The universal markup converter
------------------------------

Pandoc is a [Haskell] library for converting from one markup format to
another, and a command-line tool that uses this library. It can read
[Markdown], [CommonMark], [PHP Markdown Extra], [GitHub-Flavored Markdown],
[MultiMarkdown], and (subsets of) [Textile], [reStructuredText], [HTML],
[LaTeX], [MediaWiki markup], [TWiki markup], [Haddock markup], [OPML], [Emacs
Org mode], [DocBook], [txt2tags], [EPUB], [ODT] and [Word docx]; and it can
write plain text, [Markdown], [CommonMark], [PHP Markdown Extra],
[GitHub-Flavored Markdown], [MultiMarkdown], [reStructuredText], [XHTML],
[HTML5], [LaTeX] \(including [`beamer`] slide shows\), [ConTeXt], [RTF], [OPML],
[DocBook], [OpenDocument], [ODT], [Word docx], [GNU Texinfo], [MediaWiki
markup], [DokuWiki markup], [ZimWiki markup], [Haddock markup],
[EPUB] \(v2 or v3\), [FictionBook2], [Textile], [groff man] pages,
[Emacs Org mode], [AsciiDoc], [InDesign ICML], [TEI Simple], and [Slidy],
[Slideous], [DZSlides], [reveal.js] or [S5] HTML slide shows. It can also
produce [PDF] output on systems where LaTeX, ConTeXt, or `wkhtmltopdf` is
installed.

Pandoc's enhanced version of Markdown includes syntax for [footnotes],
[tables], flexible [ordered lists], [definition lists], [fenced code blocks],
[superscripts and subscripts], [strikeout], [metadata blocks], automatic tables of
contents, embedded LaTeX [math], [citations], and [Markdown inside HTML block
elements]. (These enhancements, described
further under [Pandoc's Markdown], can be disabled using the
`markdown_strict` input or output format.)

In contrast to most existing tools for converting Markdown to HTML, which
use regex substitutions, pandoc has a modular design: it consists of a
set of readers, which parse text in a given format and produce a native
representation of the document, and a set of writers, which convert
this native representation into a target format. Thus, adding an input
or output format requires only adding a reader or writer.

Because pandoc's intermediate representation of a document is less
expressive than many of the formats it converts between, one should
not expect perfect conversions between every format and every other.
Pandoc attempts to preserve the structural elements of a document, but
not formatting details such as margin size.  And some document elements,
such as complex tables, may not fit into pandoc's simple document
model.  While conversions from pandoc's Markdown to all formats aspire
to be perfect, conversions from formats more expressive than pandoc's
Markdown can be expected to be lossy.
