+"""Module for interactive demos using IPython.
+
+This module implements a few classes for running Python scripts interactively
+in IPython for demonstrations.  With very simple markup (a few tags in
+comments), you can control points where the script stops executing and returns
+control to IPython.
+
+
+Provided classes
+----------------
+
+The classes are (see their docstrings for further details):
+
+ - Demo: pure python demos
+
+ - IPythonDemo: demos with input to be processed by IPython as if it had been
+   typed interactively (so magics work, as well as any other special syntax you
+   may have added via input prefilters).
+
+ - LineDemo: single-line version of the Demo class.  These demos are executed
+   one line at a time, and require no markup.
+
+ - IPythonLineDemo: IPython version of the LineDemo class (the demo is
+   executed a line at a time, but processed via IPython).
+
+ - ClearMixin: mixin to make Demo classes with less visual clutter.  It
+   declares an empty marquee and a pre_cmd that clears the screen before each
+   block (see Subclassing below).
+
+ - ClearDemo, ClearIPDemo: mixin-enabled versions of the Demo and IPythonDemo
+   classes.
+
+Inheritance diagram:
+
+.. inheritance-diagram:: IPython.lib.demo
+   :parts: 3
+
+Subclassing
+-----------
+
+The classes here all include a few methods meant to make customization by
+subclassing more convenient.  Their docstrings below have some more details:
+
+  - highlight(): format every block and optionally highlight comments and
+    docstring content.
+
+  - marquee(): generates a marquee to provide visible on-screen markers at each
+    block start and end.
+
+  - pre_cmd(): run right before the execution of each block.
+
+  - post_cmd(): run right after the execution of each block.  If the block
+    raises an exception, this is NOT called.
+
+
+Operation
+---------
+
+The file is run in its own empty namespace (though you can pass it a string of
+arguments as if in a command line environment, and it will see those as
+sys.argv).  But at each stop, the global IPython namespace is updated with the
+current internal demo namespace, so you can work interactively with the data
+accumulated so far.
+
+By default, each block of code is printed (with syntax highlighting) before
+executing it and you have to confirm execution.  This is intended to show the
+code to an audience first so you can discuss it, and only proceed with
+execution once you agree.  There are a few tags which allow you to modify this
+behavior.
+
+The supported tags are:
+
+# <demo> stop
+
+  Defines block boundaries, the points where IPython stops execution of the
+  file and returns to the interactive prompt.
+
+  You can optionally mark the stop tag with extra dashes before and after the
+  word 'stop', to help visually distinguish the blocks in a text editor:
+
+  # <demo> --- stop ---
+
+
+# <demo> silent
+
+  Make a block execute silently (and hence automatically).  Typically used in
+  cases where you have some boilerplate or initialization code which you need
+  executed but do not want to be seen in the demo.
+
+# <demo> auto
+
+  Make a block execute automatically, but still being printed.  Useful for
+  simple code which does not warrant discussion, since it avoids the extra
+  manual confirmation.
+
+# <demo> auto_all
+
+  This tag can _only_ be in the first block, and if given it overrides the
+  individual auto tags to make the whole demo fully automatic (no block asks
+  for confirmation).  It can also be given at creation time (or the attribute
+  set later) to override what's in the file.
+
+While _any_ python file can be run as a Demo instance, if there are no stop
+tags the whole file will run in a single block (no different that calling
+first %pycat and then %run).  The minimal markup to make this useful is to
+place a set of stop tags; the other tags are only there to let you fine-tune
+the execution.
+
+This is probably best explained with the simple example file below.  You can
+copy this into a file named ex_demo.py, and try running it via::
+
+    from IPython.lib.demo import Demo
+    d = Demo('ex_demo.py')
+    d()
+
+Each time you call the demo object, it runs the next block.  The demo object
+has a few useful methods for navigation, like again(), edit(), jump(), seek()
+and back().  It can be reset for a new run via reset() or reloaded from disk
+(in case you've edited the source) via reload().  See their docstrings below.
+
+Note: To make this simpler to explore, a file called "demo-exercizer.py" has
+been added to the "docs/examples/core" directory.  Just cd to this directory in
+an IPython session, and type::
+
+  %run demo-exercizer.py
+
+and then follow the directions.
+
+Example
+-------
+
+The following is a very simple example of a valid demo file.
+
+::
+
+    #################### EXAMPLE DEMO <ex_demo.py> ###############################
+    '''A simple interactive demo to illustrate the use of IPython's Demo class.'''
+
+    print('Hello, welcome to an interactive IPython demo.')
+
+    # The mark below defines a block boundary, which is a point where IPython will
+    # stop execution and return to the interactive prompt. The dashes are actually
+    # optional and used only as a visual aid to clearly separate blocks while
+    # editing the demo code.
+    # <demo> stop
+
+    x = 1
+    y = 2
+
+    # <demo> stop
+
+    # the mark below makes this block as silent
+    # <demo> silent
+
+    print('This is a silent block, which gets executed but not printed.')
+
+    # <demo> stop
+    # <demo> auto
+    print('This is an automatic block.')
+    print('It is executed without asking for confirmation, but printed.')
+    z = x + y
+
+    print('z =', x)
+
+    # <demo> stop
+    # This is just another normal block.
+    print('z is now:', z)
+
+    print('bye!')

