=============================================================================== GNU Emacs 19 for emx (OS/2 2.0 and 2.1) 26-Jul-1993 =============================================================================== Introduction ============ This is GNU Emacs 19.17 for emx on OS/2 2.0 or 2.1. The port was done by Eberhard Mattes based on ideas of the port of GNU Emacs for OS/2 done by Joerg Viola. There is a slight chance that this port of GNU Emacs also works with emx on MS-DOS, but that hasn't been tested. Distribution files ================== The "GNU Emacs 19.17 for emx" distribution consists of the following files: README this file (/emacs/19.17/emx/README) e17el1.zip Emacs Lisp files (source), part 1 e17el2.zip Emacs Lisp files (source), part 2 e17info.zip info files (on-line help) e17lib1.zip Emacs Lisp library (base set, compiled) e17lib2.zip Emacs Lisp library (remaining files, compiled) e17man.zip documentation files (mostly for TeX) e17min.zip minimal set of files for running GNU Emacs e17more.zip additional files e17rest.zip remaining files e17src.zip sources Other files of interest ======================= GNU Emacs 19.17 for emx requires emx 0.8g -- if you have an older version of emx.dll, emxbind.exe and termcap.dat, get emxrt.zip from ftp.uni-stuttgart.de [129.69.1.12]: /soft/os2/emx-0.8g ftp-os2.nmsu.edu [128.123.35.151]: /os2/2_x/unix/gnu/emx08g src.doc.ic.ac.uk [146.169.2.1]: /pub/packages/os2/2_x/unix/gnu/emx08g ftp.informatik.tu-muenchen.de [131.159.0.198]: /pub/comp/os/os2/devtools/emx+gcc You might want to also get the following files: ftp-os2.nmsu.edu: os2/all/graphics/smallfnt.zip ftp-os2.nmsu.edu: os2/all/unix/shells/ms_sh21c.zip ftp-os2.nmsu.edu: os2/2_x/unix/unixutils/isp3009b.zip ftp.informatik.tu-muenchen.de: pub/comp/os/os2/gnu/systools/gnufutil.zip prep.ai.mit.edu: pub/gnu/elisp-2.01.1.tar.gz smallfnt.zip contains a small fixed-width bitmapped font for the Presentation Manager. ms_sh21c.zip contains the Data Logic shell, a Unix-like shell. isp3009b.zip contains Ispell, a spelling checker, which can be used with GNU Emacs. gnufutil.zip contains the GNU file utilities. ls.exe is required for dired and for recover-file. elisp-2.01.1.tar.gz contains the Emacs Lisp documentation. Installing the emx runtime package ================================== Install the emx runtime package emxrt.zip (version 0.8g or later) if not already installed. First, unpack the files of the emx runtime package to your hard disk: cd \ unzip a:emxrt Installation of the emx runtime package involves changing the LIBPATH statement of your config.sys file and setting the following environment variables in config.sys: TERMCAP name of termcap file, defaults to /emx/etc/termcap.dat TERM name of the terminal, possible values include rmono, ansi-color-2 and ansi-color-3 PATH include \emx\bin in your PATH Example (the emx runtime package is installed on drive C): LIBPATH=C:\OS2\DLL;[...];c:\emx\dll SET PATH=C:\OS2;C:\OS2\SYSTEM;[...];c:\emx\bin SET TERMCAP=c:/emx/etc/termcap.dat SET TERM=ansi-color-3 See \emx\doc\emxrt.doc and \emx\book\emxrt.inf for details on installing the emx runtime package. Installing GNU Emacs ==================== This section describes how to install the compiled version of GNU Emacs 19.17 for emx on OS/2 2.0 and 2.1. GNU Emacs is installed in the \emacs directory of a HPFS drive. 1. Get lots of disk space on an HPFS partition. As this version of GNU Emacs doesn't bother about 8.3 file names, you can't install it on a FAT partition. (Well, probably you can, but it has not been tested.) However, you can edit files on FAT partitions. 2. Set appropriate environment variables (set them in config.sys): SHELL name of the command processor, defaults to /bin/sh. If you have a Unix-like shell (such as the Data Logic shell), you should use the path name of that shell. Otherwise, use the path name of cmd.exe EMACSLOADPATH path to Lisp library, defaults to /emacs/19.17/lisp EMACSPATH path to programs, defaults to /emacs/19.17/bin SYSTEMNAME initializes system-name, the name of the machine. The default value is "my-system" HOME your home path, replaces ~ in path names. Emacs tries to load .emacs, for instance, from that directory TMP directory for temporary files. The default is the current working directory Example (Emacs will be installed on drive C): SET PATH=C:\OS2;[...];C:\EMACS\19.17\BIN SET SHELL=c:/bin/sh.exe SET EMACSLOADPATH=c:/emacs/19.17/lisp SET EMACSPATH=c:/emacs/19.17/bin SET SYSTEMNAME=vergil SET HOME=c:/home SET TMP=c:/tmp 3. Reboot your computer to activate the new config.sys settings. 