions after the members that are listed in the file and class documentation (similar to JavaDoc). Set to NO to disable this. \anchor cfg_repeat_brief
\c REPEAT_BRIEF: \addindex REPEAT_BRIEF If the \c REPEAT_BRIEF tag is set to \c YES (the default) doxygen will prepend the brief description of a member or function before the detailed description \par Note: If both \c HIDE_UNDOC_MEMBERS and \c BRIEF_MEMBER_DESC are set to \c NO, the brief descriptions will be completely suppressed. \anchor cfg_abbreviate_brief
\c ABBREVIATE_BRIEF: \addindex ABBREVIATE_BRIEF This tag implements a quasi-intelligent brief description abbreviator that is used to form the text in various listings. Each string in this list, if found as the leading text of the brief description, will be stripped from the text and the result after processing the whole list, is used as the annotated text. Otherwise, the brief description is used as-is. If left blank, the following values are used ("\$name" is automatically replaced with the name of the entity): "The $name class" "The $name widget" "The $name file" "is" "provides" "specifies" "contains" "represents" "a" "an" "the". \anchor cfg_always_detailed_sec
\c ALWAYS_DETAILED_SEC: \addindex ALWAYS_DETAILED_SEC If the \c ALWAYS_DETAILED_SEC and \c REPEAT_BRIEF tags are both set to \c YES then doxygen will generate a detailed section even if there is only a brief description. \anchor cfg_inline_inherited_memb
\c INLINE_INHERITED_MEMB: \addindex INLINE_INHERITED_MEMB If the \c INLINE_INHERITED_MEMB tag is set to \c YES, doxygen will show all inherited members of a class in the documentation of that class as if those members were ordinary class members. Constructors, destructors and assignment operators of the base classes will not be shown. \anchor cfg_full_path_names
\c FULL_PATH_NAMES: \addindex FULL_PATH_NAMES If the \c FULL_PATH_NAMES tag is set to \c YES doxygen will prepend the full path before files name in the file list and in the header files. If set to NO the shortest path that makes the file name unique will be used \anchor cfg_strip_from_path
\c STRIP_FROM_PATH: \addindex STRIP_FROM_PATH If the \c FULL_PATH_NAMES tag is set to \c YES then the \c STRIP_FROM_PATH tag can be used to strip a user-defined part of the path. Stripping is only done if one of the specified strings matches the left-hand part of the path. The tag can be used to show relative paths in the file list. If left blank the directory from which doxygen is run is used as the path to strip. \anchor cfg_strip_from_inc_path
\c STRIP_FROM_INC_PATH: \addindex STRIP_FROM_INC_PATH The \c STRIP_FROM_INC_PATH tag can be used to strip a user-defined part of the path mentioned in the documentation of a class, which tells the reader which header file to include in order to use a class. If left blank only the name of the header file containing the class definition is used. Otherwise one should specify the include paths that are normally passed to the compiler using the -I flag. \anchor cfg_case_sense_names
\c CASE_SENSE_NAMES: \addindex CASE_SENSE_NAMES If the \c CASE_SENSE_NAMES tag is set to \c NO then doxygen will only generate file names in lower-case letters. If set to \c YES upper-case letters are also allowed. This is useful if you have classes or files whose names only differ in case and if your file system supports case sensitive file names. Windows users are advised to set this option to NO. \anchor cfg_short_names
\c SHORT_NAMES: \addindex SHORT_NAMES If the \c SHORT_NAMES tag is set to \c YES, doxygen will generate much shorter (but less readable) file names. This can be useful is your file systems doesn't support long names like on DOS, Mac, or CD-ROM. \anchor cfg_javadoc_autobrief
\c JAVADOC_AUTOBRIEF: \addindex JAVADOC_AUTOBRIEF If the \c JAVADOC_AUTOBRIEF is set to \c YES then doxygen will interpret the first line (until the first dot) of a JavaDoc-style comment as the brief description. If set to NO (the default), the Javadoc-style will behave just like regular Qt-style comments (thus requiring an explicit \@brief command for a brief description.) \anchor cfg_qt_autobrief
\c QT_AUTOBRIEF: \addindex QT_AUTOBRIEF If the \c QT_AUTOBRIEF is set to \c YES then doxygen will interpret the first line (until the first dot) of a Qt-style comment as the brief description. If set to NO (the default), the Qt-style will behave just like regular Qt-style comments (thus requiring an explicit \\brief command for a brief description.) \anchor cfg_builtin_stl_support
\c BUILTIN_STL_SUPPORT: \addindex BUILTIN_STL_SUPPORT If you use STL classes (i.e. std::string, std::vector, etc.) but do not want to include (a tag file for) the STL sources as input, then you should set this tag to \c YES in order to let doxygen match functions declarations and definitions whose arguments contain STL classes (e.g. func(std::string); v.s. func(std::string) {}). This also make the inheritance and collaboration diagrams that involve STL classes more complete and accurate. \anchor cfg_cpp_cli_support
\c CPP_CLI_SUPPORT: \addindex CPP_CLI_SUPPORT If you use Microsoft's C++/CLI language, you should set this option to YES to enable parsing support. \anchor cfg_sip_support
\c SIP_SUPPORT: \addindex OPTIMIZE_OUTPUT_SIP Set the SIP_SUPPORT tag to YES if your project consists of sip sources only. Doxygen will parse them like normal C++ but will assume all classes use public instead of private inheritance when no explicit protection keyword is present. \anchor cfg_idl_property_support
\c IDL_PROPERTY_SUPPORT: \addindex IDL_PROPERTY_SUPPORT For Microsoft's IDL there are propget and propput attributes to indicate getter and setter methods for a property. Setting this option to \c YES (the default) will make doxygen to replace the get and set methods by a property in the documentation. This will only work if the methods are indeed getting or setting a simple type. If this is not the case, or you want to show the methods anyway, you should set this option to \c NO. \anchor cfg_distribute_group_doc
\c DISTRIBUTE_GROUP_DOC: \addindex DISTRIBUTE_GROUP_DOC If member grouping is used in the documentation and the DISTRIBUTE_GROUP_DOC tag is set to YES, then doxygen will reuse the documentation of the first member in the group (if any) for the other members of the group. By default all members of a group must be documented explicitly. \anchor cfg_multiline_cpp_is_brief
\c MULTILINE_CPP_IS_BRIEF: \addindex MULTILINE_CPP_IS_BRIEF The MULTILINE_CPP_IS_BRIEF tag can be set to YES to make Doxygen treat a multi-line C++ special comment block (i.e. a block of //! or /// comments) as a brief description. This used to be the default behaviour. The new default is to treat a multi-line C++ comment block as a detailed description. Set this tag to YES if you prefer the old behaviour instead. Note that setting this tag to YES also means that rational rose comments are not recognized any more. \anchor cfg_inherit_docs
\c INHERIT_DOCS: \addindex INHERIT_DOCS If the \c INHERIT_DOCS tag is set to \c YES (the default) then an undocumented member inherits the documentation from any documented member that it re-implements. \anchor cfg_separate_member_pages
\c SEPARATE_MEMBER_PAGES: \addindex SEPARATE_MEMBER_PAGES If the \c SEPARATE_MEMBER_PAGES tag is set to \c YES, then doxygen will produce a new page for each member. If set to \c NO, the documentation of a member will be part of the file/class/namespace that contains it. \anchor cfg_tab_size
\c TAB_SIZE: \addindex TAB_SIZE the \c TAB_SIZE tag can be used to set the number of spaces in a tab. Doxygen uses this value to replace tabs by spaces in code fragments. \anchor cfg_aliases
\c ALIASES: \addindex ALIASES This tag can be used to specify a number of aliases that acts as commands in the documentation. An alias has the form \verbatim name=value \endverbatim For example adding \verbatim "sideeffect=\par Side Effects:\n" \endverbatim will allow you to put the command \\sideeffect (or \@sideeffect) in the documentation, which will result in a user-defined paragraph with heading "Side Effects:". You can put \\n's in the value part of an alias to insert newlines. \anchor cfg_optimize_output_for_c
\c OPTIMIZE_OUTPUT_FOR_C: \addindex OPTIMIZE_OUTPUT_FOR_C Set the \c OPTIMIZE_OUTPUT_FOR_C tag to \c YES if your project consists of C sources only. Doxygen will then generate output that is more tailored for C. For instance, some of the names that are used will be different. The list of all members will be omitted, etc. \anchor cfg_optimize_output_java
\c OPTIMIZE_OUTPUT_JAVA: \addindex OPTIMIZE_OUTPUT_JAVA Set the OPTIMIZE_OUTPUT_JAVA tag to YES if your project consists of Java or Python sources only. Doxygen will then generate output that is more tailored for that language. For instance, namespaces will be presented as packages, qualified scopes will look different, etc. \anchor cfg_optimize_for_fortran
\c OPTIMIZE_FOR_FORTRAN: \addindex OPTIMIZE_FOR_FORTRAN Set the \c OPTIMIZE_FOR_FORTRAN tag to \c YES if your project consists of Fortran sources. Doxygen will then generate output that is tailored for Fortran. \anchor cfg_optimize_output_vhdl
\c OPTIMIZE_OUTPUT_VHDL: \addindex OPTIMIZE_OUTPUT_VHDL Set the \c OPTIMIZE_OUTPUT_VHDL tag to \c YES if your project consists of VHDL sources. Doxygen will then generate output that is tailored for VHDL. \anchor cfg_extension_mapping
\c EXTENSION_MAPPING: \addindex EXTENSION_MAPPING Doxygen selects the parser to use depending on the extension of the files it parses. With this tag you can assign which parser to use for a given extension. Doxygen has a built-in mapping, but you can override or extend it using this tag. The format is ext=language, where ext is a file extension, and language is one of the parsers supported by doxygen: IDL, Java, Javascript, C#, C, C++, D, PHP, Objective-C, Python, Fortran, VHDL, C, C++. For instance to make doxygen treat .inc files as Fortran files (default is PHP), and .f files as C (default is Fortran), use: inc=Fortran f=C \anchor cfg_subgrouping
\c SUBGROUPING: \addindex SUBGROUPING Set the \c SUBGROUPING tag to \c YES (the default) to allow class member groups of the same type (for instance a group of public functions) to be put as a subgroup of that type (e.g. under the Public Functions section). Set it to \c NO to prevent subgrouping. Alternatively, this can be done per class using the \ref cmdnosubgrouping "\\nosubgrouping" command. \anchor cfg_typedef_hides_struct
\c TYPEDEF_HIDES_STRUCT: \addindex TYPEDEF_HIDES_STRUCT When \c TYPEDEF_HIDES_STRUCT is enabled, a typedef of a struct, union, or enum is documented as struct, union, or enum with the name of the typedef. So typedef struct TypeS {} TypeT, will appear in the documentation as a struct with name \c TypeT. When disabled the typedef will appear as a member of a file, namespace, or class. And the struct will be named \c TypeS. This can typically be useful for C code in case the coding convention dictates that all compound types are typedef'ed and only the typedef is referenced, never the tag name. \anchor cfg_symbol_cache_size
\c SYMBOL_CACHE_SIZE: \addindex SYMBOL_CACHE_SIZE The \c SYMBOL_CACHE_SIZE determines the size of the internal cache use to determine which symbols to keep in memory and which to flush to disk. When the cache is full, less often used symbols will be written to disk. For small to medium size projects (<1000 input files) the default value is probably good enough. For larger projects a too small cache size can cause doxygen to be busy swapping symbols to and from disk most of the time causing a significant performance penality. If the system has enough physical memory increasing the cache will improve the performance by keeping more symbols in memory. Note that the value works on a logarithmic scale so increasing the size by one will rougly double the memory usage. The cache size is given by this formula: \f$2^{(16+\mbox{SYMBOL\_CACHE\_SIZE})}\f$. The valid range is 0..9, the default is 0, corresponding to a cache size of \f$2^{16} = 65536\f$ symbols.

