+<span class="sd">&quot;&quot;&quot; Provider of a framework that dynamically determines the contents of a</span>
+<span class="sd">    context at the time of interaction with the contents rather than at the</span>
+<span class="sd">    time a class is written.</span>
+
+<span class="sd">    This capability is particularly useful when the object acting as a context</span>
+<span class="sd">    is part of a plug-in application -- such as Envisage.  In general, this</span>
+<span class="sd">    capability allows the context to be:</span>
+
+<span class="sd">    - Extendable by contributions from somewhere other than the original</span>
+<span class="sd">      code writer</span>
+<span class="sd">    - Dynamic in that the elements it is composed of can change each time</span>
+<span class="sd">      someone interacts with the contents of the context.</span>
+
+<span class="sd">    It should be noted that this capability is explicitly different from</span>
+<span class="sd">    contexts that look at another container to determine their contents, such</span>
+<span class="sd">    as a file system context!</span>
+
+<span class="sd">    Users of this framework contribute items to a dynamic context by adding</span>
+<span class="sd">    traits to the dynamic context instance.  (This addition can happen</span>
+<span class="sd">    statically through the use of a Traits Category.)  The trait value is the</span>
+<span class="sd">    context item&#39;s value and the trait definition&#39;s metadata determines how the</span>
+<span class="sd">    item is treated within the context.  The support metadata is:</span>
+
+<span class="sd">    context_name: A non-empty string</span>
+<span class="sd">        Represents the name of the item within this context.  This must be</span>
+<span class="sd">        present for the trait to show up as a context item though the value</span>
+<span class="sd">        may change over time as the item gets bound to different names.</span>
+<span class="sd">    context_order: A float value</span>
+<span class="sd">        Indicates the position for the item within this context.  All</span>
+<span class="sd">        dynamically contributed context items are sorted by ascending order</span>
+<span class="sd">        of this value using the standard list sort function.</span>
+<span class="sd">    is_context: A boolean value</span>
+<span class="sd">        True if the item is itself a context.</span>

+<span class="sd">&quot;&quot;&quot;This module provides code that allows one to pickle the state of a</span>
+<span class="sd">Python object to a dictionary.</span>
+
+<span class="sd">The motivation for this is simple.  The standard Python</span>
+<span class="sd">pickler/unpickler is best used to pickle simple objects and does not</span>
+<span class="sd">work too well for complex code.  Specifically, there are two major</span>
+<span class="sd">problems (1) the pickle file format is not easy to edit with a text</span>
+<span class="sd">editor and (2) when a pickle is unpickled, it creates all the</span>
+<span class="sd">necessary objects and sets the state of these objects.</span>
+
+<span class="sd">Issue (2) might not appear to be a problem.  However, often, the</span>
+<span class="sd">determination of the entire &#39;state&#39; of an application requires the</span>
+<span class="sd">knowledge of the state of many objects that are not really in the</span>
+<span class="sd">users concern.  The user would ideally like to pickle just what he</span>
+<span class="sd">thinks is relevant.  Now, given that the user is not going to save the</span>
+<span class="sd">entire state of the application, the use of pickle is insufficient</span>
+<span class="sd">since the state is no longer completely known (or worth knowing).  The</span>
+<span class="sd">default `Unpickler` recreates the objects and the typical</span>
+<span class="sd">implementation of `__setstate__` is usually to simply update the</span>
+<span class="sd">object&#39;s `__dict__` attribute.  This is inadequate because the pickled</span>
+<span class="sd">information is taken out of the real context when it was saved.</span>
+
+<span class="sd">The `StatePickler` basically pickles the &#39;state&#39; of an object into a</span>
+<span class="sd">large dictionary.  This pickled data may be easily unpickled and</span>
+<span class="sd">modified on the interpreter or edited with a text editor</span>
+<span class="sd">(`pprint.saferepr` is a friend).  The second problem is also</span>
+<span class="sd">eliminated.  When this state is unpickled using `StateUnpickler`, what</span>
+<span class="sd">you get is a special dictionary (a `State` instance).  This allows one</span>
+<span class="sd">to navigate the state just like the original object.  Its up to the</span>
+<span class="sd">user to create any new objects and set their states using this</span>
+<span class="sd">information.  This allows for a lot of flexibility while allowing one</span>
+<span class="sd">to save and set the state of (almost) any Python object.</span>
+
+<span class="sd">The `StateSetter` class helps set the state of a known instance.  When</span>
+<span class="sd">setting the state of an instance it checks to see if there is a</span>
+<span class="sd">`__set_pure_state__` method that in turn calls `StateSetter.set`</span>
+<span class="sd">appropriately.</span>
+
+<span class="sd">Additionally, there is support for versioning.  The class&#39; version is</span>
+<span class="sd">obtain from the `__version__` class attribute.  This version along</span>
+<span class="sd">with the versions of the bases of a class is embedded into the</span>
+<span class="sd">metadata of the state and stored.  By using `version_registry.py` a</span>
+<span class="sd">user may register a handler for a particular class and module.  When</span>
+<span class="sd">the state of an object is set using `StateSetter.set_state`, then</span>
+<span class="sd">these handlers are called in reverse order of their MRO.  This gives</span>
+<span class="sd">the handler an opportunity to upgrade the state depending on its</span>
+<span class="sd">version.  Builtin classes are not scanned for versions.  If a class</span>
+<span class="sd">has no version, then by default it is assumed to be -1.</span>
+
+
+<span class="sd">Example::</span>
+
+<span class="sd">  &gt;&gt;&gt; class A:</span>
+<span class="sd">  ...    def __init__(self):</span>
+<span class="sd">  ...        self.a = &#39;a&#39;</span>
+<span class="sd">  ...</span>
+<span class="sd">  &gt;&gt;&gt; a = A()</span>
+<span class="sd">  &gt;&gt;&gt; a.a = 100</span>
+<span class="sd">  &gt;&gt;&gt; import state_pickler</span>
+<span class="sd">  &gt;&gt;&gt; s = state_pickler.dumps(a)               # Dump the state of `a`.</span>
+<span class="sd">  &gt;&gt;&gt; state = state_pickler.loads_state(s)     # Get the state back.</span>
+<span class="sd">  &gt;&gt;&gt; b = state_pickler.create_instance(state) # Create the object.</span>
+<span class="sd">  &gt;&gt;&gt; state_pickler.set_state(b, state)        # Set the object&#39;s state.</span>
+<span class="sd">  &gt;&gt;&gt; assert b.a == 100</span>
+
+
+<span class="sd">Features</span>
+<span class="sd">--------</span>
+
+<span class="sd"> - The output is a plain old dictionary so is easy to parse, edit etc.</span>
+<span class="sd"> - Handles references to avoid duplication.</span>
+<span class="sd"> - Gzips Numeric arrays when dumping them.</span>
+<span class="sd"> - Support for versioning.</span>
+
+
+<span class="sd">Caveats</span>
+<span class="sd">-------</span>
+
+<span class="sd"> - Does not pickle a whole bunch of stuff including code objects and</span>
+<span class="sd">   functions.</span>
+<span class="sd"> - The output is a pure dictionary and does not contain instances.  So</span>
+<span class="sd">   using this *as it is* in `__setstate__` will not work.  Instead</span>
+<span class="sd">   define a `__set_pure_state__` and use the `StateSetter` class or</span>
+<span class="sd">   the `set_state` function provided by this module.</span>
+
+
+<span class="sd">Notes</span>
+<span class="sd">-----</span>
+
+<span class="sd">  Browsing the code from XMarshaL_ and pickle.py proved useful for</span>
+<span class="sd">  ideas.  None of the code is taken from there though.</span>

+<span class="sd">    will return the dictionary that is pickled.</span>

+<span class="sd">    etc. and also the actual object in the &#39;data&#39; key.  For example::</span>

+    <span class="sd">&quot;&quot;&quot;A preferences node that adds the notion of preferences scopes.</span>
+
+<span class="sd">    Scopes provide a way to access preferences in a precedence order, usually</span>
+<span class="sd">    depending on where they came from, for example from the command-line,</span>
+<span class="sd">    or set by the user in a preferences file, or the defaults (set by the</span>
+<span class="sd">    developer).</span>
+
+<span class="sd">    By default, this class provides two scopes - &#39;application&#39; which is</span>
+<span class="sd">    persistent and &#39;default&#39; which is not.</span>
+
+<span class="sd">    Path names passed to &#39;ScopedPreferences&#39; nodes can be either::</span>
+
+<span class="sd">        a) a preference path as used in a standard &#39;Preferences&#39; node, e.g::</span>
+
+<span class="sd">        &#39;acme.widget.bgcolor&#39;.</span>
+
+<span class="sd">        In this case the operation either takes place in the primary scope</span>
+<span class="sd">        (for operations such as &#39;set&#39; etc), or on all scopes in precedence</span>
+<span class="sd">        order (for operations such as &#39;get&#39; etc).</span>
+
+<span class="sd">        or</span>
+
+<span class="sd">        b) a preference path that refers to a specific scope e.g::</span>
+
+<span class="sd">        &#39;default/acme.widget.bgcolor&#39;</span>
+
+<span class="sd">        In this case the operation takes place *only* in the specified scope.</span>
+
+<span class="sd">    There is one drawback to this scheme. If you want to access a scope node</span>
+<span class="sd">    itself via the &#39;clear&#39;, &#39;keys&#39;, &#39;node&#39;, &#39;node_exists&#39; or &#39;node_names&#39;</span>
+<span class="sd">    methods then you have to append a trailing &#39;/&#39; to the path. Without that,</span>
+<span class="sd">    the node would try to perform the operation in the primary scope.</span>
+
+<span class="sd">    e.g. To get the names of the children of the &#39;application&#39; scope, use::</span>
+
+<span class="sd">        scoped.node_names(&#39;application/&#39;)</span>
+
+<span class="sd">    If you did this::</span>
+
+<span class="sd">        scoped.node_names(&#39;application&#39;)</span>
+
+<span class="sd">    Then the node would get the primary scope and try to find its child node</span>
+<span class="sd">    called &#39;application&#39;.</span>
+
+<span class="sd">    Of course you can just get the scope via::</span>
+
+<span class="sd">        application_scope = scoped.get_scope(&#39;application&#39;)</span>
+
+<span class="sd">    and then call whatever methods you like on it - which is definitely more</span>
+<span class="sd">    intentional and is highly recommended::</span>
+
+<span class="sd">        application_scope.node_names()</span>
+
+<span class="sd">    &quot;&quot;&quot;</span>

+<span class="sd">        to be items in the collection. Thus the first two signatures are safe</span>

+
+<span class="sd">        A trait attribute of type Map is called a *mapped* trait</span>

+
+<span class="sd">        In this example, the default value of the ``married`` attribute of the</span>

+<span class="sd">Defines the &#39;core&#39; traits for the Traits package. A trait is a type definition</span>
+<span class="sd">that can be used for normal Python object attributes, giving the attributes</span>
+<span class="sd">some additional characteristics:</span>
+
+<span class="sd">Initialization:</span>
+<span class="sd">    Traits have predefined values that do not need to be explicitly</span>
+<span class="sd">    initialized in the class constructor or elsewhere.</span>
+<span class="sd">Validation:</span>
+<span class="sd">    Trait attributes have flexible, type-checked values.</span>
+<span class="sd">Delegation:</span>
+<span class="sd">    Trait attributes&#39; values can be delegated to other objects.</span>
+<span class="sd">Notification:</span>
+<span class="sd">    Trait attributes can automatically notify interested parties when</span>
+<span class="sd">    their values change.</span>
+<span class="sd">Visualization:</span>
+<span class="sd">    Trait attributes can automatically construct (automatic or</span>
+<span class="sd">    programmer-defined) user interfaces that allow their values to be</span>
+<span class="sd">    edited or displayed)</span>
+
+<span class="sd">.. note:: &#39;trait&#39; is a synonym for &#39;property&#39;, but is used instead of the</span>
+<span class="sd">    word &#39;property&#39; to differentiate it from the Python language &#39;property&#39;</span>

