+
+ ----- version 0.9 ------
+
+2006-07-29 Mark Lindner <markl@neuromancer>
+
+ * <multiple> - major grammar redesign: groups are now values instead of
+ distinct syntax constructs; this allows groups to be elements of
+ lists
+ * libconfig.texi - documentation updates; added new chapter containing
+ the BNF grammar
+ * test.cfg - modified to reflect new syntax and to demonstrate lists
+
+2006-06-23 Mark Lindner <markl@neuromancer>
+
+ * <multiple> - added support for lists (collections of
+ heterogeneous values of any type)
+ * libconfig.c - pretty-printing fixes in config_write()
+
+2006-06-08 Mark Lindner <markl@neuromancer>
+
+ * libconfig.h++ - added private copy constructor & assignment operator
+ (from Josef Meile)
+ * ligconfigcpp.c++, libconfig.h++ - added cast operators for unsigned
+ int and unsigned long (from Scott Frazer)
+ * <multiple> - add support for value formats; the only non-default
+ format currently supported is hexadecimal format for integer values
+ (based on patch from Scott Frazer)
+
+2006-04-15 Mark Lindner <markl@neuromancer>
+
+ * <multiple> - added pkg-config support
+
+2006-03-31 mlindner <markl@neuromancer>
+
+ * <multiple> - cleaned up config.tab.h mess (this file was obsolete,
+ and superseded by grammar.h ... problem identified by Scott Frazer)
+
+2006-03-30 mlindner <mlindner@chimera>
+
+ * grammar.y - fixed includes for windows (missing decl of malloc/free)
+ * libconfig.c - fixed several signed/unsigned warnings
+ * doc/libconfig.texi - documentation updates, formatting fix
+ * scanner.l - allow lowercase 'true' and 'false' in addition to
+ 'TRUE' and 'FALSE'
+
+2006-03-27 Mark Lindner <markl@neuromancer>
+
+ * libconfigcpp.c++ - added missing break statements in switch (from
+ Lukas Zweifel)
+ * libconfig.c - don't strdup() a NULL string (from Lukas Zweifel)
+ * grammar.c, grammar.h - regenerated with bison 2.1
+
+2006-03-20 Mark Lindner <markl@neuromancer>
+
+ * scanner.l - added '%option nounistd' and regenerated with newest
+ version of flex; Windows doesn't have unistd.h.
+
+2006-03-17 Mark Lindner <markl@neuromancer>
+
+ * grammar.y - bugfix; error & abort parsing if duplicate setting name
+ encountered (previously caused a crash ... reported by Tobias Witek)
+ * scanner.l - bugfix; multi-line C-style comments were causing line
+ number counting to be thrown off, because the newlines were being
+ "eaten"
+ * <multiple> - various fixes to support building of DLLs on Windows.
+
+2005-11-26 Mark Lindner <markl@neuromancer>
+
+ * grammar.y, scanner.l - always strdup() yytext, and free the memory
+ in the grammar rules.
+
+2005-11-22 Mark Lindner <markl@neuromancer>
+
+ * libconfigcpp.c++, libconfig.h++, libconfig.c, libconfig.h -
+ Added Daniel's enhancements: methods & functions for reading/writing
+ files, fixes for various memory leaks, etc.
+ * samples/* - Added Daniel's example code.
+ * docs/libconfig.texi - Updated documentation
+
+2005-09-28 Mark Lindner <markl@neuromancer>
+
+ * libconfigcpp.c++, libconfig.h++, libconfig.c, libconfig.h
+ Enhanced API to support modification of a configuration.
+ * libconfig.texi - updated manual
+
+2005-06-02 Mark Lindner <markl@neuromancer>
+
+ * libconfigcpp.c++, libconfig.h++ - Added getName() method;
+ fixed operator[](int) to work with groups; this allows iteration over
+ a group's child settings. Added a missing break statement (bugfix
+ submitted by Pablo Barrera Gonzalez). Added operator int() and
+ operator float() to Setting; note that these may cause loss of
+ precision since the actual values are stored internally as long
+ and double, respectively.
+
+ * libconfig.h - added config_setting_name() macro
+
+ * libconfig.c - maintain two lists of children at each node; a sorted
+ list and an unsorted list (to preserve the order of the settings as
+ they appear in the file).
+
+ * scanner.l - fixed scanner rule for comments. '#' no longer has to
+ be in column 0 to be recognized as a comment. Added support for C
+ and C++ style comments.

+\`configure' configures libconfig 1.4.9 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]

+ CPP C preprocessor
+ YACC The `Yet Another Compiler Compiler' implementation to use.
+ Defaults to the first program found out of: `bison -y', `byacc',
+ `yacc'.
+ YFLAGS The list of arguments that will be passed by default to $YACC.
+ This script will default YFLAGS to the empty string to avoid a

+@center Version 2.1, February 1999
+
+@sp 1
+
+Copyright @copyright{} 1991, 1999 Free Software Foundation, Inc.,
+59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+as the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+@sp 1
+@center Preamble
+@sp 1
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the Free
+Software Foundation and other authors who decide to use it. You can use
+it too, but we suggest you first think carefully about whether this
+license or the ordinary General Public License is the better strategy to
+use in any particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish); that you receive source code or can get it if
+you want it; that you can change the software and use pieces of it in
+new free programs; and that you are informed that you can do these
+things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or
+for a fee, you must give the recipients all the rights that we gave you.
+You must make sure that they, too, receive or can get the source code.
+If you link other code with the library, you must provide complete
+object files to the recipients, so that they can relink them with the
+library after making changes to the library and recompiling it. And you
+must show them these terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is
+no warranty for the free library. Also, if the library is modified by
+someone else and passed on, the recipients should know that what they
+have is not the original version, so that the original author's
+reputation will not be affected by problems that might be introduced by
+others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license
+obtained for a version of the library must be consistent with the full
+freedom of use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for
+certain libraries in order to permit linking those libraries into
+non-free programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the entire
+combination fits its criteria of freedom. The Lesser General Public
+License permits more lax criteria for linking other code with the
+library.
+
+We call this license the ``Lesser'' General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many libraries.
+However, the Lesser license provides advantages in certain special
+circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a
+de-facto standard. To achieve this, non-free programs must be allowed
+to use the library. A more frequent case is that a free library does
+the same job as widely used non-free libraries. In this case, there is
+little to gain by limiting the free library to free software only, so we
+use the Lesser General Public License.
+
+In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system,
+as well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is linked
+with the Library has the freedom and the wherewithal to run that program
+using a modified version of the Library.
+
+The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+``work based on the library'' and a ``work that uses the library''. The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+

