70 | doc: /* Specify a way of parsing arguments for interactive use of a function. |
71 | For example, write | |
72 | (defun foo (arg) "Doc string" (interactive "p") ...use arg...) | |
73 | to make ARG be the prefix argument when `foo' is called as a command. | |
74 | The "call" to `interactive' is actually a declaration rather than a function; | |
75 | it tells `call-interactively' how to read arguments | |
76 | to pass to the function. | |
77 | When actually called, `interactive' just returns nil. | |
78 | ||
79 | The argument of `interactive' is usually a string containing a code letter | |
80 | followed by a prompt. (Some code letters do not use I/O to get | |
81 | the argument and do not need prompts.) To prompt for multiple arguments, | |
82 | give a code letter, its prompt, a newline, and another code letter, etc. | |
83 | Prompts are passed to format, and may use % escapes to print the | |
84 | arguments that have already been read. | |
85 | If the argument is not a string, it is evaluated to get a list of | |
86 | arguments to pass to the function. | |
87 | Just `(interactive)' means pass no args when calling interactively. | |
88 | ||
89 | Code letters available are: | |
90 | a -- Function name: symbol with a function definition. | |
91 | b -- Name of existing buffer. | |
92 | B -- Name of buffer, possibly nonexistent. | |
93 | c -- Character (no input method is used). | |
94 | C -- Command name: symbol with interactive function definition. | |
95 | d -- Value of point as number. Does not do I/O. | |
96 | D -- Directory name. | |
97 | e -- Parametrized event (i.e., one that's a list) that invoked this command. | |
98 | If used more than once, the Nth `e' returns the Nth parameterized event. | |
99 | This skips events that are integers or symbols. | |
100 | f -- Existing file name. | |
101 | F -- Possibly nonexistent file name. | |
75f9fbe8 | 102 | G -- Possibly nonexistent file name, defaulting to just directory name. |
fdb82f93 PJ |
103 | i -- Ignored, i.e. always nil. Does not do I/O. |
104 | k -- Key sequence (downcase the last event if needed to get a definition). | |
105 | K -- Key sequence to be redefined (do not downcase the last event). | |
106 | m -- Value of mark as number. Does not do I/O. | |
107 | M -- Any string. Inherits the current input method. | |
108 | n -- Number read using minibuffer. | |
425b457e | 109 | N -- Numeric prefix arg, or if none, do like code `n'. |
fdb82f93 PJ |
110 | p -- Prefix arg converted to number. Does not do I/O. |
111 | P -- Prefix arg in raw form. Does not do I/O. | |
112 | r -- Region: point and mark as 2 numeric args, smallest first. Does no I/O. | |
113 | s -- Any string. Does not inherit the current input method. | |
114 | S -- Any symbol. | |
39900c4e | 115 | U -- Mouse up event discarded by a previous k or K argument. |
fdb82f93 PJ |
116 | v -- Variable name: symbol that is user-variable-p. |
117 | x -- Lisp expression read but not evaluated. | |
118 | X -- Lisp expression read and evaluated. | |
119 | z -- Coding system. | |
120 | Z -- Coding system, nil if no prefix arg. | |
9bdb1538 CY |
121 | |
122 | In addition, if the string begins with `*', an error is signaled if | |
123 | the buffer is read-only. | |
124 | If the string begins with `@', Emacs searches the key sequence which | |
125 | invoked the command for its first mouse click (or any other event | |
126 | which specifies a window). | |
127 | If the string begins with `^' and `shift-select-mode' is non-nil, | |
128 | Emacs first calls the function `handle-shift-select'. | |
129 | You may use `@', `*', and `^' together. They are processed in the | |
130 | order that they appear, before reading any arguments. | |
