管道 Vim 缓冲区到标准输出 [英] Pipe Vim buffer to stdout

问题描述

我想在管道中间使用 Vim.这个现有帖子看起来像我想要的要做，除非我希望在没有 Python 帮助的情况下做到这一点——只有使用 bash.[它有帮助，环境是 Android 上终端 IDE 应用程序中的 bash shell.]

I'd like to use Vim in the middle of a pipe. This existing post looks like what I'd like to do, except I was hoping to do it without Python's help -- only with bash. [It it helps, the environment is the bash shell in the Terminal IDE app on Android.]

拜托，我知道如何通过内部 Vim 的命令通过管道传输缓冲区.这很好，但不是我想要的.我想退出 Vim 并将活动缓冲区传递给 stdout.

Please, I know how to pipe a buffer through a command from inside Vim. That's great, but not what I want here. I want to exit Vim and pass the active buffer to stdout.

FWIW，我也知道如何将另一个命令作为输入传递给 Vim.再说一次，这不是我想要的.

FWIW, I also know how to pass another command into Vim as input. Again, that's not what I'm trying to get here.

推荐答案

查看 vipe，它是 moreutils.它允许您将任何编辑器用作管道的一部分.

Take a look at vipe which is part of moreutils. It allows you to use any editor as part of a pipe.

 ls -al | vipe | less

要将它与 vim 一起使用，只需确保在 bashrc 或 cshrc 或您使用的任何 shell 中将其设置为默认编辑器.

To use it with vim just make sure to set it as your default editor in your bashrc or cshrc or whatever shell you use.

 EDITOR=vim

更新:如果你想要一个 bash 唯一的解决方案，你可以使用这样的脚本

UPDATE: If you want a bash only solution you could use a script like this

 #!/bin/bash
 # create temporary file
 TMPFILE=`mktemp /tmp/vipe.bashXXXXXXXX`
 cat > ${TMPFILE}
 vim ${TMPFILE} < /dev/tty > /dev/tty
 cat ${TMPFILE}
 rm ${TMPFILE}

对于更便携的版本，请更换

For a more portable version please replace

 vim ${TMPFILE}

与

 ${EDITOR} ${TMPFILE}