+@center GNU LESSER GENERAL PUBLIC LICENSE
+@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+@enumerate 0
+
+@sp 1
+@item
+This License Agreement applies to any software library or other program
+which contains a notice placed by the copyright holder or other
+authorized party saying it may be distributed under the terms of this
+Lesser General Public License (also called ``this License''). Each
+licensee is addressed as ``you''.
+
+A ``library'' means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+The ``Library'', below, refers to any such software library or work which
+has been distributed under these terms. A ``work based on the Library''
+means either the Library or any derivative work under copyright law:
+that is to say, a work containing the Library or a portion of it, either
+verbatim or with modifications and/or translated straightforwardly into
+another language. (Hereinafter, translation is included without
+limitation in the term ``modification''.)
+
+``Source code'' for a work means the preferred form of the work for making
+modifications to it. For a library, complete source code means all the
+source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and
+installation of the library.
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of running
+a program using the Library is not restricted, and output from such a
+program is covered only if its contents constitute a work based on the
+Library (independent of the use of the Library in a tool for writing
+it). Whether that is true depends on what the Library does and what the
+program that uses the Library does.
+
+@sp 1
+@item
+You may copy and distribute verbatim copies of the Library's complete
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the notices
+that refer to this License and to the absence of any warranty; and
+distribute a copy of this License along with the Library.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+@sp 1
+@item
+You may modify your copy or copies of the Library or any portion of it,
+thus forming a work based on the Library, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that
+you also meet all of these conditions:
+
+@enumerate a
+
+@item
+The modified work must itself be a software library.
+
+@sp 1
+@item
+You must cause the files modified to carry prominent notices stating
+that you changed the files and the date of any change.
+
+@sp 1
+@item
+You must cause the whole of the work to be licensed at no charge to all
+third parties under the terms of this License.
+
+@sp 1
+@item
+If a facility in the modified Library refers to a function or a table of
+data to be supplied by an application program that uses the facility,
+other than as an argument passed when the facility is invoked, then you
+must make a good faith effort to ensure that, in the event an
+application does not supply such function or table, the facility still
+operates, and performs whatever part of its purpose remains meaningful.
+
+(For example, a function in a library to compute square roots has a
+purpose that is entirely well-defined independent of the application.
+Therefore, Subsection 2d requires that any application-supplied function
+or table used by this function must be optional: if the application does
+not supply it, the square root function must still compute square
+roots.)
+
+@end enumerate
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library, and
+can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based on
+the Library, the distribution of the whole must be on the terms of this
+License, whose permissions for other licensees extend to the entire
+whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of a
+storage or distribution medium does not bring the other work under the
+scope of this License.
+
+@sp 1
+@item
+You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so that
+they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+Once this change is made in a given copy, it is irreversible for that
+copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+This option is useful when you wish to copy part of the code of the
+Library into a program that is not a library.
+
+@sp 1
+@item
+You may copy and distribute the Library (or a portion or derivative of
+it, under Section 2) in object code or executable form under the terms
+of Sections 1 and 2 above provided that you accompany it with the
+complete corresponding machine-readable source code, which must be
+distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange.
+
+If distribution of object code is made by offering access to copy from a
+designated place, then offering equivalent access to copy the source
+code from the same place satisfies the requirement to distribute the
+source code, even though third parties are not compelled to copy the
+source along with the object code.
+
+@sp 1
+@item
+A program that contains no derivative of any portion of the Library, but
+is designed to work with the Library by being compiled or linked with
+it, is called a ``work that uses the Library''. Such a work, in
+isolation, is not a derivative work of the Library, and therefore falls
+outside the scope of this License.
+
+However, linking a ``work that uses the Library'' with the Library creates
+an executable that is a derivative of the Library (because it contains
+portions of the Library), rather than a ``work that uses the library''.
+The executable is therefore covered by this License. Section 6 states
+terms for distribution of such executables.
+
+When a ``work that uses the Library'' uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be linked
+without the Library, or if the work is itself a library. The threshold
+for this to be true is not precisely defined by law.
+
+If such an object file uses only numerical parameters, data structure
+layouts and accessors, and small macros and small inline functions (ten
+lines or less in length), then the use of the object file is
+unrestricted, regardless of whether it is legally a derivative work.
+(Executables containing this object code plus portions of the Library
+will still fall under Section 6.)
+
+Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6, whether
+or not they are linked directly with the Library itself.
+
+@sp 1
+@item
+As an exception to the Sections above, you may also combine or link a
+``work that uses the Library'' with the Library to produce a work
+containing portions of the Library, and distribute that work under terms
+of your choice, provided that the terms permit modification of the work
+for the customer's own use and reverse engineering for debugging such
+modifications.
+
+You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+@enumerate a
+
+@sp 1
+@item
+Accompany the work with the complete corresponding machine-readable
+source code for the Library including whatever changes were used in the
+work (which must be distributed under Sections 1 and 2 above); and, if
+the work is an executable linked with the Library, with the complete
+machine-readable ``work that uses the Library'', as object code and/or
+source code, so that the user can modify the Library and then relink to
+produce a modified executable containing the modified Library. (It is
+understood that the user who changes the contents of definitions files
+in the Library will not necessarily be able to recompile the application
+to use the modified definitions.)
+
+@sp 1
+@item
+Use a suitable shared library mechanism for linking with the Library. A
+suitable mechanism is one that (1) uses at run time a copy of the
+library already present on the user's computer system, rather than
+copying library functions into the executable, and (2) will operate
+properly with a modified version of the library, if the user installs
+one, as long as the modified version is interface-compatible with the
+version that the work was made with.
+
+@sp 1
+@item
+Accompany the work with a written offer, valid for at least three years,
+to give the same user the materials specified in Subsection 6a, above,
+for a charge no more than the cost of performing this distribution.
+
+@sp 1
+@item
+If distribution of the work is made by offering access to copy from a
+designated place, offer equivalent access to copy the above specified
+materials from the same place.
+
+@sp 1
+@item
+Verify that the user has already received a copy of these materials or
+that you have already sent this user a copy.
+
+@end enumerate
+
+For an executable, the required form of the ``work that uses the Library''
+must include any data and utility programs needed for reproducing the
+executable from it. However, as a special exception, the materials to
+be distributed need not include anything that is normally distributed
+(in either source or binary form) with the major components (compiler,
+kernel, and so on) of the operating system on which the executable runs,
+unless that component itself accompanies the executable.
+
+It may happen that this requirement contradicts the license restrictions
+of other proprietary libraries that do not normally accompany the
+operating system. Such a contradiction means you cannot use both them
+and the Library together in an executable that you distribute.
+
+@sp 1
+@item
+You may place library facilities that are a work based on the Library
+side-by-side in a single library together with other library facilities
+not covered by this License, and distribute such a combined library,
+provided that the separate distribution of the work based on the Library
+and of the other library facilities is otherwise permitted, and provided
+that you do these two things:
+
+@enumerate a
+
+@sp 1
+@item
+Accompany the combined library with a copy of the same work based on the
+Library, uncombined with any other library facilities. This must be
+distributed under the terms of the Sections above.
+
+@sp 1
+@item
+Give prominent notice with the combined library of the fact that part of
+it is a work based on the Library, and explaining where to find the
+accompanying uncombined form of the same work.
+
+@end enumerate
+
+@sp 1
+@item
+You may not copy, modify, sublicense, link with, or distribute the
+Library except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, link with, or distribute the
+Library is void, and will automatically terminate your rights under this
+License. However, parties who have received copies, or rights, from you
+under this License will not have their licenses terminated so long as
+such parties remain in full compliance.
+
+@sp 1
+@item
+You are not required to accept this License, since you have not signed
+it. However, nothing else grants you permission to modify or distribute
+the Library or its derivative works. These actions are prohibited by
+law if you do not accept this License. Therefore, by modifying or
+distributing the Library (or any work based on the Library), you
+indicate your acceptance of this License to do so, and all its terms and
+conditions for copying, distributing or modifying the Library or works
+based on it.
+
+@sp 1
+@item
+Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the

