Footnotes

Footnotes are defined with {{{#fn ...}}} blocks.

Core Behavior

1. {{{#fn ...}}} inserts an inline footnote marker and stores the footnote content.
2. [fn] renders the currently collected footnotes at that position and clears the pending list.
3. If [fn] is not used, remaining footnotes are rendered automatically at the end of the document.

Basic Usage

This sentence has a note{{{#fn First footnote content. }}}.
Another sentence{{{#fn Second footnote content. }}}.

[fn]

Default End-of-Document Rendering

Paragraph A{{{#fn Footnote A }}}.
Paragraph B{{{#fn Footnote B }}}.

// No [fn] macro here
// -> Footnotes render at the document end

Custom Marker Text (#display)

Use #display when you want a custom marker label instead of the numeric index.

Main text{{{#fn #display="*" Custom marker footnote. }}}.

Named Footnotes (#name)

Use #name to create a reusable named footnote. The first occurrence defines the footnote, and later occurrences with the same name link back to the original entry.

API limits{{{#fn #name="rate-limit" Requests are limited to 100 per minute. }}}.
See also{{{#fn #name="rate-limit" Later named references point back to the first definition. }}}.

[fn]

Notes about named footnotes:

• The rendered marker text uses the #name value.
• Later definitions with the same #name become references only; their content is not added again.
• Named footnotes stay globally addressable across multiple [fn] flushes within the same render pass.

Rich Content in Footnotes

Footnote content can contain other SevenMark elements:

Code: {{{#code #lang="rust"
println!("hi");
}}}
}}}.

Mid-document Footnote Section

You can place [fn] to flush footnotes at a specific location.

Intro text{{{#fn Intro note }}}.

Restrictions

• Nested footnote definitions are not allowed ({{{#fn ... {{{#fn ...}}} ...}}}).
• [fn] is a footnote-list macro, not an inline reference marker.
• Parameter keys may contain letters, digits, underscores, and hyphens.

Notes

• Numbering follows the order of unnamed {{{#fn}}} definitions in the document.
• Using [fn] multiple times is supported; each call flushes only the footnotes collected so far.
