[xemacs-hg @ 2004-12-05 08:48:12 by ben]
The section on Troubleshooting (now 2.3) has been completely written and
includes a lot of stuff that is not properly documented anywhere else. A
fair amount of obsolete info has been deleted and I've incorporated the
comments that people (mostly Stephen T) made. Former chapter 3 has been
split up in two, one pertaining to basic I/O and the other to external I/O.
What were formerly chapters 5 and 6 no longer exist as such; the info in
them has been distributed across various other chapters. Old chapter 4 got
split up, part going to the new chapter 4 on external I/O and part going to
the new chapter 5 on the Internet. In this new chapter, stuff not
pertaining to a specific package (e.g. VM or GNUS) was taken out of
package-specific sections and a general mail section was constituted. Part
of old chapter 5 remains in a new chapter 6 devoted to Emacs Lisp and other
advanced stuff, and a section from old chapter 3 on basic init-file Lisp
and some stuff from old chapter 5 on Info. The rest of chapter 5 was just
misc and has gotten scattered to the winds (mostly in chapters 3 and 4).
Old chapter 6 has also gotten quite scattered; there is no longer any
section specifically devoted to Windows except one of the Installation
sections (along with a section specfically devoted to Unix), and the rest
has moved to join the appropriate non-Windows-specific section elsewhere.
A lot of chapters had their sections rearranged and likewise for sections
having entries rearranged, with the intention that the new arrangement
should be more natural. In general I hope that stuff should be much easier
to locate. I also rewrote the entries on the relation between XEmacs and
GNU Emacs on the authors of XEmacs, including lots of info on who wrote
specific subsections. However, this history is certainly not complete; I
hope people will look over this and fix it up as necessary.

For a detailed description of the differences between GNU Emacs and XEmacs and a detailed history of XEmacs, check out the @@ -564,82 +684,322 @@ @uref{http://www.xemacs.org/About/XEmacsVsGNUemacs.html, NEWS file} @end example -However, here is a list of some of the reasons why we think you might -consider using it: +@table @strong +@item User-Visible Editing Features +XEmacs in general tries hard to conform to exist user-interface +standards, and to work "out-of-the-box" without the need for obscure +customization changes. GNU Emacs, particularly version 21, has gotten +better about this (in many cases by copying the XEmacs behavior!), but +still has some weirdnesses. For example, the standard method of +selecting text using the Shift key works out-of-the-box in XEmacs. + +XEmacs has a built-in toolbar. Four toolbars can actually be configured +simultaneously: top, bottom, left, and right toolbars. + +XEmacs has vertical and horizontal scrollbars. Unlike in GNU Emacs 19 +(which provides a primitive form of vertical scrollbar), these are true +toolkit scrollbars. A look-alike Motif scrollbar is provided for those +who don't have Motif. (Even for those who do, the look-alike may be +preferable as it is faster.) + +XEmacs has buffer tabs along the top of the frame (although the +position can be changed) that make it very easy to switch buffers. + +The menubar under XEmacs is better-designed, with more thought put into +it. + +XEmacs can ask questions using popup dialog boxes. Any command executed +from a menu will ask yes/no questions with dialog boxes, while commands +executed via the keyboard will use the minibuffer. + +XEmacs under MS Windows provides uses the standard file-dialog box for +opening and saving files. Standard menu-accelerator behavior can easily +be enabled using the Options menu, and integrates well into the existing +keymap. + +XEmacs has (still experimental) support for widgets of various sorts -- +buttons, text boxes, sliders, progress bars, etc. A progress bar is +used in font lock to show the progress. + +Experimental support for drag-and-drop protocols is provided from +XEmacs 21. + +@item General Platform Support +If you're running on a machine with audio hardware, you can specify +sound files for XEmacs to play instead of the default X beep. See the +documentation of the function load-sound-file and the variable +sound-alist. XEmacs also supports the network sound protocols NAS and +EsounD. + +XEmacs 21 supports database protocols with LISP bindings, currently +including Berkeley DB, LDAP, and PostgreSQL (21.2 only). + +XEmacs 20 and 21 support the Canna, Wnn, and SJ3 Japanese input method +servers directly, as well as through the X Input Method (XIM) +protocol. GNU Emacs 20 supports only the XIM protocol. Both Emacsen +support the Quail family of input methods (implemented in LISP) for many +languages. + +XEmacs provides support for ToolTalk on systems that have +it. + +@item Packaged LISP Libraries +Many more packages are provided standard with XEmacs than with GNU Emacs +19 or 20. + +XEmacs 21 supports an integrated package management system which uses +EFS to download, then automatically install prebuilt LISP +libraries. This allows XEmacs users much more straightforward access to +the "latest and greatest" version of any given library. + +We are working on a standard method for enabling, disabling and +otherwise controlling packages, which should make them very easy to use. + +@item LISP Programming +From XEmacs 20 on, characters are a separate type. Characters can be +converted to integers (and many integers can be converted to +characters), but characters are not integers. GNU Emacs 19, XEmacs 19, +Mule 2.3 (an extensive patch to GNU Emacs 18.55 and 19.x), and GNU Emacs +20 (incorporating Mule 3 and later Mule 4) represent them as integers. + +From XEmacs 20 on, the buffer is treated as an array of characters, and +the representation of buffer text is not exposed to LISP. The GNU Emacs +20 functions like buffer-as-multibyte are not supported. + +In XEmacs, events are first-class objects. GNU Emacs 19 represents them +as integers, which obscures the differences between a key gesture and +the ancient ASCII code used to represent a particular overlapping subset +of them. + +In XEmacs, keymaps are first-class opaque objects. GNU Emacs 19 +represents them as complicated combinations of association lists and +vectors. If you use the advertised functional interface to manipulation +of keymaps, the same code will work in XEmacs, GNU Emacs 18, and GNU +Emacs 19; if your code depends on the underlying implementation of +keymaps, it will not. + +XEmacs uses "extents" to represent all non-textual aspects of buffers; +GNU Emacs 19 uses two distinct objects, "text properties" and +"overlays", which divide up the functionality between them. Extents are +a superset of the union of the functionality of the two GNU Emacs data +types. The full GNU Emacs 19 interface to text properties and overlays +is supported in XEmacs (with extents being the underlying +representation). + +Extents can be made to be copied into strings, and then restored, by +kill and yank. Thus, one can specify this behavior on either "extents" +or "text properties", whereas in GNU Emacs 19 text properties always +have this behavior and overlays never do. + +@item Window System Programming Interface +XEmacs uses the MIT "Xt" toolkit instead of raw Xlib calls, which makes +it be a more well-behaved X citizen (and also improves portability). A +result of this is that it is possible to include other Xt "Widgets" in +the XEmacs window. Also, XEmacs understands the standard Xt command-line +arguments. + +XEmacs supports Motif applications, generic Xt (e.g. Athena) +applications, and raw Xlib applications. An XEmacs variant which +supports GTK+ is available (integration as an option in the XEmacs +mainline is planned for XEmacs 22), although code to take advantage of +the support is as yet scarce. + +An XEmacs frame can be placed within an "external client widget" managed +by another application. This allows an application to use an XEmacs +frame as its text pane rather than the standard Text widget that is +provided with Motif or Athena. + +@item Community Participation +Starting with XEmacs 20, joining the XEmacs development team is +simple. Mail to @email{xemacs-beta@@xemacs.org, XEmacs Developers}, and +you're in! (If you want to be, of course. You're also welcome to just +post development-related questions and bug reports.) The GNU Emacs +development team and internal mailing lists are still by invitation +only. + +The "bleeding edge" of mainline XEmacs development is available by +anonymous CVS as are some subsidiary branches (check out the xemacs-gtk +module for the latest in GUI features!) + +Development and maintenance of Lisp libraries is separated from the core +editor development at a fairly low level. This provides better +modularization and a better division of responsibility between external +library maintainers and the XEmacs core development team. Even for +packages the size of Gnus, XEmacs users normally have access to a +pre-built version within a few weeks of a major release, and minor +updates often within days. + +CVS commit authority is broadly dispersed. Recognized maintainers of +LISP libraries who are willing to maintain XEmacs packaged versions +automatically qualify for CVS accounts for their packages. +@end table + +@node Q1.0.6, Q1.0.7, Q1.0.5, Introduction +@unnumberedsubsec Q1.0.6: How much does XEmacs differ? + +RMS has asserted at times that XEmacs is merely a "patch" on top of +GNU Emacs (@pxref{Q1.0.7}). In fact, probably