在Vim中，運行命令並將stdout重定向到特定緩沖區

Question

假設我並排打開兩個緩沖區，並將源代碼輸入緩沖區1。我想運行編譯器（或任何命令行程序），並在緩沖區2中查看其輸出（ stdout ）。

如何將當前或特定緩沖區作為stdin送入此命令行程序？ 如果不可能，我可以將源代碼保存到文件中，並指定它作為編譯器的參數； 但無論如何，我想在緩沖區2中看到輸出。

Answer 1

如果您看:h :b ：

:[N]b[uffer][!] [+cmd] [N]              :b :bu :buf :buffer E86
                Edit buffer [N] from the buffer list.  If [N] is not given,
                the current buffer remains being edited.  See :buffer-! for
                [!].  This will also edit a buffer that is not in the buffer
                list, without setting the 'buflisted' flag.
                Also see +cmd.

對於+cmd ：

                                                        +cmd [+cmd]
The [+cmd] argument can be used to position the cursor in the newly opened
file, or execute any other command:
        +               Start at the last line.
        +{num}          Start at line {num}.
        +/{pat}         Start at first line containing {pat}.
        +{command}      Execute {command} after opening the new file.
                        {command} is any Ex command.

所以：

:2b +r!date

將打開緩沖區2，並讀入date命令的輸出。

Answer 2

您可以使用:r! command :r! command執行shell命令並將其輸出讀取到當前緩沖區。
