My algorithm growing the minibuffer window emulates Gerd's. But there
is no algorithm for shrinking the minibuffer window because no reliable
one exists. Gerd stores all original window heights before growing the
minibuffer window and emulates shrinking to the original line by writing
them back into the height fields of the window structure. This requires
some care and can fail, for example, when resizing the frame with an
enlarged minibuffer. And IIUC this is also the reason for the somewhat
strange default value `grow-only' for `resize-mini-windows'.
Look at Gerd's shrinking routine below:
shrink_mini_window (w)
struct window *w;
{
struct frame *f = XFRAME (w->frame);
struct window *root = XWINDOW (FRAME_ROOT_WINDOW (f));
if (save_restore_orig_size (root, CHECK_ORIG_SIZES))
----> This is taken if heights were stored earlier and the size check
suceeds. Note that it just restores the original sizes, there's
no shrinking from say 3 to 2 lines.
{
save_restore_orig_size (root, RESTORE_ORIG_SIZES);
adjust_glyphs (f);
FRAME_WINDOW_SIZES_CHANGED (f) = 1;
windows_or_buffers_changed = 1;
}
else if (XFASTINT (w->total_lines) > 1)
----> This is the branch taken in the `resize-mini-windows' t case or
when the size check above fails. It does the old enlarge_window
routine which can shed bad results and in some cases even delete
the windows it's supposed to enlarge. This could also shrink a
minibuffer from 3 to 2 lines; but that feature is not used, likely
because Gerd trusted that nobody would want it. So, by force, the
minibuffer window always shrinks back to one line.
{
/* Distribute the additional lines of the mini-window
among the other windows. */
Lisp_Object window;
XSETWINDOW (window, w);
enlarge_window (window, 1 - XFASTINT (w->total_lines), 0);
}
}
