构建更好用的终端 —— Ghostty + zinit

•by HeLong
工具开发

最近将原本的 Iterm2 + Oh My Zsh 更换为 Ghostty + zinit 配置终端，在使用的过程中优化了一下体验，给大家分享出来作为参考：

  1. 终端配置：

Ghostty的配置是以文件形式存储在$HOME/Library/Application Support/com.mitchellh.ghostty/文件下的，修改或者更新配置通过快捷键 cmd + ,使用默认程序打开配置文件，全部的配置选项在： https://ghostty.org/docs/config/reference 可以查看 贴出我的配置：

  1. zinit

zinit是一个zsh的插件管理器，可以使用 bash -c "$(curl --fail --show-error --silent --location https://raw.githubusercontent.com/zdharma-continuum/zinit/HEAD/scripts/install.sh)" 一键安装。

在这里贴出我常用的插件:

语法高亮： zinit light zdharma-continuum/fast-syntax-highlighting 自动建议： zinit light zsh-users/zsh-autosuggestions 补全： zinit light zsh-users/zsh-completions

3.优化 —— Claude自定义函数

为了避免所有内容全都堆在 ⁠.zshrc 中，我把自定义逻辑单独放在一个目录里：
image|689x209, 75%
image|689x209, 75%
其中 claude.sh 是针对claude配置切换的函数，一般来说，在使用多个公益站情况下，我们会创建多个配置文件，像这样：
图 1
图 1

那我们切换的时候就可以：claude --settings ~/.claude/settings.codex.json

但是这样命令就太长了,我们可以通过 claude-cfg [name] -c ：

后面也可以加对应的参数等等，如果不需要加参数，仅简单的新对话启动也可以使用 ccfg列出所有的配置进行选择，这个功能依赖 fzf ：

在此留下对应的文件 ~/.shell/claude.sh

# ============================================================

claude-cfg() {
    claude --settings ~/.claude/settings."$1".json "${@:2}"
}

_claude-cfg() {
    _values 'configurations' $(ls ~/.claude/settings.*.json 2>/dev/null | sed 's/.*settings\.\(.*\)\.json/\1/')
}
compdef _claude-cfg claude-cfg

ccfg() {
    local selected cfg file name url

    selected=$(
        for file in ~/.claude/settings.*.json; do
            [[ -f "$file" ]] || continue

            name="${file##*/}"
            name="${name#settings.}"
            name="${name%.json}"
            url="$(jq -r '.env.ANTHROPIC_BASE_URL // ""' "$file" 2>/dev/null)"

            printf '%s\t%s\n' "$name" "$url"
        done | sort | while IFS=$'\t' read -r name url; do
            printf '%-20s\t%s\n' "$name" "$url"
        done | fzf --height=10 --reverse --prompt="Config: "
    )

    [[ -n "$selected" ]] || return
    cfg="${selected%%[[:space:]]*}"
    claude-cfg "$cfg"
}
  1. 优化 —— 两个小功能
第一个 proxy/unproxy/proxy-status 用来给终端快速设置代理，放在~/.shell/proxy.sh

proxy() {
    local port=${1:-7890}
    export https_proxy=http://127.0.0.1:$port \
           http_proxy=http://127.0.0.1:$port \
           all_proxy=http://127.0.0.1:$port
    echo "✓ Proxy set to port $port"
}

unproxy() {
    unset https_proxy http_proxy all_proxy
    echo "✓ Proxy unset"
}

proxy-status() {
    echo "http_proxy: ${http_proxy:-未设置}"
    echo "https_proxy: ${https_proxy:-未设置}"
    echo "all_proxy: ${all_proxy:-未设置}"
}

第二个，ssh选择器，在ssh配置文件中，设置了多个机器的情况下：

# Added by OrbStack: 'orb' SSH host for Linux machines
# This only works if it's at the top of ssh_config (before any Host blocks).
# This won't be added again if you remove it.
Include ~/.orbstack/ssh/config

Host *
  SetEnv TERM=xterm-256color
  IdentityFile ~/.ssh/id_rsa_web
  ServerAliveInterval 60
Host gpu
  HostName ***
  Port 6666
  User cd
Host 2
  HostName ****
  Port 6666
  User ab

可以通过 cssh 列出所有的配置选择连接，这个功能依赖 fzf ：

文件是 ~/.shell/cssh.sh

cssh() {
    local host
    host=$(
        awk '
            BEGIN {
                current_host = ""
                current_hostname = ""
            }

            /^[[:space:]]*Host[[:space:]]+/ {
                if (current_host != "" && current_host != "*") {
                    printf "%s\t%s\n", current_host, current_hostname
                }

                current_host = $2
                current_hostname = ""
                next
            }

            /^[[:space:]]*HostName[[:space:]]+/ {
                current_hostname = $2
                next
            }

            END {
                if (current_host != "" && current_host != "*") {
                    printf "%s\t%s\n", current_host, current_hostname
                }
            }
        ' ~/.ssh/config |
        sort |
        column -t -s $'\t' |
        fzf --height=10 --reverse --prompt="SSH: " |
        awk '{print $1}'
    )

    [[ -n "$host" ]] && ssh "$host"
}

最后在 ~/.zshrc 加载 ~/.shell/ 下定义的所有函数：

# 加载自定义函数
for file in ~/.shell/*.sh; do
    [ -f "$file" ] && source "$file"
done
