cmark - convert CommonMark formatted text to HTML
cmark 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.
- --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.
- --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
- Omit raw HTML and potentially dangerous URLs (default). Raw HTML is
replaced by a placeholder comment and potentially dangerous URLs are
replaced by empty strings. Potentially 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).
- --unsafe
- Render raw HTML or potentially dangerous URLs, overriding the default
(--safe) behavior.
- --help
- Print usage information.
- --version
- Print version.
