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
