Started coding a C parser (which will hopefully lead on to a C++ parser) in Haskell. I'm using the "happy" parser generator, which does some nifty things. I was surprised that generating a list of tokens is much slower than using a continuation based lexer, but that could explain my binary parser's memory profile. The parser will hopefully lead to some helpful tools...

Bought and started reading Martin Fowler's Refactoring book. I seem to use lots of his tricks already, but some of them like the "null object" are new. Tool support would certainly help, since one sometimes breaks things when refactoring designs which have no tests. Like I did last Friday :-(
