@@ -147,6 +147,15 @@ Change log for the astroid package (used to be astng) We are also exposing a new method for UnaryOps, called `type_errors`, which returns a list of UnaryOperationsError. + * A new method was added to the AST nodes, 'bool_value'. It is used to deduce + the value of a node when used in a boolean context, which is useful + for both inference, as well as for data flow analysis, where we are interested + in what branches will be followed when the program will be executed. + `bool_value` returns True, False or YES, if the node's boolean value can't + be deduced. The method is used when inferring the unary operand `not`. + Thus, `not something` will result in calling `something.bool_value` and + negating the result, if it is a boolean. + 2015-03-14 -- 1.3.6 |
