DESCRIPTION

This allows a Bot::Backbone chat bot to be connect to a Slack server using their Real-Time Messaging API.

This is based on AnyEvent::SlackRTM and WebService::Slack::WebApi. It also uses a CHI cache to help avoid contacting the Slack server too often, which could result in your bot becoming rate limited.

ATTRIBUTES

token

The token is the access token from Slack to use. This may be either of the following type of tokens:

  • User Token. This is a token to perform actions on behalf of a user account.

  • Bot Token. If you configure a bot integration, you may use the access token on the bot configuration page to use this library to act on behalf of the bot account. Bot accounts may not have the same features as a user account, so please be sure to read the Slack documentation to understand any differences or limitations.

Which you use will depend on whether you want the bot to control a user account or a bot integration account. You are responsible for adhering to the Slack terms of use in whatever you do.

cache

This is a CHI cache to use to temporarily store response from the Slack APIs. By default, this is a memory-only cache that caches data for only 60 seconds. The purpose is mainly to prevent repeated requests to the API, which might result in rate limiting.

api

This is the WebService::Slack::WebApi object used to contact Slack for information about channels, users, etc.

rtm

This is the AnyEvent::SlackRTM object used to communicate with Slack and trigger events from the Real-Time Messaging API.

error_callback

This is a callback sub that may be used to report error events from the RTM API. Set it to a sub that will be called as follows:

sub {
    my ($self, $rtm, $message) = @_;

    ...
}

Here, $self is the Bot::Backbone::Service::SlackChat object, $rtm is the AnyEvent::SlackRTM object, and $message is a hash containing the error message, as described on the Real Time Messaging API documentation.

whoami

This returns a hash containing information about who the bot is.

METHODS

user

Returns the name of the bot.

user_id

Returns the user ID for the bot.

team_id

Returns the team ID for the team account.

initialize

This connects to Slack and prepares the bot for communication.

load_user

method load_user($by, $value) returns Bot::Backbone::Identity

Fetches information about a user from Slack and returns the user as a Bot::Backbone::Identity. The $by setting determines how the user is looked up, which may either be by "id" or by "name". The value, then, is the value to check.

load_me

method load_me() returns Bot::Backbone::Identity

Returns the identity object for the bot itself.

load_user_channel

method load_user_channel($by, $value) returns Str

Returns the ID of a user's IM channel. Here $by may be "user" to lookup by user ID.

join_group

method join_group({ group => $group })

Given the ID of a channel or group, this causes the bot to open or join it. Note that Slack bot integration accounts might not be able to join team channels, but may still be invited.

got_message

Handles messages from Slack. Decides whether they are group messages or direct and forwards them on as appropriate. Messages with a "subtype" will be ignored as will messages that are "edited".

This method also marks messages as read.

got_direct_message

Handles direct messages received from an IM channel.

is_to_me

This determines whether or not the message is to the bot.

got_group_message

This handles message received from private group or team channels.

send_message

method send_message({
    to          => $user_id,
    group       => $group_id,
    text        => $message,
    attachments => $attachments,
})

This sends a message to a Slack channel. To the named user's IM channel or to a private group or team channel named by $group_id. Attachments can be included to produce formatted messages.
