33 ;; This package is written for for XEmacs v20.*. This is the strokes
|
|
|
34 ;; package. It is intended to allow the user to control XEmacs by
|
|
|
35 ;; means of mouse strokes. Once strokes is loaded, you can always get
|
|
|
36 ;; help be invoking `strokes-help':
|
|
153
|
37
|
|
|
38 ;; > M-x strokes-help
|
|
|
39
|
|
|
40 ;; and you can learn how to use the package. A mouse stroke, for now,
|
|
|
41 ;; can be defined as holding the middle button, for instance, and then
|
|
|
42 ;; moving the mouse in whatever pattern you wish, which you have set
|
|
185
|
43 ;; XEmacs to understand as mapping to a given command. For example,
|
|
|
44 ;; you may wish the have a mouse stroke that looks like a capital `C'
|
|
|
45 ;; which means `copy-region-as-kill'. Treat strokes just like you do
|
|
|
46 ;; key bindings. For example, XEmacs sets key bindings globally with
|
|
|
47 ;; the `global-set-key' command. Likewise, you can do
|
|
153
|
48
|
|
|
49 ;; > M-x global-set-stroke
|
|
|
50
|
|
|
51 ;; to interactively program in a stroke. It would be wise to set the
|
|
|
52 ;; first one to this very command, so that from then on, you invoke
|
|
|
53 ;; `global-set-stroke' with a stroke. likewise, there may eventually
|
|
|
54 ;; be a `local-set-stroke' command, also analogous to `local-set-key'.
|
|
|
55
|
|
|
56 ;; You can always unset the last stroke definition with the command
|
|
|
57
|
|
|
58 ;; > M-x strokes-unset-last-stroke
|
|
|
59
|
|
|
60 ;; and the last stroke that was added to `strokes-global-map' will be
|
|
|
61 ;; removed.
|
|
|
62
|
|
|
63 ;; Other analogies between strokes and key bindings are as follows:
|
|
|
64
|
|
|
65 ;; 1) To describe a stroke binding, you can type
|
|
|
66
|
|
|
67 ;; > M-x describe-stroke
|
|
|
68
|
|
185
|
69 ;; analogous to `describe-key'. It's also wise to have a
|
|
|
70 ;; stroke, like an `h', for help, or a `?', mapped to
|
|
|
71 ;; `describe-stroke'.
|
|
153
|
72
|
|
185
|
73 ;; 2) stroke bindings are set internally through the Lisp function
|
|
153
|
74 ;; `define-stroke', similar to the `define-key' function. some
|
|
|
75 ;; examples for a 3x3 stroke grid would be
|
|
|
76
|
|
|
77 ;; (define-stroke c-mode-stroke-map
|
|
|
78 ;; '((0 . 0) (1 . 1) (2 . 2))
|
|
|
79 ;; 'kill-region)
|
|
|
80 ;; (define-stroke strokes-global-map
|
|
|
81 ;; '((0 . 0) (0 . 1) (0 . 2) (1 . 2) (2 . 2))
|
|
|
82 ;; 'list-buffers)
|
|
|
83
|
|
185
|
84 ;; however, if you would probably just have the user enter in
|
|
|
85 ;; the stroke interactively and then set the stroke to whatever
|
|
|
86 ;; he/she entered. The Lisp function to interactively read a
|
|
|
87 ;; stroke is `strokes-read-stroke'. This is especially helpful
|
|
|
88 ;; when you're on a fast computer that can handle a 9x9 stroke
|
|
|
89 ;; grid.
|
|
153
|
90
|
|
|
91 ;; NOTE: only global stroke bindings are currently implemented,
|
|
|
92 ;; however mode- and buffer-local stroke bindings may eventually
|
|
|
93 ;; be implemented in a future version.
|
|
|
94
|
|
|
95 ;; The important variables to be aware of for this package are listed
|
|
|
96 ;; below. They can all be altered through the customizing package via
|
|
|
97
|
|
|
98 ;; > M-x customize
|
|
|
99
|
|
|
100 ;; and customizing the group named `strokes'. You can also read
|
|
|
101 ;; documentation on the variables there.
