66 | doc: /* Specify a way of parsing arguments for interactive use of a function. |
67 | For example, write | |
68 | (defun foo (arg) "Doc string" (interactive "p") ...use arg...) | |
69 | to make ARG be the prefix argument when `foo' is called as a command. | |
70 | The "call" to `interactive' is actually a declaration rather than a function; | |
71 | it tells `call-interactively' how to read arguments | |
72 | to pass to the function. | |
73 | When actually called, `interactive' just returns nil. | |
74 | ||
75 | The argument of `interactive' is usually a string containing a code letter | |
76 | followed by a prompt. (Some code letters do not use I/O to get | |
77 | the argument and do not need prompts.) To prompt for multiple arguments, | |
78 | give a code letter, its prompt, a newline, and another code letter, etc. | |
79 | Prompts are passed to format, and may use % escapes to print the | |
80 | arguments that have already been read. | |
81 | If the argument is not a string, it is evaluated to get a list of | |
82 | arguments to pass to the function. | |
83 | Just `(interactive)' means pass no args when calling interactively. | |
84 | ||
85 | Code letters available are: | |
86 | a -- Function name: symbol with a function definition. | |
87 | b -- Name of existing buffer. | |
88 | B -- Name of buffer, possibly nonexistent. | |
89 | c -- Character (no input method is used). | |
90 | C -- Command name: symbol with interactive function definition. | |
91 | d -- Value of point as number. Does not do I/O. | |
92 | D -- Directory name. | |
93 | e -- Parametrized event (i.e., one that's a list) that invoked this command. | |
94 | If used more than once, the Nth `e' returns the Nth parameterized event. | |
95 | This skips events that are integers or symbols. | |
96 | f -- Existing file name. | |
97 | F -- Possibly nonexistent file name. | |
75f9fbe8 | 98 | G -- Possibly nonexistent file name, defaulting to just directory name. |
fdb82f93 PJ |
99 | i -- Ignored, i.e. always nil. Does not do I/O. |
100 | k -- Key sequence (downcase the last event if needed to get a definition). | |
101 | K -- Key sequence to be redefined (do not downcase the last event). | |
102 | m -- Value of mark as number. Does not do I/O. | |
103 | M -- Any string. Inherits the current input method. | |
104 | n -- Number read using minibuffer. | |
425b457e | 105 | N -- Numeric prefix arg, or if none, do like code `n'. |
fdb82f93 PJ |
106 | p -- Prefix arg converted to number. Does not do I/O. |
107 | P -- Prefix arg in raw form. Does not do I/O. | |
108 | r -- Region: point and mark as 2 numeric args, smallest first. Does no I/O. | |
109 | s -- Any string. Does not inherit the current input method. | |
110 | S -- Any symbol. | |
39900c4e | 111 | U -- Mouse up event discarded by a previous k or K argument. |
fdb82f93 PJ |
112 | v -- Variable name: symbol that is user-variable-p. |
113 | x -- Lisp expression read but not evaluated. | |
114 | X -- Lisp expression read and evaluated. | |
115 | z -- Coding system. | |
116 | Z -- Coding system, nil if no prefix arg. | |
117 | In addition, if the string begins with `*' | |
118 | then an error is signaled if the buffer is read-only. | |
119 | This happens before reading any arguments. | |
120 | If the string begins with `@', then Emacs searches the key sequence | |
121 | which invoked the command for its first mouse click (or any other | |
122 | event which specifies a window), and selects that window before | |
123 | reading any arguments. You may use both `@' and `*'; they are | |
84cc45a7 PJ |
124 | processed in the order that they appear. |
