Footnotes plugin for markdown-it markdown parser.

v2.+ requires markdown-it v5.+, see changelog.

Markup is based on pandoc definition.

Normal footnote:

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

[^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.

html:

<p>Here is a footnote reference,<sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup> and another.<sup class="footnote-ref"><a href="#fn2" id="fnref2">[2]</a></sup></p>
<p>This paragraph won’t be part of the note, because it
isn’t indented.</p>
<hr class="footnotes-sep">
<section class="footnotes">
<ol class="footnotes-list">
<li id="fn1"  class="footnote-item"><p>Here is the footnote. <a href="#fnref1" class="footnote-backref">↩</a></p>
</li>
<li id="fn2"  class="footnote-item"><p>Here’s one with multiple blocks.</p>
<p>Subsequent paragraphs are indented to show that they
belong to the previous footnote. <a href="#fnref2" class="footnote-backref">↩</a></p>
</li>
</ol>
</section>

Inline footnote:

Here is an inline note.^[Inlines notes are easier to write, since
you don't have to pick an identifier and move down to type the
note.]

html:

<p>Here is an inline note.<sup class="footnote-ref"><a href="#fn1" id="fnref1">[1]</a></sup></p>
<hr class="footnotes-sep">
<section class="footnotes">
<ol class="footnotes-list">
<li id="fn1"  class="footnote-item"><p>Inlines notes are easier to write, since
you don’t have to pick an identifier and move down to type the
note. <a href="#fnref1" class="footnote-backref">↩</a></p>
</li>
</ol>
</section>

Install

node.js, browser:

npm install markdown-it-footnote --save
bower install markdown-it-footnote --save

Use

var md = require('markdown-it')()
            .use(require('markdown-it-footnote'));

md.render(/*...*/) // See examples above

Differences in browser. If you load script directly into the page, without package system, module will add itself globally as window.markdownitFootnote.
