26 | ;;; Commentary: | |
27 | ||
28 | ;; This is the strokes package. It is intended to allow the user to | |
29 | ;; control Emacs by means of mouse strokes. Once strokes is loaded, you | |
30 | ;; can always get help be invoking `strokes-help': | |
31 | ||
32 | ;; > M-x strokes-help | |
33 | ||
34 | ;; and you can learn how to use the package. A mouse stroke, for now, | |
35 | ;; can be defined as holding the middle button, for instance, and then | |
36 | ;; moving the mouse in whatever pattern you wish, which you have set | |
37 | ;; Emacs to understand as mapping to a given command. For example, you | |
38 | ;; may wish the have a mouse stroke that looks like a capital `C' which | |
39 | ;; means `copy-region-as-kill'. Treat strokes just like you do key | |
40 | ;; bindings. For example, Emacs sets key bindings globally with the | |
41 | ;; `global-set-key' command. Likewise, you can do | |
42 | ||
43 | ;; > M-x global-set-stroke | |
44 | ||
45 | ;; to interactively program in a stroke. It would be wise to set the | |
46 | ;; first one to this very command, so that from then on, you invoke | |
47 | ;; `global-set-stroke' with a stroke. likewise, there may eventually | |
48 | ;; be a `local-set-stroke' command, also analogous to `local-set-key'. | |
49 | ||
50 | ;; You can always unset the last stroke definition with the command | |
51 | ||
52 | ;; > M-x strokes-unset-last-stroke | |
53 | ||
54 | ;; and the last stroke that was added to `strokes-global-map' will be | |
55 | ;; removed. | |
56 | ||
57 | ;; Other analogies between strokes and key bindings are as follows: | |
58 | ||
59 | ;; 1) To describe a stroke binding, you can type | |
60 | ||
61 | ;; > M-x describe-stroke | |
62 | ||
63 | ;; analogous to `describe-key'. It's also wise to have a stroke, | |
64 | ;; like an `h', for help, or a `?', mapped to `describe-stroke'. | |
65 | ||
66 | ;; 2) stroke bindings are set internally through the Lisp function | |
67 | ;; `define-stroke', similar to the `define-key' function. some | |
68 | ;; examples for a 3x3 stroke grid would be | |
69 | ||
70 | ;; (define-stroke c-mode-stroke-map | |
71 | ;; '((0 . 0) (1 . 1) (2 . 2)) | |
72 | ;; 'kill-region) | |
73 | ;; (define-stroke strokes-global-map | |
74 | ;; '((0 . 0) (0 . 1) (0 . 2) (1 . 2) (2 . 2)) | |
75 | ;; 'list-buffers) | |
76 | ||
77 | ;; however, if you would probably just have the user enter in the | |
78 | ;; stroke interactively and then set the stroke to whatever he/she | |
79 | ;; entered. The Lisp function to interactively read a stroke is | |
80 | ;; `strokes-read-stroke'. This is especially helpful when you're | |
81 | ;; on a fast computer that can handle a 9x9 stroke grid. | |
82 | ||
83 | ;; NOTE: only global stroke bindings are currently implemented, | |
84 | ;; however mode- and buffer-local stroke bindings may eventually | |
85 | ;; be implemented in a future version. | |
86 | ||
87 | ;; The important variables to be aware of for this package are listed | |
88 | ;; below. They can all be altered through the customizing package via | |
89 | ||
90 | ;; > M-x customize | |
91 | ||
92 | ;; and customizing the group named `strokes'. You can also read | |
93 | ;; documentation on the variables there. | |
94 | ||
95 | ;; `strokes-minimum-match-score' (determines the threshold of error that | |
0d0db51e | 96 | ;; makes a stroke acceptable or unacceptable. If your strokes aren't |
aea01cd7 RS |
97 | ;; matching, then you should raise this variable. |
98 | ||
99 | ;; `strokes-grid-resolution' (determines the grid dimensions that you use | |
100 | ;; when defining/reading strokes. The finer the grid your computer can | |
101 | ;; handle, the more you can do, but even a 3x3 grid is pretty cool.) | |
102 | ;; The default value (7) should be fine for most decent computers. | |
103 | ;; NOTE: This variable should not be set to a number less than 3. | |
104 | ||
