export HOMEBREW_INSTALL_FROM_API=1

% man brew
...
       HOMEBREW_INSTALL_FROM_API
              If set, install formulae and casks in homebrew/core and homebrew/cask taps using Homebrew´s
              API instead of needing (large, slow) local checkouts of these repositories.

              Note: Setting HOMEBREW_INSTALL_FROM_API is not compatible with Homebrew´s developer mode so
              will error (as Homebrew development needs a full clone).

设置这个环境变量以后可以 brew untap homebrew/core brew untap homebrew/cask. 省几百 MB 空间. 先不说缺不缺这些空间, 把那十多年的 formula 历史放普通用户硬盘上本来就不科学.

副作用未知.

感觉不好用, 比如 cleanup 会卡死.

早年是 shallow clone, 没那么占空间, 后来 GitHub 说 CPU 占用太大不要 shallow.

那我们换个源吧, 他们没说不能 shallow.
export HOMEBREW_CORE_GIT_REMOTE=https://mirrors.ustc.edu.cn/homebrew-core.git
或 https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

需要改下 brew 代码, 我就不教了, 免得上面两镜像管理员来打我.

@clrss 为什么 shallow 会占 github 的 cpu 呢？
按说 git 是各版本独立保存啊，只取最后版本其实不费什么事吧
除非他们把最后一版和旧的一起 pack 了？？
