| 32 ;; |A minor mode replacement for isearch.el. | |
| 33 | |
| 34 ;;==================================================================== | |
| 35 ;; Instructions | |
| 36 | |
| 37 ;; Searching with isearch-mode.el should work just like isearch.el, | |
| 38 ;; except it is done in a temporary minor mode that terminates when | |
| 39 ;; you finish searching. | |
| 40 | |
| 41 ;; Semi-modal searching is supported, using a recursive edit. If | |
| 42 ;; isearching is started non-interactively by calling one of the | |
| 43 ;; isearch commands (e.g. (isearch-forward), but not like gnus does | |
| 44 ;; it: (call-interactively 'isearch-forward)), isearch-mode does not | |
| 45 ;; return until the search is completed. You should still be able | |
| 46 ;; switch buffers, so be careful not to get things confused. | |
| 47 | |
| 48 ;; The key bindings active within isearch-mode are defined below in | |
| 49 ;; `isearch-mode-map' which is given bindings close to the default | |
| 50 ;; characters of isearch.el for version 19. With `isearch-mode', | |
| 51 ;; however, you can bind multi-character keys and it should be easier | |
| 52 ;; to add new commands. One bug though: keys with meta-prefix cannot | |
| 53 ;; be longer than two chars. Also see minibuffer-local-isearch-map | |
| 54 ;; for bindings active during `isearch-edit-string'. | |
| 55 | |
| 56 ;; The search ring and completion commands automatically put you in | |
| 57 ;; the minibuffer to edit the string. This gives you a chance to | |
| 58 ;; modify the search string before executing the search. There are | |
| 59 ;; three commands to terminate the editing: C-s and C-r exit the | |
| 60 ;; minibuffer and search forward and reverse respectively, while C-m | |
| 61 ;; exits and does a nonincremental search. | |
| 62 | |
| 63 ;; Exiting immediately from isearch uses isearch-edit-string instead | |
| 64 ;; of nonincremental-search, if search-nonincremental-instead is non-nil. | |
| 65 ;; The name of this option should probably be changed if we decide to | |
| 66 ;; keep the behavior. One difference is that isearch-edit-string does | |
| 67 ;; not support word search yet; perhaps isearch-mode should support it | |
| 68 ;; even for incremental searches, but how? | |

| 77 ;; | |
| 78 ;; Revision 1.3 92/06/29 13:10:08 liberte | |
| 79 ;; Moved modal isearch-mode handling into isearch-mode. | |
| 80 ;; Got rid of buffer-local isearch variables. | |
| 81 ;; isearch-edit-string used by ring adjustments, completion, and | |
| 82 ;; nonincremental searching. C-s and C-r are additional exit commands. | |
| 83 ;; Renamed all regex to regexp. | |
| 84 ;; Got rid of found-start and found-point globals. | |
| 85 ;; Generalized handling of upper-case chars. | |
| 86 | |
| 87 ;; Revision 1.2 92/05/27 11:33:57 liberte | |
| 88 ;; Emacs version 19 has a search ring, which is supported here. | |
| 89 ;; Other fixes found in the version 19 isearch are included here. | |
| 90 ;; | |
| 91 ;; Also see variables search-caps-disable-folding, | |
| 92 ;; search-nonincremental-instead, search-whitespace-regexp, and | |
| 93 ;; commands isearch-toggle-regexp, isearch-edit-string. | |
| 94 ;; | |
| 95 ;; semi-modal isearching is supported. | |
| 96 | |
| 97 ;; Changes for 1.1 | |
| 98 ;; 3/18/92 Fixed invalid-regexp. | |
| 99 ;; 3/18/92 Fixed yanking in regexps. | |
