<h4>What is tidy ?</h4>

-  \ref tidylib 
        - is a C static or dynamic library that developers can integrate into their applications 
          in order to bring all of Tidy’s power to your favorite tools. 
        - `tidylib` is used today in desktop applications, web servers, and more.
        
-  \ref tidy5_cmd 
        - is a console application built on \ref tidylib for Mac OS X, Linux, Windows, UNIX, and more. 
        - It corrects and cleans up HTML and XML documents by fixing markup errors and upgrading legacy code to modern standards.

- \b TidyLib - is easy to integrate. Because of the near universal adoption of C linkage, a C interface may be called from a great number of programming languages.

- \b TidyLib - is designed to use opaque types in the public interface. This allows the application to just pass an integer around and the need to transform data types in different languages is minimized. As a results it’s straight-forward to write very thin library wrappers for C++, Pascal, and COM/ATL.

- \b TidyLib - eats its own dogfood. HTML Tidy links directly to TidyLib.

- \b TidyLib - is Thread Safe and Re-entrant. Because there are many uses for HTML Tidy - from content validation, content scraping, conversion to XHTML - it was important to make TidyLib run reasonably well within server applications as well as client side.

- \b TidyLib - uses adaptable I/O. As part of the larger integration strategy it was decided to fully abstract all I/O. This means a (relatively) clean separation between character encoding processing and shovelling bytes back and forth. Internally, the library reads from sources and writes to sinks. This abstraction is used for both markup and configuration “files”. Concrete implementations are provided for file and memory I/O, and new sources and sinks may be provided via the public interface.

\section Prerequisites

 - \b git - <a href="http://git-scm.com/book/en/v2/Getting-Started-Installing-Git">git-scm.com/book/en/v2/Getting-Started-Installing-Git</a>
 - \b cmake - <a href="http://www.cmake.org/download/">cmake.org/download/</a>
 - Appropriate build tools for the platform

CMake comes in two forms - command line and gui. Some installations only install one or the other, but sometimes both. The build 
commands below are only for the command line use.

Also the actual build tools vary for each platform. But that is one of the great features of cmake, it can generate 
variuous 'native' build files. Running cmake without any parameters will list the generators 
available on that platform. For sure one of the common ones is "Unix Makefiles", which needs autotools 
make installed, but many other generators are supported.

In windows cmake offers various versions of MSVC. Again below only the command line use of MSVC is shown, but the 
tidy solution (*.sln) file can be loaded into the MSVC IDE, and the building done in there.

\section get_source Get the source code

Tidy’s sourcecode can be found at <a href="https://github.com/htacg/tidy-html5">github.com/htacg/tidy-html5</a>. There are sometimes 
several branches, but in general `master` is the most recently updated version. 

\note Note that as “cutting edge,” it may have bugs or other 
unstable behavior. If you prefer a stable, officially released version, be sure to have a look 
at Releases on the github page.

In general you can use the <b>Download ZIP</b> button on the github page to download the most recent version of a branch. If you prefer 
Git then you can  clone the repository to a working machine with:


\code{.sh}
git clone git@github.com:htacg/tidy-html5.git
\endcode

\section compile Compile

<h4>Enter the `build/cmake` directory</h4>
\code{.sh}
# *nix
cd {your-tidy-html5-directory}/build/cmake

# windows
cd {your-tidy-html5-directory}\build\cmake
\endcode

<h4>Configure the build</h4>
\code{.sh}
# *nix
cmake ../../ [-DCMAKE_INSTALL_PREFIX=/path/for/install]

# windows
cmake ..\..\ 
\endcode
By default cmake sets the install path to `/usr/local` in unix. 

If you wanted the binary in say `/usr/bin` instead, then use `-DCMAKE_INSTALL_PREFIX=/usr`

On windows the default install is to `C:\Program Files\tidy5`, or `C:/Program Files (x86)/tidy5`, which is not very useful. After 
the build the `tidy[n].exe` is in the `Release\` directory, and can be copied to any directory in your `PATH` environment variable, for global use.

If you need the tidy library built as a 'shared' (DLL) library, then in add the command `-DBUILD_SHARED_LIB:BOOL=ON`. 
This option is `OFF` by default, so the static library is built and linked with the command line tool for convenience.


<h4>Compile</h4>
\code{.sh}
# *nix
make

# windows
cmake --build . --config Release
\endcode

<h4>Install</h4>
\code{.sh}
# *nix
[sudo] make install

# windows
cmake --build . --config Release --target INSTALL
\endcode


\page history History

- This repository originally transferred from w3c.github.com/tidy-html5.

- First moved to <a href="https://github.com/htacg/tidy-html5">Github</a> from <a href="http://tidy.sourceforge.net/">tidy.sourceforge.net</a>


<p><strong>HTML Tidy</strong> was created by the <a href="http://www.w3.org/">W3C’s</a> own  <a href="http://www.w3.org/People/Raggett/">Dave Raggett</a> back in the
dawn of the Internet age. His original Internet page is still available and
gives a sense of the early history: <a href="http://www.w3.org/People/Raggett/tidy/">Clean up your Web pages with HTML TIDY</a>.</p>

<p>Satisfied with his work Dave passed the torch to a dedicated group of
maintainers at <a href="http://tidy.sourceforge.net/">tidy.sourceforge.net</a> where the important tasks of turning
<strong>Tidy</strong> into a C library and keeping up with developing standards was
performed.</p>

<p>W3C members took a renewed interest in <strong>Tidy</strong> in 2011 and forked the
project to <a href="https://github.com/w3c/tidy-html5">github</a> (now redirects to new maintainers), where it featured
compatibility with HTML5 via a <a href="https://lists.w3.org/Archives/Public/www-archive/2011Nov/0007.html">key contribution</a> from one of the SourceForge
key members.</p>

<p>In 2015 a group of concerned developers, users, and software integrators formed
<a href="http://www.htacg.org">HTACG</a> with the goal of revitalizing <strong>Tidy</strong>, which had fallen into a
non-maintained state. As a W3C Community Group, HTACG was deemed worthy by the
W3C, and W3C passed ownership of their project to HTACG, where it is currently
being developed and prepped for a new, stable, and modern release.</p>

<p>HTACG is also working diligently with the SourceForge maintainers in an effort
to harmonize <strong>HTML Tidy</strong> into a single, stable, solid release once again.</p>
