我的项目中有以下代码:

class RangeConverter {
private:
    struct Converter {
                    double MinimumInput;
                    double MaximumInput;

                    double MinimumOutput;
                    double MaximumOutput;

                    template <typename RangeType>
                    RangeType Convert ( RangeType invalue ) const {
                        double v = static_cast<double> ( invalue );
                        if ( v < MinimumInput ) {
                            v = MinimumInput;
                        } else if ( v > MaximumInput ) {
                            v = MaximumInput;
                        }
                        double interpolationfactor = ( v - MinimumInput ) / ( MaximumInput - MinimumInput );
                        return static_cast<RangeType> ( ( interpolationfactor * ( MaximumOutput - MinimumOutput ) ) + MinimumOutput );
                    }
                };
.....

用AStyle格式化该代码后,我得到以下信息:
class RangeConverter {
private:
    struct Converter {
        ngeConverter {
        private:
            struct Converter {
                double MinimumInput;
                double MaximumInput;

                double MinimumOutput;
                double MaximumOutput;

                template <typename RangeType>
                RangeType Convert ( RangeType invalue ) const {
                    double v = static_cast<double> ( invalue );
                    if ( v < MinimumInput ) {
                        v = MinimumInput;
                    } else if ( v > MaximumInput ) {
                        v = MaximumInput;
                    }
                    double interpolationfactor = ( v - MinimumInput ) / ( MaximumInput - MinimumInput );
                    return static_cast<RangeType> ( ( interpolationfactor * ( MaximumOutput - MinimumOutput ) ) + MinimumOutput );
                }
            };
.....

astyle命令:
astyle
    \   --style=java
    \   --indent=force-tab=2
    \   --indent-classes
    \   --indent-switches
    \   --indent-labels
    \   --indent-preprocessor
    \   --indent-col1-comments
    \   --pad-oper
    \   --pad-paren
    \   --delete-empty-lines
    \   --add-brackets
    \   --align-pointer=type
    \   --align-reference=type

那是astyle的错误,还是我忘记了任何选择?
如果是错误,您建议用VIM格式化C++代码吗?

最佳答案

当然,这是一个错误。这些天对AStyle的支持不佳。有很多错误永远存在在那里并且从未得到解决。您不应该期望这种情况在不久的将来会有所改善。我强烈建议切换到Uncrustify。当然,它也有一些问题,但是它们不是那么讨厌,并且不会像AStyle那样破坏您的代码。它具有数百种配置选项-比AStyle灵活得多-因此请耐心等待,您需要花费一些时间来根据自己的口味和习惯进行调整。

完成后,如果您想将其正确地与Vim集成,请在此处输入可以添加到.vimrc中的代码:

" Restore cursor position, window position, and last search after running a
" command.
function! Preserve(command)
  " Save the last search.
  let search = @/

  " Save the current cursor position.
  let cursor_position = getpos('.')

  " Save the current window position.
  normal! H
  let window_position = getpos('.')
  call setpos('.', cursor_position)

  " Execute the command.
  execute a:command

  " Restore the last search.
  let @/ = search

  " Restore the previous window position.
  call setpos('.', window_position)
  normal! zt

  " Restore the previous cursor position.
  call setpos('.', cursor_position)
endfunction

" Specify path to your Uncrustify configuration file.
let g:uncrustify_cfg_file_path =
    \ shellescape(fnamemodify('~/.uncrustify.cfg', ':p'))

" Don't forget to add Uncrustify executable to $PATH (on Unix) or
" %PATH% (on Windows) for this command to work.
function! Uncrustify(language)
  call Preserve(':silent %!uncrustify'
      \ . ' -q '
      \ . ' -l ' . a:language
      \ . ' -c ' . g:uncrustify_cfg_file_path)
endfunction

现在,您可以将此函数(Uncrustify)映射到键的组合,也可以执行我使用的便捷技巧。创建一个~/.vim/after/ftplugin/cpp.vim文件,您可以在其中覆盖任何Vim设置,尤其是C++,并在其中添加以下行:
autocmd BufWritePre <buffer> :call Uncrustify('cpp')

这基本上增加了一个预保存的钩子(Hook)。现在,当您使用C++代码保存文件时,Uncrustify会利用您先前提供的配置文件自动将其格式化。

注意:这里介绍的所有内容都经过我每天的严格测试和使用。
