|
|
|
32 ;; This package is written for for XEmacs v19.14 and up.
|
|
|
33 ;; This is the strokes package. It is intended to allow the user to
|
|
|
34 ;; control XEmacs by means of mouse strokes. Once strokes is loaded, you
|
|
|
35 ;; can always get help be invoking `strokes-help':
|
|
|
36
|
|
|
37 ;; > M-x strokes-help
|
|
|
38
|
|
|
39 ;; and you can learn how to use the package. A mouse stroke, for now,
|
|
|
40 ;; can be defined as holding the middle button, for instance, and then
|
|
|
41 ;; moving the mouse in whatever pattern you wish, which you have set
|
|
|
42 ;; XEmacs to understand as mapping to a given command. For example, you
|
|
|
43 ;; may wish the have a mouse stroke that looks like a capital `C' which
|
|
|
44 ;; means `copy-region-as-kill'. Treat strokes just like you do key
|
|
|
45 ;; bindings. For example, XEmacs sets key bindings globally with the
|
|
|
46 ;; `global-set-key' command. Likewise, you can do
|
|
|
47
|
|
|
48 ;; > M-x global-set-stroke
|
|
|
49
|
|
|
50 ;; to interactively program in a stroke. It would be wise to set the
|
|
|
51 ;; first one to this very command, so that from then on, you invoke
|
|
|
52 ;; `global-set-stroke' with a stroke. likewise, there may eventually
|
|
|
53 ;; be a `local-set-stroke' command, also analogous to `local-set-key'.
|
|
|
54
|
|
|
55 ;; You can always unset the last stroke definition with the command
|
|
|
56
|
|
|
57 ;; > M-x strokes-unset-last-stroke
|
|
|
58
|
|
|
59 ;; and the last stroke that was added to `strokes-global-map' will be
|
|
|
60 ;; removed.
|
|
|
61
|
|
|
62 ;; Other analogies between strokes and key bindings are as follows:
|
|
|
63
|
|
|
64 ;; 1) To describe a stroke binding, you can type
|
|
|
65
|
|
|
66 ;; > M-x describe-stroke
|
|
|
67
|
|
|
68 ;; analogous to `describe-key'. It's also wise to have a stroke,
|
|
|
69 ;; like an `h', for help, or a `?', mapped to `describe-stroke'.
|
|
|
70
|
|
|
71 ;; 2) stroke bindings are set internally through the lisp function
|
|
|
72 ;; `define-stroke', similar to the `define-key' function. some
|
|
|
73 ;; examples for a 3x3 stroke grid would be
|
|
|
74
|
|
|
75 ;; (define-stroke c-mode-stroke-map
|
|
|
76 ;; '((0 . 0) (1 . 1) (2 . 2))
|
|
|
77 ;; 'kill-region)
|
|
|
78 ;; (define-stroke strokes-global-map
|
|
|
79 ;; '((0 . 0) (0 . 1) (0 . 2) (1 . 2) (2 . 2))
|
|
|
80 ;; 'list-buffers)
|
|
|
81
|
|
|
82 ;; however, if you would probably just have the user enter in the
|
|
|
83 ;; stroke interactively and then set the stroke to whatever he/she
|
|
|
84 ;; entered. The lisp function to interactively read a stroke is
|
|
|
85 ;; `strokes-read-stroke'. This is especially helpful when you're
|
|
|
86 ;; on a fast computer that can handle a 9x9 stroke grid.
|
|
|
87
|
|
|
88 ;; NOTE: only global stroke bindings are currently implemented,
|
|
|
89 ;; however mode- and buffer-local stroke bindings may eventually
|
|
|
90 ;; be implemented in a future version.
|
|
|
91
|
|
|
92 ;; The important variables to be aware of for this package are listed
|
|
|
93 ;; below. They can all be altered through the customizing package via
|
|
|
94
|
|
|
95 ;; > M-x customize
|
|
|
96
|
|
|
97 ;; and customizing the group named `strokes'. You can also read
|
|
|
98 ;; documentation on the variables there.
|
|
|
99
|
|
|
100 ;; `strokes-minimum-match-score' (determines the threshold of error that
|
|
|
101 ;; makes a stroke acceptable or unacceptable. If your strokes arn't
|
|
|
102 ;; matching, then you should raise this variable.
