Homebrew 的 `git` 不使用补全 [英] Homebrew’s `git` not using completion

问题描述

当使用 OSX 的 git 时，在我修改文件后，我可以简单地执行 git commit ，这会自动将文件名补全为修改后的文件名.但是，如果我从自制软件安装更新版本的 git 并使用它，该功能将不再有效(意味着我按 并且它只是询问"我想要做什么文件它打开，甚至包括那些没有变化的).

When using OSX’s git, after I modify a file I can simply do git commit <tab>, and that’ll auto complete the file’s name to the one that was modified. However, if I install a newer version of git from homebrew and I use it, that feature no longer works (meaning I press <tab> and it just "asks" me what file I want to do it on, even including the ones that have no changes).

谁能解释一下为什么，以及如何解决这个问题?我更喜欢使用 homebrew 的 git，因为它是最新的.

Can anyone shed some light as to why, and how to solve that? I’d prefer using homebrew’s git, since it’s more up-to-date.

我的 shell 是 zsh，并且安装 bash-completion 或 zsh-completion 都不起作用(即使按照 Homebrew 的安装后说明进行操作).

My shell is zsh, and Neither installing bash-completion or zsh-completions worked (even after following homebrew’s post-install instructions).

此外，在使用自制软件安装 git 后，它说

Also, after installing git with homebrew it says

Bash completion has been installed to: /usr/local/etc/bash_completion.d
zsh completion has been installed to: /usr/local/share/zsh/site-functions

所以我不应该使用其中之一吗?

So shouldn’t I be able to use one of those?

推荐答案

您正在寻找:

brew install git bash-completion

正如 warpc 的评论所述，您需要将以下内容添加到您的 ~/.bash_profile 中，以使 homebrew 的 bash-completion 工作:

As warpc's comment states, you'll need to add the following to your ~/.bash_profile to get homebrew's bash-completion working:

if [ -f $(brew --prefix)/etc/bash_completion ]; then
    . $(brew --prefix)/etc/bash_completion
fi

在安装 bash-completion 公式时的注意事项中提到了上述内容.

The above is mentioned in the caveats when you install the bash-completion formula.

注意:如果您使用 Bash v4 或更高版本(通过 brew install bash)，那么您将要使用 brew install bash-completion@2，要启用 tab 补全，将以下内容添加到 ~/.bash_profile 中，如警告中所述:

Note: if you are using Bash v4 or later (via brew install bash) then you're going to want to use brew install bash-completion@2, to enable tab completion add the following to ~/.bash_profile as described in the caveats:

export BASH_COMPLETION_COMPAT_DIR="/usr/local/etc/bash_completion.d"
[[ -r "/usr/local/etc/profile.d/bash_completion.sh" ]] && . "/usr/local/etc/profile.d/bash_completion.sh"

附加导出对于 git、docker、youtube-dl 和其他可能包含在 $(brew --prefix)/etc/bash_completion.d/ 目录中的补全来说是必要的.

The additional export is necessary for git, docker, youtube-dl, and other completions which may be included in the $(brew --prefix)/etc/bash_completion.d/ directory.