|
|
|
102
|
|
185
|
103 ;; `strokes-minimum-match-score' (determines the threshold of error
|
|
|
104 ;; that makes a stroke acceptable or unacceptable. If your strokes
|
|
|
105 ;; aren't matching, then you should raise this variable.
|
|
153
|
106
|
|
185
|
107 ;; `strokes-grid-resolution' (determines the grid dimensions that you
|
|
|
108 ;; use when defining/reading strokes. The finer the grid your
|
|
|
109 ;; computer can handle, the more you can do, but even a 3x3 grid is
|
|
|
110 ;; pretty cool.) The default value (7) should be fine for most decent
|
|
|
111 ;; computers. NOTE: This variable should not be set to a number less
|
|
|
112 ;; than 3.
|
|
153
|
113
|
|
|
114 ;; `strokes-display-strokes-buffer' will allow you to hide the strokes
|
|
|
115 ;; buffer when doing simple strokes. This is a speedup for slow
|
|
|
116 ;; computers as well as people who don't want to see their strokes.
|
|
|
117
|
|
|
118 ;; If you find that your mouse is accelerating too fast, you can
|
|
|
119 ;; execute the UNIX X command to slow it down. A good possibility is
|
|
|
120
|
|
|
121 ;; % xset m 5/4 8
|
|
|
122
|
|
|
123 ;; which seems, heuristically, to work okay, without much disruption.
|
|
|
124
|
|
|
125 ;; Whenever you load in the strokes package, you will be able to save
|
|
|
126 ;; what you've done upon exiting XEmacs. You can also do
|
|
|
127
|
|
|
128 ;; > M-x save-strokes
|
|
|
129
|
|
185
|
130 ;; and it will save your strokes in ~/.strokes, or you may wish to
|
|
|
131 ;; change this by setting the variable `strokes-file'.
|
|
153
|
132
|
|
|
133 ;; Note that internally, all of the routines that are part of this
|
|
185
|
134 ;; package are able to deal with complex strokes, as they are a
|
|
|
135 ;; superset of simple strokes. However, the default of this package
|
|
|
136 ;; will map mouse button2 to the command `strokes-do-stroke', and NOT
|
|
|
137 ;; `strokes-do-complex-stroke'. If you wish to use complex strokes,
|
|
|
138 ;; you will have to override this key mapping. Complex strokes are
|
|
|
139 ;; terminated with mouse button3. The strokes package will not
|
|
|
140 ;; interfere with `mouse-yank', but you may want to examine how this
|
|
|
141 ;; is done (see the variable `strokes-click-command')
|
|
153
|
142
|
|
|
143 ;; To get strokes to work as part of your your setup, then you'll have
|
|
185
|
144 ;; put the strokes package in your load-path (preferably
|
|
|
145 ;; byte-compiled) and then add the following to your .emacs file (or
|
|
|
146 ;; wherever you put XEmacs-specific startup preferences):
|
|
153
|
147
|
|
189
|
148 ;; (and (console-on-window-system-p)
|
|
|
149 ;; (require 'strokes))
|
|
153
|
150
|
|
|
151 ;; Once loaded, you can start stroking. You can also toggle between
|
|
|
152 ;; strokes mode by simple typing
|
|
|
153
|
|
|
154 ;; > M-x strokes-mode
|
|
|
155
|
|
185
|
156 ;; I am now in the process of porting this package to Emacs. I also
|
|
|
157 ;; hope that, with the help of others, this package will be useful in
|
|
|
158 ;; entering in pictographic-like language text using the mouse
|
|
|
159 ;; (i.e. Korean). Japanese and Chinese are a bit trickier, but I'm
|
|
|
160 ;; sure that with help it can be done. The next version will allow
|
|
|
161 ;; the user to enter strokes which "remove the pencil from the paper"
|
|
|
162 ;; so to speak, so one character can have multiple strokes.

