+# -*- coding: utf-8 -*-
+# This file is part of ranger, the console file manager.
+# This configuration file is licensed under the same terms as ranger.
+# ===================================================================
+#
+# NOTE: If you copied this file to ~/.config/ranger/commands_full.py,
+# then it will NOT be loaded by ranger, and only serve as a reference.
+#
+# ===================================================================
+# This file contains ranger's commands.
+# It's all in python; lines beginning with # are comments.
+#
+# Note that additional commands are automatically generated from the methods
+# of the class ranger.core.actions.Actions.
+#
+# You can customize commands in the file ~/.config/ranger/commands.py.
+# It has the same syntax as this file.  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 <TAB> 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): Anything before the n-th argument.  For example, if the
+#      command was "search foo bar a b c", start(2) will be "search foo"
+#
+# ===================================================================
+# 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. (A File object.)
+# self.fm.thisfile: The current file. (A File object too.)
+# self.fm.thistab.get_selection(): A list of all selected files.
+# self.fm.execute_console(string): Execute the string as a ranger command.
+# self.fm.open_console(string): Open the console with the given string
+#      already typed in for you.
+# self.fm.move(direction): Moves the cursor in the given direction, which
+#      can be something like down=3, up=5, right=1, left=1, to=6, ...
+#
+# File objects (for example self.fm.thisfile) have these useful attributes and
+# methods:
+#
+# cf.path: The path to the file.
+# cf.basename: The base name only.
+# cf.load_content(): Force a loading of the directories content (which
+#      obviously works with directories only)
+# cf.is_directory: True/False depending on whether it's a directory.
+#
+# For advanced commands it is unavoidable to dive a bit into the source code
+# of ranger.
+# ===================================================================
