# =================================================================== # This is the configuration file for file type detection and application # handling. It's all in python; lines beginning with # are comments. # # Scroll down for a few examples. # =================================================================== # This system is based on things called MODES and FLAGS. You can read # in the man page about them. To remind you, here's a list of all flags. # An uppercase flag inverts previous flags of the same name. # s Silent mode. Output will be discarded. # d Detach the process. (Run in background) # p Redirect output to the pager # w Wait for an Enter-press when the process is done # c Run the current file only, instead of the selection # # To implement flags in this file, you could do this: # context.flags += "d" # Another example: # context.flags += "Dw" # # To implement modes in this file, you can do something like: # if context.mode == 1: # <run in one way> # elif context.mode == 2: # <run in another way> # =================================================================== # The methods are called with a "context" object which provides some # attributes that transfer information. Relevant attributes are: # # mode -- a number, mainly used in determining the action in app_xyz() # flags -- a string with flags which change the way programs are run # files -- a list containing files, mainly used in app_xyz # filepaths -- a list of the paths of each file # file -- an arbitrary file from that list (or None) # fm -- the filemanager instance # popen_kws -- keyword arguments which are directly passed to Popen # =================================================================== # The return value of the functions should be either: # 1. A reference to another app, like: # return self.app_editor(context) # # 2. A call to the "either" method, which uses the first program that # is installed on your system. If none are installed, None is returned. # return self.either(context, "libreoffice", "soffice", "ooffice") # # 3. A tuple of arguments that should be run. # return "mplayer", "-fs", context.file.path # If you use lists instead of strings, they will be flattened: # args = ["-fs", "-shuf"] # return "mplayer", args, context.filepaths # "context.filepaths" can, and will often be abbreviated with just "context": # return "mplayer", context # # 4. "None" to indicate that no action was found. # return None # =================================================================== # When using the "either" method, ranger determines which program to # pick by looking at its dependencies. You can set dependencies by # adding the decorator "depends_on": # @depends_on("vim") # def app_vim(self, context): # .... # There is a special keyword which you can use as a dependence: "X" # This ensures that the program will only run when X is running. # =================================================================== # Import the basics from ranger.defaults.apps import CustomApplications as DefaultApps from ranger.api.apps import * # # Here, the class "CustomApplications" is defined as a subclass of the default # application handler class. It is located at ranger/defaults/apps.py and # contains a whole lot of definitions. The reason why we don't put them here # is that when you update, this file doesn't change. class CustomApplications(DefaultApps): # By default, this just inherits all methods from DefaultApps pass # def app_kaffeine(self, context): # return 'kaffeine', context # # def app_feh_fullscreen_by_default(self, context): # return 'feh', '-F', context # # # app_default is the function that is always called to determine which # # application to run, unless you specify one manually with :open_with # 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) # # # You could write this to use an entirely different program to open files: # def app_default(self, context): # return "mimeopen", context ## Often a programs invocation is trivial. For example: ## vim test.py readme.txt [...] ## ## This could be implemented like: ## @depends_on("vim") ## def app_vim(self, context): ## return "vim", context ## ## But this is redundant and ranger does this automatically. However, sometimes ## you want to change some properties like flags or dependencies. This can be ## done with the generic() classmethod. #CustomApplications.generic('zsnes', 'wine', deps=['X']) ## By setting flags='d', this programs will not block ranger's terminal: #CustomApplications.generic('gimp', 'evince', deps=['X'], flags='d')
