\section config_format Format

A configuration file is a free-form ASCII text file with a structure
that is similar to that of a \c Makefile, with the default name \c Doxyfile. 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 beginning with two hash characters (\c \#\#) are kept when updating
the configuration file and are placed in front of the TAG they are in front of.
Comments beginning with two hash characters (\c \#\#) at the beginning of the
configuration file are also kept and placed at the beginning of the file.
Comments beginning with two hash characters (\c \#\#) at the end of the
configuration file are also kept and placed at the end of the file.
Comments begin with the hash character (\c \#) and ends 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 equal sign (<code>=</code>) and one or more values. If the same tag
is assigned more than once, the last assignment overwrites any earlier
assignment. For tags that take a list as their argument,
the <code>+=</code> operator can be used instead of <code>=</code> 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 (<code>&quot;...&quot;</code>).
Multiple lines can be concatenated by inserting a backslash (\c \\)
as the last character of a line. Environment variables can be expanded
using the pattern <code>\$(ENV_VARIABLE_NAME)</code>.

You can also include part of a configuration file from another configuration
file using a <code>\@INCLUDE</code> 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 <code>\@INCLUDE_PATH</code> tag
with these paths before the <code>\@INCLUDE</code> 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.

      <![CDATA[
This file describes the settings to be used by the documentation system
doxygen (www.doxygen.org) for a project.
<br>
All text after a double hash (##) is considered a comment and is placed
in front of the TAG it is preceding.<br>
All text after a single hash (#) is considered a comment and will be ignored.
The format is:
\verbatim
      TAG = value [value, ...]
\endverbatim
For lists, items can also be appended using:
\verbatim
      TAG += value [value, ...]
\endverbatim
Values that contain spaces should be placed between quotes (\" \").

\section config_examples Examples

Suppose you have a simple project consisting of two files: a source file
\c example.cc and a header file \c example.h.
Then a minimal configuration file is as simple as:
\verbatim
INPUT            = example.cc example.h
\endverbatim

Assuming the example makes use of Qt classes and \c perl is located
in <code>/usr/bin</code>, a more realistic configuration file would be:
\verbatim
PROJECT_NAME     = Example
INPUT            = example.cc example.h
WARNINGS         = YES
TAGFILES         = qt.tag
SEARCHENGINE     = NO
\endverbatim

To generate the documentation for the
<a href="https://sourceforge.net/projects/qdbttabular/">QdbtTabular</a> package
I have used the following configuration file:
\verbatim
PROJECT_NAME     = QdbtTabular
OUTPUT_DIRECTORY = html
WARNINGS         = YES
INPUT            = examples/examples.doc src
FILE_PATTERNS    = *.cc *.h
INCLUDE_PATH     = examples
TAGFILES         = qt.tag
SEARCHENGINE     = YES
\endverbatim

To regenerate the Qt-1.44 documentation from the sources, you could use the
following configuration file:
\verbatim
PROJECT_NAME         = Qt
OUTPUT_DIRECTORY     = qt_docs
HIDE_UNDOC_MEMBERS   = YES
HIDE_UNDOC_CLASSES   = YES
ENABLE_PREPROCESSING = YES
MACRO_EXPANSION      = YES

                       QIntDictIteratorT:=QIntDictIterator \
                       QPtrDictIteratorT:=QPtrDictIterator

FILE_PATTERNS        = *.cpp *.h q*.doc
INCLUDE_PATH         = $(QTDIR)/include
RECURSIVE            = YES
\endverbatim

For the Qt-2.1 sources I recommend to use the following settings:
\verbatim
PROJECT_NAME          = Qt
PROJECT_NUMBER        = 2.1
HIDE_UNDOC_MEMBERS    = YES
HIDE_UNDOC_CLASSES    = YES

FILE_PATTERNS         = *.cpp *.h q*.doc
RECURSIVE             = YES
EXCLUDE_PATTERNS      = *codec.cpp moc_* */compat/* */3rdparty/*
ALPHABETICAL_INDEX    = YES
IGNORE_PREFIX         = Q
ENABLE_PREPROCESSING  = YES
MACRO_EXPANSION       = YES
INCLUDE_PATH          = $(QTDIR)/include
PREDEFINED            = Q_PROPERTY(x)= \
                        Q_OVERRIDE(x)= \
                        Q_EXPORT= \
                        Q_ENUMS(x)= \
                        "QT_STATIC_CONST=static const " \
                        _WS_X11_ \
                        INCLUDE_MENUITEM_DEF
EXPAND_ONLY_PREDEF    = YES
EXPAND_AS_DEFINED     = Q_OBJECT_FAKE Q_OBJECT ACTIVATE_SIGNAL_WITH_PARAM \
                        Q_VARIANT_AS
\endverbatim

Here doxygen's preprocessor is used to substitute some
macro names that are normally substituted by the C preprocessor,
but without doing full macro expansion.

