资源说明：A simple directory watcher
# Watch, dirt simple mechanism to tell if files have changed
Pass Watch a Dir.glob friendly path and a block that you'd like to
be executed when something changes
Watch.new("**/*") { puts "file added, removed or changed" }
## Why write another directory watcher?
Simplicity.
If you've checked already, there are many implementations of the same kind of code.
[kicker](http://github.com/alloy/kicker/), [watchr](http://github.com/mynyml/watchr/) and [directory_watcher](http://github.com/TwP/directory_watcher/) are all pretty awesome, only the code bases are lengthy.
| Library | SLOC |
|:-----------------:|:--------:|
|kicker | 676 |
|directory_watcher | 478 |
|watchr | 268 |
|watch | 27 |
All three of these libraries of course had far different goals than I did for watch. They're all well tested and pretty awesome too. Use them if watch isn't enough for you.
## Note on Patches/Pull Requests
* Fork the project.
* Make your feature addition or bug fix.
* Add tests for it. This is important so I don't break it in a
future version unintentionally.
* Commit, do not mess with rakefile, version, or history.
(if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
* Send me a pull request. Bonus points for topic branches.
