|
;; Works with either "jslint" from jslint.com, or "jsl" from
|
|
;; javascriptlint.com. The default is "jsl", if that executable is
|
|
;; found at load-time. Otherwise, "jslint" is the default. If you want
|
|
;; to use the non-default checker, you can customize the values of
|
|
;; `flymake-jslint-command' and `flymake-jslint-args' accordingly.
|
|
;;
|
|
;; Usage:
|
|
;; (require 'flymake-jslint)
|
|
;; (add-hook 'js-mode-hook 'flymake-jslint-load)
|
|
;;
|
|
;; Uses flymake-easy, from https://github.com/purcell/flymake-easy