4. To install a minimal version of GNU Emacs, change to the target drive and unpack the file e17min.zip by typing cd \ unzip a:e17min on an HPFS drive. Note that you cannot use PKUNZIP to unpack the ZIP files. 5. Create a preloaded version of GNU Emacs by typing cd \emacs\19.17\bin dump In case you're short of disk space, you can delete the file \emacs\19.17\bin\temacs now. If you want to dump Emacs again, restore that file from e17min.zip. 6. Now you can run GNU Emacs by typing emacs (run Emacs in text mode) emacs -d (run Emacs in PM mode) 7. The minimal version of GNU Emacs installed now is hardly usable. For instance, there is no on-line help. You should install additional files: cd \ unzip a:e17lib1 unzip a:e17more unzip a:e17info 8. To unpack all the .el files, type cd \ unzip a:e17el1 unzip a:e17el2 For running GNU Emacs, only the compiled (.elc) files are required. You need the .el files if you need documentation about the various Emacs Lisp packages or want to change them. Additional files are packaged in the remaining ZIP files: cd \ unzip a:e17lib2 unzip a:e17rest unzip a:e17man These files are usually not required for running GNU Emacs under emx. 9. You might want to add program objects for the programs c:\emacs\19.17\bin\emacs.exe c:\emacs\19.17\bin\emacsclient.exe to an appropriate folder. There is a REXX program called instemacs.cmd to do this for you. Type instemacs to get a list of options. To simply create the program objects, type instemacs install This creates a folder called "New Things" on your desktop which contains the new objects. If you would like to create a shadow of Emacs in your startup folder, you can additionally use the "startup" option. To automatically associate Emacsclient with plain text files, use the "associate" option. instemacs.cmd will copy the current associatations of the OS/2 System Editor for Emacsclient. For Emacsclient to work, an instance of Emacs must be running and the server must be active. You will probably want to put the line (server-start) in your site-start.el file (see below) and use the "startup" option. In a standard OS/2 installation, the OS/2 System Editor is automatically associated with text files so that double clicking a text file opens the System Editor. You can specify the "makedefault" option when calling instemacs.cmd to make Emacsclient the default "view" for text files. NOTE: The "makedefault" option of instemacs.cmd manipulates the Workplace Shell associations in an undocumented way by directly accessing certain values in OS2.INI. This has only been tested under OS/2 2.1 GA (US version). There is no guarantee that this will work on any other version of OS/2. But then there is no guarantee that any of the programs in this package will work at all, anyway :-). Note that instemacs.cmd creates the program objects in such a way that emacs.exe is started as a Presentation Manager program, although it is actually a text mode program. This is because emacs.exe actually calls pmemacs.exe to provide the PM interface. If emacs.exe were started as a text mode program, it would have its own VIO window, which is usually useless. Starting emacs.exe as a PM program has two known disadvantages: (a) You don't see the standard output of emacs.exe. If Emacs crashes for any reason, you won't see any diagnostics or error messages and you can't tell Emacs to auto-save (if it happens to ask). (b) If you double click on the Emacs object when Emacs is already running, you will not bring the Emacs window to the foreground but something else, usually the Window List. Double clicking on Emacs in the Window List works, of course. If you feel you would like a more conventional program object for Emacs, you can use the "keepvio" option of instemacs.cmd. This causes the Emacs object to start emacs.exe in a minimized VIO window. This solves problem (a) and changes problem (b) to the problem (b') that double clicking on the Emacs object shows the VIO window of emacs.exe, not the PM Window you are really interested in. If all this sounds too complicated to you, simply try instemacs.cmd with and without the "keepvio" option and see which way you like it better. Calling instemacs.cmd again does not create new objects but updates the existing objects according to the options. You can also use this feature if you accidentally change the settings of the Emacs object or lose the icon. Customizing GNU Emacs ===================== You should customize \emacs\19.17\lisp\site-start.el, the startup file of GNU Emacs. The statements in that file are