+Preferences
+===========
+
+The preferences package provides a simple API for managing application
+preferences. The classes in the package are implemented using a layered
+approach where the lowest layer provides access to the raw preferences
+mechanism and each layer on top providing more convenient ways to get and set
+preference values.
+
+The Basic Preferences Mechanism
+-------------------------------
+
+Lets start by taking a look at the lowest layer which consists of the
+|IPreferences| interface and its default implementation in the |Preferences|
+class. This layer implements the basic preferences system which is a
+hierarchical arrangement of preferences 'nodes' (where each node is simply an
+object that implements the |IPreferences| interface). Nodes in the hierarchy can
+contain preference settings and/or child nodes. This layer also provides a
+default way to read and write preferences from the filesystem using the
+excellent `ConfigObj`_ package.
+
+This all sounds a bit complicated but, believe me, it isn't! To prove it
+(hopefully) lets look at an example. Say I have the following preferences in
+a file 'example.ini'::
+
+  [acme.ui]
+  bgcolor = blue
+  width = 50
+  ratio = 1.0
+  visible = True
+
+  [acme.ui.splash_screen]
+  image = splash
+  fgcolor = red
+
+I can create a preferences hierarchy from this file by::
+
+  >>> from apptools.preferences.api import Preferences
+  >>> preferences = Preferences(filename='example.ini')
+  >>> preferences.dump()
+
+   Node() {}
+     Node(acme) {}
+       Node(ui) {'bgcolor': 'blue', 'width': '50', 'ratio': '1.0', 'visible': 'True'}
+         Node(splash_screen) {'image': 'splash', 'fgcolor': 'red'}
+
+The 'dump' method (useful for debugging etc) simply 'pretty prints' a
+preferences hierarchy. The dictionary next to each node contains the node's
+actual preferences. In this case, the root node (the node with no name) is the
+preferences object that we created. This node now has one child node 'acme',
+which contains no preferences. The 'acme' node has one child, 'ui', which
+contains some preferences (e.g. 'bgcolor') and also a child node
+'splash_screen' which also contains preferences (e.g. 'image').
+
+To look up a preference we use::
+
+  >>> preferences.get('acme.ui.bgcolor')
+  'blue'
+
+If no such preferences exists then, by default, None is returned::
+
+  >>> preferences.get('acme.ui.bogus') is None
+  True
+
+You can also specify an explicit default value::
+
+  >>> preferences.get('acme.ui.bogus', 'fred')
+  'fred'
+
+To set a preference we use::
+
+  >>> preferences.set('acme.ui.bgcolor', 'red')
+  >>> preferences.get('acme.ui.bgcolor')
+  'red'
+
+And to make sure the preferences are saved back to disk::
+
+  >>> preferences.flush()
+
+To add a new preference value we simply set it::
+
+  >>> preferences.set('acme.ui.fgcolor', 'black')
+  >>> preferences.get('acme.ui.fgcolor')
+  'black'
+
+Any missing nodes in a call to 'set' are created automatically, hence::
+
+  >>> preferences.set('acme.ui.button.fgcolor', 'white')
+  >>> preferences.get('acme.ui.button.fgcolor')
+  'white'
+
+Preferences can also be 'inherited'. e.g. Notice that the 'splash_screen'
+node does not contain a 'bgcolor' preference, and hence::
+
+   >>> preferences.get('acme.ui.splash_screen.bgcolor') is None
+   True
+
+But if we allow the 'inheritance' of preference values then::
+
+   >>> preferences.get('acme.ui.splash_screen.bgcolor', inherit=True)
+   'red'
+
+By using 'inheritance' here the preferences system will try the following
+preferences::
+
+  'acme.ui.splash_screen.bgcolor'
+  'acme.ui.bgcolor'
+  'acme.bgcolor'
+  'bgcolor'
+
+Strings, Glorious Strings
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+At this point it is worth mentioning that preferences are *always* stored and
+returned as strings. This is because of the limitations of the traditional
+'.ini' file format i.e. they don't contain any type information! Now before you
+start panicking, this doesn't mean that all of your preferences have to be
+strings! Currently the preferences system allows, strings(!), booleans, ints,
+longs, floats and complex numbers. When you store a non-string value it gets
+converted to a string for you, but you *always* get a string back::
+
+  >>> preferences.get('acme.ui.width')
+  '50'
+  >>> preferences.set('acme.ui.width', 100)
+  >>> preferences.get('acme.ui.width')
+  '100'
+
+  >>> preferences.get('acme.ui.visible')
+  'True'
+  >>> preferences.set('acme.ui.visible', False)
+  >>> preferences.get('acme.ui.visible')
+  'False'
+
+This is obviously not terribly convenient, and so the following section
+discusses how we associate type information with our preferences to make
+getting and setting them more natural.
+
+Preferences and Types
+---------------------
+
+As mentioned previously, we would like to be able to get and set non-string
+preferences in a more convenient way. This is where the |PreferencesHelper|
+class comes in.
+
+Let's take another look at 'example.ini'::
+
+  [acme.ui]
+  bgcolor = blue
+  width = 50
+  ratio = 1.0
+  visible = True
+
+  [acme.ui.splash_screen]
+  image = splash
+  fgcolor = red
+
+Say, I am interested in the preferences in the 'acme.ui' section. I can use a
+preferences helper as follows::
+
+  from apptools.preferences.api import PreferencesHelper
+
+  class SplashScreenPreferences(PreferencesHelper):
+      """ A preferences helper for the splash screen. """
+
+      preferences_path = 'acme.ui'
+
+      bgcolor = Str
+      width   = Int
+      ratio   = Float
+      visible = Bool
+
+  >>> preferences = Preferences(filename='example.ini')
+  >>> helper = SplashScreenPreferences(preferences=preferences)
+  >>> helper.bgcolor
+  'blue'
+  >>> helper.width
+  50
+  >>> helper.ratio
+  1.0
+  >>> helper.visible
+  True
+
+And, obviously, I can set the value of the preferences via the helper too::
+
+  >>> helper.ratio = 0.5
+
+And if you want to prove to yourself it really did set the preference::
+
+  >>> preferences.get('acme.ui.ratio')
+  '0.5'
+
+Using a preferences helper you also get notified via the usual trait
+mechanism when the preferences are changed (either via the helper or via the
+preferences node directly::
+
+  def listener(obj, trait_name, old, new):
+      print(trait_name, old, new)
+
+  >>> helper.on_trait_change(listener)
+  >>> helper.ratio = 0.75
+  ratio 0.5 0.75
+  >>> preferences.set('acme.ui.ratio', 0.33)
+  ratio 0.75 0.33
+
+Scoped Preferences
+------------------
+
+In many applications the idea of preferences scopes is useful. In a scoped
+system, an actual preference value can be stored in any scope and when a call
+is made to the 'get' method the scopes are searched in order of precedence.
+
+The default implementation (in the |ScopedPreferences| class) provides two
+scopes by default:
+
+1) The application scope
+
+This scope stores itself in the 'ETSConfig.application_home' directory. This
+scope is generally used when *setting* any user preferences.
+
+2) The default scope
+
+This scope is transient (i.e. it does not store itself anywhere). This scope
+is generally used to load any predefined default values into the preferences
+system.
+
+If you are happy with the default arrangement, then using the scoped
+preferences is just like using the plain old non-scoped version::
+
+  >>> from apptools.preferences.api import ScopedPreferences
+  >>> preferences = ScopedPreferences(filename='example.ini')
+  >>> preferences.load('example.ini')
+  >>> preferences.dump()
+
+   Node() {}
+     Node(application) {}
+       Node(acme) {}
+         Node(ui) {'bgcolor': 'blue', 'width': '50', 'ratio': '1.0', 'visible': 'True'}
+           Node(splash_screen) {'image': 'splash', 'fgcolor': 'red'}
+     Node(default) {}
+
+Here you can see that the root node now has a child node representing each
+scope.
+
+When we are getting and setting preferences using scopes we generally want the
+following behaviour:
+
+a) When we get a preference we want to look it up in each scope in order. The
+first scope that contains a value 'wins'.
+
+b) When we set a preference, we want to set it in the first scope. By default
+this means that when we set a preference it will be set in the application
+scope. This is exactly what we want as the application scope is the scope that
+is persistent.
+
+So usually, we just use the scoped preferences as before::
+
+  >>> preferences.get('acme.ui.bgcolor')
+  'blue'
+  >>> preferences.set('acme.ui.bgcolor', 'red')
+  >>> preferences.dump()
+
+   Node() {}
+     Node(application) {}
+       Node(acme) {}
+         Node(ui) {'bgcolor': 'red', 'width': '50', 'ratio': '1.0', 'visible': 'True'}
+           Node(splash_screen) {'image': 'splash', 'fgcolor': 'red'}
+     Node(default) {}
+
+And, conveniently, preference helpers work just the same with scoped
+preferences too::
+
+  >>> helper = SplashScreenPreferences(preferences=preferences)
+  >>> helper.bgcolor
+  'red'
+  >>> helper.width
+  50
+  >>> helper.ratio
+  1.0
+  >>> helper.visible
+  True
+
+Accessing a particular scope
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Should you care about getting or setting a preference in a particular scope
+then you use the following syntax::
+
+  >>> preferences.set('default/acme.ui.bgcolor', 'red')
+  >>> preferences.get('default/acme.ui.bgcolor')
+  'red'
+  >>> preferences.dump()
+
+   Node() {}
+     Node(application) {}
+       Node(acme) {}
+         Node(ui) {'bgcolor': 'red', 'width': '50', 'ratio': '1.0', 'visible': 'True'}
+           Node(splash_screen) {'image': 'splash', 'fgcolor': 'red'}
+     Node(default) {}
+       Node(acme) {}
+         Node(ui) {'bgcolor': 'red'}
+
+You can also get hold of a scope via::
+
+  >>> default = preferences.get_scope('default')
+
+And then perform any of the usual operations on it.

+
+Preferences in Envisage
+=======================
+
+This section discusses how an Envisage application uses the preferences
+mechanism. Envisage tries not to dictate too much, and so this describes the
+default behaviour, but you are free to override it as desired.
+
+Envisage uses the default implementation of the |ScopedPreferences| class which
+is made available via the application's 'preferences' trait::
+
+  >>> application = Application(id='myapplication')
+  >>> application.preferences.set('acme.ui.bgcolor', 'yellow')
+  >>> application.preferences.get('acme.ui.bgcolor')
+  'yellow'
+
+Hence, you use the Envisage preferences just like you would any other scoped
+preferences.
+
+It also registers itself as the default preferences node used by the
+|PreferencesHelper| class. Hence you don't need to provide a preferences node
+explicitly to your helper::
+
+  >>> helper = SplashScreenPreferences()
+  >>> helper.bgcolor
+  'blue'
+  >>> helper.width
+  100
+  >>> helper.ratio
+  1.0
+  >>> helper.visible
+  True
+
+The only extra thing that Envisage does for you is to provide an extension
+point that allows you to contribute any number of '.ini' files that are
+loaded into the default scope when the application is started.
+
+e.g. To contribute a preference file for my plugin I might use::
+
+  class MyPlugin(Plugin):
+      ...
+
+      @contributes_to('envisage.preferences')
+      def get_preferences(self, application):
+          return ['pkgfile://mypackage:preferences.ini']

+Automatic script recording
+===========================
+
+This package provides a very handy and powerful Python script recording
+facility.  This can be used to:
+
+ - record all actions performed on a traits based UI into a *human
+   readable*, Python script that should be able to recreate your UI
+   actions.
+
+ - easily learn the scripting API of an application.
+
+This package is not just a toy framework and is powerful enough to
+provide full script recording to the Mayavi_ application.  Mayavi is a
+powerful 3D visualization tool that is part of ETS_.

