nomeata’s mind shares: Talk and Article on Monads for Reverse Engineering

In a recent project of mine, a tool to analyze and create files for the Ravensburger Tiptoi pen, I used two interesting Monads with good results:

  • A parser monad that, while parsing, remembers what part of the file were used for what and provides, for example, an annotated hex dump.
  • A binary writer monad that allows you to reference and write out offsets to positions in the file that are only determined “later” in the monad, using MonadFix.

As that’s quite neat, I write a blog post for the German blog funktionale-programmierung.de about it, and also held a talk at the Karlsruhe functional programmers group. If you know some German, enjoy; if not, wait until I have a reason to hold the talk in English. (As a matter of fact, I did hold the talk in English, but only spontaneously, so the text is in German only so far.)

Don't be the product, buy the product!