executed automatically each time GNU Emacs is started. Moreover, you can put personal settings into a file named .emacs file in your home directory (set by the HOME environment variable). Sample site-start.el file: --------------------------------------------------------------------- (set-input-mode nil nil 1) ; [1] (setq default-frame-alist ; [2] (append default-frame-alist '((altgr-modifier . meta)))) (standard-display-8bit 128 254) ; [3] (aset standard-display-table 256 16) ; [4] (aset standard-display-table 257 31) (aset standard-display-table 259 24) (add-hook 'server-request-hook ; [5] '(lambda () (make-frame-visible) (focus-frame (selected-frame)))) (add-hook 'dired-load-hook 'emx-dired-kur-ls-setup) ; [6] (autoload 'os2help "os2help" "OS/2 on-line help" t) ; [7] (setq os2help "/emx/book/emxdoc.ndx") (global-set-key [C-f1] 'os2help) (if window-system (progn (pm-edit-menu) ; [8] (set-face-background 'modeline "red") ; [9] (set-face-foreground 'modeline "yellow"))) --------------------------------------------------------------------- Notes: [1] Enable 8-bit input. set-input-mode must be called when running Emacs -- calling it before dumping doesn't work [2] Use the right ALT key of non-US keyboards as META key. This does not work for all key combinations. Note that the right ALT key of US keyboards is equivalent to the left ALT key. Add new parameters to the front of the list [3] Display characters 128 through 254 as-is. Without this statement, octal notation is used for these characters [4] Use special symbols (which are not displayed as-is when occurring in a buffer) for truncated screen lines (256), continued lines (257) and for displaying control characters notation (259) [5] Raise frame to the foreground if emacsclient requests a buffer [6] Use Kai Uwe Rommel's OS/2 port of GNU ls (GNU file utilities) for dired. If you're using a version of ls where the output of `ls -l' is Unix-compatible, you should not use that line [7] Use C-f1 to invoke OS/2 on-line help. You have to set the os2help variable to point to an EPM index file. See os2help.el for details [8] Modify the Edit menu of the menu bar to use the OS/2 clipboard for Cut, Copy and Paste [9] Make the mode line yellow on red About file names ================ All file names are translated to lower case. This is required as GNU Emacs thinks that non-equality of file names implies non-identity of files. Under OS/2 and DOS, however, letter case does not matter in file names. To keep the letter case in file names on HPFS, see `Choosing the backup type'. Better use forward slashes (/) instead of backslashes (\) in path names as some places where Emacs checks for / might have slipped my attention. Emacs doesn't know that trailing dots in file names are ignored by OS/2. It believes that "foo" and "foo." are different files. Choosing a PM font ================== A font is specified by size (printer's points), appearance (bold or italic, optional) and name: SIZE[.bold][.italic]NAME Note that not all fonts are available in all appearances. "System Monospaced", for instance, is available only in bold. Alternatively, you can use the "Host Portable Character Representation" for font names, for instance -os2-Courier-medium-r-normal--*-100-*-*-m-*-cp850 Examples of fixed-spaced bitmap fonts: 8.Courier 10.Courier 10.System Monospaced 12.bold.Courier 8.System VIO (OS/2 2.1) 6.Small (smallfnt, see below) As the plain, bold and italic variations of the PM fonts have different character widths, mixing fonts in a frame isn't a good idea. The character widths of all fonts are forced to the character width of the default font. When defining a face with a font which is wider than the default font, there will be problems: some characters will be displayed only partially and some pixels will stay on the screen until the frame is redisplayed (C-l). Fonts which are smaller than the default font, however, can be used. For instance, you can use "8.bold.System Monospaced" as bold font when using "10.Courier" as default font ("10.bold.Courier" is too wide). Using italic fonts is not recommended. The smallest fixed-width VGA bitmap font of OS/2 2.0 ("8.Courier") is rather big. A small font ("6.Small") is available for anonymous ftp: ftp-os2.nmsu.edu: os2/all/graphics/smallfnt.zip Using outline fonts (such as "9.Courier") is not recommended because that's too slow. Proportional fonts (such as "10.Tms Rmn") cannot be used. To set the default font of a frame, set the `font' frame parameter. Example: (setq default-frame-alist (append default-frame-alist '((font . "8.Courier")))) If the font does not exist, "10.Courier" is used instead as default font. If you use the "Host Portable Character Representation" for the name of the default font, Emacs automatically chooses bold and italic variants of that font. Example: (setq default-frame-alist (append default-frame-alist '((font . "-os2-Courier-medium-r-normal--*-100-*-*-m-*-cp850")))) You can use a popup menu to select the default font: Click mouse button 3 (that's the middle mouse button, by default) while depressing the CONTROL key (C-down-mouse-3). To change the font of a face, use set-face-font. However, you can use only fonts reported by the pm-list-fonts function. Examples: (set-face-font 'bold "10.bold.Courier") (set-face-font 'italic "10.italic.Courier") ; NOT RECOMMENDED! The keyboard ============ In text mode, the ALT keys generate the A- modifier (alt). The rest of this section applies to PM mode. The modifiers generated by the ALT keys are configurable. There are two ALT keys, the left ALT key and the right ALT key. The right ALT key is called AltGr or AltCar on most non-US keyboards. On these keyboards, the right ALT key is used for entering special symbols. On the US keyboard, the right ALT key is equivalent to the left ALT key. We'll use the term `ALT key' for both ALT keys of the US keyboard. For keyboards which have an AltGr or AltCar key, we'll call the left ALT key `ALT key' and the right ALT key `ALTGR key'. The modifier for the ALT key (both ALT keys on the US keyboard, that is) is set with the `alt-modifier' frame parameter. For instance, use the following code to use the ALT key for generating the A- (alt) modifier: (setq default-frame-alist (append default-frame-alist '((alt-modifier . alt)))) By default, the ALT key is used for generating the M- (meta) modifier. The modifier for the ALTGR key (which isn't present on the US keyboard) is set with the `altgr-modifier' frame parameter. For instance, use the following code to use the ALTGR key for generating the A- (alt) modifier: (setq default-frame-alist (append default-frame-alist '((altgr-modifier . alt)))) As ALTGR is treated specially by the operating system, you cannot use it with arbitrary keys. Usually you can use it together with a subset of the letter and digit keys to generate the modifier set with altgr-modifier. If the CTRL key is down, ALTGR is ignored for most keys. Suppose that '((alt-modifier . meta) (altgr-modifier . hyper)) is in effect. Then, you'll get the following table of keys vs. events: Left ALT | Right ALT | CTRL | Key || US keyboard | German keyboard ---------+-----------+------+-----++-------------+----------------- X | - | - | a || M-a | M-a X | - | X | a || M-C-a | M-C-a - | X | - | a || M-a | H-a - | X | X | a || M-C-a | C-a - | X | - | f2 || M-f2 | f2 - | X | - | q || M-q | @ - | X | - | q || M-C-q | C-@ The locations of the keys C-[ C-] C-\ etc. on non-US keyboards depend on whether you're using the PM version or the text mode version of Emacs: With the PM version, you can type those keys with CTRL+ALTGR+ (example: C-] is on CTRL+ALTGR+<9> of the German keyboard), where ALTGR is the right ALT key. With the text mode version, pretend that you have a US keyboard (example: C-] is on CTRL+<+> of the German keyboard). If you want to bind keys depending on the keyboard layout, use the keyboard-type function. Changing the window size ======================== To change the window size in text mode, type mode co80,x where x is the number of lines. Example: mode co80,40 To change the window size in PM mode, simply resize the window using the mouse or the keyboard (Alt+F8). You can set the default size with the `width' and `height' frame parameters in site-init.el or .emacs: (setq default-frame-alist (append default-frame-alist '((width . 80) (height . 40)))) You can set the default position with the `top' and `left' frame parameters. See the documentation of set-frame-position for details. Choosing the backup type ======================== You might want to use (setq backup-by-copying t) This has three advantages under OS/2: - the letter case of the name of the file is retained (normally, GNU Emacs for OS/2 2.0 uses lower-case file names) - the extended attributes of the file are retained - when editing .CMD files, the Workplace Shell does not change program objects to point to the backup of the edited file There are two known disadvantages under OS/2: - the extended attributes of the backup file are lost - the letter case of the file name is lost for the backup file You can choose: Either keep the