\section config_build Build related options \anchor cfg_extract_all

\c EXTRACT_ALL: \addindex EXTRACT_ALL If the \c EXTRACT_ALL tag is set to \c YES doxygen will assume all entities in documentation are documented, even if no documentation was available. Private class members and static file members will be hidden unless the \c EXTRACT_PRIVATE and \c EXTRACT_STATIC tags are set to \c YES \par Note: This will also disable the warnings about undocumented members that are normally produced when \c WARNINGS is set to \c YES \anchor cfg_extract_private
\c EXTRACT_PRIVATE: \addindex EXTRACT_PRIVATE If the \c EXTRACT_PRIVATE tag is set to \c YES all private members of a class will be included in the documentation. \anchor cfg_extract_static
\c EXTRACT_STATIC: \addindex EXTRACT_STATIC If the \c EXTRACT_STATIC tag is set to \c YES all static members of a file will be included in the documentation. \anchor cfg_extract_local_classes
\c EXTRACT_LOCAL_CLASSES: \addindex EXTRACT_LOCAL_CLASSES If the \c EXTRACT_LOCAL_CLASSES tag is set to \c 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. \anchor cfg_extract_anon_nspaces
\c EXTRACT_ANON_NSPACES: \addindex 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. \anchor cfg_extract_local_methods
\c EXTRACT_LOCAL_METHODS: \addindex EXTRACT_LOCAL_METHODS This flag is only useful for Objective-C code. When set to \c YES local methods, which are defined in the implementation section but not in the interface are included in the documentation. If set to \c NO (the default) only methods in the interface are included. \anchor cfg_hide_undoc_members
\c HIDE_UNDOC_MEMBERS: \addindex HIDE_UNDOC_MEMBERS If the \c HIDE_UNDOC_MEMBERS tag is set to \c YES, doxygen will hide all undocumented members inside documented classes or files. If set to \c NO (the default) these members will be included in the various overviews, but no documentation section is generated. This option has no effect if \c EXTRACT_ALL is enabled. \anchor cfg_hide_undoc_classes
\c HIDE_UNDOC_CLASSES: \addindex HIDE_UNDOC_CLASSES If the \c HIDE_UNDOC_CLASSESS tag is set to \c YES, doxygen will hide all undocumented classes. If set to \c NO (the default) these classes will be included in the various overviews. This option has no effect if \c EXTRACT_ALL is enabled. \anchor cfg_hide_friend_compounds

