Footnotes

Footnotes allow readers to reference additional information without cluttering the main content.

Compact footnotes

Quarkdown introduces a compact [^label: definition] syntax that allows you to define footnotes directly at their reference point.

Example 1

This is a footnote reference[^first: This is the definition.],
and another one[^second: This is another definition.].

Named footnotes can be referenced multiple times.

Example 2

This is a footnote reference[^first: This is the definition],
and another one[^first].

Definitions can include inline formatting.

Example 3

This is a footnote reference[^first: This is the **definition**.]

Anonymous footnotes

When an inlined footnote does not need to be referenced elsewhere, you can omit the label to create an anonymous footnote.

This is a footnote reference[^: This is the definition.],
and another one[^: This is another definition.].

Standard footnotes

Quarkdown also supports the standard footnote syntax provided by many Markdown flavors.

This approach is more verbose but allows for a clean separation between the footnote reference and its definition, reducing clutter in the main text.

This is a footnote reference[^1].

[^1]: This is the definition.

Inline formatting is also supported in the definition:

[^1]: This is the **definition**.

Long definitions can span multiple lines. Indentation is not significant:

[^1]: This is
      the definition.

When you have multiple footnotes, separate the definitions with at least one blank line:

This is a footnote reference[^first], and another one[^second].

[^first]: This is the definition.

[^second]: This is another definition.

Multiple references to the same footnote label are allowed, and they all point to the same definition:

This is a footnote reference[^first], and another one[^first].

[^first]: This is the definition.

The footnote label can be any string, and the definition can appear anywhere in the document:

[^first]: This is the definition.

This is a footnote reference[^first], and another one[^second].

[^second]: This is another definition.

Numbering

Footnotes are numbered by default with decimal numbers, starting from 1. To apply a different numbering style, such as Roman numerals, use the .numbering function. See Numbering for more information.

Example 5

.numbering
    - footnotes: i

Footnotes are numbered incrementally across the subdocument. Page-level numbering is not supported yet.

Display

Footnotes render differently depending on the document type. See Document types for more information.