+.. _ETS: https://docs.enthought.com/ets/
+
+.. _scripting-api:
+
+
+The scripting API
+------------------
+
+The scripting API primarily allows you to record UI actions for objects
+that have Traits.  Technically the framework listens to all trait
+changes so will work outside a UI.  We do not document the full API
+here, the best place to look for that is the
+``apptools.scripting.recorder`` module which is reasonably well
+documented.  We provide a high level overview of the library.
+
+The quickest way to get started is to look at a small example.
+
+
+.. _scripting-api-example:
+
+A tour by example
+~~~~~~~~~~~~~~~~~~~
+
+The following example is taken from the test suite.  Consider a set of
+simple objects organized in a hierarchy::
+
+    from traits.api import (HasTraits, Float, Instance,
+            Str, List, Bool, HasStrictTraits, Tuple, PrefixMap, Range,
+            Trait)
+    from apptools.scripting.api import (Recorder, recordable,
+        set_recorder)
+
+    class Property(HasStrictTraits):
+        color = Tuple(Range(0.0, 1.0), Range(0.0, 1.0), Range(0.0, 1.0))
+        opacity = Range(0.0, 1.0, 1.0)
+        representation = PrefixMap(
+            {"surface": 2, "wireframe": 1, "points": 0},
+            default_value="surface"
+        )
+
+    class Toy(HasTraits):
+        color = Str
+        type = Str
+        # Note the use of the trait metadata to ignore this trait.
+        ignore = Bool(False, record=False)
+
+    class Child(HasTraits):
+        name = Str('child')
+        age = Float(10.0)
+        # The recorder walks through sub-instances if they are marked
+        # with record=True
+        property = Instance(Property, (), record=True)
+        toy = Instance(Toy, record=True)
+        friends = List(Str)
+
+        # The decorator records the method.
+        @recordable
+        def grow(self, x):
+            """Increase age by x years."""
+            self.age += x
+
+    class Parent(HasTraits):
+        children = List(Child, record=True)
+        recorder = Instance(Recorder, record=False)
+
+Using these simple classes we first create a simple object hierarchy as
+follows::
+
+    p = Parent()
+    c = Child()
+    t = Toy()
+    c.toy = t
+    p.children.append(c)
+
+Given this hierarchy, we'd like to be able to record a script.  To do
+this we setup the recording infrastructure::
+
+    from mayavi.core.recorder import Recorder, set_recorder
+    # Create a recorder.
+    r = Recorder()
+    # Set the global recorder so the decorator works.
+    set_recorder(r)
+    r.register(p)
+    r.recording = True
+
+The key method here is the ``r.register(p)`` call above.  It looks at
+the traits of ``p`` and finds all traits and nested objects that specify
+a ``record=True`` in their trait metadata (all methods starting and
+ending with ``_`` are ignored).  All sub-objects are in turn registered
+with the recorder and so on.  Callbacks are attached to traits changes
+and these are wired up to produce readable and executable code.  The
+``set_recorder(r)`` call is also very important and sets the global
+recorder so the framework listens to any functions that are decorated
+with the ``recordable`` decorator.
+
+Now lets test this out like so::
+
+    # The following will be recorded.
+    c.name = 'Shiva'
+    c.property.representation = 'w'
+    c.property.opacity = 0.4
+    c.grow(1)
+
+To see what's been recorded do this::
+
+    print(r.script)
+
+This prints::
+
+    child = parent.children[0]
+    child.name = 'Shiva'
+    child.property.representation = 'wireframe'
+    child.property.opacity = 0.40000000000000002
+    child.grow(1)
+
+The recorder internally maintains a mapping between objects and unique
+names for each object.  It also stores the information about the
+location of a particular object in the object hierarchy.  For example,
+the path to the ``Toy`` instance in the hierarchy above is
+``parent.children[0].toy``.  Since scripting with lists this way can be
+tedious, the recorder first instantiates the ``child``::
+
+    child = parent.children[0]
+
+Subsequent lines use the ``child`` attribute.  The recorder always tries
+to instantiate the object referred to using its path information in this
+manner.
+
+To record a function or method call one must simply decorate the
+function/method with the ``recordable`` decorator.  Nested recordable
+functions are not recorded and trait changes are also not recorded if
+done inside a recordable function.
+
+.. note::
+
+    1. It is very important to note that the global recorder must be set
+       via the ``set_recorder`` method.  The ``recordable`` decorator
+       relies on this being set to work.
+
+    2. The ``recordable`` decorator will work with plain Python classes
+       and with functions too.
+
+To stop recording do this::
+
+    r.unregister(p)
+    r.recording = False
+
+The ``r.unregister(p)`` reverses the ``r.register(p)`` call and
+unregisters all nested objects as well.
+
+
+.. _recorder-advanced-uses:
+
+Advanced use cases
+~~~~~~~~~~~~~~~~~~~~
+
+Here are a few advanced use cases.
+
+ - The API also provides a ``RecorderWithUI`` class that provides a
+   simple user interface that prints the recorded script and allows the
+   user to save the script.
+
+ - Sometimes it is not enough to just record trait changes, one may want
+   to pass an arbitrary string or command when recording is occurring.
+   To allow for this, if one defines a ``recorder`` trait on the object,
+   it is set to the current recorder.  One can then use this recorder to
+   do whatever one wants.  This is very convenient.
+
+ - To ignore specific traits one must specify either a ``record=False``
+   metadata to the trait definition or specify a list of strings to the
+   ``register`` method in the ``ignore`` keyword argument.
+
+ - If you want to use a specific name for an object on the script you
+   can pass the ``script_id`` parameter to the register function.
+
+
+For more details on the recorder itself we suggest reading the module
+source code.  It is fairly well documented and with the above background
+should be enough to get you going.

+.. _selection_service:
+
+The selection service
+=====================
+
+It is quite common in GUI applications to have a UI element displaying a
+collection of items that a user can select ("selection providers"), while
+other parts of the application must react to changes in the selection
+("selection listeners").
+
+Ideally, the listeners would not have a direct dependency on the UI object.
+This is especially important in extensible `envisage`_ applications, where
+a plugin might need to react to a selection change, but we do not want to
+expose the internal organization of the application to external developers.
+
+This package defines a selection service that manages the communication
+between providers and listener.
+
+
+The :class:`~.SelectionService` object
+--------------------------------------
+
+The :class:`~.SelectionService` object is the central manager that handles
+the communication between selection providers and listener.
+
+:ref:`Selection providers <selection_providers>` are components that wish to
+publish information about their current selection for public consumption.
+They register to a selection
+service instance when they first have a selection available (e.g., when the
+UI showing a list of selectable items is initialized), and un-register as soon
+as the selection is not available anymore (e.g., the UI is destroyed when the
+windows is closed).
+
+:ref:`Selection listeners <selection_listeners>` can query the selection
+service to get the current selection published by a provider, using the
+provider unique ID.
+
+The service acts as a broker between providers and listeners, making sure that
+they are notified when the
+:attr:`~apptools.selection.i_selection_provider.ISelectionProvider.selection`
+event is fired.
+
+.. _selection_providers:
+
+Selection providers
+-------------------
+
+Any object can become a selection provider by implementing the
+:class:`~apptools.selection.i_selection_provider.ISelectionProvider`
+interface, and registering to the selection service.
+
+Selection providers must provide a unique ID
+:attr:`~apptools.selection.i_selection_provider.ISelectionProvider.provider_id`,
+which is used by listeners to request its current selection.
+
+Whenever its selection changes, providers fire a
+:attr:`~apptools.selection.i_selection_provider.ISelectionProvider.selection`
+event. The content of the event is an instance implementing
+:class:`~.ISelection` that contains information about the selected items.
+For example, a :class:`~.ListSelection` object contains a list of selected
+items, and their indices.
+
+Selection providers can also be queried directly about their current selection
+using the
+:attr:`~apptools.selection.i_selection_provider.ISelectionProvider.get_selection`
+method, and can be requested to change their selection to a new one with the
+:attr:`~apptools.selection.i_selection_provider.ISelectionProvider.set_selection`
+method.
+
+Registration
+~~~~~~~~~~~~
+
+Selection providers publish their selection by registering to the selection
+service using the
+:attr:`~apptools.selection.selection_service.SelectionService.add_selection_provider`
+method. When the selection is no longer available, selection providers
+should un-register through
+:attr:`~apptools.selection.selection_service.SelectionService.remove_selection_provider`.
+
+Typically, selection providers are UI objects showing a list or tree of items,
+they register as soon as the UI component is initialized, and un-register
+when the UI component disappears (e.g., because their window has been closed).
+In more complex applications, the registration could be done by a controller
+object instead.
+
+.. _selection_listeners:
+
+Selection listeners
+-------------------
+
+Selection listeners request information regarding the current selection
+of a selection provider given their provider ID. The :class:`~.SelectionService`
+supports two distinct use cases:
+
+ 1) Passively listening to selection changes: listener connect to a specific
+    provider and are notified when the provider's selection changes.
+
+ 2) Actively querying a provider for its current selection: the selection
+    service can be used to query a provider using its unique ID.
+
+Passive listening
+~~~~~~~~~~~~~~~~~
+
+Listeners connect to the selection events for a given provider using the
+:attr:`~apptools.selection.selection_service.SelectionService.connect_selection_listener`
+method. They need to provide the unique ID of the provider, and a function
+(or callable) that is called to send the event. This callback function takes
+one argument, an implementation of the :class:`~.ISelection` that represents
+the selection.
+
+It is possible for a listener to connect to a provider ID before it is
+registered. As soon as the provider is registered, the listener will receive
+a notification containing the provider's initial selection.
+
+To disconnect a listener use the methods
+:attr:`~apptools.selection.selection_service.SelectionService.disconnect_selection_listener`.
+
+Active querying
+~~~~~~~~~~~~~~~
+
+In other instances, an element of the application only needs the current
+selection at a specific time. For example, a toolbar button could open dialog
+representing a user action based on what is currently selected in the active
+editor.
+
+The
+:attr:`~apptools.selection.selection_service.SelectionService.get_selection`
+method calls the corresponding method on the provider with the given ID and
+returns an :class:`~.ISelection` instance.
+
+Setting a selection
+~~~~~~~~~~~~~~~~~~~
+
+Finally, it is possible to request a provider to set its selection to a given
+set of objects with
+:attr:`~apptools.selection.selection_service.SelectionService.set_selection`.
+The main use case for this method is multiple views of the same list of
+objects, which need to keep their selection synchronized.
+
+If the items specified in the arguments are not available in the provider,
+a :class:`~apptools.selection.errors.ProviderNotRegisteredError` is raised,
+unless the optional keyword argument :attr:`ignore_missing` is set to ``True``.