175 ;; Great thanks to Rob Ristroph for his generosity in letting me use
|
|
|
176 ;; his PC to develop this, Jason Johnson for his help in algorithms,
|
|
|
177 ;; Euna Kim for her help in Korean, and massive thanks to the helpful
|
|
|
178 ;; guys on the help instance on athena (zeno, jered, amu, gsstark,
|
|
|
179 ;; ghudson, etc) Special thanks to Steve Baur, Kyle Jones, and Hrvoje
|
|
|
180 ;; Niksic for all their help. And special thanks to Dave Gillespie
|
|
|
181 ;; for all the elisp help--he is responsible for helping me use the cl
|
|
|
182 ;; macros at (near) max speed.
|
|
153
|
183
|
|
|
184 ;; Tasks: (what I'm getting ready for future version)...
|
|
|
185 ;; 2) use 'strokes-read-complex-stroke for korean, etc.
|
|
|
186 ;; 4) buffer-local 'strokes-local-map, and mode-stroke-maps would be nice
|
|
|
187 ;; 6) add some hooks, like `strokes-read-stroke-hook'
|
|
|
188 ;; 7) See what people think of the factory settings. Should I change
|
|
|
189 ;; them? They're all pretty arbitrary in a way. I guess they
|
|
|
190 ;; should be minimal, but computers are getting lots faster, and
|
|
|
191 ;; if I choose the defaults too conservatively, then strokes will
|
|
185
|
192 ;; surely disappoint some people on decent machines (until they
|
|
153
|
193 ;; figure out M-x customize). I need feedback.
|
|
|
194 ;; Other: I always have the most beta version of strokes, so if you
|
|
|
195 ;; want it just let me know.

|
|
197 ;;; Change Log:
|
|
|
198
|
|
185
|
199 ;; 1.3: provided user variable `strokes-use-strokes-buffer' to let
|
|
|
200 ;; users hide the strokes and strokes buffer when entering simple
|
|
|
201 ;; strokes.
|
|
153
|
202 ;; 1.3: cleaned up most leaks.
|
|
|
203 ;; 1.3: with Jari Aalto's help, cleaned up overall program.
|
|
|
204 ;; 1.3: added `strokes-help' for help on strokes
|
|
|
205 ;; 1.3: fixed 'strokes-load-hook bug
|
|
|
206 ;; 1.3: email address change: now <cadet@mit.edu>
|
|
185
|
207 ;; 1.3: added `strokes-report-bug' based on efs/dired's
|
|
|
208 ;; `dired-report-bug'
|
|
153
|
209 ;; 1.3: added more dialog-box queries for mouse-event stuff.
|
|
|
210 ;; 1.4: allowed strokes to invoke kbd macros as well (thanks gsstark!)
|
|
|
211 ;; 2.0: fixed up ordering of certain functions.
|
|
185
|
212 ;; 2.0: fixed bug applying to strokes in dedicated and minibuffer
|
|
|
213 ;; windows.
|
|
153
|
214 ;; 2.0: punted the C-h way of invoking strokes help routines.
|
|
|
215 ;; 2.0: fixed `strokes-define-stroke' so it would error check against
|
|
185
|
216 ;; defining strokes that were too short (really clicks) 2.0:
|
|
|
217 ;; added `strokes-toggle-strokes-buffer' interactive function
|
|
|
218 ;; 2.0: added `customize' support, thanks to patch from Hrvoje
|
|
|
219 ;; (thanks)
|
|
|
220 ;; 2.1: strokes no longer forces `mouse-yank-at-point' to t on
|
|
|
221 ;; mouse-yank (i.e. `mouse-yank-at-point' is up to you again)
|
|
153
|
222 ;; 2.1: toggling strokes-mode off and then back on no longer deletes
|
|
|
223 ;; the strokes that you programmed in but didn't save before
|
|
|
224 ;; toggling off strokes-mode.
