osx_watchfolder

osx_watchfolder is a tiny gem to take advantages of OSX 10.5’s folder watching functionality.

osx_watchfolder enables you to point a script at a directory, or group of directories, and be notified of changes. Example usages are autotest-like scripts.

Due to limitations with Ruby threading and Ruby-Cocoa, folders may only be watched from the main Ruby thread.

Only works on OSX 10.5+ (Leopard), obviously.

To run a method ‘run_tests’ when a change is detected in a couple of folders:

require 'rubygems'
require 'osx_watchfolder'
OsxWatchfolder::FolderWatcher.new("lib", "test") { run_tests}.start

• Only works on OSX 10.5+ (Leopard)

sudo gem install osx_watchfolder

or

gem install osx_watchfolder
