27 | ;; For those who are annoyed by the mouse pointer obscuring text, |
28 | ;; this mode moves the mouse pointer - either just a little out of | |
187bd11c | 29 | ;; the way, or all the way to the corner of the frame. |
b578f267 | 30 | ;; To use, load or evaluate this file and type M-x mouse-avoidance-mode . |
187bd11c | 31 | ;; To set up permanently, put the following in your .emacs: |
b578f267 | 32 | ;; |
95d059bd | 33 | ;; (if (display-mouse-p) (mouse-avoidance-mode 'animate)) |
b578f267 | 34 | ;; |
8557ea06 RS |
35 | ;; Other legitimate alternatives include |
36 | ;; `banish', `exile', `jump', `cat-and-mouse', and `proteus'. | |
37 | ;; They do somewhat different things. | |
b578f267 EN |
38 | ;; See the documentation for function `mouse-avoidance-mode' for |
39 | ;; details of the different modes. | |
40 | ;; | |
41 | ;; For added silliness, make the animatee animate... | |
42 | ;; put something similar to the following into your .emacs: | |
43 | ;; | |
95d059bd | 44 | ;; (if (eq window-system 'x) |
b578f267 EN |
45 | ;; (mouse-avoidance-set-pointer-shape |
46 | ;; (eval (nth (random 4) | |
47 | ;; '(x-pointer-man x-pointer-spider | |
48 | ;; x-pointer-gobbler x-pointer-gumby))))) | |
49 | ;; | |
50 | ;; For completely random pointer shape, replace the setq above with: | |
51 | ;; (setq x-pointer-shape (mouse-avoidance-random-shape)) | |
187bd11c | 52 | ;; |
b578f267 EN |
53 | ;; Bugs / Warnings / To-Do: |
54 | ;; | |
55 | ;; - Using this code does slow emacs down. "banish" mode shouldn't | |
56 | ;; be too bad, and on my workstation even "animate" is reasonable. | |
57 | ;; | |
58 | ;; - It ought to find out where any overlapping frames are and avoid them, | |
59 | ;; rather than always raising the frame. | |
60 | ||
61 | ;; Credits: | |
187bd11c | 62 | ;; This code was helped by all those who contributed suggestions, |
b578f267 EN |
63 | ;; fixes, and additions |
64 | ;; Joe Harrington (and his advisor), for the original inspiration. | |
65 | ;; Ken Manheimer, for dreaming up the Protean mode. | |
66 | ;; Richard Stallman, for the awful cat-and-mouse pun, among other things. | |
67 | ;; Mike Williams, Denis Howe, Bill Benedetto, Chris Moore, Don Morris, | |
68 | ;; Simon Marshall, and M.S. Ashton, for their feedback. | |
