+
+`powerAssertContext` reducer function to parse assertion expression at runtime.
+
+Use this function when transpiler side does not add `ast`, `tokens` and `visitorKeys` at compile time.
+
+
+API
+---------------------------------------
+
+### var appendAst = require('power-assert-context-reducer-ast');
+### var appendedContext = appendAst(powerAssertContext);
+
+Given `powerAssertContext` object, having structure below but does not have `ast`, `tokens` and `visitorKeys`, append them to output context.
