markdown-it-footnote.rs

A markdown-it.rs plugin to process footnotes.

It is based on the pandoc definition:

Normal footnote:

Here is a footnote reference,[^1] and another.[^longnote]

Here is an inline note.^[my note is here!]

[^1]: Here is the footnote.

[^longnote]: Here's one with multiple blocks.

    Subsequent paragraphs are indented to show that they
belong to the previous footnote.

See the tests for more examples.

Usage

To load the full plugin:

let parser = &mut markdown_it::MarkdownIt::new();
markdown_it::plugins::cmark::add(parser);

md_footnote::add(parser);

let ast  = parser.parse("Example^[my note]");
let html = ast.render();

Alternatively, you can load the separate components:

let parser = &mut markdown_it::MarkdownIt::new();
markdown_it::plugins::cmark::add(parser);

md_footnote::definitions::add(md);
md_footnote::references::add(md);
md_footnote::inline::add(md);
md_footnote::collect::add(md);
md_footnote::back_refs::add(md);

Which have the following roles:

• definitions: parse footnote definitions, e.g. [^1]: foo
• references: parse footnote references, e.g. [^1]
• inline: parse inline footnotes, e.g. ^[foo]
• collect: collect footnote definitions (removing duplicate/unreferenced ones) and move them to be the last child of the root node.
• back_refs: add anchor(s) to footnote definitions, with links back to the reference(s)
