为了将 Uncrustify 与 Vim 正确集成,请将以下内容添加到您的 .vimrc:
" 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) 映射到组合键,也可以使用我使用的方便技巧。创建一个文件~/.vim/after/ftplugin/cpp.vim,您可以在其中覆盖任何 Vim 设置,特别是针对 C++ 的设置,并在其中添加以下行:
autocmd BufWritePre <buffer> :call Uncrustify('cpp')
这基本上添加了一个预保存挂钩。现在,当您使用 C++ 代码保存文件时,Uncrustify 将使用您之前提供的配置文件自动对其进行格式化。
例如,Java 也可以这样做:在~/.vim/after/ftplugin/java.vim 中添加:
autocmd BufWritePre <buffer> :call Uncrustify('java')
你明白了。
注意:这里介绍的所有内容都经过了很好的测试,并且我每天都在使用。
