# This formatter should usually be used as the base class of all formatters. It

# users to determine how their objects are formatted. The following logic is
# used to find a function to format an given object.
#
# 1. The object is introspected to see if it has a method with the name
#    :attr:`print_method`. If is does, that object is passed to that method
#    for formatting.
# 2. If no print method is found, three internal dictionaries are consulted
#    to find print method: :attr:`singleton_printers`, :attr:`type_printers`
#    and :attr:`deferred_printers`.
#
# Users should use these dictionaries to register functions that will be used to
# compute the format data for their objects (if those objects don't have the
# special print methods). The easiest way of using these dictionaries is through
# the :meth:`for_type` and :meth:`for_type_by_name` methods.

# If no function/callable is found to compute the format data, ``None`` is
# returned and this format type is not used.

# Base class for implementing magic functions.

# Shell functions which can be reached as %function_name. All magic functions
# should accept a string, which they can parse for their own needs. This can
# make some functions easier to type, eg `%cd ../` vs. `%cd("../")`
#
# Classes providing magic functions need to subclass this class, and they MUST:
#
# - Use the method decorators `@line_magic` and `@cell_magic` to decorate
#   individual methods as magic functions, AND
#
# - Use the class decorator `@magics_class` to ensure that the magic