|
|
185
|
225 ;; 2.1: advised may functions for modes like VM and w3 so that they
|
|
|
226 ;; too can use strokes, while still maintaining old button2
|
|
|
227 ;; functionality.
|
|
|
228 ;; 2.1: with Steve's help, got the autoload for `strokes-mode' and
|
|
153
|
229 ;; fixed up the package so loading it does not enable strokes
|
|
|
230 ;; until user calls `strokes-mode'.
|
|
|
231 ;; 2.2: made sure that abbrev-mode was off in the ` *strokes*' buffer
|
|
|
232 ;; 2.2: added more dired advice for mouse permissions commands
|
|
185
|
233 ;; 2.2: added some checks to see if saving strokes is really necessary
|
|
|
234 ;; so the user doesn't get prompted aimlessly.
|
|
|
235 ;; 2.2: change the `strokes-lift' symbol to a keyword of value
|
|
|
236 ;; `:strokes-lift' for legibility. IF YOUR OLD STROKES DON'T
|
|
|
237 ;; WORK, THIS IS PROBABLY WHY.
|
|
|
238 ;; 2.2: I might have to change this back to `'strokes-lift' because
|
|
|
239 ;; the keyword fails in emacs, though I don't know why.
|
|
153
|
240 ;; 2.2: `strokes-describe-stroke' is nicer during recursive edits
|
|
|
241 ;; 2.2: provided `strokes-fill-stroke' to fill in empty spaces of strokes
|
|
|
242 ;; as an important step towards platform (speed) independence.
|
|
185
|
243 ;; Because of this, I moved the global setting of
|
|
|
244 ;; `strokes-last-stroke' from
|
|
|
245 ;; `strokes-eliminate-consecutive-redundancies' to
|
|
|
246 ;; `strokes-fill-stroke' since the latter comes later in
|
|
|
247 ;; processing a user stroke.
|
|
153
|
248 ;; 2.2: Finally changed the defaults, so now `strokes-grid-resolution' is 9
|
|
185
|
249 ;; and `strokes-minimum-match-score' is 1000 by default. This
|
|
|
250 ;; will surely mess some people up, but if so, just set it back
|
|
|
251 ;; w/ M-x customize.
|
|
|
252 ;; 2.2: Fixed up the mechanism for updating the
|
|
|
253 ;; `strokes-window-configuration'. Now it only uses one function
|
|
|
254 ;; (`strokes-update-window-configuration') which does it all, and
|
|
|
255 ;; much more efficiently (thanks RMS!).
|
|
|
256 ;; 2.2 Fixed up the appearance of the *strokes* buffer so that there
|
|
|
257 ;; are no ugly line truncations, and I got rid of the bug which
|
|
|
258 ;; would draw the stroke on the wrong line. I still wish that
|
|
|
259 ;; `event-closest-point' was smarter. In fact,
|
|
|
260 ;; `event-closest-point' does *not* do what its name suggests.
|
|
|
261 ;; 2.3 Added more to `strokes-update-window-configuration' so it goes
|
|
|
262 ;; to hell less often
|
|
|
263 ;; 2.3 `strokes-mode' no longer will undefined keys unless it's sure
|
|
|
264 ;; that the user had had them mapped to a strokes command.
|
|
|
265 ;; 2.3 Added more magic autoload statements so strokes work more
|
|
|
266 ;; smoothly. similarly, I made strokes-mode turn itself on when
|
|
|
267 ;; the user defines a stroke (thanks Hrvoje).
|
|
|
268 ;; 2.3 Added "Strokes" to the modeline when strokes is on, and allow
|
|
|
269 ;; toggling strokes with mouse button2.
|
|
|
270 ;; 2.3 Added `list-strokes', which is a really nice function which
|
|
|
271 ;; graphically lists all the strokes that the user has defined
|
|
|
272 ;; and their corresponding commands. `list-strokes' will
|
|
|
273 ;; appropriately colorize the pixmaps to display some time info.