|
|
|
103
|
|
|
104 ;; `strokes-grid-resolution' (determines the grid dimensions that you use
|
|
|
105 ;; when defining/reading strokes. The finer the grid your computer can
|
|
|
106 ;; handle, the more you can do, but even a 3x3 grid is pretty cool.)
|
|
|
107 ;; The default value (7) should be fine for most decent computers.
|
|
|
108 ;; NOTE: This variable should not be set to a number less than 3.
|
|
|
109
|
|
|
110 ;; `strokes-display-strokes-buffer' will allow you to hide the strokes
|
|
|
111 ;; buffer when doing simple strokes. This is a speedup for slow
|
|
|
112 ;; computers as well as people who don't want to see their strokes.
|
|
|
113
|
|
|
114 ;; If you find that your mouse is accelerating too fast, you can
|
|
|
115 ;; execute the UNIX X command to slow it down. A good possibility is
|
|
|
116
|
|
|
117 ;; % xset m 5/4 8
|
|
|
118
|
|
|
119 ;; which seems, heuristically, to work okay, without much disruption.
|
|
|
120
|
|
|
121 ;; Whenever you load in the strokes package, you will be able to save
|
|
|
122 ;; what you've done upon exiting XEmacs. You can also do
|
|
|
123
|
|
|
124 ;; > M-x save-strokes
|
|
|
125
|
|
|
126 ;; and it will save your strokes in ~/.strokes, or you may wish to change
|
|
|
127 ;; this by setting the variable `strokes-file'.
|
|
|
128
|
|
|
129 ;; Note that internally, all of the routines that are part of this
|
|
|
130 ;; package are able to deal with complex strokes, as they are a superset
|
|
|
131 ;; of simple strokes. However, the default of this package will map
|
|
|
132 ;; mouse button2 to the command `strokes-do-stroke', and NOT
|
|
|
133 ;; `strokes-do-complex-stroke'. If you wish to use complex strokes, you
|
|
|
134 ;; will have to override this key mapping. Complex strokes are terminated
|
|
|
135 ;; with mouse button3. The strokes package will not interfere with
|
|
|
136 ;; `mouse-yank', but you may want to examine how this is done (see the
|
|
|
137 ;; variable `strokes-click-command')
|
|
|
138
|
|
|
139 ;; To get strokes to work as part of your your setup, then you'll have
|
|
|
140 ;; put the strokes package in your load-path (preferably byte-compiled)
|
|
|
141 ;; and then add the following to your .xemacs-options file (or wherever
|
|
|
142 ;; you put XEmacs-specific startup preferences):
|
|
|
143
|
|
|
144 ;;(and (fboundp 'device-on-window-system-p)
|
|
|
145 ;; (device-on-window-system-p)
|
|
|
146 ;; (require 'strokes))
|
|
|
147
|
|
|
148 ;; Once loaded, you can start stroking. You can also toggle between
|
|
|
149 ;; strokes mode by simple typing
|
|
|
150
|
|
|
151 ;; > M-x strokes-mode
|
|
|
152
|
|
|
153 ;; I am now in the process of porting this package to emacs. I also hope
|
|
|
154 ;; that, with the help of others, this package will be useful in entering
|
|
|
155 ;; in pictographic-like language text using the mouse (i.e. Korean).
|
|
|
156 ;; Japanese and Chinese are a bit trickier, but I'm sure that with help
|
|
|
157 ;; it can be done. The next version will allow the user to enter strokes
|
|
|
158 ;; which "remove the pencil from the paper" so to speak, so one character
|
|
|
159 ;; can have multiple strokes.
|
|
|
160
|
|
|
161 ;; Great thanks to Rob Ristroph for his generosity in letting me use his
|
|
|
162 ;; PC to develop this, Jason Johnson for his help in algorithms, Euna
|
|
|
163 ;; Kim for her help in Korean, and massive thanks to the helpful guys
|
|
|
164 ;; on the help instance on athena (zeno, jered, amu, gsstark, ghudson, etc)
|
|
|
165 ;; Special thanks to Steve Baur and Hrvoje Niksic for all their help.
|
|
|
166
|
|
|
167 ;; Tasks: (what I'm getting ready for future version)...
|
|
|
168 ;; 2) use 'strokes-read-complex-stroke for korean, etc.
