1.3: Internationalization
=========================
-Q1.3.1: What is the status of XEmacs v20?
------------------------------------------
+Q1.3.1: What is the status of internationalization support aka MULE (including Asian language support?
+------------------------------------------------------------------------------------------------------
- XEmacs v20 is the version of XEmacs that includes MULE
-(Asian-language) support. XEmacs 20.0 was released in February 1997,
-followed by XEmacs 20.2 in May, XEmacs 20.3 in November and XEmacs 20.4
-in February 1998. When compiled without MULE support, 20.4 is
-approximately as stable as 19.16, and probably faster (due to
-additional optimization work.)
-
- As of XEmacs 20.3, version 20 is _the_ supported version of XEmacs.
-This means that 19.16 will optionally receive stability fixes (if any),
-but that all the real development work will be done on the v20 tree.
-
- The incompatible changes in XEmacs 20 include the additional
-byte-codes, new primitive data types (`character', `char-table', and
-`range-table'). This means that the character-integer equivalence
-inherent to all the previous Emacs and XEmacs releases no longer
-applies.
-
- However, to avoid breaking old code, many functions that should
-normally accept characters work with integers, and vice versa. For more
-information, see the Lisp reference manual. Here is a relevant excerpt,
-for your convenience.
-
- In XEmacs version 19, and in all versions of FSF GNU Emacs, a
- "character" in XEmacs Lisp is nothing more than an integer. This
- is yet another holdover from XEmacs Lisp's derivation from
- vintage-1980 Lisps; modern versions of Lisp consider this
- equivalence a bad idea, and have separate character types. In
- XEmacs version 20, the modern convention is followed, and
- characters are their own primitive types. (This change was
- necessary in order for MULE, i.e. Asian-language, support to be
- correctly implemented.)
-
- Even in XEmacs version 20, remnants of the equivalence between
- characters and integers still exist; this is termed the "char-int
- confoundance disease". In particular, many functions such as `eq',
- `equal', and `memq' have equivalent functions (`old-eq',
- `old-equal', `old-memq', etc.) that pretend like characters are
- integers are the same. Byte code compiled under any version 19
- Emacs will have all such functions mapped to their `old-'
- equivalents when the byte code is read into XEmacs 20. This is to
- preserve compatibility--Emacs 19 converts all constant characters
- to the equivalent integer during byte-compilation, and thus there
- is no other way to preserve byte-code compatibility even if the
- code has specifically been written with the distinction between
- characters and integers in mind.
-
- Every character has an equivalent integer, called the "character
- code". For example, the character `A' is represented as the
- integer 65, following the standard ASCII representation of
- characters. If XEmacs was not compiled with MULE support, the
- range of this integer will always be 0 to 255--eight bits, or one
- byte. (Integers outside this range are accepted but silently
- truncated; however, you should most decidedly _not_ rely on this,
- because it will not work under XEmacs with MULE support.) When
- MULE support is present, the range of character codes is much
- larger. (Currently, 19 bits are used.)
-
- FSF GNU Emacs uses kludgy character codes above 255 to represent
- keyboard input of ASCII characters in combination with certain
- modifiers. XEmacs does not use this (a more general mechanism is
- used that does not distinguish between ASCII keys and other keys),
- so you will never find character codes above 255 in a non-MULE
- XEmacs.
-
- Individual characters are not often used in programs. It is far
- more common to work with _strings_, which are sequences composed of
- characters.
+ Both the stable and development versions of XEmacs include
+internationalization support (aka MULE). MULE currently works on UNIX
+and Linux systems; work for supporting MULE on Windows operating systems
+is in progress. Binaries compiled without MULE support run faster than
+MULE capable XEmacsen.

+
+Q2.0.2: XEmacs is too big
+-------------------------
+
+ The space required by the installation directories can be reduced
+dramatically if desired. Gzip all the .el files. Remove all the
+packages you'll never want to use. Remove the TexInfo manuals. Remove
+the Info (and use just hardcopy versions of the manual). Remove most
+of the stuff in etc. Remove or gzip all the source code. Gzip or
+remove the C source code. Configure it so that copies are not made of
+the support lisp.
+
+ These are all Emacs Lisp source code and bytecompiled object code.
+You may safely gzip everything named *.el here. You may remove any
+package you don't use. _Nothing bad will happen if you delete a package
+that you do not use_. You must be sure you do not use it though, so be
+conservative at first.
+
+ Possible candidates for deletion include w3, games, hyperbole, mh-e,
+hm-html-menus, vm, viper, oobr, gnus, etc. Ask yourself, _Do I ever
+want to use this package?_ If the answer is no, then it is a candidate
+for removal.
+
+ First, gzip all the .el files. Then go about package by package and
+start gzipping the .elc files. Then run XEmacs and do whatever it is
+you normally do. If nothing bad happens, then delete the directory. Be
+conservative about deleting directories, and it would be handy to have a
+backup around in case you get too zealous.
+
+ `prim', `modes', `packages', and `utils' are four directories you
+definitely do *not* want to delete, although certain packages can be
+removed from them if you do not use them.
+
+ Online texinfo sources in the `info' can either be compressed them
+or remove them. In either case, `C-h i' (info mode) will no longer
+work.

+Q2.0.3: Compiling XEmacs with Netaudio.
+---------------------------------------
+
+ What is the best way to compile XEmacs with the netaudio system,
+since I have got the netaudio system compiled but installed at a weird
+place, I am not root. Also in the READMEs it does not say anything
+about compiling with the audioserver?
+
+ You should only need to add some stuff to the configure command line.
+To tell it to compile in netaudio support: `--with-sound=both', or
+`--with-sound=nas' if you don't want native sound support for some
+reason.) To tell it where to find the netaudio includes and libraries:
+
+ --site-libraries=WHATEVER
+ --site-includes=WHATEVER
+
+ Then (fingers crossed) it should compile and it will use netaudio if
+you have a server running corresponding to the X server. The netaudio
+server has to be there when XEmacs starts. If the netaudio server goes
+away and another is run, XEmacs should cope (fingers crossed, error
+handling in netaudio isn't perfect).
+
+ BTW, netaudio has been renamed as it has a name clash with something
+else, so if you see references to NAS or Network Audio System, it's the
+same thing. It also might be found at
+`ftp://ftp.x.org/contrib/audio/nas/'.
+