|
|
|
274 ;; 2.4 Added all new functionality to strokes by allowing the user to
|
|
|
275 ;; enter strokes in graphically into XEmacs, allowing true graphic
|
|
|
276 ;; editing, Chinese/Japanese, etc. User simply uses C-button2 to
|
|
|
277 ;; draw strokes (function: `strokes-compose-complex-stroke'). Then
|
|
|
278 ;; after the glyph gets inserted into the current buffer at (point),
|
|
|
279 ;; the use can treat that glyph as any other character, and
|
|
|
280 ;; copy/paste/delete/undo, etc. Also, when the user would like to
|
|
|
281 ;; save/send the glyphs (to other XEmacs users, of course), he/she
|
|
|
282 ;; can use the helper functions:
|
|
|
283 ;;
|
|
|
284 ;; i. M-x strokes-encode-buffer -- Ascii-encodes and compresses
|
|
|
285 ;; strokes to base-64.
|
|
|
286 ;; ii. M-x strokes-decode-buffer -- Decodes ascii-encoded strokes
|
|
|
287 ;; back into glyphs.
|
|
|
288 ;; 2.4 With help from Kyle fixed the itimer (timeout event) bug, where I
|
|
|
289 ;; forgot to check for timeouts.
|
|
|
290 ;; 2.4 Around this time, made a successful port of strokes.el for emacs.
|
|
|
291 ;; 2.4 Made added `strokes-xpm-header' as a variable.
|
|
|
292 ;; 2.4 Changed the default value of `strokes-character' from `o' to
|
|
|
293 ;; `@' since it looks nicer when drawn.
|
|
|
294 ;; 2.4 Changed `strokes-click-p' so that it considers only a stroke
|
|
|
295 ;; of length <= 1 a click, as opposed to a length 2 being a
|
|
|
296 ;; click.
|
|
|
297 ;; 2.4 Totally made the the function `strokes-read-stroke' (and a bit
|

|

302 ;; 2.4 Finally fixed the mouse-yank / mouse-yank-at-point bug (after
|
|
|
303 ;; months of struggling with it). I simply inserted a (sit-for 0)
|
|
|
304 ;; before the (command-execute strokes-click-command) and that
|
|
|
305 ;; patched it up. I'd thought that it was a kludge, but I later
|
|
|
306 ;; found out that it wasn't, as redisplay has several states, and
|
|
|
307 ;; command-execute often must decide which of two states must be
|
|
|
308 ;; considered when executing a command. The (sit-for 0) merely
|
|
|
309 ;; allowed redisplay to be sure to wait for the ` *strokes*'
|
|
|
310 ;; buffer to vanish before executing the command (thanks for the
|
|
|
311 ;; explanation of why my frobbing worked Kyle). Fixing this bug
|
|
|
312 ;; also (magically) fixed the bug which prevented strokes from
|
|
|
313 ;; executing a stroke in a mode which had it's own binding for
|
|
|
314 ;; button-2, such as w3 when the variable
|
|
|
315 ;; `strokes-use-strokes-buffer' is non-nil. It used to be that
|
|
|
316 ;; if you chose to view your strokes, then you couldn't use
|
|
|
317 ;; strokes properly in modes like VM or w3. Now you can!
|
|
|
318 ;; 2.4 Replaced `kill-emacs-hook' with `kill-emacs-query-functions'
|
|
|
319 ;; for prompting the user to save his/her strokes, since
|
|
|
320 ;; `kill-emacs-hook' was not the right hook to use.
|
|
|
321 ;; 2.4 Having `strokes-update-window-configuration' bound to
|
|
|
322 ;; `select-frame-hook' was a heavy function for such a commonly
|
|
|
323 ;; run hook -- especially since event-Xt.c (?) will add the
|
|
|
324 ;; eval-event to the event queue. So the effect was that if XEmacs
|
|
|
325 ;; was doing an interpreter-intensive task while the user (re)selected
|
|
|
326 ;; the frame n times, then the intensive window config updating
|
|
|
327 ;; took place n times. So to deal, I put in some extra checks to
|
|
|
328 ;; see if the frame parameters really changed, making an update
|
|
|
329 ;; worthwhile. See `strokes-update-window-configuration-plist'.
