This is a replacement for a certain class of checks. Mostly for simple tests that are primarily pattern + reconstruction, without complex logic (at least for now). The long-term goal is to provide a concise alternative for the large majority of checks. > Is there any documentation about the benefits of this method vs the old > method? or of why we would potentially use one and not the other? There's a doc describing the framework here https://docs.google.com/document/d/1ppw0RhjwsrbBcHYhI85pe6ISDbA6r5d00ot3N8cQWeQ/edit?usp=sharing and some corresponding discussion on the cfe-dev mailing list (and in the doc comments). > Is there a change needed to add_new_check.py to have it generate this new > style?

I would hope that it will be the more common approach. At that point, we can adjust the scripts accordingly. > I do like the brevity of it and I do like the GTEST unit tests, (I struggled > more with the lit tests than anything else, mainly for python on cygwin > reasons) > > It looks good, even if it looks like I need to go learn how tooling::stencil > works... a little bit of documentation might not go a miss on how to get > started with it... Thanks. Yes, it very much requires that you familiarize yourself with Stencil and RewriteRule (Tooling/Refactoring/Stencil.h and Transformer.h). I'm not sure what more to add that is specific to clang tidy. The intent is that, if your check can be expressed as a `RewriteRule` then there's really nothing you need to know about clang-tidy beyond what's in the header file -- you just drop the rule into TransformerClangTidyCheck. If you have questions after you see the Tooling documentation, please let me know and I'm happy to expand the comments here. Both Stencil and Transformer are quite and still under active development. Once they've stabilized a bit, I also plan to send out a more general announcement about this to the cfe-dev list.
