children() click to toggle source

Returns the arguments to the function.

@return [Array] @see Node#children

    # File lib/sass/script/funcall.rb, line 51

52:         @args
53:       end

context=(context) click to toggle source

Don’t set the context for child nodes if this is `url()`, since `url()` allows quoted strings.

@param context [Symbol] @see Node#context=

    # File lib/sass/script/funcall.rb, line 25
25:       def context=(context)
26:         super unless @name == "url"
27:       end

inspect() click to toggle source

@return [String] A string representation of the function call

    # File lib/sass/script/funcall.rb, line 38
38:       def inspect
39:         "#{name}(#{args.map {|a| a.inspect}.join(', ')})"
40:       end

Protected Instance Methods

_perform(environment) click to toggle source

Evaluates the function call.
