Man-db is an implementation of the standard Unix documentation system accessed using the man command. It uses a Berkeley DB database in place of the traditional flat-text whatis databases.

This package provides traditional Unix "man pages" documenting the Linux kernel and C library interfaces employed by user-space programs.

Txt2man converts flat ASCII text to man page format.

XMLtoMan and XMLMantoHTML are two small scripts to convert xml to man pages in groff format or html. It features the usual man page items such as description, options, see also, etc.

mandoc is a suite of tools compiling mdoc, the roff macro language of choice for BSD manual pages, and man, the predominant historical language for UNIX manuals. It is small and quite fast. The main component of the toolset is the mandoc utility program, based on the libmandoc validating compiler, to format output for UTF-8 and ASCII UNIX terminals, HTML 5, PostScript, and PDF. Additional tools include the man viewer, and apropos and whatis.

scdoc is a simple man page generator written for POSIX systems in C99.

libpipeline is a C library for manipulating pipelines of subprocesses in a flexible and convenient way.

This package is a fork of cmark, with GitHub-specific Markdown additions.

frundis is a tool for compiling documents written in the frundis language, a semantic markup language primarily intended for supporting authoring of novels, but also well suited for many other kinds of documents. The frundis tool can export documents to LaTeX, XHTML 5, EPUB, markdown and groff mom.

The language has a focus on simplicity. It provides a few flexible built-in macros with extensible semantics. It strives to provide good error messages and catch typos, while still allowing one to finely control output for a specific format when needed.

Discount is a markdown implementation, written in C. It provides a markdown command, and a library.

MDVIEW MTX is a graphical Markdown viewer and CLI converter supporting the CommonMark specification. Features include page and directory search, document and link navigation, hotkeys, and one-click export to web browser.

Text::Markdown::Discount is a Perl extension to the Discount markdown implementation.

  use Text::Markdown::Discount;
  my $html = markdown($text)

Smu is a very simple and minimal markup language. It is designed for using in wiki-like environments. Smu makes it very easy to write your documents on the fly and convert them into HTML. Smu is capable to parse very large documents. As long as you avoid an huge amount of indents it scales just great.

Smu was started as a rewrite of Markdown but became something more lightweight and consistent. The biggest difference between Markdown and smu is that smu doesn't support reference style links.

This package provides a minimal set of Python bindings for the GitHub cmark fork (cmark-gfm).

Hoedown is a standards compliant, fast, secure markdown processing library written in C.

CommonMark is a strongly defined, highly compatible specification of Markdown. cmark is the C reference implementation of CommonMark. It provides the libcmark shared library for parsing CommonMark to an abstract syntax tree (AST) and rendering the document as HTML, groff man, LaTeX, CommonMark, or an XML representation of the AST. It also provides the command-line program cmark for parsing and rendering CommonMark.

Discount is a markdown implementation, written in C. It provides a markdown command, and a library.

MD4C is a C Markdown parser with a SAX-like interface. It is compliant to the CommonMark specification, with a few extensions.

This package provides a LaTeX converter, with the following goals:

• Faithful emulation of TEX’s behaviour;

• Easily extensible;

• Lossless, preserving both semantic and presentation cues;

• Use an abstract LATEX-like, extensible, document type;

• Infer the semantics of mathematical content

This package provides markdownify a Python library to convert HTML to Markdown.

Lowdown is a Markdown translator producing HTML5, roff documents in the ms and man formats, LaTeX, gemini, and terminal output.

This module is an XS wrapper around the official CommonMark C library libcmark. It closely follows the original API.

Markdown is a text-to-HTML conversion tool for web writers. It allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).

The mistletoe Markdown parser is a CommonMark-compliant Markdown parser that supports definitions of custom tokens.

Parsing Markdown into an abstract syntax tree also allows mistletoe to swap out renderers for different output formats, without touching any of the core components.