\section messages_input Options related to warning and progress messages \anchor cfg_quiet

\c QUIET: \addindex QUIET The \c QUIET tag can be used to turn on/off the messages that are generated to standard output by doxygen. Possible values are \c YES and \c NO, where \c YES implies that the messages are off. If left blank \c NO is used. \anchor cfg_warnings
\c WARNINGS: \addindex WARNINGS The \c WARNINGS tag can be used to turn on/off the warning messages that are generated to standard error by doxygen. Possible values are \c YES and \c NO, where \c YES implies that the warnings are on. If left blank \c NO is used. \b Tip: Turn warnings on while writing the documentation. \anchor cfg_warn_if_undocumented
\c WARN_IF_UNDOCUMENTED: \addindex WARN_IF_UNDOCUMENTED If \c WARN_IF_UNDOCUMENTED is set to \c YES, then doxygen will generate warnings for undocumented members. If \c EXTRACT_ALL is set to \c YES then this flag will automatically be disabled. \anchor cfg_warn_if_doc_error
\c WARN_IF_DOC_ERROR: \addindex WARN_IF_DOC_ERROR If \c WARN_IF_DOC_ERROR is set to \c YES, doxygen will generate warnings for potential errors in the documentation, such as not documenting some parameters in a documented function, or documenting parameters that don't exist or using markup commands wrongly. \anchor cfg_warn_no_paramdoc
\c WARN_NO_PARAMDOC: \addindex WARN_NO_PARAMDOC This \c WARN_NO_PARAMDOC option can be abled to get warnings for functions that are documented, but have no documentation for their parameters or return value. If set to \c NO (the default) doxygen will only warn about wrong or incomplete parameter documentation, but not about the absence of documentation. \anchor cfg_warn_format
\c WARN_FORMAT: \addindex WARN_FORMAT The \c WARN_FORMAT tag determines the format of the warning messages that doxygen can produce. The string should contain the \$file, \$line, and \$text tags, which will be replaced by the file and line number from which the warning originated and the warning text. \anchor cfg_warn_logfile
\c WARN_LOGFILE: \addindex WARN_LOGFILE The \c WARN_LOGFILE tag can be used to specify a file to which warning and error messages should be written. If left blank the output is written to stderr.

\section config_input Input related options \anchor cfg_input

\c INPUT: \addindex INPUT The \c INPUT tag is used to specify the files and/or directories that contain documented source files. You may enter file names like \c myfile.cpp or directories like \c /usr/src/myproject. Separate the files or directories with spaces.
\b Note: If this tag is empty the current directory is searched. \anchor cfg_input_encoding
\c INPUT_ENCODING: \addindex INPUT_ENCODING This tag can be used to specify the character encoding of the source files that doxygen parses. Internally doxygen uses the UTF-8 encoding, which is also the default input encoding. Doxygen uses libiconv (or the iconv built into libc) for the transcoding. See the libiconv documentation for the list of possible encodings. \anchor cfg_file_patterns
\c FILE_PATTERNS: \addindex FILE_PATTERNS If the value of the \c INPUT tag contains directories, you can use the \c FILE_PATTERNS tag to specify one or more wildcard patterns (like \c *.cpp and \c *.h ) to filter out the source-files in the directories. If left blank the following patterns are tested: *.c *.cc *.cxx *.cpp *.c++ *.java *.ii *.ixx *.ipp *.i++ *.inl *.h *.hh *.hxx *.hpp *.h++ *.idl *.odl *.cs *.php *.php3 *.inc *.m *.mm \anchor cfg_file_version_filter
\c FILE_VERSION_FILTER: \addindex FILE_VERSION_FILTER The \c FILE_VERSION_FILTER tag can be used to specify a program or script that doxygen should invoke to get the current version for each file (typically from the version control system). Doxygen will invoke the program by executing (via popen()) the command command input-file, where \c command is the value of the \c FILE_VERSION_FILTER tag, and \c input-file is the name of an input file provided by doxygen. Whatever the program writes to standard output is used as the file version. Example of using a shell script as a filter for Unix: \verbatim FILE_VERSION_FILTER = "/bin/sh versionfilter.sh" \endverbatim Example shell script for CVS: \verbatim #!/bin/sh cvs status $1 | sed -n 's/^[ \]*Working revision:[ \t]*$[0-9][0-9\.]*$.*/\1/p' \endverbatim Example shell script for Subversion: \verbatim #!/bin/sh svn stat -v $1 | sed -n 's/^[ A-Z?\*|!]\{1,15\}/r/;s/ \{1,15\}/\/r/;s/ .*//p' \endverbatim Example filter for ClearCase: \verbatim FILE_VERSION_INFO = "cleartool desc -fmt \%Vn" \endverbatim \anchor cfg_layout_file
\c LAYOUT_FILE: The \c LAYOUT_FILE tag can be used to specify a layout file which will be parsed by doxygen. The layout file controls the global structure of the generated output files in an output format independent way. The create the layout file that represents doxygen's defaults, run doxygen with the -l option. You can optionally specify a file name after the option, if omitted DoxygenLayout.xml will be used as the name of the layout file. Note that if you run doxygen from a directory containing a file called DoxygenLayout.xml, doxygen will parse it automatically even if the \c LAYOUT_FILE tag is left empty. \anchor cfg_recursive
\c RECURSIVE: \addindex RECURSIVE The \c RECURSIVE tag can be used to specify whether or not subdirectories should be searched for input files as well. Possible values are \c YES and \c NO. If left blank \c NO is used. \anchor cfg_exclude
\c EXCLUDE: \addindex EXCLUDE The \c EXCLUDE tag can be used to specify files and/or directories that should excluded from the \c INPUT source files. This way you can easily exclude a subdirectory from a directory tree whose root is specified with the \c INPUT tag. \anchor cfg_exclude_symlinks
\c EXCLUDE_SYMLINKS: \addindex EXCLUDE_SYMLINKS The \c EXCLUDE_SYMLINKS tag can be used select whether or not files or directories that are symbolic links (a Unix filesystem feature) are excluded from the input. \anchor cfg_exclude_patterns
\c EXCLUDE_PATTERNS: \addindex EXCLUDE_PATTERNS If the value of the \c INPUT tag contains directories, you can use the \c EXCLUDE_PATTERNS tag to specify one or more wildcard patterns to exclude certain files from those directories. Note that the wildcards are matched against the file with absolute path, so to exclude all test directories use the pattern */test/* \anchor cfg_example_path
\c EXAMPLE_PATH: \addindex EXAMPLE_PATH The \c EXAMPLE_PATH tag can be used to specify one or more files or directories that contain example code fragments that are included (see the \\include command in section \ref cmdinclude "\\include"). \anchor cfg_example_recursive
\c EXAMPLE_RECURSIVE: \addindex EXAMPLE_RECURSIVE If the \c EXAMPLE_RECURSIVE tag is set to \c YES then subdirectories will be searched for input files to be used with the \\include or \\dontinclude commands irrespective of the value of the \c RECURSIVE tag. Possible values are \c YES and \c NO. If left blank \c NO is used. \anchor cfg_example_patterns
\c EXAMPLE_PATTERNS: \addindex EXAMPLE_PATTERNS If the value of the \c EXAMPLE_PATH tag contains directories, you can use the \c EXAMPLE_PATTERNS tag to specify one or more wildcard pattern (like *.cpp and *.h) to filter out the source-files in the directories. If left blank all files are included. \anchor cfg_image_path
\c IMAGE_PATH: \addindex IMAGE_PATH The \c IMAGE_PATH tag can be used to specify one or more files or directories that contain images that are to be included in the documentation (see the \ref cmdimage "\\image" command). \anchor cfg_input_filter
\c INPUT_FILTER: \addindex INPUT_FILTER The \c INPUT_FILTER tag can be used to specify a program that doxygen should invoke to filter for each input file. Doxygen will invoke the filter program by executing (via popen()) the command: \verbatim \endverbatim where \ is the value of the \c INPUT_FILTER tag, and \ is the name of an input file. Doxygen will then use the output that the filter program writes to standard output. \anchor cfg_filter_patterns
\c FILTER_PATTERNS: \addindex FILTER_PATTERNS The \c FILTER_PATTERNS tag can be used to specify filters on a per file pattern basis. Doxygen will compare the file name with each pattern and apply the filter if there is a match. The filters are a list of the form: pattern=filter (like *.cpp=my_cpp_filter). See \c INPUT_FILTER for further info on how filters are used. If \c FILTER_PATTERNS is empty, \c INPUT_FILTER is applied to all files. \anchor cfg_filter_source_files
\c FILTER_SOURCE_FILES: \addindex FILTER_SOURCE_FILES If the \c FILTER_SOURCE_FILES tag is set to \c YES, the input filter (if set using \ref cfg_input_filter "INPUT_FILTER" ) will also be used to filter the input files that are used for producing the source files to browse (i.e. when SOURCE_BROWSER is set to YES).