|

|
332 ;; knows how inefficient the hash function was before the advent of

1157 ** Strokes...
|
|
|
1158
|
|
153
|
1159 The strokes package allows you to define strokes (that you make with
|
|
|
1160 the mouse or other pointer device) that XEmacs can interpret as
|
|
|
1161 corresponding to commands, and then executes the commands. It does
|
|
|
1162 character recognition, so you don't have to worry about getting it
|
|
|
1163 right every time.
|
|
|
1164
|
|
185
|
1165 Strokes also allows you to compose documents graphically. You can
|
|
|
1166 fully edit documents in Chinese, Japanese, etc. based on XEmacs
|
|
|
1167 strokes. Once you've done so, you can ascii compress-and-encode them
|
|
|
1168 and then safely save them for later use, send letters to friends
|
|
|
1169 (using XEmacs, of course). Strokes will later decode these documents,
|
|
|
1170 extracting the strokes for editing use once again, so the editing
|
|
|
1171 cycle can continue.
|
|
|
1172
|
|
153
|
1173 Strokes are easy to program and fun to use. To start strokes going,
|
|
|
1174 you'll want to put the following line in your .emacs file:
|
|
|
1175
|
|
185
|
1176 (if window-system
|
|
|
1177 (require 'strokes))
|
|
153
|
1178
|
|
|
1179 This will load strokes when and only when you start XEmacs on a window
|
|
|
1180 system (i.e. that has a pointer (mouse) device, etc.).
|
|
|
1181
|
|
|
1182 To toggle strokes-mode, you just do
|
|
|
1183
|
|
|
1184 > M-x strokes-mode
|
|
|
1185
|
|
185
|
1186 ** Strokes for controlling the behavior of XEmacs...
|
|
|
1187
|
|
153
|
1188 When you're ready to start defining strokes, just use the command
|
|
|
1189
|
|
|
1190 > M-x global-set-stroke
|
|
|
1191
|
|
|
1192 You will see a ` *strokes*' buffer which is waiting for you to enter in
|
|
|
1193 your stroke. When you enter in the stroke, you draw with button1 or
|
|
|
1194 button2, and then end with button3. Next, you enter in the command
|
|
|
1195 which will be executed when that stroke is invoked. Simple as that.
|
|
|
1196 For now, try to define a stroke to copy a region. This is a popular
|
|
|
1197 edit command, so type
|
|
|
1198
|
|
|
1199 > M-x global-set-stroke
|
|
|
1200
|
|
|
1201 Then, in the ` *strokes*' buffer, draw the letter `C' (for `copy')
|
|
|
1202 and then, when it asks you to enter the command to map that to, type
|
|
|
1203
|
|
|
1204 > copy-region-as-kill
|
|
|
1205
|
|
|
1206 That's about as hard as it gets.
|
|
|
1207 Remember: paint with button1 or button2 and then end with button3.
|
|
|
1208
|
|
|
1209 If ever you want to know what a certain strokes maps to, then do
|
|
|
1210
|
|
|
1211 > M-x describe-stroke
|
|
|
1212
|
|
|
1213 and you can enter in any arbitrary stroke. Remember: The strokes
|
|
|
1214 package lets you program in simple and complex (multi-lift) strokes.
|
|
|
1215 The only difference is how you *invoke* the two. You will most likely
|
|
|
1216 use simple strokes, as complex strokes were developed for
|
|
|
1217 Chinese/Japanese/Korean. So the middle mouse button (button2) will
|
|
|
1218 invoke the command `strokes-do-stroke' in buffers where button2 doesn't
|
|
|
1219 already have a meaning other than its original, which is `mouse-yank'.
