In: |

|
Parent: | RootNode |
A static node that wraps the {Sass::Tree} for an `@import`ed file. It doesn‘t have a functional purpose other than to add the `@import`ed file to the backtrace if an error occurs.
imported_filename | [R] |
The name of the imported file as it appears in the Sass document.
@return [String] |
@param imported_filename [String] The name of the imported file
# File lib/sass/tree/import_node.rb, line 13 13: def initialize(imported_filename) 14: @imported_filename = imported_filename 15: super(nil) 16: end
@see Node#cssize
# File lib/sass/tree/import_node.rb, line 42 42: def cssize(*args) 43: super.first 44: end
Returns the resolved name of the imported file, as returned by \{Sass::Files#find_file_to_import}.
@return [String] The filename of the imported file.
This is an absolute path if the file is a `".sass"` or `".scss"` file.
@raise [Sass::SyntaxError] if `filename` ends in `".sass"` or `".scss"`
and no corresponding Sass file could be found.

Returns a static DirectiveNode if this is importing a CSS file, or parses and includes the imported Sass file.
@param environment [Sass::Environment] The lexical environment containing
variable and mixin values

Parses the imported file and runs the dynamic Sass for it.