extended attributes and the letter case of the file name of the new file or of the backup file. Text mode vs. binary mode ========================= This port of GNU Emacs supports two types of files: binary files and text files. As GNU Emacs is a text editor, you'll work with text files most of the time. Therefore, you don't have to know the ugly details unless you want to edit a binary file. When reading a text file, each CR/LF pair is converted to a LF. If the last character of the file is a Ctrl-Z, that character is removed. When writing a text file, each LF is replaced with a CR/LF pair. A Ctrl-Z is not appended as that has been obsolete for years. No conversion is done when reading or writing a binary file. The variable emx-binary-mode controls whether to use text mode or binary mode. If the variable is nil (that's the default setting), text mode is used. If the variable is t, binary mode is used. A file name hook is employed to temporarily set the emx-binary-mode variable depending on the file name while reading or writing a file. The emx-add-binary-mode function is used to define an additional regular expression for files which should be read and written in binary mode. Example: (emx-add-binary-mode "\\.exe$") This example will make Emacs use binary mode for file names ending with .exe. Initially, binary mode is used for file names matching the following regular expressions: \.elc$ \.tar$ Currently, there is no buffer-local variable for controlling text mode vs. binary mode. Do not set the emx-binary-mode variable manually -- always use emx-add-binary-mode. Code pages ========== cp850.el, which is loaded by default, defines a syntax table and a case table for code page 850. Using shell mode ================ GNU Emacs uses the shell (command processor) pointed to by the SHELL environment variable. I recommend using a Unix-like shell, like the Data Logic shell, which is available for anonymous ftp: ftp-os2.nmsu.edu: os2/all/unix/shells/ms_sh21c.zip To run an OS/2 command prompt (using cmd.exe as shell) in an Emacs window, use the cmd command defined in emx-cmd.el. Using the clipboard =================== To use the OS/2 clipboard, the following functions are provided: Function | Default key | Description ---------+-------------+--------------------------------------- pm-copy | C-insert | Copy the region to the clipboard pm-cut | S-delete | Copy the region to the clipboard, | | then delete the region pm-paste | S-insert | Paste text from the clipboard at point Note that several OS/2 programs cannot handle more than 64KB of text in the clipboard. Therefore you should avoid copying more than 64KB of text. You can let the Cut, Copy and Paste choices of the Edit menu of the menu bar use the clipboard. This is done by calling the pm-edit-menu function, as done by the default site-init.el file. If you want the original Edit menu, remove the invocation of pm-edit-menu from site-init.el. Using emacsclient ================= emacsclient has two new command line options: -s Don't switch the focus back to emacsclient when saying "Done" for a buffer (C-x #). This option is ignored if -w is used -w Don't wait for saying "Done" (C-x #) When using emacsclient as default OS/2 editor (by associating it with various file types as explained in the OS/2 documentation), you should use either the -s or the -w option. To use drag & drop, create a program object for emacsclient.exe and insert -w %* in the `Parameters' field of the `Program' page of the settings notebook. Using Ispell ============ You can get an emx port of the spelling checker Ispell by anonymous ftp: ftp-os2.nmsu.edu: os2/2_x/unix/unixutils/isp3009b.zip You should use the ispell.el file that comes with Ispell instead of the ispell.el file that comes with GNU Emacs. To use Ispell, add the following statements to your .emacs or site-start.el file, using correct path names: --------------------------------------------------------------------- (setq ispell:program-name "c:/ispell/ispell.exe") (fmakunbound 'ispell-buffer) (fmakunbound 'ispell) (autoload 'ispell-word "c:/ispell/ispell" "Check the spelling of word in buffer." t) (global-set-key "\e$" 'ispell-word) (autoload 'ispell-region "c:/ispell/ispell" "Check the spelling of region." t) (autoload 'ispell-buffer "c:/ispell/ispell" "Check the spelling of buffer." t) (autoload 'ispell-complete-word "c:/ispell/ispell" "Look up current word in dictionary and try to complete it." t) (autoload 'ispell-change-dictionary "c:/ispell/ispell" "Change ispell dictionary." t) (defalias 'ispell 