|
|
|
1220 But don't worry: `mouse-yank' will still work with strokes (see the
|
|
|
1221 variable `strokes-click-command').
|
|
|
1222
|
|
|
1223 If ever you define a stroke which you don't like, then you can unset
|
|
|
1224 it with the command
|
|
|
1225
|
|
|
1226 > M-x strokes-unset-last-stroke
|
|
|
1227
|
|
|
1228 You can always get an idea of what your current strokes look like with
|
|
|
1229 the command
|
|
|
1230
|
|
|
1231 > M-x list-strokes
|
|
|
1232
|
|
177
|
1233 Your strokes will be displayed in alphabetical order (based on command
|
|
|
1234 names) and the beginning of each simple stroke will be marked by a
|
|
|
1235 color dot. Since you may have several simple strokes in a complex
|
|
|
1236 stroke, the dot colors are arranged in the rainbow color sequence,
|
|
|
1237 `ROYGBIV'. If you want a listing of your strokes from most recent
|
|
|
1238 down, then use a prefix argument:
|
|
|
1239
|
|
|
1240 > C-u M-x list-strokes
|
|
153
|
1241
|
|
|
1242 Your strokes are stored as you enter them. They get saved in a file
|
|
|
1243 called ~/.strokes, along with other strokes configuration variables.
|
|
|
1244 You can change this location by setting the variable `strokes-file'.
|
|
|
1245 You will be prompted to save them when you exit XEmacs, or you can save
|
|
|
1246 them with
|
|
|
1247
|
|
|
1248 > M-x save-strokes
|
|
|
1249
|
|
|
1250 Your strokes get loaded automatically when you enable `strokes-mode'.
|
|
|
1251 You can also load in your user-defined strokes with
|
|
|
1252
|
|
|
1253 > M-x load-user-strokes
|
|
|
1254
|
|

|
1255 ** Strokes for pictographic editing...
|
|
153
|
1256
|
|
185
|
1257 If you'd like to create graphical files with strokes, you'll have to
|
|
|
1258 be running XEmacs on a window system, with XPM support. You use the
|

1259 binding C-button2 to start drawing your strokes. These are just
|
|
|
1260 complex strokes, and thus you continue drawing with buttons 1 or 2 and
|
|
|
1261 end with button-3. Then the stroke glyph gets inserted into the
|
|
|
1262 buffer. You treat it like any other character, which you can copy,
|
|
|
1263 paste, delete, move, etc. The command which is bound to C-button2 is
|
|
|
1264 called `strokes-compose-complex-stroke'. When all is done, you may
|
|
|
1265 want to send the file, or save it. This is done with
|
|
153
|
1266
|
|
185
|
1267 > M-x strokes-encode-buffer
|
|
|
1268
|
|
|
1269 Likewise, to decode the strokes from a strokes-encoded buffer you do
|
|
|
1270
|
|
|
1271 > M-x strokes-decode-buffer
|
|
|
1272
|
|
|
1273 ** A few more important things...
|
|
|
1274
|
|
|
1275 o The command `strokes-do-complex-stroke' is invoked with M-button2, so that you
|
|
|
1276 can execute complex strokes (i.e. with more than one lift) if preferred.
|
|
153
|
1277
|
|
|
1278 o Strokes are a bit computer-dependent in that they depend somewhat on
|
|
|
1279 the speed of the computer you're working on. This means that you
|
|
|
1280 may have to tweak some variables. You can read about them in the
|
|
|
1281 commentary of `strokes.el'. Better to just use apropos and read their
|
|
|
1282 docstrings. All variables/functions start with `strokes'. The one
|
|
|
1283 variable which many people wanted to see was
|
|
|
1284 `strokes-use-strokes-buffer' which allows the user to use strokes
|
|
|
1285 silently--without displaying the strokes. All variables can be set
|
|
|
1286 by customizing the group named `strokes' via the customization package:
