Getting error on file deletion about filewatcher

[thomasfl]

The most natural thing seems to exit with a warning if a file is deleted. New gem has been pushed.

Thanks for the fix - appreciated.

Rather than exiting, what about having a deleted event. Listen does something like this:
https://github.com/guard/listen

Could you please suggest how to command line interface should behave when a file is deleted?

The listen gem have a nice API. One idea is to simply rewrite the CLI to use the listen gem. The command line interface for filewatcher was made to be somewhat simpler than https://github.com/guard/guard.

I prefer filewatcher because its simple and works with files as well as directories. Personally I wouldn't change the API. I'd have it run for any type of file event, e.g.

FileWatcher.new(["lib/"],"Watching files:").watch do |filename|
  puts "File event detected" + filename
  # this could be an change or delete
end

Alternatively for those that wanted to know the type of change event:

FileWatcher.new(["lib/"],"Watching files:").watch do |filename, type|
  puts "File event detected" + filename
  # where type = changed, deleted, etc.
end

Just a suggestion :) Thanks for the lib

I've pushed out a new version that detect deleted files just like you suggested. Please tell me what you think.

FileWatcher.new(["lib/"],"Watching files:").watch do |filename|
  puts "File event detected" + filename
  # this could be an change or delete
end

It is also possible to detect events:

FileWatcher.new(["lib/"],"Watching files:").watch do |filename, type|
  puts "File event detected" + filename
  # where type = :changed or :deleted
end

When a file is deleted, it won't be checked again by filewatcher.
