如何使用 Ruby 在 Windows 上显示简单的通知？

Question

How can I show notifications on Windows from a Ruby script?

Currently, I'm using GMail messages but there's a delay...
I'm trying to receive an alert and seconds/nanoseconds matter.

Thank you

The simplest way to show a notification on Windows with Ruby is to use Win32API and just call MessageBox :

require 'win32api'

MessageBox = Win32API.new('user32', 'MessageBox', ['L', 'P', 'P', 'L'], 'I')
MessageBox.call(0, "Something important happened", "Alert", 0)

Another more advanced setup is to use something like the Growl notifier , and couple it with the ruby_gntp gem, or Notifu + rb_notifu . See here for more info on these types of notification systems:
