rb-fsevent

Very simple & usable Mac OSX FSEvents API

• RubyCocoa not required!

• Signals are working (really) – I don’t know if they are or not.

• Tested on MRI 1.8.7 & 1.9.2, JRuby 1.6.3

• Tested on 10.5.8

• Works on PowerPC

Install

gem install rb-fsevent-legacy

Usage

Singular path

require 'rb-fsevent-legacy'

fsevent = FSEvent.new(Dir.pwd)

#some changes happen here, other program code, etcj

fsevent.events do |e|
  puts "Detected change inside: #{e.event_path}"
end

Multiple paths

require 'rb-fsevent'

paths = ['/tmp/path/one', '/tmp/path/two', Dir.pwd]

fsevent = FSEvent.new
fsevent.add_paths(paths)
fsevent.watch do |e|
  puts "Detected change inside: #{e.event_path}"
end

#some things happen

fsevent.events.collect { |e| e.event_path }

Threads

The native stream runs in it's own (isolated) CoreFoundation thread, which is started as soon as the gem
is loaded and it terminated when the program stops.  You may check for changes as often as you like in 
ruby loop, or from an additional Ruby thread.
