32 | ;;; Several new commands and features have been added. Emacs version | |
33 | ;;; 19 has a search ring, which is supported here. Other fixes found | |
34 | ;;; in the version 19 isearch are included here. Also see variables | |
35 | ;;; search-caps-disable-folding, search-nonincremental-instead, | |
36 | ;;; search-whitespace-regexp, and commands isearch-toggle-regexp, | |
37 | ;;; isearch-edit-string, | |
38 | ;;; | |
39 | ;;; Semi-modal searching is supported, using a recursive edit. If | |
40 | ;;; isearching is started non-interactively by calling one of the | |
41 | ;;; isearch commands (e.g. isearch-forward), it does not return | |
42 | ;;; until the search is completed. You should still be able switch | |
43 | ;;; buffers, so be careful not to get things confused. | |
44 | ;;; | |
45 | ||
46 | ;;; Changes for 1.1 | |
47 | ;;; 3/18/92 Fixed invalid-regexp. | |
48 | ;;; 3/18/92 Fixed yanking in regexps. | |

51 | ;; Instructions | |
52 | ||
53 | ;; Searching with isearch-mode.el should work just like isearch.el, | |
54 | ;; except it is done in a temporary minor mode that terminates when | |
55 | ;; you finish searching. | |
56 | ||
57 | ;; To use isearch-mode instead of the standard isearch.el, add the | |
58 | ;; following to your .emacs file. The standard key bindings to | |
59 | ;; isearch-forward, etc, will then use isearch-mode instead of | |
60 | ;; isearch. | |
61 | ||
62 | ;; (fset 'isearch 'isearch-mode) | |
63 | ;; (autoload 'isearch-mode "isearch-mode") | |
64 | ||
65 | ;; The key bindings active within isearch-mode are defined below in | |
66 | ;; `isearch-mode-map' and `isearch-mode-meta-map' which are given | |
67 | ;; bindings close to the default characters of isearch.el for | |
68 | ;; version 19. With `isearch-mode', however, you can bind | |
69 | ;; multi-character keys and it should be easier to add new commands. | |
70 | ||
71 | ;; Note to epoch and emacs version 19 users: isearch-mode should | |
72 | ;; work even if you switch windows with the mouse. However, if | |
73 | ;; you isearch in a buffer that is also displayed in another window, | |
74 | ;; when you switch to that other window you will still be in | |
75 | ;; isearch mode but not necessarily in the right state for it to work. | |
76 | ;; So ... don't do it unless you are in an experimental mood. | |
77 | ;; You can also experiment with the window-local-variable routines | |
78 | ;; contained in this package but not yet used. | |
79 | ;; Also, I am not sure what happens when you return to an isearching | |
80 | ;; buffer; ideally, the echo area should redisplay the searching status. | |
81 | ;; A select-window-hook might be useful. | |
