Add support for Bluesky

[rxu]

Add Bluesky to keep in sync with the latest text-formatter code. Possible yaml:

name: Bluesky
host: bsky.app
homepage: https://bsky.app/
example: https://bsky.app/profile/jamesgunn.bsky.social/post/3l6kscjixz22q
extract: "!bsky\\.app/profile/(?'name'[A-Za-z0-9.]+)/post/(?'id'\\w+)!"
oembed:
    endpoint: https://embed.bsky.app/oembed
    scheme: [https://bsky.app/profile/{@name}/post/{@id](https://bsky.app/profile/%7B@name%7D/post/%7B@id)}
scrape:
    - extract: "!\"did\":\\s*\"did:(?'did'[a-zA-Z0-9._:%-]+)\"!"
    - match: "//"
    - url: https://public.api.bsky.app/xrpc/app.bsky.actor.getProfile?actor={@name}
iframe:
    width: "550"
    height: "350"
    src: [https://embed.bsky.app/embed/did:{@did}/app.bsky.feed.post/{@id](https://embed.bsky.app/embed/did:%7B@did%7D/app.bsky.feed.post/%7B@id)}

Or alternatively, exported from the latest text-formatter:

attributes:
  embedder:
    filterChain:
      - "#regexp(/^(?:[-\\w]*\\.)*bsky\\.app$/)"
    required: 1
  url:
    filterChain:
      - urldecode
      - "#regexp(/^at:\\/\\/[.:\\w]+\\/[.\\w]+\\/\\w+$/)"
    required: 1
example:
  - "https://bsky.app/profile/bsky.app/post/3kkrqzuydho2v"
  - "https://bsky.app/profile/bnewbold.net/post/3kxjq2auebs2f"
extract:
  - "#https://(?'embedder'[.\\w]+)/oembed.*?url=(?'url'[\\w%.]+)#"
helper: "s9e\\TextFormatter\\Plugins\\MediaEmbed\\Configurator\\SiteHelpers\\BlueskyHelper"
homepage: "https://bsky.app/"
host:
  - "bsky.app"
iframe:
  data-s9e-livepreview-ignore-attrs: style
  height: 600
  onload: "let c=new MessageChannel;c.port1.onmessage=e=>this.style.height=e.data+'px';this.contentWindow.postMessage('s9e:init','*',[c.port2])"
  src: "https://s9e.github.io/iframe/2/bluesky.min.html#<xsl:value-of select=\"@url\"/>#<xsl:value-of select=\"@embedder\"/>"
  width: 600
name: "Bluesky"
scrape:
  - extract:
      - "#https://(?'embedder'[.\\w]+)/oembed.*?url=(?'url'[\\w%.]+)#"
    match:
      - "#/profile/[^/]+/post/.#"
source: "https://embed.bsky.app/"

Both don't work. The latter produces error like Fatal error: Uncaught RuntimeException: Regexp filter is missing a 'regexp' value in ....

Adding this code to the listener allows to go beyond the error

            if ($siteId == 'bluesky')
            {
                $hosts = array_keys(
                    (array) ($event['configurator']->registeredVars['MediaEmbed.hosts'] ?? []),
                    $siteId,
                    true
                );
                $event['configurator']->tags[$siteId]->attributes['embedder']->filterChain[0]->setRegexp(
                    '/^(?:[-\w]*\.)*' . $this->builder->build($hosts) . '$/'
                );
                $event['configurator']->tags[$siteId]->attributes['embedder']->required = 1;
                $event['configurator']->tags[$siteId]->attributes['url']->filterChain[0] = 'urldecode';
                $event['configurator']->tags[$siteId]->attributes['url']->filterChain[1]->setRegexp(
                    '/^at:\\/\\/[.:\\w]+\\/[.\\w]+\\/\\w+' . $this->builder->build($hosts) . '$/'
                );
                $event['configurator']->tags[$siteId]->attributes['url']->required = 1;
            }

But then another one: Fatal error: Uncaught ArgumentCountError: Too few arguments to function s9e\TextFormatter\Parser\AttributeFilters\RegexpFilter::filter(), 1 passed and exactly 2 expected

Yeah, it seems that version doesn't support custom regexps in site definitions. You could set the regexp manually after adding the site, or just remove it altogether since the library doesn't consider it unsafe.

$configurator = new s9e\TextFormatter\Configurator;

$siteConfig = json_decode(<<<'JSON'
    {
        "attributes":{
            "embedder":{
                "filterChain":[
                ],
                "required":true
            },
            "url":{
                "filterChain":[
                    "urldecode"
                ],
                "required":true
            }
        },
        "example":[

            "https:\/\/bsky.app\/profile\/jamesgunn.bsky.social\/post\/3l6kscjixz22q"
        ],
        "extract":[
            "#https:\/\/(?'embedder'[.\\w]+)\/oembed.*?url=(?'url'[\\w%.]+)#"
        ],
        "helper":"s9e\\TextFormatter\\Plugins\\MediaEmbed\\Configurator\\SiteHelpers\\BlueskyHelper",
        "homepage":"https:\/\/bsky.app\/",
        "host":[
            "bsky.app"
        ],
        "iframe":{
            "data-s9e-livepreview-ignore-attrs":"style",
            "height":600,
            "onload":"let c=new MessageChannel;c.port1.onmessage=e=>this.style.height=e.data+'px';this.contentWindow.postMessage('s9e:init','*',[c.port2])",

                ],
                "match":[
                    "#\/profile\/[^\/]+\/post\/.#"
                ]
            }
        ],
        "source":"https:\/\/embed.bsky.app\/",
        "tags":[
            "social"
        ]
    }
JSON, true);

$configurator->MediaEmbed->add('bluesky', $siteConfig);

extract($configurator->finalize());

$text = 'https://bsky.app/profile/bsky.app/post/3kkrqzuydho2v';
$xml  = $parser->parse($text);
$html = $renderer->render($xml);

die("$html\n");

Thanks for the hint. With this code

attributes:
    embedder:
        required: true
    url:
        required: true
example:
    - "https://bsky.app/profile/bsky.app/post/3kkrqzuydho2v"
    - "https://bsky.app/profile/bnewbold.net/post/3kxjq2auebs2f"
extract: "#https://(?'embedder'[.\\w]+)/oembed.*?url=(?'url'[\\w%.]+)#"
homepage: "https://bsky.app/"

there're no errors, but example URLs don't load (loads ok directly in a browser).

The relevant source code is (looks like the iframe's body is empty):

<div class="content"><iframe data-s9e-mediaembed="bluesky" allowfullscreen="" loading="lazy" onload="let c=new MessageChannel;c.port1.onmessage=e=>this.style.height=e.data+'px';this.contentWindow.postMessage('s9e:init','*',[c.port2])" scrolling="no" src="https://s9e.github.io/iframe/2/bluesky.min.html#at%3A%2F%2Fdid%3Aplc%3A44ybard66vv44zksje25o7dz%2Fapp.bsky.feed.post%2F3kxjq2auebs2f#embed.bsky.app" style="border:0;height:600px;max-width:600px;width:100%"></iframe></div>
