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
