The ``__pypy__`` module
=======================
The ``__pypy__`` module is the main entry point to special features provided
by PyPy's standard interpreter. Its content depends on :doc:`configuration options <config/index>`
which may add new functionality and functions whose existence or non-existence
indicates the presence of such features.
Generally available functionality
---------------------------------
- ``internal_repr(obj)``: return the interpreter-level representation of an
object.
- ``bytebuffer(length)``: return a new read-write buffer of the given length.
It works like a simplified array of characters (actually, depending on the
configuration the ``array`` module internally uses this).
- ``attach_gdb()``: start a GDB at the interpreter-level (or a PDB before translation).
Transparent Proxy Functionality
-------------------------------
If :ref:`transparent proxies <tproxy>` are enabled (with :config:`objspace.std.withtproxy`)
the following functions are put into ``__pypy__``:
- ``tproxy(typ, controller)``: Return something that looks like it is of type
typ. Its behaviour is completely controlled by the controller. See the docs
about :ref:`transparent proxies <tproxy>` for detail.
- ``get_tproxy_controller(obj)``: If obj is really a transparent proxy, return
its controller. Otherwise return None.
Functionality available on py.py (not after translation)
--------------------------------------------------------
- ``isfake(obj)``: returns True if ``obj`` is faked.