\section sourcebrowser_index Source browsing related options \anchor cfg_source_browser

\c SOURCE_BROWSER: \addindex SOURCE_BROWSER If the \c SOURCE_BROWSER tag is set to \c YES then a list of source files will \n" be generated.

\c REFERENCES_RELATION: \addindex REFERENCES_RELATION If the \c REFERENCES_RELATION tag is set to \c YES then for each documented function all documented entities called/used by that function will be listed. \anchor cfg_references_link_source
\c REFERENCES_LINK_SOURCE: \addindex REFERENCES_LINK_SOURCE If the \c REFERENCES_LINK_SOURCE tag is set to \c YES (the default) and SOURCE_BROWSER tag is set to \c YES, then the hyperlinks from functions in REFERENCES_RELATION and REFERENCED_BY_RELATION lists will link to the source code. Otherwise they will link to the documentstion. \anchor cfg_verbatim_headers
\c VERBATIM_HEADERS: \addindex VERBATIM_HEADERS If the \c VERBATIM_HEADERS tag is set the \c YES (the default) then doxygen will generate a verbatim copy of the header file for each class for which an include is specified. Set to NO to disable this. \sa Section \ref cmdclass "\\class". \anchor cfg_use_htags
\c USE_HTAGS: \addindex USE_HTAGS If the \c USE_HTAGS tag is set to \c YES then the references to source code will point to the HTML generated by the htags(1) tool instead of doxygen built-in source browser. The htags tool is part of GNU's global source tagging system (see http://www.gnu.org/software/global/global.html). The use it do the following: -# Install the latest version of global (i.e. 4.8.6 or better) -# Enable SOURCE_BROWSER and USE_HTAGS in the config file -# Make sure the INPUT points to the root of the source tree -# Run doxygen as normal Doxygen will invoke htags (and that will in turn invoke gtags), so these tools must be available from the command line (i.e. in the search path). The result: instead of the source browser generated by doxygen, the links to source code will now point to the output of htags.

\section alphabetical_index Alphabetical index options \anchor cfg_alphabetical_index

\c ALPHABETICAL_INDEX: \addindex ALPHABETICAL_INDEX If the \c ALPHABETICAL_INDEX tag is set to \c YES, an alphabetical index of all compounds will be generated. Enable this if the project contains a lot of classes, structs, unions or interfaces.
\c COLS_IN_ALPHA_INDEX: \anchor cfg_cols_in_alpha_index \addindex COLS_IN_ALPHA_INDEX If the alphabetical index is enabled (see \c ALPHABETICAL_INDEX) then the \c COLS_IN_ALPHA_INDEX tag can be used to specify the number of columns in which this list will be split (can be a number in the range [1..20]) \anchor cfg_ignore_prefix
\c IGNORE_PREFIX: \addindex IGNORE_PREFIX In case all classes in a project start with a common prefix, all classes will be put under the same header in the alphabetical index.