105 | ;; `strokes-display-strokes-buffer' will allow you to hide the strokes | |
106 | ;; buffer when doing simple strokes. This is a speedup for slow | |
107 | ;; computers as well as people who don't want to see their strokes. | |
108 | ||
109 | ;; If you find that your mouse is accelerating too fast, you can | |
110 | ;; execute the UNIX X command to slow it down. A good possibility is | |
111 | ||
112 | ;; % xset m 5/4 8 | |
113 | ||
114 | ;; which seems, heuristically, to work okay, without much disruption. | |
115 | ||
116 | ;; Whenever you load in the strokes package, you will be able to save | |
117 | ;; what you've done upon exiting Emacs. You can also do | |
118 | ||
119 | ;; > M-x save-strokes | |
120 | ||
121 | ;; and it will save your strokes in ~/.strokes, or you may wish to change | |
122 | ;; this by setting the variable `strokes-file'. | |
123 | ||
124 | ;; Note that internally, all of the routines that are part of this | |
125 | ;; package are able to deal with complex strokes, as they are a superset | |
126 | ;; of simple strokes. However, the default of this package will map | |
127 | ;; mouse button2 to the command `strokes-do-stroke', and NOT | |
128 | ;; `strokes-do-complex-stroke'. If you wish to use complex strokes, you | |
129 | ;; will have to override this key mapping. Complex strokes are terminated | |
130 | ;; with mouse button3. The strokes package will not interfere with | |
131 | ;; `mouse-yank', but you may want to examine how this is done (see the | |
132 | ;; variable `strokes-click-command') | |
133 | ||
134 | ;; To get strokes to work as part of your your setup, then you'll have | |
135 | ;; put the strokes package in your load-path (preferably byte-compiled) | |
136 | ;; and then add the following to your .emacs file (or wherever | |
137 | ;; you put Emacs-specific startup preferences): | |
138 | ||
0d0db51e | 139 | ;;(and window-system |
aea01cd7 RS |
140 | ;; (require 'strokes)) |
141 | ||
142 | ;; Once loaded, you can start stroking. You can also toggle between | |
143 | ;; strokes mode by simple typing | |
144 | ||
145 | ;; > M-x strokes-mode | |
146 | ||
147 | ;; I am now in the process of porting this package to Emacs. I also hope | |
148 | ;; that, with the help of others, this package will be useful in entering | |
149 | ;; in pictographic-like language text using the mouse (i.e. Korean). | |
150 | ;; Japanese and Chinese are a bit trickier, but I'm sure that with help | |
151 | ;; it can be done. The next version will allow the user to enter strokes | |
152 | ;; which "remove the pencil from the paper" so to speak, so one character | |
153 | ;; can have multiple strokes. | |
154 | ||
155 | ;; You can read more about strokes at: | |

174 | ;; Tasks: (what I'm getting ready for future version)... | |
175 | ;; 2) use 'strokes-read-complex-stroke for korean, etc. | |
176 | ;; 4) buffer-local 'strokes-local-map, and mode-stroke-maps would be nice | |
aea01cd7 RS |
177 | ;; 6) add some hooks, like `strokes-read-stroke-hook' |
178 | ;; 7) See what people think of the factory settings. Should I change | |
179 | ;; them? They're all pretty arbitrary in a way. I guess they | |
180 | ;; should be minimal, but computers are getting lots faster, and | |
181 | ;; if I choose the defaults too conservatively, then strokes will | |
0d0db51e | 182 | ;; surely disappoint some people on decent machines (until they |

397 | ;; I'd originally wanted to write a macro that would just take in the | |
398 | ;; generic functions which use mouse button2 in various modes. Most of | |
399 | ;; them are identical in form: they take an event as the single argument | |
400 | ;; and then do their thing. I tried writing a macro that looked | |
401 | ;; something like this, but failed. Advice just ain't that easy. The | |
402 | ;; one that bugged me the most was `Manual-follow-xref', because that had | |
