Zsh 无法正确自动完成我的 ssh 命令

Question

我对 ssh 自动完成有一些问题。 我想让我的 zsh 在我的 .ssh/config 文件上自动完成，但直到现在它只对 /etc/hosts 文件执行此操作。 我通过添加此配置找到了如何不使用主机文件

zstyle ':completion:*:ssh:*' hosts off

但我无法成功让 zsh 查看 .ssh/config 文件 我已经尝试过，希望渺茫，但没有成功

zstyle ':completion:*:ssh:*' config on

这是我的 .zshrc 文件

    # If you come from bash you might have to change your $PATH.
    #export PATH=$HOME/bin:/usr/local/bin:/usr/local/sbin:~/Documents/workspace/flutter/bin:$PATH

    # Path to your oh-my-zsh installation.
    export ZSH=/Users/thoma/.oh-my-zsh

    # Set name of the theme to load. Optionally, if you set this to "random"
    # it'll load a random theme each time that oh-my-zsh is loaded.
    # See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes
    ZSH_THEME="agnoster"

    # Set list of themes to load
    # Setting this variable when ZSH_THEME=random
    # cause zsh load theme from this variable instead of
    # looking in ~/.oh-my-zsh/themes/
    # An empty array have no effect
    # ZSH_THEME_RANDOM_CANDIDATES=( "robbyrussell" "agnoster" )

    # Uncomment the following line to use case-sensitive completion.

    # COMPLETION_WAITING_DOTS="true"

    # Uncomment the following line if you want to disable marking untracked files

    # much, much faster.

    # Uncomment the following line if you want to change the command execution time
    # stamp shown in the history command output.

    # Set personal aliases, overriding those provided by oh-my-zsh libs,

    # users are encouraged to define aliases within the ZSH_CUSTOM folder.

    #
    # Example aliases

    export PATH="/usr/local/opt/thrift@0.9/bin:$PATH"
    zstyle ':completion:*:ssh:*' hosts off
    zstyle ':completion:*:ssh:*' config on

如果有人可以帮助我！我很乐意欣赏。

谢谢

如果您正在寻找 ssh 和其他 ssh 命令（如 scp）的自动补全功能，请使用以下几行代码：

# Highlight the current autocomplete option
zstyle ':completion:*' list-colors "${(s.:.)LS_COLORS}"

# Better SSH/Rsync/SCP Autocomplete
zstyle ':completion:*:(scp|rsync):*' tag-order ' hosts:-ipaddr:ip\ address hosts:-host:host files'
zstyle ':completion:*:(ssh|scp|rsync):*:hosts-host' ignored-patterns '*(.|:)*' loopback ip6-loopback localhost ip6-localhost broadcasthost
zstyle ':completion:*:(ssh|scp|rsync):*:hosts-ipaddr' ignored-patterns '^(<->.<->.<->.<->|(|::)([[:xdigit:].]##:(#c,2))##(|%*))' '127.0.0.<->' '255.255.255.255' '::1' 'fe80::*'

# Allow for autocomplete to be case insensitive
zstyle ':completion:*' matcher-list '' 'm:{[:lower:][:upper:]}={[:upper:][:lower:]}' \
  '+l:|?=** r:|?=**'

# Initialize the autocompletion
autoload -Uz compinit && compinit -i

这是来自related question 的脚本。

h=()
if [[ -r ~/.ssh/config ]]; then
  h=($h ${${${(@M)${(f)"$(cat ~/.ssh/config)"}:#Host *}#Host }:#*[*?]*})
fi
if [[ -r ~/.ssh/known_hosts ]]; then
  h=($h ${${${(f)"$(cat ~/.ssh/known_hosts{,2} || true)"}%%\ *}%%,*}) 2>/dev/null

if [[ $#h -gt 0 ]]; then
  zstyle ':completion:*:ssh:*' hosts $h
  zstyle ':completion:*:slogin:*' hosts $h