\c HTML_OUTPUT: \addindex HTML_OUTPUT The \c HTML_OUTPUT tag is used to specify where the HTML docs will be put. If a relative path is entered the value of \c OUTPUT_DIRECTORY will be put in front of it. If left blank `html' will be used as the default path. \anchor cfg_html_file_extension
\c HTML_FILE_EXTENSION: \addindex HTML_FILE_EXTENSION The \c HTML_FILE_EXTENSION tag can be used to specify the file extension for each generated HTML page (for example: .htm, .php, .asp). If it is left blank doxygen will generate files with .html extension. \anchor cfg_html_header
\c HTML_HEADER: \addindex HTML_HEADER The \c HTML_HEADER tag can be used to specify a user-defined HTML header file for each generated HTML page. To get valid HTML the header file should contain at least a \c \ and a \c \ tag, but it is good idea to include the style sheet that is generated by doxygen as well. Minimal example: \verbatim My title \endverbatim If the tag is left blank doxygen will generate a standard header. The following commands have a special meaning inside the header: \$title, \$datetime, \$date, \$doxygenversion, \$projectname, and \$projectnumber. Doxygen will replace them by respectively the title of the page, the current date and time, only the current date, the version number of doxygen, the project name (see \c PROJECT_NAME), or the project number (see \c PROJECT_NUMBER). If \c CREATE_SUBDIRS is enabled, the command \$relpath\$ can be used to produce a relative path to the root of the HTML output directory, e.g. use \$relpath\$doxygen.css, to refer to the standard style sheet. See also section \ref doxygen_usage for information on how to generate the default header that doxygen normally uses. \anchor cfg_html_footer
\c HTML_FOOTER: \addindex HTML_FOOTER The \c HTML_FOOTER tag can be used to specify a user-defined HTML footer for each generated HTML page. To get valid HTML the footer file should contain at least a \c \ and a \c \ tag. A minimal example: \verbatim \endverbatim If the tag is left blank doxygen will generate a standard footer. The following commands have a special meaning inside the footer: \$title, \$datetime, \$date, \$doxygenversion, \$projectname, \$projectnumber. Doxygen will replace them by respectively the title of the page, the current date and time, only the current date, the version number of doxygen, the project name (see \c PROJECT_NAME), or the project number (see \c PROJECT_NUMBER). See also section \ref doxygen_usage for information on how to generate the default footer that doxygen normally uses. \anchor cfg_html_stylesheet
\c HTML_STYLESHEET: \addindex HTML_STYLESHEET The \c HTML_STYLESHEET tag can be used to specify a user-defined cascading style sheet that is used by each HTML page. It can be used to fine-tune the look of the HTML output. If the tag is left blank doxygen will generate a default style sheet. See also section \ref doxygen_usage for information on how to generate the style sheet that doxygen normally uses. \anchor cfg_html_align_members
\c HTML_ALIGN_MEMBERS: \addindex HTML_ALIGN_MEMBERS If the \c HTML_ALIGN_MEMBERS tag is set to \c YES, the members of classes, files or namespaces will be aligned in HTML using tables. If set to \c NO a bullet list will be used. Note: Setting this tag to \c NO will become obsolete in the future, since I only intent to support and test the aligned representation. \anchor cfg_html_dynamic_sections
\c HTML_DYNAMIC_SECTIONS: \addindex HTML_DYNAMIC_SECTIONS If the \c HTML_DYNAMIC_SECTIONS tag is set to \c YES then the generated HTML documentation will contain sections that can be hidden and shown after the page has loaded. For this to work a browser that supports JavaScript and DHTML is required (for instance Mozilla 1.0+, Firefox Netscape 6.0+, Internet explorer 5.0+, Konqueror, or Safari). \anchor cfg_generate_docset
\c GENERATE_DOCSET: \addindex GENERATE_DOCSET If the \c GENERATE_DOCSET tag is set to \c YES, additional index files will be generated that can be used as input for Apple's Xcode 3 integrated development environment, introduced with OSX 10.5 (Leopard). To create a documentation set, doxygen will generate a Makefile in the HTML output directory. Running \c make will produce the docset in that directory and running make install will install the docset in ~/Library/Developer/Shared/Documentation/DocSets so that Xcode will find it at startup. See this article for more information. \anchor cfg_docset_feedname
\c DOCSET_FEEDNAME: \addindex DOCSET_FEEDNAME When \c GENERATE_DOCSET tag is set to \c YES, this tag determines the name of the feed. A documentation feed provides an umbrella under which multiple documentation sets from a single provider (such as a company or product suite) can be grouped. \anchor cfg_docset_bundle_id
\c DOCSET_BUNDLE_ID: When \c GENERATE_DOCSET tag is set to \c YES, this tag specifies a string that should uniquely identify the documentation set bundle. This should be a reverse domain-name style string, e.g. com.mycompany.MyDocSet. Doxygen will append .docset to the name. \anchor cfg_generate_htmlhelp
\c GENERATE_HTMLHELP: \addindex GENERATE_HTMLHELP If the \c GENERATE_HTMLHELP tag is set to \c YES then doxygen generates three additional HTML index files: \c index.hhp, \c index.hhc, and \c index.hhk. The \c index.hhp is a project file that can be read by Microsoft's HTML Help Workshop on Windows. The HTML Help Workshop contains a compiler that can convert all HTML output generated by doxygen into a single compiled HTML file (.chm). Compiled HTML files are now used as the Windows 98 help format, and will replace the old Windows help format (.hlp) on all Windows platforms in the future. Compressed HTML files also contain an index, a table of contents, and you can search for words in the documentation. The HTML workshop also contains a viewer for compressed HTML files. \anchor cfg_chm_file
\c CHM_FILE: \addindex CHM_FILE If the \c GENERATE_HTMLHELP tag is set to \c YES, the \c CHM_FILE tag can be used to specify the file name of the resulting .chm file. You can add a path in front of the file if the result should not be written to the html output directory. \anchor cfg_hhc_location
\c HHC_LOCATION: \addindex HHC_LOCATION If the \c GENERATE_HTMLHELP tag is set to \c YES, the \c HHC_LOCATION tag can be used to specify the location (absolute path including file name) of the HTML help compiler (hhc.exe). If non-empty doxygen will try to run the HTML help compiler on the generated index.hhp. \anchor cfg_generate_chi
\c GENERATE_CHI: \addindex GENERATE_CHI If the \c GENERATE_HTMLHELP tag is set to \c YES, the \c GENERATE_CHI flag controls if a separate .chi index file is generated (YES) or that it should be included in the master .chm file (NO). \anchor cfg_binary_toc
\c BINARY_TOC: \addindex BINARY_TOC If the \c GENERATE_HTMLHELP tag is set to \c YES, the \c BINARY_TOC flag controls whether a binary table of contents is generated (YES) or a normal table of contents (NO) in the .chm file. \anchor cfg_toc_expand
\c TOC_EXPAND: \addindex TOC_EXPAND The \c TOC_EXPAND flag can be set to YES to add extra items for group members to the table of contents of the HTML help documentation and to the tree view. \anchor cfg_generate_qhp
\c GENERATE_QHP: \addindex GENERATE_QHP If the GENERATE_QHP tag is set to YES and both QHP_NAMESPACE and QHP_VIRTUAL_FOLDER are set, an additional index file will be generated that can be used as input for Qt's qhelpgenerator to generate a Qt Compressed Help (.qch) of the generated HTML documentation. \anchor cfg_qhp_namespace

\c QHP_CUST_FILTER_NAME: \addindex QHP_CUST_FILTER_NAME If QHP_CUST_FILTER_NAME is set, it specifies the name of a custom filter to add. For more information please see Qt Help Project / Custom Filters. \anchor cfg_qhp_cust_filter_attrs
\c QHP_CUST_FILTER_ATTRS: \addindex QHP_CUST_FILTER_ATTRS The QHP_CUST_FILTER_ATTRIBUTES tag specifies the list of the attributes of the custom filter to add. For more information please see Qt Help Project / Custom Filters. \anchor cfg_qhp_sect_filter_attrs
\c QHP_SECT_FILTER_ATTRS: \addindex QHP_SECT_FILTER_ATTRS The QHP_SECT_FILTER_ATTRS tag specifies the list of the attributes this project's filter section matches. Qt Help Project / Filter Attributes. \anchor cfg_qhg_location
\c QHG_LOCATION: \addindex QHG_LOCATION If the GENERATE_QHP tag is set to YES, the QHG_LOCATION tag can be used to specify the location of Qt's qhelpgenerator. If non-empty doxygen will try to run qhelpgenerator on the generated .qhp file. \anchor cfg_disable_index
\c DISABLE_INDEX: \addindex DISABLE_INDEX If you want full control over the layout of the generated HTML pages it might be necessary to disable the index and replace it with your own. The \c DISABLE_INDEX tag can be used to turn on/off the condensed index at top of each page. A value of NO (the default) enables the index and the value YES disables it. \anchor cfg_enum_values_per_line
\c ENUM_VALUES_PER_LINE: \addindex ENUM_VALUES_PER_LINE This tag can be used to set the number of enum values (range [1..20]) that doxygen will group on one line in the generated HTML documentation. \anchor cfg_generate_treeview
\c GENERATE_TREEVIEW: \addindex GENERATE_TREEVIEW The GENERATE_TREEVIEW tag is used to specify whether a tree-like index structure should be generated to display hierarchical information. If the tag value is set to FRAME, a side panel will be generated containing a tree-like index structure (just like the one that is generated for HTML Help). For this to work a browser that supports JavaScript, DHTML, CSS and frames is required (for instance Mozilla 1.0+, Netscape 6.0+, Internet explorer 5.0+, or Konqueror). Windows users are probably better off using the HTML help feature. Other possible values for this tag are: \c HIERARCHIES, which will generate the Groups, Directories, and Class Hierarchy pages using a tree view instead of an ordered list; ALL, which combines the behavior of \c FRAME and \c HIERARCHIES, and \c NONE, which disables this behavior completely. For backwards compatibility with previous releases of Doxygen, the values YES and NO are equivalent to FRAME and NONE respectively. Via custom stylesheets (see \ref cfg_html_stylesheet "HTML_STYLESHEET") one can further \ref doxygen_finetune "fine tune" the look of the index. As an example, the default style sheet generated by doxygen has an example that shows how to put an image at the root of the tree instead of the \ref cfg_project_name "project name". \anchor cfg_treeview_width
\c TREEVIEW_WIDTH: \addindex TREEVIEW_WIDTH If the treeview is enabled (see \c GENERATE_TREEVIEW) then this tag can be used to set the initial width (in pixels) of the frame in which the tree is shown. \anchor cfg_formula_fontsize
\c FORMULA_FONTSIZE: \addindex FORMULA_FONTSIZE Use this tag to change the font size of Latex formulas included as images in the HTML documentation. The default is 10. when you change the font size after a successful doxygen run you need to manually remove any form_*.png images from the HTML output directory to force them to be regenerated.

