Clang MapReduce -- Automatic C++ Refactoring at Google Scale

Is there any place that we can watch for when this tool is released?

Really interesting :)

JuliaLLawall: we actually looked at Coccinelle before implementing the language, and found that it was not sufficient nor easy enough to extend for what we wanted to do in C++. Unfortunately C++ is a completely different beast from C - there are a lot more corner cases and little hidden things that are really important to match on.

It looks similar to what Coccinelle does, although Coccinelle provides pattern matching on the concrete syntax and allows the transformation specification to be integrated directly into the pattern specification, using a patch-like notation. It doesn't seem possible to provide an example on the youtube comment page, but there are examples on the web site. Currently, however, Coccinelle only supports C code, with a very minimal treatment of C++.

Really good talk!
