Request: scroll to top of alchemist-refcard by default #279

Open jmitchell opened 7 years ago

jmitchell commented 7 years ago

When I open the refcard now using C-c a h r the point is at the bottom, and it's not immediately obvious there's more content toward the top. It would be nice if the refcard opened scrolled to the top by default, at least when the buffer is first created.

This elisp expression does it when *alchemist-refcard* is already open.

(set-window-point (get-buffer-window alchemist-refcard--buffer-name) (point-min))

In case anyone else wants the same thing now, this works:

(define-key alchemist-mode-keymap (kbd "?")
  (lambda ()
    (interactive)
    (ignore-errors (alchemist-refcard))
    (set-window-point (get-buffer-window alchemist-refcard--buffer-name)
                      (point-min))))

The ignore-errors bit is necessary to overcome #278.
