Return a copy of ourselves that can be modified without affecting us
# File rdoc/template.rb, line 112 def dup LineReader.new(@lines.dup) end
read the next line
# File rdoc/template.rb, line 92 def read @lines.shift end
Return a list of lines up to the line that matches a pattern. That last line is discarded.
# File rdoc/template.rb, line 98 def read_up_to(pattern) res = [] while line = read if pattern.match(line) return LineReader.new(res) else res << line end end raise "Missing end tag in template: #{pattern.source}" end