403 | ;; &rest arguments, and I didn't know how to work around it in defadvice. | |
404 | ;; However, I was able to fix up most of the important modes (i.e. the | |
405 | ;; ones I use all the time). One `bug' in the program that I just can't | |
406 | ;; seem to figure out is why I can only advise other button2 functions | |
407 | ;; successfully when the variable `strokes-use-strokes-buffer' is nil. I | |
408 | ;; did all the save-excursion/save-window-excursion stuff SPECIFICALLY so | |
409 | ;; that using the strokes buffer or not would absolutely not affect any | |
410 | ;; other part of the program. If someone can figure out how to make the | |
411 | ;; following advices work w/ regardless of that variable | |

7bd27aed | 1045 | ** Strokes... |
aea01cd7 | 1046 | |
7bd27aed RS |
1047 | The strokes package allows you to define strokes, made with |
1048 | the mouse or other pointer device, that Emacs can interpret as | |
1049 | corresponding to commands, and then executes the commands. It does | |
1050 | character recognition, so you don't have to worry about getting it | |
1051 | right every time. | |
aea01cd7 | 1052 | |
0d0db51e DL |
1053 | Strokes also allows you to compose documents graphically. You can |
1054 | fully edit documents in Chinese, Japanese, etc. based on XEmacs | |
1055 | strokes. Once you've done so, you can ascii compress-and-encode them | |
1056 | and then safely save them for later use, send letters to friends | |
1057 | \(using Emacs, of course). Strokes will later decode these documents, | |
1058 | extracting the strokes for editing use once again, so the editing | |
1059 | cycle can continue. | |
1060 | ||
7bd27aed RS |
1061 | Strokes are easy to program and fun to use. To start strokes going, |
1062 | you'll want to put the following line in your .emacs file as mentioned | |
1063 | in the commentary to strokes.el. | |
aea01cd7 | 1064 | |
7bd27aed RS |
1065 | This will load strokes when and only when you start Emacs on a window |
1066 | system, with a mouse or other pointer device defined. | |
aea01cd7 | 1067 | |
7bd27aed | 1068 | To toggle strokes-mode, you just do |
aea01cd7 | 1069 | |
7bd27aed | 1070 | > M-x strokes-mode |
aea01cd7 | 1071 | |
0d0db51e | 1072 | ** Strokes for controlling the behavior of Emacs... |
aea01cd7 | 1073 | |
7bd27aed | 1074 | When you're ready to start defining strokes, just use the command |
aea01cd7 | 1075 | |
7bd27aed | 1076 | > M-x global-set-stroke |
aea01cd7 | 1077 | |
7bd27aed RS |
1078 | You will see a ` *strokes*' buffer which is waiting for you to enter in |
1079 | your stroke. When you enter in the stroke, you draw with button1 or | |
1080 | button2, and then end with button3. Next, you enter in the command | |
1081 | which will be executed when that stroke is invoked. Simple as that. | |
1082 | For now, try to define a stroke to copy a region. This is a popular | |
1083 | edit command, so type | |
aea01cd7 | 1084 | |
7bd27aed | 1085 | > M-x global-set-stroke |
aea01cd7 | 1086 | |
0d0db51e | 1087 | Then, in the ` *strokes*' buffer, draw the letter `C' (for `copy') |
7bd27aed | 1088 | and then, when it asks you to enter the command to map that to, type |
aea01cd7 | 1089 | |
7bd27aed | 1090 | > copy-region-as-kill |
aea01cd7 | 1091 | |
7bd27aed RS |
1092 | That's about as hard as it gets. |
1093 | Remember: paint with button1 or button2 and then end with button3. | |
aea01cd7 | 1094 | |
7bd27aed | 1095 | If ever you want to know what a certain strokes maps to, then do |
aea01cd7 | 1096 | |
7bd27aed | 1097 | > M-x describe-stroke |
aea01cd7 | 1098 | |
7bd27aed | 1099 | and you can enter in any arbitrary stroke. Remember: The strokes |
0d0db51e | 1100 | package lets you program in simple and complex (multi-lift) strokes. |
7bd27aed RS |
1101 | The only difference is how you *invoke* the two. You will most likely |
1102 | use simple strokes, as complex strokes were developed for | |
