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

You can place this file in your ~/.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 ~/.ranger/apps.py example
	from ranger.defaults.apps import CustomApplications as DefaultApps
	from ranger.api.apps import *
			
	class CustomApplications(DefaultApps):
		def app_kaffeine(self, c):
			return tup('kaffeine', *c)

		def app_feh_fullscreen_by_default(self, c):
			return tup('feh', '-F', *c)

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

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

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