Can Occur center the found text in the buffer?

Question

When selecting an item from the occur buffer, the highlighted line is at the very bottom of the visible screen. This is less useful than having it 25-50% of the way down the screen(so it's easy to read the text around the found line). Is this possible?

I don't see the behavior that you describe, at all. For me, when I choose an occurrence in buffer *Occur* it visits the occurrence in the source buffer, putting that smack in the middle of the source-buffer window (vertically).

But if you see what you describe, then just put some window-recentering code on occur-mode-find-occurrence-hook.

Something like this. You can use any comparison condition you like. Here, I used "within 10 lines of the top or bottom", but you could use percentages etc.

(defun foo ()
  (let ((line   (line-number-at-pos)))
    (cond ((<= line (+ (line-number-at-pos (window-start)) 10))
           (recenter 10))
          ((>= line (- (line-number-at-pos (window-end)) 10))
           (recenter -10)))))

(add-hook 'occur-mode-find-occurrence-hook 'foo)
