Work backwards, a piece at a time.

The output of parsing is a piece of structured data. So you need to design
your data type. Start with the bare minimum. Write the pretty printing
code. What do the type signatures of your analysis functions look like?

E.g. "Apply markov model" is way too vague.

The key thing is to iterate and improve on the design of your data type.

Once the data type looks good, the implementation of parsing becomes clear
as day.
