NAME

Bluesky - Bluesky Client Library in Perl

SYNOPSIS

use Bluesky;
my $bsky = Bluesky->new();
$bsky->login( 'sanko', '1111-2222-3333-4444' );
$bsky->createPost( ... );
# To be continued...

DESCRIPTION

You shouldn't need to know the AT protocol in order to get things done so I'm including this sugary wrapper so that At can remain mostly technical.

Methods

Bluesky.pm is my attempt to make use of Perl's class syntax so this is obviously OO.

new( ... )

my $bsky = Bluesky->new( 'sanko', '1111-2222-3333-4444' );

Expected parameters include:

identifier - required

Handle or other identifier supported by the server for the authenticating user.

password - required

This is the app password not the account's password. App passwords are generated at https://bsky.app/settings/app-passwords.

getTimeline( [...] )

$bsky->getTimeline();

Get a view of the requesting account's home timeline. This is expected to be some form of reverse-chronological feed.

Expected parameters include:

algorithm

Variant 'algorithm' for timeline. Implementation-specific.

NOTE: most feed flexibility has been moved to feed generator mechanism.

limit

Integer.

Default: 50, Minimum: 1, Maximum: 100.

cursor

getAuthorFeed( ... )

$bsky->getAuthorFeed( actor => 'sankor.bsky.social' );

Get a view of an actor's 'author feed' (post and reposts by the author).

Expected parameters include:

actor - required

AT-identifier for the author.

limit

Integer.

Default: 50, Minimum: 1, Maximum: 100.

cursor
filter

Combinations of post/repost types to include in response.

Known values:

posts_with_replies - default
posts_no_replies
posts_with_media
posts_and_author_threads
includePins

Boolean value (false is default).

An error is returned if the client is blocked by the actor.

getPostThread( ... )

$bsky->getPostThread( uri => 'at://bsky.app/app.bsky.feed.post/3l6oveex3ii2l' );

Get posts in a thread. Does not require auth, but additional metadata and filtering will be applied for authed requests.

Expected parameters include:

uri - required

Reference (AT-URI) to post record.

depth

How many levels of reply depth should be included in response.

Default: 6, Minimum: 0, Maximum: 1000.

parentHeight

How many levels of parent (and grandparent, etc) post to include.

Default: 80, Minimum: 0, Maximum: 1000.

Returns an error if the thread cannot be found.

getPost( ... )

$bsky->getPost('at://did:plc:z72i7hdynmk6r22z27h6tvur/app.bsky.feed.post/3l6oveex3ii2');

Gets a single post view for a specified post (by AT-URI).

Expected parameters include:

uri - required

AT-URI.

getPosts( ... )

$bsky->getPosts(
    'at://did:plc:z72i7hdynmk6r22z27h6tvur/app.bsky.feed.post/3l6oveex3ii2l',
    'at://did:plc:z72i7hdynmk6r22z27h6tvur/app.bsky.feed.post/3lbvgvbvcf22c'
);

Gets post views for a specified list of posts (by AT-URI). This is sometimes referred to as 'hydrating' a 'feed skeleton'.

Expected parameters include:

uris - required

List of (up to 25) post AT-URIs to return hydrated views for.

getLikes( ... )

$bsky->getLikes( uri => 'at://did:plc:z72i7hdynmk6r22z27h6tvur/app.bsky.feed.post/3l6oveex3ii2l' );

Get like records which reference a subject (by AT-URI and CID).

Expected parameters include:

uri - required

AT-URI of the subject (eg, a post record).

cid

CID of the subject record (aka, specific version of record), to filter likes.

limit

Integer.

Default: 50, Minimum: 1, Maximum: 100.

cursor

createPost( ... )

$bsky->createPost( text => 'Test. Test. Test.' );

Create a new post.

Expected parameters include:

text - required

The primary post content. May be an empty string, if there are embeds.

Annotations of text (mentions, URLs, hashtags, etc) are automatically parsed. These include:

mentions

Facet feature for mention of another account. The text is usually a handle, including a '@' prefix, but the facet reference is a DID.

