relative-jump.el

Relative, alphanumeric line jumping.

A simple package to allow the user to jump relative lines using an alphanumeric relative line numbering.

Why?

I never really got into ace-jump, a fault of my own. I found that I tended to think more in terms of lines than target characters. When using ace-jump I found myself pausing to wait for the target character to be labeled before moving on.

relative-jump is a little different because the lines are always there and you can type the line offset while examining the target region or thinking about what you're going to do when you get there.

Usage

Put relative-jump.el in your load-path. My config looks something like this:

(require 'relative-jump)

;; Bind Control-Alt-n to a forward jump
(global-set-key (kbd "C-M-n") 'relative-jump-forward)

;; Bind Control-Alt-p to a backward jump
(global-set-key (kbd "C-M-p") 'relative-jump-backward)

;; Set the linum format
(setq linum-relative-format "%3s› ")

Example

With the above setup, the keystrokes C-M-n c RET will jump forward to line c containing ((symbolp x) (symbol-value x))).

d ›
c ›
b › (cond ((numberp x) x)
a ›       ((stringp x) x)
  ›       ((bufferp x)
a ›        (setq temporary-hack x) ; multiple body-forms
b ›        (buffer-name x))        ; in one clause
c ›       ((symbolp x) (symbol-value x)))
d ›

For longer buffers, the letters are appended with a number multiplier.

d › (cond ((numberp x) x)
c ›       ((stringp x) x)
b ›       ((bufferp x)
a ›        (setq temporary-hack x) ; multiple body-forms
  ›        (buffer-name x))        ; in one clause
a ›       ((symbolp x) (symbol-value x)))
...
a2›
b2›
c2›
..
a3›
b3›

You simply enter a3, c2, b3, etc. to jump to line specified!
