Warning
This documentation covers a development version of IPython. The development version may differ significantly from the latest stable release.
Important
This documentation covers IPython versions 6.0 and higher. Beginning with version 6.0, IPython stopped supporting compatibility with Python versions lower than 3.3 including all versions of Python 2.7.
If you are looking for an IPython version compatible with Python 2.7, please use the IPython 5.x LTS release and refer to its documentation (LTS is the long term support release).
Module: core.application
¶
An application for IPython.
All top-level applications should use the classes in this module for handling configuration and creating configurables.
The job of an Application
is to create the master configuration
object and then create the configurable objects, passing the config to them.
2 Classes¶
-
class
IPython.core.application.
ProfileAwareConfigLoader
(filename, path=None, **kw)¶ Bases:
traitlets.config.loader.PyFileConfigLoader
A Python file config loader that is aware of IPython profiles.
-
load_subconfig
(fname, path=None, profile=None)¶ Injected into config file namespace as load_subconfig
-
-
class
IPython.core.application.
BaseIPythonApplication
(**kwargs)¶ Bases:
traitlets.config.application.Application
-
__init__
(**kwargs)¶ Create a configurable given a config config.
Parameters: - config (Config) – If this is empty, default values are used. If config is a
Config
instance, it will be used to configure the instance. - parent (Configurable instance, optional) – The parent Configurable instance of this object.
Notes
Subclasses of Configurable must call the
__init__()
method ofConfigurable
before doing anything else and usingsuper()
:class MyConfigurable(Configurable): def __init__(self, config=None): super(MyConfigurable, self).__init__(config=config) # Then any other code you need to finish initialization.
This ensures that instances will be configured properly.
- config (Config) – If this is empty, default values are used. If config is a
-
excepthook
(etype, evalue, tb)¶ this is sys.excepthook after init_crashhandler
set self.verbose_crash=True to use our full crashhandler, instead of a regular traceback with a short message (crash_handler_lite)
-
init_config_files
()¶ [optionally] copy default config files into profile dir.
-
init_crash_handler
()¶ Create a crash handler, typically setting sys.excepthook to it.
-
init_profile_dir
()¶ initialize the profile dir
-
initialize
(argv=None)¶ Do the basic steps to configure me.
Override in subclasses.
-
initialize_subcommand
(subc, argv=None)¶ Initialize a subcommand with argv.
-
load_config_file
(suppress_errors=None)¶ Load the config file.
By default, errors in loading config are handled, and a warning printed on screen. For testing, the suppress_errors option is set to False, so errors will make tests fail.
supress_errors
default value is to beNone
in which case the behavior default to the one oftraitlets.Application
.- The default value can be set :
- to
False
by setting ‘IPYTHON_SUPPRESS_CONFIG_ERRORS’ environment variable to ‘0’, or ‘false’ (case insensitive). - to
True
by setting ‘IPYTHON_SUPPRESS_CONFIG_ERRORS’ environment variable to ‘1’ or ‘true’ (case insensitive). - to
None
by setting ‘IPYTHON_SUPPRESS_CONFIG_ERRORS’ environment variable to ‘’ (empty string) or leaving it unset.
- to
Any other value are invalid, and will make IPython exit with a non-zero return code.
-
python_config_loader_class
¶ alias of
ProfileAwareConfigLoader
-
stage_default_config_file
()¶ auto generate default config file, and stage it into the profile.
-
