Constructor Details

- (Parser) initialize(str, filename, line = 1)

A new instance of Parser

Parameters:

  • (String, StringScanner) str — The source document to parse. Note that Parser won’t raise a nice error message if this isn’t properly parsed; for that, you should use the higher-level Sass::Engine or Sass::CSS.
  • (String) filename — The name of the file being parsed. Used for warnings.
  • (Fixnum) line (defaults to: 1) — The line on which the source string appeared, if it’s part of another document.

  expected("selector or at-rule") unless @scanner.eos?
  root
end

- (Array<String, Sass::Script::Node>?) parse_interp_ident

Parses an identifier with interpolation. Note that this won’t assert that the identifier takes up the entire input string; it’s meant to be used with StringScanners as part of other parsers.

Returns:

  • (Array<String, Sass::Script::Node>, nil) — The interpolated identifier, or nil if none could be parsed
