I seem to have a problem with my local Vim configuration but I'm not sure what it is. I need to override some filetype-specific settings. As per multiple tutorials/howtos, I created ~/.vim/after/ftplugin/cpp.vim with appropriate setlocal statements, but it seems not to be read. I checked that ~/.vim/after is in runtimepath.

I worked around this with autocmd FileType cpp setlocal ... in ~/.vimrc, but that is beyond the point. Any advice on how to diagnose/fix this? Or am I just overlooking something obvious?

Check the output of:


You may need to add

filetype plugin on

to your .vimrc (or at least add 'plugin' to your 'filetype' setting).


A good place to start would be to use the :scriptnames command. Open a C++ file however you normally do and execute


This will show you the files that Vim has sourced since it was started.

    That's a useful tip for debugging. I used to run vim --cmd 'set verbose=2' in order to see which script files were being sourced. Commented Nov 24, 2016 at 15:42
  • Yes, very useful. I learned that, the load-order of after-plugins is not what you would think, see answer vi.stackexchange.com/a/20227/20753 about that. Commented Jun 6, 2019 at 6:00
