Setup jshint in emacs

gistfile1.txt

This seems to run quicker than the jshint-mode example (https://github.com/daleharvey/jshint-mode) as it doesn't set up a node server each time.


1. Install node and get jshint

$ brew install node
$ npm install -g jshint


2. Update PATH to point to Node Packagem Manager bin directory

$ export PATH=$PATH:/usr/local/share/npm/bin


3. Get flymake-cursor (shows warnings/errors in buffer for using terminal)

$ curl http://www.emacswiki.org/emacs/download/flymake-cursor.el > ~/.elisp/flymake-mode.el


4. Update .emacs file

;; jshint
(when (load "flymake" t)
  (defun flymake-jshint-init ()
    (let* ((temp-file (flymake-init-create-temp-buffer-copy
                              'flymake-create-temp-inplace))
           (local-file (file-relative-name
                        temp-file
                        (file-name-directory buffer-file-name))))
      (list "jshint"
            (list local-file))
      ))
  (setq flymake-err-line-patterns
        (cons '("^.*: line \\([[:digit:]]+\\), col \\([[:digit:]]+\\), \\(.*\\)$"
                nil 1 2 3)
              flymake-err-line-patterns))
  (add-to-list 'flymake-allowed-file-name-masks
               '("\\.js\\'" flymake-jshint-init))
  (require 'flymake-cursor))

;; Auto load witn javascript file 
(add-hook 'js-mode-hook
     (lambda ()
       (flymake-mode t)
       (define-key js-mode-map "\C-c\C-n" 'flymake-goto-next-error)))
