[cfe-dev] Is it possible to get static analyzer fixits via libclang?

[Dan Walmsley via cfe-dev]

Thanks for the reply, my usage scenario is for ide integration rather than an end user. I understand that not all checks emit visits, but for those that do how does xcode capture this information?

Static analyzer doesn't currently produce fixits, because classes of
bugs it finds ("path-sensitive" bug reports that take a lot of different
source code locations into account, such as memory leak paths or null
dereference paths) are quite different in nature from normal warnings
issued by the compiler or lint tools like clang-tidy, and most of them
are very hard to reasonably fix automatically.


The analyzer also doesn't work when the translation unit has errors,
which seems to be your case (missing semicolon?).


I'd also hint that using the scan-build tool instead of adding --analyze
manually is usually easier for bigger projects.