+Undo Framework
+==============
+
+.. warning:: 
+    apptools.undo has been deprecated and moved to
+    `Pyface <https://github.com/enthought/pyface>`_. It will be removed in a
+    future release. Please use `pyface.undo <https://docs.enthought.com/pyface/undo.html>`_
+    instead.
+
+The Undo Framework is a component of the Enthought Tool Suite that provides
+developers with an API that implements the standard pattern for do/undo/redo
+commands.
+
+The framework is completely configurable.  Alternate implementations of all
+major components can be provided if necessary.
+
+
+Framework Concepts
+------------------
+
+The following are the concepts supported by the framework.
+
+- Command
+
+  A command is an application defined operation that can be done (i.e.
+  executed), undone (i.e. reverted) and redone (i.e. repeated).
+
+  A command operates on some data and maintains sufficient state to allow it to
+  revert or repeat a change to the data.
+
+  Commands may be merged so that potentially long sequences of similar
+  commands (e.g. to add a character to some text) can be collapsed into a
+  single command (e.g. to add a word to some text).
+
+- Macro
+
+  A macro is a sequence of commands that is treated as a single command when
+  being undone or redone.
+
+- Command Stack
+
+  A command is done by pushing it onto a command stack.  The last command can
+  be undone and redone by calling appropriate command stack methods.  It is
+  also possible to move the stack's position to any point and the command stack
+  will ensure that commands are undone or redone as required.
+
+  A command stack maintains a *clean* state which is updated as commands are
+  done and undone.  It may be explicitly set, for example when the data being
+  manipulated by the commands is saved to disk.
+
+  Canned PyFace actions are provided as wrappers around command stack methods
+  to implement common menu items.
+
+- Undo Manager
+
+  An undo manager is responsible for one or more command stacks and maintains
+  a reference to the currently active stack.  It provides convenience undo and
+  redo methods that operate on the currently active stack.
+
+  An undo manager ensures that each command execution is allocated a unique
+  sequence number, irrespective of which command stack it is pushed to.  Using
+  this it is possible to synchronise multiple command stacks and restore them
+  to a particular point in time.
+
+  An undo manager will generate an event whenever the clean state of the active
+  stack changes.  This can be used to maintain some sort of GUI status
+  indicator to tell the user that their data has been modified since it was
+  last saved.
+
+Typically an application will have one undo manager and one undo stack for
+each data type that can be edited.  However this is not a requirement: how the
+command stack's in particular are organised and linked (with the user
+manager's sequence number) can need careful thought so as not to confuse the
+user - particularly in a plugin based application that may have many editors.
+
+To support this typical usage the PyFace ``Workbench`` class has an
+``undo_manager`` trait and the PyFace ``Editor`` class has a ``command_stack``
+trait.  Both are lazy loaded so can be completely ignored if they are not used.
+
+
+API Overview
+------------
+
+This section gives a brief overview of the various classes implemented in the
+framework.  The complete API_ documentation is available as endo generated
+HTML.
+
+The example_ application demonstrates all the major features of the framework.
+
+
+UndoManager
+...........
+
+The ``UndoManager`` class is the default implementation of the ``IUndoManager``
+interface.
+
+``active_stack``
+    This trait is a reference to the currently active command stack and may be
+    None.  Typically it is set when some sort of editor becomes active.
+
+``active_stack_clean``
+    This boolean trait reflects the clean state of the currently active
+    command stack.  It is intended to support a "document modified" indicator
+    in the GUI.  It is maintained by the undo manager.
+
+``stack_updated``
+    This event is fired when the index of a command stack is changed.  A
+    reference to the stack is passed as an argument to the event and may not
+    be the currently active stack.
+
+``undo_name``
+    This Str trait is the name of the command that can be undone, and will
+    be empty if there is no such command.  It is maintained by the undo
+    manager.
+
+``redo_name``
+    This Str trait is the name of the command that can be redone, and will
+    be empty if there is no such command.  It is maintained by the undo
+    manager.
+
+``sequence_nr``
+    This integer trait is the sequence number of the next command to be
+    executed.  It is incremented immediately before a command's ``do()``
+    method is called.  A particular sequence number identifies the state of
+    all command stacks handled by the undo manager and allows those stacks to
+    be set to the point they were at at a particular point in time.  In other
+    words, the sequence number allows otherwise independent command stacks to
+    be synchronised.
+
+``undo()``
+    This method calls the ``undo()`` method of the last command on the active
+    command stack.
+
+``redo()``
+    This method calls the ``redo()`` method of the last undone command on the
+    active command stack.
+
+
+CommandStack
+............
+
+The ``CommandStack`` class is the default implementation of the
+``ICommandStack`` interface.
+
+``clean``
+    This boolean traits reflects the clean state of the command stack.  Its
+    value changes as commands are executed, undone and redone.  It may also be
+    explicitly set to mark the current stack position as being clean (when
+    data is saved to disk for example).
+
+``undo_name``
+    This Str trait is the name of the command that can be undone, and will
+    be empty if there is no such command.  It is maintained by the command
+    stack.
+
+``redo_name``
+    This Str trait is the name of the command that can be redone, and will
+    be empty if there is no such command.  It is maintained by the command
+    stack.
+
+``undo_manager``
+    This trait is a reference to the undo manager that manages the command
+    stack.
+
+``push(command)``
+    This method executes the given command by calling its ``do()`` method.
+    Any value returned by ``do()`` is returned by ``push()``.  If the command
+    couldn't be merged with the previous one then it is saved on the command
+    stack.
+
+``undo(sequence_nr=0)``
+    This method undoes the last command.  If a sequence number is given then
+    all commands are undone up to an including the sequence number.
+
+``redo(sequence_nr=0)``
+    This method redoes the last command and returns any result.  If a sequence
+    number is given then all commands are redone up to an including the
+    sequence number and any result of the last of these is returned.
+
+``clear()``
+    This method clears the command stack, without undoing or redoing any
+    commands, and leaves the stack in a clean state.  It is typically used
+    when all changes to the data have been abandoned.
+
+``begin_macro(name)``
+    This method begins a macro by creating an empty command with the given
+    name.  The commands passed to all subsequent calls to ``push()`` will be
+    contained in the macro until the next call to ``end_macro()``.  Macros may
+    be nested.  The command stack is disabled (ie. nothing can be undone or
+    redone) while a macro is being created (ie. while there is an outstanding
+    ``end_macro()`` call).
+
+``end_macro()``
+    This method ends the current macro.
+
+
+ICommand
+........

+The ``ICommand`` interface defines the interface that must be implemented by
+any undoable/redoable command.
+
+``data``
+    This optional trait is a reference to the data object that the command
+    operates on.  It is not used by the framework itself.
+
+``name``
+    This Str trait is the name of the command as it will appear in any GUI
+    element (e.g. in the text of an undo and redo menu entry).  It may include
+    ``&`` to indicate a keyboard shortcut which will be automatically removed
+    whenever it is inappropriate.
+
+``__init__(*args)``
+    If the command takes arguments then the command must ensure that deep
+    copies should be made if appropriate.
+
+``do()``
+    This method is called by a command stack to execute the command and to
+    return any result.  The command must save any state necessary for the
+    ``undo()`` and ``redo()`` methods to work.  It is guaranteed that this
+    will only ever be called once and that it will be called before any call
+    to ``undo()`` or ``redo()``.
+
+``undo()``
+    This method is called by a command stack to undo the command.
+
+``redo()``
+    This method is called by a command stack to redo the command and to return
+    any result.
+
+``merge(other)``
+    This method is called by the command stack to try and merge the ``other``
+    command with this one.  True should be returned if the commands were
+    merged.  If the commands are merged then ``other`` will not be placed on
+    the command stack.  A subsequent undo or redo of this modified command
+    must have the same effect as the two original commands.
+
+
+AbstractCommand
+...............
+
+``AbstractCommand`` is an abstract base class that implements the ``ICommand``
+interface.  It provides a default implementation of the ``merge()`` method.
+
+
+CommandAction
+.............
+
+The ``CommandAction`` class is a sub-class of the PyFace ``Action`` class that
+is used to wrap commands.
+
+``command``
+    This callable trait must be set to a factory that will return an object
+    that implements ``ICommand``.  It will be called when the action is invoked
+    and the object created pushed onto the command stack.
+
+``command_stack``
+    This instance trait must be set to the command stack that commands invoked
+    by the action are pushed to.
+
+``data``
+    This optional trait is a reference to the data object that will be passed
+    to the ``command`` factory when it is called.
+
+
+UndoAction
+..........
+
+The ``UndoAction`` class is a canned PyFace action that undoes the last
+command of the active command stack.
+
+
+RedoAction
+..........
+
+The ``RedoAction`` class is a canned PyFace action that redoes the last
+command undone of the active command stack.

+//	1. Enforce API surface and semantic compatibility with 1.9.x branch
+//	2. Improve the module's maintainability by reducing the storage
+//		paths to a single mechanism.
+//	3. Use the same single mechanism to support "private" and "user" data.
+//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
+//	5. Avoid exposing implementation details on user objects (eg. expando properties)
+//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

+<p>If the value is &lt;= 0, the column will have a <em>default</em> width, which is
+the same as specifying a width of 0.1.</p>
+<p>If the value is &gt; 1.0, it is converted to an integer and the result is
+the width of the column in pixels. This is referred to as a
+<em>fixed width</em> column.</p>
+<p>If the value is a float such that 0.0 &lt; value &lt;= 1.0, it is treated as
+the <em>unnormalized fraction of the available space</em> that is to be
+assigned to the column. What this means requires a little explanation.</p>
+<p>To arrive at the size in pixels of the column at any given time, the
+editor adds together all of the <em>unnormalized fraction</em> values
+returned for all columns in the table to arrive at a total value. Each
+<em>unnormalized fraction</em> is then divided by the total to create a
+<em>normalized fraction</em>. Each column is then assigned an amount of space
+in pixels equal to the maximum of 30 or its <em>normalized fraction</em>
+multiplied by the <em>available space</em>. The <em>available space</em> is defined
+as the actual width of the table minus the width of all <em>fixed width</em>
+columns. Note that this calculation is performed each time the table is
+resized in the user interface, thus allowing columns of this type to
+increase or decrease their width dynamically, while leaving <em>fixed
+width</em> columns unchanged.</p>

+<p>Provider of a framework that dynamically determines the contents of a
+context at the time of interaction with the contents rather than at the
+time a class is written.</p>
+<p>This capability is particularly useful when the object acting as a context
+is part of a plug-in application – such as Envisage.  In general, this
+capability allows the context to be:</p>
+<ul class="simple">
+<li><p>Extendable by contributions from somewhere other than the original
+code writer</p></li>
+<li><p>Dynamic in that the elements it is composed of can change each time
+someone interacts with the contents of the context.</p></li>
+</ul>
+<p>It should be noted that this capability is explicitly different from
+contexts that look at another container to determine their contents, such
+as a file system context!</p>
+<p>Users of this framework contribute items to a dynamic context by adding
+traits to the dynamic context instance.  (This addition can happen
+statically through the use of a Traits Category.)  The trait value is the
+context item’s value and the trait definition’s metadata determines how the
+item is treated within the context.  The support metadata is:</p>
+<dl class="simple">
+<dt>context_name: A non-empty string</dt><dd><p>Represents the name of the item within this context.  This must be
+present for the trait to show up as a context item though the value
+may change over time as the item gets bound to different names.</p>
+</dd>
+<dt>context_order: A float value</dt><dd><p>Indicates the position for the item within this context.  All
+dynamically contributed context items are sorted by ascending order
+of this value using the standard list sort function.</p>
+</dd>
+<dt>is_context: A boolean value</dt><dd><p>True if the item is itself a context.</p>
+</dd>

