In fact, you can just copy this +# file there with `ranger --copy-config=commands' and make your modifications. +# But make sure you update your configs when you update ranger. +# +# =================================================================== +# Every class defined here which is a subclass of `Command' will be used as a +# command in ranger. Several methods are defined to interface with ranger: +# execute(): called when the command is executed. +# cancel(): called when closing the console. +# tab(): called when is pressed. +# quick(): called after each keypress. +# +# The return values for tab() can be either: +# None: There is no tab completion +# A string: Change the console to this string +# A list/tuple/generator: cycle through every item in it +# +# The return value for quick() can be: +# False: Nothing happens +# True: Execute the command afterwards +# +# The return value for execute() and cancel() doesn't matter. +# +# =================================================================== +# Commands have certain attributes and methods that facilitate parsing of +# the arguments: +# +# self.line: The whole line that was written in the console. +# self.args: A list of all (space-separated) arguments to the command. +# self.quantifier: If this command was mapped to the key "X" and +# the user pressed 6X, self.quantifier will be 6. +# self.arg(n): The n-th argument, or an empty string if it doesn't exist. +# self.rest(n): The n-th argument plus everything that followed. For example, +# If the command was "search foo bar a b c", rest(2) will be "bar a b c" +# self.start(n): The n-th argument and anything before it. For example, +# If the command was "search foo bar a b c", rest(2) will be "bar a b c" +# +# =================================================================== +# And this is a little reference for common ranger functions and objects: +# +# self.fm: A reference to the "fm" object which contains most information +# about ranger. +# self.fm.notify(string): Print the given string on the screen. +# self.fm.notify(string, bad=True): Print the given string in RED. +# self.fm.reload_cwd(): Reload the current working directory. +# self.fm.thisdir: The current working directory.
