在Vim中将缓冲区缓冲到外部命令 [英] Piping buffer to external command in Vim

问题描述

我是Vim的新手.我想将当前缓冲区的内容发送到外部命令的stdin(比如说mail).我的最终目的是设置快捷方式，以从当前Vim缓冲区快速发送电子邮件.我猜这应该是一件小事，但我找不到将Vim缓冲区发送到外部命令的方法.预先感谢.

I am kind of a Vim novice. I would like to send contents of the current buffer to stdin of external command (lets say mail). My final purpose is to set a shortcut to quickly send email from current Vim buffer. I am guessing this should be a trivial stuff, but I couldn't find a way to send Vim buffer to an external command. Thanks in advance.

推荐答案

您可以使用:w !cmd将当前缓冲区写入外部命令的stdin.来自:help :w_c:

You can use :w !cmd to write the current buffer to the stdin of an external command. From :help :w_c:

:[range] w [rite] [++ opt]！{cmd}

以[range]行作为标准输入执行{cmd}(请注意'!'前面的空格). {cmd}的执行方式与":!{cmd}"相同，任何'!'都将替换为先前的命令|:!|.

:[range]w[rite] [++opt] !{cmd}

Execute {cmd} with [range] lines as standard input (note the space in front of the '!'). {cmd} is executed like with ":!{cmd}", any '!' is replaced with the previous command |:!|.

一个相关的命令是:%!cmd，它执行相同的操作，然后用命令的输出替换当前缓冲区.因此:%!sort会调用外部sort命令对当前缓冲区进行排序.

A related command is :%!cmd which does the same thing and then replaces the current buffer with the output of the command. So :%!sort would invoke the external sort command to sort the current buffer in place.