+<p>This module provides code that allows one to pickle the state of a
+Python object to a dictionary.</p>
+<p>The motivation for this is simple.  The standard Python
+pickler/unpickler is best used to pickle simple objects and does not
+work too well for complex code.  Specifically, there are two major
+problems (1) the pickle file format is not easy to edit with a text
+editor and (2) when a pickle is unpickled, it creates all the
+necessary objects and sets the state of these objects.</p>
+<p>Issue (2) might not appear to be a problem.  However, often, the
+determination of the entire ‘state’ of an application requires the
+knowledge of the state of many objects that are not really in the
+users concern.  The user would ideally like to pickle just what he
+thinks is relevant.  Now, given that the user is not going to save the
+entire state of the application, the use of pickle is insufficient
+since the state is no longer completely known (or worth knowing).  The
+default <cite>Unpickler</cite> recreates the objects and the typical
+implementation of <cite>__setstate__</cite> is usually to simply update the
+object’s <cite>__dict__</cite> attribute.  This is inadequate because the pickled
+information is taken out of the real context when it was saved.</p>
+<p>The <cite>StatePickler</cite> basically pickles the ‘state’ of an object into a
+large dictionary.  This pickled data may be easily unpickled and
+modified on the interpreter or edited with a text editor
+(<cite>pprint.saferepr</cite> is a friend).  The second problem is also
+eliminated.  When this state is unpickled using <cite>StateUnpickler</cite>, what
+you get is a special dictionary (a <cite>State</cite> instance).  This allows one
+to navigate the state just like the original object.  Its up to the
+user to create any new objects and set their states using this
+information.  This allows for a lot of flexibility while allowing one
+to save and set the state of (almost) any Python object.</p>
+<p>The <cite>StateSetter</cite> class helps set the state of a known instance.  When
+setting the state of an instance it checks to see if there is a
+<cite>__set_pure_state__</cite> method that in turn calls <cite>StateSetter.set</cite>
+appropriately.</p>
+<p>Additionally, there is support for versioning.  The class’ version is
+obtain from the <cite>__version__</cite> class attribute.  This version along
+with the versions of the bases of a class is embedded into the
+metadata of the state and stored.  By using <cite>version_registry.py</cite> a
+user may register a handler for a particular class and module.  When
+the state of an object is set using <cite>StateSetter.set_state</cite>, then
+these handlers are called in reverse order of their MRO.  This gives
+the handler an opportunity to upgrade the state depending on its
+version.  Builtin classes are not scanned for versions.  If a class
+has no version, then by default it is assumed to be -1.</p>

+<p>There is one drawback to this scheme. If you want to access a scope node
+itself via the ‘clear’, ‘keys’, ‘node’, ‘node_exists’ or ‘node_names’
+methods then you have to append a trailing ‘/’ to the path. Without that,
+the node would try to perform the operation in the primary scope.</p>
+<p>e.g. To get the names of the children of the ‘application’ scope, use:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">scoped</span><span class="o">.</span><span class="n">node_names</span><span class="p">(</span><span class="s1">&#39;application/&#39;</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>If you did this:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">scoped</span><span class="o">.</span><span class="n">node_names</span><span class="p">(</span><span class="s1">&#39;application&#39;</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>Then the node would get the primary scope and try to find its child node
+called ‘application’.</p>
+<p>Of course you can just get the scope via:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">application_scope</span> <span class="o">=</span> <span class="n">scoped</span><span class="o">.</span><span class="n">get_scope</span><span class="p">(</span><span class="s1">&#39;application&#39;</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>and then call whatever methods you like on it - which is definitely more
+intentional and is highly recommended:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">application_scope</span><span class="o">.</span><span class="n">node_names</span><span class="p">()</span>

+<h1>Preferences<a class="headerlink" href="#preferences" title="Permalink to this headline">¶</a></h1>
+<p>The preferences package provides a simple API for managing application
+preferences. The classes in the package are implemented using a layered
+approach where the lowest layer provides access to the raw preferences
+mechanism and each layer on top providing more convenient ways to get and set
+preference values.</p>
+<div class="section" id="the-basic-preferences-mechanism">
+<h2>The Basic Preferences Mechanism<a class="headerlink" href="#the-basic-preferences-mechanism" title="Permalink to this headline">¶</a></h2>
+<p>Lets start by taking a look at the lowest layer which consists of the
+<a class="reference internal" href="../api/apptools.preferences.i_preferences.html#apptools.preferences.i_preferences.IPreferences" title="apptools.preferences.i_preferences.IPreferences"><code class="xref py py-class docutils literal notranslate"><span class="pre">IPreferences</span></code></a> interface and its default implementation in the <a class="reference internal" href="../api/apptools.preferences.preferences.html#apptools.preferences.preferences.Preferences" title="apptools.preferences.preferences.Preferences"><code class="xref py py-class docutils literal notranslate"><span class="pre">Preferences</span></code></a>
+class. This layer implements the basic preferences system which is a
+hierarchical arrangement of preferences ‘nodes’ (where each node is simply an
+object that implements the <a class="reference internal" href="../api/apptools.preferences.i_preferences.html#apptools.preferences.i_preferences.IPreferences" title="apptools.preferences.i_preferences.IPreferences"><code class="xref py py-class docutils literal notranslate"><span class="pre">IPreferences</span></code></a> interface). Nodes in the hierarchy can
+contain preference settings and/or child nodes. This layer also provides a
+default way to read and write preferences from the filesystem using the
+excellent <a class="reference external" href="https://configobj.readthedocs.io/en/latest">ConfigObj</a> package.</p>
+<p>This all sounds a bit complicated but, believe me, it isn’t! To prove it
+(hopefully) lets look at an example. Say I have the following preferences in
+a file ‘example.ini’:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="p">[</span><span class="n">acme</span><span class="o">.</span><span class="n">ui</span><span class="p">]</span>
+<span class="n">bgcolor</span> <span class="o">=</span> <span class="n">blue</span>
+<span class="n">width</span> <span class="o">=</span> <span class="mi">50</span>
+<span class="n">ratio</span> <span class="o">=</span> <span class="mf">1.0</span>
+<span class="n">visible</span> <span class="o">=</span> <span class="kc">True</span>
+
+<span class="p">[</span><span class="n">acme</span><span class="o">.</span><span class="n">ui</span><span class="o">.</span><span class="n">splash_screen</span><span class="p">]</span>
+<span class="n">image</span> <span class="o">=</span> <span class="n">splash</span>
+<span class="n">fgcolor</span> <span class="o">=</span> <span class="n">red</span>
+</pre></div>
+</div>
+<p>I can create a preferences hierarchy from this file by:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="kn">from</span> <span class="nn">apptools.preferences.api</span> <span class="k">import</span> <span class="n">Preferences</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span> <span class="o">=</span> <span class="n">Preferences</span><span class="p">(</span><span class="n">filename</span><span class="o">=</span><span class="s1">&#39;example.ini&#39;</span><span class="p">)</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">dump</span><span class="p">()</span>
+
+<span class="go"> Node() {}</span>
+<span class="go">   Node(acme) {}</span>
+<span class="go">     Node(ui) {&#39;bgcolor&#39;: &#39;blue&#39;, &#39;width&#39;: &#39;50&#39;, &#39;ratio&#39;: &#39;1.0&#39;, &#39;visible&#39;: &#39;True&#39;}</span>
+<span class="go">       Node(splash_screen) {&#39;image&#39;: &#39;splash&#39;, &#39;fgcolor&#39;: &#39;red&#39;}</span>
+</pre></div>
+</div>
+<p>The ‘dump’ method (useful for debugging etc) simply ‘pretty prints’ a
+preferences hierarchy. The dictionary next to each node contains the node’s
+actual preferences. In this case, the root node (the node with no name) is the
+preferences object that we created. This node now has one child node ‘acme’,
+which contains no preferences. The ‘acme’ node has one child, ‘ui’, which
+contains some preferences (e.g. ‘bgcolor’) and also a child node
+‘splash_screen’ which also contains preferences (e.g. ‘image’).</p>
+<p>To look up a preference we use:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.bgcolor&#39;</span><span class="p">)</span>
+<span class="go">&#39;blue&#39;</span>
+</pre></div>
+</div>
+<p>If no such preferences exists then, by default, None is returned:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.bogus&#39;</span><span class="p">)</span> <span class="ow">is</span> <span class="kc">None</span>
+<span class="go">True</span>
+</pre></div>
+</div>
+<p>You can also specify an explicit default value:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.bogus&#39;</span><span class="p">,</span> <span class="s1">&#39;fred&#39;</span><span class="p">)</span>
+<span class="go">&#39;fred&#39;</span>
+</pre></div>
+</div>
+<p>To set a preference we use:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">set</span><span class="p">(</span><span class="s1">&#39;acme.ui.bgcolor&#39;</span><span class="p">,</span> <span class="s1">&#39;red&#39;</span><span class="p">)</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.bgcolor&#39;</span><span class="p">)</span>
+<span class="go">&#39;red&#39;</span>
+</pre></div>
+</div>
+<p>And to make sure the preferences are saved back to disk:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">flush</span><span class="p">()</span>
+</pre></div>
+</div>
+<p>To add a new preference value we simply set it:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">set</span><span class="p">(</span><span class="s1">&#39;acme.ui.fgcolor&#39;</span><span class="p">,</span> <span class="s1">&#39;black&#39;</span><span class="p">)</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.fgcolor&#39;</span><span class="p">)</span>
+<span class="go">&#39;black&#39;</span>
+</pre></div>
+</div>
+<p>Any missing nodes in a call to ‘set’ are created automatically, hence:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">set</span><span class="p">(</span><span class="s1">&#39;acme.ui.button.fgcolor&#39;</span><span class="p">,</span> <span class="s1">&#39;white&#39;</span><span class="p">)</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.button.fgcolor&#39;</span><span class="p">)</span>
+<span class="go">&#39;white&#39;</span>
+</pre></div>
+</div>
+<p>Preferences can also be ‘inherited’. e.g. Notice that the ‘splash_screen’
+node does not contain a ‘bgcolor’ preference, and hence:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.splash_screen.bgcolor&#39;</span><span class="p">)</span> <span class="ow">is</span> <span class="kc">None</span>
+<span class="go">True</span>
+</pre></div>
+</div>
+<p>But if we allow the ‘inheritance’ of preference values then:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.splash_screen.bgcolor&#39;</span><span class="p">,</span> <span class="n">inherit</span><span class="o">=</span><span class="kc">True</span><span class="p">)</span>
+<span class="go">&#39;red&#39;</span>
+</pre></div>
+</div>
+<p>By using ‘inheritance’ here the preferences system will try the following
+preferences:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="s1">&#39;acme.ui.splash_screen.bgcolor&#39;</span>
+<span class="s1">&#39;acme.ui.bgcolor&#39;</span>
+<span class="s1">&#39;acme.bgcolor&#39;</span>
+<span class="s1">&#39;bgcolor&#39;</span>
+</pre></div>
+</div>
+<div class="section" id="strings-glorious-strings">
+<h3>Strings, Glorious Strings<a class="headerlink" href="#strings-glorious-strings" title="Permalink to this headline">¶</a></h3>
+<p>At this point it is worth mentioning that preferences are <em>always</em> stored and
+returned as strings. This is because of the limitations of the traditional
+‘.ini’ file format i.e. they don’t contain any type information! Now before you
+start panicking, this doesn’t mean that all of your preferences have to be
+strings! Currently the preferences system allows, strings(!), booleans, ints,
+longs, floats and complex numbers. When you store a non-string value it gets
+converted to a string for you, but you <em>always</em> get a string back:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.width&#39;</span><span class="p">)</span>

+<span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.width&#39;</span><span class="p">)</span>
+<span class="go">&#39;100&#39;</span>
+
+<span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.visible&#39;</span><span class="p">)</span>