'ispell-buffer) --------------------------------------------------------------------- Moreover, you should replace the current definition of highlight-spelling-error-v19 in ispell.el with --------------------------------------------------------------------- (defun highlight-spelling-error-v19 (start end &optional highlight) (if highlight (progn (setq ispell-overlay (make-overlay start end)) (overlay-put ispell-overlay 'face 'highlight)) (delete-overlay ispell-overlay))) --------------------------------------------------------------------- Probably later versions of ispell.el have an appropriate definition of highlight-spelling-error-v19. More environment variables ========================== The user-name variable is initialized from the value of the USER environment variable. If USER is not set, the LOGNAME environment variable is used. If both USER and LOGNAME are not set, user-name is set to "unknown". The user-full-name variable is initialized from the value of the USERFULLNAME environment variable. If USERFULLNAME is not set, user-full-name is set to "unkown". Miscellaneous hints =================== - For best results, run emacs.exe from the drive where it is installed -- you can change the drive in GNU Emacs. - To change the cursor size in text mode, put cursor -80 -100 into a batch file which runs emacs.exe (unfortunately, cmd.exe changes the cursor size when displaying a prompt). Negative cursor command line arguments are percentages -- the above example makes the cursor use the bottom 20% of the character cell. - The colors defined in term/pm-win.el are designed for 256-color graphics modes. You might have to modify the value of pm-color-alist for 16-color graphics modes. For instance, "darkseagreen2" is gray in 16-color graphics modes. Probably you should use [0 255 255] (cyan) for "darkseagreen2". Additional features of GNU Emacs 19.17 for emx ============================================== Additional functions (see on-line help for details): emacs-priority emx-add-binary-mode filesystem-type keyboard-type file-name-valid-p pm-menu-bar-mode Additional variables (see on-line help for details): emx-binary-mode emx-shell-regexp min-skip-run pm-color-alist Additional command line options for PM: -d Use windowing system (note: no argument!) -name NAME Set name of frame (displayed in the titlebar) -font FONT Select font -background COLOR Select default background color -foreground COLOR Select default foreground color -T NAME See -name -fn FONT See -font -fg COLOR See -foreground -bg COLOR See -background Example: emacs -d -fg white -bg darkblue -fn 8.Courier myfile.c Fonts: A font is specified by size (printer's points) and name: SIZE.NAME Colors: black white blue red pink green cyan yellow darkgray darkblue darkred darkpink darkgreen darkcyan brown palegray ...and others, see pm-color-alist in term/pm-win.el Additional frame parameters for modify-frame-parameters and default-frame-alist: name String Window title font String Font background-color String Default background color foreground-color String Default foreground color alt-modifier Symbol Modifier generated by left Alt key altgr-modifier Symbol Modifier generated by AltGr key cursor-type Symbol Cursor type cursor-blink Boolean Blinking cursor pm-menu-bar Boolean Display Presentation Manager menu bar shortcuts Boolean Enable F1, F10, A-f4, A-space etc. mouse-buttons String Swap mouse buttons height Integer Height of window, in lines width Integer Widtht of window, in columns left Integer horizontal position, in pixels top Integer vertical position, in pixels Alt modifiers: alt The ALT key generates the A- modifier meta The ALT key generates the M- modifier hyper The ALT key generates the H- modifier super The ALT key generates the s- modifier Cursor types: bar A thin vertical bar box A filled box (default) frame The outline of a box underline A horizontal line below the characters halftone A filled box (gray) Mouse buttons: The argument of the mouse-buttons parameter is a string of 3 characters. The first character defines the event generated by the left mouse button, the second character defines the event generates by the middle mouse button (which doesn't exist on two-button mice), the third character defines the event generated by the right mouse button. Each character is either 1 (mouse-1), 2 (mouse-2), 3 (mouse-3) or a space (no event). The default is "132", according to OS/2 conventions. With this value, a two-button mouse cannot generate a mouse-3 event. Example: (setq default-frame-alist (append default-frame-alist '((background-color . "darkblue") (foreground-color . "white") (alt-modifier . alt) (altgr-modifier . hyper) (font . "8.Courier") (mouse-buttons . "123")))) Missing features, misfeatures, bugs =================================== - The emacs-priority variable is ignored. Use the emacs-priority function instead. Note that lisp/term/pm-win.el calls emacs-priority. - interrupt-process doesn't work unless the process is an immediate child of Emacs or is an emx program. Therefore, comint-interrupt-subjob (C-c C-c) doesn't work. - Extended attributes are not preserved in files edited or copied. - The timestamps of all events but mouse button events are always 0. - Scrollbars are not implemented. - Several functions specific to X Windows are missing. - When clicking on the title bar while a popup menu is active which has not been opened by a down-mouse-# event, Emacs hangs. - You have to release the mouse button before clicking on a popup menu activated by clicking on the the (non-PM) menu bar. - OS/2 does not support all three-button mice. Therefore, you can use only two buttons with certain mice. RODENT.SYS, a shareware mouse driver written by Michael Lee Finney (m.finney@genie.geis.com) supports additional three-button mice. Look for RODENT.ZIP or RODNT100.ZIP. Unfortunately, the registration cost is likely to exceed the cost of a new mouse... - Drag & drop is not implemented. Instead of dropping a file on (a running instance of) GNU Emacs, you should drop the file on an emacsclient icon. See above for proper installation of emacsclient. - Emacs doesn't know that trailing dots in file names are ignored by OS/2. It believes that "foo" and "foo." are different files. - The `Choose Pasting Selection' item of the Edit menu doesn't work. - The current implementation of binary mode (using a file name handler) collides with ange-ftp. - The client windows aren't repainted while a popup menu is active. Compiling GNU Emacs =================== The following programs are required for compiling GNU Emacs 19 for emx: - dmake 3.8 - emx 0.8g (or later), GCC 2.4 (or later), etc. for emx - GNU Bison 1.19 (or later) - GNU sed 1.16 (or later) - cp, mv, rm, chmod (GNU file utilities 1.4 or later) You can find all these programs on ftp.informatik.tu-muenchen.de, somewhere under pub/comp/os/os2. To compile GNU Emacs, you have to install the source code: cd \ unzip a:e17src To compile GNU Emacs, type cd \emacs\19.17 configure cd lib-src make cd ..\src mmake make If emx-patch.el and emx-funcs.el have not been byte-compiled (emx-patch.elc and emx-funcs.elc don't exist), the message Pure Lisp storage exhausted may be displayed in the make step in the src directory. Type temacs -batch -l emx-bc to byte-compile these files. Ignore the warning messages which start with **. Then, restart make. IMPORTANT: emx-bc.el assumes that the .el files are in ../lisp. Note: src/Makefile is currently not used. Before running the new emacs.exe in \emacs\19.17\src, you should type move ..\etc\doc-19.17.* \emacs\19.17\data To install GNU Emacs in \emacs\19.17\bin, run install.cmd. If the GNU Emacs version number changes (from 19.83 to 19.84, for instance), you have to edit the following files, replacing the old version number with the new one: emx/README emx/emx1.sed emx/emx3.sed emx/emx4.sed src/dist.cmd src/dump.cmd src/install.cmd To debug GNU Emacs, type gdb -s temacs -e emacs.exe source .gdbinit set args -d Note that .gdbinit changes the command line arguments. Therefore, you should use "set args" after loading .gdbinit. To do post-mortem debugging, type gdb -s temacs -e emacs.exe -c core Note that emx.dll versions prior to revision index 14 don't create usable core dump files for emacs.exe: the stack object is missing in the core dump. To make new distribution ZIP files, type cd \emacs\19.17\src install dist cd ..\emx make-dist Who did the emx port of GNU Emacs 19? ===================================== Eberhard Mattes Teckstrasse 81 (TeX: Teckstra{\ss}e) D-71696 Moeglingen (TeX: M\"oglingen) Germany Internet: mattes@azu.informatik.uni-stuttgart.de No telephone calls please!

GNU Emacs for emx is not available on diskettes from the address given above. An emx-related mailing list has been created: emx-list. The address for people to request to be added to or removed from the list is: listserv@ludd.luth.se To subscribe, send a message containing sub emx-list Joe User to listserv@ludd.luth.se. Of course, you should use your name instead of Joe User's name. As there is currently no GNU Emacs for OS/2 related mailing list, you should use the emx mailing list.