0d0db51e | 1103 | Chinese/Japanese/Korean. So the middle mouse button (mouse-2) will |
7bd27aed RS |
1104 | invoke the command `strokes-do-stroke' in buffers where button2 doesn't |
1105 | already have a meaning other than its original, which is `mouse-yank'. | |
1106 | But don't worry: `mouse-yank' will still work with strokes. See the | |
1107 | variable `strokes-click-command'. | |
aea01cd7 | 1108 | |
7bd27aed RS |
1109 | If ever you define a stroke which you don't like, then you can unset |
1110 | it with the command | |
aea01cd7 | 1111 | |
7bd27aed | 1112 | > M-x strokes-unset-last-stroke |
aea01cd7 | 1113 | |
0d0db51e DL |
1114 | You can always get an idea of what your current strokes look like with |
1115 | the command | |
1116 | ||
1117 | > M-x strokes-list-strokes | |
1118 | ||
1119 | Your strokes will be displayed in alphabetical order (based on command | |
1120 | names) and the beginning of each simple stroke will be marked by a | |
1121 | color dot. Since you may have several simple strokes in a complex | |
1122 | stroke, the dot colors are arranged in the rainbow color sequence, | |
1123 | `ROYGBIV'. If you want a listing of your strokes from most recent | |
1124 | down, then use a prefix argument: | |
1125 | ||
1126 | > C-u M-x strokes-list-strokes | |
1127 | ||
7bd27aed RS |
1128 | Your strokes are stored as you enter them. They get saved in a file |
1129 | called ~/.strokes, along with other strokes configuration variables. | |
1130 | You can change this location by setting the variable `strokes-file'. | |
1131 | You will be prompted to save them when you exit Emacs, or you can save | |
1132 | them with | |
aea01cd7 | 1133 | |
7bd27aed | 1134 | > M-x save-strokes |
aea01cd7 | 1135 | |
7bd27aed RS |
1136 | Your strokes get loaded automatically when you enable `strokes-mode'. |
1137 | You can also load in your user-defined strokes with | |
aea01cd7 | 1138 | |
7bd27aed | 1139 | > M-x load-user-strokes |
aea01cd7 | 1140 | |
0d0db51e DL |
1141 | ** Strokes for pictographic editing... |
1142 | ||
1143 | If you'd like to create graphical files with strokes, you'll have to | |
1144 | be running a version of Emacs with XPM support. You use the | |
1145 | binding C-mouse-2 to start drawing your strokes. These are just | |
1146 | complex strokes, and thus you continue drawing with mouse-1 or mouse-2 and | |
1147 | end with mouse-3-3. Then the stroke image gets inserted into the | |
1148 | buffer. You treat it like any other character, which you can copy, | |
1149 | paste, delete, move, etc. The command which is bound to C-mouse-2 is | |
1150 | called `strokes-compose-complex-stroke'. When all is done, you may | |
1151 | want to send the file, or save it. This is done with | |
1152 | ||
1153 | > M-x strokes-encode-buffer | |
1154 | ||
1155 | Likewise, to decode the strokes from a strokes-encoded buffer you do | |
1156 | ||
1157 | > M-x strokes-decode-buffer | |
1158 | ||
7bd27aed | 1159 | ** A few more important things... |
aea01cd7 | 1160 | |
0d0db51e DL |
1161 | o The command `strokes-do-complex-stroke' is invoked with M-mouse-2, |
1162 | so that you can execute complex strokes (i.e. with more than one lift) | |
1163 | if preferred. | |
aea01cd7 | 1164 | |
7bd27aed RS |
1165 | o Strokes are a bit computer-dependent in that they depend somewhat on |
1166 | the speed of the computer you're working on. This means that you | |
1167 | may have to tweak some variables. You can read about them in the | |
1168 | commentary of `strokes.el'. Better to just use apropos and read their | |
1169 | docstrings. All variables/functions start with `strokes'. The one | |
1170 | variable which many people wanted to see was | |
1171 | `strokes-use-strokes-buffer' which allows the user to use strokes | |
1172 | silently--without displaying the strokes. All variables can be set | |
1173 | by customizing the group named `strokes' via the customization package: | |
