javascript - Coffeescript generating blank JS file in Rails 3.2 -

edit: full reboot of machine running rails server has fixed this.

i'm getting strange problem in 1 of coffeescript files compiling empty javascript file. file had been compiling fine , randomly stopped working. can enter in file, code should throw error , still generates empty js file.

i have run rake assets:clean , have never run rake assets:precompile in development environment. i've checked public/assets directory , there nothing in it. have tried clearing browser cache , didn't work either.

here in events.js.coffee file

console.log 'test' 

and here being output events.js

(function() {   }).call(this); 

here application.js.coffee file

#= require jquery #= require jquery_ujs #= require sugar #= require foundation #= require fullcalendar #= require jquery.ui.all #= require_self #= require_tree .  $(document).foundation 

if has ideas appreciated.

i faced issue , caching in browser. emptied , started working. (that's why full restart worked , not restarting rails server)
