#initialize(root = ".") {|_self| ... } ⇒ Environment
‘Environment` should initialized with your application’s root directory. This should be the same as your Rails or Rack root.
env = Environment.new(Rails.root)

# File 'lib/sprockets/environment.rb', line 72 def find_asset(path, = {}) [:bundle] = true unless .key?(:bundle) # Ensure inmemory cached assets are still fresh on every lookup if (asset = @assets[cache_key_for(path, )]) && asset.fresh?(self) asset elsif asset = index.find_asset(path, ) # Cache is pushed upstream by Index#find_asset asset end end |
#index ⇒ Object
Returns a cached version of the environment.
All its file system calls are cached which makes ‘index` much faster. This behavior is ideal in production since the file system only changes between deploys.
