Parent: | Object |
The parser for SassScript. It parses a string of code into a tree of {Script::Node}s.
@param str [String, StringScanner] The source text to parse @param line [Fixnum] The line on which the SassScript appears.
Used for error reporting
@param offset [Fixnum] The number of characters in on which the SassScript appears.
Used for error reporting
@param filename [String] The name of the file in which the SassScript appears.
Used for error reporting

Parses a SassScript expression.

# File lib/sass/script/parser.rb, line 81 81: def self.parse(*args) 82: new(*args).parse 83: end
Parses a SassScript expression.
@return [Script::Node] The root node of the parse tree @raise [Sass::SyntaxError] if the expression isn‘t valid SassScript
# File lib/sass/script/parser.rb, line 37 37: def parse 38: expr = assert_expr :expr 39: assert_done 40: expr 41: end
Parses a SassScript expression within an interpolated segment (`#{}`). This means that it stops when it comes across an unmatched `}`, which signals the end of an interpolated segment, it returns rather than throwing an error.
@return [Script::Node] The root node of the parse tree @raise [Sass::SyntaxError] if the expression isn‘t valid SassScript

Parses the argument list for a mixin definition.
@return [Array<Script::Node>] The root nodes of the arguments. @raise [Sass::SyntaxError] if the argument list isn‘t valid SassScript

Parses the argument list for a mixin include.
@return [Array<Script::Node>] The root nodes of the arguments. @raise [Sass::SyntaxError] if the argument list isn‘t valid SassScript
