evil-extra-operator

Evil operator for evaluating codes, translating text, taking notes, searching via google, etc.

Installation

;; change default key bindings (if you want) HERE
;; (setq evil-extra-operator-eval-key (kbd "ge"))
(require 'evil-extra-operator)
(global-evil-extra-operator-mode 1)

The key binding customization must be placed BEFORE (require 'evil-extra-operator).

Or you can just choose what commands you need and bind them yourself:

(require 'evil-extra-operator)
(define-key evil-motion-state-map "gr" 'evil-operator-eval)
(define-key evil-motion-state-map "g'" 'evil-operator-google-translate)

Commands and default bindings

gr (evil-operator-eval)

Operator for evaluating code, i.e., use grip to evaluate current paragraph, grr to evaluate current line, or if you are in visual state, gr to evaluate current active region. You can customize option evil-extra-operator-eval-modes-alist to let evil-operator-eval support more language. Example:

(setq evil-extra-operator-eval-modes-alist
  '((ruby-mode ruby-send-region)
    (enh-ruby-mode ruby-send-region)))

See document of this option for details.


gG (evil-operator-google-search)

Operator to search the web via google.


g. (evil-operator-google-translate)

Operator to translate text via google translate. To use this command, you should have google-translate installed.


gh (evil-operator-highlight)

Operator to highlight region. To use this command, you should have highlight.el installed. You can use hlt-eraser-mouse or hlt-eraser which are provided by highlight.el to erase highlighted area.


gs (evil-operator-fold)

Operator to fold region. To use this command, you should have fold-this.el installed. You can use fold-this-unfold-at-point or fold-this-unfold-all which are provided by fold-this.el for unfolding.


go (evil-operator-org-capture)

Operator form of org-capture. So you can use goip to capture current paragraph.


gR (evil-operator-remember)

No default binding (evil-operator-query-replace)

Operator to query and replace a region throughout the current buffer.
