The Compass configuration data storage class manages configuration data that comes from a variety of different sources and aggregates them together into a consistent API Some of the possible sources of configuration data:
* Compass default project structure for stand alone projects * App framework specific project structures for rails, etc. * User supplied explicit configuration * Configuration data provided via the command line interface
There are two kinds of configuration data that doesn't come from the user:
Configuration data that is defaulted as if the user had provided it themselves. This is useful for providing defaults that the user is likely to want to edit but shouldn't have to provide explicitly when getting started
Configuration data that is defaulted behind the scenes because some value is required.
# File lib/compass/configuration/data.rb, line 81 def add_import_path(*paths) paths.map!{|p| defined?(Pathname) && Pathname === p ? p.to_s : p} # The @added_import_paths variable works around an issue where # the additional_import_paths gets overwritten during parse @added_import_paths ||= [] @added_import_paths += paths self.additional_import_paths ||= [] self.additional_import_paths += paths end
When called with a block, defines the cache buster strategy to be used. If the block returns nil or a string, then it is appended to the url as a query parameter. In this case, the returned string must not include the starting '?'. The block may also return a hash with :path and/or :query values and it will replace the original path and query string with the busted values returned. The block will be passed the root-relative url of the asset. If the block accepts two arguments, it will also be passed a File object that points to the asset on disk -- which may or may not exist. When called without a block, returns the block that was previously set.
To disable the asset cache buster:
asset_cache_buster :none
# File lib/compass/configuration/data.rb, line 122 def asset_cache_buster(simple = nil, &block) @set_attributes ||= {} if block_given? @set_attributes[:asset_cache_buster] = true @asset_cache_buster = block elsif !simple.nil? if simple == :none @set_attributes[:asset_cache_buster] = true @asset_cache_buster = Proc.new {|_,_| nil} else raise ArgumentError, "Unexpected argument: #{simple.inspect}" end else if set?(:asset_cache_buster) @asset_cache_buster elsif inherited_data.respond_to?(:asset_cache_buster) inherited_data.asset_cache_buster end end end
When called with a block, defines the asset host url to be used. The block must return a string that starts with a protocol (E.g. http). The block will be passed the root-relative url of the asset. When called without a block, returns the block that was previously set.
# File lib/compass/configuration/data.rb, line 95 def asset_host(&block) @set_attributes ||= {} if block_given? @set_attributes[:asset_host] = true @asset_host = block else if @asset_host @asset_host elsif inherited_data.respond_to?(:asset_host) inherited_data.asset_host end end end
Finds all extensions within a directory and registers them.
# File lib/compass/configuration/data.rb, line 170 def discover(frameworks_dir) (self.framework_path ||= []) << frameworks_dir Compass::Frameworks.discover frameworks_dir end
# File lib/compass/configuration/data.rb, line 164 def load(framework_dir) (self.loaded_frameworks ||= []) << framework_dir Compass::Frameworks.register_directory framework_dir end
# File lib/compass/configuration/data.rb, line 175 def relative_assets? # the http_images_path is deprecated, but here for backwards compatibility. relative_assets || http_images_path == :relative end
Require a compass plugin and capture that it occured so that the configuration serialization works next time.
# File lib/compass/configuration/data.rb, line 159 def require(lib) (self.required_libraries ||= []) << lib super end
# File lib/compass/configuration/data.rb, line 72 def set_all(attr_hash) # assert_valid_keys!(attr_hash) attr_hash.each do |a, v| if self.respond_to?("#{a}=") self.send("#{a}=", v) end end end
