NAME

       cmark - convert CommonMark formatted text with GitHub Flavored Markdown extensions to HTML

SYNOPSIS

       cmark-gfm [options] file*

DESCRIPTION

       cmark-gfm  converts  Markdown  formatted  plain text to either HTML, groff man, CommonMark XML, LaTeX, or
       CommonMark, using the conventions described in the CommonMark spec.  It reads input  from  stdin  or  the
       specified files (concatenating their contents) and writes output to stdout.

OPTIONS

       --to, -t FORMAT
                   Specify output format (html, man, xml, latex, commonmark).

       --width WIDTH
                   Specify  a  column  width  to which to wrap the output. For no wrapping, use the value 0 (the
                   default).  This option currently only affects the commonmark, latex, and man renderers.

       --hardbreaks
                   Render soft breaks (newlines inside paragraphs in the CommonMark source) as hard line  breaks
                   in  the target format.  If this option is specified, hard wrapping is disabled for CommonMark
                   output, regardless of the value given with --width.

       --nobreaks  Render soft breaks as spaces.  If this option is specified, hard wrapping is disabled for all
                   output formats, regardless of the value given with --width.

       --sourcepos Include source position attribute.

       --normalize Consolidate adjacent text nodes.

       --extension, -e EXTENSION_NAME
                   Specify an extension name to use.

       --list-extensions
                   List available extensions and quit.

       --validate-utf8
                   Validate UTF-8, replacing illegal sequences with U+FFFD.

       --smart     Use  smart  punctuation.  Straight double and single quotes will be rendered as curly quotes,
                   depending on their position.  -- will be rendered as an en-dash.  --- will be rendered as  an
                   em-dash.  ... will be rendered as ellipses.

       --safe      Do not render raw HTML or potentially dangerous URLs.  (Raw HTML is replaced by a placeholder
                   comment; potentially dangerous URLs are replaced by empty strings.)  Dangerous URLs are those
                   that  begin  with  `javascript:`,  `vbscript:`,  `file:`, or `data:` (except for `image/png`,
                   `image/gif`, `image/jpeg`, or `image/webp` mime types).

       --help      Print usage information.

       --version   Print version.