+You are not responsible for enforcing compliance by third parties with

+
+@i{Libconfig} is a library for reading, manipulating, and writing
+structured configuration files. The library features a fully
+reentrant parser and includes bindings for both the C and C++
+programming languages.
+
+The library runs on modern POSIX-compilant systems, such as Linux,
+Solaris, and Mac OS X (Darwin), as well as on Microsoft Windows
+2000/XP and later (with either Microsoft Visual Studio 2005 or later,
+or the GNU toolchain via the MinGW environment).

+@section Why Another Configuration File Library?
+
+There are several open-source configuration file libraries available
+as of this writing. This library was written because each of those
+libraries falls short in one or more ways. The main features of
+@i{libconfig} that set it apart from the other libraries are:
+
+@itemize @bullet
+
+@item A fully reentrant parser. Independent configurations can be parsed in concurrent threads at the same time.
+
+@item Both C @i{and} C++ bindings, as well as hooks to allow for the creation of wrappers in other languages.
+
+@item A simple, structured configuration file format that is more
+readable and compact than XML and more flexible than the obsolete but
+prevalent Windows ``INI'' file format.
+
+@item A low-footprint implementation (just 37K for the C library and 76K for
+the C++ library) that is suitable for memory-constrained systems.
+
+@item Proper documentation.

