Allow jumping to the first and last occurrence of a symbol about symbol-overlay HOT 6 CLOSED

Yep, that would be useful.

from symbol-overlay.

Before having this new feature, you might found it helpful using symbol-overlay-switch-backward/forward:

1. highlight the target symbol first
2. go to the beginning/end of the buffer
3. trigger the command to jump to the target symbol

from symbol-overlay.

@wolray I tried the steps you're suggesting, but it's not as quick as having the possibility to jump straight to the first/last occurrence.

After dig into the source code for 10 mins, I have made one, hope it helps:

BTW. Emacs really rocks. 😄

(defun symbol-overlay-switch-first ()
  (interactive)
  (let* ((symbol (symbol-overlay-get-symbol))
         (keyword (symbol-overlay-assoc symbol))
         (a-symbol (car keyword))
         (before (symbol-overlay-get-list a-symbol 'car))
         (count (length before)))
    (symbol-overlay-jump-call 'symbol-overlay-basic-jump (- count))))

(defun symbol-overlay-switch-last ()
  (interactive)
  (let* ((symbol (symbol-overlay-get-symbol))
         (keyword (symbol-overlay-assoc symbol))
         (a-symbol (car keyword))
         (after (symbol-overlay-get-list a-symbol 'cdr))
         (count (length after)))
    (symbol-overlay-jump-call 'symbol-overlay-basic-jump (- count 1))))

(define-key symbol-overlay-map (kbd "<") 'symbol-overlay-switch-first)
(define-key symbol-overlay-map (kbd ">") 'symbol-overlay-switch-last)

A few people have asked for this now, so I feel this is worth adding. Would someone like to file a pull request, perhaps based on the snippet above?

Commands are added as symbol-overlay-jump-first and symbol-overlay-jump-last.
