\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
PERL_PATH        = /usr/local/bin/perl
SEARCHENGINE     = NO
\endverbatim

To generate the documentation for the 
<a href="http://www.stack.nl/~dimitri/qdbttabular/index.html">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
PERL_PATH        = /usr/bin/perl
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

                       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

RECURSIVE             = YES
EXCLUDE_PATTERNS      = *codec.cpp moc_* */compat/* */3rdparty/*
ALPHABETICAL_INDEX    = YES
COLS_IN_ALPHA_INDEX   = 3
IGNORE_PREFIX         = Q
ENABLE_PREPROCESSING  = YES
MACRO_EXPANSION       = YES
INCLUDE_PATH          = $(QTDIR)/include

                        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[
 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

 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[
 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, C#, C, C++, D, PHP,
 Objective-C, Python, 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), VHDL. 

 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.

 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 CITE_BIB_FILES tag can be used to specify one or more \c bib files 
 containing the reference definitions. This must be a list of <code>.bib</code> files. The 
 <code>.bib</code> extension is automatically appended if omitted. This requires the

 more info. For \f$\mbox{\LaTeX}\f$ the style of the bibliography can be controlled 
 using \ref cfg_latex_bib_style "LATEX_BIB_STYLE".
 To use this feature you need \c bibtex and \c perl available in the search path.
 See also \ref cmdcite "\\cite" for info how to create references.

 -# Install the latest version of \c global

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

 Doxygen will invoke \c htags (and that will in turn invoke \c gtags), so these tools

 </dl>

 To cope with differences in the layout of the header and footer that depend on 
 configuration settings, the header 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 supported:
 <dl>
 <dt><code>DISABLE_INDEX</code><dd>Content within this block is copied to the output
     when the \ref cfg_disable_index "DISABLE_INDEX" option is enabled (so when the index is disabled).
 <dt><code>GENERATE_TREEVIEW</code><dd>Content within this block is copied to the output
     when the \ref cfg_generate_treeview "GENERATE_TREEVIEW" option is enabled.
 <dt><code>SEARCHENGINE</code><dd>Content within this block is copied to the output

 <dt><code>PROJECT_NAME</code><dd>Content within the block is copied to the output

 <dt><code>TITLEAREA</code><dd>Content within this block is copied to the output

 The \c HTML_EXTRA_STYLESHEET tag can be used to specify additional

 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 \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".

 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.

 When MathJax is enabled you need to specify the location relative to the 
 HTML output directory using the \c MATHJAX_RELPATH option. The destination 
 directory should contain the `MathJax.js` script. For instance, if the \c mathjax 
 directory is located at the same level as the HTML output directory, then 
 \c MATHJAX_RELPATH should be <code>../mathjax</code>. The default value points to 
 the MathJax Content Delivery Network so you can quickly see the result without 
 installing MathJax.  However, it is strongly recommended to install a local 
 copy of MathJax from https://www.mathjax.org before deployment.

<![CDATA[
 When the \c SEARCHENGINE tag is enabled doxygen will generate a search box
 for the HTML output. The underlying search engine uses javascript 
 and DHTML and should work on any modern browser. Note that when using
 HTML help (\ref cfg_generate_htmlhelp "GENERATE_HTMLHELP"), 
 Qt help (\ref cfg_generate_qhp "GENERATE_QHP"), or docsets
 (\ref cfg_generate_docset "GENERATE_DOCSET") there is already a search 
 function so this one should typically be disabled. For large projects 
 the javascript based search engine can be slow, then enabling 
 \ref cfg_server_based_search "SERVER_BASED_SEARCH" may provide a 
 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
 by pressing <code>\<Shift\>+\<cursor down\></code>. Also here use the <code>\<cursor keys\></code> to 
 select a filter and <code>\<Enter\></code> or <code>\<escape\></code> to activate or cancel the filter option.

 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
 \ref cfg_dot_graph_max_nodes "DOT_GRAPH_MAX_NODES". Using a depth of 0 means no depth restriction.

<![CDATA[
 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.
 <br>
 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).

<![CDATA[
 Set the \c DOT_MULTI_TARGETS tag to \c YES to allow dot to generate multiple output
 files in one run (i.e. multiple -o and -T options on the command line). This
 makes \c dot run faster, but since only newer versions of \c dot (>1.8.10)
 support this, this feature is disabled by default.

 If the \c GENERATE_LEGEND tag is set to \c YES doxygen will
 generate a legend page explaining the meaning of the various boxes and
 arrows in the dot generated graphs.
