Aaron Ballman and I met by chance in Belfast and we discussed a way
forward towards making AST Matchers easier to use, particularly for C++
developers who are not familiar with the details of the Clang AST.
For those unaware, I expanded on this in the EuroLLVM conference this
year, and then expanded on it at ACCU:
One step in the process of getting there is changing the default
behavior of AST Matchers to ignore invisible nodes while matching using
the C++ API, and while matching and dumping AST nodes in clang-query.
I think this is the most important change in the entire proposal as it
sets out the intention of making the AST Matchers easier to use for C++
developers who are not already familiar with Clang APIs.
To that end, I've written an AST to motivate the change:
We're looking for feedback before pressing forward with the change. I
already have some patches written to port clang-tidy and unit tests to
account for the change of default.