not more than 5% of the +code, if that, remains unchanged, and nearly 14 years of work has gone +into XEmacs at this point. (GNU Emacs itself is only than 20 years +old, and thus XEmacs has existed as a separate product for over 2/3 of +the lifespan of GNU Emacs.) As a point of comparison, XEmacs 21.5 has +perhaps 65,000 more lines of C code than GNU Emacs 21.2. + +However, the XEmacs developers strive to keep their code compatible with +GNU Emacs, especially on the Lisp level. Much effort goes into +"synching" the XEmacs Elisp code with recent GNU Emacs releases so as to +benefit from GNU Emacs development work. (In contrast, almost no code +from XEmacs has made it into GNU Emacs, and in fact the GNU Emacs +developers are instructed by RMS not to even look at XEmacs source code! +This stems from self-imposed licensing restrictions on the part of GNU +Emacs -- and almost certainly out of hostility, as well.) + +@node Q1.0.7, Q1.0.8, Q1.0.6, Introduction +@unnumberedsubsec Q1.0.7: Is XEmacs "GNU"? + +RMS insists on the term "GNU XEmacs" and maintains that + +@quotation +XEmacs is GNU software because it's a modified version of a +GNU program. And it is GNU software because the FSF is the copyright +holder for most of it, and therefore the legal responsibility for +protecting its free status falls on us whether we want it or not. This +is why the term "GNU XEmacs" is legitimate. +@end quotation + +In fact, FSF is @emph{not} the copyright holder for most of the code, +as very little unmodified FSF code remains (@pxref{Q1.0.6}). + +Furthermore, RMS's assertion that XEmacs is "GNU" seems rather bizarre +to the XEmacs developers given RMS's hostility and general lack of +interest in cooperation. "GNU" software in general is part of the GNU +Project, is distributed by it on their FTP site, and receives support +(or at least cooperation), as well as implicit endorsement, from it. +The GNU Project, however, has never supported XEmacs and never +distributed XEmacs, and RMS's hostility is the farthest thing possible +from an endorsement. In fact, the GNU Project distributes a number of +non-GNU software projects on the FSF web site, but again XEmacs is not +one of them. + +@node Q1.0.8, Q1.0.9, Q1.0.7, Introduction +@unnumberedsubsec Q1.0.8: What is the correct way to refer to XEmacs and GNU Emacs? + +Unfortunately even the naming of these two applications has become +politicized. Much of this stems from RMS, who has a history of +politicizing similar issues. (Compare the controversy over "Lignux" +and "GNU/Linux".) We would prefer that the terms "XEmacs" and "GNU +Emacs" be used, which are neutral and acceptable to most people. RMS, +however, is not willing to accept these terms. He insists that, if +his product is called "GNU Emacs", then ours must be called "GNU +XEmacs". (For our opinion of this term, @xref{Q1.0.7}.) On the other +hand, if our product is to be called "XEmacs", as we prefer, then his +product must simply be called "Emacs". The intent of this seems +clear: RMS wants to make sure the names reflect his view that his +version is the "real" Emacs and ours is merely a derivative, +second-class product (@pxref{Q1.0.6}). + +The XEmacs developers hope that you will use the neutral terms +"XEmacs" and "GNU Emacs" for these two specific products. "Emacs", on +the other hand, is a generic term for a class of programmable text +editors with a similar look-and-feel, and usually a Lisp-based +extension language. These trace themselves back to early editors such +as EINE, ZWEI, ZMACS and Multics Emacs. @xref{A History of Emacs,,, +internals, XEmacs Internals Manual}. + +We also call upon RMS, in the spirit of furthering cooperation, to +stop politicizing this issue and use the neutral terms "XEmacs" and +"GNU Emacs". We have already acceded to RMS' wishes in this respect, +and we expect him to do the same. (In the past, the XEmacs developers +often used the terms "FSF Emacs" or "FSFmacs" or "RMSmacs" in +reference to GNU Emacs; these terms were apparently modeled after RMS' +own usage of "Gosmacs" and "Gosling Emacs" in reference to Unipress +Emacs, produced by James Gosling. RMS, however, considers such terms +to be insulting, so we refrain from using them as much as possible in +preference to GNU Emacs.) + +@node Q1.0.9, Q1.0.10, Q1.0.8, Introduction +@unnumberedsubsec Q1.0.9: Why haven't XEmacs and GNU Emacs merged? + +There are currently irreconcilable differences in the views about +technical, programming, design, organizational and legal matters +between Richard Stallman (RMS), the author and leader of the GNU Emacs +project, and the XEmacs development team which provide little hope for +a merge to take place in the short-term future. There have been +repeated attempts at merging by all of the major XEmacs