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.

       --unsafe    Render raw HTML and potentially dangerous URLs.  (Raw HTML is not replaced  by
                   a  placeholder  comment;  potentially dangerous URLs are not 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.
