/*
Package gorilla/css/scanner generates tokens for a CSS3 input.
It follows the CSS3 specification located at:
http://www.w3.org/TR/css3-syntax/
To use it, create a new scanner for a given CSS string and call Next() until
the token returned has type TokenEOF or TokenError:
s := scanner.New(myCSS)
for {
token := s.Next()
if token.Type == scanner.TokenEOF || token.Type == scanner.TokenError {
break
}
// Do something with the token...
}
Following the CSS3 specification, an error can only occur when the scanner
finds an unclosed quote or unclosed comment. In these cases the text becomes
"untokenizable". Everything else is tokenizable and it is up to a parser
to make sense of the token stream (or ignore nonsensical token sequences).
Note: the scanner doesn't perform lexical analysis or, in other words, it
doesn't care about the token context. It is intended to be used by a
lexer or parser.

### Inline CSS
Although it's possible to handle inline CSS using `AllowAttrs` with a `Matching` rule, writing a single monolithic regular expression to safely process all inline CSS which you wish to allow is not a trivial task. Instead of attempting to do so, you can whitelist the `style` attribute on whichever element(s) you desire and use style policies to control and sanitize inline styles.
It is suggested that you use `Matching` (with a suitable regular expression)
`MatchingEnum`, or `MatchingHandler` to ensure each style matches your needs,
but default handlers are supplied for most widely used styles.
Similar to attributes, you can allow specific CSS properties to be set inline:
```go
p.AllowAttrs("style").OnElements("span", "p")
// Allow the 'color' property with valid RGB(A) hex values only (on any element allowed a 'style' attribute)
p.AllowStyles("color").Matching(regexp.MustCompile("(?i)^#([0-9a-f]{3,4}|[0-9a-f]{6}|[0-9a-f]{8})$")).Globally()
```
Additionally, you can allow a CSS property to be set only to an allowed value:
```go
p.AllowAttrs("style").OnElements("span", "p")
// Allow the 'text-decoration' property to be set to 'underline', 'line-through' or 'none'
// on 'span' elements only
p.AllowStyles("text-decoration").MatchingEnum("underline", "line-through", "none").OnElements("span")
```
Or you can specify elements based on a regex patterm match:
```go
p.AllowAttrs("style").OnElementsMatching(regex.MustCompile(`^my-element-`))
// Allow the 'text-decoration' property to be set to 'underline', 'line-through' or 'none'
// on 'span' elements only
p.AllowStyles("text-decoration").MatchingEnum("underline", "line-through", "none").OnElementsMatching(regex.MustCompile(`^my-element-`))
```
If you need more specific checking, you can create a handler that takes in a string and returns a bool to
validate the values for a given property. The string parameter has been
converted to lowercase and unicode code points have been converted.
```go
myHandler := func(value string) bool{
return true
}
p.AllowAttrs("style").OnElements("span", "p")
// Allow the 'color' property with values validated by the handler (on any element allowed a 'style' attribute)
p.AllowStyles("color").MatchingHandler(myHandler).Globally()
```

## TODO
* Add support for CSS sanitisation to allow some CSS properties based on a whitelist, possibly using the [Gorilla CSS3 scanner](http://www.gorillatoolkit.org/pkg/css/scanner) - PRs welcome so long as testing covers XSS and demonstrates safety first
* Investigate whether devs want to blacklist elements and attributes. This would allow devs to take an existing policy (such as the `bluemonday.UGCPolicy()` ) that encapsulates 90% of what they're looking for but does more than they need, and to remove the extra things they do not want to make it 100% what they want
* Investigate whether devs want a validating HTML mode, in which the HTML elements are not just transformed into a balanced tree (every start tag has a closing tag at the correct depth) but also that elements and character data appear only in their allowed context (i.e. that a `table` element isn't a descendent of a `caption`, that `colgroup`, `thead`, `tbody`, `tfoot` and `tr` are permitted, and that character data is not permitted)

=========================
[![GoDev][godev-image]][godev-url]
[godev-image]: https://pkg.go.dev/badge/github.com/yuin/goldmark-emoji
[godev-url]: https://pkg.go.dev/github.com/yuin/goldmark-emoji
goldmark-emoji is an extension for the [goldmark](http://github.com/yuin/goldmark)
that parses `:joy:` style emojis.
Installation
--------------------
```
go get github.com/yuin/goldmark-emoji
```
Usage
--------------------
```go
import (
"bytes"
"fmt"
"github.com/yuin/goldmark"
"github.com/yuin/goldmark-emoji"
"github.com/yuin/goldmark-emoji/definition"
)
func main() {
markdown := goldmark.New(
goldmark.WithExtensions(
emoji.Emoji,
),
)
source := `
Joy :joy:
`
var buf bytes.Buffer
if err := markdown.Convert([]byte(source), &buf); err != nil {
panic(err)
}
fmt.Print(buf.String())
}
```
See `emoji_test.go` for detailed usage.
### Options
Options for the extension
| Option | Description |
| ------ | ----------- |
| `WithEmojis` | Definition of emojis. This defaults to github emoji set |
| `WithRenderingMethod` | `Entity` : renders as HTML entities, `Twemoji` : renders as an img tag that uses [twemoji](https://github.com/twitter/twemoji), `Func` : renders using a go function |
| `WithTwemojiTemplate` | Twemoji img tag printf template |
| `WithRendererFunc` | renders by a go function |

### 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
```
