npm control characters in compilation output

[Shakthi Kannan <shakthimaan@gmail.com>]

Hi,

I am currently testing the following code snippet:

=== ~/.emacs ===

(setq inferior-js-mode-hook
      (lambda ()
        ;; We like nice colors
        (ansi-color-for-comint-mode-on)
        ;; Deal with some prompt nonsense
        (add-to-list
         'comint-preoutput-filter-functions
         (lambda (output)
           (replace-regexp-in-string "\033\\[[0-9]+[GK]" "" output)))))

;; for displaying ANSI escape sequences correctly
(eval-after-load 'compile
  '(add-hook 'compilation-filter-hook
        (lambda () (ansi-color-process-output nil))))

(defun npm-test ()
  (interactive)
  (let ((root (locate-dominating-file default-directory "package.json")))
    (unless root
      (error "Here is not npm package"))
    (let ((default-directory root))
      (compile "npm run test"))))

=== END ===

After evaluating the above functions, and running 'npm-test', I still
see control characters in the *Compilation* buffer. What could I be
missing?

The detailed issue is available at:

Appreciate any help in this regard,

Thanks!

SK
