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.
