Any transformation to a string goes through here. In other words, the SagePlainTextFormatter is entirely implemented via SagePrettyPrinter. Other formatters may or may not use SagePrettyPrinter to generate text output.

Pretty print Sage objects for the commandline
INPUT:
See IPython documentation.
EXAMPLES:
sage: 123
123
IPython pretty printers:
sage: set({1, 2, 3})
{1, 2, 3}
sage: dict(zzz=123, aaa=99, xab=10) # sorted by keys
{'aaa': 99, 'xab': 10, 'zzz': 123}
These are overridden in IPython in a way that we feel is somewhat confusing, and we prefer to print them like plain Python which is more informative. See trac ticket #14466
sage: 'this is a string'
'this is a string'
sage: type(123)
<type 'sage.rings.integer.Integer'>
sage: type
<type 'type'>
sage: [type, type]
[<type 'type'>, <type 'type'>]
sage: import types
sage: types.ClassType('name', (), {})
<class __main__.name at 0x...>
sage: types.TypeType
<type 'type'>
sage: types.BuiltinFunctionType
<type 'builtin_function_or_method'>
sage: def foo(): pass
sage: foo
<function foo at 0x...>
Pretty print obj
This is the only method that outside code should invoke.
INPUT:
OUTPUT:
String representation for object.
EXAMPLES:
sage: from sage.repl.display.pretty_print import SagePrettyPrinter
sage: import StringIO
sage: stream = StringIO.StringIO()
sage: SagePrettyPrinter(stream, 78, '\n').pretty([type, 123, 'foo'])
sage: stream.getvalue()
"[<type 'type'>,"
Return whether we are currently at the top level.
OUTPUT:
Boolean. Whether we are currently pretty-printing an object at the outermost level (True), or whether the object is inside a container (False).
EXAMPLES:
sage: from sage.repl.display.pretty_print import SagePrettyPrinter
sage: import StringIO
sage: stream = StringIO.StringIO()
sage: spp = SagePrettyPrinter(stream, 78, '\n')
sage: spp.toplevel()
True

This is also used in the emacs-mode.
