Section: New Results
The version 2.0 of the Dedukti system, developed by Ronan Saillard, has been released in July 2013. It is based on an improved version of the -calculus modulo where rewrite rules are explicitly added  , and where the conditions for typing the rewrite rules are weakened.
This version is fully written in OCaml. It is smaller, far more efficient than the previous version, and permits to type-check much bigger files.
New features include a better reporting of errors, an interactive mode, an export functionality from Dedukti to the MMT format  , and non-linear pattern matching.
