Emacs Go Lang结构对齐文本

Question

In go we have structs like this:

type person struct {  
   firstname string  
   lastname string  
   age int  
   address string  

}  

I want it to be aligned like this

type person struct {
   firstname string
   lastname  string
   age       int
   address   string

}  

and stuff like

const (  
    constant1 int = 1  
    c2 int = 2  
    const3 int = 3  
)    

to

const (    
    constant1   int = 1  
    c2          int = 2  
    const3      int = 3  
)  

I know align-regexp should help here, but i am unable to figure it out.

Answer 1

Have you tried go-mode ? It will use fmt or goimport to format you code.

Answer 2

是的，我正在使用go-mode和go-fmt都未对齐

Answer 3

go-mode should run gofmt or goimports if you put it in the save hook.

(use-package go-mode
  :config
  (when (executable-find "goimports")
    (setq gofmt-command "goimports"))
  (defun jpk/go-mode-hook ()
    (add-hook 'before-save-hook #'gofmt-before-save nil 'local))
  (add-hook 'go-mode-hook #'jpk/go-mode-hook)
  )