+<span class="go">&#39;False&#39;</span>
+</pre></div>
+</div>
+<p>This is obviously not terribly convenient, and so the following section
+discusses how we associate type information with our preferences to make
+getting and setting them more natural.</p>
+</div>
+</div>
+<div class="section" id="preferences-and-types">
+<h2>Preferences and Types<a class="headerlink" href="#preferences-and-types" title="Permalink to this headline">¶</a></h2>
+<p>As mentioned previously, we would like to be able to get and set non-string
+preferences in a more convenient way. This is where the <a class="reference internal" href="../api/apptools.preferences.preferences_helper.html#apptools.preferences.preferences_helper.PreferencesHelper" title="apptools.preferences.preferences_helper.PreferencesHelper"><code class="xref py py-class docutils literal notranslate"><span class="pre">PreferencesHelper</span></code></a>
+class comes in.</p>
+<p>Let’s take another look at ‘example.ini’:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="p">[</span><span class="n">acme</span><span class="o">.</span><span class="n">ui</span><span class="p">]</span>

+</pre></div>
+</div>
+<p>Say, I am interested in the preferences in the ‘acme.ui’ section. I can use a
+preferences helper as follows:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">apptools.preferences.api</span> <span class="k">import</span> <span class="n">PreferencesHelper</span>

+</pre></div>
+</div>
+<p>And, obviously, I can set the value of the preferences via the helper too:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">helper</span><span class="o">.</span><span class="n">ratio</span> <span class="o">=</span> <span class="mf">0.5</span>
+</pre></div>
+</div>
+<p>And if you want to prove to yourself it really did set the preference:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.ratio&#39;</span><span class="p">)</span>
+<span class="go">&#39;0.5&#39;</span>

+</div>
+<p>Using a preferences helper you also get notified via the usual trait
+mechanism when the preferences are changed (either via the helper or via the
+preferences node directly:</p>

+<h2>Scoped Preferences<a class="headerlink" href="#scoped-preferences" title="Permalink to this headline">¶</a></h2>
+<p>In many applications the idea of preferences scopes is useful. In a scoped
+system, an actual preference value can be stored in any scope and when a call
+is made to the ‘get’ method the scopes are searched in order of precedence.</p>
+<p>The default implementation (in the <a class="reference internal" href="../api/apptools.preferences.scoped_preferences.html#apptools.preferences.scoped_preferences.ScopedPreferences" title="apptools.preferences.scoped_preferences.ScopedPreferences"><code class="xref py py-class docutils literal notranslate"><span class="pre">ScopedPreferences</span></code></a> class) provides two
+scopes by default:</p>
+<ol class="arabic simple">
+<li><p>The application scope</p></li>
+</ol>
+<p>This scope stores itself in the ‘ETSConfig.application_home’ directory. This
+scope is generally used when <em>setting</em> any user preferences.</p>
+<ol class="arabic simple" start="2">
+<li><p>The default scope</p></li>
+</ol>
+<p>This scope is transient (i.e. it does not store itself anywhere). This scope
+is generally used to load any predefined default values into the preferences
+system.</p>
+<p>If you are happy with the default arrangement, then using the scoped
+preferences is just like using the plain old non-scoped version:</p>

+<p>Here you can see that the root node now has a child node representing each
+scope.</p>
+<p>When we are getting and setting preferences using scopes we generally want the
+following behaviour:</p>
+<p>a) When we get a preference we want to look it up in each scope in order. The
+first scope that contains a value ‘wins’.</p>
+<p>b) When we set a preference, we want to set it in the first scope. By default
+this means that when we set a preference it will be set in the application
+scope. This is exactly what we want as the application scope is the scope that
+is persistent.</p>
+<p>So usually, we just use the scoped preferences as before:</p>

+<p>This section discusses how an Envisage application uses the preferences
+mechanism. Envisage tries not to dictate too much, and so this describes the
+default behaviour, but you are free to override it as desired.</p>
+<p>Envisage uses the default implementation of the <a class="reference internal" href="../api/apptools.preferences.scoped_preferences.html#apptools.preferences.scoped_preferences.ScopedPreferences" title="apptools.preferences.scoped_preferences.ScopedPreferences"><code class="xref py py-class docutils literal notranslate"><span class="pre">ScopedPreferences</span></code></a> class which
+is made available via the application’s ‘preferences’ trait:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">application</span> <span class="o">=</span> <span class="n">Application</span><span class="p">(</span><span class="nb">id</span><span class="o">=</span><span class="s1">&#39;myapplication&#39;</span><span class="p">)</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">application</span><span class="o">.</span><span class="n">preferences</span><span class="o">.</span><span class="n">set</span><span class="p">(</span><span class="s1">&#39;acme.ui.bgcolor&#39;</span><span class="p">,</span> <span class="s1">&#39;yellow&#39;</span><span class="p">)</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">application</span><span class="o">.</span><span class="n">preferences</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s1">&#39;acme.ui.bgcolor&#39;</span><span class="p">)</span>
+<span class="go">&#39;yellow&#39;</span>
+</pre></div>
+</div>
+<p>Hence, you use the Envisage preferences just like you would any other scoped
+preferences.</p>
+<p>It also registers itself as the default preferences node used by the
+<a class="reference internal" href="../api/apptools.preferences.preferences_helper.html#apptools.preferences.preferences_helper.PreferencesHelper" title="apptools.preferences.preferences_helper.PreferencesHelper"><code class="xref py py-class docutils literal notranslate"><span class="pre">PreferencesHelper</span></code></a> class. Hence you don’t need to provide a preferences node
+explicitly to your helper:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">&gt;&gt;&gt; </span><span class="n">helper</span> <span class="o">=</span> <span class="n">SplashScreenPreferences</span><span class="p">()</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">helper</span><span class="o">.</span><span class="n">bgcolor</span>
+<span class="go">&#39;blue&#39;</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">helper</span><span class="o">.</span><span class="n">width</span>
+<span class="go">100</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">helper</span><span class="o">.</span><span class="n">ratio</span>
+<span class="go">1.0</span>
+<span class="gp">&gt;&gt;&gt; </span><span class="n">helper</span><span class="o">.</span><span class="n">visible</span>
+<span class="go">True</span>
+</pre></div>
+</div>
+<p>The only extra thing that Envisage does for you is to provide an extension
+point that allows you to contribute any number of ‘.ini’ files that are
+loaded into the default scope when the application is started.</p>
+<p>e.g. To contribute a preference file for my plugin I might use:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">MyPlugin</span><span class="p">(</span><span class="n">Plugin</span><span class="p">):</span>
+    <span class="o">...</span>
+
+    <span class="nd">@contributes_to</span><span class="p">(</span><span class="s1">&#39;envisage.preferences&#39;</span><span class="p">)</span>

+</ul>
+</div></blockquote>
+<p>This package is not just a toy framework and is powerful enough to
+provide full script recording to the <a class="reference external" href="https://docs.enthought.com/mayavi/mayavi/">Mayavi</a> application.  Mayavi is a

+<span id="scripting-api"></span><h2>The scripting API<a class="headerlink" href="#the-scripting-api" title="Permalink to this headline">¶</a></h2>
+<p>The scripting API primarily allows you to record UI actions for objects
+that have Traits.  Technically the framework listens to all trait
+changes so will work outside a UI.  We do not document the full API
+here, the best place to look for that is the
+<code class="docutils literal notranslate"><span class="pre">apptools.scripting.recorder</span></code> module which is reasonably well
+documented.  We provide a high level overview of the library.</p>
+<p>The quickest way to get started is to look at a small example.</p>

+</pre></div>
+</div>
+<p>Using these simple classes we first create a simple object hierarchy as
+follows:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">p</span> <span class="o">=</span> <span class="n">Parent</span><span class="p">()</span>
+<span class="n">c</span> <span class="o">=</span> <span class="n">Child</span><span class="p">()</span>
+<span class="n">t</span> <span class="o">=</span> <span class="n">Toy</span><span class="p">()</span>
+<span class="n">c</span><span class="o">.</span><span class="n">toy</span> <span class="o">=</span> <span class="n">t</span>
+<span class="n">p</span><span class="o">.</span><span class="n">children</span><span class="o">.</span><span class="n">append</span><span class="p">(</span><span class="n">c</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>Given this hierarchy, we’d like to be able to record a script.  To do
+this we setup the recording infrastructure:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">mayavi.core.recorder</span> <span class="k">import</span> <span class="n">Recorder</span><span class="p">,</span> <span class="n">set_recorder</span>
+<span class="c1"># Create a recorder.</span>
+<span class="n">r</span> <span class="o">=</span> <span class="n">Recorder</span><span class="p">()</span>
+<span class="c1"># Set the global recorder so the decorator works.</span>
+<span class="n">set_recorder</span><span class="p">(</span><span class="n">r</span><span class="p">)</span>
+<span class="n">r</span><span class="o">.</span><span class="n">register</span><span class="p">(</span><span class="n">p</span><span class="p">)</span>
+<span class="n">r</span><span class="o">.</span><span class="n">recording</span> <span class="o">=</span> <span class="kc">True</span>
+</pre></div>
+</div>
+<p>The key method here is the <code class="docutils literal notranslate"><span class="pre">r.register(p)</span></code> call above.  It looks at
+the traits of <code class="docutils literal notranslate"><span class="pre">p</span></code> and finds all traits and nested objects that specify
+a <code class="docutils literal notranslate"><span class="pre">record=True</span></code> in their trait metadata (all methods starting and
+ending with <code class="docutils literal notranslate"><span class="pre">_</span></code> are ignored).  All sub-objects are in turn registered
+with the recorder and so on.  Callbacks are attached to traits changes
+and these are wired up to produce readable and executable code.  The
+<code class="docutils literal notranslate"><span class="pre">set_recorder(r)</span></code> call is also very important and sets the global
+recorder so the framework listens to any functions that are decorated
+with the <code class="docutils literal notranslate"><span class="pre">recordable</span></code> decorator.</p>
+<p>Now lets test this out like so:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="c1"># The following will be recorded.</span>
+<span class="n">c</span><span class="o">.</span><span class="n">name</span> <span class="o">=</span> <span class="s1">&#39;Shiva&#39;</span>
+<span class="n">c</span><span class="o">.</span><span class="n">property</span><span class="o">.</span><span class="n">representation</span> <span class="o">=</span> <span class="s1">&#39;w&#39;</span>
+<span class="n">c</span><span class="o">.</span><span class="n">property</span><span class="o">.</span><span class="n">opacity</span> <span class="o">=</span> <span class="mf">0.4</span>
+<span class="n">c</span><span class="o">.</span><span class="n">grow</span><span class="p">(</span><span class="mi">1</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>To see what’s been recorded do this:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="nb">print</span><span class="p">(</span><span class="n">r</span><span class="o">.</span><span class="n">script</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>This prints:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">child</span> <span class="o">=</span> <span class="n">parent</span><span class="o">.</span><span class="n">children</span><span class="p">[</span><span class="mi">0</span><span class="p">]</span>
+<span class="n">child</span><span class="o">.</span><span class="n">name</span> <span class="o">=</span> <span class="s1">&#39;Shiva&#39;</span>
+<span class="n">child</span><span class="o">.</span><span class="n">property</span><span class="o">.</span><span class="n">representation</span> <span class="o">=</span> <span class="s1">&#39;wireframe&#39;</span>
+<span class="n">child</span><span class="o">.</span><span class="n">property</span><span class="o">.</span><span class="n">opacity</span> <span class="o">=</span> <span class="mf">0.40000000000000002</span>
+<span class="n">child</span><span class="o">.</span><span class="n">grow</span><span class="p">(</span><span class="mi">1</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>The recorder internally maintains a mapping between objects and unique
+names for each object.  It also stores the information about the
+location of a particular object in the object hierarchy.  For example,
+the path to the <code class="docutils literal notranslate"><span class="pre">Toy</span></code> instance in the hierarchy above is
+<code class="docutils literal notranslate"><span class="pre">parent.children[0].toy</span></code>.  Since scripting with lists this way can be
+tedious, the recorder first instantiates the <code class="docutils literal notranslate"><span class="pre">child</span></code>:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">child</span> <span class="o">=</span> <span class="n">parent</span><span class="o">.</span><span class="n">children</span><span class="p">[</span><span class="mi">0</span><span class="p">]</span>
+</pre></div>
+</div>
+<p>Subsequent lines use the <code class="docutils literal notranslate"><span class="pre">child</span></code> attribute.  The recorder always tries
+to instantiate the object referred to using its path information in this
+manner.</p>
+<p>To record a function or method call one must simply decorate the
+function/method with the <code class="docutils literal notranslate"><span class="pre">recordable</span></code> decorator.  Nested recordable
+functions are not recorded and trait changes are also not recorded if
+done inside a recordable function.</p>
+<div class="admonition note">
+<p class="admonition-title">Note</p>
+<ol class="arabic simple">
+<li><p>It is very important to note that the global recorder must be set
+via the <code class="docutils literal notranslate"><span class="pre">set_recorder</span></code> method.  The <code class="docutils literal notranslate"><span class="pre">recordable</span></code> decorator
+relies on this being set to work.</p></li>
+<li><p>The <code class="docutils literal notranslate"><span class="pre">recordable</span></code> decorator will work with plain Python classes
+and with functions too.</p></li>
+</ol>
+</div>
+<p>To stop recording do this:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">r</span><span class="o">.</span><span class="n">unregister</span><span class="p">(</span><span class="n">p</span><span class="p">)</span>

