A file watcher for Elixir.

Installation

The package can be installed as:

1. Add fwatch to your list of dependencies in mix.exs:

   def deps do
     [{:fwatch, "~> 0.1.0"}]
   end
   

2. Ensure fwatch is started before your application:

   def application do
     [applications: [:fwatch]]
   end
   

Usage

Examples

# Watch a file and registers a callback
Fwatch.watch_file("filename", fn path, events ->
  if :modified in events do
    IO.puts("#{path} is modified")
  end
end)
# Watch multiple files and registers a callback
Fwatch.watch_file(["filename1", "filename2"], callback)
# Watch a directory and registers a callback
Fwatch.watch_dir("dirname", callback)
# Watch multiple directories and registers a callback
Fwatch.watch_dir(["dirname1", "dirname2"], callback)

See Lists Events from Backend for details of events.

You can also use regular expressions as a filename or dirname like this:
Fwatch.watch_file(~r"/User/tmp/.*", callback)
