Sass::Script::Node

The options hash for this node.

@return [{Symbol => Object}]

The context in which this node was parsed, which determines how some operations are performed.

Can be `:equals`, which means it’s part of a `$var = val` or `prop = val` assignment, or `:default`, which means it’s anywhere else (including `$var: val` and `prop: val` assignments, `#{}`-interpolations, and other script contexts such as `@if` conditions).

@return [Symbol]

The line of the document on which this node appeared.

@return [Fixnum]

Creates a new script node.

    # File lib/sass/script/node.rb, line 49
49:     def initialize
50:       @context = :default
51:     end

Returns all child nodes of this node.

@return [Array]

    # File lib/sass/script/node.rb, line 70
70:     def children
71:       raise NotImplementedError.new("All subclasses of Sass::Script::Node must override #children.")
72:     end

Sets the context for this node, as well as for all child nodes.

@param context [Symbol] @see #

    # File lib/sass/script/node.rb, line 43
43:     def context=(context)
44:       @context = context
45:       children.each {|c| c.context = context}
46:     end

Sets the options hash for this node, as well as for all child nodes. See {file:SASS_REFERENCE.md#sass_options the Sass options documentation}.

@param options [{Symbol => Object}] The options

    # File lib/sass/script/node.rb, line 33
33:     def options=(options)
34:       @options = options
35:       children.each {|c| c.options = options}
36:     end

Evaluates the node.

{#perform} shouldn’t be overridden directly; instead, override {#_perform}.

@param environment [Sass::Environment] The environment in which to evaluate the SassScript @return [Literal] The SassScript object that is the value of the SassScript

    # File lib/sass/script/node.rb, line 60
60:     def perform(environment)
61:       _perform(environment)
62:     rescue Sass::SyntaxError => e
63:       e.modify_backtrace(:line => line)
64:       raise e
65:     end

Returns the text of this SassScript expression.

@return [String]

78:       raise NotImplementedError.new("All subclasses of Sass::Script::Node must override #to_sass.")
79:     end

Evaluates this node.

@param environment [Sass::Environment] The environment in which to evaluate the SassScript @return [Literal] The SassScript object that is the value of the SassScript @see #

Converts underscores to dashes if the :dasherize option is set.

    # File lib/sass/script/node.rb, line 84
84:     def dasherize(s, opts)
