Subclass of InteractiveShell for terminal based frontends.
Bases: IPython.core.magic.Magics
Toggle autoindent on/off (if available).
Paste & execute a pre-formatted code block from clipboard.
You must terminate the block with ‘–’ (two minus-signs) or Ctrl-D alone on the line. You can also provide your own sentinel with ‘%paste -s %%’ (‘%%’ is the new sentinel for this operation)
The block is dedented prior to execution to enable execution of method definitions. ‘>’ and ‘+’ characters at the beginning of a line are ignored, to allow pasting directly from e-mails, diff files and doctests (the ‘...’ continuation prompt is also stripped). The executed block is also assigned to variable named ‘pasted_block’ for later editing with ‘%edit pasted_block’.
You can also pass a variable name as an argument, e.g. ‘%cpaste foo’. This assigns the pasted block to variable ‘foo’ as string, without dedenting or executing it (preceding >>> and + is still stripped)
‘%cpaste -r’ re-executes the block previously entered by cpaste.
Do not be alarmed by garbled output on Windows (it’s a readline bug). Just press enter and type – (and press enter again) and the block will be what was just pasted.
IPython statements (magics, shell escapes) are not supported (yet).

Examples
In [8]: %cpaste
Pasting code; enter '--' alone on the line to stop.
:>>> a = ["world!", "Hello"]
:>>> print " ".join(sorted(a))
:--
Hello world!
Paste & execute a pre-formatted code block from clipboard.
The text is pulled directly from the clipboard without user intervention and printed back on the screen before execution (unless the -q flag is given to force quiet mode).
The block is dedented prior to execution to enable execution of method definitions. ‘>’ and ‘+’ characters at the beginning of a line are ignored, to allow pasting directly from e-mails, diff files and doctests (the ‘...’ continuation prompt is also stripped).

You can also pass a variable name as an argument, e.g. ‘%paste foo’. This assigns the pasted block to variable ‘foo’ as string, without executing it (preceding >>> and + is still stripped).

Switch amongst GUI input hooks by name.
Handle interactive exit.
This method calls the ask_exit callback.
Closely emulate the interactive Python console.
Start the mainloop.
If an optional banner argument is given, it will override the internally created default banner.
A trait for unicode strings.
Write a prompt and read a line.
The returned line does not include the trailing newline. When the user enters the EOF key sequence, EOFError is raised.
Optional inputs:
- prompt(‘’): a string to be printed to prompt the user.
- continue_prompt(False): whether this line is the first one or a
continuation in a sequence of inputs.
An integer trait.
Longs that are unnecessary (<= sys.maxint) are cast to ints.