developers, +starting from the early days of Lucid Emacs (in 1991), but they have +all failed. RMS has very strong views about how GNU Emacs should be +structured and how his project should be run, and during the repeated +merge efforts has never demonstrated any realistic interest in +sufficiently compromising or ceding control to allow a middle ground +to be found. The basic problem seems to be the very different goals +of RMS and the XEmacs project. The primary goals of the XEmacs +project are technical and organizational -- we want to create the best +editor possible, and to make it as easy as possible for people around +the world to contribute. The primary goals of RMS, on the other hand, +are political, and GNU Emacs, and any potential merge efforts with +XEmacs, are strictly subservient to these goals. In fact, in many +ways RMS sees GNU Emacs as the "poster child" of his aims, the one +program in the GNU project that above all others must set an example +to the world. (This has to do with the fact that GNU Emacs was the +first program in the GNU project, and the only one that he is still +personally involved with on a day-to-day basis.) Given his goals, his +position is completely reasonable -- but unfortunately, makes any +merge impossible. + +From the XEmacs perspective, the most intractable issues appear to be +legal and organizational, specifically: @itemize @bullet @item -It looks nicer. - -@item -The XEmacs maintainers are generally more receptive to suggestions than -the GNU Emacs maintainers. - -@item -Many more bundled packages than GNU Emacs. - -@item -Binaries are available for many common operating systems. - -@item -Face support on TTY's. - -@item -A built-in toolbar. - -@item -Better Motif compliance. - -@item -Some internationalization support (including full MULE support, if -compiled with it). - -@item -Variable-width fonts. - -@item -Variable-height lines. - -@item -Marginal annotations. - -@item -ToolTalk support. - -@item -XEmacs can be used as an Xt widget, and can be embedded within another -application. - -@item -Horizontal and vertical scrollbars (using real toolkit scrollbars). - -@item -Better APIs (and performance) for attaching fonts, colors, and other -properties to text. - -@item -The ability to embed arbitrary graphics in a buffer. - -@item -Completely compatible (at the C level) with the Xt-based toolkits. - +RMS requires "legal papers" to be signed for all contributions of code +to GNU Emacs over 10 lines or so, transferring the copyright and all +legal rights to the code to the Free Software Foundation. XEmacs does +not and has never required this, since it has the practical effect of +discouraging individual and in particular corporate contributions -- +corporations will almost never sign away their legal rights to code +since it makes it impossible to reuse the code in any product that +whose license is not compatible with the GNU General Public License. +Since RMS has shown no inclination to compromise on this issue, a +merge would require that most of the existing XEmacs code would need +to be thrown away and rewritten -- something the XEmacs developers are +understandably reluctant to do. + +@item +A repeated stumbling block in the merge talks has been the issue of +organizational control over the resulting product. RMS has made it +clear that he intends to have final say over design issues in a merged +Emacs. Unfortunately, RMS and the XEmacs developers have repeatedly +clashed over design decisions, and RMS' insistence on getting his way +in such disagreements was the very reason for the split in the first +place. This same issue has come up again and again in merge talks and +we have never been able to come to a satisfactory resolution. To the +extent that RMS is willing to compromise at all, it appears to be of a +purely political rather than technical nature -- "If we support this +feature of yours, we also get to support this other feature of mine." +The XEmacs developers cannot see how such a process would lead to +anything but a mess of incompatible things hodgepodged together. + +@item +Because of the years of separate development, distinct and +incompatible interfaces have developed and merging would be extremely +difficult even with the above non-technical issues resolved. The +problem has been exacerbated by the issue of legal papers -- because +XEmacs code is not "kosher" from RMS' perspective, he discourages +developers from even looking at it out of legal concerns. Although it +is still possible to read the XEmacs documentation and run the +program, the practical effect of this prohibition has been to strongly +discourage code-sharing and cooperative development -- although a +great deal of GNU Emacs code has been incorporated into XEmacs, +practically none has gone the other direction. @end itemize -@node Q1.0.5, Q1.0.6, Q1.0.4, Introduction -@unnumberedsubsec Q1.0.5: Why Haven't XEmacs and GNU Emacs Merged? - -There are currently irreconcilable differences in the views about -technical, programming, design and organizational matters between RMS -and the XEmacs development team which provide little hope for a merge to -take place in the short-term future. - If you have a comment to add regarding the merge, it is a good idea to -avoid posting to the newsgroups, because of the very heated flamewars -that often result.