+@node Multithreading Issues, Internationalization Issues, Using the Library from a C++ Program, Introduction
+@comment node-name, next, previous, up
+@section Multithreading Issues
+
+@i{Libconfig} is fully @dfn{reentrant}; the functions in the library
+do not make use of global variables and do not maintain state between
+successive calls. Therefore two independent configurations may be safely
+manipulated concurrently by two distinct threads.
+
+@i{Libconfig} is not @dfn{thread-safe}. The library is not aware of
+the presence of threads and knows nothing about the host system's
+threading model. Therefore, if an instance of a configuration is to be
+accessed from multiple threads, it must be suitably protected by
+synchronization mechanisms like read-write locks or mutexes; the
+standard rules for safe multithreaded access to shared data must be
+observed.
+
+@i{Libconfig} is not @dfn{async-safe}. Calls should not be made into
+the library from signal handlers, because some of the C library
+routines that it uses may not be async-safe.
+
+@i{Libconfig} is not guaranteed to be @dfn{cancel-safe}. Since it is
+not aware of the host system's threading model, the library does not
+contain any thread cancellation points. In most cases this will not be
+an issue for multithreaded programs. However, be aware that some of
+the routines in the library (namely those that read/write
+configurations from/to files or streams) perform I/O using C library
+routines which may potentially block; whether or not these C library
+routines are cancel-safe depends on the host system.
+
+@node Internationalization Issues, Compiling Using pkg-config, Multithreading Issues, Introduction
+@comment node-name, next, previous, up
+@section Internationalization Issues
+
+@cindex Unicode
+@cindex UTF-8
+@i{Libconfig} does not natively support Unicode configuration files,
+but string values may contain Unicode text encoded in UTF-8; such
+strings will be treated as ordinary 8-bit ASCII text by the
+library. It is the responsibility of the calling program to perform
+the necessary conversions to/from wide (@t{wchar_t}) strings using the
+wide string conversion functions such as @t{mbsrtowcs()} and
+@t{wcsrtombs()} or the @t{iconv()} function of the @i{libiconv}
+library.
+
+@cindex locale
+The textual representation of a floating point value varies by
+locale. However, the @i{libconfig} grammar specifies that
+floating point values are represented using a period (`.') as the
+radix symbol; this is consistent with the grammar of most programming
+languages. When a configuration is read in or written out,
+@i{libconfig} temporarily changes the @t{LC_NUMERIC} category of the
+locale of the calling thread to the ``C'' locale to ensure consistent
+handling of floating point values regardless of the locale(s) in use
+by the calling program.
+
+Note that the MinGW environment does not (as of this writing) provide
+functions for changing the locale of the calling thread. Therefore,
+when using @i{libconfig} in that environment, the calling program is
+responsible for changing the @t{LC_NUMERIC} category of the locale to
+the "C" locale before reading or writing a configuration.
+
+@node Compiling Using pkg-config, Version Test Macros, Internationalization Issues, Introduction
+@comment node-name, next, previous, up
+@section Compiling Using pkg-config
+
+On UNIX systems you can use the @i{pkg-config} utility (version 0.20
+or later) to automatically select the appropriate compiler and linker
+switches for @i{libconfig}. Ensure that the environment variable
+@code{PKG_CONFIG_PATH} contains the absolute path to the
+@file{lib/pkgconfig} subdirectory of the @i{libconfig} installation. Then,
+you can compile and link C programs with @i{libconfig} as follows:
+
+@smallexample
+gcc `pkg-config --cflags libconfig` myprogram.c -o myprogram \
+ `pkg-config --libs libconfig`
+@end smallexample
+@sp 1
+
+And similarly, for C++ programs:
+
+@smallexample
+g++ `pkg-config --cflags libconfig++` myprogram.cpp -o myprogram \
+ `pkg-config --libs libconfig++`
+@end smallexample
+
+@sp 1
+Note the backticks in the above examples.
+
+When using @b{autoconf}, the @code{PKG_CHECK_MODULES} m4 macro may be used to check for the presence of a given version of @i{libconfig}, and set the appropriate Makefile variables automatically. For example:
+
+@smallexample
+PKG_CHECK_MODULES([LIBCONFIGXX], [libconfig++ >= 1.4],,
+ AC_MSG_ERROR([libconfig++ 1.4 or newer not found.])
+)
+@end smallexample
+
+In the above example, if @i{libconfig++} version 1.4 or newer is found,
+the Makefile variables @code{LIBCONFIGXX_LIBS} and @code{LIBCONFIGXX_CFLAGS} will be
+set to the appropriate compiler and linker flags for compiling with
+@i{libconfig}, and if it is not found, the configure script will abort
+with an error to that effect.
+
+@node Version Test Macros, , Compiling Using pkg-config, Introduction
+@comment node-name, next, previous, up
+@section Version Test Macros
+
+The @file{libconfig.h} header declares the following macros:
+
+@defmac LIBCONFIG_VER_MAJOR
+@defmacx LIBCONFIG_VER_MINOR
+@defmacx LIBCONFIG_VER_REVISION
+
+These macros represent the major version, minor version, and revision
+of the @i{libconfig} library. For example, in @i{libconfig} 1.4 these
+are defined as @samp{1}, @samp{4}, and @samp{0}, respectively. These
+macros can be used in preprocessor directives to determine which
+@i{libconfig} features and/or APIs are present. For example:
+
+@smallexample
+#if (((LIBCONFIG_VER_MAJOR == 1) && (LIBCONFIG_VER_MINOR >= 4)) \
+ || (LIBCONFIG_VER_MAJOR > 1))
+ /* use features present in libconfig 1.4 and later */
+#endif
+@end smallexample
+
+These macros were introduced in @i{libconfig} 1.4.
+

+Similarly, the @file{libconfig.h++} header declares the following macros:
+
+@defmac LIBCONFIGXX_VER_MAJOR
+@defmacx LIBCONFIGXX_VER_MINOR

+@end smallexample
+@end cartouche
+@sp 1
+
+@cindex path
+Settings can be uniquely identified within the configuration by a
+@dfn{path}. The path is a dot-separated sequence of names, beginning
+at a top-level group and ending at the setting itself. Each name in
+the path is the name of a setting; if the setting has no name because
+it is an element in a list or array, an integer index in square
+brackets can be used as the name.
+
+For example, in our hypothetical configuration file, the path to the
+@code{x} setting is @code{application.window.pos.x}; the path to the
+@code{version} setting is simply @code{version}; and the path to the
+@code{title} setting of the second book in the @code{books} list is
+@code{application.books.[1].title}.
+
+The datatype of a value is determined from the format of the value
+itself. If the value is enclosed in double quotes, it is treated as a
+string. If it looks like an integer or floating point number, it is
+treated as such. If it is one of the values @code{TRUE}, @code{true},
+@code{FALSE}, or @code{false} (or any other mixed-case version of
+those tokens, e.g., @code{True} or @code{FaLsE}), it is treated as a
+boolean. If it consists of a comma-separated list of values enclosed
+in square brackets, it is treated as an array. And if it consists of a
+comma-separated list of values enclosed in parentheses, it is treated
+as a list. Any value which does not meet any of these criteria is
+considered invalid and results in a parse error.
+
+All names are case-sensitive. They may consist only of alphanumeric
+characters, dashes (@samp{-}), underscores (@samp{_}), and asterisks
+(@samp{*}), and must begin with a letter or asterisk. No other
+characters are allowed.
+
+In C and C++, integer, 64-bit integer, floating point, and string
+values are mapped to the types @code{int}, @code{long long},
+@code{double}, and @code{const char *}, respectively. The boolean type
+is mapped to @code{int} in C and @code{bool} in C++.

+grammar in additional detail.

+except that an 'L' character is appended to indicate a 64-bit
+value. For example, @samp{0L} indicates a 64-bit integer value 0.

+@section Floating Point Values
+
+Floating point values consist of a series of one or more digits, one
+decimal point, an optional leading sign character (@samp{+} or
+@samp{-}), and an optional exponent. An exponent consists of the
+letter @samp{E} or @samp{e}, an optional sign character, and a series
+of one or more digits.

+@samp{false}, or any mixed-case variation thereof.

