# File 'lib/syntax_tree/node.rb', line 9133 def format(q) # If we're in the modifier form and we're modifying a `begin`, then this # is a special case where we need to explicitly use the modifier form # because otherwise the semantic meaning changes. This looks like: # # begin # foo # end until bar # # Also, if the statement of the modifier includes an assignment, then we # can't know for certain that it won't impact the predicate, so we need to # force it to stay as it is. This looks like: # # foo = bar until foo # if statement.is_a?(Begin) || ContainsAssignment.call(statement) q.format(statement) q.text(" until ") q.format(predicate) else LoopFormatter.new("until", self, statement).format(q) end end |
