An operator-separated sequence of {SimpleSequence simple selector sequences}.
The array of {SimpleSequence simple selector sequences}, operators, and newlines. The operators are strings such as `“+”` and `“>”` representing the corresponding CSS operators, or interpolated SassScript. Newlines are also newline strings; these aren’t semantically relevant, but they do affect formatting.
@return [Array<SimpleSequence, String|Array<Sass::Tree::Node, String>>]
@param seqs_and_ops [Array<SimpleSequence, String|Array<Sass::Tree::Node, String>>]
See \{#members}
# File lib/sass/selector/sequence.rb, line 38 def initialize(seqs_and_ops) @members = seqs_and_ops end
Add to the {SimpleSequence#sources} sets of the child simple sequences. This destructively modifies this sequence’s members array, but not the child simple sequences.
@param sources [Set<Sequence>]
# File lib/sass/selector/sequence.rb, line 138 def add_sources!(sources) members.map! {|m| m.is_a?(SimpleSequence) ? m.with_more_sources(sources) : m} end
Non-destructively extends this selector with the extensions specified in a hash (which should come from {Sass::Tree::Visitors::Cssize}).
@overload do_extend(extends, parent_directives)
@param extends [Sass::Util::SubsetMap{Selector::Simple => Sass::Tree::Visitors::Cssize::Extend}] The extensions to perform on this selector @param parent_directives [Array<Sass::Tree::DirectiveNode>] The directives containing this selector.
@return [Array<Sequence>] A list of selectors generated
by extending this selector with `extends`. These correspond to a {CommaSequence}'s {CommaSequence#members members array}.
# File lib/sass/selector/sequence.rb, line 91 def do_extend(extends, parent_directives, seen = Set.new) extended_not_expanded = members.map do |sseq_or_op| next [[sseq_or_op]] unless sseq_or_op.is_a?(SimpleSequence) extended = sseq_or_op.do_extend(extends, parent_directives, seen) choices = extended.map {|seq| seq.members} choices.unshift([sseq_or_op]) unless extended.any? {|seq| seq.superselector?(sseq_or_op)} choices end weaves = Sass::Util.paths(extended_not_expanded).map {|path| weave(path)} trim(weaves).map {|p| Sequence.new(p)} end
Sets the name of the file in which this selector was declared, or `nil` if it was not declared in a file (e.g. on stdin). This also sets the filename for all child selectors.
@param filename [String, nil] @return [String, nil]
# File lib/sass/selector/sequence.rb, line 22 def filename=(filename) members.each {|m| m.filename = filename if m.is_a?(SimpleSequence)} filename end
Returns a string representation of the sequence. This is basically the selector string.
@return [String]
# File lib/sass/selector/sequence.rb, line 129 def inspect members.map {|m| m.inspect}.join(" ") end
Sets the line of the Sass template on which this selector was declared. This also sets the line for all child selectors.
@param line [Fixnum] @return [Fixnum]
# File lib/sass/selector/sequence.rb, line 11 def line=(line) members.each {|m| m.line = line if m.is_a?(SimpleSequence)} line end
Resolves the {Parent} selectors within this selector by replacing them with the given parent selector, handling commas appropriately.
@param super_cseq [CommaSequence] The parent selector @param implicit_parent [Boolean] Whether the the parent
selector should automatically be prepended to the resolved selector if it contains no parent refs.
@return [CommaSequence] This selector, with parent references resolved @raise [Sass::SyntaxError] If a parent selector is invalid
# File lib/sass/selector/sequence.rb, line 52 def resolve_parent_refs(super_cseq, implicit_parent) members = @members.dup nl = (members.first == "\n" && members.shift) contains_parent_ref = members.any? do |seq_or_op| seq_or_op.is_a?(SimpleSequence) && seq_or_op.members.first.is_a?(Parent) end return CommaSequence.new([self]) if !implicit_parent && !contains_parent_ref unless contains_parent_ref old_members, members = members, [] members << nl if nl members << SimpleSequence.new([Parent.new], false) members += old_members end CommaSequence.new(Sass::Util.paths(members.map do |sseq_or_op| next [sseq_or_op] unless sseq_or_op.is_a?(SimpleSequence) sseq_or_op.resolve_parent_refs(super_cseq).members end).map do |path| Sequence.new(path.map do |seq_or_op| next seq_or_op unless seq_or_op.is_a?(Sequence) seq_or_op.members end.flatten) end) end
Returns whether or not this selector matches all elements that the given selector matches (as well as possibly more).
@example
(.foo).superselector?(.foo.bar) #=> true (.foo).superselector?(.bar) #=> false (.bar .foo).superselector?(.foo) #=> false
@param sseq [SimpleSequence] @return [Boolean]
# File lib/sass/selector/sequence.rb, line 112 def superselector?(sseq) return false unless members.size == 1 members.last.superselector?(sseq) end
@see Simple#to_a
# File lib/sass/selector/sequence.rb, line 118 def to_a ary = @members.map do |seq_or_op| seq_or_op.is_a?(SimpleSequence) ? seq_or_op.to_a : seq_or_op end Sass::Util.intersperse(ary, " ").flatten.compact end