If left blank a4wide will be used. \anchor cfg_extra_packages

\c EXTRA_PACKAGES

\addindex EXTRA_PACKAGES The \c EXTRA_PACKAGES tag can be used to specify one or more \f$\mbox{\LaTeX}\f$ package names that should be included in the \f$\mbox{\LaTeX}\f$ output. To get the times font for instance you can specify \verbatim EXTRA_PACKAGES = times \endverbatim If left blank no extra packages will be included. \anchor cfg_latex_header

\c LATEX_HEADER

\addindex LATEX_HEADER The \c LATEX_HEADER tag can be used to specify a personal \f$\mbox{\LaTeX}\f$ header for the generated \f$\mbox{\LaTeX}\f$ document. The header should contain everything until the first chapter. If it is left blank doxygen will generate a standard header. See section \ref doxygen_usage for information on how to let doxygen write the default header to a separate file. \par Note: Only use a user-defined header if you know what you are doing! The following commands have a special meaning inside the header: \$title, \$datetime, \$date, \$doxygenversion, \$projectname, \$projectnumber. Doxygen will replace them by respectively the title of the page, the current date and time, only the current date, the version number of doxygen, the project name (see \c PROJECT_NAME), or the project number (see \c PROJECT_NUMBER). \anchor cfg_pdf_hyperlinks

\c PDF_HYPERLINKS

\addindex PDF_HYPERLINKS If the \c PDF_HYPERLINKS tag is set to \c YES, the \f$\mbox{\LaTeX}\f$ that is generated is prepared for conversion to PDF (using ps2pdf or pdflatex).

\c LATEX_BATCHMODE

\addindex LATEX_BATCHMODE If the \c LATEX_BATCHMODE tag is set to \c YES, doxygen will add the \\batchmode. command to the generated \f$\mbox{\LaTeX}\f$ files. This will instruct \f$\mbox{\LaTeX}\f$ to keep running if errors occur, instead of asking the user for help. This option is also used when generating formulas in HTML. \anchor cfg_latex_hide_indices

\c LATEX_HIDE_INDICES

\addindex LATEX_HIDE_INDICES If \c LATEX_HIDE_INDICES is set to \c YES then doxygen will not include the index chapters (such as File Index, Compound Index, etc.) in the output.

\c RTF_HYPERLINKS: \addindex RTF_HYPERLINKS If the \c RTF_HYPERLINKS tag is set to \c YES, the RTF that is generated will contain hyperlink fields. The RTF file will contain links (just like the HTML output) instead of page references. This makes the output suitable for online browsing using Word or some other Word compatible reader that support those fields. \par note: WordPad (write) and others do not support links. \anchor cfg_rtf_stylesheet_file
\c RTF_STYLESHEET_FILE: \addindex RTF_STYLESHEET_FILE Load stylesheet definitions from file. Syntax is similar to doxygen's config file, i.e. a series of assignments. You only have to provide replacements, missing definitions are set to their default value. See also section \ref doxygen_usage for information on how to generate the default style sheet that doxygen normally uses. \anchor cfg_rtf_extensions_file
\c RTF_EXTENSIONS_FILE: Set optional variables used in the generation of an RTF document. Syntax is similar to doxygen's config file. A template extensions file can be generated using doxygen -e rtf extensionFile.

\section man_output Man page related options \anchor cfg_generate_man

\c GENERATE_MAN: \addindex GENERATE_MAN If the \c GENERATE_MAN tag is set to \c YES (the default) doxygen will generate man pages for classes and files. \anchor cfg_man_output
\c MAN_OUTPUT: \addindex MAN_OUTPUT The \c MAN_OUTPUT tag is used to specify where the man pages will be put. If a relative path is entered the value of \c OUTPUT_DIRECTORY will be put in front of it. If left blank `man' will be used as the default path. A directory man3 will be created inside the directory specified by \c MAN_OUTPUT. \anchor cfg_man_extension
\c MAN_EXTENSION: \addindex MAX_EXTENSION The \c MAN_EXTENSION tag determines the extension that is added to the generated man pages (default is the subroutine's section .3) \anchor cfg_man_links
\c MAN_LINKS: \addindex MAN_LINKS If the \c MAN_LINKS tag is set to \c YES and doxygen generates man output, then it will generate one additional man file for each entity documented in the real man page(s). These additional files only source the real man page, but without them the man command would be unable to find the correct page. The default is \c NO.

\section xml_output XML related options \anchor cfg_generate_xml

\c GENERATE_XML: \addindex GENERATE_XML If the \c GENERATE_XML tag is set to \c YES Doxygen will generate an XML file that captures the structure of the code including all documentation. \anchor cfg_xml_output
\c XML_OUTPUT: \addindex XML_OUTPUT The \c XML_OUTPUT tag is used to specify where the XML pages will be put. If a relative path is entered the value of \c OUTPUT_DIRECTORY will be put in front of it. If left blank \c xml will be used as the default path. \anchor cfg_xml_schema

\c XML_PROGRAMLISTING: \addindex XML_PROGRAMLISTING If the \c XML_PROGRAMLISTING tag is set to \c YES Doxygen will dump the program listings (including syntax highlighting and cross-referencing information) to the XML output. Note that enabling this will significantly increase the size of the XML output.

\section autogen_output AUTOGEN_DEF related options \anchor cfg_generate_autogen_def

\c GENERATE_AUTOGEN_DEF: \addindex GENERATE_AUTOGEN_DEF If the \c GENERATE_AUTOGEN_DEF tag is set to \c YES Doxygen will generate an AutoGen Definitions (see http://autogen.sf.net) file that captures the structure of the code including all documentation. Note that this feature is still experimental and incomplete at the moment.

