[cfe-dev] clang-tidy in the editor

[Mark Deggeller via cfe-dev]

I have integrated clang-tidy into a text-editor project, re-running 
clang-tidy as the user types. It works, but it can be slow to reparse 
the entire file and #includes after every edit.

I've also experimented using libclang's precompiled preambles and 
clang_reparseTranslationUnit(). This works great for reparse 
performance, but I'm having trouble figuring out how to incorporate the 
clang-tidy checkers.

I would appreciate any advice on speeding up clang-tidy so that 
repeatedly reparsing a file doesn't need to reparse all the #included 
headers.

Thanks!