|
|
|
169 ;; 4) buffer-local 'strokes-local-map, and mode-stroke-maps would be nice
|
|
|
170 ;; 5) 'list-strokes (kinda important). What do people want?
|
|
|
171 ;; How about an optional docstring for each stroke so that a person
|
|
|
172 ;; can examine the strokes-file and actually make sense of it?
|
|
|
173 ;; (e.g. "This stroke is a pentagram")
|
|
|
174 ;; 6) add some hooks, like `strokes-read-stroke-hook'
|
|
|
175 ;; 7) See what people think of the factory settings. Should I change
|
|
|
176 ;; them? They're all pretty arbitrary in a way. I guess they
|
|
|
177 ;; should be minimal, but computers are getting lots faster, and
|
|
|
178 ;; if I choose the defaults too conservatively, then strokes will
|
|
|
179 ;; surely dissapoint some people on decent machines (until they
|
|
|
180 ;; figure out M-x customize). I need feedback.
|
|
|
181 ;; Other: I always have the most beta version of strokes, so if you
|
|
|
182 ;; want it just let me know.

|
183
|
|
|
184 ;;; Change Log:
|
|
|
185
|
|
|
186 ;; 1.3: provided user variable `strokes-use-strokes-buffer' to let users
|
|
|
187 ;; hide the strokes and strokes buffer when entering simple strokes.
|
|
|
188 ;; 1.3: cleaned up most leaks.
|
|
|
189 ;; 1.3: with Jari Aalto's help, cleaned up overall program.
|
|
|
190 ;; 1.3: added `strokes-help' for help on strokes
|
|
|
191 ;; 1.3: fixed 'strokes-load-hook bug
|
|
|
192 ;; 1.3: email address change: now <cadet@mit.edu>
|
|
|
193 ;; 1.3: added `strokes-report-bug' based on efs/dired's `dired-report-bug'
|
|
|
194 ;; 1.3: added more dialog-box queries for mouse-event stuff.
|
|
|
195 ;; 1.4: allowed strokes to invoke kbd macros as well (thanks gsstark!)
|
|
|
196 ;; 2.0: fixed up ordering of certain functions.
|
|
|
197 ;; 2.0: fixed bug applying to strokes in dedicated and minibuffer windows.
|
|
|
198 ;; 2.0: punted the C-h way of invoking strokes help routines.
|
|
|
199 ;; 2.0: fixed `strokes-define-stroke' so it would error check against
|
|
|
200 ;; defining strokes that were too short (really clicks)
|
|
|
201 ;; 2.0: added `strokes-toggle-strokes-buffer' interactive function
|
|
|
202 ;; 2.0: added `customize' support, thanks to patch from Hrvoje (thanks)
|
|
|
203 ;; 2.1: strokes no longer forces `mouse-yank-at-point' to t on mouse-yank
|
|
|
204 ;; (i.e. `mouse-yank-at-point' is up to you again)
|
|
|
205 ;; 2.1: toggling strokes-mode off and then back on no longer deletes
|
|
|
206 ;; the strokes that you programmed in but didn't save before
|
|
|
207 ;; toggling off strokes-mode.
|
|
|
208 ;; 2.1: advised may functions for modes like VM and w3 so that they too
|
|
|
209 ;; can use strokes, while still mantaining old button2 functionality.
|
|
|
210 ;; 2.1: with steve's help, got the autoload for `strokes-mode' and
|
|
|
211 ;; fixed up the package so loading it does not enable strokes
|
|
|
212 ;; until user calls `strokes-mode'.
|
|
|
213 ;; 2.2: made sure that abbrev-mode was off in the ` *strokes*' buffer
|
|
|
214 ;; 2.2: added more dired advice for mouse permissions commands
|
|
|
215 ;; 2.2: added some checks to see if saving strokes is really necessary so
|
|
|
216 ;; the user doesn't get promped aimlessly.
|
|
|
217 ;; 2.2: change the `strokes-lift' symbol to a keyword of value `:strokes-lift'
|
|
|
218 ;; for legibility. IF YOUR OLD STROKES DON'T WORK, THIS IS PROBABLY WHY.
|
|
|
219 ;; 2.2: I might have to change this back to `'strokes-lift' because the keyword
|
|
|
220 ;; fails in emacs, though I don't know why.
|
|
|
221 ;; 2.2: `strokes-describe-stroke' is nicer during recursive edits
|
|
|
222 ;; 2.2: provided `strokes-fill-stroke' to fill in empty spaces of strokes
|
|
|
223 ;; as an important step towards platform (speed) independence.
|
|
|
224 ;; Because of this, I moved the global setting of `strokes-last-stroke'
|
|
|
225 ;; from `strokes-eliminate-consecutive-redundancies' to
|
|
|
226 ;; `strokes-fill-stroke' since the latter comes later in processing
|
|
|
227 ;; a user stroke.
|
|
|
228 ;; 2.2: Finally changed the defaults, so now `strokes-grid-resolution' is 9
|
|
|
229 ;; and `strokes-minimum-match-score' is 1000 by default. This will surely
|
|
|
230 ;; mess some people up, but if so, just set it back w/ M-x customize.
|
|
|
231 ;; 2.2: Fixed up the mechanism for updating the `strokes-window-configuration'.
|
|
|
232 ;; Now it only uses one function (`strokes-update-window-configuration')
|
|
|
233 ;; which does it all, and much more efficiently (thanks RMS!).
|
|
|
234 ;; 2.2 Fixed up the appearance of the *strokes* buffer so that there are no
|
|
|
235 ;; ugly line truncations, and I got rid of the bug which would draw the stroke
|
|
|
236 ;; on the wrong line. I still wish that `event-closest-point' was smarter.
|
|
|
237 ;; In fact, `event-closest-point' does *not* do what its name suggests.
|
|
|
238 ;; 2.3 Added more to `strokes-update-window-configuration' so it goes to hell less often
|
|
|
239 ;; 2.3 `strokes-mode' no longer will undefine keys unless it's sure that the user had
|
|
|
240 ;; had them mapped to a strokes command.
|
|
|
241 ;; 2.3 added more magic autoload statements so strokes work more smoothly.
|
|
|
242 ;; similarly, I made strokes-mode turn itself on when the user defines a stroke
|
|
|
243 ;; (thanks Hrvoje).
|
|
|
244 ;; 2.3 Added "Strokes" to the modeline when strokes is on, and allow toggling strokes
|
|
|
245 ;; with mouse button2.
|
|
|
246 ;; 2.3 Added `list-strokes', which is a really nice function which graphically lists
|
|
|
247 ;; all the strokes that the user has defined and their corresponding commands.
|
|
|
248 ;; `list-strokes' will appropriately colorize the pixmaps to display some time info.

|
|
1016 The strokes package allows you to define strokes (that you make with
|
|
|
1017 the mouse or other pointer device) that XEmacs can interpret as
|
|
|
1018 corresponding to commands, and then executes the commands. It does
|
|
|
1019 character recognition, so you don't have to worry about getting it
|
|
|
1020 right every time.
|
|
|
1021
|
|
|
1022 Strokes are easy to program and fun to use. To start strokes going,
|
|
|
1023 you'll want to put the following line in your .emacs file:
|
|
|
1024
|
|
|
1025 (and (fboundp 'device-on-window-system-p)
|
|
|
1026 (device-on-window-system-p)
|
|
|
1027 (require 'strokes))
|
|
|
1028
|
|
|
1029 This will load strokes when and only when you start XEmacs on a window
|
|
|
1030 system (i.e. that has a pointer (mouse) device, etc.).
|
|
|
1031
|
|
|
1032 To toggle strokes-mode, you just do
|
|
|
1033
|
|
|
1034 > M-x strokes-mode
|
|
|
1035
|
|
|
1036 When you're ready to start defining strokes, just use the command
|
|
|
1037
|
|
|
1038 > M-x global-set-stroke
|
|
|
1039
|
|
|
1040 You will see a ` *strokes*' buffer which is waiting for you to enter in
|
|
|
1041 your stroke. When you enter in the stroke, you draw with button1 or
|
|
|
1042 button2, and then end with button3. Next, you enter in the command
|
|
|
1043 which will be executed when that stroke is invoked. Simple as that.
