This is the default ranger configuration file for filetype detection
and application handling.

You can place this file in your ~/.config/ranger/ directory and it will be used
instead of this one.  Though, to minimize your effort when upgrading ranger,
you may want to subclass CustomApplications rather than making a full copy.
            
This example modifies the behaviour of "feh" and adds a custom media player:

#### start of the ~/.config/ranger/apps.py example
	from ranger.defaults.apps import CustomApplications as DefaultApps
	from ranger.api.apps import *
			
	class CustomApplications(DefaultApps):
		def app_kaffeine(self, context):
			return 'kaffeine', context

		def app_feh_fullscreen_by_default(self, context):
			return 'feh', '-F', context

		def app_default(self, context):
			f = context.file #shortcut
			if f.video or f.audio:
				return self.app_kaffeine(context)

			if f.image and context.mode == 0:
				return self.app_feh_fullscreen_by_default(context)

			return DefaultApps.app_default(self, context)
#### end of the example