Beginning with release 21.0, XEmacs has worked under MS Windows +and is fully-featured and actively developed. A group of dedicated +developers actively maintains and improves the Windows-specific +portions of the code. Some of the core developers, in fact, use +Windows as their only development environment, and some features, such +as printing, actually work better on Windows than native Unix and Mac +OS X. The mailing list at @email{xemacs-winnt@@xemacs.org} is dedicated +to that effort (please use the -request address to +subscribe). (Despite its name, XEmacs actually works on all versions +of Windows.) + +The list name is misleading, as XEmacs supports and has been compiled on +Windows 95, Windows 98, Windows NT, Windows 2000, Windows ME, Windows +XP, and all newer versions of Windows. The MS Windows-specific code is +based on Microsoft Win32 API, and will not work on MS Windows 3.x or on +MS-DOS. + +XEmacs also supports the Cygwin and MinGW development and runtime +environments, where it also uses native Windows code for graphical +features. In addition, under Cygwin it is possible to compile XEmacs +to use an X server (and XFree86 is available as part of the standard +Cygwin installation). + +@node Q1.1.3, Q1.1.4, Q1.1.2, Introduction +@unnumberedsubsec Q1.1.3: Can I build XEmacs on MS Windows with X support?

But if you have them and +want to use them, XEmacs supports these environments. + +(One important reason to support Cygwin is that it lets the MS Windows +developers test out their code in a Unix environment without actually +having to have a Unix machine around. For this reason alone, Cygwin +support is likely to remain supported for a long time in XEmacs. Same +goes for the X support under Cygwin, for the same reasons. MinGW +support, on the other hand, depends on volunteers to keep it up to date; +but this is generally not hard.) + +Cygwin is a set of tools providing Unix-like API on top of Win32. +It makes it easy to port large Unix programs without significant +changes to their source code. It is a development environment as well +as a runtime environment. + +When built with Cygwin, XEmacs supports all display types -- TTY, X & +Win32 GUI, and can be built with support for all three simultaneously. +If you build with Win32 GUI support then the Cygwin version uses the +majority of the Windows-specific code, which is mostly related to +display. If you want to build with X support you need X libraries (and +an X server to display XEmacs on); see @ref{Q2.2.7}. TTY and Win32 GUI +require no additional libraries beyond what comes standard with Cygwin. + +The advantages of the Cygwin version are that it integrates well with +the Cygwin environment for existing Cygwin users; uses configure so +building with different features is very easy; and actively supports X & +TTY. Furthermore, the entire Cygwin environment and compiler are free, +whereas Visual C++ costs money. + +The disadvantage is that it requires the whole Cygwin environment, +whereas the native port requires only a suitable MS Windows compiler. +Also, it follows the Unix filesystem and process model very closely +(some will undoubtedly view this as an advantage). + +See @uref{http://sources.redhat.com/cygwin/} for more information on +Cygwin. + +MinGW is a collection of header files and import libraries that allow +one to use GCC under the Cygwin environment to compile and produce +exactly the same native Win32 programs that you can using Visual C++. +Programs compiled with MinGW make use of the standard Microsoft runtime +library @file{MSVCRT.DLL}, present on all Windows systems, and look, +feel, and act like a standard Visual-C-produced application. (The only +difference is the compiler.) This means that, unlike a +standardly-compiled Cygwin application, no extra runtime support +(e.g. Cygwin's @file{cygwin1.dll}) is required. This, along with the +fact that GCC is free (and works in a nice Unix-y way in a nice Unix-y +environment, for those die-hard Unix hackers out there), is the main +advantage of MinGW. It is also potentially faster than Cygwin because +it has less overhead when calling Windows, but you lose the POSIX +emulation layer, which makes Unix programs harder to port.

