vim-clang-format attempts to use Vim's indentation configuration (expandtab and shiftwidth). So, if you want to fix them, you need to fix it by configuration.

Below configuration fixed this problem.

let g:clang_format#style_options = { 
            \ "Standard" : "C++11",
            \ "IndentWidth" : 4,
            \ "UseTab" : "false",
            \ "AccessModifierOffset" : -2,
            \ "ColumnLimit" : 0 }

Oh, it caused because of the difference of indentation. Your Vim is configured 2 indentation and formatter is configured 4 indentation, right? Then when pasting the formatted result, Vim tried to set indentation to 4 spaces.

We need to ignore indentation configuration at pasting the formatted result.

I couldn't reproduce this. Could you provide more information to reproduce?

[372046933]

@rhysd It happens every time. I do now know what info may be helpful to you. So only version info is printed

Could you test below sequence in your environment?

1. :set paste
2. Select whole region with ggvG
3. :ClangFormat

Does this resolve the indent problem?

[372046933]

@rhysd Tried the advice you gave, but still the same issue.

[372046933]

@rhysd My colleague found the trick. Hope it helps!

[tx@arch ~]$ diff .vim/bundle/vim-clang-format/autoload/clang_format.vim clang_format.vim 
65c65
<     return printf("'{BasedOnStyle: %s, IndentWidth: %d, UseTab: %s%s}'",
---
>     return printf("'{BasedOnStyle: %s, IndentWidth: 4, UseTab: false%s}'",
67,68d66
<                         \ (exists('*shiftwidth') ? shiftwidth() : &l:shiftwidth),
<                         \ &l:expandtab==1 ? "false" : "true",

[rhysd]

Thank you for investigation.

It looks a problem related to indentation configuration. I guess :echo shiftwidth() shows 2 in your environment, right?

[372046933]

@rhysd Actually, it is 8 and shiftwidthwas not set in .vimrc

[rhysd]

Could you show me the indentation configuration in your vimrc? I'll be able to try.

[372046933]

set formatoptions+=m
set autoindent
set tabstop=4
set shiftwidth=4
set textwidth=72
set cinoptions+=g0

[wokalski]

If anyone else encounters this issue, try setting expandtab. shiftwidth causes the indentation issues but if you set expandtab everything works as expected.

[rhysd]

@wokalski Nice. So we need to set expandtab while formatting. If fix the value, we can no longer format with hard tabs...
