Description

Running :FormatCode on a cpp source (not header) file causes a trailing line filled with whitespaces to appear at the end of the document.
Running :FormatCode again and again removes and re-adds and removes and ... this line.

Steps to reproduce

1. Use this init.vim file:

call plug#begin('~/.local/share/nvim/plugged-minimal') Plug 'google/vim-maktaba' " Needed for vim-codefmt Plug 'google/vim-glaive' " Needed for vim-codefmt Plug 'google/vim-codefmt' " Code formatting call plug#end() 

2. Open any .cc file (for example I use base/run_loop.cc from the chromium project

3. Run :FormatCode. Observe line with trailing whitespaces at the end of the file

4. Run :FormatCode. Observe line with trailing whitespaces at the end of the file is gone.

5. Repeat

My Setup

• 'vim-codefmt' is up-to-date (I ran :PlugUpdate)

─❯ nvim --version NVIM v0.7.2 

╰─❯ clang-format --version clang-format version google3-trunk (30af2fb33ed2f610abfa50e53df9712887b2bd25) 

Gif of the bug

Other things I tried

• Manually running clang-format -i base/run_loop.cc from the command line does not introduce these whitespaces, which is why I opened the bug against vim-codefmt and not clang-format.

Please let me know if you need any more information.

Thanks!
