如何在 tmux 中强制使用 emacs 样式的状态键?

问题描述

我在使用 tmux 1.8 时遇到了这个问题:我想将 status-keys 选项设置为emacs"，因为我真的不喜欢在 vi 模式下输入命令.但是，将以下行添加到 .tmux.conf 没有任何效果:

I have this problem with tmux 1.8: I want to set status-keys option to 'emacs' because I really dislike entering commands in vi-mode. However adding the following line to .tmux.conf has no effect:

set -g status-keys emacs

tmux 重启时，tmux show-options -g |grep keys 说 emacs 但实际行为是 vi 风格的.

When tmux is restarted, tmux show-options -g | grep keys says emacs but the actual behaviour is vi-style.

问题的根源在于 $EDITOR 环境变量，在我的例子中它设置为 vim.文档说明:

The root of the problem is the $EDITOR environment variable, which it set to vim in my case. The documentations states:

status-keys [vi | emacs]
    Use vi or emacs-style key bindings in the status line,
    for example at the command prompt.  The default is emacs,
    unless the VISUAL or EDITOR environment variables are set
    and contain the string `vi'.

很明显，当环境变量是vim"时，它会强制使用 vi 状态键.

So apparently when the environment variable is "vim" it forces vi status-keys.

有没有办法覆盖此行为并使提示行为类似于 emacs 风格，尽管环境变量存在?我显然可以解决这个问题(比如用其他 env 变量启动 tmux 并稍后恢复原来的)，但我希望有一个干净的解决方案.

Is there a way to override this behaviour and have the prompt behave emacs-style despite the environment variable? I can obviously hack around this (like starting tmux with other env variables and restoring the original later) but I hope there is a clean solution.

谢谢！

推荐答案

我遇到了这个问题，我想我刚刚想通了.您是否偶然也在使用 ZSH (Z Shell)?

I had this problem and I think I just figured it out. Are you by chance also using ZSH (Z Shell)?

我发现这篇文章 说 ZSH 也将切换到如果您的 VISUAL 和/或 EDITOR 设置为 vi/vim，则为vi 模式".所以我在 tmux 中遇到的问题实际上是从 ZSH 冒出来的！

I found this post that says that ZSH will also switch to "vi mode" if your VISUAL and/or EDITOR is set to vi/vim. So the problem I was having in tmux as actually bubbling up from ZSH!

简而言之，请确保您可以在 tmux 之外的 shell 中使用 emacs 样式的键.如果您使用 ZSH，您可以将 bindkey -e 添加到 .zshrc 以设置 emacs 绑定.然后在 .tmux.conf:

In short, make sure you can use emacs-style keys in your shell outside of tmux. If you're using ZSH you can add bindkey -e to .zshrc to set emacs bindings. Then in .tmux.conf:

set -g mode-keys emacs
set -g status-keys emacs
