Highlight Tail for Emacs

highlight-tail-for-emacs.gifThis is a cool little minor mode hack for Emacs. It’s like a last-typed heat map.

Onlookers will be amazed as you burn up the screen with your brilliant code.

Update: Rafal Jedruszek’s site above has gone AWOL, so I am preserving a copy here:

Highlight Tail version 1.3.9 (02 Apr 2007).

    This Script can be easily updated to update on fade out on keypresses on time rather than time by adding a removing a few lines. The changes are shown below.

    ~ Line 539:
    (defun highlight-tail-make-new-overlay ()
    “Make new highlight in the current point.”
    (let* ((end-point (point))
    (start-point (1- end-point))
    (point-face-bgcolor-hex nil))
    ;; remove any highlight-tail’s overlays at point
    (let ((overlays-at-start-point (highlight-tail-overlays-at start-point))

    (setq highlight-tail-fading-timer
    (if (featurep ‘xemacs) ()()))
    ;(start-itimer “highlight-tail-fade-out-step”
    ; ‘highlight-tail-fade-out-step
