;;; Commentary:
|
|
|
|
;; This package requires the "jsonlint" program, which can be installed using npm:
|
|
;;
|
|
;; npm install jsonlint -g
|
|
;;
|
|
;; Usage:
|
|
;;
|
|
;; (require 'flymake-json)
|
|
;;
|
|
;; Then, if you're using `json-mode':
|
|
;;
|
|
;; (add-hook 'json-mode-hook 'flymake-json-load)
|
|
;;
|
|
;; or, if you use `js-mode' for json:
|
|
;;
|
|
;; (add-hook 'js-mode-hook 'flymake-json-maybe-load)
|
|
;;
|
|
;; otherwise:
|
|
;;
|
|
;; (add-hook 'find-file-hook 'flymake-json-maybe-load)
|
|
;;
|
|
;; Uses flymake-easy, from https://github.com/purcell/flymake-easy
