In particular, it can make minor adjustments to the Xsystem's keyboard scancodes to allow all "alt" keys to be used in the Xgnuemacs meta-mode. Aside from the system default and emacs maps, any Xkeyboard map may be manually added to a "kbmap.table" file. X XTwo gnuemacs mappings are available: one that uses the ALT key to Xgenerate 8th bit set letters (<letter>|0x080) and another that follows XAT&T conventions such that the ALT key generates (<esc>N<letter>). X XNote that X11R2 will not recognize 8th bit set letters. If you have XX11R2 and ascii console users, then you should use the 'conventional X<esc>N<letter> mapping - even so, X11 uses it's own keyboard mapping Xwhich is similar to, but not the same as, the default map. X11 will NOT Xrecognize the mappings provided by kbmap. The differences are mostly in Xthe assignment of the keyboard arrow keys to become Dec'ish in nature. X XTo add to the havoc, vtlmgr also takes liberties and twiddles the Xkeyboard mapping. X Xkbmap works on AT&T Unix SysV/386 v3.2.2. It may or may not work on other Xversions of unix. X X XINSTALLATION: Modify the Makefile to select your compiler, default X bin directory and default map table name.

X X Kbmap can create a standard mapping file X (/local/lib/kbmap.table) that contains the system default X mapping as well as an two different emacs mapping that allow X alt to be used as the emacs meta-key. Other keyboard X mappings may be manually added to the kbmap.table file. X X Only root may use this programme from the console. X X It cannot be run from an rc2.d/xxx file or cron. X X True META mapping (with 8th bit set) set with -m cannot be X used with X11R2 (X11 does not use the standard keyboard X maps). If you use X11R2 and the ascii console environments, X the -e option should be used for emacs mapping simply to X ensure that the .emacs files can be used in either mode X without change. X X X OPTIONS X -i Show index of maps recorded in map.table. The map X numbers may be used with the -n option to select maps X by number. X X X -q The query option causes the current scancode table in X the kernal to be compared to all of the tables in X kbmap.table. If a match is found, the name of the X currently active table is printed.

X X X -g Generate a new keyboard map file. The systems current X keyboard map is retrieved and written to the X kbmap.table file. Two mapping files for emacs are X appended. The system's keyboard map is not updated. X X X file Select file to be the generated keyboard map file, X usually kbmap.table. X X X -d Select the system default map from kbmap.table and X update the system's current keyboard map. X X X -e Select the emacs default map from kbmap.table and X update the system's current keyboard map. Emacs users X may use alt as the meta-key. If you press the alt key X and a letter together, the letter is generated with the X escape sequence <esc>N<letter>. X X If this mapping is used, the .emacs files should X contain the following: X X (define-key global-map "\M-N" 'ESC-prefix) X X to enable the recognition of the new escape sequences. X X The only significant change to the AT&T standard X keyboard mapping is that the <alt><del> meta is enabled X to allow backward-kill-word. X X X -m Select the emacs meta-key 8th bit map from kbmap.table X and update the system's current keyboard map. Emacs X users may use alt as the meta-key. If you press the X alt key and a letter together, the letter is generated X as <letter> | 0x080. X X If this mapping is used, the .emacs files should X contain the following: X X (setq meta-flag t) X X to enable the recognition 8th bit set meta characters. X X X11R2 will not recognize 8th bit set characters. As a X result, the -m option should not be used if you intend X to run emacs with X11R2.

X X X -a Normally, kbmap extends mapping for <alt><ctl> and X <alt><shif><ctl> keys. If the -a option is used, these X will be disabled. X X If the -a is used, then the gnuemacs C-M- sequences X (such as C-M-s (isearch-forward-regexp)) cannot use the X <alt><ctl><letter> combinations.

X X X SETUP X Create a basic keyboard mapping file that contains both the X standard map and the emacs meta-key map: X X kbmap -g kbmap.table X X The current keyboard table is fetched. The current mapping X information as described in the keymap_t structure is X written to disk file kbmap.table. The meta-conversion for X emacs is performed on the structure and the resulting X information is appended to kbmap.table. The new information X is NOT updated in the kernal. X X Copy kbmap.table to /local/lib/kbmap.table (or other file as X specified during system compilation.)

X XAUTHOR: Tony Field (tony%ajfcal@cpsc.ucalgary.ca) X XNOTES: X X Structure of keyboard translation table (from /usr/include/sys/kd.h) X X #define NUM_KEYS 256 Maximum number of keys X #define NUM_STATES 8 Number of key states X #pragma pack(2) X typedef struct { X short n_keys ; Number of entries in table X struct key_t { X unsigned char map[NUM_STATES]; Key code for each state X unsigned char spcl; Bits marking states as special X unsigned char flgs; Flags X } key[NUM_KEYS+1]; One entry for each key X } keymap_t; X X (note: NUM_KEYS is specified as 256, however n_keys only X describes 128 keys... kbmap only updates the first X 128 keys. The remainder are unmodified.) X X Each key has 8 (NUM_STATES) possible scan states honoured if X set in the "spcl" field: X X spcl map[i] X bit 7 i=0 = normal X 6 1 = shifted X 5 2 = control X 4 3 = shift-control X 3 4 = alt X 2 5 = alt-shift X 1 6 = alt-control X 0 7 = alt-shift-control X X If the corresponding bit is set, then the feature is enabled. For X example, if bit 3 is set, then the keyboard driver will translate X the scan code into the "<esc>Nx" escape sequence. If the 3ed bit is X NOT set, then the driver will use the character as specified in X map[4] as the returned value. X X The "flgs" field needs no modification: it allows the "numlok", X "caploc" and "control" keys to be used with specific keys: X X 0x8000 allow numlock X 0x4000 allow caps lock X 0x2000 allow control X 0x1000 locking is off X X At leaset that is what <sys/kd.h> indicates. But that is not X what is indicated in the actual dump of the tables... Alphabetic X characters contain 0x01, the numeric keypad contains 0x02, and X verything else contains 0x00. Oh well... A more reasonable X interpretation is that these meanings are assigned to the X high order 4 bits of "spcl", but that is only a guess. X X In addition, the default value for the map[4] entry for most codes X that can be translated into the <esc>Nx sequence is 0x7d. X The 7x numbers are used for function key translation. They mean X (of course i am guessing): X X 7d = use <esc>Nx where 'x' is the un-alted value X 7e = use <esc>Ox of the scan code (funny that 7e X 7f = use <esc>Lx and 7f do not appear in the table X nor are visible in keyboard(7)) X X Conversion of the table to emacs "meta" bits is done as follows: X X 1. read the entire keyboard mapping structure with ioctl(). X 2. if the base key (map[0]) is between ' ' & 0x7f and not uppercase X then remove bit 3 from the spcl field and X set map[4] = map[0] | 0x80. The creates the X meta-mapping of the keys for lower case letters. X 3. if the shifted key (map[1]) is between ' ' & 0x7f and the X map[0] value is not an upper case character, X then remove bit 2 from the spcl field and X set map[5] = map[1] | 0x80. The creates the X meta-mapping of the keys for upper case letters. X 4. write the new keyboard mapping with ioctl(). X X Similar conversion is make for the "normal" emacs <esc>N prefix X sequence. This requires forcing the 0x7d code into all <alt>x slots. X X The map structure contains map[0] entries for both lower and upper X case letters. The lower case entries "seem" to be the only ones X used. No explanation is offered for the upper case entries.
