Codec registry and support functions
|
||||
====================================
|
||||
|
||||
.. cfunction:: int PyCodec_Register(PyObject *search_function)
|
||||
|
||||
Register a new codec search function.
|
||||
|
||||
As side effect, this tries to load the :mod:`encodings` package, if not yet
|
||||
done, to make sure that it is always first in the list of search functions.
|
||||
|
||||
.. cfunction:: int PyCodec_KnownEncoding(const char *encoding)
|
||||
|
||||
Return ``1`` or ``0`` depending on whether there is a registered codec for
|
||||
the given *encoding*.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_Encode(PyObject *object, const char *encoding, const char *errors)
|
||||
|
||||
Generic codec based encoding API.
|
||||
|
||||
*object* is passed through the encoder function found for the given
|
||||
*encoding* using the error handling method defined by *errors*. *errors* may
|
||||
be *NULL* to use the default method defined for the codec. Raises a
|
||||
:exc:`LookupError` if no encoder can be found.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_Decode(PyObject *object, const char *encoding, const char *errors)
|
||||
|
||||
Generic codec based decoding API.
|
||||
|
||||
*object* is passed through the decoder function found for the given
|
||||
*encoding* using the error handling method defined by *errors*. *errors* may
|
||||
be *NULL* to use the default method defined for the codec. Raises a
|
||||
:exc:`LookupError` if no encoder can be found.
|
||||
|
||||
|
||||
Codec lookup API
|
||||
----------------
|
||||
|
||||
In the following functions, the *encoding* string is looked up converted to all
|
||||
lower-case characters, which makes encodings looked up through this mechanism
|
||||
effectively case-insensitive. If no codec is found, a :exc:`KeyError` is set
|
||||
and *NULL* returned.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_Encoder(const char *encoding)
|
||||
|
||||
Get an encoder function for the given *encoding*.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_Decoder(const char *encoding)
|
||||
|
||||
Get a decoder function for the given *encoding*.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_IncrementalEncoder(const char *encoding, const char *errors)
|
||||
|
||||
Get an :class:`IncrementalEncoder` object for the given *encoding*.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_IncrementalDecoder(const char *encoding, const char *errors)
|
||||
|
||||
Get an :class:`IncrementalDecoder` object for the given *encoding*.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_StreamReader(const char *encoding, PyObject *stream, const char *errors)
|
||||
|
||||
Get a :class:`StreamReader` factory function for the given *encoding*.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_StreamWriter(const char *encoding, PyObject *stream, const char *errors)
|
||||
|
||||
Get a :class:`StreamWriter` factory function for the given *encoding*.
|
||||
|
||||
|
||||
Registry API for Unicode encoding error handlers
|
||||
------------------------------------------------
|
||||
|
||||
.. cfunction:: int PyCodec_RegisterError(const char *name, PyObject *error)
|
||||
|
||||
Register the error handling callback function *error* under the given *name*.
|
||||
This callback function will be called by a codec when it encounters
|
||||
unencodable characters/undecodable bytes and *name* is specified as the error
|
||||
parameter in the call to the encode/decode function.
|
||||
|
||||
The callback gets a single argument, an instance of
|
||||
:exc:`UnicodeEncodeError`, :exc:`UnicodeDecodeError` or
|
||||
:exc:`UnicodeTranslateError` that holds information about the problematic
|
||||
sequence of characters or bytes and their offset in the original string (see
|
||||
:ref:`unicodeexceptions` for functions to extract this information). The
|
||||
callback must either raise the given exception, or return a two-item tuple
|
||||
containing the replacement for the problematic sequence, and an integer
|
||||
giving the offset in the original string at which encoding/decoding should be
|
||||
resumed.
|
||||
|
||||
Return ``0`` on success, ``-1`` on error.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_LookupError(const char *name)
|
||||
|
||||
Lookup the error handling callback function registered under *name*. As a
|
||||
special case *NULL* can be passed, in which case the error handling callback
|
||||
for "strict" will be returned.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_StrictErrors(PyObject *exc)
|
||||
|
||||
Raise *exc* as an exception.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_IgnoreErrors(PyObject *exc)
|
||||
|
||||
Ignore the unicode error, skipping the faulty input.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_ReplaceErrors(PyObject *exc)
|
||||
|
||||
Replace the unicode encode error with ``?`` or ``U+FFFD``.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_XMLCharRefReplaceErrors(PyObject *exc)
|
||||
|
||||
Replace the unicode encode error with XML character references.
|
||||
|
||||
.. cfunction:: PyObject* PyCodec_BackslashReplaceErrors(PyObject *exc)
|
||||
|
||||
Replace the unicode encode error with backslash escapes (``\x``, ``\u`` and
|
||||
``\U``).

This module provides an implementation of the heap queue algorithm, also known
|
||||
as the priority queue algorithm.
|
||||
|
||||
Heaps are arrays for which ``heap[k] <= heap[2*k+1]`` and ``heap[k] <=
|
||||
heap[2*k+2]`` for all *k*, counting elements from zero. For the sake of
|
||||
comparison, non-existing elements are considered to be infinite. The
|
||||
interesting property of a heap is that ``heap[0]`` is always its smallest
|
||||
element.
|
||||
Heaps are binary trees for which every parent node has a value less than or
|
||||
equal to any of its children. This implementation uses arrays for which
|
||||
``heap[k] <= heap[2*k+1]`` and ``heap[k] <= heap[2*k+2]`` for all *k*, counting
|
||||
elements from zero. For the sake of comparison, non-existing elements are
|
||||
considered to be infinite. The interesting property of a heap is that its
|
||||
smallest element is always the root, ``heap[0]``.
|
||||
|
||||
The API below differs from textbook heap algorithms in two aspects: (a) We use
|

zero-based indexing. This makes the relationship between the index for a node
