60 | DEFUN ("interactive", Ffoo, Sfoo, 0, 0, 0, | |
61 | "Specify a way of parsing arguments for interactive use of a function.\n\ | |
62 | For example, write\n\ | |
63 | (defun foo (arg) \"Doc string\" (interactive \"p\") ...use arg...)\n\ | |
64 | to make ARG be the prefix argument when `foo' is called as a command.\n\ | |
65 | The \"call\" to `interactive' is actually a declaration rather than a function;\n\ | |
66 | it tells `call-interactively' how to read arguments\n\ | |
67 | to pass to the function.\n\ | |
68 | When actually called, `interactive' just returns nil.\n\ | |
69 | \n\ | |
70 | The argument of `interactive' is usually a string containing a code letter\n\ | |
71 | followed by a prompt. (Some code letters do not use I/O to get\n\ | |
72 | the argument and do not need prompts.) To prompt for multiple arguments,\n\ | |
73 | give a code letter, its prompt, a newline, and another code letter, etc.\n\ | |
74 | Prompts are passed to format, and may use % escapes to print the\n\ | |
75 | arguments that have already been read.\n\ | |
76 | If the argument is not a string, it is evaluated to get a list of\n\ | |
77 | arguments to pass to the function.\n\ | |
78 | Just `(interactive)' means pass no args when calling interactively.\n\ | |
79 | \nCode letters available are:\n\ | |
80 | a -- Function name: symbol with a function definition.\n\ | |
81 | b -- Name of existing buffer.\n\ | |
82 | B -- Name of buffer, possibly nonexistent.\n\ | |
83 | c -- Character.\n\ | |
84 | C -- Command name: symbol with interactive function definition.\n\ | |
85 | d -- Value of point as number. Does not do I/O.\n\ | |
86 | D -- Directory name.\n\ | |
4d1f43c0 RS |
87 | e -- Parametrized event (i.e., one that's a list) that invoked this command.\n\ |
88 | If used more than once, the Nth `e' returns the Nth parameterized event.\n\ | |
89 | This skips events that are integers or symbols.\n\ | |
ec28a64d MB |
90 | f -- Existing file name.\n\ |
91 | F -- Possibly nonexistent file name.\n\ | |
b631003b RS |
92 | k -- Key sequence (downcase the last event if needed to get a definition).\n\ |
93 | K -- Key sequence to be redefined (do not downcase the last event).\n\ | |
ec28a64d MB |
94 | m -- Value of mark as number. Does not do I/O.\n\ |
95 | n -- Number read using minibuffer.\n\ | |
701ca6c0 | 96 | N -- Raw prefix arg, or if none, do like code `n'.\n\ |
ec28a64d MB |
97 | p -- Prefix arg converted to number. Does not do I/O.\n\ |
98 | P -- Prefix arg in raw form. Does not do I/O.\n\ | |
99 | r -- Region: point and mark as 2 numeric args, smallest first. Does no I/O.\n\ | |
100 | s -- Any string.\n\ | |
101 | S -- Any symbol.\n\ | |
102 | v -- Variable name: symbol that is user-variable-p.\n\ | |
103 | x -- Lisp expression read but not evaluated.\n\ | |
104 | X -- Lisp expression read and evaluated.\n\ | |
105 | In addition, if the string begins with `*'\n\ | |
106 | then an error is signaled if the buffer is read-only.\n\ | |
107 | This happens before reading any arguments.\n\ | |
dbc4e1c1 JB |
108 | If the string begins with `@', then Emacs searches the key sequence\n\ |
109 | which invoked the command for its first mouse click (or any other\n\ | |
110 | event which specifies a window), and selects that window before\n\ | |
111 | reading any arguments. You may use both `@' and `*'; they are\n\ | |
112 | processed in the order that they appear." */ | |
