Codec registry and support functions¶
-
int PyCodec_Register(PyObject *search_function)¶
- Part of the Stable ABI.
Register a new codec search function.
As 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)¶
- Part of the Stable ABI since version 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.
Ajouté dans la version 3.10.
-
int PyCodec_KnownEncoding(const char *encoding)¶
- Part of the Stable ABI.
Return
1
or0
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)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
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 aLookupError
if no encoder can be found.
-
PyObject *PyCodec_Decode(PyObject *object, const char *encoding, const char *errors)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
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 aLookupError
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 KeyError
is set
and NULL
returned.
-
PyObject *PyCodec_Encoder(const char *encoding)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Get an encoder function for the given encoding.
-
PyObject *PyCodec_Decoder(const char *encoding)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Get a decoder function for the given encoding.
-
PyObject *PyCodec_IncrementalEncoder(const char *encoding, const char *errors)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Get an
IncrementalEncoder
object for the given encoding.
-
PyObject *PyCodec_IncrementalDecoder(const char *encoding, const char *errors)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Get an
IncrementalDecoder
object for the given encoding.
-
PyObject *PyCodec_StreamReader(const char *encoding, PyObject *stream, const char *errors)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Get a
StreamReader
factory function for the given encoding.
-
PyObject *PyCodec_StreamWriter(const char *encoding, PyObject *stream, const char *errors)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Get a
StreamWriter
factory function for the given encoding.
Registry API for Unicode encoding error handlers¶
-
int PyCodec_RegisterError(const char *name, PyObject *error)¶
- Part of the Stable ABI.
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
orUnicodeTranslateError
that holds information about the problematic sequence of characters or bytes and their offset in the original string (see Objets exception Unicode 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)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
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)¶
- Valeur de retour : toujours NULL. Part of the Stable ABI.
Raise exc as an exception.
-
PyObject *PyCodec_IgnoreErrors(PyObject *exc)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Ignore the unicode error, skipping the faulty input.
-
PyObject *PyCodec_ReplaceErrors(PyObject *exc)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Replace the unicode encode error with
?
orU+FFFD
.
-
PyObject *PyCodec_XMLCharRefReplaceErrors(PyObject *exc)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Replace the unicode encode error with XML character references.
-
PyObject *PyCodec_BackslashReplaceErrors(PyObject *exc)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI.
Replace the unicode encode error with backslash escapes (
\x
,\u
and\U
).
-
PyObject *PyCodec_NameReplaceErrors(PyObject *exc)¶
- Valeur de retour : nouvelle référence. Part of the Stable ABI since version 3.7.
Replace the unicode encode error with
\N{...}
escapes.Ajouté dans la version 3.5.