+</div>
+<p>The <code class="docutils literal notranslate"><span class="pre">r.unregister(p)</span></code> reverses the <code class="docutils literal notranslate"><span class="pre">r.register(p)</span></code> call and

+<div class="section" id="advanced-use-cases">
+<span id="recorder-advanced-uses"></span><h3>Advanced use cases<a class="headerlink" href="#advanced-use-cases" title="Permalink to this headline">¶</a></h3>
+<p>Here are a few advanced use cases.</p>
+<blockquote>
+<div><ul class="simple">
+<li><p>The API also provides a <code class="docutils literal notranslate"><span class="pre">RecorderWithUI</span></code> class that provides a
+simple user interface that prints the recorded script and allows the
+user to save the script.</p></li>
+<li><p>Sometimes it is not enough to just record trait changes, one may want
+to pass an arbitrary string or command when recording is occurring.
+To allow for this, if one defines a <code class="docutils literal notranslate"><span class="pre">recorder</span></code> trait on the object,
+it is set to the current recorder.  One can then use this recorder to
+do whatever one wants.  This is very convenient.</p></li>
+<li><p>To ignore specific traits one must specify either a <code class="docutils literal notranslate"><span class="pre">record=False</span></code>
+metadata to the trait definition or specify a list of strings to the
+<code class="docutils literal notranslate"><span class="pre">register</span></code> method in the <code class="docutils literal notranslate"><span class="pre">ignore</span></code> keyword argument.</p></li>
+<li><p>If you want to use a specific name for an object on the script you
+can pass the <code class="docutils literal notranslate"><span class="pre">script_id</span></code> parameter to the register function.</p></li>
+</ul>
+</div></blockquote>
+<p>For more details on the recorder itself we suggest reading the module
+source code.  It is fairly well documented and with the above background
+should be enough to get you going.</p>

+<p>It is quite common in GUI applications to have a UI element displaying a
+collection of items that a user can select (“selection providers”), while
+other parts of the application must react to changes in the selection
+(“selection listeners”).</p>
+<p>Ideally, the listeners would not have a direct dependency on the UI object.
+This is especially important in extensible <a class="reference external" href="http://docs.enthought.com/envisage/">envisage</a> applications, where
+a plugin might need to react to a selection change, but we do not want to
+expose the internal organization of the application to external developers.</p>
+<p>This package defines a selection service that manages the communication
+between providers and listener.</p>

+the communication between selection providers and listener.</p>
+<p><a class="reference internal" href="#selection-providers"><span class="std std-ref">Selection providers</span></a> are components that wish to
+publish information about their current selection for public consumption.
+They register to a selection

+<p><a class="reference internal" href="#selection-listeners"><span class="std std-ref">Selection listeners</span></a> can query the selection

+interface, and registering to the selection service.</p>
+<p>Selection providers must provide a unique ID
+<a class="reference internal" href="../api/apptools.selection.i_selection_provider.html#apptools.selection.i_selection_provider.ISelectionProvider.provider_id" title="apptools.selection.i_selection_provider.ISelectionProvider.provider_id"><code class="xref py py-attr docutils literal notranslate"><span class="pre">provider_id</span></code></a>,
+which is used by listeners to request its current selection.</p>
+<p>Whenever its selection changes, providers fire a
+<a class="reference internal" href="../api/apptools.selection.i_selection_provider.html#apptools.selection.i_selection_provider.ISelectionProvider.selection" title="apptools.selection.i_selection_provider.ISelectionProvider.selection"><code class="xref py py-attr docutils literal notranslate"><span class="pre">selection</span></code></a>
+event. The content of the event is an instance implementing

+For example, a <a class="reference internal" href="../api/apptools.selection.list_selection.html#apptools.selection.list_selection.ListSelection" title="apptools.selection.list_selection.ListSelection"><code class="xref py py-class docutils literal notranslate"><span class="pre">ListSelection</span></code></a> object contains a list of selected
+items, and their indices.</p>
+<p>Selection providers can also be queried directly about their current selection
+using the

+<div class="section" id="registration">

+<p>Typically, selection providers are UI objects showing a list or tree of items,
+they register as soon as the UI component is initialized, and un-register
+when the UI component disappears (e.g., because their window has been closed).
+In more complex applications, the registration could be done by a controller
+object instead.</p>

+<div class="section" id="selection-listeners">
+<span id="id2"></span><h2>Selection listeners<a class="headerlink" href="#selection-listeners" title="Permalink to this headline">¶</a></h2>
+<p>Selection listeners request information regarding the current selection

+method. They need to provide the unique ID of the provider, and a function
+(or callable) that is called to send the event. This callback function takes

+the selection.</p>
+<p>It is possible for a listener to connect to a provider ID before it is
+registered. As soon as the provider is registered, the listener will receive
+a notification containing the provider’s initial selection.</p>

+<h3>Active querying<a class="headerlink" href="#active-querying" title="Permalink to this headline">¶</a></h3>
+<p>In other instances, an element of the application only needs the current

+representing a user action based on what is currently selected in the active
+editor.</p>
+<p>The

+<h1>Undo Framework<a class="headerlink" href="#undo-framework" title="Permalink to this headline">¶</a></h1>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>apptools.undo has been deprecated and moved to
+<a class="reference external" href="https://github.com/enthought/pyface">Pyface</a>. It will be removed in a
+future release. Please use <a class="reference external" href="https://docs.enthought.com/pyface/undo.html">pyface.undo</a>
+instead.</p>
+</div>
+<p>The Undo Framework is a component of the Enthought Tool Suite that provides
+developers with an API that implements the standard pattern for do/undo/redo
+commands.</p>
+<p>The framework is completely configurable.  Alternate implementations of all
+major components can be provided if necessary.</p>
+<div class="section" id="framework-concepts">
+<h2>Framework Concepts<a class="headerlink" href="#framework-concepts" title="Permalink to this headline">¶</a></h2>
+<p>The following are the concepts supported by the framework.</p>
+<ul>
+<li><p>Command</p>
+<p>A command is an application defined operation that can be done (i.e.
+executed), undone (i.e. reverted) and redone (i.e. repeated).</p>
+<p>A command operates on some data and maintains sufficient state to allow it to
+revert or repeat a change to the data.</p>
+<p>Commands may be merged so that potentially long sequences of similar
+commands (e.g. to add a character to some text) can be collapsed into a
+single command (e.g. to add a word to some text).</p>
+</li>
+<li><p>Macro</p>
+<p>A macro is a sequence of commands that is treated as a single command when
+being undone or redone.</p>
+</li>
+<li><p>Command Stack</p>
+<p>A command is done by pushing it onto a command stack.  The last command can
+be undone and redone by calling appropriate command stack methods.  It is
+also possible to move the stack’s position to any point and the command stack
+will ensure that commands are undone or redone as required.</p>
+<p>A command stack maintains a <em>clean</em> state which is updated as commands are
+done and undone.  It may be explicitly set, for example when the data being
+manipulated by the commands is saved to disk.</p>
+<p>Canned PyFace actions are provided as wrappers around command stack methods
+to implement common menu items.</p>
+</li>
+<li><p>Undo Manager</p>
+<p>An undo manager is responsible for one or more command stacks and maintains
+a reference to the currently active stack.  It provides convenience undo and
+redo methods that operate on the currently active stack.</p>
+<p>An undo manager ensures that each command execution is allocated a unique
+sequence number, irrespective of which command stack it is pushed to.  Using
+this it is possible to synchronise multiple command stacks and restore them
+to a particular point in time.</p>
+<p>An undo manager will generate an event whenever the clean state of the active
+stack changes.  This can be used to maintain some sort of GUI status
+indicator to tell the user that their data has been modified since it was
+last saved.</p>
+</li>
+</ul>
+<p>Typically an application will have one undo manager and one undo stack for
+each data type that can be edited.  However this is not a requirement: how the
+command stack’s in particular are organised and linked (with the user
+manager’s sequence number) can need careful thought so as not to confuse the
+user - particularly in a plugin based application that may have many editors.</p>
+<p>To support this typical usage the PyFace <code class="docutils literal notranslate"><span class="pre">Workbench</span></code> class has an
+<code class="docutils literal notranslate"><span class="pre">undo_manager</span></code> trait and the PyFace <code class="docutils literal notranslate"><span class="pre">Editor</span></code> class has a <code class="docutils literal notranslate"><span class="pre">command_stack</span></code>
+trait.  Both are lazy loaded so can be completely ignored if they are not used.</p>

+<div class="section" id="api-overview">
+<h2>API Overview<a class="headerlink" href="#api-overview" title="Permalink to this headline">¶</a></h2>
+<p>This section gives a brief overview of the various classes implemented in the
+framework.  The complete <a class="reference external" href="api/index.html">API</a> documentation is available as endo generated
+HTML.</p>

 Undo Framework
 ==============
 
+.. warning:: 
+    apptools.undo has been deprecated and moved to
+    `Pyface <https://github.com/enthought/pyface>`_. It will be removed in a
+    future release. Please use `pyface.undo <https://docs.enthought.com/pyface/undo.html>`_
+    instead.
+
 The Undo Framework is a component of the Enthought Tool Suite that provides
 developers with an API that implements the standard pattern for do/undo/redo
 commands.

