It has finally happened. Lutok is the result of what was promised in the "Splitting utils::lua from Kyua" web post.

Quoting the project web page:
Lutok provides thin C++ wrappers around the Lua C API to ease the interaction between C++ and Lua. These wrappers make intensive use of RAII to prevent resource leakage, expose C++-friendly data types, report errors by means of exceptions and ensure that the Lua stack is always left untouched in the face of errors. The library also provides a small subset of miscellaneous utility functions built on top of the wrappers.

Lutok focuses on providing a clean and safe C++ interface; the drawback is that it is not suitable for performance-critical environments. In order to implement error-safe C++ wrappers on top of a Lua C binary library, Lutok adds several layers or abstraction and error checking that go against the original spirit of the Lua C API and thus degrade performance.

Lutok was originally developed within Kyua but was later split into its own project to make it available to general developers.
Coming up with a name for this project was quite an odyssey, and is what has delayed is release more than I wanted. My original candidate was "luawrap" which, although not very original, was to-the-point and easy to understand. Unfortunately, that name did not clear with the legal department and I had to propose several other names, some of which were not acceptable either. Eventually, I settled with "Lutok", which comes from "LUa TOolKit".

At this point, the source tree of Lutok provides pretty much the same code as the utils::lua module of Kyua. While it may be enough to get you started, I'm pretty sure you will lack some functions in the state class. If that is the case, don't hesitate to file a bug report to let me know what is missing.

In case you missed the link above, the project page is here: Lutok in Google Code.
