of encodings. Skip modules that don't have a getregentry function.

Marc-André Lemburg a0af63b242 Corrected import behaviour for codecs which live outside the encodings
package.

Marc-André Lemburg 462004e90a Add IANA character set aliases to the encodings alias dictionary
and make alias lookup lazy.

Note that only those IANA character set aliases were added for which
we actually have codecs in the encodings package.

Marc-André Lemburg 26e3b681b2 Patch #462635 by Andrew Kuchling correcting bugs in the new
codecs -- the self argument does matter for Python functions (it
does not for C functions which most other codecs use).

Marc-André Lemburg 816a1b75b7 Fixed search function error reporting in the encodings package
__init__.py module to raise errors which can be catched as LookupErrors
as well as SystemErrors.

Modified the error messages to include more information about the
failing module.

Martin v. Löwis 9b75dca192 Expose nl_langinfo through locale where available. 2001-08-10 13:58:50 +00:00
Marc-André Lemburg 92b550cdd8 This patch by Martin v. Loewis changes the UTF-16 codec to only
write a BOM at the start of the stream and also to only read it as
BOM at the start of a stream.

Subsequent reading/writing of BOMs will read/write the BOM as ZWNBSP
character. This is in sync with the Unicode specifications.

Note that UTF-16 files will now *have* to start with a BOM mark
in order to be readable by the codec.

Martin v. Löwis 13b8bc5478 Patch #429957: Add support for cp1140, which is identical to cp037,
with the addition of the euro character.
Also added a few EDBDIC aliases.

Mark Hammond 194bfb2805 Add some useful Windows encodings - patch #423221. 2001-06-04 02:31:23 +00:00
Marc-André Lemburg 716cf91839 Moved the encoding map building logic from the individual mapping
codec files to codecs.py and added logic so that multi mappings
in the decoding maps now result in mappings to None (undefined mapping)
in the encoding maps.

Guido van Rossum acfdf156aa Add quoted-printable codec 2001-05-15 15:34:07 +00:00
Marc-André Lemburg 2d9204199f This patch changes the way the string .encode() method works slightly
and introduces a new method .decode().

The major change is that strg.encode() will no longer try to convert
Unicode returns from the codec into a string, but instead pass along
the Unicode object as-is. The same is now true for all other codec
return types. The underlying C APIs were changed accordingly.

Note that even though this does have the potential of breaking
existing code, the chances are low since conversion from Unicode
previously took place using the default encoding which is normally
set to ASCII rendering this auto-conversion mechanism useless for
most Unicode encodings.

The good news is that you can now use .encode() and .decode() with
much greater ease and that the door was opened for better accessibility
of the builtin codecs.

As demonstration of the new feature, the patch includes a few new
codecs which allow string to string encoding and decoding (rot13,
hex, zip, uu, base64).

Marc-André Lemburg a866df806d This patch changes the default behaviour of the builtin charmap
codec to not apply Latin-1 mappings for keys which are not found
in the mapping dictionaries, but instead treat them as undefined
mappings.

The patch was originally written by Martin v. Loewis with some
additional (cosmetic) changes and an updated test script
by Marc-Andre Lemburg.

The standard codecs were recreated from the most current files
available at the Unicode.org site using the Tools/scripts/gencodec.py
tool.

This patch closes the bugs #116285 and #119960.

Marc-André Lemburg 988ad2bdff Changed .getaliases() support to register the new aliases in the
encodings package aliases mapping dictionary rather than in the
internal cache used by the search function.

This enables aliases to take advantage of the full normalization
process applied to encoding names which was previously not available.

The patch restricts alias registration to new aliases. Existing
aliases cannot be overridden anymore.

Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Marc-André Lemburg 7ebb92ea66 Marc-Andre Lemburg <mal@lemburg.com>:
Removed import of string module -- use string methods directly.
Thanks to Finn Bock.

Marc-André Lemburg 4fd73f0465 Marc-Andre Lemburg <mal@lemburg.com>:
Added some more codec aliases. Some of them are needed by the
new locale.py encoding support.

Marc-André Lemburg 54480d300a New codec which always raises an exception when used. This
codec can be used to effectively switch off string coercion
to Unicode.

Guido van Rossum 9e896b37c7 Marc-Andre's third try at this bulk patch seems to work (except that
his copy of test_contains.py seems to be broken -- the lines he
deleted were already absent).  Checkin messages:


New Unicode support for int(), float(), complex() and long().

- new APIs PyInt_FromUnicode() and PyLong_FromUnicode()
- added support for Unicode to PyFloat_FromString()
- new encoding API PyUnicode_EncodeDecimal() which converts
  Unicode to a decimal char* string (used in the above new
  APIs)
- shortcuts for calls like int(<int object>) and float(<float obj>)
- tests for all of the above

Unicode compares and contains checks:
- comparing Unicode and non-string types now works; TypeErrors
  are masked, all other errors such as ValueError during
  Unicode coercion are passed through (note that PyUnicode_Compare
  does not implement the masking -- PyObject_Compare does this)
- contains now works for non-string types too; TypeErrors are
  masked and 0 returned; all other errors are passed through

Better testing support for the standard codecs.

Misc minor enhancements, such as an alias dbcs for the mbcs codec.

Changes:
- PyLong_FromString() now applies the same error checks as
  does PyInt_FromString(): trailing garbage is reported
  as error and not longer silently ignored. The only characters
  which may be trailing the digits are 'L' and 'l' -- these
  are still silently ignored.
- string.ato?() now directly interface to int(), long() and
  float(). The error strings are now a little different, but
  the type still remains the same. These functions are now
  ready to get declared obsolete ;-)
- PyNumber_Int() now also does a check for embedded NULL chars
  in the input string; PyNumber_Long() already did this (and
  still does)

Followed by:

Looks like I've gone a step too far there... (and test_contains.py
seem to have a bug too).

I've changed back to reporting all errors in PyUnicode_Contains()
and added a few more test cases to test_contains.py (plus corrected
the join() NameError).

Guido van Rossum 68895ed70c Marc-Andre Lemburg: use all lowercase names. 2000-03-31 17:23:18 +00:00
Guido van Rossum 24bdb0474f Marc-Andre Lemburg:
The attached patch set includes a workaround to get Python with
Unicode compile on BSDI 4.x (courtesy Thomas Wouters; the cause
is a bug in the BSDI wchar.h header file) and Python interfaces
for the MBCS codec donated by Mark Hammond.

Also included are some minor corrections w/r to the docs of
the new "es" and "es#" parser markers (use PyMem_Free() instead
of free(); thanks to Mark Hammond for finding these).

The unicodedata tests are now in a separate file
(test_unicodedata.py) to avoid problems if the module cannot
be found.

Barry Warsaw 51ac58039f On 17-Mar-2000, Marc-Andre Lemburg said:
Attached you find an update of the Unicode implementation.

    The patch is against the current CVS version. I would appreciate
    if someone with CVS checkin permissions could check the changes
    in.

    The patch contains all bugs and patches sent this week and also
    fixes a leak in the codecs code and a bug in the free list code
    for Unicode objects (which only shows up when compiling Python
    with Py_DEBUG; thanks to MarkH for spotting this one).
