Bug Summary and Steps to Reproduce

Bug Summary: I am trying to create a template class separating its declaration in .h file and its implementation in .tpp file. Both files have #pragma once and the code compiles correctly, everything works, except the intellisense . It's arguing about redefinition error.

This error happens in my MyArray.tpp file:

redefinition of 'MyArray<T, n>'C/C++(clang-diagnostic-error)
MyArray.tpp(6, 16): previous definition is here
template<class T, size_t n> MyArray<T, n>::MyArray(std::initializer_list<T> elements)

Steps to reproduce:

  1. Create include/<file>.tpp and <file>.h , create main.cpp
  2. write declaration and implementation code
  3. #include "<file>.tpp" on the bottom of <file>.h and #include <file>.h on the top of <file>.tpp

Expected behavior: intellisense should not be confused. The exact code works well in Visual Studio

    I think the problem is that clang-tidy.exe runs for MyArray.tpp

    Boris Hubavenski (@bhubavenski) The .txx is missing from our code that handles C++ header extensions so it's incorrectly create a separate TU for the .txx instead of using the .cpp, which works if the .txx file is .tcc instead.

    Sean McManus (@sean-mcmanus) Hello! I tried your advice to use .tcc, but doesn't seems to do anything different than just changing the file icon from c++ to h++ ( because of the material icons extension ). The error of type "redefinition of ... " is still there. Interestingly I also tried your advice on a fresh new project and there it worked correct, no errors, but both projects are bare bones and both have same configuration in them, there are really no big difference. Why in the one it works and on the other it doesn't? I see that on the one where are the erros, clang-tidy tries to compile the tcc file, but in the other project it doesn't

    Also, I noticed that the .tcc file is not recognized as C++ syntax but as plain text. I already tried switching the language mode manually, which works, but is there anything else I should configure to make the C++ extension work properly with this file type? IntelliSense seems to work for now, but I’m wondering if there are other settings I should adjust to ensure full support.

    also the automatic option for "Code Analysis" is not exactly automatic, or its mostly random. Sometimes its triggered automatically and sometimes its triggered on CTRL + S and sometimes I need to trigger it manually

    Boris Hubavenski (@bhubavenski) You can set files.associations for .tcc/.tpp/.txx .

    The runAutomatically applies when a file is opened or saved.

    If you see issues with the .tcc file, what do you see when run C/C++: Log Diagnostics in regards to which TU is being created, i.e. are you seeing the .tcc file get it's own TU? Does another .cpp file include that .tcc file? It's supposed to create a TU with just the .cpp file.

    Boris Hubavenski (@bhubavenski) Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/v1.27.0 . Let us know if you still have an issue since we may have not had the same repro scenario.
