[xemacs-hg @ 2003-03-02 02:18:05 by ben] To: xemacs-patches@xemacs.org PROBLEMS: Include nt/PROBLEMS and update. Add note about incremental linking badness. cmdloop.el, custom.el, dumped-lisp.el, files.el, keydefs.el, keymap.el, lisp-mode.el, make-docfile.el, replace.el, simple.el, subr.el, view-less.el, wid-edit.el: Lots of syncing with FSF 21.2. Use if-fboundp in wid-edit.el. New file newcomment.el from FSF. internals/internals.texi: Fix typo. (Build-Time Dependencies): New node. PROBLEMS: Delete. config.inc.samp, xemacs.mak: Eliminate HAVE_VC6, use SUPPORT_EDIT_AND_CONTINUE in its place. No incremental linking unless SUPPORT_EDIT_AND_CONTINUE, since it can cause nasty crashes in pdump. Put warnings about this in config.inc.samp. Report the full compile flags used for src and lib-src in the Installation output. alloc.c, lisp.h, ralloc.c, regex.c: Use ALLOCA() in regex.c to avoid excessive stack allocation. Also fix subtle problem with REL_ALLOC() -- any call to malloc() (direct or indirect) may relocate rel-alloced data, causing buffer text to shift. After any such call, regex must update all its pointers to such data. Add a system, when ERROR_CHECK_MALLOC, whereby regex.c indicates all the places it is prepared to handle malloc()/realloc()/free(), and any calls anywhere in XEmacs outside of this will trigger an abort. alloc.c, dialog-msw.c, eval.c, event-stream.c, general-slots.h, insdel.c, lisp.h, menubar-msw.c, menubar-x.c: Change *run_hook*_trapping_problems to take a warning class, not a string. Factor out code to issue warnings, add flag to call_trapping_problems() to postpone warning issue, and make *run_hook*_trapping_problems issue their own warnings tailored to the hook, postponed in the case of safe_run_hook_trapping_problems() so that the appropriate message can be issued about resetting to nil only when not `quit'. Make record_unwind_protect_restoring_int() non-static. dumper.c: Issue notes about incremental linking problems under Windows. fileio.c: Mule-ize encrypt/decrypt-string code. text.h: Spacing changes.

862 *** You type Control-H (Backspace) expecting to delete characters.
863
864 Emacs has traditionally used Control-H for help; unfortunately this
865 interferes with its use as Backspace on TTY's. As of XEmacs 21,
866 XEmacs looks at the "erase" setting of TTY structures and maps C-h to
867 backspace when erase is set to C-h. This is sort of a special hack,
868 but it makes it possible for you to use the standard:
869
870 stty erase ^H
871
872 to get your backspace key to erase characters. The erase setting is
873 recorded in the Lisp variable `tty-erase-char', which you can use to
874 tune the settings in your .emacs.
875
876 A major drawback of this is that when C-h becomes backspace, it no
877 longer invokes help. In that case, you need to use f1 for help, or
878 bind another key. An example of the latter is the following code,
879 which moves help to Meta-? (ESC ?):

1985 doc-strings, or cause other random problems.
1986
1987 You should remove these variables from your environment. These
1988 variables are not required to run FSF NTEmacs if you start it by
1989 running emacs.bat.
1990
1991 *** XEmacs can't find my init file
1992
1993 XEmacs looks for your init in your "home" directory -- either in
1994 `~/.xemacs/init.el' or `~/.emacs'. XEmacs decides that your "home"
1995 directory is, in order of preference:
1996
1997 - The value of the HOME environment variable, if the variable exists.
1998 - The value of the registry entry SOFTWARE\XEmacs\XEmacs\HOME,
1999 if it exists.
2000 - The value of the HOMEDRIVE and HOMEPATH environment variables, if
2001 these variables both exist.
2002 - C:\.
2003
2004 To determine what XEmacs thinks your home directory is, try opening
2005 a file in the `~' directory, and you should see its expansion in the
2006 modeline. If this doesn't work, type ESC : (user-home-directory).
2007
2008 *** XEmacs can't find any packages
2009
2010 XEmacs looks for your packages in subdirectories of a directory which
2011 is set at compile-time (see `config.inc'), and whose default is
2012 `C:\Program Files\XEmacs'. XEmacs also looks in `~/.xemacs', where
2013 `~' refers to your home directory (see previous entry). The variable
2014 `configure-package-path' holds the actual path that was compiled into
2015 your copy of XEmacs.
2016
2017 The compile-time default location can be overridden by the EMACSPACKAGEPATH
2018 environment variable or by the SOFTWARE\XEmacs\XEmacs\EMACSPACKAGEPATH
2019 registry entry. You should check that these variables, if they exist,
2020 point to the actual location of your package tree.
2021
2022 *** XEmacs doesn't die when shutting down Windows 95 or 98
2023
2024 When shutting down Windows 95 or 98 you may see a dialog that says
2025 "xemacs / You must quit this program before you quit Windows".
2026 It is safe to
2027 "Click OK to quit the program and Windows",
2028 but you won't be offered a chance to save any modified XEmacs buffers.
2029
2030 *** Key bindings
2031
2032 The C-z, C-x, C-c, and C-v keystrokes have traditional uses in both
2033 emacs and Windows programs. XEmacs binds these keys to their
2034 traditional emacs uses, and provides Windows 3.x style bindings for
2035 the Cut, Copy and Paste functions.
2036
2037 Function XEmacs binding
2038 -------- --------------
2039 Undo C-_
2040 Cut Sh-Del
2041 Copy C-Insert
2042 Paste Sh-Insert
2043
2044 You can rebind keys to make XEmacs more Windows-compatible; for
2045 example, to bind C-z to undo:
2046
2047 (global-set-key [(control z)] 'undo)
2048
2049 Rebindind C-x and C-c is trickier because by default these are prefix
2050 keys in XEmacs. See the "Key Bindings" node in the XEmacs manual.
2051
2052 *** Behavior of selected regions
2053
2054 Use the pending-del package to enable the standard Windows behavior of
2055 self-inserting deletes region.
2056
2057 *** Limitations on the use of the AltGr key.
2058
2059 In some locale and OS combinations you can't generate M-AltGr-key or
2060 C-M-AltGr-key sequences at all.
2061
2062 To generate C-AltGr-key or C-M-AltGr-key sequences you must use the
2063 right-hand Control key and you must press it *after* AltGr.
2064
2065 These limitations arise from fundamental problems in the way that the
2066 win32 API reports AltGr key events. There isn't anything that XEmacs
2067 can do to work round these problems that it isn't already doing.
2068
2069 You may want to create alternative bindings if any of the standard
2070 XEmacs bindings require you to use some combination of Control or Meta
2071 and AltGr.
2072

2075 Attempting to use call-process to run a 16bit program gives a
2076 "Spawning child process: Exec format error". For example shell-command
2077 fails under Windows 95 and 98 if you use command.com or any other
2078 16bit program as your shell.

2080 XEmacs may incorrectly quote your call-process command if it contains
2081 double quotes, backslashes or spaces.

2083 start-process and functions that rely on it are supported under Windows 95,
2084 98 and NT. However, starting a 16bit program that requires keyboard input
2085 may cause XEmacs to hang or crash under Windows 95 and 98, and will leave
2086 the orphaned 16bit program consuming all available CPU time.
2087
2088 Sending signals to subprocesses started by call-process or by
2089 start-process fails with a "Cannot send signal to process" error under
2090 Windows 95 and 98. As a side effect of this, quitting XEmacs while it
2091 is still running subprocesses causes it to crash under Windows 95 and
2092 98.