Has that been fixed? + +Yes. + +The console was there because @file{temacs} (and in turn, @file{xemacs}) +was a console application, and Windows typically creates a new +console for a console process unless the creating process requests that +one isn't created. This used to be fixed with @file{runemacs}, a small +Windows application that existed merely to start @file{xemacs}, stating +that it didn't want a console. + +XEmacs 21.4 fixes this cleanly by the virtue of being a true "GUI" +application. The explanation of what that means is included for +educational value. + +When building an application to be run in a Win32 environment, you must +state which sub-system it is to run in. Valid subsystems include +"console" and "gui". The subsystem you use affects the run time +libraries linked into your application, the start up function that is +run before control is handed over to your application, the entry point +to your program, and how Windows normally invokes your program. (Console +programs automatically get a console created for them at startup if +their stdin/stdout don't point anywhere useful, which is the case when +run from the GUI. This is a stupid design, of course -- instead, the +console should get created only when the first I/O actually occurs! +GUI programs have an equally stupid design: When called from +@file{CMD.EXE}/@file{COMMAND.COM}, their stdin/stdout will be set to +point nowhere useful, even though the command shell has its own +stdin/stdout. It's as if someone who had learned a bit about stdio but +had no actual knowledge of interprocess communication designed the +scheme; unfortunately, the whole process-communication aspect of the +Win32 API is equally badly designed.) For example, the entry point for a +console app is "main" (which is what you'd expect for a C/C++ program), +but the entry point for a "gui" app is "WinMain". This confuses and +annoys a lot of programmers who've grown up on Unix systems, where the +kernel doesn't really care whether your application is a gui program or +not. + +For reasons not altogether clear, and are lost in the mists of time and +tradition, XEmacs on Win32 started out as a console application, and +therefore a console was automatically created for it. (It may have been +made a console application partly because a console is needed in some +circumstances, especially under Win95, to interrupt, terminate, or send +signals to a child process, and because of the bogosity mentioned above +with GUI programs and the standard command shell. Currently, XEmacs +just creates and immediately hides a console when necessary, and +works around the "no useful stdio" problem by creating its own console +window as necessary to display messages in.) + +@node Display Subsystems, External Subsystems, Installation, Top +@unnumbered 3 Basic Display-Related Subsystems + +This is part 3 of the XEmacs Frequently Asked Questions list.

But if you have them and -want to use them, XEmacs supports these environments. - -(One important reason to support Cygwin is that it lets the MS Windows -developers test out their code in a Unix environment without actually -having to have a Unix machine around.

MinGW -support, on the other hand, depends on volunteers to keep it up to date; -but this is generally not hard.) - -Cygwin is a set of tools providing Unix-like API on top of Win32. -It makes it easy to port large Unix programs without significant -changes to their source code. It is a development environment as well -as a runtime environment. - -When built with Cygwin, XEmacs supports all display types -- TTY, X & -Win32 GUI, and can be built with support for all three simultaneously. -If you build with Win32 GUI support then the Cygwin version uses the -majority of the Windows-specific code, which is mostly related to -display. If you want to build with X support you need X libraries (and -an X server to display XEmacs on); see @ref{Q6.1.4}.
