5 *** What is XEmacs?
|
|
|
6
|
|
|
7 XEmacs is a powerful, highly customizable open source text editor and
|
|
|
8 application development system, with full GUI support. It is protected
|
|
|
9 under the GNU Public License and related to other versions of Emacs, in
|
|
|
10 particular GNU Emacs. Its emphasis is on modern graphical user
|
|
|
11 interface support and an open software development model, similar to
|
|
|
12 Linux. XEmacs has an active development community numbering in the
|
|
|
13 hundreds (and thousands of active beta testers on top of this), and runs
|
|
|
14 on all versions of MS Windows, on Linux, and on nearly every other
|
|
|
15 version of Unix in existence. Support for XEmacs has been supplied by
|
|
|
16 Sun Microsystems, University of Illinois, Lucid, ETL/Electrotechnical
|
|
|
17 Laboratory, Amdahl Corporation, BeOpen, and others, as well as the
|
|
|
18 unpaid time of a great number of individual developers.

22 *** What platforms does it run on?
|
|
|
23
|
|
|
24 -- MS Windows (It has been tested on NT, 2000, 95, 98, and ME; you
|
|
|
25 can also compile Cygwin and MinGW versions.)
|
|
|
26 -- Unix (It is regularly tested on Linux, Solaris, SunOS, HP/UX,
|
|
|
27 FreeBSD, OpenBSD, BSD/OS aka BSDI, Tru64 aka DEC/OSF, SCO5,
|
|
|
28 and probably others. It should work on all versions of Unix
|
|
|
29 created in the last 10 years or so, perhaps with a bit of
|
|
|
30 work on more obscure platforms to correct bit-rot. It uses
|
|
|
31 a sophisticated configuration system to auto-detect zillions
|
|
|
32 of features that are implemented differently in different
|
|
|
33 versions of Unix, so it will probably work on your vendor's
|
|
|
34 version, possibly with a bit of tweaking, even if we've
|
|
|
35 never heard of it.)
|
|
|
36 -- MacOS/X (As an X Windows application. Unfortunately there is no
|
|
|
37 support currently for MacOS-specific features.)
|
|
|
38
|
|
|
39 There is also a port of XEmacs 19.14 (an older version, circa 1996)
|
|
|
40 for all versions of MacOS, with extensive support for MacOS-specific
|
|
|
41 features. See the FAQ for more details.
|
|
|
42
|
|
|
43 There are rumors of an in-progress port to OS/2. See the FAQ.
|
|
|
44
|
|
|
45 XEmacs will probably never work on MS/DOS or Windows 3.1, and we're
|
|
|
46 not particularly interested in patches for these platforms, as they
|
|
|
47 would introduce huge amounts of code clutter due to the woefully
|
|
|
48 underfeatured nature of these systems. (See GNU Emacs for a port to
|
|
|
49 MS/DOS.)

72 There are numerous mailing lists for discussion of XEmacs. The

|
73 current description of these lists can be found at
|
|
|
74 http://www.xemacs.org/Lists/, or see `etc/MAILINGLISTS'. General
|

97 *** How do I deal with bugs or with problems building, installing, or running?
|
|
|
98
|
|
|
99 The file `PROBLEMS' contains information on many common problems that
|
|
|
100 occur in building, installing and running XEmacs.
|
|
|
101
|
|
|
102 Reports of bugs in XEmacs should be sent to xemacs-beta@xemacs.org.
|
|
|
103 You can also post to the newsgroup comp.emacs.xemacs (or equivalentlt,
|
|
|
104 send to the mailing list xemacs@xemacs.org), but it is less likely
|
|
|
105 that the developers will see it in a timely fashion. See the "Bugs"
|
|
|
106 section of the XEmacs manual for more information on how to report
|
|
|
107 bugs. (The file `BUGS' in this directory explains how you can find
|
|
|
108 and read that section using the Info files that come with XEmacs.)
|
|
|
109 See `etc/MAILINGLISTS' for more information on mailing lists relating
|
|
|
110 to XEmacs.

|
|
|
113 *** What's the basic layout of the code?
|
|
0
|
114
|
|
|
115 The file `configure' is a shell script to acclimate XEmacs to the
|
|
|
116 oddities of your processor and operating system. It will create a
|
|
|
117 file named `Makefile' (a script for the `make' program), which helps
|
|
|
118 automate the process of building and installing emacs. See INSTALL
|
|
|
119 for more detailed information.
|
|
|
120
|
|
|
121 The file `configure.in' is the input used by the autoconf program to
|
|
|
122 construct the `configure' script. Since XEmacs has configuration
|
|
|
123 requirements that autoconf can't meet, `configure.in' uses an unholy
|
|
|
124 marriage of custom-baked configuration code and autoconf macros; it
|
|
|
125 may be wise to avoid rebuilding `configure' from `configure.in' when
|
|
|
126 possible.
|
|
|
127
|
|
|
128 The file `Makefile.in' is a template used by `configure' to create
|
|
|
129 `Makefile'.
|
|
|
130
|
|
|
131 There are several subdirectories:
|
|
|
132
|
|
623
|
133 `src' holds the C code for XEmacs (the XEmacs Lisp interpreter and its
|
|
0
|
134 primitives, the redisplay code, and some basic editing functions).
|
|
623
|
135 `lisp' holds the XEmacs Lisp code for XEmacs (most everything else).
|
|
0
|
136 `lib-src' holds the source code for some utility programs for use by
|
|
|
137 or with XEmacs, like movemail and etags.
|
|
|
138 `etc' holds miscellaneous architecture-independent data files
|
|
|
139 XEmacs uses, like the tutorial text and the Zippy the Pinhead quote
|
|
|
140 database. The contents of the `lisp', `info' and `man'
|
|
|
141 subdirectories are architecture-independent too.
|
|
623
|
142 `lwlib' holds the C code for the X toolkit objects used by XEmacs.
|
|
0
|
143 `info' holds the Info documentation tree for XEmacs.
|
|
623
|
144 `man' holds the source code for the XEmacs online documentation.
|
|
|
145 `nt' holds files used compiling XEmacs under Microsoft Windows.
