### Footnotes extension
The Footnote extension implements [PHP Markdown Extra: Footnotes](https://michelf.ca/projects/php-markdown/extra/#footnotes).
This extension has some options:
| Functional option | Type | Description |
| ----------------- | ---- | ----------- |
| `extension.WithFootnoteIDPrefix` | `[]byte` | a prefix for the id attributes.|
| `extension.WithFootnoteIDPrefixFunction` | `func(gast.Node) []byte` | a function that determines the id attribute for given Node.|
| `extension.WithFootnoteLinkTitle` | `[]byte` | an optional title attribute for footnote links.|
| `extension.WithFootnoteBacklinkTitle` | `[]byte` | an optional title attribute for footnote backlinks. |
| `extension.WithFootnoteLinkClass` | `[]byte` | a class for footnote links. This defaults to `footnote-ref`. |
| `extension.WithFootnoteBacklinkClass` | `[]byte` | a class for footnote backlinks. This defaults to `footnote-backref`. |
| `extension.WithFootnoteBacklinkHTML` | `[]byte` | a class for footnote backlinks. This defaults to `&#x21a9;&#xfe0e;`. |
Some options can have special substitutions. Occurances of “^^” in the string will be replaced by the corresponding footnote number in the HTML output. Occurances of “%%” will be replaced by a number for the reference (footnotes can have multiple references).
`extension.WithFootnoteIDPrefix` and `extension.WithFootnoteIDPrefixFunction` are useful if you have multiple Markdown documents displayed inside one HTML document to avoid footnote ids to clash each other.
`extension.WithFootnoteIDPrefix` sets fixed id prefix, so you may write codes like the following:
```go
for _, path := range files {
source := readAll(path)
prefix := getPrefix(path)
markdown := goldmark.New(
goldmark.WithExtensions(
NewFootnote(
WithFootnoteIDPrefix([]byte(path)),
),
),
)
var b bytes.Buffer
err := markdown.Convert(source, &b)
if err != nil {
t.Error(err.Error())
}
}
```
`extension.WithFootnoteIDPrefixFunction` determines an id prefix by calling given function, so you may write codes like the following:
```go
markdown := goldmark.New(
goldmark.WithExtensions(
NewFootnote(
WithFootnoteIDPrefixFunction(func(n gast.Node) []byte {
v, ok := n.OwnerDocument().Meta()["footnote-prefix"]
if ok {
return util.StringToReadOnlyBytes(v.(string))
}
return nil
}),
),
),
)
for _, path := range files {
source := readAll(path)
var b bytes.Buffer
doc := markdown.Parser().Parse(text.NewReader(source))
doc.Meta()["footnote-prefix"] = getPrefix(path)
err := markdown.Renderer().Render(&b, source, doc)
}
```
You can use [goldmark-meta](https://github.com/yuin/goldmark-meta) to define a id prefix in the markdown document:
```markdown
---
title: document title
slug: article1
footnote-prefix: article1
---
# My article
```
