+ − 82 Specify a way of parsing arguments for interactive use of a function.
+ − 83 For example, write
+ − 84 (defun foo (arg) "Doc string" (interactive "p") ...use arg...)
+ − 85 to make ARG be the prefix argument when `foo' is called as a command.
+ − 86 The "call" to `interactive' is actually a declaration rather than a function;
+ − 87 it tells `call-interactively' how to read arguments
+ − 88 to pass to the function.
+ − 89 When actually called, `interactive' just returns nil.
+ − 90
+ − 91 The argument of `interactive' is usually a string containing a code letter
+ − 92 followed by a prompt. (Some code letters do not use I/O to get
+ − 93 the argument and do not need prompts.) To prompt for multiple arguments,
+ − 94 give a code letter, its prompt, a newline, and another code letter, etc.
+ − 95 Prompts are passed to format, and may use % escapes to print the
+ − 96 arguments that have already been read.
+ − 97 If the argument is not a string, it is evaluated to get a list of
+ − 98 arguments to pass to the function.
+ − 99 Just `(interactive)' means pass no args when calling interactively.
+ − 100
+ − 101 Code letters available are:
+ − 102 a -- Function name: symbol with a function definition.
+ − 103 b -- Name of existing buffer.
+ − 104 B -- Name of buffer, possibly nonexistent.
+ − 105 c -- Character.
+ − 106 C -- Command name: symbol with interactive function definition.
+ − 107 d -- Value of point as number. Does not do I/O.
+ − 108 D -- Directory name.
+ − 109 e -- Last mouse-button or misc-user event that invoked this command.
+ − 110 If used more than once, the Nth `e' returns the Nth such event.
+ − 111 Does not do I/O.
+ − 112 f -- Existing file name.
+ − 113 F -- Possibly nonexistent file name.
+ − 114 i -- Always nil, ignore. Use to skip arguments when interactive.
+ − 115 k -- Key sequence (a vector of events).
+ − 116 K -- Key sequence to be redefined (do not automatically down-case).
+ − 117 m -- Value of mark as number. Does not do I/O.
+ − 118 n -- Number read using minibuffer.
+ − 119 N -- Prefix arg converted to number, or if none, do like code `n'.
+ − 120 p -- Prefix arg converted to number. Does not do I/O.
+ − 121 P -- Prefix arg in raw form. Does not do I/O.
+ − 122 r -- Region: point and mark as 2 numeric args, smallest first. Does no I/O.
+ − 123 s -- Any string.
+ − 124 S -- Any symbol.
+ − 125 v -- Variable name: symbol that is user-variable-p.
+ − 126 x -- Lisp expression read but not evaluated.
+ − 127 X -- Lisp expression read and evaluated.
+ − 128 z -- Coding system. (Always nil if no Mule support.)
+ − 129 Z -- Coding system, nil if no prefix arg. (Always nil if no Mule support.)
+ − 130 In addition, if the string begins with `*'
+ − 131 then an error is signaled if the buffer is read-only.
+ − 132 This happens before reading any arguments.
+ − 133 If the string begins with `@', then the window the mouse is over is selected
+ − 134 before anything else is done.
+ − 135 If the string begins with `_', then this command will not cause the region
+ − 136 to be deactivated when it completes; that is, `zmacs-region-stays' will be
+ − 137 set to t when the command exits successfully.
+ − 138 You may use any of `@', `*' and `_' at the beginning of the string;
+ − 139 they are processed in the order that they appear.