+@section String Values
+
+@cindex escape sequence
+String values consist of arbitrary text delimited by double
+quotes. Literal double quotes can be escaped by preceding them with a
+backslash: @samp{\"}. The escape sequences @samp{\\}, @samp{\f},
+@samp{\n}, @samp{\r}, and @samp{\t} are also recognized, and have the
+usual meaning.
+
+In addition, the @samp{\x} escape sequence is supported; this sequence
+must be followed by @i{exactly two} hexadecimal digits, which represent an
+8-bit ASCII value. For example, @samp{\xFF} represents the character
+with ASCII code 0xFF.
+
+No other escape sequences are currently supported.
+
+Adjacent strings are automatically concatenated, as in C/C++ source
+code. This is useful for formatting very long strings as sequences of
+shorter strings. For example, the following constructs are equivalent:
+
+@itemize @bullet
+@item
+@code{"The quick brown fox jumped over the lazy dog."}
+
+@item
+@code{"The quick brown fox"} @*
+@code{" jumped over the lazy dog."}

+@node Comments, Include Directives, String Values, Configuration Files

+@section Comments
+
+@cindex comment
+Three types of comments are allowed within a configuration:
+
+@itemize @bullet
+
+@item Script-style comments. All text beginning with a @samp{#} character
+to the end of the line is ignored.
+
+@item C-style comments. All text, including line breaks, between a starting
+@samp{/*} sequence and an ending @samp{*/} sequence is ignored.
+
+@item C++-style comments. All text beginning with a @samp{//} sequence to the
+end of the line is ignored.
+
+@end itemize
+
+As expected, comment delimiters appearing within quoted strings are
+treated as literal text.
+
+Comments are ignored when the configuration is read in, so they are
+not treated as part of the configuration. Therefore if the
+configuration is written back out to a stream, any comments that were
+present in the original configuration will be lost.

+@node Include Directives, , Comments, Configuration Files
+@comment node-name, next, previous, up
+@section Include Directives
+
+@cindex include directive
+A configuration file may ``include'' the contents of another file
+using an @i{include directive}. This directive has the effect of
+inlining the contents of the named file at the point of inclusion.
+
+An include directive must appear on its own line in the input. It has
+the form:
+
+@b{@@include "}@i{filename}@b{"}
+
+Any backslashes or double quotes in the filename must be escaped as
+@samp{\\} and @samp{\"}, respectively.
+
+For example, consider the following two configuration files:
+
+@cartouche
+@smallexample
+# file: quote.cfg
+quote = "Criticism may not be agreeable, but it is necessary."
+ " It fulfils the same function as pain in the human"
+ " body. It calls attention to an unhealthy state of"
+ " things.\n"
+ "\t--Winston Churchill";
+@end smallexample
+@end cartouche
+
+@cartouche
+@smallexample
+# file: test.cfg
+info: @{
+ name = "Winston Churchill";
+ @@include "quote.cfg"
+ country = "UK";
+@};
+@end smallexample
+@end cartouche
+
+Include files may be nested to a maximum of 10 levels; exceeding this
+limit results in a parse error.
+
+Like comments, include directives are not part of the configuration
+file syntax. They are processed before the configuration itself is
+parsed. Therefore, they are not preserved when the configuration is
+written back out to a stream. There is presently no support for
+programmatically inserting include directives into a configuration.

