Holds variables. Variables are only loaded "just in time" and are not evaluated as part of the render stage
{{ monkey }} {{ user.name }}
Variables can be combined with filters:
{{ user | link }}
# File lib/liquid/variable.rb, line 17 def initialize(markup) @markup = markup @name = nil @filters = [] if match = markup.match(/\s*(#{QuotedFragment})(.*)/) @name = match[1] if match[2].match(/#{FilterSeparator}\s*(.*)/) filters = Regexp.last_match(1).scan(FilterParser) filters.each do |f| if matches = f.match(/\s*(\w+)(?:\s*#{FilterArgumentSeparator}(.*))?/) filtername = matches[1] filterargs = matches[2].to_s.scan(/(?:\A|#{ArgumentSeparator})\s*((?:\w+\s*\:\s*)?#{QuotedFragment})/).flatten @filters << [filtername, filterargs] end end end end end
