112 | ;;;; EDT Emulation Commands | |
113 | ;;;; | |
114 | ||
115 | ;;; Almost all of EDT's keypad mode commands have equivalent | |
116 | ;;; counterparts in Emacs. Some behave the same way in Emacs as they | |
117 | ;;; do in EDT, but most do not. | |
118 | ;;; | |
119 | ;;; The following Emacs functions emulate, where practical, the exact | |
120 | ;;; behavior of the corresponding EDT keypad mode commands. In a few | |
121 | ;;; cases, the emulation is not exact, but it is close enough for most | |
122 | ;;; EDT die-hards. | |
123 | ;;; | |
124 | ;;; In a very few cases, we chose to use the superior Emacs way of | |
125 | ;;; handling things. For example, we do not emulate the EDT SUBS | |
126 | ;;; command. Instead, we chose to use the superior Emacs | |
127 | ;;; query-replace function. | |
128 | ;;; | |
129 | ||
130 | ;;; | |
131 | ;;; PAGE | |
132 | ;;; | |
133 | ;;; Emacs uses the regexp assigned to page-delimiter to determine what | |
134 | ;;; marks a page break. This is normally "^\f", which causes the | |
135 | ;;; edt-page command to ignore form feeds not located at the beginning | |
136 | ;;; of a line. To emulate the EDT PAGE command exactly, | |
137 | ;;; page-delimiter is set to "\f" when EDT emulation is turned on, and | |
138 | ;;; restored to its original value when EDT emulation is turned off. | |
139 | ;;; But this can be overridden if the EDT definition is not desired by | |
140 | ;;; placing | |
141 | ;;; | |
142 | ;;; (setq edt-keep-current-page-delimiter t) | |
143 | ;;; | |
144 | ;;; in your .emacs file. | |
