eno.el

ace-jump/easymotion provides “goto certain char in view”, which let us moving without mouse, but it’s still not efficient or intuitive enough, so I create this package to not just goto but also edit(copy,cut..) any word/symbol/string/paren/line in view by directly selecting hints, similar to ace-jump/easymotion but don’t need to enter the leading char.

install

M-x package-install eno

word

symbol

string

line

paren - (), [], {}

default config / customization

(eno-set-all-letter-str "e trinaodsuh(k[lgm,bpcyfvwjqz")

letters used for generating hints

for qwerty: (eno-set-all-letter-str " sdfjkla;weioqpruvncmghxz,./")

(eno-set-same-finger-list '("(aq" "dtb" "sr," "lmjv" "gwpc" "uiy" "hnf" "koz["))

list of same finger letters, e.g. if you set it as ’(“qa” “ws”), then the hint “qa”, “aq”, “ws” and “sw” won’t show.

for qwerty: (eno-set-same-finger-list '("qaz" "wsx" "edc" "rfvg" "ujmhn" "ik," "ol." "p;/"))

(NOTE: eno’s hints generation algorithm is optimized for one and two letter, and doesn’t support three or above letters)

(setq eno-stay-key-list '("<prior>" "<next>" "<wheel-up>" "<wheel-down>"))

by default if you entered a key that’s not in the all-letter-str, eno will quit and trigger the key, except the key in this list.

eno-hint-face

face used for hints.

(defun eno (re &optional at-head aside) ...)

you can write your own command based on eno by calling it with a regexp to match strings in view, optionally passing the arguments to specify whether the hint should appear at head and whether appear aside the matching strings.
