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

|
|

145 equivalent Lisp expressions for the various code letters. They are:
