Classes

ProfileApp

class IPython.core.profileapp.ProfileApp(**kwargs)

Bases: IPython.config.application.Application

__init__(**kwargs)

aliases

An instance of a Python dict.

classmethod class_config_section()

Get the config class config section

classmethod class_get_help()

Get the help string for this class in ReST format.

classmethod class_get_trait_help(trait)

Get the help string for a single trait.

classmethod class_print_help()

Get the help string for a single trait and print it.

classmethod class_trait_names(**metadata)

Get a list of all the names of this classes traits.

This method is just like the trait_names() method, but is unbound.

classmethod class_traits(**metadata)

Get a list of all the traits of this class.

This method is just like the traits() method, but is unbound.

The TraitTypes returned don’t know anything about the values that the various HasTrait’s instances are holding.

This follows the same algorithm as traits does and does not allow for any simple way of specifying merely that a metadata name exists, but has any value. This is because get_metadata returns None if a metadata key doesn’t exist.

classes

An instance of a Python list.

classmethod clear_instance()

unset _instance for this class and singleton parents.

config

A trait whose value must be an instance of a specified class.

The value can also be an instance of a subclass of the specified class.

created = None

description = "Manage IPython profiles\n\nProfile directories contain\nconfiguration, log and security related files and are named\nusing the convention 'profile_<name>'. By default they are\nlocated in your ipython directory. You can create profiles\nwith `ipython profile create <name>`, or see the profiles you\nalready have with `ipython profile list`\n\nTo get started configuring IPython, simply do:\n\n$> ipython profile create\n\nand IPython will create the default profile in <ipython_dir>/profile_default,\nwhere you can edit ipython_config.py to start configuring IPython.\n\n"

examples = '\nipython profile create -h # show the help string for the create subcommand\nipython profile list -h # show the help string for the list subcommand\n'

exit(exit_status=0)

extra_args

An instance of a Python list.

flags

An instance of a Python dict.

generate_config_file()

generate default config file from Configurables

init_logging()

Start logging for this application.

The default is to log to stdout using a StreaHandler. The log level starts at loggin.WARN, but this can be adjusted by setting the log_level attribute.

initialize(argv=None)

Do the basic steps to configure me.

Override in subclasses.

initialize_subcommand(subc, argv=None)

Initialize a subcommand with argv.

classmethod initialized()

classmethod instance(*args, **kwargs)

Returns a global instance of this class.

This method create a new instance if none have previously been created and returns a previously created instance is one already exists.

The arguments and keyword arguments passed to this method are passed on to the __init__() method of the class upon instantiation.

Examples

Create a singleton class using instance, and retrieve it:

>>> from IPython.config.configurable import SingletonConfigurable
>>> class Foo(SingletonConfigurable): pass
>>> foo = Foo.instance()
>>> foo == Foo.instance()
True

Create a subclass that is retrived using the base class instance:

>>> class Bam(Bar): pass
>>> bam = Bam.instance()
>>> bam == Bar.instance()
True

keyvalue_description

name = u'ipython-profile'

on_trait_change(handler, name=None, remove=False)

Setup a handler to be called when a trait changes.

This is used to setup dynamic notifications of trait changes.

Static handlers can be created by creating methods on a HasTraits subclass with the naming convention ‘_[traitname]_changed’. Thus, to create static handler for the trait ‘a’, create the method _a_changed(self, name, old, new) (fewer arguments can be used, see below).

Parameters :

handler : callable

A callable that is called when a trait changes. Its signature can be handler(), handler(name), handler(name, new) or handler(name, old, new).

name : list, str, None

If None, the handler will apply to all traits. If a list of str, handler will apply to all names in the list. If a str, the handler will apply just to that name.

remove : bool

If False (the default), then install the handler. If True then unintall it.

print_examples()

Print usage and examples.

This usage string goes at the end of the command line help string and should contain examples of the application’s usage.

print_flag_help()
