SassScript is code that‘s embedded in Sass documents to allow for property values to be computed from variables.
This module contains code that handles the parsing and evaluation of SassScript.
MATCH | = | /^[!\$](#{Sass::SCSS::RX::IDENT})\s*((?:\|\|)?=|:)\s*(.+?)(!(?i:default))?$/ | The regular expression used to parse variables. | |
VALIDATE | = | /^[!\$]#{Sass::SCSS::RX::IDENT}$/ | The regular expression used to validate variables without matching. |

Parses a string of SassScript
@param value [String] The SassScript @param line [Fixnum] The number of the line on which the SassScript appeared.
Used for error reporting
@param offset [Fixnum] The number of characters in on `line` that the SassScript started.
Used for error reporting
@param options [{Symbol => Object}] An options hash;
see {file:SASS_REFERENCE.md#sass_options the Sass options documentation}
@return [Script::Node] The root node of the parse tree
