nil

Documentation

Non-nil if Temp-Buffer-Resize mode is enabled.

See the temp-buffer-resize-mode(var)/temp-buffer-resize-mode(fun) command for a description of this minor mode. Setting this variable directly does not take effect; either customize it (see the info node (emacs)Easy Customization) or call the function temp-buffer-resize-mode(var)/temp-buffer-resize-mode(fun).

Probably introduced at or before Emacs version 20.4.

(define-minor-mode temp-buffer-resize-mode
  "Toggle auto-resizing temporary buffer windows (Temp Buffer Resize Mode).

When Temp Buffer Resize mode is enabled, the windows in which we
show a temporary buffer are automatically resized in height to
fit the buffer's contents, but never more than
`temp-buffer-max-height' nor less than `window-min-height'.

A window is resized only if it has been specially created for the
buffer.  Windows that have shown another buffer before are not
resized.  A frame is resized only if `fit-frame-to-buffer' is
non-nil.

This mode is used by `help', `apropos' and `completion' buffers,
and some others."
