62 "Specify a way of parsing arguments for interactive use of a function.\n\
64 (defun foo (arg) \"Doc string\" (interactive \"p\") ...use arg...)\n\
65 to make ARG be the prefix argument when `foo' is called as a command.\n\
66 The \"call\" to `interactive' is actually a declaration rather than a function;\n\
67 it tells `call-interactively' how to read arguments\n\
68 to pass to the function.\n\
69 When actually called, `interactive' just returns nil.\n\
71 The argument of `interactive' is usually a string containing a code letter\n\
72 followed by a prompt. (Some code letters do not use I/O to get\n\
73 the argument and do not need prompts.) To prompt for multiple arguments,\n\
74 give a code letter, its prompt, a newline, and another code letter, etc.\n\
75 Prompts are passed to format, and may use % escapes to print the\n\
76 arguments that have already been read.\n\
77 If the argument is not a string, it is evaluated to get a list of\n\
78 arguments to pass to the function.\n\
79 Just `(interactive)' means pass no args when calling interactively.\n\
80 \nCode letters available are:\n\
81 a -- Function name: symbol with a function definition.\n\
82 b -- Name of existing buffer.\n\
83 B -- Name of buffer, possibly nonexistent.\n\
85 C -- Command name: symbol with interactive function definition.\n\
86 d -- Value of point as number. Does not do I/O.\n\
87 D -- Directory name.\n\
88 e -- Parametrized event (i.e., one that's a list) that invoked this command.\n\
89 If used more than once, the Nth `e' returns the Nth parameterized event.\n\
90 This skips events that are integers or symbols.\n\
91 f -- Existing file name.\n\
92 F -- Possibly nonexistent file name.\n\
93 k -- Key sequence (downcase the last event if needed to get a definition).\n\
94 K -- Key sequence to be redefined (do not downcase the last event).\n\
95 m -- Value of mark as number. Does not do I/O.\n\
96 n -- Number read using minibuffer.\n\
97 N -- Raw prefix arg, or if none, do like code `n'.\n\
98 p -- Prefix arg converted to number. Does not do I/O.\n\
99 P -- Prefix arg in raw form. Does not do I/O.\n\
100 r -- Region: point and mark as 2 numeric args, smallest first. Does no I/O.\n\
103 v -- Variable name: symbol that is user-variable-p.\n\
104 x -- Lisp expression read but not evaluated.\n\
105 X -- Lisp expression read and evaluated.\n\
106 In addition, if the string begins with `*'\n\
107 then an error is signaled if the buffer is read-only.\n\
108 This happens before reading any arguments.\n\
109 If the string begins with `@', then Emacs searches the key sequence\n\
110 which invoked the command for its first mouse click (or any other\n\
111 event which specifies a window), and selects that window before\n\
112 reading any arguments. You may use both `@' and `*'; they are\n\
113 processed in the order that they appear." */
