Public Class Methods
engine_initialized?()

Templates are initialized once the functions are added.
Calls superclass method
# File lib/sprockets/sass/sass_template.rb, line 19 def engine_initialized? super && sass_functions_initialized? end
Public Instance Methods
evaluate(context, locals, &block)

See `Tilt::Template#evaluate`.
# File lib/sprockets/sass/sass_template.rb, line 50 def evaluate(context, locals, &block) @output ||= begin @context = context ::Sass::Engine.new(data, sass_options).render rescue ::Sass::SyntaxError => e # Annotates exception message with parse line number context.__LINE__ = e.sass_backtrace.first[:line] raise e end end
initialize_engine()
click to toggle source
Add the Sass functions if they haven't already been added.
Calls superclass method
# File lib/sprockets/sass/sass_template.rb, line 25 def initialize_engine super unless self.class.superclass.engine_initialized? if Sass.add_sass_functions != false begin require 'sprockets/helpers' require 'sprockets/sass/functions' rescue LoadError; end end self.class.sass_functions_initialized = true end
prepare()

See `Tilt::Template#prepare`.
# File lib/sprockets/sass/sass_template.rb, line 44 def prepare @context = nil @output = nil end
syntax()

Define the expected syntax for the template
# File lib/sprockets/sass/sass_template.rb, line 39 def syntax :sass end
Protected Instance Methods
cache_store()
click to toggle source
Returns a Sprockets-aware cache store for Sass::Engine.
# File lib/sprockets/sass/sass_template.rb, line 64 def cache_store return nil if context.environment.cache.nil? if defined?(Sprockets::SassCacheStore) Sprockets::SassCacheStore.new context.environment else CacheStore.new context.environment end end
default_sass_options()
click to toggle source
Get the default, global Sass options. Start with Compass's options, if it's available.
# File lib/sprockets/sass/sass_template.rb, line 97 def default_sass_options if defined?(Compass) merge_sass_options Compass.sass_engine_options.dup, Sprockets::Sass.options else Sprockets::Sass.options.dup end end
merge_sass_options(options, other_options)
click to toggle source
Merges two sets of `Sass::Engine` options, prepending the `:load_paths` instead of clobbering them.
# File lib/sprockets/sass/sass_template.rb, line 107 def merge_sass_options(options, other_options) if (load_paths = options[:load_paths]) && (other_paths = other_options[:load_paths]) other_options[:load_paths] = other_paths + load_paths end options.merge other_options end
sass_options()
click to toggle source
Assemble the options for the `Sass::Engine`
# File lib/sprockets/sass/sass_template.rb, line 75 def sass_options # Allow the use of custom SASS importers, making sure the # custom importer is a `Sprockets::Sass::Importer` if default_sass_options.has_key?(:importer) && default_sass_options[:importer].is_a?(Importer) importer = default_sass_options[:importer] else importer = Importer.new end merge_sass_options(default_sass_options, options).merge( :filename => eval_file, :line => line, :syntax => syntax, :cache_store => cache_store, :importer => importer, :custom => { :sprockets_context => context } ) end
