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, 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
