module SCSS
# A parser for a static SCSS tree.
# Parses with SCSS extensions, like nested rules and parent selectors,
# but without dynamic SassScript.
# This is useful for e.g. \{#parse\_selector parsing selectors}
# after resolving the interpolation.
class StaticParser < Parser
# Parses the text as a selector.
#
# @param line [Fixnum] The line on which the selector appears.
# Used for error reporting
# @param filename [String, nil] The file in which the selector appears,
# or nil if there is no such file.
# Used for error reporting
# @return [Selector::CommaSequence] The parsed selector
# @raise [Sass::SyntaxError] if there's a syntax error in the selector