<![CDATA[
 This tag specifies the encoding used for all characters in the configuration 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 \c libiconv (or the iconv built into
 \c libc) for the transcoding. See https://www.gnu.org/software/libiconv/ for the list of
 possible encodings.

<![CDATA[
 With the \c PROJECT_LOGO tag one can specify a logo or an icon that is
 included in the documentation. The maximum height of the logo should not
 exceed 55 pixels and the maximum width should not exceed 200 pixels.
 Doxygen will copy the logo to the output directory.

    <option type='string' id='OUTPUT_DIRECTORY' format='dir' defval=''>
      <docs>
<![CDATA[
 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.

    <option type='bool' id='CREATE_SUBDIRS' defval='0'>
      <docs>
<![CDATA[
 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.

<![CDATA[
 If the \c ALLOW_UNICODE_NAMES tag is set to \c YES,
 doxygen will allow non-ASCII characters to appear in the names of generated files.
 If set to \c NO, non-ASCII characters will be escaped, for example _xE3_x81_x84
 will be used for Unicode U+3044.

 For example adding
\verbatim
 "sideeffect=@par Side Effects:^^"

 will allow you to
 put the command \c \\sideeffect (or \c \@sideeffect) in the documentation, which
 will result in a user-defined paragraph with heading "Side Effects:".
 Note that you cannot put \ref cmdn "\\n"'s in the value part of an alias to insert newlines
 (in the resulting output).
 You can put `^^` in the value part of an alias to insert a newline as if
 a physical newline was in the original file.

 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 <code>ext=language</code>, where \c ext is a file extension, and language is one of
 the parsers supported by doxygen: IDL, Java, JavaScript, Csharp (C#), C, C++, Lex, D, PHP,
 md (Markdown), Objective-C, Python, Slice, VHDL, Fortran (fixed format Fortran: FortranFixed,
 free formatted Fortran: FortranFree, unknown formatted Fortran: Fortran. In
 the later case the parser tries to guess whether the code is fixed or free
 formatted code, this is the default for Fortran type files).

 For instance to make doxygen treat
 <code>.inc</code> files as Fortran files (default is PHP), and <code>.f</code> files as C (default is Fortran),
 use: `inc=Fortran f=C`.

 <br>Note: For files without extension you can use `no_extension` as a placeholder.
 <br>Note that for custom extensions you also need to set \ref cfg_file_patterns "FILE_PATTERNS" otherwise the
 files are not read by doxygen. When specifying `no_extension` you should add `*`
 to the \ref cfg_file_patterns "FILE_PATTERNS".

 The size of the symbol lookup cache can be
 set using \c LOOKUP_CACHE_SIZE. This cache is used to resolve symbols given
 their name and scope. Since this can be an expensive process and often the
 same symbol appears multiple times in the code, doxygen keeps a cache of
 pre-resolved symbols. If the cache is too small doxygen will become slower.
 If the cache is too large, memory is wasted. The cache size is given by this
 formula: \f$2^{(16+\mbox{LOOKUP\_CACHE\_SIZE})}\f$. The valid range is 0..9, the default is 0,
 corresponding to a cache size of \f$2^{16} = 65536\f$ symbols.
 At the end of a run doxygen will report the cache usage and suggest the
 optimal cache size from a speed point of view.

 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

 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.

 -# Make sure the \ref cfg_input "INPUT" points to the root of the source tree

 The \c HTML_HEADER tag can be used to specify a user-defined HTML
 header file for each generated HTML page.
 If the tag is left blank doxygen will generate a
 standard header.
<br>
 To get valid HTML the header file that
 includes any scripts and style sheets that doxygen
 needs, which is dependent on the configuration options used (e.g. the
 setting \ref cfg_generate_treeview "GENERATE_TREEVIEW").
 It is highly recommended to start with a default header using
\verbatim
doxygen -w html new_header.html new_footer.html new_stylesheet.css YourConfigFile
\endverbatim
 and then modify the file \c new_header.html.