+
+    Parameters
+    ----------
+    data : numpy array, list, unicode, str or bytes
+        Can be one of
+
+          * Numpy 1d array containing the desired waveform (mono)
+          * Numpy 2d array containing waveforms for each channel.
+            Shape=(NCHAN, NSAMPLES). For the standard channel order, see
+            http://msdn.microsoft.com/en-us/library/windows/hardware/dn653308(v=vs.85).aspx
+          * List of float or integer representing the waveform (mono)
+          * String containing the filename
+          * Bytestring containing raw PCM data or
+          * URL pointing to a file on the web.
+
+        If the array option is used, the waveform will be normalized.
+
+        If a filename or url is used, the format support will be browser
+        dependent.
+    url : unicode
+        A URL to download the data from.
+    filename : unicode
+        Path to a local file to load the data from.
+    embed : boolean
+        Should the audio data be embedded using a data URI (True) or should
+        the original source be referenced. Set this to True if you want the
+        audio to playable later with no internet connection in the notebook.
+
+        Default is `True`, unless the keyword argument `url` is set, then
+        default value is `False`.
+    rate : integer
+        The sampling rate of the raw data.
+        Only required when data parameter is being used as an array
+    autoplay : bool
+        Set to True if the audio should immediately start playing.
+        Default is `False`.
+    normalize : bool
+        Whether audio should be normalized (rescaled) to the maximum possible
+        range. Default is `True`. When set to `False`, `data` must be between
+        -1 and 1 (inclusive), otherwise an error is raised.
+        Applies only when `data` is a list or array of samples; other types of
+        audio are never normalized.

+Python advanced pretty printer.  This pretty printer is intended to
+replace the old `pprint` python module which does not allow developers
+to provide their own pretty print callbacks.
+
+This module is based on ruby's `prettyprint.rb` library by `Tanaka Akira`.
+
+
+Example Usage
+-------------
+
+To directly print the representation of an object use `pprint`::
+
+    from pretty import pprint
+    pprint(complex_object)
+
+To get a string of the output use `pretty`::
+
+    from pretty import pretty
+    string = pretty(complex_object)
+
+
+Extending
+---------
+
+The pretty library allows developers to add pretty printing rules for their
+own objects.  This process is straightforward.  All you have to do is to
+add a `_repr_pretty_` method to your object and call the methods on the
+pretty printer passed::
+
+    class MyObject(object):
+
+        def _repr_pretty_(self, p, cycle):
+            ...
+
+Here's an example for a class with a simple constructor::
+
+    class MySimpleObject:
+
+        def __init__(self, a, b, *, c=None):
+            self.a = a
+            self.b = b
+            self.c = c
+
+        def _repr_pretty_(self, p, cycle):
+            ctor = CallExpression.factory(self.__class__.__name__)
+            if self.c is None:
+                p.pretty(ctor(a, b))
+            else:
+                p.pretty(ctor(a, b, c=c))
+
+Here is an example implementation of a `_repr_pretty_` method for a list
+subclass::
+
+    class MyList(list):
+
+        def _repr_pretty_(self, p, cycle):
+            if cycle:
+                p.text('MyList(...)')
+            else:
+                with p.group(8, 'MyList([', '])'):
+                    for idx, item in enumerate(self):
+                        if idx:
+                            p.text(',')
+                            p.breakable()
+                        p.pretty(item)
+
+The `cycle` parameter is `True` if pretty detected a cycle.  You *have* to
+react to that or the result is an infinite loop.  `p.text()` just adds
+non breaking text to the output, `p.breakable()` either adds a whitespace
+or breaks here.  If you pass it an argument it's used instead of the
+default space.  `p.pretty` prettyprints another object using the pretty print
+method.
+
+The first parameter to the `group` function specifies the extra indentation
+of the next line.  In this example the next item will either be on the same
+line (if the items are short enough) or aligned with the right edge of the
+opening bracket of `MyList`.
+
+If you just want to indent something you can use the group function
+without open / close parameters.  You can also use this code::
+
+    with p.indent(2):
+        ...

+        The filters have to be composed of pre-defined verbs and joined by one
+        of the following conjunctions: ``&`` (and), ``|`` (or), ``~`` (not).

+=======================================================
+ Nose plugin with IPython and extension module support
+=======================================================
+
+This directory provides the key functionality for test support that IPython
+needs as a nose plugin, which can be installed for use in projects other than
+IPython.
+
+The presence of a Makefile here is mostly for development and debugging
+purposes as it only provides a few shorthand commands.  You can manually
+install the plugin by using standard Python procedures (``setup.py install``
+with appropriate arguments).
+
+To install the plugin using the Makefile, edit its first line to reflect where
+you'd like the installation.
+
+Once you've set the prefix, simply build/install the plugin with::
+
+  make
+
+and run the tests with::
+
+  make test
+
+You should see output similar to::
+
+  maqroll[plugin]> make test
+  nosetests -s --with-ipdoctest --doctest-tests dtexample.py
+  ..
+  ----------------------------------------------------------------------

+- When generating examples for use as doctests, make sure that you have

+  by interactively disabling it with  %Pprint.  This is required so that IPython
+  output matches that of normal Python, which is used by doctest for internal

+
+- Do not rely on specific prompt numbers for results (such as using
+  '_34==True', for example).  For IPython tests run via an external process the
+  prompt numbers may be different, and IPython tests run as normal python code
+  won't even have these special _NN variables set at all.
