System command aliases.

Bases: IPython.config.configurable.Configurable
Call an alias given its name and the rest of the line.
Get the config class config section
Get the help string for this class in ReST format.
If inst is given, it’s current trait values will be used in place of class defaults.
Get the help string for a single trait.
If inst is given, it’s current trait values will be used in place of the class default.
Get the help string for a single trait and print it.
Get a list of all the names of this classes traits.
This method is just like the trait_names() method, but is unbound.
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.
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.
An instance of a Python list.
Define a new alias after validating it.
This will raise an AliasError if there are validation problems.
Expand an alias in the command line
Returns the provided command line, possibly with the first word (command) translated according to alias expansion rules.
Expand multiple levels of aliases:
if:
alias foo bar /tmp alias baz foo
then:
baz huhhahhei -> bar /tmp huhhahhei
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
name : list, str, None
remove : bool

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.
Define an alias, but don’t raise on an AliasError.
Get metadata values for trait by key.
Get a list of all the names of this classes traits.
Get a list of all the traits of this class.
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.
Transform alias to system command string.
Fire the traits events when the config is updated.
An instance of a Python list.
Validate an alias and return the its number of arguments.