|
|
|
1044 For now, try to define a stroke to copy a region. This is a popular
|
|
|
1045 edit command, so type
|
|
|
1046
|
|
|
1047 > M-x global-set-stroke
|
|
|
1048
|
|
|
1049 Then, in the ` *strokes*' buffer, draw the letter `C' (for `copy')
|
|
|
1050 and then, when it asks you to enter the command to map that to, type
|
|
|
1051
|
|
|
1052 > copy-region-as-kill
|
|
|
1053
|
|
|
1054 That's about as hard as it gets.
|
|
|
1055 Remember: paint with button1 or button2 and then end with button3.
|
|
|
1056
|
|
|
1057 If ever you want to know what a certain strokes maps to, then do
|
|
|
1058
|
|
|
1059 > M-x describe-stroke
|
|
|
1060
|
|
|
1061 and you can enter in any arbitrary stroke. Remember: The strokes
|
|
|
1062 package lets you program in simple and complex (multi-lift) strokes.
|
|
|
1063 The only difference is how you *invoke* the two. You will most likely
|
|
|
1064 use simple strokes, as complex strokes were developed for
|
|
|
1065 Chinese/Japanese/Korean. So the middle mouse button (button2) will
|
|
|
1066 invoke the command `strokes-do-stroke' in buffers where button2 doesn't
|
|
|
1067 already have a meaning other than its original, which is `mouse-yank'.
|
|
|
1068 But don't worry: `mouse-yank' will still work with strokes (see the
|
|
|
1069 variable `strokes-click-command').
|
|
|
1070
|
|
|
1071 If ever you define a stroke which you don't like, then you can unset
|
|
|
1072 it with the command
|
|
|
1073
|
|
|
1074 > M-x strokes-unset-last-stroke
|
|
|
1075
|
|
|
1076 You can always get an idea of what your current strokes look like with
|
|
|
1077 the command
|
|
|
1078
|
|
|
1079 > M-x list-strokes
|
|
|
1080
|
|
|
1081 Your strokes will be displayed in from most recent down, and the
|
|
|
1082 beginning of each simple stroke will be marked by a color dot. Since
|
|
|
1083 you may have several simple strokes in a complex stroke, the dot
|
|
|
1084 colors are arranged in the rainbow color sequence, `ROYGBIV'.
|
|
|
1085
|
|
|
1086 Your strokes are stored as you enter them. They get saved in a file
|
|
|
1087 called ~/.strokes, along with other strokes configuration variables.
|
|
|
1088 You can change this location by setting the variable `strokes-file'.
|
|
|
1089 You will be prompted to save them when you exit XEmacs, or you can save
|
|
|
1090 them with
|
|
|
1091
|
|
|
1092 > M-x save-strokes
|
|
|
1093
|
|
|
1094 Your strokes get loaded automatically when you enable `strokes-mode'.
|
|
|
1095 You can also load in your user-defined strokes with
|
|
|
1096
|
|
|
1097 > M-x load-user-strokes
|
|
|
1098
|
|
|
1099 A few more important things:
|
|
|
1100
|
|
|
1101 o The command `strokes-do-stroke' is also invoked with C-button2, so that you
|
|
|
1102 can still enter a stroke in modes which use button2 for other things,
|
|
|
1103 such as cross-referencing.
|
|
|
1104
|
|
|
1105 o Complex strokes (i.e. `strokes-do-complex-stroke'), by default, use
|
|
|
1106 Sh-button2.
|
|
|
1107
|
|
|
1108 o Strokes are a bit computer-dependent in that they depend somewhat on
|
|
|
1109 the speed of the computer you're working on. This means that you
|
|
|
1110 may have to tweak some variables. You can read about them in the
|
|
|
1111 commentary of `strokes.el'. Better to just use apropos and read their
|
|
|
1112 docstrings. All variables/functions start with `strokes'. The one
|
|
|
1113 variable which many people wanted to see was
|
|
|
1114 `strokes-use-strokes-buffer' which allows the user to use strokes
|
|
|
1115 silently--without displaying the strokes. All variables can be set
|
|
|
1116 by customizing the group named `strokes' via the customization package:
|
|
|
1117
|
|
|
1118 > M-x customize
|
|
|
1119
|
|
|
1120 o A problem with strokes happens when you resize windows. If you
|
|
|
1121 enlarge your XEmacs window a lot and realize that your strokes
|
|
|
1122 buffer is not big enough, you may need to fix it with
|
|
|
1123
|
|
|
