NAME

    Net::Async::Matrix - use Matrix with IO::Async

SYNOPSIS

     use Net::Async::Matrix;
     use IO::Async::Loop;
    
     my $loop = IO::Async::Loop->new;
    
     my $matrix = Net::Async::Matrix->new(
        server => "my.home.server",
     );
    
     $loop->add( $matrix );
    
     $matrix->login(
        user_id  => '@my-user:home.server',
        password => 'SeKr1t',
     )->get;

DESCRIPTION

    Matrix is an new open standard for interoperable Instant Messaging and
    VoIP, providing pragmatic HTTP APIs and open source reference
    implementations for creating and running your own real-time
    communication infrastructure.

    This module allows an program to interact with a Matrix homeserver as a
    connected user client.

EVENTS

    The following events are invoked, either using subclass methods or CODE
    references in parameters:

 on_log $message

    A request to write a debugging log message. This is provided
    temporarily for development and debugging purposes, but will at some
    point be removed when the code has reached a certain level of
    stability.

 on_presence $user, %changes

    Invoked on receipt of a user presence change event from the homeserver.
    %changes will map user state field names to 2-element ARRAY references,
    each containing the old and new values of that field.

 on_room_new $room

    Invoked when a new room first becomes known about.

    Passed an instance of Net::Async::Matrix::Room.

 on_room_del $room

    Invoked when the user has now left a room.

 on_invite $event

    Invoked on receipt of a room invite. The $event will contain the plain
    Matrix event as received; with at least the keys inviter and room_id.

 on_unknown_event $event

    Invoked on receipt of any sort of event from the event stream, that is
    not recognised by any of the other code. This can be used to handle new
    kinds of incoming events.

PARAMETERS

    The following named parameters may be passed to new or configure. In
    addition, CODE references for event handlers using the event names
    listed above can also be given.

 server => STRING

    Hostname and port number to contact the homeserver at. Given in the
    form

     $hostname:$port

    This string will be interpolated directly into HTTP request URLs.

 SSL => BOOL

    Whether to use SSL/TLS to communicate with the homeserver. Defaults
    false.

 SSL_* => ...

    Any other parameters whose names begin SSL_ will be stored for passing
    to the HTTP user agent. See IO::Socket::SSL for more detail.

 path_prefix => STRING

    Optional. Gives the path prefix to find the Matrix client API at.
    Normally this should not need modification.

 on_room_member, on_room_message => CODE

    Optional. Sets default event handlers on new room objects.

 enable_events => BOOL

    Optional. Normally enabled, but if set to a defined-but-false value
    (i.e. 0 or empty string) the event stream will be disabled. This will
    cause none of the incoming event handlers to be invoked, because the
    server will not be polled for events.

    This may be useful in simple send-only cases where the client has no
    interest in receiveing any events, and wishes to reduce the load on the
    homeserver.

 longpoll_timeout => NUM

    Optional. Timeout in seconds for the /events longpoll operation.
    Defaults to 30 seconds if not supplied.

 first_sync_limit => NUM

    Optional. Number of events per room to fetch on the first /sync request
    on startup. Defaults to the server's builtin value if not defined,
    which is likely to be 10.

METHODS

    The following methods documented with a trailing call to ->get return
    Future instances.

 login

       $matrix->login( %params )->get

    Performs the necessary steps required to authenticate with the
    configured Home Server, actually obtain an access token and starting
    the event stream (unless disabled by the enable_events option being
    false). The returned Future will eventually yield the $matrix object
    itself, so it can be easily chained.

    There are various methods of logging in supported by Matrix; the
    following sets of arguments determine which is used:

    user_id, password

      Log in via the m.login.password method.

    user_id, access_token

      Directly sets the user_id and access_token fields, bypassing the
      usual login semantics. This presumes you already have an existing
      access token to re-use, obtained by some other mechanism. This exists
      largely for testing purposes.

 register

       $matrix->register( %params )->get

    Performs the necessary steps required to create a new account on the
    configured Home Server.

 sync

       $matrix->sync( %params )->get

    Performs a single /sync request on the server, returning the raw
    results directly.

    Takes the following named parameters

    since => STRING

      Optional. Sync token from the previous request.

 start

       $f = $matrix->start

    Performs the initial sync on the server, and starts the event stream to
    begin receiving events.

    While this method does return a Future it is not required that the
    caller keep track of this; the object itself will store it. It will
    complete when the initial sync has fininshed, and the event stream has
    started.

    If the initial sync has already been requested, this method simply
    returns the future it returned the last time, ensuring that you can
    await the client starting up simply by calling it; it will not start a
    second time.

 stop

       $matrix->stop

    Stops the event stream. After calling this you will need to use start
    again to continue receiving events.

 myself

       $user = $matrix->myself

    Returns the user object representing the connected user.

 user

       $user = $matrix->user( $user_id )

    Returns the user object representing a user of the given ID, if
    defined, or undef.

 get_displayname

 set_displayname

       $name = $matrix->get_displayname->get
    
       $matrix->set_displayname( $name )->get

    Accessor and mutator for the user account's "display name" profile
    field.

 get_presence

 set_presence

       ( $presence, $msg ) = $matrix->get_presence->get
    
       $matrix->set_presence( $presence, $msg )->get

    Accessor and mutator for the user's current presence state and optional
    status message string.

 create_room

       ( $room, $room_alias ) = $matrix->create_room( $alias_localpart )->get

    Requests the creation of a new room and associates a new alias with the
    given localpart on the server. The returned Future will return an
    instance of Net::Async::Matrix::Room and a string containing the full
    alias that was created.

 join_room

       $room = $matrix->join_room( $room_alias_or_id )->get

    Requests to join an existing room with the given alias name or plain
    room ID. If this room is already known by the $matrix object, this
    method simply returns it.

 add_alias

 delete_alias

       $matrix->add_alias( $alias, $room_id )->get
    
       $matrix->delete_alias( $alias )->get

    Performs a directory server request to create the given room alias
    name, to point at the room ID, or to remove it again.

    Note that this is likely only to be supported for alias names scoped
    within the homeserver the client is connected to, and that additionally
    some form of permissions system may be in effect on the server to limit
    access to the directory server.

 upload

       $content_uri = $matrix->upload( %params )->get

    Performs a post to the server's media content repository, to upload a
    new piece of content, returning the content URI that points to it.

    The content can be specified in any of three ways, with the following
    three mutually-exclusive arguments:

    content => STRING

      Gives the content directly as an immediate scalar value.

    file => STRING

      Gives the path to a readable file on the filesystem containing the
      content.

    fh => IO

      Gives an opened IO handle the content can be read from.

    The following additional arguments are also recognised:

    content_type => STRING

      Gives the MIME type of the content data.

    content_length => INT

      Optional. If the content is being delivered from an opened filehandle
      (via the fh argument), this gives the total length in bytes. This is
      required in cases such as reading from pipes, when the length of the
      content isn't immediately available such as by stat()ing the
      filehandle.

 convert_mxc_url

       $url = $matrix->convert_mxc_url( $mxc )

    Given a plain string or URI instance containing a Matrix media URL (in
    the mxc: scheme), returns an http: or https: URL in the form of an URI
    instance pointing at the media repository on the user's local
    homeserver where it can be downloaded from.

USER STRUCTURES

    Parameters documented as $user receive a user struct, which supports
    the following methods:

 $user_id = $user->user_id

    User ID of the user.

 $displayname = $user->displayname

    Profile displayname of the user.

 $presence = $user->presence

    Presence state. One of offline, unavailable or online.

 $last_active = $user->last_active

    Epoch time that the user was last active.

SUBCLASSING METHODS

    The following methods are not normally required by users of this class,
    but are provided for the convenience of subclasses to override.

 $room = $matrix->make_room( %params )

    Returns a new instance of Net::Async::Matrix::Room.
