53 | doc: /* Specify a way of parsing arguments for interactive use of a function. |
54 | For example, write | |
f9257eed AM |
55 | (defun foo (arg buf) "Doc string" (interactive "P\\nbbuffer: ") .... ) |
56 | to make ARG be the raw prefix argument, and set BUF to an existing buffer, | |
57 | when `foo' is called as a command. | |
fdb82f93 PJ |
58 | The "call" to `interactive' is actually a declaration rather than a function; |
59 | it tells `call-interactively' how to read arguments | |
60 | to pass to the function. | |
61 | When actually called, `interactive' just returns nil. | |
62 | ||
f9257eed AM |
63 | Usually the argument of `interactive' is a string containing a code letter |
64 | followed optionally by a prompt. (Some code letters do not use I/O to get | |
65 | the argument and do not use prompts.) To get several arguments, concatenate | |
66 | the individual strings, separating them by newline characters. | |
67 | Prompts are passed to format, and may use % escapes to print the | |
fdb82f93 PJ |
68 | arguments that have already been read. |
69 | If the argument is not a string, it is evaluated to get a list of | |
70 | arguments to pass to the function. | |
71 | Just `(interactive)' means pass no args when calling interactively. | |
72 | ||
73 | Code letters available are: | |
74 | a -- Function name: symbol with a function definition. | |
75 | b -- Name of existing buffer. | |
76 | B -- Name of buffer, possibly nonexistent. | |
77 | c -- Character (no input method is used). | |
78 | C -- Command name: symbol with interactive function definition. | |
79 | d -- Value of point as number. Does not do I/O. | |
80 | D -- Directory name. | |
e4920bc9 | 81 | e -- Parameterized event (i.e., one that's a list) that invoked this command. |
fdb82f93 PJ |
82 | If used more than once, the Nth `e' returns the Nth parameterized event. |
83 | This skips events that are integers or symbols. | |
84 | f -- Existing file name. | |
85 | F -- Possibly nonexistent file name. | |
75f9fbe8 | 86 | G -- Possibly nonexistent file name, defaulting to just directory name. |
fdb82f93 PJ |
87 | i -- Ignored, i.e. always nil. Does not do I/O. |
88 | k -- Key sequence (downcase the last event if needed to get a definition). | |
89 | K -- Key sequence to be redefined (do not downcase the last event). | |
90 | m -- Value of mark as number. Does not do I/O. | |
91 | M -- Any string. Inherits the current input method. | |
92 | n -- Number read using minibuffer. | |
425b457e | 93 | N -- Numeric prefix arg, or if none, do like code `n'. |
fdb82f93 PJ |
94 | p -- Prefix arg converted to number. Does not do I/O. |
95 | P -- Prefix arg in raw form. Does not do I/O. | |
96 | r -- Region: point and mark as 2 numeric args, smallest first. Does no I/O. | |
97 | s -- Any string. Does not inherit the current input method. | |
98 | S -- Any symbol. | |
39900c4e | 99 | U -- Mouse up event discarded by a previous k or K argument. |
b4d3bc10 | 100 | v -- Variable name: symbol that is `custom-variable-p'. |
fdb82f93 PJ |
101 | x -- Lisp expression read but not evaluated. |
102 | X -- Lisp expression read and evaluated. | |
103 | z -- Coding system. | |
104 | Z -- Coding system, nil if no prefix arg. | |
9bdb1538 CY |
105 | |
106 | In addition, if the string begins with `*', an error is signaled if | |
107 | the buffer is read-only. | |
1e49bfab LMI |
108 | If `@' appears at the beginning of the string, and if the key sequence |
109 | used to invoke the command includes any mouse events, then the window | |
110 | associated with the first of those events is selected before the | |
111 | command is run. | |
9bdb1538 | 112 | If the string begins with `^' and `shift-select-mode' is non-nil, |
2a4f8d3d | 113 | Emacs first calls the function `handle-shift-selection'. |
9bdb1538 CY |
114 | You may use `@', `*', and `^' together. They are processed in the |
115 | order that they appear, before reading any arguments. | |
