Does this happen for you in "emacs -Q" and for every C++ > file? Yes, and yes. Here's a recipe: Create the file ~/class-3.cc with the following contents: ///////////////////////////////////////////////////////////////////////// // foo class A { struct B { int i; }; struct B { int i; }; }; ///////////////////////////////////////////////////////////////////////// (i) emacs -Q (ii) M-x load-library c-ts-mode (iii) C-x C-f ~/class-3.cc The buffer, in c++-ts-mode, has no fontification apart from the comment on its first line. > If this happens with any file and in 'emacs -Q", do you see redisplay > error messages in *Messages*? If so, what are those messages? Yes, I see a single message after the above recipe. It's: Error during redisplay: (jit-lock-function 1) signaled (treesit-query-error "Node type error at" 677 "[\"_Atomic\" \"break\" \"case\" \"const\" \"continue\" \"default\" \"do\" \"else\" \"enum\" \"extern\" \"for\" \"goto\" \"if\" \"inline\" \"register\" \"restrict\" \"return\" \"sizeof\" \"static\" \"struct\" \"switch\" \"typedef\" \"union\" \"volatile\" \"while\" \"and\" \"and_eq\" \"bitand\" \"bitor\" \"catch\" \"class\" \"co_await\" \"co_return\" \"co_yield\" \"compl\" \"\concept\" \"consteval\" \"constexpr\" \"constinit\" \"decltype\" \"delete\" \"explicit\" \"final\" \"friend\" \"mutable\" \"namespace\" \"new\" \"noexcept\" \"not\" \"not_eq\" \"operator\" \"or\" \"or_eq\" \"override\" \"private\" \"protected\" \"public\" \"requires\" \"template\" \"throw\" \"try\" \"typename\" \"using\" \"xor\" \"xor_eq\"] @font-lock-keyword-face (auto) @font-lock-keyword-face (this) @font-lock-keyword-face (virtual) @font-lock-keyword-face" "Debug the query with `treesit-query-validate'") > > I think I'm using tree-sitter-cpp version 0.22.2 as downloaded from the > > Gentoo repository.
