| 40 ;; This file implements DEC-, OpenWindows-, and HP-compatible "Compose" | |
| 41 ;; processing for XEmacs. | |
| 42 | |
| 43 ;; If you are running a version of X which already does compose processing, | |
| 44 ;; then you don't need this file. But the MIT R4 and R5 distributions don't | |
| 45 ;; do compose processing, so you may want to fake it by using this code. | |
| 46 | |
| 47 ;; The basic idea is that there are several ways to generate keysyms which | |
| 48 ;; do not have keys devoted to them on your keyboard. | |
| 49 | |
| 50 ;; The first method is by using "dead" keys. A dead key is a key which, | |
| 51 ;; when typed, does not insert a character. Instead it modifies the | |
| 52 ;; following character typed. So if you typed "dead-tilde" followed by "A", | |
| 53 ;; then "A-tilde" would be inserted. Of course, this requires you to modify | |
| 54 ;; your keyboard to include a "dead-tilde" key on it somewhere. | |
| 55 | |
| 56 ;; The second method is by using a "Compose" key. With a Compose key, you | |
| 57 ;; would type "Compose" then "tilde" then "A" to insert "A-tilde". | |
| 58 | |
| 59 ;; There are a small number of dead keys: acute, grave, cedilla, diaeresis, | |
| 60 ;; circumflex, tilde, and ring. There are a larger number of accented and | |
| 61 ;; other characters accessible via the Compose key, so both are useful. | |
| 62 | |
| 63 ;; To use this code, you will need to have a Compose key on your keyboard. | |
| 64 ;; The default configuration of most X keyboards doesn't contain one. You | |
| 65 ;; can, for example, turn the right "Meta" key into a "Compose" key with | |
| 66 ;; this command: | |
| 67 | |
| 68 ;; xmodmap -e "remove mod1 = Meta_R" -e "keysym Meta_R = Multi_key" | |
| 69 | |
| 70 ;; Multi-key is the name that X (and emacs) know the "Compose" key by. | |
| 71 ;; The "remove..." command is necessary because the "Compose" key must not | |
| 72 ;; have any modifier bits associated with it. This exact command may not | |
| 73 ;; work, depending on what system and keyboard you are using. If it | |
| 74 ;; doesn't, you'll have to read the man page for xmodmap. You might want | |
| 75 ;; to get the "xkeycaps" program from | |
| 76 ;; <URL:http://www.jwz.org/xkeycaps/>, | |
| 77 ;; which is a graphical front end to xmodmap | |
| 78 ;; that hides xmodmap's arcane syntax from you. | |
| 79 | |
| 80 ;; If for some reason you don't want to have a dedicated compose key on your | |
| 81 ;; keyboard, you can use some other key as the prefix. For example, to make | |
| 82 ;; "Meta-Shift-C" act as a compose key (so that "M-C , c" would insert the | |
| 83 ;; character "ccedilla") you could do | |
| 84 | |
| 85 ;; (global-set-key "\M-C" compose-map) | |
| 86 | |
| 87 ;; I believe the bindings encoded in this file are the same as those used | |
| 88 ;; by OpenWindows versions 2 and 3, and DEC VT320 terminals. Please let me | |
| 89 ;; know if you think otherwise. | |
| 90 | |
| 91 ;; Much thanks to Justin Bur <justin@crim.ca> for helping me understand how | |
| 92 ;; this stuff is supposed to work. | |
| 93 | |
| 94 ;; You also might want to consider getting Justin's patch for the MIT Xlib | |
| 95 ;; that implements compose processing in the library. This will enable | |
| 96 ;; compose processing in applications other than emacs as well. You can | |
| 97 ;; get it from export.lcs.mit.edu in contrib/compose.tar.Z. | |
| 98 | |
| 99 ;; This code has one feature that a more "builtin" Compose mechanism could | |
| 100 ;; not have: at any point you can type C-h to get a list of the possible | |
| 101 ;; completions of what you have typed so far. | |
