# File lib/sassc/script/value/string.rb, line 22 def self.quote(contents, opts = {}) quote = opts[:quote] # Short-circuit if there are no characters that need quoting. unless contents =~ /[\n\\"']|\#\{/ quote ||= '"' return "#{quote}#{contents}#{quote}" end if quote.nil? if contents.include?('"') if contents.include?("'") quote = '"' else quote = "'" end else quote = '"' end end # Replace single backslashes with multiples. contents = contents.gsub("\\", "\\\\\\\\") # Escape interpolation. contents = contents.gsub('#{', "\\\#{") if opts[:sass] if quote == '"' contents = contents.gsub('"', "\\\"") else contents = contents.gsub("'", "\\'") end contents = contents.gsub(/\n(?![a-fA-F0-9\s])/, "\\a").gsub("\n", "\\a ") "#{quote}#{contents}#{quote}" end
Returns the quoted string representation of ‘contents`.
@options opts :quote [String]
