以下是我的配置直接解决方案:
" wrap :cnext/:cprevious and :lnext/:lprevious
function! WrapCommand(direction, prefix)
if a:direction == "up"
try
execute a:prefix . "previous"
catch /^Vim\%((\a\+)\)\=:E553/
execute a:prefix . "last"
catch /^Vim\%((\a\+)\)\=:E\%(776\|42\):/
endtry
elseif a:direction == "down"
try
execute a:prefix . "next"
catch /^Vim\%((\a\+)\)\=:E553/
execute a:prefix . "first"
catch /^Vim\%((\a\+)\)\=:E\%(776\|42\):/
endtry
endif
endfunction
" <Home> and <End> go up and down the quickfix list and wrap around
nnoremap <silent> <Home> :call WrapCommand('up', 'c')<CR>
nnoremap <silent> <End> :call WrapCommand('down', 'c')<CR>
" <C-Home> and <C-End> go up and down the location list and wrap around
nnoremap <silent> <C-Home> :call WrapCommand('up', 'l')<CR>
nnoremap <silent> <C-End> :call WrapCommand('down', 'l')<CR>

秘密是使用:try和:catch在其他语言中一样.您正在寻找以下错误E553或E42.
nnoremap ]l :try<bar>lnext<bar>catch /^Vim\%((\a\+)\)\=:E\%(553\<bar>42\):/<bar>lfirst<bar>endtry<cr>

该命令的灵感来自Tim Pope的unimpaired.vim插件.
我也建议不要映射gn.该gn命令是非常方便的动作,对搜索模式采取行动.见:h gn.
