Send system notifications on several platforms with a simple and unified API. Currently supports:

• terminal-notifier (Notification Center wrapper for Mac OS X)
• HUD
• Kdialog (Linux/KDE)
• Knotify (Linux/KDE)
• OSD Cat (Linux)
• Libnotify (Linux)
• Snarl (Windows)

gem install notifier

• Install terminal-notifier - https://github.com/alloy/terminal-notifier

terminal-notifier also supports two additional flags:

• subtitle
• sound

See terminal-notifier's help for additional information.

• Install HUD - https://fnando.gumroad.com/l/hud-macos

If you're a linux guy, you can choose one of these methods:

• Install libnotify-bin and its dependencies: sudo aptitude install libnotify-bin
• Install xosd-bin: sudo aptitude install xosd-bin
• KDE users don't need to install anything: Test Notifier will use +knotify+ or +kdialog+.

• Install Snarl: download from http://www.fullphat.net
• Install ruby-snarl: gem install ruby-snarl

Notifier will try to detect which notifiers are available in your system. So you can just send a message:

Notifier.notify(
  image: "image.png",
  title: "Testing Notifier",
  message: "Sending an important message!"
)

Not all notifiers support the image option, therefore it will be ignored.

If your system support more than one notifier, you can specify which one you prefer:

Notifier.default_notifier = :notify_send

Alternatively, you can set the default notifier by using the NOTIFIER env var. The following example assumes test_notifier is configured on this Rails project. The env var has precedence of Notifier.default_notifier.

$ NOTIFIER=hud rails test

The available names are terminal_notifier, kdialog, knotify, notify_send, osd_cat, and snarl.

There are several helper methods that you can use in order to retrieve notifiers.

• Notifier.notifier: return the first supported notifier
• Notifier.notifiers: return all notifiers
• Notifier.supported_notifiers: return only supported notifiers
• Notifier.from_name(name): find notifier by its name
• Notifier.supported_notifier_from_name(name): find a supported notifier by its name

To create a new notifier, just create a module on Notifier namespace that implements the following interface:

module Notifier
  module MyCustomNotifier
    def self.supported?
    end

    def self.notify(options)
    end
  end
end