 See also section \ref doxygen_usage for information on how to generate
 the default header that doxygen normally uses.

 @note The header is subject to change so you typically
 have to regenerate the default header when upgrading to a newer version of
 doxygen.

 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 (tabs) at
 top of each HTML page. A value of \c NO enables the index and the
 value \c YES disables it. Since the tabs in the index contain the same
 information as the navigation tree, you can set this option to \c YES if
 you also set \ref cfg_generate_treeview "GENERATE_TREEVIEW" to \c YES.

<![CDATA[
 The \c 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 \c YES, 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 (i.e. any modern browser).
 Windows users are probably better off using the HTML help feature.

 Via custom style sheets (see \ref cfg_html_extra_stylesheet "HTML_EXTRA_STYLESHEET")
 one can further fine tune the look of the index (see \ref doxygen_finetune).
 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".

 Since the tree basically has the same information as the tab index, you could
 consider setting \ref cfg_disable_index "DISABLE_INDEX" to \c YES when
 enabling this option.

 the javascript based search engine can be slow, then enabling

 better solution.

 It is possible to search using the keyboard;
 to jump to the search box use <code>\<access key\> + S</code> (what the <code>\<access key\></code> is
 depends on the OS and browser, but it is typically <code>\<CTRL\></code>, <code>\<ALT\></code>/<code>\<option\></code>, or both).
 Inside the search box use the <code>\<cursor down key\></code> to jump into the search
 results window, the results can be navigated using the <code>\<cursor keys\></code>.
 Press <code>\<Enter\></code> to select an item or <code>\<escape\></code> to cancel the search. The
 filter options can be selected when the cursor is inside the search box

To cope with differences in the layout of the header and footer that depend on
 configuration settings, the header and footer can also contain special blocks that
 will be copied to the output or skipped depending on the configuration.
 Such blocks have the following form:
\verbatim
 %%BEGIN BLOCKNAME
 Some context copied when condition BLOCKNAME holds
 %%END BLOCKNAME
 %%BEGIN !BLOCKNAME
 Some context copied when condition BLOCKNAME does not hold
 %%END !BLOCKNAME
\endverbatim
The following block names are set based on the used settings in the
 configuration file:
 <dl>
 <dt><code>COMPACT_LATEX</code><dd>Content within this block is copied to the output
     when the \ref cfg_compact_latex "COMPACT_LATEX" option is enabled.
 <dt><code>PDF_HYPERLINKS</code><dd>Content within this block is copied to the output
     when the \ref cfg_pdf_hyperlinks "PDF_HYPERLINKS" option is enabled.
 <dt><code>USE_PDFLATEX</code><dd>Content within this block is copied to the output
     when the \ref cfg_use_pdflatex "USE_PDFLATEX" option is enabled.
 <dt><code>LATEX_BATCHMODE</code><dd>Content within this block is copied to the output
     when the \ref cfg_latex_batchmode "LATEX_BATCHMODE" option is enabled.
 <dt><code>LATEX_TIMESTAMP</code><dd>Content within this block is copied to the output
     when the \ref cfg_latex_timestamp "LATEX_TIMESTAMP" option is enabled.
 </dl>
The following block names are set based on the fact whether or not the tag has a
 value in the used configuration file:
 <dl>
 <dt><code>LATEX_FONTENC</code><dd>Content within this block is copied to the output
     when the doxygen latex translator function returns a value for the font encoding
     to be used. It is to be used in combination with the above mentioned `$latexfontenc`.
 <dt><code>FORMULA_MACROFILE</code><dd>Content within this block is copied to the output
     when the \ref cfg_formula_macrofile "FORMULA_MACROFILE" option is not empty. It is
     to be used in combination with the above mentioned `$formulamacrofile`.
 </dl>
The following block name is set based on whether or not a feature is used in the
 documentation:
 <dl>
 <dt><code>CITATIONS_PRESENT</code><dd>Content within this block is copied to the output
     when in the documentation citations are present and the relevant .. are present.
     It is to be used in combination with the above mentioned `$latexcitereference`,
     `$latexbibstyle` and `$latexbibfiles`.

 The \c TAGFILES tag can be used to specify one or more tag files.

For each

Adding location for the tag files is done as follows:

where `loc1` and `loc2` can be relative or absolute paths or URLs.
 See the section \ref external for more information about the use of tag files.

 \note
  Each tag file must have a unique name
