iTerm2：MacOS 下使用最广泛的终端模拟器

概述​

iTerm2 只支持 MacOS，但也是 MacOS 下用的最多的终端模拟器，很成熟，根据本人的使用经验，它的渲染效果比其它终端模拟器都要好（与 Alaricity、WezTerm 等对比过），不管是中文还是英文，不管是自带显示器还是外接显示器，都能很好的渲染。相比之下，WezTerm 的中文渲染效果在外接显示器下就比较差，粗体也显示的很细，中英文混合时有时会显得比较挤。Alaricity 显示还行，但输入中文时，标点符号无法输入中文的标点。

允许应用访问粘贴板​

如果希望 tmux 中，或者在 tmux 中的 neovim 复制的文本能同步到系统粘贴板，且终端使用的是 iTerm2，需要勾选此选项：

如果使用的是 wezterm，默认不需要额外设置。

让 Alt 键生效​

有些运行在终端里的应用会使用 Alt 键作为快捷键，比如 zellij, neovim 等，而 iTerm2 默认不将 Option 键映射为 Alt 键，需要在 Settings-Profiles-Default-Keys 中，将 Left Option Key 和 Right Option Key 选到 Esc+：

改变主题​

默认主题显示的颜色太浅，有时候看起来有点吃力，可修改成其它 color scheme，在 这里 下载需要的 color scheme，比如我下载的是 tokyonight，跟我的 Neovim 里的主题一致。

下载好后在 Settings-Profiles-Default-Colors 中，点击 Color Presets，选择 Import，选择下载好的 tokyonight.itermcolors 文件进行导入：

导入后在 Color Presets 里选择 tokyonight 即可。

配置 lrzsz​

  1. 安装 lrzsz。
brew install lrzsz
  1. 写入脚本文件 /usr/local/bin/iterm2-recv-zmodem.sh。
/usr/local/bin/iterm2-recv-zmodem.sh

osascript -e 'tell application "iTerm2" to version' >/dev/null 2>&1 && NAME=iTerm2 || NAME=iTerm

if [[ $FILE = "" ]]; then
  echo Cancelled.
  # Send ZModem cancel
  echo -e \\x18\\x18\\x18\\x18\\x18
  sleep 1
  echo
  echo \# Cancelled transfer
else
  cd "$FILE"
  /opt/homebrew/bin/rz --rename --escape --binary --bufsize 4096
  sleep 1
  echo

  echo \# Sent \-\> $FILE

  1. 赋予权限。
sudo chmod 777 /usr/local/bin/iterm2-*
  1. 点击 iTerm2 的设置界面 Perference -> Profiles -> Default -> Advanced -> Triggers 的 Edit 按钮。

  1. 按照以下内容配置。
Regular expression: rz waiting to receive.\*\*B0100
            Action: Run Silent Coprocess
        Parameters: /usr/local/bin/iterm2-send-zmodem.sh
           Instant: checked

Regular expression: \*\*B00000000000000
            Action: Run Silent Coprocess
        Parameters: /usr/local/bin/iterm2-recv-zmodem.sh
           Instant: checked

  1. 搞定！可通过 rz 和 sz 命令测试（无需重启 iTerm2）。