\section perlmod_output PERLMOD related options \anchor cfg_generate_perlmod

\c GENERATE_PERLMOD: \addindex GENERATE_PERLMOD If the \c GENERATE_PERLMOD tag is set to \c YES Doxygen will generate a Perl module file that captures the structure of the code including all documentation. Note that this feature is still experimental and incomplete at the moment. \anchor cfg_perlmod_latex
\c PERLMOD_LATEX: \addindex PERLMOD_LATEX If the \c PERLMOD_LATEX tag is set to \c YES Doxygen will generate the necessary Makefile rules, Perl scripts and LaTeX code to be able to generate PDF and DVI output from the Perl module output. \anchor cfg_perlmod_pretty
\c PERLMOD_PRETTY: \addindex PERLMOD_PRETTY If the \c PERLMOD_PRETTY tag is set to \c YES the Perl module output will be nicely formatted so it can be parsed by a human reader. This is useful if you want to understand what is going on. On the other hand, if this tag is set to \c NO the size of the Perl module output will be much smaller and Perl will parse it just the same. \anchor cfg_perlmod_makevar_prefix
\c PERLMOD_MAKEVAR_PREFIX: \addindex PERLMOD_MAKEVAR_PREFIX The names of the make variables in the generated doxyrules.make file are prefixed with the string contained in \c PERLMOD_MAKEVAR_PREFIX. This is useful so different doxyrules.make files included by the same Makefile don't overwrite each other's variables.

\section config_prepro Preprocessor related options \anchor cfg_enable_preprocessing

\c ENABLE_PREPROCESSING: \addindex ENABLE_PREPROCESSING If the \c ENABLE_PREPROCESSING tag is set to \c YES (the default) doxygen will evaluate all C-preprocessor directives found in the sources and include files. \anchor cfg_macro_expansion
\c MACRO_EXPANSION: \addindex MACRO_EXPANSION If the \c MACRO_EXPANSION tag is set to \c YES doxygen will expand all macro names in the source code. If set to \c NO (the default) only conditional compilation will be performed. Macro expansion can be done in a controlled way by setting \c EXPAND_ONLY_PREDEF to \c YES. \anchor cfg_expand_only_predef
\c EXPAND_ONLY_PREDEF: \addindex EXPAND_ONLY_PREDEF If the \c EXPAND_ONLY_PREDEF and \c MACRO_EXPANSION tags are both set to YES then the macro expansion is limited to the macros specified with the \c PREDEFINED and \c EXPAND_AS_DEFINED tags. \anchor cfg_search_includes

\c PREDEFINED: \addindex PREDEFINED The \c PREDEFINED tag can be used to specify one or more macro names that are defined before the preprocessor is started (similar to the -D option of gcc). The argument of the tag is a list of macros of the form: name or name=definition (no spaces). If the definition and the "=" are omitted, "=1" is assumed. To prevent a macro definition from being undefined via \#undef or recursively expanded use the := operator instead of the = operator. \anchor cfg_expand_as_defined
\c EXPAND_AS_DEFINED: \addindex EXPAND_AS_DEFINED If the \c MACRO_EXPANSION and \c EXPAND_ONLY_PREDEF tags are set to \c YES then this tag can be used to specify a list of macro names that should be expanded. The macro definition that is found in the sources will be used. Use the \c PREDEFINED tag if you want to use a different macro definition. \anchor cfg_skip_function_macros
\c SKIP_FUNCTION_MACROS: \addindex SKIP_FUNCTION_MACROS If the \c SKIP_FUNCTION_MACROS tag is set to \c YES (the default) then doxygen's preprocessor will remove all function-like macros that are alone on a line, have an all uppercase name, and do not end with a semicolon. Such function macros are typically used for boiler-plate code, and will confuse the parser if not removed.

\section config_extref External reference options \anchor cfg_tagfiles

\c TAGFILES

\addindex TAGFILES The \c TAGFILES tag can be used to specify one or more tagfiles. See section \ref doxytag_usage for more information about the usage of tag files. Optionally an initial location of the external documentation can be added for each tagfile. The format of a tag file without this location is as follows:

TAGFILES = file1 file2 ...

Adding location for the tag files is done as follows:

TAGFILES = file1=loc1 "file2 = loc2" ...

where \c loc1 and \c loc2 can be relative or absolute paths or URLs, If a location is present for each tag, the installdox tool (see section \ref installdox_usage for more information) does not have to be run to correct the links. \par Note: Each tag file must have a unique name (where the name does \e not include the path) If a tag file is not located in the directory in which doxygen is run, you must also specify the path to the tagfile here. \anchor cfg_generate_tagfile

\c GENERATE_TAGFILE

\addindex GENERATE_TAGFILE When a file name is specified after \c GENERATE_TAGFILE, doxygen will create a tag file that is based on the input files it reads. See section \ref doxytag_usage for more information about the usage of tag files. \anchor cfg_allexternals

\section config_dot Dot options \anchor cfg_class_diagrams

\c CLASS_DIAGRAMS: \addindex CLASS_DIAGRAMS If the \c CLASS_DIAGRAMS tag is set to \c YES (the default) doxygen will generate a class diagram (in HTML and \f$\mbox{\LaTeX}\f$) for classes with base or super classes. Setting the tag to \c NO turns the diagrams off. Note that this option is superseded by the HAVE_DOT option below. This is only a fallback. It is recommended to install and use dot, since it yields more powerful graphs. \anchor cfg_mscgen_path
\c MSCGEN_PATH: \addindex MSCGEN_PATH You can define message sequence charts within doxygen comments using the \ref cmdmsc "\\msc" command. Doxygen will then run the msgen tool) to produce the chart and insert it in the documentation. The MSCGEN_PATH tag allows you to specify the directory where the mscgen tool resides. If left empty the tool is assumed to be found in the default search path. \anchor cfg_have_dot
\c HAVE_DOT: \addindex HAVE_DOT If you set the \c HAVE_DOT tag to \c YES then doxygen will assume the dot tool is available from the path. This tool is part of Graphviz, a graph visualization toolkit from AT\&T and Lucent Bell Labs. The other options in this section have no effect if this option is set to \c NO (the default) \anchor cfg_dot_fontname
\c DOT_FONTNAME: \addindex DOT_FONTNAME By default doxygen will write a font called \c FreeSans.ttf to the output directory and reference it in all dot files that doxygen generates. This font does not include all possible unicode characters however, so when you need these (or just want a differently looking font) you can specify the font name using \c DOT_FONTNAME. You need need to make sure dot is able to find the font, which can be done by putting it in a standard location or by setting the \c DOTFONTPATH environment variable or by setting \c DOT_FONTPATH to the directory containing the font. \anchor cfg_dot_fontsize
\c DOT_FONTSIZE: The \c DOT_FONTSIZE tag can be used to set the size of the font of dot graphs. The default size is 10pt. \anchor cfg_dot_fontpath
\c DOT_FONTPATH: \addindex DOT_FONTPATH By default doxygen will tell dot to use the output directory to look for the \c FreeSans.ttf font (which doxygen will put there itself). If you specify a different font using \c DOT_FONTNAME you can set the path where dot can find it using this tag.
\c DOT_FONTNAME: \addindex DOT_FONTNAME By default doxygen will write a font called FreeSans.ttf to the output directory and reference it in all dot files that doxygen generates. This font does not include all possible unicode characters however, so when you need these (or just want a differently looking font) you can specify the font name using \c DOT_FONTNAME. You need need to make sure dot is able to find the font, which can be done by putting it in a standard location or by setting the \c DOTFONTPATH environment variable or by setting \c DOT_FONTPATH to the directory containing the font.
\c DOT_FONTPATH: \addindex DOT_FONTPATH By default doxygen will tell dot to use the output directory to look for the FreeSans.ttf font (which doxygen will put there itself).

