The message to show when the limit of inotify watchers is not enough
Initializes the Adapter. See {Listen::Adapter#initialize} for more info.
# File lib/listen/adapters/linux.rb, line 26 def initialize(directories, options = {}, &callback) super @worker = init_worker rescue Errno::ENOSPC abort(INOTIFY_LIMIT_MESSAGE) end
Check if the adapter is usable on the current OS.
@return [Boolean] whether usable or not
# File lib/listen/adapters/linux.rb, line 65 def self.usable? return false unless RbConfig::CONFIG['target_os'] =~ /linux/ require 'rb-inotify' true rescue LoadError false end
Starts the adapter.
@param [Boolean] blocking whether or not to block the current thread after starting
# File lib/listen/adapters/linux.rb, line 37 def start(blocking = true) @mutex.synchronize do return if @stop == false super end @worker_thread = Thread.new { @worker.run } @poll_thread = Thread.new { poll_changed_dirs } @poll_thread.join if blocking end
Stops the adapter.
# File lib/listen/adapters/linux.rb, line 50 def stop @mutex.synchronize do return if @stop == true super end @worker.stop Thread.kill(@worker_thread) if @worker_thread @poll_thread.join end
Initializes a INotify worker and adds a watcher for each directory passed to the adapter.
@return [INotify::Notifier] initialized worker