+
+@tindex Config
+@tindex Setting
+This chapter describes the C++ library API. The class @code{Config}
+represents a configuration, and the class @code{Setting} represents a
+configuration setting. Note that by design, neither of these classes
+provides a public copy constructor or assignment operator. Therefore,
+instances of these classes may only be passed between functions via
+references or pointers.
+
+@tindex ConfigException
+The library defines a group of exceptions, all of which extend the
+common base exception @code{ConfigException}.
+
+@tindex SettingTypeException
+A @code{SettingTypeException} is thrown when the type of a setting's
+value does not match the type requested.
+
+@tindex SettingNotFoundException
+A @code{SettingNotFoundException} is thrown when a setting is not found.
+
+@tindex SettingNameException
+A @code{SettingNameException} is thrown when an attempt is made to add
+a new setting with a non-unique or invalid name.
+
+@tindex ParseException
+A @code{ParseException} is thrown when a parse error occurs while
+reading a configuration from a stream.
+
+@tindex FileIOException
+A @code{FileIOException} is thrown when an I/O error occurs while
+reading/writing a configuration from/to a file.
+
+@tindex SettingException
+@code{SettingTypeException}, @code{SettingNotFoundException}, and
+@code{SettingNameException} all extend the common base
+exception @code{SettingException}, which provides the following method:
+
+@deftypemethod SettingException {const char *} getPath ()
+
+Returns the path to the setting associated with the exception, or
+@code{NULL} if there is no applicable path.
+
+@end deftypemethod
+
+The remainder of this chapter describes the methods for manipulating
+configurations and configuration settings.
+
+@deftypemethod Config {} Config ()
+@deftypemethodx Config {} ~Config ()
+
+These methods create and destroy @code{Config} objects.
+
+@end deftypemethod
+
+@deftypemethod Config void read (@w{FILE * @var{stream}})
+@deftypemethodx Config void write (@w{FILE * @var{stream}})
+
+The @code{read()} method reads and parses a configuration from the given
+@var{stream}. A @code{ParseException} is thrown if a parse error occurs.
+
+The @code{write()} method writes the configuration to the given @var{stream}.
+
+@end deftypemethod
+
+@deftypemethod Config void readFile (@w{const char * @var{filename}})
+@deftypemethodx Config void writeFile (@w{const char * @var{filename}})
+
+The @code{readFile()} method reads and parses a configuration from the
+file named @var{filename}. A @code{ParseException} is thrown if a
+parse error occurs. A @code{FileIOException} is thrown if the file
+cannot be read.
+
+The @code{writeFile()} method writes the configuration to the file
+named @var{filename}. A @code{FileIOException} is thrown if the file cannot
+be written.
+
+@end deftypemethod
+
+@deftypemethod Config void readString (@w{const char * @var{str}})
+@deftypemethodx Config void readString (@w{const std::string &@var{str}})
+
+These methods read and parse a configuration from the string
+@var{str}. A @code{ParseException} is thrown if a parse error occurs.
+
+@end deftypemethod
+
+@deftypemethod ParseException {const char *} getError ()
+@deftypemethodx ParseException {const char *} getFile ()
+@deftypemethodx ParseException int getLine ()
+
+If a call to @code{readFile()}, @code{readString()}, or @code{read()}
+resulted in a @code{ParseException}, these methods can be called on
+the exception object to obtain the text, filename, and line number of
+the parse error. Storage for the strings returned by @code{getError()}
+and @code{getFile()} are managed by the library; the strings must not
+be freed by the caller.
+
+@end deftypemethod
+
+@deftypemethod Config void setIncludeDir (@w{const char *@var{includeDir}})
+@deftypemethodx Config {const char *} getIncludeDir ()
+
+@code{setIncludeDir()} specifies the include directory,
+@var{includeDir}, relative to which the files specified in
+@samp{@@include} directives will be located for the configuration. By
+default, there is no include directory, and all include files are
+expected to be relative to the current working directory. If
+@var{includeDir} is @code{NULL}, the default behavior is reinstated.
+
+For example, if the include directory is set to @file{/usr/local/etc},
+the include directive @samp{@@include "configs/extra.cfg"} would include the
+file @file{/usr/local/etc/configs/extra.cfg}.
+
+@code{getIncludeDir()} returns the current include directory for the
+configuration, or @code{NULL} if none is set.
+
+@end deftypemethod
+
+@deftypemethod Config void setAutoConvert (bool @var{flag})
+@deftypemethodx Config bool getAutoConvert ()
+
+@code{setAutoConvert()} enables number auto-conversion for the
+configuration if @var{flag} is @code{true}, and disables it
+otherwise. When this feature is enabled, an attempt to assign a
+floating point setting to an integer (or vice versa), or
+assign an integer to a floating point setting (or vice versa) will
+cause the library to silently perform the necessary conversion
+(possibly leading to loss of data), rather than throwing a
+@code{SettingTypeException}. By default this feature is disabled.
+
+@code{getAutoConvert()} returns @code{true} if number auto-conversion
+is currently enabled for the configuration; otherwise it returns
+@code{false}.
+
+@end deftypemethod
+
+@deftypemethod Config void setDefaultFormat (@w{Setting::Format @var{format}})
+@deftypemethodx Config Setting::Format getDefaultFormat ()
+
+These methods set and get the default external format for settings in
+the configuration. If a non-default format has not been set for a
+setting with @code{Setting::setFormat()}, this configuration-wide
+default format will be used instead when that setting is written to a
+file or stream.
+
+@end deftypemethod
+
+@deftypemethod Config void setTabWidth (@w{unsigned short @var{width}})
+@deftypemethodx Config {unsigned short} getTabWidth ()
+
+These methods set and get the tab width for the configuration. The tab
+width affects the formatting of the configuration when it is written
+to a file or stream: each level of nesting is indented by @var{width}
+spaces, or by a single tab character if @var{width} is 0. The tab
+width has no effect on parsing.
+
+Valid tab widths range from 0 to 15. The default tab width is 2.
+
+@end deftypemethod
+
+@deftypemethod Config {Setting &} getRoot ()
+
+This method returns the root setting for the configuration, which is a group.
+
+@end deftypemethod
+
+@deftypemethod Config {Setting &} lookup (@w{const std::string &@var{path}})
+@deftypemethodx Config {Setting &} lookup (@w{const char * @var{path}})
+
+These methods locate the setting specified by the path @var{path}. If
+the requested setting is not found, a @code{SettingNotFoundException} is
+thrown.
+
+@end deftypemethod
+@deftypemethod Config bool exists (@w{const std::string &@var{path}})
+@deftypemethodx Config bool exists (@w{const char *@var{path}})
+
+These methods test if a setting with the given @var{path} exists in
+the configuration. They return @code{true} if the setting exists, and
+@code{false} otherwise. These methods do not throw exceptions.
+
+@end deftypemethod
+
+@deftypemethod Config bool lookupValue (@w{const char *@var{path}}, @w{bool &@var{value}})
+@deftypemethodx Config bool lookupValue (@w{const std::string &@var{path}}, @w{bool &@var{value}})
+
+@deftypemethodx Config bool lookupValue (@w{const char *@var{path}}, @w{int &@var{value}})
+@deftypemethodx Config bool lookupValue (@w{const std::string &@var{path}}, @w{int &@var{value}})
+
+@deftypemethodx Config bool lookupValue (@w{const char *@var{path}}, @w{unsigned int &@var{value}})
+@deftypemethodx Config bool lookupValue (@w{const std::string &@var{path}}, @w{unsigned int &@var{value}})
+
+@deftypemethodx Config bool lookupValue (@w{const char *@var{path}}, @w{long long &@var{value}})
+@deftypemethodx Config bool lookupValue (@w{const std::string &@var{path}}, @w{long long &@var{value}})
+
+@deftypemethodx Config bool lookupValue (@w{const char *@var{path}}, @w{float &@var{value}})
+@deftypemethodx Config bool lookupValue (@w{const std::string &@var{path}}, @w{float &@var{value}})
