Kostis Sagonas
HiPE compiler writer and tool developer
National Technical University of Athens, Greece
Kostis Sagonas is an academic who has been involved in the development
of the Erlang language and its implementation since 1999. At Uppsala
University, he has led the development team of the HiPE native code
compiler. Together with his students he has contributed directly to
various changes and additions to the Erlang language (e.g., bit-level
pattern matching and bit-stream comprehensions, type and spec
declarations, etc.) its libraries and runtime system support for
concurrency. A hacker at heart, he has created widely used software
development tools for Erlang, like dialyzer which by now has located
literally thousands of bugs and software defects in Erlang programs. At
NTUA in Athens, he has turned his obsession for clean designs and
programs into yet another slick software tool for Erlang, called
tidier, whose details are going to be unveiled for the first time at
the Erlang Factory.

Cleaning up Erlang code is a dirty job but somebody's gotta do it
This paper is co-authored with Thanassis Avgerinos. It describes opportunities for automatically modernizing Erlang applications, cleaning them up, eliminating certain bad smells from their code, and occasionally also improving their performance. In addition, we present concrete examples of code improvements and our experiences from using a software tool with these capabilities, tidier, on Erlang code bases of significant size.
