I have a somewhat complicated calculation programmed in Haskell.
This calculation is coded without using monads.
I want to also produce a report describing the details of this calculation
for each particular set of inputs.
e.g. Number of hours worked = 100. Gross pay per hour = 50. Total gross =
100 * 50 = 500.
But about 20 times more complicated than the above.
Naturally I need to write functions to produce the above description/report
as it should be well presented. Only showing the important parts of the
calculation in a sensible order.
But I am wondering how to combine the generation of the report with the
I think if I add the report generating functions into the calculation
functions, it will make them twice as messy, and they are already
On the other hand replicating the calculation source code twice, once
without reporting and once without seems bad.
Any suggestions on how to handle this?
