""" 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 """ from ranger.api.apps import * from ranger.ext.get_executables import get_executables class CustomApplications(Applications): def app_default(self, c): """How to determine the default application?""" f = c.file if f.basename.lower() == 'makefile': return self.either(c, 'make') if f.extension is not None: if f.extension in ('pdf', ): c.flags += 'd' return self.either(c, 'evince', 'zathura', 'apvlv') if f.extension in ('xml', ): return self.either(c, 'editor') if f.extension in ('html', 'htm', 'xhtml'): return self.either(c, 'firefox', 'opera', 'elinks') if f.extension in ('swf', ): return self.either(c, 'firefox', 'opera') if f.extension == 'nes': return self.either(c, 'fceux') if f.extension in ('swc', 'smc'): return self.either(c, 'zsnes') if f.mimetype is not None: if INTERPRETED_LANGUAGES.match(f.mimetype): return self.either(c, 'edit_or_run') if f.container: return self.either(c, 'aunpack', 'file_roller') if f.video or f.audio: if f.video: c.flags += 'd' return self.either(c, 'mplayer', 'totem') if f.image: return self.either(c, 'feh', 'eog', 'mirage') if f.document or f.filetype.startswith('text'): return self.either(c, 'editor') # ----------------------------------------- application definitions # Note: Trivial applications are defined at the bottom def app_pager(self, c): return tup('less', *c) def app_editor(self, c): try: default_editor = os.environ['EDITOR'] except KeyError: pass else: parts = default_editor.split() exe_name = os.path.basename(parts[0]) if exe_name in get_executables(): return tuple(parts) + tuple(c) return self.either(c, 'vim', 'emacs', 'nano') @depends_on(app_editor, Applications.app_self) def app_edit_or_run(self, c): if c.mode is 1: return self.app_self(c) return self.app_editor(c) @depends_on('mplayer') def app_mplayer(self, c): if c.mode is 1: return tup('mplayer', '-fs', *c) elif c.mode is 2: args = "mplayer -fs -sid 0 -vfm ffmpeg -lavdopts " \ "lowres=1:fast:skiploopfilter=all:threads=8".split() args.extend(c) return tup(*args) elif c.mode is 3: return tup('mplayer', '-mixer', 'software', *c) else: return tup('mplayer', *c) @depends_on('feh') def app_feh(self, c): arg = {1: '--bg-scale', 2: '--bg-tile', 3: '--bg-center'} c.flags += 'd' if c.mode in arg: return tup('feh', arg[c.mode], c.file.path) if c.mode is 4: # Note: mode 4 wouldn't need to depend on 'feh' return self.either(c, 'gimp') if c.mode is 11: if len(c.files) > 1: return tup('feh', *c) else: from collections import deque directory = self.fm.env.get_directory(c.file.dirname) images = [f.path for f in directory.files if f.image] position = images.index(c.file.path) deq = deque(images) deq.rotate(-position) return tup('feh', *deq) return tup('feh', *c) @depends_on('aunpack') def app_aunpack(self, c): if c.mode is 0: c.flags += 'p' return tup('aunpack', '-l', c.file.path) return tup('aunpack', c.file.path) @depends_on('file-roller') def app_file_roller(self, c): c.flags += 'd' return tup('file-roller', c.file.path) @depends_on('make') def app_make(self, c): if c.mode is 0: return tup("make") if c.mode is 1: return tup("make", "install") if c.mode is 2: return tup("make", "clear") @depends_on('java') def app_java(self, c): def strip_extensions(file): if '.' in file.basename: return file.path[:file.path.index('.')] return file.path files_without_extensions = map(strip_extensions, c.files) return tup("java", files_without_extensions) @depends_on('totem') def app_totem(self, c): if c.mode is 0: return tup("totem", *c) if c.mode is 1: return tup("totem", "--fullscreen", *c) # Often a programs invocation is trivial.
