21.15 Minibuffer Miscellany

Function: minibufferp &optional buffer-or-name live

This function returns non-nil if buffer-or-name is a minibuffer. If buffer-or-name is omitted or nil, it tests the current buffer. When live is non-nil, the function returns non-nil only when buffer-or-name is an active minibuffer.

Variable: minibuffer-setup-hook

This is a normal hook that is run whenever a minibuffer is entered. See Hooks.

Macro: minibuffer-with-setup-hook function &rest body

This macro executes body after arranging for the specified function to be called via minibuffer-setup-hook. By default, function is called before the other functions in the minibuffer-setup-hook list, but if function is of the form (:append func), func will be called after the other hook functions.

The body forms should not use the minibuffer more than once. If the minibuffer is re-entered recursively, function will only be called once, for the outermost use of the minibuffer.

Variable: minibuffer-exit-hook

This is a normal hook that is run whenever a minibuffer is exited. See Hooks.

Variable: minibuffer-help-form

The current value of this variable is used to rebind help-form locally inside the minibuffer (see Help Functions).

Variable: minibuffer-scroll-window

If the value of this variable is non-nil, it should be a window object. When the function scroll-other-window is called in the minibuffer, it scrolls this window (see Textual Scrolling).

Function: minibuffer-selected-window

This function returns the window that was selected just before the minibuffer window was selected. If the selected window is not a minibuffer window, it returns nil.

Function: minibuffer-message string &rest args

This function displays string temporarily at the end of the minibuffer text, for a few seconds, or until the next input event arrives, whichever comes first. The variable minibuffer-message-timeout specifies the number of seconds to wait in the absence of input. It defaults to 2. If args is non-nil, the actual message is obtained by passing string and args through format-message. See Formatting Strings.

Command: minibuffer-inactive-mode

This is the major mode used in inactive minibuffers. It uses keymap minibuffer-inactive-mode-map. This can be useful if the minibuffer is in a separate frame. See Minibuffers and Frames.
