VIM过滤器和stdout/stderr

您可以使用python来区分stdout和stderr:

python import vim, subprocess
python b=vim.current.buffer
python line=vim.current.range.start
python p=subprocess.Popen(["command", "argument", ...], stdout=subprocess.PIPE, stderr=subprocess.PIPE, close_fds=True)
python returncode=p.poll()
python if not returncode: b.append(("STDOUT:\n"+p.stdout.read()+"\nSTDERR:\n"+p.stderr.read()).split("\n"), line)

:!{cmd} 执行 {cmd} 有壳有套 v:shell_error .

如果您碰巧设置了调用过滤器的映射,则可以执行以下操作:

function! UndoIfShellError()
    if v:shell_error
        undo
    endif
endfuntion

nmap <leader>filter :%!/path/to/filter<CR>:call UndoIfShellError()<CR>

另一种方法是运行filter命令,例如修改磁盘上的文件。

例如,对于gofmt(www.golang.org),我已经准备好了这些映射:

map <f9> :w<CR>:silent !gofmt -w=true %<CR>:e<CR>
imap <f9> <ESC>:w<CR>:silent !gofmt -w=true %<CR>:e<CR>

说明: 保存文件 :静音-避免在末尾按Enter键 %-将文件传递给gofmt -w=真-告诉gofmt写回文件 :e-告诉VIM重新加载修改过的文件

这就是我最后所做的:

function MakeItAFunction(line1, line2, args)
  let l:results=system() " call filter via system or systemlist
  if v:shell_error
    "no changes were ever actually made!
    echom "Error with etc etc"
    echom results
  endif
  "process results if anything needed?

  " delete lines but don't put in register:
  execute a:line1.",".a:line2." normal \"_dd"
  call append(a:line1-1, l:result)  " add lines
  call cursor(a:line1, 1)  " back to starting place
  " echom any messages
endfunction
command -range <command keys> MakeItAFunction(<line1>,<line2>,<q-args>) 
"                                         or <f-args>, etc.

它很复杂,但它很管用,而且使用后,它相当透明和优雅。希望这有任何帮助!
