standardfmt.el

Emacs minor-mode to format JavaScript with standard / semistandard on save.

Core parts of standardfmt.el are borrowed from go-mode and it's invocation of gofmt.

Installing

Drop standardfmt.el somewhere into you load-path. I favour the folder ~/.emacs.d/vendor:

(add-to-list 'load-path "~/.emacs.d/vendor")
(require 'standardfmt)

Usage

To enable formatting JavaScript buffers on save, simply enable standardfmt-mode. If you use js-mode to edit JavaScript buffers, something like this will do the trick:

(add-hook 'js-mode-hook #'standardfmt-mode)

Commands

• standardfmt - Format current buffer with standard/semistandard.
• standardfmt-mode - Toggle formatting on save.

Customization

Use Semistandard

By default standard will be used, but you can change it to use semistandard by customizing standardfmt-command with M-x customize-variable or:

(setq standardfmt-command "semistandard")