+
+@deftypemethodx Config bool lookupValue (@w{const char *@var{path}}, @w{double &@var{value}})
+@deftypemethodx Config bool lookupValue (@w{const std::string &@var{path}}, @w{double &@var{value}})
+
+@deftypemethodx Config bool lookupValue (@w{const char *@var{path}}, @w{const char *&@var{value}})
+@deftypemethodx Config bool lookupValue (@w{const std::string &@var{path}}, @w{const char *&@var{value}})
+
+@deftypemethodx Config bool lookupValue (@w{const char *@var{path}}, @w{std::string &@var{value}})
+@deftypemethodx Config bool lookupValue (@w{const std::string &@var{path}}, @w{std::string &@var{value}})
+
+These are convenience methods for looking up the value of a setting
+with the given @var{path}. If the setting is found and is of an
+appropriate type, the value is stored in @var{value} and the method
+returns @code{true}. Otherwise, @var{value} is left unmodified and the
+method returns @code{false}. These methods do not throw exceptions.
+
+Storage for @w{@i{const char *}} values is managed by the library and
+released automatically when the setting is destroyed or when its value
+is changed; the string must not be freed by the caller. For safety and
+convenience, always assigning string values to a @code{std::string} is
+suggested.
+
+Since these methods have boolean return values and do not throw
+exceptions, they can be used within boolean logic expressions. The following
+example presents a concise way to look up three values at once and
+perform error handling if any of them are not found or are of the
+wrong type:
+
+@sp 1
+@cartouche
+@smallexample
+int var1;
+double var2;
+const char *var3;
+
+if(config.lookupValue("values.var1", var1)
+ && config.lookupValue("values.var2", var2)
+ && config.lookupValue("values.var3", var3))
+@{
+ // use var1, var2, var3
+@}
+else
+@{
+ // error handling here
+@}
+@end smallexample
+@end cartouche
+
+This approach also takes advantage of the short-circuit evaluation rules
+of C++, e.g., if the first lookup fails (returning @code{false}), the
+remaining lookups are skipped entirely.
+
+@end deftypemethod
+
+@deftypemethod Setting {} {operator bool ()}
+@deftypemethodx Setting {} {operator int ()}
+@deftypemethodx Setting {} {operator unsigned int ()}
+@deftypemethodx Setting {} {operator long ()}
+@deftypemethodx Setting {} {operator unsigned long ()}
+@deftypemethodx Setting {} {operator long long ()}
+@deftypemethodx Setting {} {operator unsigned long long ()}
+@deftypemethodx Setting {} {operator float ()}
+@deftypemethodx Setting {} {operator double ()}
+@deftypemethodx Setting {} {operator const char * ()}
+@deftypemethodx Setting {} {operator std::string ()}
+@deftypemethodx Setting {const char *} c_str ()
+
+These cast operators allow a @code{Setting} object to be assigned to a
+variable of type @i{bool} if it is of type @code{TypeBoolean};
+@i{int}, @i{unsigned int}; @code{long long} or @code{unsigned long long} if
+it is of type @code{TypeInt64}, @i{float} or @i{double} if it is of type
+@code{TypeFloat}; or @w{@i{const char *}} or @i{std::string} if it is
+of type @code{TypeString}.
+
+Values of type @code{TypeInt} or @code{TypeInt64} may be assigned to
+variables of type @i{long}, or @i{unsigned long}, depending on the
+sizes of those types on the host system.
+
+Storage for @w{@i{const char *}} return values is managed by the
+library and released automatically when the setting is destroyed or
+when its value is changed; the string must not be freed by the
+caller. For safety and convenience, always assigning string return
+values to a @code{std::string} is suggested.
+
+The following examples demonstrate this usage:
+
+@cartouche
+@smallexample
+long width = config.lookup("application.window.size.w");
+
+bool splashScreen = config.lookup("application.splash_screen");
+
+std::string title = config.lookup("application.window.title");
+@end smallexample
+@end cartouche
+
+Note that certain conversions can lead to loss of precision or
+clipping of values, e.g., assigning a negative value to an @i{unsigned
+int} (in which case the value will be treated as 0), or a
+double-precision value to a @i{float}. The library does not treat
+these lossy conversions as errors.
+
+Perhaps surprisingly, the following code in particular will cause a
+compiler error:
+
+@cartouche
+@smallexample
+std::string title;
+.
+.
+.
+title = config.lookup("application.window.title");
+@end smallexample
+@end cartouche
+
+This is because the assignment operator of @code{std::string} is being
+invoked with a @code{Setting &} as an argument. The compiler is unable
+to make an implicit conversion because both the @code{const char *}
+and the @code{std::string} cast operators of @code{Setting} are
+equally appropriate. This is not a bug in @i{libconfig}; providing
+only the @code{const char *} cast operator would resolve this
+particular ambiguity, but would cause assignments to
+@code{std::string} like the one in the previous example to produce a
+compiler error. (To understand why, see section 11.4.1 of @i{The C++
+Programming Language}.)
+
+The solution to this problem is to use an explicit conversion that
+avoids the construction of an intermediate @code{std::string} object,
+as follows:
+
+@cartouche
+@smallexample
+std::string title;
+.
+.
+.
+title = (const char *)config.lookup("application.window.title");
+@end smallexample
+@end cartouche
+
+Or, alternatively, use the @code{c_str()} method, which has the same effect:
+
+@cartouche
+@smallexample
+std::string title;
+.
+.
+.
+title = config.lookup("application.window.title").c_str();
+@end smallexample
+@end cartouche
+
+If the assignment is invalid due to a type mismatch, a
+@code{SettingTypeException} is thrown.
+
+@end deftypemethod
+
+@deftypemethod Setting {Setting &} operator= (@w{bool @var{value}})
+@deftypemethodx Setting {Setting &} operator= (@w{int @var{value}})
+@deftypemethodx Setting {Setting &} operator= (@w{long @var{value}})
+@deftypemethodx Setting {Setting &} operator= (@w{const long long &@var{value}})
+@deftypemethodx Setting {Setting &} operator= (@w{float @var{value}})
+@deftypemethodx Setting {Setting &} operator= (@w{const double &@var{value}})
+@deftypemethodx Setting {Setting &} operator= (@w{const char *@var{value}})
+@deftypemethodx Setting {Setting &} operator= (@w{const std::string &@var{value}})
+
+These assignment operators allow values of type @i{bool}, @i{int},
+@i{long}, @i{long long}, @i{float}, @i{double}, @i{const char *}, and
+@i{std::string} to be assigned to a setting. In the case of strings,
+the library makes a copy of the passed string @var{value}, so it may
+be subsequently freed or modified by the caller without affecting the
+value of the setting.
+
+The following example code looks up a (presumably) integer setting
+and changes its value:
+
+@cartouche
+@smallexample
+Setting &setting = config.lookup("application.window.size.w");
+setting = 1024;
+@end smallexample
+@end cartouche
+
+If the assignment is invalid due to a type mismatch, a
+@code{SettingTypeException} is thrown.
+
+@end deftypemethod
+
+@deftypemethod Setting {Setting &} {operator[]} (@w{int @var{index}})
+@deftypemethodx Setting {Setting &} {operator[]} (@w{const std::string &@var{name}})
+@deftypemethodx Setting {Setting &} {operator[]} (@w{const char *@var{name}})
+
+A @code{Setting} object may be subscripted with an integer index
+@var{index} if it is an array or list, or with either a string
+@var{name} or an integer index @var{index} if it is a group. For example,
+the following code would produce the string @samp{Last Name} when
+applied to the example configuration in @ref{Configuration Files}.
+
+@cartouche
+@smallexample
+Setting& setting = config.lookup("application.misc");
+const char *s = setting["columns"][0];
+@end smallexample
+@end cartouche
+
+If the setting is not an array, list, or group, a
+@code{SettingTypeException} is thrown. If the subscript (@var{index}
+or @var{name}) does not refer to a valid element, a
+@code{SettingNotFoundException} is thrown.
+
+Iterating over a group's child settings with an integer index will
+return the settings in the same order that they appear in the
+configuration.

+These are convenience methods for looking up the value of a child setting

+@deftypemethodx Setting {Setting &} add (@w{const char *@var{name}}, @w{Setting::Type @var{type}})
+
+These methods add a new child setting with the given @var{name} and
+@var{type} to the setting, which must be a group. They return a
+reference to the new setting. If the setting already has a child
+setting with the given name, or if the name is invalid, a

+a @code{SettingTypeException} is thrown.
+
+Once a setting has been created, neither its name nor type can be

+
+@end deftypemethod
+
+@deftypemethod Setting {Setting &} add (@w{Setting::Type @var{type}})
+
+This method adds a new element to the setting, which must be of type

+currently has zero elements, the @var{type} parameter (which must be
+@code{TypeInt}, @code{TypeInt64}, @code{TypeFloat}, @code{TypeBool},
+or @code{TypeString}) determines the type for the array; otherwise it
+must match the type of the existing elements in the array.
+
+The method returns the new setting on success. If @var{type} is a
+scalar type, the new setting will have a default value of 0, 0.0,
+@code{false}, or @code{NULL}, as appropriate.
+
+The method throws a @code{SettingTypeException} if the setting is not

+setting are recursively destroyed as well.
+
+If the setting is not a group, a @code{SettingTypeException} is

+@end deftypemethod
+
+@deftypemethod Setting {const char *} getName ()
+
+This method returns the name of the setting, or @code{NULL} if the
+setting has no name. Storage for the returned string is managed by the
+library and released automatically when the setting is destroyed; the
+string must not be freed by the caller. For safety and convenience,
+consider assigning the return value to a @code{std::string}.
+
+@end deftypemethod
+
+@deftypemethod Setting {std::string} getPath ()
+
+This method returns the complete dot-separated path to the
+setting. Settings which do not have a name (list and array elements)
+are represented by their index in square brackets.
+
+@end deftypemethod
+
+@deftypemethod Setting {Setting &} getParent ()
+
+This method returns the parent setting of the setting. If the setting
+is the root setting, a @code{SettingNotFoundException} is thrown.
+
+@end deftypemethod
+
+@deftypemethod Setting bool isRoot ()
+
+This method returns @code{true} if the setting is the root setting, and
+@code{false} otherwise.
+
+@end deftypemethod
+
+@deftypemethod Setting int getIndex ()
+
+This method returns the index of the setting within its parent
+setting. When applied to the root setting, this method returns -1.
+
+@end deftypemethod
+
+@deftypemethod Setting Setting::Type getType ()
+
+@tindex Setting::Type
+This method returns the type of the setting. The
+@code{Setting::Type} enumeration consists of the following constants:
+@code{TypeInt}, @code{TypeInt64}, @code{TypeFloat}, @code{TypeString},
+@code{TypeBoolean}, @code{TypeArray}, @code{TypeList}, and
+@code{TypeGroup}.
+
+@end deftypemethod
+
+@deftypemethod Setting Setting::Format getFormat ()
+@deftypemethodx Setting void setFormat (@w{Setting::Format @var{format}})
+
+These methods get and set the external format for the setting.
+
+@tindex Setting::Format
+The @var{Setting::Format} enumeration consists of the following
+constants: @code{FormatDefault} and @code{FormatHex}. All settings
+support the @code{FormatDefault} format. The @code{FormatHex} format
+specifies hexadecimal formatting for integer values, and hence only
+applies to settings of type @code{TypeInt} and @code{TypeInt64}. If
+@var{format} is invalid for the given setting, it is ignored.
+
+@end deftypemethod
+
+@deftypemethod Setting bool exists (@w{const std::string &@var{name}})
+@deftypemethodx Setting bool exists (@w{const char *@var{name}})
+
+These methods test if the setting has a child setting with the given
+@var{name}. They return @code{true} if the setting exists, and
+@code{false} otherwise. These methods do not throw exceptions.
+
+@end deftypemethod
+
+@deftypemethod Setting int getLength ()
+
+This method returns the number of settings in a group, or the number of
+elements in a list or array. For other types of settings, it returns
+0.
+
+@end deftypemethod
+
+@deftypemethod Setting bool isGroup ()
+@deftypemethodx Setting bool isArray ()
+@deftypemethodx Setting bool isList ()
+
+These convenience methods test if a setting is of a given type.
+
+@end deftypemethod
+
+@deftypemethod Setting bool isAggregate ()
+@deftypemethodx Setting bool isScalar ()
+@deftypemethodx Setting bool isNumber ()
+
+These convenience methods test if a setting is of an aggregate type (a
+group, array, or list), of a scalar type (integer, 64-bit integer,
+floating point, boolean, or string), and of a number (integer, 64-bit
+integer, or floating point), respectively.
+
+@end deftypemethod
+
+@deftypemethod Setting {const char *} getSourceFile ()
+
+This function returns the name of the file from which the setting was
+read, or NULL if the setting was not read from a file. This
+information is useful for reporting application-level errors. Storage
+for the returned string is managed by the library and released
+automatically when the configuration is destroyed; the string must
+not be freed by the caller.
+
+@end deftypemethod
+
+@deftypemethod Setting {unsigned int} getSourceLine ()
+
+This function returns the line number of the configuration file or
+stream at which the setting @var{setting} was read, or 0 if no line
+number is available. This information is useful for reporting
+application-level errors.

+
+scalar-value-list = scalar-value | scalar-value-list "," scalar-value
+
+array = "[" (scalar-value-list | empty) "]"
+
+list = "(" (value-list | empty) ")"
+
+group = "@{" (setting-list | empty) "@}"
+
