如何“重播”自制配方中的“注意事项”部分

Question

安装自制程序时，您偶尔会在“注意事项”部分中获得一些有用的信息，您可能想把它们藏起来。一旦在安装时显示该信息，是否有任何方法可以重播或访问该信息，或者除非您将其复制粘贴到某处，否则它会永远丢失吗？

例如

==> Caveats
To have launchd start mongodb at login:
    ln -s /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents/
Then to load mongodb now:
    launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Or, if you don't want/need launchctl, you can just run:
    mongod

如果我稍后需要的话，我可能希望能够再次看到这个和/或知道该 plist 在哪里。

tl;dr 在我安装了自制软件后，如何再次看到上面的代码片段？

Answer 1

brew info mongodb

将显示它。但是，如果您进行注意事项中建议的更改，则可能会出现其他更适合您实际情况的注意事项。

Answer 2

我为此创建了一个brew外部命令：https://github.com/rafaelgarrido/homebrew-caveats

$ brew caveats zsh
==> zsh: Caveats
Add the following to your zshrc to access the online help:
    unalias run-help
    autoload run-help
    HELPDIR=/usr/local/share/zsh/helpfiles

您还可以传递多个公式：

$ brew caveats rabbitmq mongodb
==> rabbitmq: Caveats
Management Plugin enabled by default at http://localhost:15672

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

To have launchd start rabbitmq at login:
  ln -sfv /usr/local/opt/rabbitmq/*.plist ~/Library/LaunchAgents
Then to load rabbitmq now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.rabbitmq.plist
Or, if you don't want/need launchctl, you can just run:
  rabbitmq-server

==> mongodb: Caveats
To have launchd start mongodb at login:
  ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents
Then to load mongodb now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Or, if you don't want/need launchctl, you can just run:
  mongod --config /usr/local/etc/mongod.conf

当您需要检查一些配置时非常方便！

Answer 3

要查看当前安装的公式的所有注意事项，您可以使用以下命令

brew info $(brew list)

您还可以使用 awk 过滤输出以仅获取警告部分。 （我是 awk 新手，欢迎提出建议或编辑）

brew info $(brew list) | awk '/^==> Caveats$/,/^[a-z][a-zA-Z0-9_+-]+: stable |^==> (Dependencies|Options)$/'

Answer 4

另一种可能性是使用 sed

brew info $(brew list) | sed '/==> Caveats/,/==>/!d;//d'

并有一个格式化的输出（bash）

for cmd in $(brew list); do 
  if brew info $cmd | grep -q Caveats; then
    echo "$cmd\n"; 
    brew info $cmd | sed '/==> Caveats/,/==>/!d;//d'; 
    printf '%40s\n' | tr ' ' -; 
  fi; 
done;

Answer 5

对于那些拥有很棒的

jq

工具的人：

# For brews
$ brew list --formula | xargs brew info --json | jq -r '.[] | select(.caveats != null) | "\n\nName: \(.name)\nCaveats: \(.caveats)"'

# For casks
$ brew list --cask | xargs brew info --cask --json=v2 | jq -r '.casks[] | select(.caveats != null) | "\n\nName: \(.name)\nCaveats: \(.caveats)"'

jq

是一个命令行 JSON 处理器。

Answer 6

更新并组合上面的一些答案，这是一个 bash/zsh 循环，可以将其粘贴到终端中以获取所有已安装的冲泡公式的所有警告。

for x in $(brew list --formula); do 
    cavs=$(brew info "$x" | sed '/==> Caveats/,/==>/!d;//d')
    if [ ! -z "$cavs" ]; then
        echo "$x"
        echo "---"
        echo "$cavs"
        echo ""
    fi
done
