Guard::Addremove

This guard allows you execute shell commands whenever files are added or removed. It is very much like guard-shell, but ignores changes to existing files.

Make sure you have guard installed.

Install the gem with:

gem install guard-addremove

Or add it to your Gemfile:

gem 'guard-addremove'

And then add a basic setup to your Guardfile:

guard init addremove

This guard was originally written to allow the removal of caches when the filesystem changes. This can be helpful in combination with vim's plugins CtrlP or Command-T. Find a quick guide how to use it in my blog.

guard :addremove do
  watch /.*/ do |m|
    `echo "#{m[0]} has been added or removed."`
  end
end

will simply print a message telling you a file has been added or removed.
