Support new IGNORE-INVALID-SEQUENCESP argument, #'query-coding-region.
lisp/ChangeLog addition:
2009-02-07 Aidan Kehoe <kehoea@parhasard.net>
* coding.el (query-coding-clear-highlights):
Rename the BUFFER argument to BUFFER-OR-STRING, describe it as
possibly being a string in its documentation.
(default-query-coding-region):
Add a new IGNORE-INVALID-SEQUENCESP argument, document that this
function does not support it.
Bind case-fold-search to nil, we don't want this to influence what the
function thinks is encodable or not.
(query-coding-region):
Add a new IGNORE-INVALID-SEQUENCESP argument, document what it
does; reflect this new argument in the associated compiler macro.
(query-coding-string):
Add a new IGNORE-INVALID-SEQUENCESP argument, document what it
does. Support the HIGHLIGHT argument correctly.
* unicode.el (unicode-query-coding-region):
Add a new IGNORE-INVALID-SEQUENCESP argument, document what it
does, implement this. Document a potential problem.
Use #'query-coding-clear-highlights instead of reimplementing it
ourselves.
Remove some debugging messages.
* mule/arabic.el (iso-8859-6):
* mule/cyrillic.el (iso-8859-5):
* mule/greek.el (iso-8859-7):
* mule/hebrew.el (iso-8859-8):
* mule/latin.el (iso-8859-2):
* mule/latin.el (iso-8859-3):
* mule/latin.el (iso-8859-4):
* mule/latin.el (iso-8859-14):
* mule/latin.el (iso-8859-15):
* mule/latin.el (iso-8859-16):
* mule/latin.el (iso-8859-9):
* mule/latin.el (windows-1252):
* mule/mule-coding.el (iso-8859-1):
Avoid the assumption that characters not given an explicit mapping
in these coding systems map to the ISO 8859-1 characters
corresponding to the octets on disk; this makes it much more
reasonable to implement the IGNORE-INVALID-SEQUENCESP argument to
query-coding-region.
* mule/mule-cmds.el (set-language-info):
Correct the docstring.
* mule/mule-cmds.el (finish-set-language-environment):
Treat invalid Unicode sequences produced from
invalid-sequence-coding-system and corresponding to control
characters the same as control characters in redisplay.
* mule/mule-cmds.el:
Document that encode-coding-char is available in coding.el
* mule/mule-coding.el (make-8-bit-generate-helper):
Change to return the both the encode-program generated and the
relevant non-ASCII charset; update the docstring to reflect this.
* mule/mule-coding.el
(make-8-bit-generate-encode-program-and-skip-chars-strings):
Rename this function; have it return skip-chars-strings as well as
the encode program. Have these skip-chars-strings use ranges for
charsets, where possible.
* mule/mule-coding.el (make-8-bit-create-decode-encode-tables):
Revise this to allow people to specify explicitly characters that
should be undefined (= corresponding to keys in
unicode-error-default-translation-table), and treating unspecified
octets above #x7f as undefined by default.
* mule/mule-coding.el (8-bit-fixed-query-coding-region):
Add a new IGNORE-INVALID-SEQUENCESP argument, implement support
for it using the 8-bit-fixed-invalid-sequences-skip-chars coding
system property; remove some debugging messages.
* mule/mule-coding.el (make-8-bit-coding-system):
This function is dumped, autoloading it makes no sense.
Document what happens when characters above #x7f are not
specified, implement this.
* mule/vietnamese.el:
Correct spelling.
tests/ChangeLog addition:
2009-02-07 Aidan Kehoe <kehoea@parhasard.net>
* automated/query-coding-tests.el:
Add FAILING-CASE arguments to the Assert calls, making #'q-c-debug
mostly unnecessary. Remove #'q-c-debug.
Add new tests that use the IGNORE-INVALID-SEQUENCESP argument to
#'query-coding-region; rework the existing ones to respect it.
