Problem with aliases

[dvzubarev]

Hi, I have emacs 24.5.1, with installed evil and evil-snipe. I sequentially evaled following expressions in scratch buffer.

(evil-mode)
(setq evil-snipe-scope 'buffer)
(evil-snipe-override-mode 1)
(evil-snipe-mode 1)
(evil-snipe-add-alias ?\[ "[[{(]")

Then I press f[ and '(' are highlighted, it is OK. After creating new file with some text "(test { test)", the defined alias is not working, i.e. { or ( are not highlighted and I can not jump to them by hitting f[. The output of M-x describe-key is evil-snipe-f though.

Ah, I made a huge oversight with evil-snipe-add-alias. You see, evil-snipe-symbol-groups is buffer local, so any aliases you define with evil-snipe-add-alias will only apply to your current buffer. Whoops!

You can define global aliases with:

(setq-default evil-snipe-symbol-groups '((?\[ "[[{(]")))

I will push an update later tonight that will change evil-snipe-add-alias to (evil-snipe-add-alias MODE CHAR REGEX), for mode-specific aliases (and global aliases if MODE is nil).

In either case, setting evil-snipe-symbol-groups directly will work in any version of evil-snipe.

Alright, I ended up getting rid of evil-snipe-add-alias for simplicity's sake.

To parrot the README (that will be updated in a few moments):

• To map [ to any opening parentheses or bracket in all modes:

  (push '(?[ "[[{(]") evil-snipe-aliases)

  Therefore, sa[ will match a[, a{ or a(

• To map : to a python function (but only in python-mode):

  (add-hook 'python-mode-hook
  (lambda ()
    (make-variable-buffer-local 'evil-snipe-aliases)
    (push '(?: "def .+:") evil-snipe-aliases)))

Note: evil-snipe-alias is aliased to evil-snipe-symbol-groups, so this shouldn't break backwards compatibility. Well, unless you use evil-snipe-add-alias.

i.e. This will still work fine:

(setq-default evil-snipe-symbol-groups '((?\[ "[[{(]")))
