Codec registry and support functions

int PyCodec_Register(PyObject *search_function)

قسمتی از ABI پایدار.

Register a new codec search function.

As a side effect, this tries to load the encodings package, if not yet done, to make sure that it is always first in the list of search functions.

int PyCodec_Unregister(PyObject *search_function)

قسمتی از ABI پایدار از نسخه‌ی 3.10.

Unregister a codec search function and clear the registry's cache. If the search function is not registered, do nothing. Return 0 on success. Raise an exception and return -1 on error.

Added in version 3.10.

int PyCodec_KnownEncoding(const char *encoding)

قسمتی از ABI پایدار.

Return 1 or 0 depending on whether there is a registered codec for the given encoding. This function always succeeds.

PyObject *PyCodec_Encode(PyObject *object, const char *encoding, const char *errors)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

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 LookupError if no encoder can be found.

PyObject *PyCodec_Decode(PyObject *object, const char *encoding, const char *errors)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

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 LookupError if no decoder 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 KeyError is set and NULL returned.

PyObject *PyCodec_Encoder(const char *encoding)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Get an encoder function for the given encoding.

PyObject *PyCodec_Decoder(const char *encoding)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Get a decoder function for the given encoding.

PyObject *PyCodec_IncrementalEncoder(const char *encoding, const char *errors)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Get an IncrementalEncoder object for the given encoding.

PyObject *PyCodec_IncrementalDecoder(const char *encoding, const char *errors)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Get an IncrementalDecoder object for the given encoding.

PyObject *PyCodec_StreamReader(const char *encoding, PyObject *stream, const char *errors)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Get a StreamReader factory function for the given encoding.

PyObject *PyCodec_StreamWriter(const char *encoding, PyObject *stream, const char *errors)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Get a StreamWriter factory function for the given encoding.

Registry API for Unicode encoding error handlers

int PyCodec_RegisterError(const char *name, PyObject *error)

قسمتی از ABI پایدار.

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 UnicodeEncodeError, UnicodeDecodeError or UnicodeTranslateError that holds information about the problematic sequence of characters or bytes and their offset in the original string (see Unicode Exception Objects 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.

PyObject *PyCodec_LookupError(const char *name)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

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.

PyObject *PyCodec_StrictErrors(PyObject *exc)

مقدار بازگشتی: همیشه NULL. قسمتی از ABI پایدار.

Raise exc as an exception.

PyObject *PyCodec_IgnoreErrors(PyObject *exc)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Ignore the unicode error, skipping the faulty input.

PyObject *PyCodec_ReplaceErrors(PyObject *exc)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Replace the unicode encode error with ? or U+FFFD.

PyObject *PyCodec_XMLCharRefReplaceErrors(PyObject *exc)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Replace the unicode encode error with XML character references.

PyObject *PyCodec_BackslashReplaceErrors(PyObject *exc)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار.

Replace the unicode encode error with backslash escapes (\x, \u and \U).

PyObject *PyCodec_NameReplaceErrors(PyObject *exc)

مقدار بازگشتی: مرجع جدید. قسمتی از ABI پایدار از نسخه‌ی 3.7.

Replace the unicode encode error with \N{...} escapes.

Added in version 3.5.

Codec utility variables

const char *Py_hexdigits

A string constant containing the lowercase hexadecimal digits: "0123456789abcdef".

Added in version 3.3.
