SYNOPSIS

  use Mastodon::Client;

  my $client = Mastodon::Client->new(
    instance        => 'mastodon.social',
    name            => 'PerlBot',

  );

DESCRIPTION

Mastodon::Client lets you talk to a Mastodon server.

This distribution is still in development, and the interface might change in the future. But changes should mostly be to add convenience methods for the more common tasks.

The use of the request methods (post, get, etc) is not likely to change, and as long as you know the endpoints you are reaching, this should be usable right now.

ATTRIBUTES

instance

A Mastodon::Entity::Instance object representing the instance to which this client will speak. Defaults to mastodon.social.

api_version

An integer specifying the version of the API endpoints to use. Defaults to 1.

redirect_uri

The URI to which authorization codes should be forwarded as part of the OAuth2 flow. Defaults to urn:ietf:wg:oauth:2.0:oob (meaning no redirection).

user_agent

The user agent to use for the requests. Defaults to an instance of LWP::UserAgent. It is expected to have a request method that accepts instances of HTTP::Request objects.

coerce_entities

A boolean value. Set to true if you want Mastodon::Client to internally coerce all response entities to objects. This adds a level of validation, and can make the objects easier to use.

Although this does require some additional processing, the coercion is done by Type::Tiny, so the impact is negligible.

For now, it defaults to false (but this will likely change, so I recommend you use it).

access_token

The access token of your client. This is provided by the Mastodon API and is used for the OAuth2 authentication required for most API calls.

You can get this by calling authorize with either an access code or your account's username and password.

authorized

Boolean. False is the client has no defined access_token. When an access token is set, this is set to true or to a DateTime object representing the time of authorization if possible (as received from the server).

client_id
client_secret

The client ID and secret are provided by the Mastodon API when you register your client using the register method. They are used to identify where your calls are coming from, and are required before you can use the authorize method to get the access token.

name

Your client's name. This is required when registering, but is otherwise seldom used. If you are using the authorization_url to get an access code from your users, then they will see this name when they go to that page.

account

Holds the authenticated account. It is set internally by the get_account method.

scopes

This array reference holds the scopes set by you for the client. These are required when registering your client with the Mastodon instance. Defaults to read.

Mastodon::Client will internally make sure that the scopes you were provided when calling authorize match those that you requested. If this is not the case, it will helpfully die.

website

The URL of a human-readable website for the client. If made available, it appears as a link in the "authorized applications" tab of the user preferences in the default Mastodon web GUI. Defaults to the empty string.

status

The content of the status, as a string. Since this is already provided as the first argument of the method, this is not necessary. But if provided, this value will overwrite that of the first argument.

in_reply_to_id

The optional ID of a status to reply to.

Timelines

timeline($query)
timeline($query, $params)

Retrieves a timeline. The first argument defines either the name of a timeline (which can be one of home or public), or a hashtag (if it begins with the # character). This argument is mandatory.

In addition to the global GET parameters, this method accepts the following parameters:

Accessing the public and tag timelines does not require authentication.

local

Boolean. If true, limits results only to those originating from the current instance. Only applies to public and tag timelines.

Depending on the value of coerce_entities, it returns an array of Mastodon::Entity::Status objects, or a plain array reference. The more recent statuses come first.

STREAMING RESULTS

Alternatively, it is possible to use the streaming API to get a constant stream of updates. To do this, there is the stream() method.

stream($query)

Creates a Mastodon::Listener object which will fetch a stream for the specified query. Possible values for the query are either user, for events that are relevant to the authorized user; public, for all public statuses; or a tag (if it begins with the # character), for all public statuses for the particular tag.

For more details on how to use this object, see the documentation for Mastodon::Listener.

Accessing streaming public timeline will not require authentication (but as of this writing still does).

REQUEST METHODS

Mastodon::Client uses four lower-level request methods to contact the API with GET, POST, PATCH, and DELETE requests. These are left available in case one of the higher-level convenience methods are unsuitable or undesirable, but you use them at your own risk.

They all take a URL as their first parameter, which can be a string with the API endpoint to contact, or a URI object, which will be used as-is.

If passed as a string, the methods expect one that contains only the variable parts of the endpoint (ie. not including the HOST/api/v1 part). The remaining parts will be filled-in appropriately internally.

delete($url)
get($url)
get($url, $params)

Query parameters can be passed as part of the URI object, but it is not recommended you do so, since Mastodon has expectations for array parameters that do not meet those of eg. URI::QueryParam. It will be easier and safer if any additional parameters are passed as a hash reference, which will be added to the URL before the request is sent.

post($url)
post($url, $data)
patch($url)
patch($url, $data)

the post and patch methods work similarly to get and delete, but the optional hash reference is sent in as form data, instead of processed as query parameters. The Mastodon API does not use query parameters on POST or PATCH endpoints.

CONTRIBUTIONS AND BUG REPORTS

Contributions of any kind are most welcome!

The main repository for this distribution is on GitLab, which is where patches and bug reports are mainly tracked. The repository is also mirrored on Github, in case that platform makes it easier to post contributions.

If none of the above is acceptable, bug reports can also be sent through the CPAN RT system, or by mail directly to the developers at the address below, although these will not be as closely tracked.