-<dd><p>Returns the width to use for a specified column.</p>
-<p>If the value is &lt;= 0, the column will have a <em>default</em> width, which is
-the same as specifying a width of 0.1.</p>
-<p>If the value is &gt; 1.0, it is converted to an integer and the result is
-the width of the column in pixels. This is referred to as a
-<em>fixed width</em> column.</p>
-<p>If the value is a float such that 0.0 &lt; value &lt;= 1.0, it is treated as
-the <em>unnormalized fraction of the available space</em> that is to be
-assigned to the column. What this means requires a little explanation.</p>
-<p>To arrive at the size in pixels of the column at any given time, the
-editor adds together all of the <em>unnormalized fraction</em> values
-returned for all columns in the table to arrive at a total value. Each
-<em>unnormalized fraction</em> is then divided by the total to create a
-<em>normalized fraction</em>. Each column is then assigned an amount of space
-in pixels equal to the maximum of 30 or its <em>normalized fraction</em>
-multiplied by the <em>available space</em>. The <em>available space</em> is defined
-as the actual width of the table minus the width of all <em>fixed width</em>
-columns. Note that this calculation is performed each time the table is
-resized in the user interface, thus allowing columns of this type to
-increase or decrease their width dynamically, while leaving <em>fixed
-width</em> columns unchanged.</p>

+<p>If the value is &lt;= 0, the column will have a <em>default</em> width, which is
+the same as specifying a width of 0.1.</p>
+<p>If the value is &gt; 1.0, it is converted to an integer and the result is
+the width of the column in pixels. This is referred to as a
+<em>fixed width</em> column.</p>
+<p>If the value is a float such that 0.0 &lt; value &lt;= 1.0, it is treated as
+the <em>unnormalized fraction of the available space</em> that is to be
+assigned to the column. What this means requires a little explanation.</p>
+<p>To arrive at the size in pixels of the column at any given time, the
+editor adds together all of the <em>unnormalized fraction</em> values
+returned for all columns in the table to arrive at a total value. Each
+<em>unnormalized fraction</em> is then divided by the total to create a
+<em>normalized fraction</em>. Each column is then assigned an amount of space
+in pixels equal to the maximum of 30 or its <em>normalized fraction</em>
+multiplied by the <em>available space</em>. The <em>available space</em> is defined
+as the actual width of the table minus the width of all <em>fixed width</em>
+columns. Note that this calculation is performed each time the table is
+resized in the user interface, thus allowing columns of this type to
+increase or decrease their width dynamically, while leaving <em>fixed
+width</em> columns unchanged.</p>

+<p>Provider of a framework that dynamically determines the contents of a
+context at the time of interaction with the contents rather than at the
+time a class is written.</p>
+<p>This capability is particularly useful when the object acting as a context
+is part of a plug-in application – such as Envisage.  In general, this
+capability allows the context to be:</p>
+<ul class="simple">
+<li><p>Extendable by contributions from somewhere other than the original
+code writer</p></li>
+<li><p>Dynamic in that the elements it is composed of can change each time
+someone interacts with the contents of the context.</p></li>
+</ul>
+<p>It should be noted that this capability is explicitly different from
+contexts that look at another container to determine their contents, such
+as a file system context!</p>
+<p>Users of this framework contribute items to a dynamic context by adding
+traits to the dynamic context instance.  (This addition can happen
+statically through the use of a Traits Category.)  The trait value is the
+context item’s value and the trait definition’s metadata determines how the
+item is treated within the context.  The support metadata is:</p>
+<dl class="simple">
+<dt>context_name: A non-empty string</dt><dd><p>Represents the name of the item within this context.  This must be
+present for the trait to show up as a context item though the value
+may change over time as the item gets bound to different names.</p>
+</dd>
+<dt>context_order: A float value</dt><dd><p>Indicates the position for the item within this context.  All
+dynamically contributed context items are sorted by ascending order
+of this value using the standard list sort function.</p>
+</dd>
+<dt>is_context: A boolean value</dt><dd><p>True if the item is itself a context.</p>

+<p>A reference to an object that lives outside of the naming system.</p>
+<p>References provide a way to store the address(s) of objects that live
+outside of the naming system.  A reference consists of a list of
+addresses that represent a communications endpoint for the object being
+referenced.</p>
+<p>A reference also contains information to assist in the creation of an
+instance of the object to which it refers.  It contains the name of
+the class that will be created and the class name and location of a
+factory that will be used to do the actual instance creation.</p>

-<p>This module provides code that allows one to pickle the state of a
-Python object to a dictionary.</p>
-<p>The motivation for this is simple.  The standard Python
-pickler/unpickler is best used to pickle simple objects and does not
-work too well for complex code.  Specifically, there are two major
-problems (1) the pickle file format is not easy to edit with a text
-editor and (2) when a pickle is unpickled, it creates all the
-necessary objects and sets the state of these objects.</p>
-<p>Issue (2) might not appear to be a problem.  However, often, the
-determination of the entire ‘state’ of an application requires the
-knowledge of the state of many objects that are not really in the
-users concern.  The user would ideally like to pickle just what he
-thinks is relevant.  Now, given that the user is not going to save the
-entire state of the application, the use of pickle is insufficient
-since the state is no longer completely known (or worth knowing).  The
-default <cite>Unpickler</cite> recreates the objects and the typical
-implementation of <cite>__setstate__</cite> is usually to simply update the
-object’s <cite>__dict__</cite> attribute.  This is inadequate because the pickled
-information is taken out of the real context when it was saved.</p>
-<p>The <cite>StatePickler</cite> basically pickles the ‘state’ of an object into a
-large dictionary.  This pickled data may be easily unpickled and
-modified on the interpreter or edited with a text editor
-(<cite>pprint.saferepr</cite> is a friend).  The second problem is also
-eliminated.  When this state is unpickled using <cite>StateUnpickler</cite>, what
-you get is a special dictionary (a <cite>State</cite> instance).  This allows one
-to navigate the state just like the original object.  Its up to the
-user to create any new objects and set their states using this
-information.  This allows for a lot of flexibility while allowing one
-to save and set the state of (almost) any Python object.</p>
-<p>The <cite>StateSetter</cite> class helps set the state of a known instance.  When
-setting the state of an instance it checks to see if there is a
-<cite>__set_pure_state__</cite> method that in turn calls <cite>StateSetter.set</cite>
-appropriately.</p>
-<p>Additionally, there is support for versioning.  The class’ version is
-obtain from the <cite>__version__</cite> class attribute.  This version along
-with the versions of the bases of a class is embedded into the
-metadata of the state and stored.  By using <cite>version_registry.py</cite> a
-user may register a handler for a particular class and module.  When
-the state of an object is set using <cite>StateSetter.set_state</cite>, then
-these handlers are called in reverse order of their MRO.  This gives
-the handler an opportunity to upgrade the state depending on its
-version.  Builtin classes are not scanned for versions.  If a class
-has no version, then by default it is assumed to be -1.</p>

+<p>This module provides code that allows one to pickle the state of a
+Python object to a dictionary.</p>
+<p>The motivation for this is simple.  The standard Python
+pickler/unpickler is best used to pickle simple objects and does not
+work too well for complex code.  Specifically, there are two major
+problems (1) the pickle file format is not easy to edit with a text
+editor and (2) when a pickle is unpickled, it creates all the
+necessary objects and sets the state of these objects.</p>
+<p>Issue (2) might not appear to be a problem.  However, often, the
+determination of the entire ‘state’ of an application requires the
+knowledge of the state of many objects that are not really in the
+users concern.  The user would ideally like to pickle just what he
+thinks is relevant.  Now, given that the user is not going to save the
+entire state of the application, the use of pickle is insufficient
+since the state is no longer completely known (or worth knowing).  The
+default <cite>Unpickler</cite> recreates the objects and the typical
+implementation of <cite>__setstate__</cite> is usually to simply update the
+object’s <cite>__dict__</cite> attribute.  This is inadequate because the pickled
+information is taken out of the real context when it was saved.</p>
+<p>The <cite>StatePickler</cite> basically pickles the ‘state’ of an object into a
+large dictionary.  This pickled data may be easily unpickled and
+modified on the interpreter or edited with a text editor
+(<cite>pprint.saferepr</cite> is a friend).  The second problem is also
+eliminated.  When this state is unpickled using <cite>StateUnpickler</cite>, what
+you get is a special dictionary (a <cite>State</cite> instance).  This allows one
+to navigate the state just like the original object.  Its up to the
+user to create any new objects and set their states using this
+information.  This allows for a lot of flexibility while allowing one
+to save and set the state of (almost) any Python object.</p>
+<p>The <cite>StateSetter</cite> class helps set the state of a known instance.  When
+setting the state of an instance it checks to see if there is a
+<cite>__set_pure_state__</cite> method that in turn calls <cite>StateSetter.set</cite>
+appropriately.</p>
+<p>Additionally, there is support for versioning.  The class’ version is
+obtain from the <cite>__version__</cite> class attribute.  This version along
+with the versions of the bases of a class is embedded into the
+metadata of the state and stored.  By using <cite>version_registry.py</cite> a
+user may register a handler for a particular class and module.  When
+the state of an object is set using <cite>StateSetter.set_state</cite>, then
+these handlers are called in reverse order of their MRO.  This gives
+the handler an opportunity to upgrade the state depending on its
+version.  Builtin classes are not scanned for versions.  If a class
+has no version, then by default it is assumed to be -1.</p>

-<p>There is one drawback to this scheme. If you want to access a scope node
-itself via the ‘clear’, ‘keys’, ‘node’, ‘node_exists’ or ‘node_names’
-methods then you have to append a trailing ‘/’ to the path. Without that,
-the node would try to perform the operation in the primary scope.</p>
-<p>e.g. To get the names of the children of the ‘application’ scope, use:</p>
-<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">scoped</span><span class="o">.</span><span class="n">node_names</span><span class="p">(</span><span class="s1">&#39;application/&#39;</span><span class="p">)</span>
-</pre></div>
-</div>
-<p>If you did this:</p>
-<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">scoped</span><span class="o">.</span><span class="n">node_names</span><span class="p">(</span><span class="s1">&#39;application&#39;</span><span class="p">)</span>
-</pre></div>
-</div>
-<p>Then the node would get the primary scope and try to find its child node
-called ‘application’.</p>
-<p>Of course you can just get the scope via:</p>
-<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">application_scope</span> <span class="o">=</span> <span class="n">scoped</span><span class="o">.</span><span class="n">get_scope</span><span class="p">(</span><span class="s1">&#39;application&#39;</span><span class="p">)</span>
-</pre></div>
-</div>
-<p>and then call whatever methods you like on it - which is definitely more
-intentional and is highly recommended:</p>
-<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">application_scope</span><span class="o">.</span><span class="n">node_names</span><span class="p">()</span>

+<p>A preferences node that adds the notion of preferences scopes.</p>
+<p>Scopes provide a way to access preferences in a precedence order, usually

+or set by the user in a preferences file, or the defaults (set by the
+developer).</p>
+<p>By default, this class provides two scopes - ‘application’ which is
+persistent and ‘default’ which is not.</p>

+<p>There is one drawback to this scheme. If you want to access a scope node
+itself via the ‘clear’, ‘keys’, ‘node’, ‘node_exists’ or ‘node_names’
+methods then you have to append a trailing ‘/’ to the path. Without that,
+the node would try to perform the operation in the primary scope.</p>
+<p>e.g. To get the names of the children of the ‘application’ scope, use:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">scoped</span><span class="o">.</span><span class="n">node_names</span><span class="p">(</span><span class="s1">&#39;application/&#39;</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>If you did this:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">scoped</span><span class="o">.</span><span class="n">node_names</span><span class="p">(</span><span class="s1">&#39;application&#39;</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>Then the node would get the primary scope and try to find its child node
+called ‘application’.</p>
+<p>Of course you can just get the scope via:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">application_scope</span> <span class="o">=</span> <span class="n">scoped</span><span class="o">.</span><span class="n">get_scope</span><span class="p">(</span><span class="s1">&#39;application&#39;</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>and then call whatever methods you like on it - which is definitely more
+intentional and is highly recommended:</p>
+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">application_scope</span><span class="o">.</span><span class="n">node_names</span><span class="p">()</span>
