I can't set Emacs to work with Javascript. I want Emacs makes auto indent, when I press "{" and "}". When I write code on C, it works very well. When I press "}" the parenthesis tooks its place. I'd like to see something like this:
But I get this:
I don't understand why parenthesis remain in place.
Could you tell me, what should I do to make it right, please?
I think, I need to add something to my .emacs file, aren't I?
Here is my .emacs:
(setq c-default-style "bsd"
c-basic-offset 4)
(setq-default c-basic-offset 4
tab-width 4
indent-tabs-mode nil)
(setq make-backup-files nil
auto-save-default nil
auto-save-list-file-name nil)
(global-set-key (kbd "RET") 'newline-and-indent)
(show-paren-mode t) ; Highlight expression between {}, (), []
(setq show-paren-style 'parenthesis) ; parenthesis | expression | mixed
(add-hook 'html-mode-hook
(lambda ()
;; Default indentation is usually 2 spaces, changing to 4.
(set (make-local-variable 'sgml-basic-offset) 2)
(setq tab-width 2)
)
)
(setq font-lock-maximum-decoration
'((html-mode . 1)))
(setq column-number-mode t)
;(electric-pair-mode t)
;(setq electric-pair-preserve-balance nil)
;(electric-indent-mode -1)
; 80 letters rule (highlight)
(setq-default
whitespace-line-column 78
whitespace-style '(face lines-tail))
(add-hook 'prog-mode-hook #'whitespace-mode) ; only if I write code
(add-hook 'text-mode-hook #'whitespace-mode) ; and the other cases
; Use all c-mode settings when I code on javascript (indent, tab-width, ...)
;(add-hook 'js-mode-hook 'c-mode)
;(add-hook 'js-mode-hook #'c-default-style)
;(add-to-list 'auto-mode-alist '("\\.js\\'" . c-mode))
I couldn't find any built-in functions or ready-made solution, so I read emacs documentation and wrote my own emacs-lisp function. Maybe someone will need it.
(global-set-key (kbd "RET") 'newline-and-indent)
(add-hook 'js-mode-hook
(lambda()
(local-set-key (kbd "{")
(lambda() (interactive)
(my-bsd-lparen-align)
(insert "{")
)
)
(local-set-key (kbd "}")
(lambda() (interactive)
(insert "}")
(indent-according-to-mode)
;(c-indent-command)
)
)
)
)
(defun my-bsd-lparen-align()
(skip-chars-forward " \t")
(setq cur_pos (point))
(my-line-begin)
(setq new_pos (point))
(goto-char cur_pos)
(if (eq cur_pos new_pos)
(__my-bsd-lparen-put)
)
)
(defun my-line-begin()
(beginning-of-line)
(skip-chars-forward " \t")
(current-column)
)
(defun __my-bsd-lparen-put()
(setq init_pos (point))
(setq cur_start (my-line-begin))
(forward-line -1)
(setq block_start (my-line-begin))
(setq diff (- cur_start block_start))
(goto-char init_pos)
(if (>= diff 0)
(delete-backward-char diff)
(loop for i from 1 to (- diff) do (insert " "))
)
)
