evil-text-object-go.el

Overview

This Emacs package (evil-text-object-go) extends Evil (evil-mode) with text objects that operate on Go functions.

evil-text-object-inner-go-function is the 'inner' text object that selects the actual code of the current function(s)

evil-text-object-outer-go-function is the 'outer' text object that selects the current function(s) and surrounding whitespace.

The default key bindings are if and af, which can be memorised as 'inner function' and 'a function'.

Installation

Emacs

Install from Melpa:

M-x package-install RET evil-text-object-go RET

Then add this to init.el:

(add-hook 'go-mode-hook 'evil-text-object-go-add-bindings)

Spacemacs

Add evil-text-object-go to your .spacemacs file in the additional packages list:

dotspacemacs-additional-packages'((evil-text-object-go))

Then add (add-hook 'go-mode-hook 'evil-text-object-go-add-bindings) to your user-config function in .spacemacs file:

(defun dotspacemacs/user-config ()
  "Configuration for user code:
This function is called at the very end of Spacemacs startup, after layer
configuration.
Put your configuration code here, except for variables that should be set
before packages are loaded."
  (use-package evil-text-object-go)
  (add-hook 'go-mode-hook 'evil-text-object-go-add-bindings))

Note that the implementation uses various Go navigation commands provided by go-mode.

Customisation

The default key binding uses the letter f (if and af), but can be customised by changing evil-text-object-go-statement-key. For example:

(setq evil-text-object-go-statement-key "x")

Alternatively, use the Customize interface:
