Templating

The field value is null, or a MarkdownData object:

{{ entry.body.html }}   {# the parsed HTML #}
{{ entry.body.raw }}    {# the raw Markdown, as typed #}
{{ entry.body.text }}   {# parsed, then stripped to plain text #}
{{ entry.body.flavour }} {# the flavour it was parsed with #}

{{ entry.body }} on its own outputs the raw Markdown, so Craft’s own filter still works if you’d rather parse it yourself:

{{ entry.body|md('gfm') }}
{{ entry.body|md(inlineOnly=true) }}

For Markdown that isn’t in a Markdown field, whether a plain text field, a plugin setting, or a string you built in the template, |marky parses it the way the field does: reference tags resolved, HTML purified.

{{ entry.summary|marky }}
{{ entry.summary|marky(flavour='original') }}
{{ entry.summary|marky(refs=false, purify=false) }}

Arguments are flavour, refs, purify, purifierConfig and siteId, all optional.

Craft’s |md is untouched and still the right choice when plain Markdown parsing is all you want. The difference is what each one does beyond parsing:

Piping a field value, {{ entry.body|marky }}, is the same as {{ entry.body.html }}, since it takes the field’s own settings. It’s worth doing only to override one of them for a single render:

{{ entry.body|marky(refs=false) }}

Empty fields are null, so the usual guard applies:

{% if entry.body %}
    {{ entry.body.html }}
{% endif %}
