Taking the Pain Out of Debugging With Live Programming

angry tapir writes "'Everyone knows that debugging is twice as hard as writing a program in the first place,' Brian Kernighan once wrote (adding: 'So if you're as clever as you can be when you write it, how will you ever debug it?') However, Sean McDirmid, a researcher at Microsoft, has been working to remove some of the pain from debugging. McDirmid, based at Microsoft Research Asia, has been studying ways of implementing usable live programming environments: a solution that is less intrusive than classical debuggers. The idea is to essentially provide a programming environment in which editing of code and the execution of code occur simultaneously — and in the same interface as code editing — with tools to track the state of variables in a more or less live manner."
