Send notifications to [Slack](https://slack.com) about [Capistrano](http://www.capistranorb.com) deployments.

If you need Capistrano v2 support, check out [capistrano-slack](https://github.com/j-mcnally/capistrano-slack).

## Requirements

- Capistrano >= 3
- Ruby >= 2.0
- A Slack account

## Installation

Add this line to your application's Gemfile:

    gem 'slackistrano', require: false

And then execute:

    $ bundle

## Configuration

Set up an "Incoming WebHooks" integration in Slack.  Make a note 
of the token as you'll need it later.

Require the library in your application's Capfile:

    require 'slackistrano'

Set your team and token in your application's config/deploy.rb:

    set :slack_team, "supremegolf"
    set :slack_token, "xxxxxxxxxxxxxxxxxxxxxxxx"

Optionally, override the other slack settings:

    set :slack_icon_url,     ->{ 'http://gravatar.com/avatar/885e1c523b7975c4003de162d8ee8fee?r=g&s=40' }
    set :slack_icon_emoji,   ->{ nil } # will override icon_url
    set :slack_channel,      ->{ '#general' }
    set :slack_username,     ->{ 'Slackistrano' }
    set :slack_run_starting, ->{ true }
    set :slack_run_finished, ->{ true }
    set :slack_run_failed,   ->{ true }
    set :slack_msg_starting, ->{ "#{ENV['USER'] || ENV['USERNAME']} has started deploying branch #{fetch :branch} of #{fetch :application} to #{fetch :rails_env, 'production'}." }
    set :slack_msg_finished, ->{ "#{ENV['USER'] || ENV['USERNAME']} has finished deploying branch #{fetch :branch} of #{fetch :application} to #{fetch :rails_env, 'production'}." }
    set :slack_msg_failed,   ->{ "*ERROR!* #{ENV['USER'] || ENV['USERNAME']} failed to deploy branch #{fetch :branch} of #{fetch :application} to #{fetch :rails_env, 'production'}." }

**Note**: You may wish to disable one of the notifications if another service (ex:
Honeybadger) also displays a deploy notification.

Test your setup by running:

    $ cap production slack:deploy:starting
    $ cap production slack:deploy:finished
    $ cap production slack:deploy:failed

## Usage

Deploy your application like normal and you should see messages in the channel
you specified.

## TODO

- Notify about incorrect configuration settings.
- Notify about unsuccessfull HTTP POSTs.
