title: HTML Tidy Extension prev_title: CodeHilite Extension prev_url: code_hilite.html next_title: HeaderId Extension next_url: header_id.html HTML Tidy ========= Runs [HTML Tidy][] on the output of Python-Markdown using the [uTidylib][] Python wrapper. Both libtidy and uTidylib must be installed on your system. This extension is available in the standard Markdown library since version 2.0. [HTML Tidy]: http://tidy.sourceforge.net/ [uTidylib]: http://utidylib.berlios.de/ Note than any Tidy [options][] can be passed in as [extension configs][]. So, for example, to output HTML rather than XHTML, set ``output_xhtml=0``. To indent the output, set ``indent=auto`` and to have Tidy wrap the output in ``<html>`` and ``<body>`` tags, set ``show_body_only=0``. See Tidy's [options][] for a full list of the available options. The defaults are set to most closely match Markdowns defaults with the exception that you get much better pretty-printing. [options]: http://tidy.sourceforge.net/docs/quickref.html [extension configs]: ../reference.html#extension_configs Note that options set in this extension will override most any other settings passed on to Markdown (such as "output_format"). Unlike Markdown, this extension will also treat raw HTML no different than that output by Markdown. In other words, it may munge a document authors carefully crafted HTML. Of course, it may also transform poorly formed raw HTML into nice, valid HTML. Take these things into consideration when electing to use this extension.
