4 Classes

class IPython.core.alias.AliasError

Bases: Exception

class IPython.core.alias.InvalidAliasError

Bases: AliasError

class IPython.core.alias.Alias(shell, name, cmd)

Bases: object

Callable object storing the details of one alias.

Instances are registered as magic functions to allow use of aliases.

__init__(shell, name, cmd)
validate()

Validate the alias, and return the number of arguments.

class IPython.core.alias.AliasManager(**kwargs: Any)

Bases: Configurable

__init__(shell=None, **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 of Configurable before doing anything else and using super():

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.

define_alias(name, cmd)

Define a new alias after validating it.

This will raise an AliasError if there are validation problems.

get_alias(name)

Return an alias, or None if no alias by that name exists.

is_alias(name)

Return whether or not a given name has been defined as an alias

retrieve_alias(name)

Retrieve the command to which an alias expands.

soft_define_alias(name, cmd)

Define an alias, but don’t raise on an AliasError.

1 Function

IPython.core.alias.default_aliases() → List[Tuple[str, str]]
