Hat is a programmer's tool for generating a trace of a computation of a Haskell 98 program and viewing such a trace in various different ways. Applications include program comprehension and debugging. The trace viewing tools show expressions and equations of a computation, but they hardly refer to the source program. This disregard of the program is odd, because the computation follows from the program and the usually familiar source program can help orientation in a complex computation. Hence I started the development of new trace viewing tools that are based on showing the source program with various changing markings.
