NAME

Markdown::Parser::Footnote - Markdown Footnote Element

SYNOPSIS

my $o = Markdown::Parser::Footnote->new;
# or
$doc->add_element( $o->create_footnote( @_ ) );

VERSION

v0.2.0

DESCRIPTION

This class represents a footnote. It is used by Markdown::Parser and inherits from Markdown::Parser::Element

This is an extension of the original Markdown.

To quote from Markdown Guide:

Footnotes allow you to add notes and references without cluttering the body of the document. When you create a footnote, a superscript number with a link appears where you added the footnote reference. Readers can click the link to jump to the content of the footnote at the bottom of the page.

To create a footnote reference, add a caret and an identifier inside brackets ([^1]). Identifiers can be numbers or words, but they can’t contain spaces or tabs. Identifiers only correlate the footnote reference with the footnote itself — in the output, footnotes are numbered sequentially.

Add the footnote using another caret and number inside brackets with a colon and text ([^1]: My footnote.). You don’t have to put footnotes at the end of the document. You can put them anywhere except inside other elements like lists, block quotes, and tables.

Here's a simple footnote,[^1] and here's a longer one.[^bignote]

[^1]: This is the first footnote.

[^bignote]: Here's one with multiple paragraphs and code.

    Indent paragraphs to include them in the footnote.

    `{ my code }`

    Add as many paragraphs as you like.

The rendered output looks like this:

Here’s a simple footnote,1 and here’s a longer one.2

    1. This is the first footnote. ↩

    2. Here’s one with multiple paragraphs and code.

       Indent paragraphs to include them in the footnote.

       { my code }

       Add as many paragraphs as you like. ↩

Inline Footnotes

For consistency with links, footnotes can be added inline, like this:

I met Jack [^jack](Co-founder of Angels, Inc) at the meet-up.

Inline notes will work even without the identifier. For example:

I met Jack [^](Co-founder of Angels, Inc) at the meet-up.

However, in compliance with pandoc footnotes style, inline footnotes can also be added like this:

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.]

The footnote id of inline notes will be auto-generated

Footnotes will appear at the end of the document in their order of appearance.
