BASIC IDEA: Further fixing up uses of char * and CIbyte *
to reflect their actual semantics; Mule-izing some code;
redoing of the not-yet-working code to handle message translation.
Clean up code to handle message-translation (not yet working).
Create separate versions of build_msg_string() for working with
Ibyte *, CIbyte *, and Ascbyte * arguments. Assert that Ascbyte *
arguments are pure-ASCII. Make build_msg_string() be the same
as build_msg_ascstring(). Create same three versions of GETTEXT()
and DEFER_GETTEXT(). Also create build_defer_string() and
variants for the equivalent of DEFER_GETTEXT() when building a
string. Remove old CGETTEXT(). Clean up code where GETTEXT(),
DEFER_GETTEXT(), build_msg_string(), etc. was being called and
introduce some new calls to build_msg_string(), etc. Remove
GETTEXT() from calls to weird_doc() -- we assume that the
message snarfer knows about weird_doc(). Remove uses of
DEFER_GETTEXT() from error messages in sysdep.c and instead use
special comments /* @@@begin-snarf@@@ */ and /* @@@end-snarf@@@ */
that the message snarfer presumably knows about.
Create build_ascstring() and use it in many instances in place
of build_string(). The purpose of having Ascbyte * variants is
to make the code more self-documenting in terms of what sort of
semantics is expected for char * strings. In fact in the process
of looking for uses of build_string(), much improperly Mule-ized
was discovered.
Mule-ize a lot of code as described in previous paragraph,
e.g. in sysdep.c.
Make the error functions take Ascbyte * strings and fix up a
couple of places where non-pure-ASCII strings were being passed in
(file-coding.c, mule-coding.c, unicode.c). (It's debatable whether
we really need to make the error functions work this way. It
helps catch places where code is written in a way that message
translation won't work, but we may well never implement message
translation.)
Make staticpro() and friends take Ascbyte * strings instead of
raw char * strings. Create a const_Ascbyte_ptr dynarr type
to describe what's held by staticpro_names[] and friends,
create pdump descriptions for const_Ascbyte_ptr dynarrs, and
use them in place of specially-crafted staticpro descriptions.
Mule-ize certain other functions (e.g. x_event_name) by correcting
raw use of char * to Ascbyte *, Rawbyte * or another such type,
and raw use of char[] buffers to another type (usually Ascbyte[]).
Change many uses of write_c_string() to write_msg_string(),
write_ascstring(), etc.
Mule-ize emodules.c, emodules.h, sysdll.h.
Fix some un-Mule-ized code in intl-win32.c.
A comment in event-Xt.c and the limitations of the message
snarfer (make-msgfile or whatever) is presumably incorrect --
it should be smart enough to handle function calls spread over
more than one line. Clean up code in event-Xt.c that was
written awkwardly for this reason.
In config.h.in, instead of NEED_ERROR_CHECK_TYPES_INLINES,
create a more general XEMACS_DEFS_NEEDS_INLINE_DECLS to
indicate when inlined functions need to be declared in
xemacs.defs.in.in, and make use of it in xemacs.defs.in.in.
We need to do this because postgresql.c now calls qxestrdup(),
which is an inline function.
Make nconc2() and other such functions MODULE_API and put
them in xemacs.defs.in.in since postgresql.c now uses them.
Clean up indentation in lread.c and a few other places.
In text.h, document ASSERT_ASCTEXT_ASCII() and
ASSERT_ASCTEXT_ASCII_LEN(), group together the stand-in
encodings and add some more for DLL symbols, function and
variable names, etc.
