我有一个别名g='git'，结合我的git别名，我键入如下内容

$ g co <branchname>

对于我的特定用例，更简单的解决方法是在git-completion中添加一行代码。

就在这条线下面:

__git_complete git _git

我添加了这一行来处理我的单个'g'别名:

__git_complete g _git

Felipe Contreras对Git补全功能(参见Git 2.30中的Zsh补全)非常积极，他提出(可能是Git 2.31, Q1 2021)一个公共函数将有助于别名自动补全。

他的建议:

Back in 2012 I argued for the introduction of a helper that would allow users to specify aliases like: git_complete gf git_fetch Back then there was pushback because there was no clear guideline for public functions (git_complete vs _git_complete vs _GIT_complete), and some aliases didn't actually work. Fast-forward to 2020 and there's still no guideline for public functions, and those aliases still don't work (even though I sent the fixes). This has not prevented people from using this function that is clearly needed to setup custom aliases (this page), and in fact it's the recommended way. But it is cumbersome that the user must type: __git_complete gf _git_fetch Or worse: __git_complete gk __gitk_main 8 years is more than enough time to stop waiting for the perfect to come; let's define a public function (with the same name) that is actually user-friendly: __git_complete gf git_fetch __git_complete gk gitk While also maintaining backwards compatibility. The logic is: If $2 exists, use it directly If not, check if __$2_main exists If not, check if _$2 exists If not, fail

您还可以尝试使用Git别名。例如，在我的~/。gitconfig文件，我有一个看起来像这样的部分:

[alias]
        co = checkout

所以你可以输入git com <TAB>，这应该扩展到git co master，这是git checkout命令。

我知道这个问题是关于bash的，但如果你使用zsh，这个改变@hesky-fisher回答将修复它。

From

# For each defined alias, extract the necessary elements and use them
# to call wrap_alias.
eval "$(alias -p | sed -e 's/alias \([^=][^=]*\)='\''\([^ ][^ ]*\) *\(.*\)'\''/wrap_alias \1 \2 '\''\3'\'' /')"

to:

# For each defined alias, extract the necessary elements and use them
# to call wrap_alias.
eval "$(alias | sd '^([^=]+)=(.+)' 'wrap_alias $1=$2')"

你需要sd(这可以用sed代替，但sd在我看来更好)

这样做是因为zsh没有别名-p，并且zsh中的别名输出不输出

alias <something>=<value>

就像在狂欢，但是

<something>=<value>

顺便说一下，我把初始化代码放在。zlogin文件中

在git-completion。Bash有一行:

complete -o default -o nospace -F _git git

查看这一行(和_git函数)，你可以将这一行添加到你的.bash_profile:

complete -o default -o nospace -F _git_checkout gco

如果你使用别名g='git'，我将这行代码添加到.bash_aliases中

complete -o default -o nospace -F _git g