This is an example. Here, I am mentioning @atproto.bsky.social and it links to their profile.

Facet feature for a URL. The text URL may have been simplified or truncated, but the facet reference should be a complete URL.

This is an example that would link to Google here: https://google.com/.
tags

Facet feature for a hashtag. The text usually includes a '#' prefix, but the facet reference should not (except in the case of 'double hash tags').

This is an example that would link to a few hashtags. #perl #atproto
timestamp

Client-declared timestamp (ISO 8601 in UTC) when this post was originally created.

Defaults to the current time.

lang

Indicates human language of post primary text content.

$bsky->createPost(
    lang     => [ 'en', 'ja' ],
    reply_to => 'at://did:plc:pwqewimhd3rxc4hg6ztwrcyj/app.bsky.feed.post/3lbvllq2kul27',
    text     => 'こんにちは, World!'
);

This is expected to be a comma separated string of language codes (e.g. en-US,en;q=0.9,fr).

Bluesky recommends sending the Accept-Language header to get posts in the user's preferred language. See https://www.w3.org/International/questions/qa-lang-priorities.en and https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry.

reply_to

AT-URL of a post to reply to.

$bsky->createPost( reply_to => 'at://did:plc:pwqewimhd3rxc4hg6ztwrcyj/app.bsky.feed.post/3lbvllq2kul27', text => 'Exactly!' );
embed

Bluesky allows for posts to contain embedded data.

Known embed types:

images

Up to 4 images (path name or raw data).

Set alt text by passing a hash.

$bsky->createPost(
    embed    => { images => ['path/to/my.jpg'] },
    lang     => 'en',
    reply_to => 'at://did:plc:pwqewimhd3rxc4hg6ztwrcyj/app.bsky.feed.post/3lbvllq2kul27',
    text     => 'I found this image on https://google.com/'
);

$bsky->createPost(
    embed    => { images => [{ alt => 'Might be a picture of a frog.', image => 'path/to/my.jpg' }] },
    lang     => 'en',
    reply_to => 'at://did:plc:pwqewimhd3rxc4hg6ztwrcyj/app.bsky.feed.post/3lbvllq2kul27',
    text     => 'I found this image on https://google.com/'
);
url

A card (including the URL, the page title, and a description) will be presented in a GUI.

$bsky->createPost( embed => { url => 'https://en.wikipedia.org/wiki/Main_Page' }, text => <<'END');
This is the link to wikipedia, @atproto.bsky.social. You should check it out.
END
ref

An AT-URL to link from this post.

video

A video to be embedded in a Bluesky record (eg, a post).

$bsky->createPost( embed => { video => 'path/to/cat.mpeg' }, text => 'Loot at this little guy!' );

This might be a single path, raw data, or a hash reference (if you're really into what and how the video is presented).

If passed a hash, the following are expected:

video - required

The path name.

alt

Alt text description of the video, for accessibility.

mime

Mime type.

We try to figure this out internally if undefined.

aspectRatio

Represents an aspect ratio.

It may be approximate, and may not correspond to absolute dimensions in any given unit.

...
aspectRatio =>{ width => 100, height => 120 },
...
captions

This is a hash reference of up to 20 WebVTT files organized by language.

...
captions => {
    en => 'english.vtt',
    ja => 'japanese.vtt'
},
...

You may also pass your own valid embed.

labels

Self-label values for this post. Effectively content warnings.

tags

Additional hashtags, in addition to any included in post text and facets.

These are not visible in the current Bluesky interface but do cause posts to return as results to to search (such as https://bsky.app/hashtag/perl.

Note that a post may only contain one of the following embeds: image, video, embed_url, or embed_ref.

deletePost( ... )

$bsky->deletePost( 'at://did:plc:pwqewimhd3rxc4hg6ztwrcyj/app.bsky.feed.post/3lcdwvquo7y25' );

my $post = $bsky->createPost( ... );
...
$bsky->deletePost( $post->{uri} );

Delete a post or ensures it doesn't exist.

Expected parameters include:

uri - required