\c CLASS_GRAPH: \addindex CLASS_GRAPH If the \c CLASS_GRAPH and \c HAVE_DOT tags are set to \c YES then doxygen will generate a graph for each documented class showing the direct and indirect inheritance relations. Setting this tag to \c YES will force the the \c CLASS_DIAGRAMS tag to NO. \anchor cfg_collaboration_graph
\c COLLABORATION_GRAPH: \addindex COLLABORATION_GRAPH If the \c COLLABORATION_GRAPH and \c HAVE_DOT tags are set to \c YES then doxygen will generate a graph for each documented class showing the direct and indirect implementation dependencies (inheritance, containment, and class references variables) of the class with other documented classes. \anchor cfg_group_graphs
\c GROUP_GRAPHS: \addindex GROUP_GRAPHS If the GROUP_GRAPHS and HAVE_DOT tags are set to YES then doxygen will generate a graph for groups, showing the direct groups dependencies. \anchor cfg_uml_look

\c HIDE_UNDOC_RELATIONS: \addindex HIDE_UNDOC_RELATIONS If set to YES, the inheritance and collaboration graphs will hide inheritance and usage relations if the target is undocumented or is not a class. \anchor cfg_include_graph
\c INCLUDE_GRAPH: \addindex INCLUDE_GRAPH If the \c ENABLE_PREPROCESSING, \c SEARCH_INCLUDES, \c INCLUDE_GRAPH, and \c HAVE_DOT tags are set to \c YES then doxygen will generate a graph for each documented file showing the direct and indirect include dependencies of the file with other documented files. \anchor cfg_included_by_graph
\c INCLUDED_BY_GRAPH: \addindex INCLUDED_BY_GRAPH If the \c ENABLE_PREPROCESSING, \c SEARCH_INCLUDES, \c INCLUDED_BY_GRAPH, and \c HAVE_DOT tags are set to \c YES then doxygen will generate a graph for each documented header file showing the documented files that directly or indirectly include this file. \anchor cfg_call_graph
\c CALL_GRAPH: \addindex CALL_GRAPH If the \c CALL_GRAPH and \c HAVE_DOT tags are set to \c YES then doxygen will generate a call dependency graph for every global function or class method. Note that enabling this option will significantly increase the time of a run. So in most cases it will be better to enable call graphs for selected functions only using the \\callgraph command. \anchor cfg_caller_graph
\c CALLER_GRAPH: \addindex CALLER_GRAPH If the \c CALLER_GRAPH and \c HAVE_DOT tags are set to \c YES then doxygen will generate a caller dependency graph for every global function or class method. Note that enabling this option will significantly increase the time of a run. So in most cases it will be better to enable caller graphs for selected functions only using the \\callergraph command. \anchor cfg_graphical_hierarchy

\c DIRECTORY_GRAPH: \addindex DIRECTORY_GRAPH If the \c DIRECTORY_GRAPH, \c SHOW_DIRECTORIES and \c HAVE_DOT options are set to \c YES then doxygen will show the dependencies a directory has on other directories in a graphical way. The dependency relations are determined by the \#include relations between the files in the directories. \anchor cfg_dot_graph_max_nodes
\c DOT_GRAPH_MAX_NODES: \addindex DOT_GRAPH_MAX_NODES The \c DOT_GRAPH_MAX_NODES tag can be used to set the maximum number of nodes that will be shown in the graph. If the number of nodes in a graph becomes larger than this value, doxygen will truncate the graph, which is visualized by representing a node as a red box. Note that doxygen if the number of direct children of the root node in a graph is already larger than \c DOT_GRAPH_MAX_NODES then the graph will not be shown at all. Also note that the size of a graph can be further restricted by \c MAX_DOT_GRAPH_DEPTH. \anchor cfg_max_dot_graph_depth
\c MAX_DOT_GRAPH_DEPTH: \addindex MAX_DOT_GRAPH_DEPTH The \c MAX_DOT_GRAPH_DEPTH tag can be used to set the maximum depth of the graphs generated by dot. A depth value of 3 means that only nodes reachable from the root by following a path via at most 3 edges will be shown. Nodes that lay further from the root node will be omitted. Note that setting this option to 1 or 2 may greatly reduce the computation time needed for large code bases. Also note that the size of a graph can be further restricted by \c DOT_GRAPH_MAX_NODES. Using a depth of 0 means no depth restriction (the default). \anchor cfg_dot_image_format
\c DOT_IMAGE_FORMAT: \addindex DOT_IMAGE_FORMAT The \c DOT_IMAGE_FORMAT tag can be used to set the image format of the images generated by dot. Possible values are gif, jpg, and png. If left blank png will be used. \anchor cfg_dot_path

\c DOTFILE_DIRS: \addindex DOTFILE_DIRS This tag can be used to specify one or more directories that contain dot files that are included in the documentation (see the \\dotfile command). \anchor cfg_dot_transparent
\c DOT_TRANSPARENT: \addindex DOT_TRANSPARENT Set the \c DOT_TRANSPARENT tag to \c YES to generate images with a transparent background. This is disabled by default, because dot on Windows does not seem to support this out of the box. Warning: Depending on the platform used, enabling this option may lead to badly anti-aliased labels on the edges of a graph (i.e. they become hard to read). \anchor cfg_dot_multi_targets
\c DOT_MULTI_TARGETS: \addindex DOT_MULTI_TARGET Set the \c DOT_MULTI_TARGETS tag to \c YES allow dot to generate multiple output files in one run (i.e. multiple -o and -T options on the command line). This makes dot run faster, but since only newer versions of dot (>1.8.10) support this, this feature is disabled by default. \anchor cfg_generate_legend
\c GENERATE_LEGEND: \addindex GENERATE_LEGEND If the \c GENERATE_LEGEND tag is set to \c YES (the default) doxygen will generate a legend page explaining the meaning of the various boxes and arrows in the dot generated graphs. \anchor cfg_dot_cleanup

\section config_search Search engine options \anchor cfg_searchengine

\c SEARCHENGINE: \addindex SEARCHENGINE The \c SEARCHENGINE tag specifies whether or not the HTML output should contain a search facility. Possible values are \c YES and \c NO. If set to YES, doxygen will produce a search index and a PHP script to search through the index. For this to work the documentation should be viewed via a web-server running PHP version 4.1.0 or higher. (See http://www.php.net/manual/en/installation.php for installation instructions).
