89 the function is an interactive command! |
| 428 | 90 When actually called, `interactive' just returns nil. |
| 91 | |
| 92 The argument of `interactive' is usually a string containing a code letter | |
| 93 followed by a prompt. (Some code letters do not use I/O to get | |
| 94 the argument and do not need prompts.) To prompt for multiple arguments, | |
| 95 give a code letter, its prompt, a newline, and another code letter, etc. | |
| 96 Prompts are passed to format, and may use % escapes to print the | |
| 97 arguments that have already been read. | |
| 98 If the argument is not a string, it is evaluated to get a list of | |
| 99 arguments to pass to the function. | |
| 100 Just `(interactive)' means pass no args when calling interactively. | |
| 101 | |
| 102 Code letters available are: | |
| 103 a -- Function name: symbol with a function definition. | |
| 104 b -- Name of existing buffer. | |
| 105 B -- Name of buffer, possibly nonexistent. | |
| 106 c -- Character. | |
| 107 C -- Command name: symbol with interactive function definition. | |
| 108 d -- Value of point as number. Does not do I/O. | |
| 109 D -- Directory name. | |
| 110 e -- Last mouse-button or misc-user event that invoked this command. | |
| 111 If used more than once, the Nth `e' returns the Nth such event. | |
| 112 Does not do I/O. | |
| 113 f -- Existing file name. | |
| 114 F -- Possibly nonexistent file name. | |
| 115 i -- Always nil, ignore. Use to skip arguments when interactive. | |
| 116 k -- Key sequence (a vector of events). | |
| 117 K -- Key sequence to be redefined (do not automatically down-case). | |
| 118 m -- Value of mark as number. Does not do I/O. | |
| 119 n -- Number read using minibuffer. | |
| 120 N -- Prefix arg converted to number, or if none, do like code `n'. | |
| 121 p -- Prefix arg converted to number. Does not do I/O. | |
| 122 P -- Prefix arg in raw form. Does not do I/O. | |
| 123 r -- Region: point and mark as 2 numeric args, smallest first. Does no I/O. | |
| 124 s -- Any string. | |
| 125 S -- Any symbol. | |
| 126 v -- Variable name: symbol that is user-variable-p. | |
| 127 x -- Lisp expression read but not evaluated. | |
| 128 X -- Lisp expression read and evaluated. | |
| 129 z -- Coding system. (Always nil if no Mule support.) | |
| 130 Z -- Coding system, nil if no prefix arg. (Always nil if no Mule support.) | |
| 131 In addition, if the string begins with `*' | |
| 132 then an error is signaled if the buffer is read-only. | |
| 133 This happens before reading any arguments. | |
| 134 If the string begins with `@', then the window the mouse is over is selected | |
| 135 before anything else is done. | |
| 136 If the string begins with `_', then this command will not cause the region | |
| 137 to be deactivated when it completes; that is, `zmacs-region-stays' will be | |
| 138 set to t when the command exits successfully. | |
| 139 You may use any of `@', `*' and `_' at the beginning of the string; | |
| 140 they are processed in the order that they appear. | |
| 502 | 141 |
| 142 | |
| 143 When writing your own interactive spec, it can be useful to know the | |
| 144 equivalent Lisp expressions for the various code letters. They are: | |
| 145 | |
| 146 a -- (read-function "PROMPT") | |
| 147 b -- (let ((def (current-buffer))) | |
| 148 (if (eq (selected-window) (active-minibuffer-window)) | |
